Significant Accounting Policies [Text Block] | 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Consolidation and Variable Interest Entities The condensed consolidated financial statements of the Company include, after eliminating intercompany balances and transactions, the accounts of the parent holding company and each of its subsidiaries, including Consolidated SCE&G. Accordingly, discussions regarding the Company's financial results necessarily include the results of Consolidated SCE&G. SCE&G has determined that it has a controlling financial interest in GENCO and Fuel Company (which are considered to be VIEs) and, accordingly, Consolidated SCE&G's condensed consolidated financial statements include the accounts of SCE&G, GENCO and Fuel Company. The equity interests in GENCO and Fuel Company are held solely by SCANA, SCE&G’s parent. As a result, GENCO’s and Fuel Company’s equity and results of operations are reflected as noncontrolling interest in Consolidated SCE&G’s condensed consolidated financial statements. GENCO owns a coal-fired electric generating station with a 605 MW net generating capacity (summer rating). GENCO’s electricity is sold, pursuant to a FERC-approved tariff, solely to SCE&G under the terms of a power purchase agreement and related operating agreement. The effects of these transactions are eliminated in consolidation. Substantially all of GENCO’s property (carrying value of approximately $483 million ) serves as collateral for its long-term borrowings. Fuel Company acquires, owns and provides financing for SCE&G’s nuclear fuel, certain fossil fuels and emission and other environmental allowances. See also Note 4. Income Statement Presentation Revenues and expenses arising from regulated businesses and, in the case of the Company, retail natural gas marketing businesses (including those activities of segments described in Note 10) are presented within Operating Income, and all other activities are presented within Other Income (Expense). Consistent with this presentation, the Company presents the 2015 gain on the sale of CGT within Operating Income and the 2015 gain on the sale of SCI within Other Income (Expense). Asset Management and Supply Service Agreement PSNC Energy, a subsidiary of SCANA, utilizes an asset management and supply service agreement with a counterparty for certain natural gas storage facilities. Such counterparty held, through an agency relationship, 41% and 46% of PSNC Energy’s natural gas inventory at September 30, 2016 and December 31, 2015, respectively, with a carrying value of $13.1 million and $17.7 million , respectively. Under the terms of the asset management agreement, PSNC Energy receives storage asset management fees of which 75% are credited to rate payers. No fees are received under the supply service agreement. This agreement expires on March 31, 2017. Earnings Per Share The Company computes basic earnings per share by dividing net income by the weighted average number of common shares outstanding for the period. When applicable, the Company computes diluted earnings per share using this same formula, after giving effect to securities considered to be dilutive potential common stock utilizing the treasury stock method. Dispositions In the first quarter of 2015, SCANA sold CGT and SCI. CGT was an interstate natural gas pipeline regulated by FERC that transported natural gas in South Carolina and southeastern Georgia, and it was sold to Dominion Resources, Inc. SCI provided fiber optic communications and other services and built, managed and leased communications towers in several southeastern states, and it was sold to a subsidiary of Spirit Communications. These sales resulted in recognition of pre-tax gains totaling approximately $342 million . As previously noted, the pre-tax gain from the sale of CGT is included within Operating Income and the pre-tax gain from the sale of SCI is included within Other Income (Expense) on the Company's condensed consolidated statement of income. CGT and SCI operated principally in wholesale markets, whereas the Company's primary focus is the delivery of energy-related products and services to retail markets. In addition, neither CGT nor SCI met accounting criteria for disclosure as a reportable segment and were included within the All Other caption in Note 10. The sales of CGT and SCI did not represent a strategic shift that had a major effect on the Company's operations; therefore, these sales did not meet the criteria for classification as discontinued operations. Reclassifications Certain prior period amounts within the reconciliations of Net income to Net Cash Provided From Operating Activities on the Condensed Consolidated Statements of Cash Flows of the Company and Consolidated SCE&G have been reclassified to conform to the current period presentation. Specifically, $(100) million of non-cash changes in fair value of interest rate swaps has been reclassified from the changes in Derivative financial instruments caption (which for Consolidated SCE&G resulted in the caption being eliminated) with offsetting reclassifications of $66 million from the changes in Regulatory assets caption, $(5) million from the changes in Regulatory liabilities caption, $(6) million from the changes in Other assets caption and $45 million from the changes in Other liabilities caption. Additionally, due to insignificance, the captions for changes in Interest accrued and changes in Pension and other postretirement benefits which were utilized in the reconciliation for the prior period have been eliminated and their amounts included within changes in Other liabilities, and the caption of Losses from equity method investments has been eliminated and its amount included within changes in Other assets. These reclassifications had no effect on Net Cash Provided From Operating Activities or on any other subtotal in the Condensed Consolidated Statements of Cash Flows. New Accounting Matters In May 2014, the FASB issued accounting guidance for revenue arising from contracts with customers that supersedes most earlier revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized, and will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2018. The guidance permits adoption using a retrospective method, with options to elect certain practical expedients, or recognition of a cumulative effect in the year of initial adoption. The Company and Consolidated SCE&G have not determined which method of adoption will be employed or what practical expedients may be elected. The Company and Consolidated SCE&G have not determined the impact this guidance will have on their respective financial statements. However, the identification of implementation project team members and the analysis of contracts with customers to which the guidance might be applicable, particularly large customer contracts, have begun. In July 2015, the FASB issued accounting guidance intended to simplify the subsequent measurement of inventory cost by requiring most inventory to be measured at the lower of cost and net realizable value. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2017 and have determined that the adoption of this guidance will not have a significant impact on their respective financial statements. In January 2016, the FASB issued accounting guidance that will change how entities measure certain equity investments and financial liabilities, among other things. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2018. The Company and Consolidated SCE&G are evaluating this guidance and do not anticipate that its adoption will have a significant impact on their respective financial statements. In February 2016, the FASB issued accounting guidance related to the recognition, measurement and presentation of leases. The guidance applies a right-of-use model and, for lessees, requires all leases with a duration over 12 months to be recorded on the balance sheet, with the rights of use treated as assets and the payment obligations treated as liabilities. Further, and without consideration of any regulatory accounting requirements which may apply, depending primarily on the nature of the assets and the relative consumption of them, lease costs will be recognized either through the separate amortization of the right-of-use asset and the recognition of the interest cost related to the payment obligation, or through the recording of a combined straight-line rental expense. For lessors, the guidance calls for the recognition of income either through the derecognition of assets and subsequent recording of interest income on lease amounts receivable, or through the recognition of rental income on a straight-line basis, also depending on the nature of the assets and relative consumption. The guidance will be effective for years beginning in 2019. The Company and Consolidated SCE&G have not determined what impact this guidance will have on their respective financial statements. However, the identification of implementation project team members and the initial identification and analysis of leasing and related contracts to which the guidance might be applicable have begun. In March 2016, the FASB issued accounting guidance changing how companies account for certain aspects of share-based payments to employees. Entities will be required to recognize the income tax effects of awards in the income statement when the awards vest or are settled. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2017. The Company and Consolidated SCE&G are evaluating this guidance and, based on the nature of their current share-based awards practices, do not anticipate that its adoption will have a significant impact on their respective financial statements. In June 2016, the FASB issued accounting guidance requiring the use of a current expected credit loss impairment model for certain financial instruments. The new model is applicable to trade receivables and most debt instruments, among other financial instruments, and is intended to result in impairment losses being recognized earlier than under current guidance. The Company and Consolidated SCE&G must adopt this guidance beginning in 2020, including interim periods, though the guidance may be adopted in 2019. The Company and Consolidated SCE&G have not determined when this guidance will be adopted or what impact it will have on their respective financial statements. In August 2016, the FASB issued accounting guidance to reduce diversity in cash flow classification related to certain transactions. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2018 and do not anticipate that its adoption will impact their respective financial statements. |

RATE AND OTHER REGULATORY MATTE
RATE AND OTHER REGULATORY MATTERS | 9 Months Ended |

Rate Matters [Line Items] | |
Public Utilities Disclosure [Text Block] | RATE AND OTHER REGULATORY MATTERS Rate Matters Electric - Cost of Fuel By order dated July 15, 2015, the SCPSC approved a settlement agreement among SCE&G, ORS and certain other parties concerning SCE&G's petition for approval to participate in a DER program and to recover DER program costs as a separate component of SCE&G's overall fuel factor. Under this order, SCE&G will, among other things, implement programs to encourage the development of renewable energy facilities with a total nameplate capacity of at least approximately 84.5 MW by the end of 2020, of which half is to be customer-scale solar capacity and half is to be utility-scale solar capacity. By order dated April 29, 2016, the SCPSC approved a settlement agreement among SCE&G, ORS and certain other parties to decrease the total fuel cost component of retail electric rates. SCE&G reduced the total fuel cost component of retail electric rates to reflect lower projected fuel costs and to eliminate over-collected balances of approximately $61 million for base fuel and environmental costs over a 12-month period beginning with the first billing cycle of May 2016. SCE&G also began to recover projected DER program costs of approximately $6.9 million beginning with the first billing cycle of May 2016. Electric - Base Rates Pursuant to an SCPSC order, SCE&G removes from rate base certain deferred income tax assets arising from capital expenditures related to the New Units and accrues carrying costs on those amounts during periods in which they are not included in rate base. Such carrying costs are determined at SCE&G’s weighted average long-term debt borrowing rate and are recorded as a regulatory asset and other income. Carrying costs during the three and nine months ended September 30, 2016 totaled $3.5 million and $10.0 million , respectively. During the three and nine months ended September 30, 2015, carrying costs totaled $2.4 million and $6.5 million , respectively. SCE&G anticipates that when the New Units are placed in service and accelerated tax depreciation is recognized on them, these deferred income tax assets will decline. When these deferred income tax assets are fully offset by related deferred income tax liabilities, the carrying cost accruals will cease, and the regulatory asset will begin to be amortized. By order dated April 29, 2016, the SCPSC approved SCE&G’s request to increase its pension costs rider. Under the terms of the order, SCE&G may request an annual adjustment to the pension rider. The increased pension rider is designed to allow SCE&G to recover projected pension costs, including under-collections, over a 12-month period, beginning with the first billing cycle in May 2016. In April 2016, ORS filed a report arising from its review of SCE&G’s annual DSM Programs rate rider filing. ORS concluded the updated DSM Programs rider proposal was developed in accordance with terms and conditions approved by the SCPSC in prior orders and recommended that SCE&G's request be approved. By Order dated April 29, 2016, the SCPSC accepted ORS's recommendations and approved SCE&G's request to recover $37.6 million of costs and net lost revenues along with a shared savings incentive associated with the DSM Programs. Electric - BLRA On May 26, 2016, SCE&G petitioned the SCPSC seeking approval to update the capital cost schedule and construction milestone schedule for the New Units consistent with the October 2015 Amendment. Within this petition, SCE&G also informed the SCPSC that it had notified WEC of its intent to elect the fixed price option, subject to concurrence by Santee Cooper and approval by the SCPSC. The petition reflects an increase in total project costs of approximately $852 million over the cost approved by the SCPSC in September 2015, of which approximately $505 million is directly attributable to the fixed price option. On July 1, 2016, SCE&G reduced the total project cost amount set forth in its petition to $846 million . SCE&G's estimated gross construction cost for the project is now estimated to be approximately $7.7 billion , including owner’s costs, transmission, escalation and AFC. SCE&G executed the fixed price option on July 1, 2016, for itself and on behalf of Santee Cooper, subject to SCPSC approval. On September 1, 2016, SCE&G, ORS and certain other parties entered into a settlement agreement related to SCE&G’s May 26, 2016 petition to update construction and capital cost schedules, including SCE&G’s election of the fixed price option included in the October 2015 Amendment. Under the terms of the settlement agreement, the settling parties agree to support SCPSC approval of the updated construction schedule, which indicates substantial completion dates of August 2019 and August 2020 for the New Units, and SCE&G’s election of the fixed price option. In addition, the settling parties agree to the inclusion of an additional $831 million in the capital cost schedule and to revise the allowed ROE for the New Units from 10.50% to 10.25%. The revised ROE will be applied prospectively for the purpose of calculating revised rates sought by SCE&G under the BLRA on and after January 1, 2017, until such time as the New Units are completed. Also, pursuant to the settlement agreement, SCE&G agreed not to file any future requests to amend its capital cost schedule prior to January 28, 2019. For those capital costs which were included in the total project amount set forth in SCE&G’s petition but not included in the capital cost schedule as agreed upon by the settling parties, SCE&G may seek to include those costs in its calculation of revised rates after January 2019. The settlement agreement is subject to SCPSC approval. A public hearing on this matter was held in October 2016, and the SCPSC is expected to issue its order in November 2016. See also Note 9. On October 19, 2016, the SCPSC approved an increase of approximately $64.4 million , or 2.7% , in SCE&G's retail electric rates under provisions of the BLRA. The rate increase is effective for the first billing cycle on or after November 27, 2016. Gas - SCE&G By order dated October 13, 2016, the SCPSC approved SCE&G's quarterly monitoring report for the 12-month period ended March 31, 2016, and an approximately $4.1 million , or 1.2% , overall increase to its natural gas rates under the terms of the RSA. The rate adjustment will be effective for the first billing cycle in November 2016. SCE&G's natural gas tariffs include a PGA that provides for the recovery of actual gas costs incurred, including transportation costs. SCE&G's gas rates are calculated using a methodology which may adjust the cost of gas monthly based on a 12-month rolling average , and its gas purchasing policies and practices are reviewed annually by the SCPSC. SCE&G's annual PGA hearing for the 12-month period ending July 31, 2016, was held on November 3, 2016, and the SCPSC's decision is pending. Gas - PSNC Energy On October 28, 2016, the NCUC granted PSNC Energy a net annual increase of approximately $19.1 million , or 4.39% , in rates and charges to customers, and set PSNC Energy's authorized ROE at 9.7% . The rate increase is largely associated with recovering costs related to expanding and operating PSNC Energy's pipeline system. In addition, PSNC Energy was authorized to implement a tracker that provides for biannual rate adjustments in order to recover the revenue requirement associated with integrity management plant investment and associated costs incurred by PSNC Energy resulting from prevailing federal standards for pipeline integrity and safety that are not otherwise included in current base rates. The new rates are effective for services rendered on or after November 1, 2016. Regulatory Assets and Regulatory Liabilities Rate-regulated utilities recognize in their financial statements certain revenues and expenses in different periods than do other enterprises. As a result, the Company and Consolidated SCE&G have recorded regulatory assets and regulatory liabilities which are summarized in the following tables. Other than unrecovered plant, substantially all regulatory assets are either explicitly excluded from rate base or are effectively excluded from rate base due to their being offset by related liabilities. The Company Consolidated SCE&G Millions of dollars September 30, December 31, September 30, December 31, Regulatory Assets: Accumulated deferred income taxes $ 301 $ 298 $ 294 $ 291 Environmental remediation costs 33 42 26 35 AROs and related funding 402 405 380 384 Deferred employee benefit plan costs 311 325 282 295 Deferred losses on interest rate derivatives 791 535 791 535 Unrecovered plant 119 127 119 127 DSM Programs 58 61 58 61 Deferred costs related to uncertain tax position 14 — 14 — Other 173 144 150 129 Total Regulatory Assets $ 2,202 $ 1,937 $ 2,114 $ 1,857 Regulatory Liabilities: Asset removal costs $ 756 $ 732 $ 533 $ 519 Deferred gains on interest rate derivatives 80 96 80 96 Other 28 27 17 20 Total Regulatory Liabilities $ 864 $ 855 $ 630 $ 635 Accumulated deferred income tax liabilities that arise from utility operations that have not been included in customer rates are recorded as a regulatory asset. A substantial portion of these regulatory assets relate to depreciation and are expected to be recovered over the remaining lives of the related property which may range up to approximately 85 years. Similarly, accumulated deferred income tax assets arising from deferred investment tax credits are recorded as a regulatory liability. Environmental remediation costs represent costs associated with the assessment and clean-up of sites currently or formerly owned by the Company or Consolidated SCE&G, and are expected to be recovered over periods of up to approximately 18 years. AROs and related funding represents the regulatory asset associated with the legal obligation to decommission and dismantle Summer Station and conditional AROs related to generation, transmission and distribution properties, including gas pipelines. These regulatory assets are expected to be recovered over the related property lives and periods of decommissioning which may range up to approximately 110 years. Employee benefit plan costs of the regulated utilities have historically been recovered as they have been recorded under GAAP. Deferred employee benefit plan costs represent amounts of pension and other postretirement benefit costs which were accrued as liabilities and treated as regulatory assets pursuant to FERC guidance, and costs deferred pursuant to specific SCPSC regulatory orders. In 2013 SCE&G began recovering through utility rates approximately $63 million of deferred pension costs for electric operations over approximately 30 years and approximately $14 million of deferred pension costs for gas operations over approximately 14 years. The remainder of the deferred benefit costs are expected to be recovered through utility rates, primarily over average service periods of participating employees, or up to approximately 12 years. Deferred losses or gains on interest rate derivatives represent (i) the effective portions of changes in fair value and payments made or received upon settlement of certain interest rate derivatives designated as cash flow hedges and (ii) the changes in fair value and payments made or received upon settlement of certain other interest rate derivatives not so designated. The amounts recorded with respect to (i) are expected to be amortized to interest expense over the lives of the underlying debt through 2043. The amounts recorded with respect to (ii) are expected to be similarly amortized to interest expense through 2065 except when, in the case of deferred gains, such amounts are applied otherwise at the direction of the SCPSC. Unrecovered plant represents the carrying value of coal-fired generating units, including related materials and supplies inventory, retired from service prior to being fully depreciated. Pursuant to SCPSC approval, SCE&G will amortize these amounts through cost of service rates over the units' previous estimated remaining useful lives through approximately 2025. Unamortized amounts are included in rate base and are earning a current return. DSM Programs represent SCE&G's deferred costs associated with such programs, and such deferred costs are currently being recovered over approximately five years through an approved rate rider. Deferred costs related to uncertain tax position primarily represent the estimated amounts of domestic production activities deductions foregone as a result of the Company’s deduction of certain research and experimentation expenditures for income tax purposes, net of related tax credits, as well as accrued interest expense and other costs arising from this unrecognized tax benefit. SCE&G's current customer rates reflect the availability of domestic production activities deductions. These net deferred costs are expected to be recovered through utility rates following ultimate resolution of the claims. See also Note 5. Various other regulatory assets are expected to be recovered in rates over periods of up to approximately 30 years. Asset removal costs represent estimated net collections through depreciation rates of amounts to be incurred for the removal of assets in the future. The SCPSC, the NCUC or the FERC has reviewed and approved through specific orders most of the items shown as regulatory assets. Other regulatory assets include, but are not limited to, certain costs which have not been specifically approved for recovery by the SCPSC, the NCUC or by the FERC. In recording such costs as regulatory assets, management believes the costs will be allowable under existing rate-making concepts that are embodied in rate orders. The costs are currently not being recovered, but are expected to be recovered through rates in future periods. In the future, as a result of deregulation or other changes in the regulatory environment or changes in accounting requirements, the Company or Consolidated SCE&G could be required to write off its regulatory assets and liabilities. Such an event could have a material effect on the Company's and Consolidated SCE&G's financial statements in the period the write-off would be recorded. |

Rate Matters [Line Items] | |
Public Utilities Disclosure [Text Block] | RATE AND OTHER REGULATORY MATTERS Rate Matters Electric - Cost of Fuel By order dated July 15, 2015, the SCPSC approved a settlement agreement among SCE&G, ORS and certain other parties concerning SCE&G's petition for approval to participate in a DER program and to recover DER program costs as a separate component of SCE&G's overall fuel factor. Under this order, SCE&G will, among other things, implement programs to encourage the development of renewable energy facilities with a total nameplate capacity of at least approximately 84.5 MW by the end of 2020, of which half is to be customer-scale solar capacity and half is to be utility-scale solar capacity. By order dated April 29, 2016, the SCPSC approved a settlement agreement among SCE&G, ORS and certain other parties to decrease the total fuel cost component of retail electric rates. SCE&G reduced the total fuel cost component of retail electric rates to reflect lower projected fuel costs and to eliminate over-collected balances of approximately $61 million for base fuel and environmental costs over a 12-month period beginning with the first billing cycle of May 2016. SCE&G also began to recover projected DER program costs of approximately $6.9 million beginning with the first billing cycle of May 2016. Electric - Base Rates Pursuant to an SCPSC order, SCE&G removes from rate base certain deferred income tax assets arising from capital expenditures related to the New Units and accrues carrying costs on those amounts during periods in which they are not included in rate base. Such carrying costs are determined at SCE&G’s weighted average long-term debt borrowing rate and are recorded as a regulatory asset and other income. Carrying costs during the three and nine months ended September 30, 2016 totaled $3.5 million and $10.0 million , respectively. During the three and nine months ended September 30, 2015, carrying costs totaled $2.4 million and $6.5 million , respectively. SCE&G anticipates that when the New Units are placed in service and accelerated tax depreciation is recognized on them, these deferred income tax assets will decline. When these deferred income tax assets are fully offset by related deferred income tax liabilities, the carrying cost accruals will cease, and the regulatory asset will begin to be amortized. By order dated April 29, 2016, the SCPSC approved SCE&G’s request to increase its pension costs rider. Under the terms of the order, SCE&G may request an annual adjustment to the pension rider. The increased pension rider is designed to allow SCE&G to recover projected pension costs, including under-collections, over a 12-month period, beginning with the first billing cycle in May 2016. In April 2016, ORS filed a report arising from its review of SCE&G’s annual DSM Programs rate rider filing. ORS concluded the updated DSM Programs rider proposal was developed in accordance with terms and conditions approved by the SCPSC in prior orders and recommended that SCE&G's request be approved. By Order dated April 29, 2016, the SCPSC accepted ORS's recommendations and approved SCE&G's request to recover $37.6 million of costs and net lost revenues along with a shared savings incentive associated with the DSM Programs. Electric - BLRA On May 26, 2016, SCE&G petitioned the SCPSC seeking approval to update the capital cost schedule and construction milestone schedule for the New Units consistent with the October 2015 Amendment. Within this petition, SCE&G also informed the SCPSC that it had notified WEC of its intent to elect the fixed price option, subject to concurrence by Santee Cooper and approval by the SCPSC. The petition reflects an increase in total project costs of approximately $852 million over the cost approved by the SCPSC in September 2015, of which approximately $505 million is directly attributable to the fixed price option. On July 1, 2016, SCE&G reduced the total project cost amount set forth in its petition to $846 million . SCE&G's estimated gross construction cost for the project is now estimated to be approximately $7.7 billion , including owner’s costs, transmission, escalation and AFC. SCE&G executed the fixed price option on July 1, 2016, for itself and on behalf of Santee Cooper, subject to SCPSC approval. On September 1, 2016, SCE&G, ORS and certain other parties entered into a settlement agreement related to SCE&G’s May 26, 2016 petition to update construction and capital cost schedules, including SCE&G’s election of the fixed price option included in the October 2015 Amendment. Under the terms of the settlement agreement, the settling parties agree to support SCPSC approval of the updated construction schedule, which indicates substantial completion dates of August 2019 and August 2020 for the New Units, and SCE&G’s election of the fixed price option. In addition, the settling parties agree to the inclusion of an additional $831 million in the capital cost schedule and to revise the allowed ROE for the New Units from 10.50% to 10.25%. The revised ROE will be applied prospectively for the purpose of calculating revised rates sought by SCE&G under the BLRA on and after January 1, 2017, until such time as the New Units are completed. Also, pursuant to the settlement agreement, SCE&G agreed not to file any future requests to amend its capital cost schedule prior to January 28, 2019. For those capital costs which were included in the total project amount set forth in SCE&G’s petition but not included in the capital cost schedule as agreed upon by the settling parties, SCE&G may seek to include those costs in its calculation of revised rates after January 2019. The settlement agreement is subject to SCPSC approval. A public hearing on this matter was held in October 2016, and the SCPSC is expected to issue its order in November 2016. See also Note 9. On October 19, 2016, the SCPSC approved an increase of approximately $64.4 million , or 2.7% , in SCE&G's retail electric rates under provisions of the BLRA. The rate increase is effective for the first billing cycle on or after November 27, 2016. Gas - SCE&G By order dated October 13, 2016, the SCPSC approved SCE&G's quarterly monitoring report for the 12-month period ended March 31, 2016, and an approximately $4.1 million , or 1.2% , overall increase to its natural gas rates under the terms of the RSA. The rate adjustment will be effective for the first billing cycle in November 2016. SCE&G's natural gas tariffs include a PGA that provides for the recovery of actual gas costs incurred, including transportation costs. SCE&G's gas rates are calculated using a methodology which may adjust the cost of gas monthly based on a 12-month rolling average , and its gas purchasing policies and practices are reviewed annually by the SCPSC. SCE&G's annual PGA hearing for the 12-month period ending July 31, 2016, was held on November 3, 2016, and the SCPSC's decision is pending. Gas - PSNC Energy On October 28, 2016, the NCUC granted PSNC Energy a net annual increase of approximately $19.1 million , or 4.39% , in rates and charges to customers, and set PSNC Energy's authorized ROE at 9.7% . The rate increase is largely associated with recovering costs related to expanding and operating PSNC Energy's pipeline system. In addition, PSNC Energy was authorized to implement a tracker that provides for biannual rate adjustments in order to recover the revenue requirement associated with integrity management plant investment and associated costs incurred by PSNC Energy resulting from prevailing federal standards for pipeline integrity and safety that are not otherwise included in current base rates. The new rates are effective for services rendered on or after November 1, 2016. Regulatory Assets and Regulatory Liabilities Rate-regulated utilities recognize in their financial statements certain revenues and expenses in different periods than do other enterprises. As a result, the Company and Consolidated SCE&G have recorded regulatory assets and regulatory liabilities which are summarized in the following tables. Other than unrecovered plant, substantially all regulatory assets are either explicitly excluded from rate base or are effectively excluded from rate base due to their being offset by related liabilities.

Income Tax Disclosure [Text Block] | INCOME TAXES Consolidated SCE&G is included in the consolidated federal income tax returns of SCANA and files various applicable state and local income tax returns. During 2013 and 2014, SCANA amended certain of its income tax returns to claim certain tax-defined research and experimentation deductions and credits and to reflect related impacts on other items such as domestic production activities deductions. SCANA also made similar claims in filing its original 2013 and 2014 returns in 2014 and 2015, respectively. In September 2016, SCANA claimed significant research and experimentation deductions and credits (offset by reductions in its domestic production activities deductions), related to the ongoing design and construction activities of the New Units, in its 2015 income tax returns. These claims followed the issuance of final IRS regulations in 2014 regarding such treatment with respect to expenditures related to the design and construction of pilot models. The IRS examined the claims in the amended returns, and as such examination of claims progressed without resolution, the Company and Consolidated SCE&G evaluated and recorded adjustments to unrecognized tax benefits; however, none of these changes materially affected the Company's and Consolidated SCE&G's effective tax rate. In October 2016, the examination of the amended tax returns progressed to appeals. In addition, the IRS has begun an examination of SCANA's 2013 through 2015 income tax returns. These income tax deductions and credits are considered to be uncertain tax positions, and under relevant accounting guidance, estimates of the amounts of related tax benefits which may not be sustained upon examination by the taxing authorities are required to be recorded as unrecognized tax benefits in the financial statements. In connection with all of these federal and related state filings, the Company and Consolidated SCE&G have recorded an unrecognized tax benefit of $276 million ( $254 million , net of the impact of the state deduction on the federal return). If recognized, $17 million of the tax benefit would affect the Company’s and Consolidated SCE&G's effective tax rate (see discussion below regarding deferral of benefits related to 2015 forward). It is reasonably possible that these unrecognized tax benefits may increase by an additional $228 million within the next 12 months as additional expenditures giving rise to tax benefits are incurred. It is also reasonably possible that these unrecognized tax benefits may decrease by $49 million within the next 12 months if the claims on amended returns which are currently in appeals are resolved. No other material changes in the status of the Company’s or Consolidated SCE&G's tax positions have occurred through September 30, 2016. In connection with the research and experimentation deduction and credit claims reflected on the 2015 income tax returns and the expectation of similar claims to be made in determining 2016’s taxable income, the Company and Consolidated SCE&G have recorded regulatory assets for estimated foregone domestic production activities deductions, offset by estimated credits, and expect that such (net) deferred costs, along with any interest (see below) and other related deferred costs, will be recoverable through customer rates in future years. SCE&G's current customer rates reflect the availability of domestic production activities deductions (see Note 2). Estimated interest expense accrued with respect to the unrecognized tax benefits related to the research and experimentation deductions in the 2015 income tax returns has been deferred as a regulatory asset and is expected to be recoverable through customer rates in future years. See also Note 2. Otherwise, the Company and Consolidated SCE&G recognize interest accrued related to unrecognized tax benefits within interest expense or interest income and recognize tax penalties within other expenses. Amounts recorded for such interest income, interest expense or tax penalties have not been material. On August 2, 2016, the State of North Carolina announced the lowering of its corporate income tax rate from 4% to 3% effective January 1, 2017. This reduction did not have a material impact on the Company's financial position, results of operations or cash flows. |

Income Tax Disclosure [Text Block] | INCOME TAXES Consolidated SCE&G is included in the consolidated federal income tax returns of SCANA and files various applicable state and local income tax returns. During 2013 and 2014, SCANA amended certain of its income tax returns to claim certain tax-defined research and experimentation deductions and credits and to reflect related impacts on other items such as domestic production activities deductions. SCANA also made similar claims in filing its original 2013 and 2014 returns in 2014 and 2015, respectively. In September 2016, SCANA claimed significant research and experimentation deductions and credits (offset by reductions in its domestic production activities deductions), related to the ongoing design and construction activities of the New Units, in its 2015 income tax returns. These claims followed the issuance of final IRS regulations in 2014 regarding such treatment with respect to expenditures related to the design and construction of pilot models. The IRS examined the claims in the amended returns, and as such examination of claims progressed without resolution, the Company and Consolidated SCE&G evaluated and recorded adjustments to unrecognized tax benefits; however, none of these changes materially affected the Company's and Consolidated SCE&G's effective tax rate. In October 2016, the examination of the amended tax returns progressed to appeals. In addition, the IRS has begun an examination of SCANA's 2013 through 2015 income tax returns. These income tax deductions and credits are considered to be uncertain tax positions, and under relevant accounting guidance, estimates of the amounts of related tax benefits which may not be sustained upon examination by the taxing authorities are required to be recorded as unrecognized tax benefits in the financial statements. In connection with all of these federal and related state filings, the Company and Consolidated SCE&G have recorded an unrecognized tax benefit of $276 million ( $254 million , net of the impact of the state deduction on the federal return). If recognized, $17 million of the tax benefit would affect the Company’s and Consolidated SCE&G's effective tax rate (see discussion below regarding deferral of benefits related to 2015 forward). It is reasonably possible that these unrecognized tax benefits may increase by an additional $228 million within the next 12 months as additional expenditures giving rise to tax benefits are incurred. It is also reasonably possible that these unrecognized tax benefits may decrease by $49 million within the next 12 months if the claims on amended returns which are currently in appeals are resolved. No other material changes in the status of the Company’s or Consolidated SCE&G's tax positions have occurred through September 30, 2016.

Derivative Instruments and Hedging Activities Disclosure [Text Block] | 6. DERIVATIVE FINANCIAL INSTRUMENTS Derivative instruments are recognized either as assets or liabilities in the statement of financial position and are measured at fair value. Changes in the fair value of derivative instruments are recognized either in earnings, as a component of other comprehensive income (loss) or, for regulated operations, within regulatory assets or regulatory liabilities, depending upon the intended use of the derivative and the resulting designation. Policies and procedures and risk limits are established to control the level of market, credit, liquidity and operational and administrative risks. SCANA’s Board of Directors has delegated to a Risk Management Committee the authority to set risk limits, establish policies and procedures for risk management and measurement, and oversee and review the risk management process and infrastructure for SCANA and each of its subsidiaries. The Risk Management Committee, which is comprised of certain officers, including the Risk Management Officer and other senior officers, apprises the Audit Committee of the Board of Directors with regard to the management of risk and brings to their attention significant areas of concern. Written policies define the physical and financial transactions that are approved, as well as the authorization requirements and limits for transactions. Commodity Derivatives The Company uses derivative instruments to hedge forward purchases and sales of natural gas, which create market risks of different types. Instruments designated as cash flow hedges are used to hedge risks associated with fixed price obligations in a volatile market and risks associated with price differentials at different delivery locations. Instruments designated as fair value hedges are used to mitigate exposure to fluctuating market prices created by fixed prices of stored natural gas. The basic types of financial instruments utilized are exchange-traded instruments, such as NYMEX futures contracts or options, and over-the-counter instruments such as options and swaps, which are typically offered by energy companies and financial institutions. Cash settlements of commodity derivatives are classified as operating activities in the condensed consolidated statements of cash flows. PSNC Energy hedges natural gas purchasing activities using over-the-counter options and NYMEX futures and options. PSNC Energy’s tariffs include a provision for the recovery of actual gas costs incurred, including any costs of hedging. PSNC Energy records premiums, transaction fees, margin requirements and any realized gains or losses from its hedging program in deferred accounts as a regulatory asset or liability for the under- or over-recovery of gas costs. These derivative financial instruments are not designated as hedges for accounting purposes. Unrealized gains and losses on qualifying cash flow hedges of nonregulated operations are deferred in AOCI. When the hedged transactions affect earnings, previously recorded gains and losses are reclassified from AOCI to cost of gas. The effects of gains or losses resulting from these hedging activities are either offset by the recording of the related hedged transactions or are included in gas sales pricing decisions made by the business unit. As an accommodation to certain customers, SEMI, as part of its energy management services, offers fixed price supply contracts which are accounted for as derivatives. These sales contracts are offset by the purchase of supply futures and swaps which are also accounted for as derivatives. Neither the sales contracts nor the related supply futures and swaps are designated as hedges for accounting purposes. Interest Rate Swaps Interest rate swaps may be used to manage interest rate risk and exposure to changes in fair value attributable to changes in interest rates on certain debt issuances. In cases in which swaps designated as cash flow hedges are used to synthetically convert variable rate debt to fixed rate debt, periodic payments to or receipts from swap counterparties related to these derivatives are recorded within interest expense. Forward starting swap agreements that are designated as cash flow hedges may be used in anticipation of the issuance of debt. Except as described in the following paragraph, the effective portions of changes in fair value and payments made or received upon termination of such agreements for regulated subsidiaries are recorded in regulatory assets or regulatory liabilities. For SCANA and the nonregulated subsidiaries, such amounts are recorded in AOCI. Such amounts are amortized to interest expense over the term of the underlying debt. Ineffective portions of fair value changes are recognized in income. Pursuant to regulatory orders, interest rate derivatives entered into by SCE&G after October 2013 are not designated as cash flow hedges and fair value changes and settlement amounts related to them are recorded as regulatory assets and liabilities. Settlement losses on swaps will be amortized over the lives of subsequent debt issuances and gains may be applied to under-collected fuel, may be amortized to interest expense or may be applied as otherwise directed by the SCPSC. Cash payments made or received upon termination of these financial instruments are classified as investing activities for cash flow statement purposes.

Statement [Line Items] | |
Commitments and Contingencies Disclosure [Text Block] | COMMITMENTS AND CONTINGENCIES Nuclear Insurance Under Price-Anderson, SCE&G (for itself and on behalf of Santee Cooper, a one-third owner of Summer Station Unit 1) maintains agreements of indemnity with the NRC that, together with private insurance, cover third-party liability arising from any nuclear incident occurring at SCE&G's nuclear power plant. Price-Anderson provides funds up to $13.4 billion for public liability claims that could arise from a single nuclear incident. Each nuclear plant is insured against this liability to a maximum of $375 million by ANI with the remaining coverage provided by a mandatory program of deferred premiums that could be assessed, after a nuclear incident, against all owners of commercial nuclear reactors. Each reactor licensee is currently liable for up to $127.3 million per reactor owned for each nuclear incident occurring at any reactor in the United States, provided that not more than $18.9 million of the liability per reactor would be assessed per year. SCE&G’s maximum assessment, based on its two-thirds ownership of Summer Station Unit 1, would be $84.8 million per incident, but not more than $12.6 million per year. Both the maximum assessment per reactor and the maximum yearly assessment are adjusted for inflation at least every five years. SCE&G currently maintains insurance policies (for itself and on behalf of Santee Cooper) with NEIL. The policies provide coverage to Summer Station Unit 1 for property damage and outage costs up to $2.75 billion resulting from an event of nuclear origin and up to $2.33 billion resulting from an event of a non-nuclear origin. In addition, a builder's risk insurance policy has been purchased from NEIL for the construction of the New Units. This policy provides the owners of the New Units up to $500 million of total coverage for accidental property damage occurring during construction. The NEIL policies, in the aggregate, are subject to a maximum loss of $2.75 billion for any single loss occurrence. All of the NEIL policies permit retrospective assessments under certain conditions to cover insurer’s losses. Based on the current annual premium, SCE&G’s portion of the retrospective premium assessment would not exceed $45.8 million . SCE&G currently maintains an excess property insurance policy (for itself and on behalf of Santee Cooper) with EMANI. The policy provides coverage to Summer Station Unit 1 for property damage and outage costs up to $415 million resulting from an event of a non-nuclear origin. The EMANI policy permits retrospective assessments under certain conditions to cover insurer's losses. Based on the current annual premium, SCE&G's portion of the retrospective premium assessment would not exceed $1.8 million . To the extent that insurable claims for property damage, decontamination, repair and replacement and other costs and expenses arising from an incident at Summer Station Unit 1 exceed the policy limits of insurance, or to the extent such insurance becomes unavailable in the future, and to the extent that SCE&G's rates would not recover the cost of any purchased replacement power, SCE&G will retain the risk of loss as a self-insurer. SCE&G has no reason to anticipate a serious nuclear or other incident. However, if such an incident were to occur, it likely would have a material impact on the Company’s and Consolidated SCE&G's results of operations, cash flows and financial position. New Nuclear Construction In 2008, SCE&G, on behalf of itself and as agent for Santee Cooper, contracted with the Consortium for the design and construction of the New Units at the site of Summer Station. SCE&G's current ownership share in the New Units is 55% . As discussed below, SCE&G has agreed to acquire an additional 5% ownership in the New Units from Santee Cooper. EPC Contract and BLRA Matters The construction of the New Units and SCE&G’s related recovery of financing costs through rates is subject to review and approval by the SCPSC as provided for in the BLRA. Under the BLRA, the SCPSC has approved, among other things, a milestone schedule and a capital costs estimates schedule for the New Units. This approval constitutes a final and binding determination that the New Units are used and useful for utility purposes, and that the capital costs associated with the New Units are prudent utility costs and expenses and are properly included in rates, so long as the New Units are constructed or are being constructed within the parameters of the approved milestone schedule, including specified contingencies, and the approved capital costs estimates schedule. Subject to the same conditions, the BLRA provides that SCE&G may apply to the SCPSC annually for an order to recover through revised rates SCE&G’s weighted average cost of capital applied to all or part of the outstanding balance of construction work in progress concerning the New Units. As of September 30, 2016, SCE&G’s investment in the New Units, including related transmission, totaled $4.2 billion , for which the financing costs on $3.2 billion have been reflected in rates under the BLRA. The SCPSC granted initial approval of the construction schedule and related forecasted capital costs in 2009. The NRC issued COLs in March 2012. In November 2012, the SCPSC approved an updated milestone schedule and additional updated capital costs for the New Units. In addition, the SCPSC approved revised substantial completion dates for the New Units based on that March 2012 issuance of the COL and the amounts agreed upon by SCE&G and the Consortium in July 2012 to resolve known claims by the Consortium for costs related to COL delays, design modifications of the shield building and certain prefabricated structural modules for the New Units and unanticipated rock conditions at the site. In October 2014, the South Carolina Supreme Court affirmed the SCPSC's order on appeal. Since the settlement of delay-related claims in 2012, the Consortium has continued to experience delays in the schedule. Shield building construction remains a principal focus area for SCE&G’s oversight of the project. The primary critical path for Unit 2 and Unit 3 runs through the reinforced concrete activities necessary to support placement of shield building panels and the completion of shield building construction. WEC has reached agreement on a mitigation plan to accelerate shield building panel fabrication with one of its subcontractors. Additional mitigation will be required in the critical path to support the updated substantial completion dates described below. During the fourth quarter of 2013, the Consortium began a full re-baselining of the Unit 2 and Unit 3 construction schedules to incorporate a more detailed evaluation of the engineering and procurement activities necessary to accomplish the schedules and to provide a detailed reassessment of the impact of the revised Unit 2 and Unit 3 schedules on engineering and design resource allocations, procurement, construction work crew efficiencies and other items. The result was a revised fully integrated project schedule with timing of specific construction activities (Revised, Fully-Integrated Construction Schedule) along with related cost information. The Revised, Fully-Integrated Construction Schedule initially indicated that the substantial completion of Unit 2 was expected to occur in June 2019 and that the substantial completion of Unit 3 was expected to be approximately 12 months later. However, the Consortium continued to refine and update the Revised, Fully-Integrated Construction Schedule as certain designs were finalized, as construction progressed, and as additional information was received. See discussion of October 2015 Amendment below. In September 2015, the SCPSC approved an updated BLRA milestone schedule based on revised substantial completion dates for Units 2 and 3 of June 2019 and June 2020, respectively, each subject to an 18-month contingency period. In addition, the SCPSC approved certain updated owner's costs ( $245 million ) and other capital costs ( $453 million ), of which $539 million were associated with the schedule delays and other contested costs. In this proceeding, SCE&G's total projected capital costs (in 2007 dollars) and estimated gross construction cost (including escalation and AFC) were estimated to be $5.2 billion and $6.8 billion , respectively. These projections included amounts related to the Revised, Fully-Integrated Construction Schedule for which SCE&G had not accepted responsibility and which were the subject of dispute. As such, the updated milestone schedule and projections did not reflect the resolution of negotiations. In addition, the SCPSC approved a revision to the allowed return on equity for new nuclear construction from 11.0% to 10.5% . This revised return on equity was to be applied prospectively for the purpose of calculating revised rates sought by SCE&G under the BLRA on and after January 1, 2016, until such time as the New Units are completed. However, see discussion of May 2016 Petition and September 2016 Settlement Agreement below. October 2015 Amendment On October 27, 2015, SCE&G, Santee Cooper and the Consortium reached a settlement regarding the above mentioned disputes, and the EPC Contract was amended. The October 2015 Amendment became effective in December 2015, upon the consummation of the acquisition by WEC of the stock of Stone & Webster from CB&I. Following that acquisition, Stone & Webster continues to be a member of the Consortium as a subsidiary of WEC rather than CB&I, and WEC has engaged Fluor as a subcontracted construction manager. Among other things, the October 2015 Amendment: (i) resolved by settlement and release most outstanding disputes between SCE&G and the Consortium, in exchange for (a) an additional cost to be paid by SCE&G and Santee Cooper of $300 million (SCE&G’s 55% portion being $165 million ) and an increase in the fixed component of the contract price by that amount, and (b) a credit to SCE&G and Santee Cooper of $50 million (SCE&G’s 55% portion being approximately $27 million ) to be applied to the target component of the contract price, (ii) revised the guaranteed substantial completion dates of Units 2 and 3 to August 31, 2019 and 2020, respectively, (iii) revised the delay-related liquidated damages computation requirements, including those related to the eligibility of the New Units to earn Internal Revenue Code Section 45J production tax credits (see also below), and capped those aggregate liquidated damages at $463 million per New Unit (SCE&G’s 55% portion being approximately $255 million per New Unit), (iv) provided for payment to the Consortium of a completion bonus of $275 million per New Unit (SCE&G’s 55% portion being approximately $151 million per New Unit) for each New Unit placed in service by the deadline to qualify for production tax credits, (v) provided for development of a revised construction milestone payment schedule, with SCE&G and Santee Cooper making monthly payments of $100 million (SCE&G’s 55% portion being $55 million ) for each of the first five months following effectiveness, followed by payments made based on milestones achieved, (vi) provided that SCE&G and Santee Cooper waive and cancel the CB&I parent company guaranty with respect to the project, (vii) provided for an explicit definition of Change in Law designed to reduce the likelihood of certain future commercial disputes, with the Consortium also acknowledging and agreeing that the project scope includes providing New Units that meet the standards of the NRC approved Design Control Document Revision 19, (viii) established a DRB process for certain commercial claims and disputes, and (ix) eliminated the requirement or ability of any party to bring suit regarding disputes before substantial completion of the project. The DRB is comprised of three members chosen by the parties to resolve construction-related claims. Amounts in dispute of less than $5 million will be resolved by the DRB without recourse, and amounts in dispute greater than $5 million will be resolved by the DRB for the remainder of the construction of the New Units, with a reserved right to further arbitrate or to litigate such issues at the conclusion of construction. Under the October 2015 Amendment, SCE&G’s total estimated project costs increased over the $6.8 billion approved by the SCPSC in September 2015. In addition, SCE&G has updated project costs for estimated change orders related to certain outstanding disputes not resolved by the October 2015 Amendment. As a result, SCE&G's estimated gross construction cost for the project (including the effects of these change orders, escalation and AFC but excluding the fixed price option described below) totaled approximately $7.2 billion . The October 2015 Amendment also provided SCE&G and Santee Cooper an irrevocable option, until November 1, 2016 and subject to regulatory approvals, to further amend the EPC Contract to fix the total amount to be paid to the Consortium for its entire scope of work on the project (excluding a limited amount of work within the time and materials component of the contract price) after June 30, 2015 at $6.082 billion (SCE&G’s 55% portion being approximately $3.345 billion ). This total amount to be paid would be reduced by amounts paid since June 30, 2015. Under the fixed price option, the aggregate delay-related liquidated damages referred to in (iii) above would be capped at $338 million per New Unit (SCE&G’s 55% portion being approximately $186 million per New Unit), and the completion bonus referred to in (iv) above would be $150 million per New Unit (SCE&G’s 55% portion being approximately $83 million per New Unit). See information below regarding the execution of this fixed price option, subject to SCPSC approval. WEC has engaged Fluor to review and confirm the project schedule. The owners understand that this process has not been completed. The analysis by Fluor, to the extent that it is shared with the owners, could affect the owners’ expectations regarding the project schedule. In a discussion of the project status on September 26, 2016, and in response to SCE&G’s specific questioning regarding work crew efficiency and productivity and schedule mitigation efforts, WEC executive management stated that it had no reason to believe that the August 2019 and 2020 guaranteed completion dates would not be met. WEC submits monthly schedule updates, however, and it has reported that there are significant risks to achieving the current guaranteed substantial completion dates. WEC has also reported that it is continuing to develop detailed mitigation plans to address those risks. May 2016 Petition and September 2016 Settlement Agreement On May 26, 2016, SCE&G petitioned the SCPSC seeking approval to update the capital cost schedule and construction milestone schedule for the New Units consistent with the October 2015 Amendment. Within this petition, SCE&G also informed the SCPSC that it had notified WEC of its intent to elect the fixed price option, subject to concurrence by Santee Cooper and approval by the SCPSC. The petition reflected an increase in total project costs of approximately $852 million over the cost approved by the SCPSC in September 2015, of which approximately $505 million is directly attributable to the fixed price option. SCE&G's estimated gross construction cost for the project is now estimated to be approximately $7.7 billion, including owner’s costs, transmission, escalation and AFC. After receiving Santee Cooper's concurrence in June 2016, SCE&G executed the fixed price option on July 1, 2016, subject to SCPSC approval. On July 1, 2016, SCE&G amended the May 26, 2016 petition by withdrawing its request to adjust its transmission capital costs forecast in the amount of $4.3 million and revising its proposed capital cost schedule accordingly (along with the associated escalation and AFC). This revision was made while SCE&G evaluates alternatives to installing additional capacitors in Summer Station's existing Unit 1 switchyard. On September 1, 2016, SCE&G entered into a settlement agreement with ORS and certain other parties concerning SCE&G's May 26, 2016 petition. The settlement agreement supports approval of the fixed price option and the revised construction and capital cost schedules, including the guaranteed substantial completion dates of August 2019 and August 2020 for Units 2 and 3, respectively, and the inclusion of an additional $831 million in the capital cost schedule. The settling parties also agreed to revise the allowed return on equity for new nuclear construction from 10.5% to 10.25%. This revised return on equity would be applied prospectively for the purpose of calculating revised rates sought by SCE&G under the BLRA on and after January 1, 2017, until such time as the New Units are completed. In addition, SCE&G agreed that it will not file future requests to amend capital cost schedules prior to January 28, 2019. SCE&G also agreed that, in most circumstances, if the projected commercial operation date for Unit 2 is extended, the expiration of the January 28, 2019 moratorium will be extended by an equal amount of time. A public hearing on the petition, as amended, and the settlement agreement was held in October 2016, and the SCPSC is expected to issue its order in November 2016. Construction Milestone Payment Schedule and Related DRB Activity The October 2015 Amendment provided that the parties would agree upon a construction milestone payment schedule within five months of the effective date of the October 2015 Amendment or submit the issue to the DRB. The parties agreed to two one-month extensions for discussion of the schedule through July 2016. The parties were unable to reach an agreement on a schedule in that time period, and the owners referred the matter to the DRB on August 1, 2016. The dispute relates only to the timing of payments, with WEC asking for payments pursuant to a schedule which is more front loaded than the owners believe is appropriate. The total amount to be paid is not in dispute. A hearing was held by the DRB on August 30 and 31, 2016, prior to which the parties filed statements of position and information to substantiate their respective positions. In connection with the DRB proceeding, WEC expressed concerns with the adoption of owners' proposed construction milestone payment schedule and indicated that the cash flow provided by that payment schedule may adversely affect WEC's ability to complete the project successfully. On September 30, 2016, the parties received an order issued by the DRB instructing them to continue to work to develop a construction milestone payment schedule by November 3, 2016. The parties were unsuccessful in reaching an agreement by that date; therefore, the order provides that the DRB will conduct a further hearing on November 9, 2016, and will make a determination by November 30, 2016. During these efforts, payments will be made to WEC for October and November 2016 totaling $133 million (SCE&G's 55% portion being approximately $73.2 million) and $136.5 million (SCE&G's 55% portion being approximately $75.1 million), respectively. These payments are based on the DRB's findings concerning the approximate value of the work expected to be completed during these months and are in lieu of all other contractually-required payments related to (v) above during October and November 2016. Based upon the information that has been presented by WEC in connection with the hearing and with respect to the matters at issue generally, SCE&G cannot predict whether a decision by the DRB which is more favorable to the owners will adversely affect WEC’s ability to complete the project or the construction schedule and costs. As of September 30, 2016, payments related to (i) above had been made totaling $187.5 million (SCE&G's 55% portion being approximately $103.1 million ). Also as of September 30, 2016, payments related to (v) above had been made totaling $930 million (SCE&G's 55% portion being $511.5 million ), which included payments made during the initial five-month period described above, as required under the contract and payments agreed upon by the parties during the extensions described above and during the period the DRB was reviewing the matter. Payment and Performance Obligations Payment and performance obligations under the EPC Contract are joint and several obligations of WEC and Stone & Webster, and in connection with the October 2015 Amendment, Toshiba Corporation, WEC’s parent company, reaffirmed its guaranty of WEC’s payment obligations. Additionally, the EPC Contract provides the owners the right, exercisable upon certain conditions, to obtain payment and performance bonds from WEC equal to 15% of the highest three months billings during the applicable year, and their aggregate nominal coverage will not excee d $100 million (or $55 million for SCE&G's 55% share). SCE&G and Santee Cooper are responsible for the cost of the bonds. In late 2015, Toshiba's credit ratings declined to below investment grade following disclosures regarding its operating and financial performance and near-term liquidity. As a result, pursuant to the above-described terms of the EPC Contract, SCE&G has obtained standby letters of credit in lieu of payment and performance bonds from WEC totalin g $45 million (or approximatel y $25 million for SCE&G's 55% share). These standby letters of credit expire annually and automatically renew for successive one-year periods until their final expiration date of August 31, 2020, unless the issuer provides a minimum 60-day notice that it will not renew. In the event that WEC would be unable to meet its payment and performance obligations under the EPC Contract, it is anticipated this funding would provide a source of liquidity to assist in an orderly transition and in enabling construction activities to continue. In addition, the EPC Contract provides that upon the request of SCE&G, the Consortium must escrow certain intellectual property and software for SCE&G's benefit to enable completion of the New Units. An escrow arrangement and a schedule for deposit of intellectual property and software are being developed. Additional claims by the Consortium or SCE&G involving the project schedule and budget may arise as the project continues. The parties to the EPC Contract have established both informal and formal dispute resolution procedures in order to resolve such issues. SCE&G expects to resolve all disputes through both the informal and formal procedures and currently anticipates that any project costs that arise through such dispute resolution processes (including those reflected in the October 2015 Amendment described above), as well as other project costs identified from time to time, will be recoverable through rates. Santee Cooper Matters As noted above, SCE&G has agreed to acquire an additional 5% ownership in the New Units from Santee Cooper. Under the terms of this agreement, SCE&G will acquire a 1% ownership interest in the New Units at the commercial operation date of Unit 2, an additional 2% ownership interest no later than the first anniversary of such commercial operation date, and the final 2% no later than the second anniversary of such commercial operation date. SCE&G has agreed to pay an amount equal to Santee Cooper's actual cost, including its cost of financing, of the percentage conveyed as of the date of each conveyance. In addition, the agreement provides that Santee Cooper will not transfer any of its remaining interest in the New Units to third parties until the New Units are complete. This transaction is subject to customary closing conditions, including receipt of necessary regulatory approvals. This transaction will not affect the payment obligations between the parties during construction for the New Units, nor is it anticipated that the payments for the additional ownership interest would be reflected in a revised rates filing under the BLRA. Based on the October 2015 Amendment, SCE&G’s projected cost would be approximately $850 million for the additional 5% interest being acquired from Santee Cooper if the fixed price option is approved by the SCPSC. Nuclear Production Tax Credits The IRS has notified SCE&G that, subject to a national megawatt capacity limitation, the electricity to be produced by each of the New Units (advanced nuclear units, as defined) would qualify for nuclear production tax credits under Section 45J of the IRC to the extent that such New Unit is operational before January 1, 2021 and other eligibility requirements are met. These nuclear production tax credits (related to SCE&G's 55% share of both New Units) could total as much as approximately $1.4 billion . Such credits would be earned over the first eight years of each New Unit's operations and would be realized by SCE&G over those years or during allowable carry-forward periods. Based on the guaranteed substantial completion dates provided above, both New Units are expected to be operational and to qualify for the nuclear production tax credits; however, further delays in the schedule or changes in tax law could impact such conclusions. When and to the extent that production tax credits are realized, their benefits are expected to be provided directly to SCE&G's electric customers. Other Project Matters When the NRC issued the COLs for the New Units, two of the conditions that it imposed were requiring inspection and testing of certain components of the New Units' passive cooling system, and requiring the development of strategies to respond to extreme natural events resulting in the loss of power at the New Units. In addition, the NRC directed the Office of New Reactors to issue to SCE&G an order requiring enhanced, reliable spent fuel pool instrumentation. SCE&G prepared and submitted an overall integration plan for the New Units to the NRC in August 2013. That plan remains under review by the NRC and SCE&G does not anticipate any additional regulatory actions as a result of that review, but it cannot predict future regulatory activities or how such initiatives would impact construction or operation of the New Units. Environmental On August 3, 2015, the EPA issued its final rule on emission guidelines for states to follow in developing plans to address GHG emissions from existing units. The rule includes state-specific goals for reducing national carbon dioxide emissions by 32% from 2005 levels by 2030. The rule also provides for nuclear reactors under construction, such as the New Units, to count towards compliance and establishes a phased-in compliance approach beginning in 2022. The rule gives each state from one to three years to issue SIPs, which will ultimately define the specific compliance methodology that will be applied to existing units in that state. On February 9, 2016, the Supreme Court stayed the rule pending disposition of a petition of review of the rule in the Court of Appeals. The order of the Supreme Court has no immediate impact on SCE&G and GENCO or their generation operations. The Company and Consolidated SCE&G are currently evaluating the rule and expect any costs incurred to comply with such rule to be recoverable through rates. In July 2011, the EPA issued the CSAPR to reduce emissions of sulfur dioxide and nitrogen oxide from power plants in the eastern half of the United States. A series of court actions stayed this rule until October 23, 2014, when the Court of Appeals granted a motion to lift the stay. On December 3, 2014, the EPA published an interim final rule that aligns the dates in the CSAPR text with the revised court-ordered schedule, which delayed the implementation dates to 2015 for Phase 1 and to 2017 for Phase 2. The CSAPR replaces the CAIR and requires a total of 28 states to reduce annual sulfur dioxide emissions and annual and ozone season nitrogen oxide emissions to assist in attaining the ozone and fine particle NAAQS. The rule establishes an emissions cap for sulfur dioxide and nitrogen oxide and limits the trading for emission allowances by separating affected states into two groups with no trading between the groups. On July 28, 2015, the Court of Appeals held that Phase 2 emissions budgets for certain states, including South Carolina, required reductions in emissions beyond the point necessary to achieve downwind attainment and were, therefore, invalid. The Court of Appeals remanded CSAPR, without vacating the rule, to the EPA for further consideration. The opinion of the Court of Appeals has no immediate impact on SCE&G and GENCO or their generation operations. The State of South Carolina has chosen to remain in the CSAPR program, even though recent court rulings exempted the state. This allows the state to remain compliant with regional haze standards. Air quality control installations that SCE&G and GENCO have already completed have positioned them to comply with the existing allowances set by the CSAPR. Any costs incurred to comply with CSAPR are expected to be recoverable through rates. In April 2012, the EPA's MATS rule containing new standards for mercury and other specified air pollutants became effective. On November 19, 2014, the EPA finalized its reconsideration of certain provisions applicable during startup and shutdown of generating facilities under the MATS rule. SCE&G and GENCO were granted a one year extension (through April 2016) to comply with MATS at Cope, McMeekin, Wateree and Williams Stations. These extensions allowed time to convert McMeekin Station to burn natural gas and to install additional pollution control devices at the other plants to enhance the control of certain MATS-regulated pollutants. In addition, SCE&G retired certain other coal-fired units during this time frame. The MATS rule has been the subject of ongoing litigation even while it remains in effect. Rulings on this litigation are not expected to have an impact on SCE&G or GENCO due to these retirements, conversions, and enhancements. SCE&G and GENCO currently are in compliance with the MATS rule and expect to remain in compliance. The CWA provides for the imposition of effluent limitations that require treatment for wastewater discharges. Under the CWA, compliance with applicable limitations is achieved under state-issued NPDES permits. As a facility’s NPDES permit is renewed (every five years), any new effluent limitations would be incorporated. The ELG Rule became effective on January 4, 2016. After this date, state regulators will modify facility NPDES permits to match more restrictive standards, thus requiring facilities to retrofit with new wastewater treatment technologies. Compliance dates will vary by type of wastewater, and some will be based on a facility's five year permit cycle and thus may range from 2018 to 2023. The Company and Consolidated SCE&G expect that wastewater treatment technology retrofits will be required at Williams and Wateree Stations. Any costs incurred to comply with the ELG Rule are expected to be recoverable through rates. The CWA Section 316(b) Existing Facilities Rule became effective in October 2014. This rule establishes national requirements for the location, design, construction and capacity of cooling water intake structures at existing facilities that reflect the best technology available for minimizing the adverse environmental impacts of impingement and entrainment. SCE&G and GENCO are conducting studies and implementing plans as required by the rule to determine appropriate intake structure modifications to ensure compliance with this rule. Any costs incurred to comply with this rule are expected to be recoverable through rates. The EPA's final rule for CCR became effective in the fourth quarter of 2015. This rule regulates CCR as a non-hazardous waste under Subtitle D of the Resource Conservation and Recovery Act and imposes certain requirements on ash storage ponds and other CCR management facilities at SCE&G's and GENCO's coal-fired generating facilities. SCE&G and GENCO have already closed or have begun the process of closure of all of their ash storage ponds and have previously recognized AROs for such ash storage ponds under existing requirements. The Company and Consolidated SCE&G do not expect the incremental compliance costs associated with this rule to be significant and expect to recover such costs in future rates. The Nuclear Waste Act required that the United States government accept and permanently dispose of high-level radioactive waste and spent nuclear fuel by January 31, 1998, and it imposed on utilities the primary responsibility for storage of |

Commitments and Contingencies Disclosure [Text Block] | COMMITMENTS AND CONTINGENCIES Nuclear Insurance Under Price-Anderson, SCE&G (for itself and on behalf of Santee Cooper, a one-third owner of Summer Station Unit 1) maintains agreements of indemnity with the NRC that, together with private insurance, cover third-party liability arising from any nuclear incident occurring at SCE&G's nuclear power plant. Price-Anderson provides funds up to $13.4 billion for public liability claims that could arise from a single nuclear incident. Each nuclear plant is insured against this liability to a maximum of $375 million by ANI with the remaining coverage provided by a mandatory program of deferred premiums that could be assessed, after a nuclear incident, against all owners of commercial nuclear reactors. Each reactor licensee is currently liable for up to $127.3 million per reactor owned for each nuclear incident occurring at any reactor in the United States, provided that not more than $18.9 million of the liability per reactor would be assessed per year. SCE&G’s maximum assessment, based on its two-thirds ownership of Summer Station Unit 1, would be $84.8 million per incident, but not more than $12.6 million per year. Both the maximum assessment per reactor and the maximum yearly assessment are adjusted for inflation at least every five years. SCE&G currently maintains insurance policies (for itself and on behalf of Santee Cooper) with NEIL. The policies provide coverage to Summer Station Unit 1 for property damage and outage costs up to $2.75 billion resulting from an event of nuclear origin and up to $2.33 billion resulting from an event of a non-nuclear origin. In addition, a builder's risk insurance policy has been purchased from NEIL for the construction of the New Units. This policy provides the owners of the New Units up to $500 million of total coverage for accidental property damage occurring during construction. The NEIL policies, in the aggregate, are subject to a maximum loss of $2.75 billion for any single loss occurrence. All of the NEIL policies permit retrospective assessments under certain conditions to cover insurer’s losses. Based on the current annual premium, SCE&G’s portion of the retrospective premium assessment would not exceed $45.8 million . SCE&G currently maintains an excess property insurance policy (for itself and on behalf of Santee Cooper) with EMANI. The policy provides coverage to Summer Station Unit 1 for property damage and outage costs up to $415 million resulting from an event of a non-nuclear origin. The EMANI policy permits retrospective assessments under certain conditions to cover insurer's losses. Based on the current annual premium, SCE&G's portion of the retrospective premium assessment would not exceed $1.8 million . To the extent that insurable claims for property damage, decontamination, repair and replacement and other costs and expenses arising from an incident at Summer Station Unit 1 exceed the policy limits of insurance, or to the extent such insurance becomes unavailable in the future, and to the extent that SCE&G's rates would not recover the cost of any purchased replacement power, SCE&G will retain the risk of loss as a self-insurer. SCE&G has no reason to anticipate a serious nuclear or other incident. However, if such an incident were to occur, it likely would have a material impact on the Company’s and Consolidated SCE&G's results of operations, cash flows and financial position. New Nuclear Construction In 2008, SCE&G, on behalf of itself and as agent for Santee Cooper, contracted with the Consortium for the design and construction of the New Units at the site of Summer Station. SCE&G's current ownership share in the New Units is 55% . As discussed below, SCE&G has agreed to acquire an additional 5% ownership in the New Units from Santee Cooper. EPC Contract and BLRA Matters The construction of the New Units and SCE&G’s related recovery of financing costs through rates is subject to review and approval by the SCPSC as provided for in the BLRA. Under the BLRA, the SCPSC has approved, among other things, a milestone schedule and a capital costs estimates schedule for the New Units. This approval constitutes a final and binding determination that the New Units are used and useful for utility purposes, and that the capital costs associated with the New Units are prudent utility costs and expenses and are properly included in rates, so long as the New Units are constructed or are being constructed within the parameters of the approved milestone schedule, including specified contingencies, and the approved capital costs estimates schedule. Subject to the same conditions, the BLRA provides that SCE&G may apply to the SCPSC annually for an order to recover through revised rates SCE&G’s weighted average cost of capital applied to all or part of the outstanding balance of construction work in progress concerning the New Units. As of September 30, 2016, SCE&G’s investment in the New Units, including related transmission, totaled $4.2 billion , for which the financing costs on $3.2 billion have been reflected in rates under the BLRA. The SCPSC granted initial approval of the construction schedule and related forecasted capital costs in 2009. The NRC issued COLs in March 2012. In November 2012, the SCPSC approved an updated milestone schedule and additional updated capital costs for the New Units. In addition, the SCPSC approved revised substantial completion dates for the New Units based on that March 2012 issuance of the COL and the amounts agreed upon by SCE&G and the Consortium in July 2012 to resolve known claims by the Consortium for costs related to COL delays, design modifications of the shield building and certain prefabricated structural modules for the New Units and unanticipated rock conditions at the site. In October 2014, the South Carolina Supreme Court affirmed the SCPSC's order on appeal. Since the settlement of delay-related claims in 2012, the Consortium has continued to experience delays in the schedule. Shield building construction remains a principal focus area for SCE&G’s oversight of the project. The primary critical path for Unit 2 and Unit 3 runs through the reinforced concrete activities necessary to support placement of shield building panels and the completion of shield building construction. WEC has reached agreement on a mitigation plan to accelerate shield building panel fabrication with one of its subcontractors. Additional mitigation will be required in the critical path to support the updated substantial completion dates described below. During the fourth quarter of 2013, the Consortium began a full re-baselining of the Unit 2 and Unit 3 construction schedules to incorporate a more detailed evaluation of the engineering and procurement activities necessary to accomplish the schedules and to provide a detailed reassessment of the impact of the revised Unit 2 and Unit 3 schedules on engineering and design resource allocations, procurement, construction work crew efficiencies and other items. The result was a revised fully integrated project schedule with timing of specific construction activities (Revised, Fully-Integrated Construction Schedule) along with related cost information. The Revised, Fully-Integrated Construction Schedule initially indicated that the substantial completion of Unit 2 was expected to occur in June 2019 and that the substantial completion of Unit 3 was expected to be approximately 12 months later. However, the Consortium continued to refine and update the Revised, Fully-Integrated Construction Schedule as certain designs were finalized, as construction progressed, and as additional information was received. See discussion of October 2015 Amendment below. In September 2015, the SCPSC approved an updated BLRA milestone schedule based on revised substantial completion dates for Units 2 and 3 of June 2019 and June 2020, respectively, each subject to an 18-month contingency period. In addition, the SCPSC approved certain updated owner's costs ( $245 million ) and other capital costs ( $453 million ), of which $539 million were associated with the schedule delays and other contested costs. In this proceeding, SCE&G's total projected capital costs (in 2007 dollars) and estimated gross construction cost (including escalation and AFC) were estimated to be $5.2 billion and $6.8 billion , respectively. These projections included amounts related to the Revised, Fully-Integrated Construction Schedule for which SCE&G had not accepted responsibility and which were the subject of dispute. As such, the updated milestone schedule and projections did not reflect the resolution of negotiations. In addition, the SCPSC approved a revision to the allowed return on equity for new nuclear construction from 11.0% to 10.5% . This revised return on equity was to be applied prospectively for the purpose of calculating revised rates sought by SCE&G under the BLRA on and after January 1, 2016, until such time as the New Units are completed. However, see discussion of May 2016 Petition and September 2016 Settlement Agreement below. October 2015 Amendment On October 27, 2015, SCE&G, Santee Cooper and the Consortium reached a settlement regarding the above mentioned disputes, and the EPC Contract was amended. The October 2015 Amendment became effective in December 2015, upon the consummation of the acquisition by WEC of the stock of Stone & Webster from CB&I. Following that acquisition, Stone & Webster continues to be a member of the Consortium as a subsidiary of WEC rather than CB&I, and WEC has engaged Fluor as a subcontracted construction manager. Among other things, the October 2015 Amendment: (i) resolved by settlement and release most outstanding disputes between SCE&G and the Consortium, in exchange for (a) an additional cost to be paid by SCE&G and Santee Cooper of $300 million (SCE&G’s 55% portion being $165 million ) and an increase in the fixed component of the contract price by that amount, and (b) a credit to SCE&G and Santee Cooper of $50 million (SCE&G’s 55% portion being approximately $27 million ) to be applied to the target component of the contract price, (ii) revised the guaranteed substantial completion dates of Units 2 and 3 to August 31, 2019 and 2020, respectively, (iii) revised the delay-related liquidated damages computation requirements, including those related to the eligibility of the New Units to earn Internal Revenue Code Section 45J production tax credits (see also below), and capped those aggregate liquidated damages at $463 million per New Unit (SCE&G’s 55% portion being approximately $255 million per New Unit), (iv) provided for payment to the Consortium of a completion bonus of $275 million per New Unit (SCE&G’s 55% portion being approximately $151 million per New Unit) for each New Unit placed in service by the deadline to qualify for production tax credits, (v) provided for development of a revised construction milestone payment schedule, with SCE&G and Santee Cooper making monthly payments of $100 million (SCE&G’s 55% portion being $55 million ) for each of the first five months following effectiveness, followed by payments made based on milestones achieved, (vi) provided that SCE&G and Santee Cooper waive and cancel the CB&I parent company guaranty with respect to the project, (vii) provided for an explicit definition of Change in Law designed to reduce the likelihood of certain future commercial disputes, with the Consortium also acknowledging and agreeing that the project scope includes providing New Units that meet the standards of the NRC approved Design Control Document Revision 19, (viii) established a DRB process for certain commercial claims and disputes, and (ix) eliminated the requirement or ability of any party to bring suit regarding disputes before substantial completion of the project. The DRB is comprised of three members chosen by the parties to resolve construction-related claims. Amounts in dispute of less than $5 million will be resolved by the DRB without recourse, and amounts in dispute greater than $5 million will be resolved by the DRB for the remainder of the construction of the New Units, with a reserved right to further arbitrate or to litigate such issues at the conclusion of construction. Under the October 2015 Amendment, SCE&G’s total estimated project costs increased over the $6.8 billion approved by the SCPSC in September 2015. In addition, SCE&G has updated project costs for estimated change orders related to certain outstanding disputes not resolved by the October 2015 Amendment. As a result, SCE&G's estimated gross construction cost for the project (including the effects of these change orders, escalation and AFC but excluding the fixed price option described below) totaled approximately $7.2 billion . The October 2015 Amendment also provided SCE&G and Santee Cooper an irrevocable option, until November 1, 2016 and subject to regulatory approvals, to further amend the EPC Contract to fix the total amount to be paid to the Consortium for its entire scope of work on the project (excluding a limited amount of work within the time and materials component of the contract price) after June 30, 2015 at $6.082 billion (SCE&G’s 55% portion being approximately $3.345 billion ). This total amount to be paid would be reduced by amounts paid since June 30, 2015. Under the fixed price option, the aggregate delay-related liquidated damages referred to in (iii) above would be capped at $338 million per New Unit (SCE&G’s 55% portion being approximately $186 million per New Unit), and the completion bonus referred to in (iv) above would be $150 million per New Unit (SCE&G’s 55% portion being approximately $83 million per New Unit). See information below regarding the execution of this fixed price option, subject to SCPSC approval. WEC has engaged Fluor to review and confirm the project schedule. The owners understand that this process has not been completed. The analysis by Fluor, to the extent that it is shared with the owners, could affect the owners’ expectations regarding the project schedule. In a discussion of the project status on September 26, 2016, and in response to SCE&G’s specific questioning regarding work crew efficiency and productivity and schedule mitigation efforts, WEC executive management stated that it had no reason to believe that the August 2019 and 2020 guaranteed completion dates would not be met. WEC submits monthly schedule updates, however, and it has reported that there are significant risks to achieving the current guaranteed substantial completion dates. WEC has also reported that it is continuing to develop detailed mitigation plans to address those risks. May 2016 Petition and September 2016 Settlement Agreement On May 26, 2016, SCE&G petitioned the SCPSC seeking approval to update the capital cost schedule and construction milestone schedule for the New Units consistent with the October 2015 Amendment. Within this petition, SCE&G also informed the SCPSC that it had notified WEC of its intent to elect the fixed price option, subject to concurrence by Santee Cooper and approval by the SCPSC. The petition reflected an increase in total project costs of approximately $852 million over the cost approved by the SCPSC in September 2015, of which approximately $505 million is directly attributable to the fixed price option. SCE&G's estimated gross construction cost for the project is now estimated to be approximately $7.7 billion, including owner’s costs, transmission, escalation and AFC. After receiving Santee Cooper's concurrence in June 2016, SCE&G executed the fixed price option on July 1, 2016, subject to SCPSC approval. On July 1, 2016, SCE&G amended the May 26, 2016 petition by withdrawing its request to adjust its transmission capital costs forecast in the amount of $4.3 million and revising its proposed capital cost schedule accordingly (along with the associated escalation and AFC). This revision was made while SCE&G evaluates alternatives to installing additional capacitors in Summer Station's existing Unit 1 switchyard. On September 1, 2016, SCE&G entered into a settlement agreement with ORS and certain other parties concerning SCE&G's May 26, 2016 petition. The settlement agreement supports approval of the fixed price option and the revised construction and capital cost schedules, including the guaranteed substantial completion dates of August 2019 and August 2020 for Units 2 and 3, respectively, and the inclusion of an additional $831 million in the capital cost schedule. The settling parties also agreed to revise the allowed return on equity for new nuclear construction from 10.5% to 10.25%. This revised return on equity would be applied prospectively for the purpose of calculating revised rates sought by SCE&G under the BLRA on and after January 1, 2017, until such time as the New Units are completed. In addition, SCE&G agreed that it will not file future requests to amend capital cost schedules prior to January 28, 2019. SCE&G also agreed that, in most circumstances, if the projected commercial operation date for Unit 2 is extended, the expiration of the January 28, 2019 moratorium will be extended by an equal amount of time. A public hearing on the petition, as amended, and the settlement agreement was held in October 2016, and the SCPSC is expected to issue its order in November 2016. Construction Milestone Payment Schedule and Related DRB Activity The October 2015 Amendment provided that the parties would agree upon a construction milestone payment schedule within five months of the effective date of the October 2015 Amendment or submit the issue to the DRB. The parties agreed to two one-month extensions for discussion of the schedule through July 2016. The parties were unable to reach an agreement on a schedule in that time period, and the owners referred the matter to the DRB on August 1, 2016. The dispute relates only to the timing of payments, with WEC asking for payments pursuant to a schedule which is more front loaded than the owners believe is appropriate. The total amount to be paid is not in dispute. A hearing was held by the DRB on August 30 and 31, 2016, prior to which the parties filed statements of position and information to substantiate their respective positions. In connection with the DRB proceeding, WEC expressed concerns with the adoption of owners' proposed construction milestone payment schedule and indicated that the cash flow provided by that payment schedule may adversely affect WEC's ability to complete the project successfully. On September 30, 2016, the parties received an order issued by the DRB instructing them to continue to work to develop a construction milestone payment schedule by November 3, 2016. The parties were unsuccessful in reaching an agreement by that date; therefore, the order provides that the DRB will conduct a further hearing on November 9, 2016, and will make a determination by November 30, 2016. During these efforts, payments will be made to WEC for October and November 2016 totaling $133 million (SCE&G's 55% portion being approximately $73.2 million) and $136.5 million (SCE&G's 55% portion being approximately $75.1 million), respectively. These payments are based on the DRB's findings concerning the approximate value of the work expected to be completed during these months and are in lieu of all other contractually-required payments related to (v) above during October and November 2016. Based upon the information that has been presented by WEC in connection with the hearing and with respect to the matters at issue generally, SCE&G cannot predict whether a decision by the DRB which is more favorable to the owners will adversely affect WEC’s ability to complete the project or the construction schedule and costs. As of September 30, 2016, payments related to (i) above had been made totaling $187.5 million (SCE&G's 55% portion being approximately $103.1 million ). Also as of September 30, 2016, payments related to (v) above had been made totaling $930 million (SCE&G's 55% portion being $511.5 million ), which included payments made during the initial five-month period described above, as required under the contract and payments agreed upon by the parties during the extensions described above and during the period the DRB was reviewing the matter. Payment and Performance Obligations Payment and performance obligations under the EPC Contract are joint and several obligations of WEC and Stone & Webster, and in connection with the October 2015 Amendment, Toshiba Corporation, WEC’s parent company, reaffirmed its guaranty of WEC’s payment obligations. Additionally, the EPC Contract provides the owners the right, exercisable upon certain conditions, to obtain payment and performance bonds from WEC equal to 15% of the highest three months billings during the applicable year, and their aggregate nominal coverage will not excee d $100 million (or $55 million for SCE&G's 55% share). SCE&G and Santee Cooper are responsible for the cost of the bonds. In late 2015, Toshiba's credit ratings declined to below investment grade following disclosures regarding its operating and financial performance and near-term liquidity. As a result, pursuant to the above-described terms of the EPC Contract, SCE&G has obtained standby letters of credit in lieu of payment and performance bonds from WEC totalin g $45 million (or approximatel y $25 million for SCE&G's 55% share). These standby letters of credit expire annually and automatically renew for successive one-year periods until their final expiration date of August 31, 2020, unless the issuer provides a minimum 60-day notice that it will not renew. In the event that WEC would be unable to meet its payment and performance obligations under the EPC Contract, it is anticipated this funding would provide a source of liquidity to assist in an orderly transition and in enabling construction activities to continue. In addition, the EPC Contract provides that upon the request of SCE&G, the Consortium must escrow certain intellectual property and software for SCE&G's benefit to enable completion of the New Units. An escrow arrangement and a schedule for deposit of intellectual property and software are being developed. Additional claims by the Consortium or SCE&G involving the project schedule and budget may arise as the project continues. The parties to the EPC Contract have established both informal and formal dispute resolution procedures in order to resolve such issues. SCE&G expects to resolve all disputes through both the informal and formal procedures and currently anticipates that any project costs that arise through such dispute resolution processes (including those reflected in the October 2015 Amendment described above), as well as other project costs identified from time to time, will be recoverable through rates. Santee Cooper Matters As noted above, SCE&G has agreed to acquire an additional 5% ownership in the New Units from Santee Cooper. Under the terms of this agreement, SCE&G will acquire a 1% ownership interest in the New Units at the commercial operation date of Unit 2, an additional 2% ownership interest no later than the first anniversary of such commercial operation date, and the final 2% no later than the second anniversary of such commercial operation date. SCE&G has agreed to pay an amount equal to Santee Cooper's actual cost, including its cost of financing, of the percentage conveyed as of the date of each conveyance. In addition, the agreement provides that Santee Cooper will not transfer any of its remaining interest in the New Units to third parties until the New Units are complete. This transaction is subject to customary closing conditions, including receipt of necessary regulatory approvals. This transaction will not affect the payment obligations between the parties during construction for the New Units, nor is it anticipated that the payments for the additional ownership interest would be reflected in a revised rates filing under the BLRA. Based on the October 2015 Amendment, SCE&G’s projected cost would be approximately $850 million for the additional 5% interest being acquired from Santee Cooper if the fixed price option is approved by the SCPSC. Nuclear Production Tax Credits The IRS has notified SCE&G that, subject to a national megawatt capacity limitation, the electricity to be produced by each of the New Units (advanced nuclear units, as defined) would qualify for nuclear production tax credits under Section 45J of the IRC to the extent that such New Unit is operational before January 1, 2021 and other eligibility requirements are met. These nuclear production tax credits (related to SCE&G's 55% share of both New Units) could total as much as approximately $1.4 billion . Such credits would be earned over the first eight years of each New Unit's operations and would be realized by SCE&G over those years or during allowable carry-forward periods. Based on the guaranteed substantial completion dates provided above, both New Units are expected to be operational and to qualify for the nuclear production tax credits; however, further delays in the schedule or changes in tax law could impact such conclusions. When and to the extent that production tax credits are realized, their benefits are expected to be provided directly to SCE&G's electric customers. Other Project Matters When the NRC issued the COLs for the New Units, two of the conditions that it imposed were requiring inspection and testing of certain components of the New Units' passive cooling system, and requiring the development of strategies to respond to extreme natural events resulting in the loss of power at the New Units. In addition, the NRC directed the Office of New Reactors to issue to SCE&G an order requiring enhanced, reliable spent fuel pool instrumentation. SCE&G prepared and submitted an overall integration plan for the New Units to the NRC in August 2013. That plan remains under review by the NRC and SCE&G does not anticipate any additional regulatory actions as a result of that review, but it cannot predict future regulatory activities or how such initiatives would impact construction or operation of the New Units. Environmental On August 3, 2015, the EPA issued its final rule on emission guidelines for states to follow in developing plans to address GHG emissions from existing units. The rule includes state-specific goals for reducing national carbon dioxide emissions by 32% from 2005 levels by 2030. The rule also provides for nuclear reactors under construction, such as the New Units, to count towards compliance and establishes a phased-in compliance approach beginning in 2022. The rule gives each state from one to three years to issue SIPs, which will ultimately define the specific compliance methodology that will be applied to existing units in that state. On February 9, 2016, the Supreme Court stayed the rule pending disposition of a petition of review of the rule in the Court of Appeals. The order of the Supreme Court has no immediate impact on SCE&G and GENCO or their generation operations. The Company and Consolidated SCE&G are currently evaluating the rule and expect any costs incurred to comply with such rule to be recoverable through rates. In July 2011, the EPA issued the CSAPR to reduce emissions of sulfur dioxide and nitrogen oxide from power plants in the eastern half of the United States. A series of court actions stayed this rule until October 23, 2014, when the Court of Appeals granted a motion to lift the stay. On December 3, 2014, the EPA published an interim final rule that aligns the dates in the CSAPR text with the revised court-ordered schedule, which delayed the implementation dates to 2015 for Phase 1 and to 2017 for Phase 2. The CSAPR replaces the CAIR and requires a total of 28 states to reduce annual sulfur dioxide emissions and annual and ozone season nitrogen oxide emissions to assist in attaining the ozone and fine particle NAAQS. The rule establishes an emissions cap for sulfur dioxide and nitrogen oxide and limits the trading for emission allowances by separating affected states into two groups with no trading between the groups. On July 28, 2015, the Court of Appeals held that Phase 2 emissions budgets for certain states, including South Carolina, required reductions in emissions beyond the point necessary to achieve downwind attainment and were, therefore, invalid. The Court of Appeals remanded CSAPR, without vacating the rule, to the EPA for further consideration. The opinion of the Court of Appeals has no immediate impact on SCE&G and GENCO or their generation operations. The State of South Carolina has chosen to remain in the CSAPR program, even though recent court rulings exempted the state. This allows the state to remain compliant with regional haze standards. Air quality control installations that SCE&G and GENCO have already completed have positioned them to comply with the existing allowances set by the CSAPR. Any costs incurred to comply with CSAPR are expected to be recoverable through rates. In April 2012, the EPA's MATS rule containing new standards for mercury and other specified air pollutants became effective. On November 19, 2014, the EPA finalized its reconsideration of certain provisions applicable during startup and shutdown of generating facilities under the MATS rule. SCE&G and GENCO were granted a one year extension (through April 2016) to comply with MATS at Cope, McMeekin, Wateree and Williams Stations. These extensions allowed time to convert McMeekin Station to burn natural gas and to install additional pollution control devices at the other plants to enhance the control of certain MATS-regulated pollutants. In addition, SCE&G retired certain other coal-fired units during this time frame. The MATS rule has been the subject of ongoing litigation even while it remains in effect. Rulings on this litigation are not expected to have an impact on SCE&G or GENCO due to these retirements, conversions, and enhancements. SCE&G and GENCO currently are in compliance with the MATS rule and expect to remain in compliance. The CWA provides for the imposition of effluent limitations that require treatment for wastewater discharges. Under the CWA, compliance with applicable limitations is achieved under state-issued NPDES permits. As a facility’s NPDES permit is renewed (every five years), any new effluent limitations would be incorporated. The ELG Rule became effective on January 4, 2016. After this date, state regulators will modify facility NPDES permits to match more restrictive standards, thus requiring facilities to retrofit with new wastewater treatment technologies. Compliance dates will vary by type of wastewater, and some will be based on a facility's five year permit cycle and thus may range from 2018 to 2023. The Company and Consolidated SCE&G expect that wastewater treatment technology retrofits will be required at Williams and Wateree Stations. Any costs incurred to comply with the ELG Rule are expected to be recoverable through rates. The CWA Section 316(b) Existing Facilities Rule became effective in October 2014. This rule establishes national requirements for the location, design, construction and capacity of cooling water intake structures at existing facilities that reflect the best technology available for minimizing the adverse environmental impacts of impingement and entrainment. SCE&G and GENCO are conducting studies and implementing plans as required by the rule to determine appropriate intake structure modifications to ensure compliance with this rule. Any costs incurred to comply with this rule are expected to be recoverable through rates. The EPA's final rule for CCR became effective in the fourth quarter of 2015. This rule regulates CCR as a non-hazardous waste under Subtitle D of the Resource Conservation and Recovery Act and imposes certain requirements on ash storage ponds and other CCR management facilities at SCE&G's and GENCO's coal-fired generating facilities. SCE&G and GENCO have already closed or have begun the process of closure of all of their ash storage ponds and have previously recognized AROs for such ash storage ponds under existing requirements. The Company and Consolidated SCE&G do not expect the incremental compliance costs associated with this rule to be significant and expect to recover such costs in future rates. The Nuclear Waste Act required that the United States government accept and permanently dispose of high-level radioactive waste and spent nuclear fuel by January 31, 1998, and it imposed on utilities the primary responsibility for storage of |

SUMMARY OF SIGNIFICANT ACCOUN22
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 9 Months Ended |
Sep. 30, 2016 | |
Significant Accounting Policies | |
Basis Of Consolidation And Variable Interest Entities [Policy Text Block] | Basis of Consolidation and Variable Interest Entities The condensed consolidated financial statements of the Company include, after eliminating intercompany balances and transactions, the accounts of the parent holding company and each of its subsidiaries, including Consolidated SCE&G. Accordingly, discussions regarding the Company's financial results necessarily include the results of Consolidated SCE&G. SCE&G has determined that it has a controlling financial interest in GENCO and Fuel Company (which are considered to be VIEs) and, accordingly, Consolidated SCE&G's condensed consolidated financial statements include the accounts of SCE&G, GENCO and Fuel Company. The equity interests in GENCO and Fuel Company are held solely by SCANA, SCE&G’s parent. As a result, GENCO’s and Fuel Company’s equity and results of operations are reflected as noncontrolling interest in Consolidated SCE&G’s condensed consolidated financial statements. GENCO owns a coal-fired electric generating station with a 605 MW net generating capacity (summer rating). GENCO’s electricity is sold, pursuant to a FERC-approved tariff, solely to SCE&G under the terms of a power purchase agreement and related operating agreement. The effects of these transactions are eliminated in consolidation. Substantially all of GENCO’s property (carrying value of approximately $483 million ) serves as collateral for its long-term borrowings. Fuel Company acquires, owns and provides financing for SCE&G’s nuclear fuel, certain fossil fuels and emission and other environmental allowances. See also Note 4. |
Income Statement policy [Policy Text Block] | Income Statement Presentation Revenues and expenses arising from regulated businesses and, in the case of the Company, retail natural gas marketing businesses (including those activities of segments described in Note 10) are presented within Operating Income, and all other activities are presented within Other Income (Expense). Consistent with this presentation, the Company presents the 2015 gain on the sale of CGT within Operating Income and the 2015 gain on the sale of SCI within Other Income (Expense). |
Asset Management and Supply Service Agreements | Asset Management and Supply Service Agreement PSNC Energy, a subsidiary of SCANA, utilizes an asset management and supply service agreement with a counterparty for certain natural gas storage facilities. Such counterparty held, through an agency relationship, 41% and 46% of PSNC Energy’s natural gas inventory at September 30, 2016 and December 31, 2015, respectively, with a carrying value of $13.1 million and $17.7 million , respectively. Under the terms of the asset management agreement, PSNC Energy receives storage asset management fees of which 75% are credited to rate payers. No fees are received under the supply service agreement. This agreement expires on March 31, 2017. |
Earnings Per Share [Text Block] | Earnings Per Share The Company computes basic earnings per share by dividing net income by the weighted average number of common shares outstanding for the period. When applicable, the Company computes diluted earnings per share using this same formula, after giving effect to securities considered to be dilutive potential common stock utilizing the treasury stock method. |
Dispositions [Policy Text Block] | Dispositions In the first quarter of 2015, SCANA sold CGT and SCI. CGT was an interstate natural gas pipeline regulated by FERC that transported natural gas in South Carolina and southeastern Georgia, and it was sold to Dominion Resources, Inc. SCI provided fiber optic communications and other services and built, managed and leased communications towers in several southeastern states, and it was sold to a subsidiary of Spirit Communications. These sales resulted in recognition of pre-tax gains totaling approximately $342 million . As previously noted, the pre-tax gain from the sale of CGT is included within Operating Income and the pre-tax gain from the sale of SCI is included within Other Income (Expense) on the Company's condensed consolidated statement of income. CGT and SCI operated principally in wholesale markets, whereas the Company's primary focus is the delivery of energy-related products and services to retail markets. In addition, neither CGT nor SCI met accounting criteria for disclosure as a reportable segment and were included within the All Other caption in Note 10. The sales of CGT and SCI did not represent a strategic shift that had a major effect on the Company's operations; therefore, these sales did not meet the criteria for classification as discontinued operations. |
New Accounting Pronouncements, Policy [Policy Text Block] | New Accounting Matters In May 2014, the FASB issued accounting guidance for revenue arising from contracts with customers that supersedes most earlier revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized, and will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2018. The guidance permits adoption using a retrospective method, with options to elect certain practical expedients, or recognition of a cumulative effect in the year of initial adoption. The Company and Consolidated SCE&G have not determined which method of adoption will be employed or what practical expedients may be elected. The Company and Consolidated SCE&G have not determined the impact this guidance will have on their respective financial statements. However, the identification of implementation project team members and the analysis of contracts with customers to which the guidance might be applicable, particularly large customer contracts, have begun. In July 2015, the FASB issued accounting guidance intended to simplify the subsequent measurement of inventory cost by requiring most inventory to be measured at the lower of cost and net realizable value. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2017 and have determined that the adoption of this guidance will not have a significant impact on their respective financial statements. In January 2016, the FASB issued accounting guidance that will change how entities measure certain equity investments and financial liabilities, among other things. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2018. The Company and Consolidated SCE&G are evaluating this guidance and do not anticipate that its adoption will have a significant impact on their respective financial statements. In February 2016, the FASB issued accounting guidance related to the recognition, measurement and presentation of leases. The guidance applies a right-of-use model and, for lessees, requires all leases with a duration over 12 months to be recorded on the balance sheet, with the rights of use treated as assets and the payment obligations treated as liabilities. Further, and without consideration of any regulatory accounting requirements which may apply, depending primarily on the nature of the assets and the relative consumption of them, lease costs will be recognized either through the separate amortization of the right-of-use asset and the recognition of the interest cost related to the payment obligation, or through the recording of a combined straight-line rental expense. For lessors, the guidance calls for the recognition of income either through the derecognition of assets and subsequent recording of interest income on lease amounts receivable, or through the recognition of rental income on a straight-line basis, also depending on the nature of the assets and relative consumption. The guidance will be effective for years beginning in 2019. The Company and Consolidated SCE&G have not determined what impact this guidance will have on their respective financial statements. However, the identification of implementation project team members and the initial identification and analysis of leasing and related contracts to which the guidance might be applicable have begun. In March 2016, the FASB issued accounting guidance changing how companies account for certain aspects of share-based payments to employees. Entities will be required to recognize the income tax effects of awards in the income statement when the awards vest or are settled. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2017. The Company and Consolidated SCE&G are evaluating this guidance and, based on the nature of their current share-based awards practices, do not anticipate that its adoption will have a significant impact on their respective financial statements. In June 2016, the FASB issued accounting guidance requiring the use of a current expected credit loss impairment model for certain financial instruments. The new model is applicable to trade receivables and most debt instruments, among other financial instruments, and is intended to result in impairment losses being recognized earlier than under current guidance. The Company and Consolidated SCE&G must adopt this guidance beginning in 2020, including interim periods, though the guidance may be adopted in 2019. The Company and Consolidated SCE&G have not determined when this guidance will be adopted or what impact it will have on their respective financial statements. In August 2016, the FASB issued accounting guidance to reduce diversity in cash flow classification related to certain transactions. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2018 and do not anticipate that its adoption will impact their respective financial statements. |

Basis Of Consolidation And Variable Interest Entities [Policy Text Block] | Basis of Consolidation and Variable Interest Entities The condensed consolidated financial statements of the Company include, after eliminating intercompany balances and transactions, the accounts of the parent holding company and each of its subsidiaries, including Consolidated SCE&G. Accordingly, discussions regarding the Company's financial results necessarily include the results of Consolidated SCE&G. SCE&G has determined that it has a controlling financial interest in GENCO and Fuel Company (which are considered to be VIEs) and, accordingly, Consolidated SCE&G's condensed consolidated financial statements include the accounts of SCE&G, GENCO and Fuel Company. The equity interests in GENCO and Fuel Company are held solely by SCANA, SCE&G’s parent. As a result, GENCO’s and Fuel Company’s equity and results of operations are reflected as noncontrolling interest in Consolidated SCE&G’s condensed consolidated financial statements. GENCO owns a coal-fired electric generating station with a 605 MW net generating capacity (summer rating). GENCO’s electricity is sold, pursuant to a FERC-approved tariff, solely to SCE&G under the terms of a power purchase agreement and related operating agreement. The effects of these transactions are eliminated in consolidation. Substantially all of GENCO’s property (carrying value of approximately $483 million ) serves as collateral for its long-term borrowings. Fuel Company acquires, owns and provides financing for SCE&G’s nuclear fuel, certain fossil fuels and emission and other environmental allowances. See also Note 4. |
Income Statement policy [Policy Text Block] | Income Statement Presentation Revenues and expenses arising from regulated businesses and, in the case of the Company, retail natural gas marketing businesses (including those activities of segments described in Note 10) are presented within Operating Income, and all other activities are presented within Other Income (Expense). Consistent with this presentation, the Company presents the 2015 gain on the sale of CGT within Operating Income and the 2015 gain on the sale of SCI within Other Income (Expense). |
New Accounting Pronouncements, Policy [Policy Text Block] | New Accounting Matters In May 2014, the FASB issued accounting guidance for revenue arising from contracts with customers that supersedes most earlier revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized, and will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2018. The guidance permits adoption using a retrospective method, with options to elect certain practical expedients, or recognition of a cumulative effect in the year of initial adoption. The Company and Consolidated SCE&G have not determined which method of adoption will be employed or what practical expedients may be elected. The Company and Consolidated SCE&G have not determined the impact this guidance will have on their respective financial statements. However, the identification of implementation project team members and the analysis of contracts with customers to which the guidance might be applicable, particularly large customer contracts, have begun. In July 2015, the FASB issued accounting guidance intended to simplify the subsequent measurement of inventory cost by requiring most inventory to be measured at the lower of cost and net realizable value. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2017 and have determined that the adoption of this guidance will not have a significant impact on their respective financial statements. In January 2016, the FASB issued accounting guidance that will change how entities measure certain equity investments and financial liabilities, among other things. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2018. The Company and Consolidated SCE&G are evaluating this guidance and do not anticipate that its adoption will have a significant impact on their respective financial statements. In February 2016, the FASB issued accounting guidance related to the recognition, measurement and presentation of leases. The guidance applies a right-of-use model and, for lessees, requires all leases with a duration over 12 months to be recorded on the balance sheet, with the rights of use treated as assets and the payment obligations treated as liabilities. Further, and without consideration of any regulatory accounting requirements which may apply, depending primarily on the nature of the assets and the relative consumption of them, lease costs will be recognized either through the separate amortization of the right-of-use asset and the recognition of the interest cost related to the payment obligation, or through the recording of a combined straight-line rental expense. For lessors, the guidance calls for the recognition of income either through the derecognition of assets and subsequent recording of interest income on lease amounts receivable, or through the recognition of rental income on a straight-line basis, also depending on the nature of the assets and relative consumption. The guidance will be effective for years beginning in 2019. The Company and Consolidated SCE&G have not determined what impact this guidance will have on their respective financial statements. However, the identification of implementation project team members and the initial identification and analysis of leasing and related contracts to which the guidance might be applicable have begun. In March 2016, the FASB issued accounting guidance changing how companies account for certain aspects of share-based payments to employees. Entities will be required to recognize the income tax effects of awards in the income statement when the awards vest or are settled. The Company and Consolidated SCE&G expect to adopt this guidance when required in the first quarter of 2017. The Company and Consolidated SCE&G are evaluating this guidance and, based on the nature of their current share-based awards practices, do not anticipate that its adoption will have a significant impact on their respective financial statements. In June 2016, the FASB issued accounting guidance requiring the use of a current expected credit loss impairment model for certain financial instruments. The new model is applicable to trade receivables and most debt instruments, among other financial instruments, and is intended to result in impairment losses being recognized earlier than under current guidance.
