Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Nature of Operations : American States Water Company (“AWR”) is the parent company of Golden State Water Company (“GSWC”), Bear Valley Electric Service, Inc. (“BVES”), and American States Utility Services, Inc. (“ASUS”) (and its wholly owned subsidiaries: Fort Bliss Water Services Company (“FBWS”), Terrapin Utility Services, Inc. (“TUS”), Old Dominion Utility Services, Inc. (“ODUS”), Palmetto State Utility Services, Inc. (“PSUS”), Old North Utility Services, Inc. (“ONUS”), Emerald Coast Utility Services, Inc. (“ECUS”), and Fort Riley Utility Services, Inc. (“FRUS”)). The subsidiaries of ASUS are collectively referred to as the “Military Utility Privatization Subsidiaries.” AWR, through its wholly owned subsidiaries, serves over one million people in nine states. GSWC and BVES are both California public utilities. GSWC is engaged in the purchase, production, distribution and sale of water throughout California serving approximately 263,600 customer connections. BVES distributes electricity in several San Bernardino County mountain communities in California serving approximately 24,700 customer connections. The California Public Utilities Commission (“CPUC”) regulates GSWC’s and BVES’s businesses in matters including properties, rates, services, facilities, and transactions between GSWC, BVES, and their affiliates. ASUS, through its wholly owned subsidiaries, operates, maintains and performs construction activities (including renewal and replacement capital work) on water and/or wastewater systems at various U.S. military bases pursuant to initial 50-year firm fixed-price contracts. These contracts are subject to annual economic price adjustments and modifications for changes in circumstances, changes in laws and regulations, and additions to the contract value for new construction of facilities at the military bases. There is no direct regulatory oversight by the CPUC over AWR or the operations, rates or services provided by ASUS or any of its wholly owned subsidiaries. Basis of Presentation : The consolidated financial statements and notes hereto are presented in a combined report filed by two separate Registrants: AWR and GSWC. References in this report to “Registrant” are to AWR and GSWC, collectively, unless otherwise specified. AWR owns all of the outstanding common shares of GSWC, BVES and ASUS. ASUS owns all of the outstanding common stock of the Military Utility Privatization Subsidiaries. The consolidated financial statements of AWR include the accounts of AWR and its subsidiaries. These financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Intercompany transactions and balances have been eliminated in the AWR consolidated financial statements. The consolidated financial statements included herein have been prepared by Registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The December 31, 2022 condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. In the opinion of management, all adjustments consisting of normal, recurring items, and estimates necessary for a fair statement of the results for the interim periods have been made. It is suggested that these consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Form 10-K for the year ended December 31, 2022 filed with the SEC. Related Party and Intercompany Transactions : As discussed below under Liquidity and Financing Activities , prior to AWR and GSWC entering into new separate credit agreements on June 28, 2023 that replaced AWR's previous credit agreement, AWR borrowed under its credit facility and provided funds to both GSWC and ASUS in support of their operations. Under AWR's new credit facility, AWR borrows and continues to provide funds to ASUS in support of their operations. GSWC's new credit facility provides support for its water operations. Furthermore, GSWC, BVES and ASUS provide and/or receive various support services to and from their parent, AWR, and among themselves. GSWC has allocated certain corporate office administrative and general costs to its affiliates, BVES and ASUS, using allocation factors approved by the CPUC. GSWC allocated corporate office administrative and general costs to the electric segment of approximately $745,000 and $592,000 during the three months ended June 30, 2023 and 2022, respectively, and $2.1 million and $1.4 million during the six month periods ended June 30, 2023 and 2022. GSWC allocated corporate office administrative and general costs to ASUS of approximately $1.2 million and $1.1 million during the three months ended June 30, 2023 and 2022, respectively, and $2.7 million during each of the six months ended June 30, 2023 and 2022. In January 2023, the Board of Directors approved the issuance of one GSWC Common Share to AWR for $10.0 million. In January 2023, GSWC also issued $130.0 million in unsecured private placement long-term notes. GSWC used the proceeds from both the issuance of equity and long-term debt to pay-off all intercompany borrowings from AWR. On June 28, 2023, GSWC borrowed for the first time under its new syndicated credit facility and used the proceeds to again pay-off in full its short-term intercompany borrowings due to AWR. The CPUC requires GSWC to fully pay-off all intercompany borrowings it has from AWR within a 24-month period. GSWC's borrowings under its new credit facility will also be required to be paid-off in full within a 24-month period. Liquidity and Financing Activities : On June 28, 2023, AWR and GSWC, each entered into new credit agreements with a term of five years provided by a syndicate of banks and financial institutions. Both credit agreements will mature on June 28, 2028. In connection with the new credit agreements, AWR and GSWC paid upfront, legal and other fees totaling $530,000 and $702,000, respectively. The syndicated credit facilities replaced AWR’s previous credit agreement with a sole bank where AWR had a borrowing capacity of $280.0 million to support both GSWC and ASUS operations. Funds from the new facilities were used to pay-off in full all outstanding borrowings under AWR's prior credit facility and GSWC's outstanding intercompany borrowings from AWR. AWR’s credit agreement provides for a $150.0 million unsecured revolving credit facility to support AWR parent and ASUS. Under AWR’s credit agreement, the borrowing capacity may be expanded up to an additional amount of $75.0 million subject to the lenders’ approval. The aggregate amount that may be outstanding under letters of credit is $10.0 million. Loans may be obtained under this credit facility at the option of AWR and bear interest at rates based on either a base rate plus an applicable margin or an adjusted term secured overnight financing rate (“SOFR”) determined by the SOFR administrator, currently the Federal Reserve Bank of New York, plus an applicable margin. The applicable margin depends upon AWR’s credit rating. AWR's outstanding borrowings under the credit facility of $135.0 million as of June 30, 2023 have been classified as non-current liabilities on AWR’s Consolidated Balance Sheet. AWR’s credit agreement contains affirmative and negative covenants and events of default customary for credit facilities of this type, including, among other things, affirmative covenants relating to compliance with law and material contracts, and negative covenants relating to additional indebtedness, liens, investments, restricted payments and asset sales by AWR and its subsidiaries, other than BVES. AWR is not permitted to have a consolidated total capitalization ratio (consolidated funded indebtedness to sum of shareholders’ equity and consolidated funded indebtedness), excluding AWR’s electric subsidiary, greater than 0.65 to 1.00 at the end of any quarter. Default under any indebtedness of any subsidiary of AWR, other than BVES, will result in a default under AWR’s credit agreement. GSWC’s credit agreement provides for a $200.0 million unsecured revolving credit facility to support its operations and capital expenditures. Under GSWC’s credit agreement, the borrowing capacity may be expanded up to an additional amount of $75.0 million, subject to the lenders’ approval. The aggregate amount that may be outstanding under letters of credit is $20.0 million. Loans may be obtained under this credit facility at the option of GSWC and bear interest at rates based on either a base rate plus an applicable margin or an adjusted term SOFR determined by the SOFR administrator plus an applicable margin. The applicable margin depends upon GSWC’s credit rating. GSWC's outstanding borrowings under the credit facility of $78.0 million as of June 30, 2023 have been classified as non-current liabilities on GSWC’s Balance Sheet. Similar to AWR's credit agreement, GSWC's credit agreement also contains affirmative and negative covenants and events of default customary for credit facilities of its type. GSWC is also not permitted to have a total capitalization ratio greater than 0.65 to 1.00 at the end of any quarter. Default under any indebtedness of any subsidiary of AWR will not result in a default under GSWC’s credit agreement. On June 16, 2023, BVES’s credit agreement was amended to increase the borrowing capacity from $35.0 million to $50.0 million. In addition, BVES’s amended credit agreement also (i) extends the credit facility to July 1, 2026, (ii) converts the interest rate on new borrowings to the benchmark rate of SOFR, plus a margin, and (iii) provides an option to increase the facility by an additional $25.0 million, subject to lender approval. Based on the amended terms of the credit agreement, the outstanding borrowings under the credit facility of $30.0 million as of June 30, 2023 have been classified as a non-current liability in AWR’s Consolidated Balance Sheet. Borrowings made under this facility will continue to be used to support the electric segment's operations and capital expenditures.

Revenues

Revenue from Contract with Customer [Abstract]
Revenues	Revenues Most of Registrant’s revenues are derived from contracts with customers, including tariff-based revenues from its regulated utilities at GSWC and BVES. ASUS’s initial 50-year firm fixed-price contracts with the U.S. government are considered service concession arrangements under ASC 853, Service Concession Arrangements . Accordingly, the services under these contracts are accounted for under Topic 606 —Revenue from Contracts with Customers, and the water and/or wastewater systems are not recorded as Property, Plant and Equipment on Registrant’s balance sheets. Although GSWC and BVES have a diversified customer base of residential, commercial, industrial, and other customers, revenues derived from residential and commercial customers generally account for approximately 90% of total water and electric revenues. Most of ASUS’s revenues are derived from the U.S. government. For the three and six months ended June 30, 2023 and 2022, disaggregated revenues from contracts with customers by segment were as follows: Three Months Ended June 30, Six Months Ended June 30, (dollars in thousands) 2023 2022 2023 2022 Water: Tariff-based revenues $ 98,378 $ 83,612 $ 198,919 $ 156,110 Surcharges (cost-recovery activities) 558 797 875 1,346 Other 649 571 1,386 1,089 Water revenues from contracts with customers 99,585 84,980 201,180 158,545 WRAM under-collection (alternative revenue program) 17,323 5,876 28,440 6,217 Total water revenues (1) 116,908 90,856 229,620 164,762 Electric: Tariff-based revenues 8,929 8,381 21,992 20,933 Surcharges (cost-recovery activities) 117 32 266 59 Electric revenues from contracts with customers 9,046 8,413 22,258 20,992 BRRAM over-collection (alternative revenue program) (218) (196) (526) (883) Total electric revenues 8,828 8,217 21,732 20,109 Contracted services: Water 19,181 14,175 41,669 27,721 Wastewater 12,483 9,359 25,802 18,585 Contracted services revenues from contracts with customers 31,664 23,534 67,471 46,306 Total AWR revenues $ 157,400 $ 122,607 $ 318,823 $ 231,177 (1) Water revenues for the six months ended June 30, 2023 includes approximately $30 million from the impact of retroactive new rates for the full year of 2022 as a result of the CPUC's approval of GSWC's general rate case (Note 3). Furthermore, the CPUC also issued a final decision in June 2023 on GSWC's cost of capital proceeding. As a result of the final cost of capital decision (Note 3), the three and six months ended June 30, 2023 include an increase in water revenues of $9.3 million and $6.4 million, respectively, from the reversal of revenues subject to refund due to a change in estimates from what had been recorded during 2022 and the first quarter of 2023. The opening and closing balances of the receivable from the U.S. government, contract assets, and contract liabilities from contracts with customers, which are related entirely to ASUS, were as follows: (dollars in thousands) June 30, 2023 December 31, 2022 Unbilled receivables $ 11,629 $ 10,125 Receivable from the U.S. government $ 96,378 $ 85,456 Contract assets $ 15,510 $ 14,982 Contract liabilities $ 585 $ 903 Unbilled receivables and Receivable from the U.S. government represent receivables where the right to payment is conditional only by the passage of time. Contract Assets - Contract assets are assets of ASUS and consist of unbilled revenues recognized from work-in-progress construction projects, where the right to payment is conditional on something other than the passage of time. The classification of this asset as current or noncurrent is based on the timing of when ASUS expects to bill these amounts. Contract Liabilities - Contract liabilities are liabilities of ASUS and consist of billings in excess of revenue recognized. The classification of this liability as current or noncurrent is based on the timing of when ASUS expects to recognize revenue. Revenues for the three and six months ended June 30, 2023, which were included in contract liabilities at the beginning of the period were not material. Contracted services revenues recognized during the three and six months ended June 30, 2023 from performance obligations satisfied in previous periods were also not material. As of June 30, 2023, AWR’s aggregate remaining performance obligations, which are entirely from the contracted services segment, were $3.6 billion. ASUS expects to recognize revenue on these remaining performance obligations over the remaining term of each of the 50-year contracts, which range from 31 to 45 years. Each of the contracts with the U.S. government is subject to termination, in whole or in part, prior to the end of its 50-year term for convenience of the U.S. government.

Regulatory Matters

Regulatory Matters	6 Months Ended

Regulated Operations [Abstract]
Regulatory Matters	Regulatory Matters In accordance with accounting principles for rate-regulated enterprises, GSWC and BVES record regulatory assets, which represent probable future recovery of incurred costs from customers through the ratemaking process, and regulatory liabilities, which represent probable future refunds that are to be credited to customers through the ratemaking process. At June 30, 2023, GSWC and BVES had approximately $73.7 million of regulatory liabilities, net of regulatory assets, not accruing carrying costs. Of this amount, (i) $74.9 million of regulatory liabilities are excess deferred income taxes arising from the lower federal income tax rate under the Tax Cuts and Jobs Act enacted in December 2017 that are being refunded to customers, (ii) $2.4 million of net regulatory assets relates to the underfunded position in Registrant's pension and other retirement obligations (not including the two-way pension balancing accounts), and (iii) a $4.7 million regulatory liability related to a memorandum account authorized by the CPUC to track unrealized gains and losses on BVES’s purchase power contracts over the term of the contracts. The remainder relates to other items that do not provide for or incur carrying costs including flowed-through deferred income taxes. Regulatory assets represent costs incurred by GSWC and/or BVES for which they have received or expect to receive rate recovery in the future. In determining the probability of costs being recognized in other periods, GSWC and BVES consider regulatory rules and decisions, past practices, and other facts or circumstances that would indicate if recovery is probable. If the CPUC determines that a portion of either GSWC’s or BVES’s regulatory assets are not recoverable in customer rates, the applicable utility must determine if it has suffered an asset impairment that requires it to write down the asset’s value. Regulatory assets are offset against regulatory liabilities within each ratemaking area. Amounts expected to be collected or refunded in the next twelve months have been classified as current assets and current liabilities by ratemaking area. Regulatory assets, less regulatory liabilities, included in the consolidated balance sheets are as follows: (dollars in thousands) June 30, December 31, GSWC 2022/2023 general rate case memorandum accounts (unbilled revenue) $ 50,345 $ — Water revenue adjustment mechanism, net of modified cost balancing account 39,006 31,803 COVID-19 memorandum accounts 3,543 3,478 Excess deferred income taxes (70,967) (71,870) Other regulatory assets 24,917 19,964 Other regulatory liabilities (2,039) (9,949) Total GSWC $ 44,805 $ (26,574) BVES Derivative instrument memorandum account (Note 5) (4,657) (11,847) Wildfire mitigation and other fire prevention related costs memorandum accounts 15,121 13,007 Other regulatory assets 9,546 7,965 Other regulatory liabilities (8,505) (8,005) Total AWR $ 56,310 $ (25,454) Regulatory matters are discussed in the consolidated financial statements and the notes thereto included in the Company’s Form 10-K for the year ended December 31, 2022 filed with the SEC. The discussion below focuses on significant matters and developments since December 31, 2022. Water General Rate Case and the 2022/2023 General Rate Case Memorandum Accounts: On June 29, 2023, the CPUC adopted a final decision in GSWC's general rate case application for all of its water regions and its general office that determines new water rates for the years 2022–2024. The assigned administrative law judge at the CPUC had issued a proposed decision on April 13, 2023 that, among other things, (i) adopted the full settlement agreement between GSWC and the Public Advocates Office at the CPUC (“Public Advocates”) that resolved all issues related to the 2022 annual revenue requirement in the general rate case application, and (ii) allowed for additional increases in adopted revenues for 2023 and 2024 subject to an earnings test and inflationary index values at the time of filing for implementation of the new rates. The final decision issued on June 29, 2023 is consistent in all material respects with the proposed decision issued in April. The new rates for 2022 and 2023 are effective and retroactive to January 1, 2022 and January 1, 2023, respectively. The impact of retroactive rates for the full year of 2022 as well as the 2023 second-year rate increases for the first half of 2023 have been reflected in the results of operations for the six months ended June 30, 2023 . Because of receiving a proposed decision in April 2023 that approved the settlement agreement in its entirety, the impact of retroactive rates for the full year of 2022 and the estimated second-year rate increases had been reflected in the 2023 first quarter results as it became probable that the approved retroactive rates for the full year of 2022 and the first three months of 2023 would be permitted to be billed to customers in the future. Due to the delay in finalizing the water general rate case, water revenues billed to customers for the year ended December 31, 2022 and for the six months ended June 30, 2023 were based on 2021 adopted rates. GSWC was authorized to create general rate case memorandum accounts to track the revenue differences between the 2021 adopted rates and the new 2022 and 2023 rates authorized by the CPUC. As of June 30, 2023, there is an aggregate cumulative amount of $50.3 million in the general rate case memorandum accounts that have been recorded as regulatory assets related to unbilled water revenues recognized during the three and six months ended June 30, 2023, and which represent the difference between the 2021 adopted rates billed to customers and the rates authorized in the final decision for the full year of 2022 and the 2023 second-year rate increases recorded through June 30, 2023. As a result of receiving the final decision, GSWC filed for the implementation of new 2023 rate increases that went into effect on July 31, 2023. Within 90 days after the implementation of 2023 rates, GSWC will also file to recover all retroactive amounts accumulated in GSWC's general rate case memorandum accounts, of which the majority of the balances will be recovered over a 36-month period. Alternative-Revenue Programs: GSWC currently records the difference between what it bills its water customers and that which is authorized by the CPUC using the Water Revenue Adjustment Mechanism (“WRAM”) and the Modified Cost Balancing Account (“MCBA”) approved by the CPUC. The over- or under-collection of the WRAM is aggregated with the MCBA over- or under-collection for the corresponding ratemaking area and bears interest at the current 90-day commercial-paper rate. As of June 30, 2023, GSWC had an aggregated regulatory asset of $39.0 million, which is comprised of a $43.4 million under-collection in the WRAM accounts and a $4.4 over-collection in the MCBA accounts. During the six months ended June 30, 2023, GSWC recorded additional net under-collections in the WRAM/MCBA accounts of approximately $22.2 million related to the 2023 year that resulted largely from lower-than-adopted water usage as authorized in the general rate case decision. In addition, GSWC recorded a net reduction of $9.8 million of under-collections during the first quarter of 2023 to reflect the cumulative full-year impact of 2022 based on authorized 2022 amounts approved in the general rate case decision for both the WRAM and MCBA accounts. On July 27, 2023, the CPUC approved the recovery of all pre-2023 WRAM/MCBA balances. Accordingly, GSWC has implemented surcharges and surcredits to recover/refund all of its WRAM/MCBA balances accumulated as of December 31, 2022. As required by the accounting guidance for alternative revenue programs, GSWC is required to collect its WRAM balances within 24 months following the year in which an under-collection is recorded. As of June 30, 2023, there were no WRAM under-collections that were estimated to be collected beyond this 24 month period. Cost of Capital Proceeding: O n June 29, 2023, a final decision was adopted by the CPUC in the cost of capital proceeding that, among other things, (i) adopts GSWC’s requested capital structure of 57% equity and 43% debt; (ii) adopts a cost of debt of 5.1% for GSWC as compared to 6.6% previously authorized; (iii) adopts a return on equity of 8.85% for GSWC as compared to 8.9% previously authorized; (iv) allows for the continuation of the Water Cost of Capital Mechanism (“WCCM”) through December 31, 2024; and (v) adopts the new cost of capital for the three Following the receipt of the final decision adopted on June 29 in the cost of capital proceeding, management updated its analysis and reassessed the accounting estimates recorded to date related to GSWC’s lower cost of debt. Accordingly, GSWC recorded a change in estimate that resulted in an increase to water revenues during the second quarter of 2023 in the amount of $9.3 million as a result of reversing its regulatory liability for revenues subject to refund that it had recorded during 2022 and through the end of the first quarter of 2023. The lower revenues recorded in 2022 and in the first quarter of 2023 of $6.4 million and $2.9 million, respectively, were estimates of revenues subject to refund at that time associated with the lower cost of debt. The WCCM adjusts the return on equity and rate of return on rate base between the three COVID-19 Emergency Memorandum Accounts : The CPUC has authorized GSWC and BVES to track incremental costs, including bad debt expense, in excess of what is included in their respective revenue requirements incurred as a result of the pandemic in COVID-19 emergency-related memorandum accounts. As of June 30, 2023, GSWC and BVES had approximately $3.5 million and $500,000, respectively, in regulatory asset accounts related to bad debt expense in excess of their revenue requirements, the purchase of personal protective equipment, additional incurred printing costs, and other incremental COVID-19-related costs, which GSWC and BVES intend to file with the CPUC for future recovery. Emergency-related memorandum accounts are well-established cost recovery mechanisms authorized as a result of a state/federal declared emergency, and are therefore recognized as regulatory assets for future recovery. As a result, the amounts recorded in the COVID-19 emergency-related memorandum accounts have not impacted GSWC’s or BVES’s earnings. On April 10, 2023, the Biden Administration terminated the COVID-19 national emergency. The COVID-19 emergency-related memorandum accounts for GSWC and BVES expired when the COVID-19 national emergency ended and no additional amounts will be included in these memorandum accounts. The CPUC requires that amounts tracked in GSWC’s and BVES’s COVID-19 memorandum accounts for unpaid customer bills be first offset by any (i) federal and state relief for water or electric utility bill debt, and (ii) customer payments through payment plan arrangements, prior to receiving recovery from customers at large. After these offsets are made, GSWC will file with the CPUC for recovery of the remaining balance. BVES intends to include the remaining balance in its COVID-19 memorandum account for recovery once all alternative sources of funding have been exhausted and credited to eligible customer accounts. In 2022, the CPUC’s moratoriums on service disconnections for nonpayment for water and electric customers ended. As a result, service disconnections due to nonpayment resumed with disconnections for delinquent residential customers having resumed in June 2022. BVES Regulatory Assets: Wildfire Mitigation and Other Fire Prevention Related Costs Memorandum Accounts The CPUC adopted regulations intended to enhance the fire safety of overhead electric power lines. Those regulations included increased minimum clearances around electric power lines. BVES was authorized to track incremental costs incurred to implement the regulations in a fire hazard prevention memorandum account for the purpose of obtaining cost recovery in a future general rate case. In August 2019, the CPUC issued a final decision on the electric general rate case, which set new rates for BVES through the year 2022. Among other things, the decision authorized BVES to record incremental costs related to vegetation management, such as costs for increased minimum clearances around electric power lines, in the CPUC-approved memorandum account for future recovery. As of June 30, 2023, BVES had approximately $10.1 million in incremental vegetation management costs recorded as a regulatory asset, which has been included in a new general rate case application filed with the CPUC in August 2022 for future recovery. The incremental costs related to vegetation management included in the memorandum account will be subject to review during the pending general rate case proceeding. California legislation enacted in September 2018 requires all investor-owned electric utilities to submit an annual wildfire mitigation plan (“WMP”) to the CPUC for approval. The WMP must include a utility’s plans on constructing, maintaining and operating its electrical lines and equipment to minimize the risk of catastrophic wildfire. In December 2022, the Office of Energy Infrastructure Safety under the California Natural Resources Agency approved BVES's 2022 WMP update. In February 2023, the CPUC ratified BVES’s current WMP. As of June 30, 2023, BVES has approximately $5.0 million related to expenses accumulated in its WMP memorandum accounts that have been recognized as regulatory assets for future recovery. All capital expenditures and other costs incurred through June 30, 2023 as a result of BVES’s WMPs are not currently in rates and have been filed for future recovery in BVES’s general rate case application. These costs will be subject to review during BVES's general rate case proceeding. 2023 Winter Storm Other Regulatory Asset BVES activated a catastrophic emergency memorandum account (“CEMA”) to track the incremental costs incurred in response to a severe winter storm that occurred during certain weeks of the first and second quarters of 2023, which resulted in the declaration of an emergency by the governor of California. Incremental costs of approximately $1.3 million were incurred and included in the CEMA account, which has been recorded as a regulatory asset as of June 30, 2023 for future recovery. The incremental costs included in the CEMA account will be subject to review and approval by the CPUC. CEMA accounts are well-established cost recovery mechanisms authorized as a result of a state/federal declared emergency, and are therefore recognized as regulatory assets for future recovery. As a result, the amounts recorded in this CEMA account did not impact BVES’s earnings. Other Regulatory Assets :

Earnings Per Share [Abstract]
Earnings per Share/Capital Stock	Earnings per Share/Capital Stock In accordance with the accounting guidance for participating securities and earnings per share (“EPS”), Registrant uses the “two-class” method of computing EPS. The “two-class” method is an earnings allocation formula that determines EPS for each class of common stock and participating security. AWR has participating securities related to restricted stock units that earn dividend equivalents on an equal basis with AWR’s Common Shares, and that have been issued under AWR’s stock incentive plans for employees and the non-employee directors stock plans. In applying the “two-class” method, undistributed earnings are allocated to both common shares and participating securities. The following is a reconciliation of Registrant’s net income and weighted average Common Shares outstanding used for calculating basic net income per share: Basic: For The Three Months Ended For The Six Months Ended (in thousands, except per share amounts) 2023 2022 2023 2022 Net income $ 38,521 $ 19,951 $ 72,928 $ 34,113 Less: (a) Distributed earnings to common shareholders 14,698 13,489 29,394 26,974 Distributed earnings to participating securities 43 36 80 67 Undistributed earnings 23,780 6,426 43,454 7,072 (b) Undistributed earnings allocated to common shareholders 23,711 6,409 43,337 7,055 Undistributed earnings allocated to participating securities 69 17 117 17 Total income available to common shareholders, basic (a)+(b) $ 38,409 $ 19,898 $ 72,731 $ 34,029 Weighted average Common Shares outstanding, basic 36,976 36,956 36,972 36,950 Basic earnings per Common Share $ 1.04 $ 0.54 $ 1.97 $ 0.92 Diluted EPS is based upon the weighted average number of Common Shares, including both outstanding shares and shares potentially issuable in connection with restricted stock units granted under AWR’s stock incentive plans for employees and directors, and net income. There were no stock options outstanding as of June 30, 2023 and 2022 under these plans. At June 30, 2023 and 2022, there were 110,576 and 100,820 restricted stock units outstanding, respectively, including performance shares awarded to officers of the Company. The following is a reconciliation of Registrant’s net income and weighted average Common Shares outstanding for calculating diluted net income per share: Diluted: For The Three Months Ended For The Six Months Ended (in thousands, except per share amounts) 2023 2022 2023 2022 Common shareholders earnings, basic $ 38,409 $ 19,898 $ 72,731 $ 34,029 Undistributed earnings for dilutive stock-based awards 69 17 117 17 Total common shareholders earnings, diluted $ 38,478 $ 19,915 $ 72,848 $ 34,046 Weighted average common shares outstanding, basic 36,976 36,956 36,972 36,950 Stock-based compensation (1) 91 83 86 79 Weighted average common shares outstanding, diluted 37,067 37,039 37,058 37,029 Diluted earnings per Common Share $ 1.04 $ 0.54 $ 1.97 $ 0.92 (1) All of the 110,576 and 100,820 restricted stock units at June 30, 2023 and 2022, respectively, were included in the calculation of diluted EPS for the three and six months ended June 30, 2023 and 2022. During the six months ended June 30, 2023 and 2022, AWR issued 14,358 and 19,742 of common shares related to restricted stock units, respectively. During the six months ended June 30, 2023 and 2022, AWR paid $899,000 and $1.2 million, respectively, to taxing authorities on employees’ behalf for shares withheld related to net share settlements. During the six months ended June 30, 2023 and 2022, GSWC paid $821,000 and $1.1 million, respectively, to taxing authorities on employees’ behalf for shares withheld related to net share settlements. These payments are included in the stock-based compensation caption of the statements of equity. During the three months ended June 30, 2023 and 2022, AWR paid quarterly dividends of approximately $14.7 million, or $0.3975 per share, and $13.5 million, or $0.3650 per share, respectively. During the six months ended June 30, 2023 and 2022, AWR paid quarterly dividends of approximately $29.4 million, or $0.7950 per share, and $27.0 million, or $0.7300 per share, respectively. During the six months ended June 30, 2023, GSWC issued one Common Share to AWR for $10.0 million. Proceeds from the stock issuance were used to pay down a portion of intercompany borrowings owed to AWR as described in Note 1. During the three months ended June 30, 2023 and 2022, GSWC paid dividends of $14.7 million and $13.5 million, respectively, to AWR. During the six months ended June 30, 2023 and 2022, GSWC paid dividends of $39.4 million and $27.0 million, respectively, to AWR.

Derivative Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments BVES has purchased power under long-term contracts at a fixed cost over three five Among other things, the CPUC authorized the use of a regulatory asset and liability memorandum account to offset the mark-to-market entries required by the accounting guidance. Accordingly, all unrealized gains and losses generated from the purchased power contracts are deferred on a monthly basis into a non-interest-bearing regulatory memorandum account that tracks the changes in fair value of the derivative throughout the terms of the contracts. As a result, these unrealized gains and losses did not impact Registrant’s earnings. As of June 30, 2023, there was a $4.7 million purchase power contract derivative asset at fair value, with a corresponding regulatory liability recorded in the derivative instrument memorandum account as a result of fixed prices under BVES's purchase power contracts being lower than future energy prices. The notional volume of derivatives remaining under these long-term contracts as of June 30, 2023 was 157,571 megawatt hours. The accounting guidance for fair value measurements applies to all financial assets and financial liabilities that are measured and reported on a fair value basis. Under the accounting guidance, Registrant has made fair value measurements that are classified and disclosed in one of the following three categories: Level 1 : Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 : Quoted prices in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; or Level 3 : Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). To value the purchase power contracts, Registrant utilizes various inputs that include quoted market prices for energy over the duration of the contracts. The market prices used to determine the fair value for this derivative instrument were estimated based on independent sources such as broker quotes and publications that are not observable in or corroborated by the market. When such inputs have a significant impact on the measurement of fair value, the instruments are categorized as Level 3. Accordingly, the valuation of the derivatives on Registrant’s purchased power contract has been classified as Level 3 for all periods presented. The following table presents changes in the fair value of the Level 3 derivatives for the three and six months ended June 30, 2023 and 2022. The change in fair value was due to the change in market energy prices during the three and six months ended June 30, 2023 and 2022.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Environmental Clean-Up and Remediation at GSWC : GSWC has been involved in environmental remediation and cleanup at one of its plant sites that contained an underground storage tank which was used to store gasoline for its vehicles. This tank was removed from the ground in July 1990 along with the dispenser and ancillary piping. Since then, GSWC has been involved in various remediation activities at this site. Analysis indicates that off-site monitoring wells may be necessary to document effectiveness of remediation. As of June 30, 2023, the total amount spent to clean up and remediate GSWC’s plant facility was approximately $6.3 million, of which $1.5 million has been paid by the State of California Underground Storage Tank Fund. Amounts paid by GSWC have been included in rate base and approved by the CPUC for recovery. As of June 30, 2023, GSWC has a regulatory asset and an accrued liability for the estimated additional cost of $1.3 million to complete the cleanup at the site. The estimate includes costs for continued activities of groundwater cleanup and monitoring, future soil treatment and site-closure-related activities. The ultimate cost may vary as there are many unknowns in remediation of underground gasoline spills and this is an estimate based on currently available information. Management also believes it is probable that the estimated additional costs will continue to be approved in rate base by the CPUC. Contracted Services: ASUS’s utility privatization contract services are provided to the U.S. government pursuant to the terms of the initial 50-year firm, fixed-price contract and additional firm, fixed-price contracts subject to annual economic price adjustments. Entering into contracts with the U.S. government subjects ASUS to potential government audits or investigations of its business practices and compliance with government procurement statutes and regulations. ASUS had been under a civil government investigation over bidding and estimating practices used in certain capital upgrade projects and has fully cooperated with the investigation. In July 2023, ASUS and the U.S. government entered into an agreement that settles civil and monetary claims by the U.S. government. This settlement did not have a material impact on Registrant’s financial statements. Other Litigation: Registrant is also subject to other ordinary routine litigation incidental to its business, some of which may include claims for compensatory and punitive damages. Management believes that rate recovery, proper insurance coverage and reserves are in place to insure against, among other things, property, general liability, employment, and workers’ compensation claims incurred in the ordinary course of business. Insurance coverage may not cover certain claims involving punitive damages. Registrant does not believe the outcome from any pending suits or administrative proceedings will have a material effect on Registrant's consolidated results of operations, financial position, or cash flows.

Accounting Policies [Abstract]
Nature of Operations and Basis of Accounting	Nature of Operations : American States Water Company (“AWR”) is the parent company of Golden State Water Company (“GSWC”), Bear Valley Electric Service, Inc. (“BVES”), and American States Utility Services, Inc. (“ASUS”) (and its wholly owned subsidiaries: Fort Bliss Water Services Company (“FBWS”), Terrapin Utility Services, Inc. (“TUS”), Old Dominion Utility Services, Inc. (“ODUS”), Palmetto State Utility Services, Inc. (“PSUS”), Old North Utility Services, Inc. (“ONUS”), Emerald Coast Utility Services, Inc. (“ECUS”), and Fort Riley Utility Services, Inc. (“FRUS”)). The subsidiaries of ASUS are collectively referred to as the “Military Utility Privatization Subsidiaries.” AWR, through its wholly owned subsidiaries, serves over one million people in nine states. GSWC and BVES are both California public utilities. GSWC is engaged in the purchase, production, distribution and sale of water throughout California serving approximately 263,600 customer connections. BVES distributes electricity in several San Bernardino County mountain communities in California serving approximately 24,700 customer connections. The California Public Utilities Commission (“CPUC”) regulates GSWC’s and BVES’s businesses in matters including properties, rates, services, facilities, and transactions between GSWC, BVES, and their affiliates. ASUS, through its wholly owned subsidiaries, operates, maintains and performs construction activities (including renewal and replacement capital work) on water and/or wastewater systems at various U.S. military bases pursuant to initial 50-year firm fixed-price contracts. These contracts are subject to annual economic price adjustments and modifications for changes in circumstances, changes in laws and regulations, and additions to the contract value for new construction of facilities at the military bases. There is no direct regulatory oversight by the CPUC over AWR or the operations, rates or services provided by ASUS or any of its wholly owned subsidiaries. Basis of Presentation : The consolidated financial statements and notes hereto are presented in a combined report filed by two separate Registrants: AWR and GSWC. References in this report to “Registrant” are to AWR and GSWC, collectively, unless otherwise specified. AWR owns all of the outstanding common shares of GSWC, BVES and ASUS. ASUS owns all of the outstanding common stock of the Military Utility Privatization Subsidiaries. The consolidated financial statements of AWR include the accounts of AWR and its subsidiaries. These financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Intercompany transactions and balances have been eliminated in the AWR consolidated financial statements. The consolidated financial statements included herein have been prepared by Registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The December 31, 2022 condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. In the opinion of management, all adjustments consisting of normal, recurring items, and estimates necessary for a fair statement of the results for the interim periods have been made. It is suggested that these consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Form 10-K for the year ended December 31, 2022 filed with the SEC.
Related Party and Intercompany Transactions	Related Party and Intercompany Transactions : As discussed below under Liquidity and Financing Activities , prior to AWR and GSWC entering into new separate credit agreements on June 28, 2023 that replaced AWR's previous credit agreement, AWR borrowed under its credit facility and provided funds to both GSWC and ASUS in support of their operations. Under AWR's new credit facility, AWR borrows and continues to provide funds to ASUS in support of their operations. GSWC's new credit facility provides support for its water operations. Furthermore, GSWC, BVES and ASUS provide and/or receive various support services to and from their parent, AWR, and among themselves. GSWC has allocated certain corporate office administrative and general costs to its affiliates, BVES and ASUS, using allocation factors approved by the CPUC. GSWC allocated corporate office administrative and general costs to the electric segment of approximately $745,000 and $592,000 during the three months ended June 30, 2023 and 2022, respectively, and $2.1 million and $1.4 million during the six month periods ended June 30, 2023 and 2022. GSWC allocated corporate office administrative and general costs to ASUS of approximately $1.2 million and $1.1 million during the three months ended June 30, 2023 and 2022, respectively, and $2.7 million during each of the six months ended June 30, 2023 and 2022.
Liquidity and Financing Plans	Liquidity and Financing Activities : On June 28, 2023, AWR and GSWC, each entered into new credit agreements with a term of five years provided by a syndicate of banks and financial institutions. Both credit agreements will mature on June 28, 2028. In connection with the new credit agreements, AWR and GSWC paid upfront, legal and other fees totaling $530,000 and $702,000, respectively. The syndicated credit facilities replaced AWR’s previous credit agreement with a sole bank where AWR had a borrowing capacity of $280.0 million to support both GSWC and ASUS operations. Funds from the new facilities were used to pay-off in full all outstanding borrowings under AWR's prior credit facility and GSWC's outstanding intercompany borrowings from AWR. AWR’s credit agreement provides for a $150.0 million unsecured revolving credit facility to support AWR parent and ASUS. Under AWR’s credit agreement, the borrowing capacity may be expanded up to an additional amount of $75.0 million subject to the lenders’ approval. The aggregate amount that may be outstanding under letters of credit is $10.0 million. Loans may be obtained under this credit facility at the option of AWR and bear interest at rates based on either a base rate plus an applicable margin or an adjusted term secured overnight financing rate (“SOFR”) determined by the SOFR administrator, currently the Federal Reserve Bank of New York, plus an applicable margin. The applicable margin depends upon AWR’s credit rating. AWR's outstanding borrowings under the credit facility of $135.0 million as of June 30, 2023 have been classified as non-current liabilities on AWR’s Consolidated Balance Sheet. AWR’s credit agreement contains affirmative and negative covenants and events of default customary for credit facilities of this type, including, among other things, affirmative covenants relating to compliance with law and material contracts, and negative covenants relating to additional indebtedness, liens, investments, restricted payments and asset sales by AWR and its subsidiaries, other than BVES. AWR is not permitted to have a consolidated total capitalization ratio (consolidated funded indebtedness to sum of shareholders’ equity and consolidated funded indebtedness), excluding AWR’s electric subsidiary, greater than 0.65 to 1.00 at the end of any quarter. Default under any indebtedness of any subsidiary of AWR, other than BVES, will result in a default under AWR’s credit agreement. GSWC’s credit agreement provides for a $200.0 million unsecured revolving credit facility to support its operations and capital expenditures. Under GSWC’s credit agreement, the borrowing capacity may be expanded up to an additional amount of $75.0 million, subject to the lenders’ approval. The aggregate amount that may be outstanding under letters of credit is $20.0 million. Loans may be obtained under this credit facility at the option of GSWC and bear interest at rates based on either a base rate plus an applicable margin or an adjusted term SOFR determined by the SOFR administrator plus an applicable margin. The applicable margin depends upon GSWC’s credit rating. GSWC's outstanding borrowings under the credit facility of $78.0 million as of June 30, 2023 have been classified as non-current liabilities on GSWC’s Balance Sheet. Similar to AWR's credit agreement, GSWC's credit agreement also contains affirmative and negative covenants and events of default customary for credit facilities of its type. GSWC is also not permitted to have a total capitalization ratio greater than 0.65 to 1.00 at the end of any quarter. Default under any indebtedness of any subsidiary of AWR will not result in a default under GSWC’s credit agreement.
