Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentationThe accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) for interim financial information, the instructions to SEC Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In preparing the unaudited condensed consolidated financial statements, management is required 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 balance sheet and the reported amounts of revenues and expenses for the period. Actual results could differ significantly from those estimates. The accompanying unaudited condensed consolidated financial statements and the following notes should be read in conjunction with the audited consolidated financial statements and the notes thereto in HEI’s and Hawaiian Electric’s Form 10-K for the year ended December 31, 2020.In the opinion of HEI’s and Hawaiian Electric’s management, the accompanying unaudited condensed consolidated financial statements contain all material adjustments required by GAAP to fairly state consolidated HEI’s and Hawaiian Electric’s financial positions as of June 30, 2021 and December 31, 2020 and the results of their operations for the three and six months ended June 30, 2021 and 2020 and cash flows for the six months ended June 30, 2021 and 2020. All such adjustments are of a normal recurring nature, unless otherwise disclosed below or in other referenced material. Results of operations for interim periods are not necessarily indicative of results for the full year. Recent accounting pronouncements. Income Taxes . In December 2019, Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which removes specific exceptions to the general principles in Topic 740, improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP under certain situations. ASU No. 2019-12 is effective for public business entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The Company adopted the ASU as of January 1, 2021 with no material impact on its consolidated financial statements and related disclosures. Leases . On July 19, 2021 FASB issued ASU No. 2021-05, “Leases (Topic 842): Lessors–Certain Leases with Variable Lease Payments.” The ASU allows lessors to treat sales-type leases with variable payments to be classified as operating leases if the sales-type lease treatment under Topic 842 would result in a selling loss at lease commencement (day-one loss). The Company plans to early adopt ASU No. 2021-05 as of September 30, 2021 retrospectively to leases that commenced on or after the adoption of ASU No. 2016-02. The impact of the adoption of ASU No. 2021-05 on the Company’s consolidated financial statements is not expected to be material.

Electric Utility Subsidiary [Abstract]
Electric utility segment	Electric utility segment Unconsolidated variable interest entities. Power purchase agreements . As of June 30, 2021, the Utilities had five PPAs for firm capacity (including the Puna Geothermal Venture (PGV) PPA that went offline in May 2018 due to lava flow on Hawaii Island, but returned to service with firm capacity of 13 MW in the first quarter of 2021 and ramped up to 23.9 MW in the second quarter of 2021) and other PPAs with independent power producers (IPPs) and Schedule Q providers (i.e., customers with cogeneration and/or power production facilities who buy power from or sell power to the Utilities), none of which are currently required to be consolidated as VIEs. Pursuant to the current accounting standards for VIEs, the Utilities are deemed to have a variable interest in Kalaeloa Partners, L.P. (Kalaeloa), AES Hawaii, Inc. (AES Hawaii) and Hamakua Energy by reason of the provisions of the PPA that the Utilities have with the three IPPs. However, management has concluded that the Utilities are not the primary beneficiary of Kalaeloa, AES Hawaii and Hamakua Energy because the Utilities do not have the power to direct the activities that most significantly impact the three IPPs’ economic performance nor the obligation to absorb their expected losses, if any, that could potentially be significant to the IPPs. Thus, the Utilities have not consolidated Kalaeloa, AES Hawaii and Hamakua Energy in its condensed consolidated financial statements. Hamakua Energy is an indirect subsidiary of Pacific Current and is consolidated in HEI’s condensed consolidated financial statements. Commitments and contingencies. Contingencies . The Utilities are subject in the normal course of business to pending and threatened legal proceedings. Management does not anticipate that the aggregate ultimate liability arising out of these pending or threatened legal proceedings will be material to its financial position. However, the Utilities cannot rule out the possibility that such outcomes could have a material effect on the results of operations or liquidity for a particular reporting period in the future. Power purchase agreements . Purchases from all IPPs were as follows: Three months ended June 30 Six months ended June 30 (in millions) 2021 2020 2021 2020 Kalaeloa $ 49 $ 34 $ 86 $ 72 AES Hawaii 36 32 66 63 HPOWER 14 17 31 34 Hamakua Energy 12 11 23 24 Puna Geothermal Venture 7 — 11 — Wind IPPs 28 25 57 53 Solar IPPs 16 17 28 28 Other IPPs 1 1 1 3 3 Total IPPs $ 163 $ 137 $ 305 $ 277 1 Includes hydro power and other PPAs Kalaeloa Partners, L.P. Under a 1988 PPA, as amended, Hawaiian Electric is committed to purchase 208 MW of firm capacity from Kalaeloa. Hawaiian Electric and Kalaeloa continue negotiations to address the PPA term that ended on May 23, 2016. The PPA automatically extends on a month-to-month basis as long as the parties are still negotiating in good faith. Hawaiian Electric and Kalaeloa have agreed that neither party will give notice of termination of negotiation prior to October 31, 2021, to allow for a negotiated resolution. As a result, since the PPA provides for a 60-day notice of termination of the PPA, the PPA will remain in full force and effect through October 31, 2021, and from month to month thereafter, subject to termination on not less than 60 days notice. AES Hawaii, Inc. Under a PPA entered into in March 1988, as amended (through Amendment No. 2) for a period of 30 years ending September 2022, Hawaiian Electric agreed to purchase 180 MW of firm capacity from AES Hawaii. Hawaiian Electric and AES Hawaii have been in dispute over an additional 9 MW of capacity. In February 2018, Hawaiian Electric reached agreement with AES Hawaii on an amendment to the PPA. However, in June 2018, the PUC issued an order suspending review of the amendment pending a Department of Health of the State of Hawaii ( DOH) decision on AES Hawaii’s request for approval of its Emission Reduction Plan and partnership with Hawaiian Electric. If approved by the PUC, the amendment will resolve AES Hawaii’s claims related to the additional capacity. Hawaiian Electric does not intend to extend the term of the PPA which will expire on September 1, 2022. Hu Honua Bioenergy, LLC (Hu Honua). In May 2012, Hawaii Electric Light signed a PPA, which the PUC approved in December 2013, with Hu Honua for 21.5 MW of renewable, dispatchable firm capacity fueled by locally grown biomass from a facility on the island of Hawaii. Under the terms of the PPA, the Hu Honua plant was scheduled to be in service in 2016. However, Hu Honua encountered construction and litigation delays, which resulted in an amended and restated PPA between Hawaii Electric Light and Hu Honua dated May 9, 2017. In July 2017, the PUC approved the amended and restated PPA, which becomes effective once the PUC’s order is final and non-appealable. In August 2017, the PUC’s approval was appealed by a third party. On May 10, 2019, the Hawaii Supreme Court issued a decision remanding the matter to the PUC for further proceedings consistent with the court’s decision which must include express consideration of greenhouse gas (GHG) emissions that would result from approving the PPA, whether the cost of energy under the PPA is reasonable in light of the potential for GHG emissions, and whether the terms of the PPA are prudent and in the public interest, in light of its potential hidden and long-term consequences. As a result, the PUC reopened the docket for further proceedings, including re-examining all of the issues in the proceedings. On July 9, 2020, the PUC issued an order denying Hawaii Electric Light’s request to waive the amended and restated PPA from the PUC’s competitive bidding requirements and therefore, dismissed the request for approval of the amended and restated PPA without prejudice to possible participation in any future competitive bidding process. On September 9, 2020, the PUC denied Hu Honua’s motion for reconsideration of the PUC’s order. Hu Honua filed its notice of appeal to the Hawaii Supreme Court of the PUC’s order denying Hu Honua’s motion for reconsideration. On May 24, 2021, the Hawaii Supreme Court vacated the PUC’s decision and remanded the matter back to the PUC for further proceedings. On June 30, 2021, the PUC issued an order reopening the docket consistent with the Hawaii Supreme Court’s order. Molokai New Energy Partners (MNEP). In July 2018, the PUC approved Maui Electric’s PPA with MNEP to purchase solar energy from a photovoltaic (PV) plus battery storage project. The 4.88 MW PV and 3 MW Battery Energy Storage System project was to deliver no more than 2.64 MW at any time to the Molokai system. On March 25, 2020, MNEP filed a complaint in the United Stated District Court for the District of Hawaii against Maui Electric claiming breach of contract. On June 3, 2020, Maui Electric provided Notice of Default and Termination of the PPA to MNEP terminating the PPA with an effective date of July 10, 2020. Thereafter, MNEP filed an amended Complaint to include claims relating to the termination and Hawaiian Electric filed its Answer to the Amended Complaint on September 11, 2020, disputing the facts presented by MNEP and all claims within the original and amended complaint. Utility projects . Many public utility projects require PUC approval and various permits from other governmental agencies. Difficulties in obtaining, or the inability to obtain, the necessary approvals or permits or community support can result in significantly increased project costs or even cancellation of projects. In the event a project does not proceed, or if it becomes probable the PUC will disallow cost recovery for all or part of a project, or if PUC-imposed caps on project costs are expected to be exceeded, project costs may need to be written off in amounts that could result in significant reductions in Hawaiian Electric’s consolidated net income. Enterprise Resource Planning/Enterprise Asset Management (ERP/EAM) implementation project. The ERP/EAM Implementation Project went live in October 2018. Hawaii Electric Light and Hawaiian Electric began to incorporate their portion of the deferred project costs in rate base and started the amortization over a 12-year period in January 2020 and November 2020, respectively. The PUC required the benefit savings of the project to be passed on to customers. In February 2019, the PUC approved a methodology for passing the future cost saving benefits of the new ERP/EAM system to customers developed by the Utilities in collaboration with the Consumer Advocate. The Utilities filed a benefits clarification document on June 10, 2019, reflecting $150 million in future net O&M expense reductions and cost avoidance, and $96 million in capital cost reductions and tax savings over the 12-year service life. To the extent the reduction in O&M expense relates to amounts reflected in electric rates, the Utilities would reduce future rates for such amounts. In October 2019, the PUC approved the Utilities and the Consumer Advocate’s Stipulated Performance Metrics and Tracking Mechanism. As of June 30, 2021, the Utilities’ regulatory liability was $11.1 million ($6.1 million for Hawaiian Electric, $2.0 million for Hawaii Electric Light and $3.0 million for Maui Electric) for the O&M expense savings that are being amortized or to be included in future rates. As part of the settlement agreement approved in the Hawaiian Electric 2020 test year rate case, the regulatory liability for Hawaiian Electric will be amortized over five years, beginning in November 2020, and the O&M benefits for Hawaiian Electric was considered flowed through to customers. As part of the PBR proceeding, the regulatory liability as of December 31, 2020 of approximately $1.6 million and $2.3 million, respectively, for Hawaii Electric Light and Maui Electric was flowed to customers as part of the customer dividend in the annual revenue adjustment in 2021. At the PUC’s direction, the Utilities have been filing Semi-Annual Enterprise System Benefits (SAESB) reports on the achieved benefits savings. The most recent SAESB report was filed on February 26, 2021 for the period July 1 through December 31, 2020. Environmental regulation . The Utilities are subject to environmental laws and regulations that regulate the operation of existing facilities, the construction and operation of new facilities and the proper cleanup and disposal of hazardous waste and toxic substances. Hawaiian Electric, Hawaii Electric Light and Maui Electric, like other utilities, periodically encounter petroleum or other chemical releases associated with current or previous operations. The Utilities report and take action on these releases when and as required by applicable law and regulations. The Utilities believe the costs of responding to such releases identified to date will not have a material effect, individually or in the aggregate, on Hawaiian Electric’s consolidated results of operations, financial condition or liquidity. Former Molokai Electric Company generation site . In 1989, Maui Electric acquired Molokai Electric Company. Molokai Electric Company had sold its former generation site (Site) in 1983, but continued to operate at the Site under a lease until 1985. The federal Environmental Protection Agency (EPA) has since identified environmental impacts in the subsurface soil at the Site. In cooperation with the DOH and EPA, Maui Electric further investigated the Site and the Adjacent Parcel to determine the extent of impacts of polychlorinated biphenyls (PCBs), residual fuel oils and other subsurface contaminants. Maui Electric has a reserve balance of $2.7 million as of June 30, 2021, representing the probable and reasonably estimable undiscounted cost for remediation of the Site and the Adjacent Parcel; however, final costs of remediation will depend on the cleanup approach implemented. Pearl Harbor sediment study . In July 2014, the U.S. Navy notified Hawaiian Electric of the Navy’s determination that Hawaiian Electric is a Potentially Responsible Party responsible for the costs of investigation and cleanup of PCBs contamination in sediment in the area offshore of the Waiau Power Plant as part of the Pearl Harbor Superfund Site. Hawaiian Electric was also required by the EPA to assess potential sources and extent of PCB contamination onshore at Waiau Power Plant. As of June 30, 2021, the reserve account balance recorded by Hawaiian Electric to address the PCB contamination was $10.5 million. The reserve balance represents the probable and reasonably estimable undiscounted cost for the onshore and offshore investigation and remediation. The final remediation costs will depend on the actual onshore and offshore cleanup costs. Regulatory proceedings Decoupling . Decoupling is a regulatory model that is intended to provide the Utilities with financial stability and facilitate meeting the State of Hawaii’s goals to transition to a clean energy economy and achieve an aggressive renewable portfolio standard. Prior to the implementation of the performance-based regulation framework (PBR Framework), the decoupling mechanism had the following major components: (1) monthly revenue balancing account (RBA) revenues or refunds for the difference between PUC-approved target revenues and recorded adjusted revenues, which delinks revenues from kWh sales, (2) rate adjustment mechanism (RAM) revenues for escalation in certain O&M expenses and rate base changes, (3) major project interim recovery (MPIR) adjustment mechanism, (4) performance incentive mechanisms (PIMs), and (5) an earnings sharing mechanism (ESM), which would provide for a reduction of revenues between rate cases in the event the utility exceeds the return on average common equity (ROACE) allowed in its most recent rate case. Performance-based regulation framework. On December 23, 2020, the PUC issued a D&O (PBR D&O) approving the new PBR Framework. Under the PBR Framework, the Utilities’ decoupling will continue to be used with modifications, as described below. The existing cost recovery mechanisms will continue as currently implemented (e.g., the Energy Cost Recovery Clause (ECRC), Purchased Power Adjustment Clause (PPAC), Demand Side Management surcharge (DSM), Renewable Energy Infrastructure Program (REIP), Demand Response Adjustment Clause (DRAC), Pension and Other Post-Employment Benefits (OPEB) tracking mechanisms). In addition to annual revenues provided by the annual revenue adjustment (ARA), the Utilities may seek relief for extraordinary projects or programs through the Exceptional Project Recovery Mechanism (EPRM) (formerly known as the MPIR adjustment mechanism) and earn financial rewards for exemplary performance as provided through a portfolio of PIMs and Shared Savings Mechanisms (SSMs). The PBR Framework will incorporate a variety of other performance mechanisms, including Scorecards, Reported Metrics, and an expedited Pilot Process. The PBR Framework also contains a number of safeguards, including a symmetric ESM which protects the Utilities and customers from excessive earnings or losses, as measured by the Utilities’ Return on Equity (ROE) and a Re-Opener mechanism, under which the PUC will open an examination, at its discretion, to determine if adjustments or modifications to specific PBR mechanisms are appropriate. Rate adjustment mechanism . The RAM is based on the lesser of: a) an inflationary adjustment for certain O&M expenses and return on investment for certain rate base changes, or b) cumulative annual compounded increase in Gross Domestic Product Price Index applied to annualized target revenues (the RAM Cap). All Utilities were limited to the RAM Cap in 2020. Under the PBR Framework, the ARA mechanism replaced the RAM, and became effective on June 1, 2021. The transition to the ARA includes the continuation of the 2020 RAM revenue adjustment. Annual revenue adjustment mechanism . The PBR Framework established a five-year multi-year rate period during which there will be no general rate cases. Target revenues will be adjusted according to an index-driven ARA based on (i) an inflation factor, (ii) a predetermined X-factor to encompass productivity, which is set at zero, (iii) a Z-factor to account for exceptional circumstances not in the Utilities’ control and (iv) a customer dividend consisting of a negative adjustment of 0.22% compounded annually and a flow through of the “pre-PBR” savings commitment from the management audit recommendations developed in a prior docket. As a result of an Order issued by the PUC pursuant to a motion for partial reconsideration the customer dividend for “pre-PBR” savings commitment portion to be delivered to customers will be at a rate of $6.6 million per year from 2021 to 2025, and the Enterprise Resource Planning system benefits savings of $3.9 million, to be delivered to customers in 2021. The implementation of the ARA occurred on June 1, 2021. Earnings sharing mechanism . A symmetrical ESM for actual return on equity outside of a 300 basis points dead band above and below a target ROE of 9.5%, which is the current authorized ROE for the Utilities. There is a 50/50 sharing between customers and Utilities for the actual earnings falling within 150 basis points outside of the dead band in either direction, and a 90/10 sharing for any further difference. A reopening or review of the PBR terms will be triggered if the Utilities credit rating outlook indicates a potential credit downgrade below investment grade status, or if its earned ROE enters the outer most tier of the ESM. Major project interim recovery . On April 27, 2017, the PUC issued an order that provided guidelines for interim recovery of revenues to support major projects placed in service between general rate cases. Projects eligible for recovery through the MPIR adjustment mechanism are major projects (i.e., projects with capital expenditures net of customer contributions in excess of $2.5 million), including, but not restricted to, renewable energy, energy efficiency, utility scale generation, grid modernization and smaller qualifying projects grouped into programs for review. The MPIR adjustment mechanism provides the opportunity to recover revenues for approved costs of eligible projects placed in service between general rate cases wherein cost recovery is limited by a revenue cap and is not provided by other effective recovery mechanisms. The request for PUC approval must include a business case, and all costs that are allowed to be recovered through the MPIR adjustment mechanism must be offset by any related benefits. The guidelines provide for accrual of revenues approved for recovery upon in-service date to be collected from customers through the annual RBA tariff. Capital projects that are not recovered through the MPIR would be included in the RAM and be subject to the RAM Cap, until the next rate case when the Utilities would request recovery in base rates. On May 26, 2021, the PUC approved 2021 MPIR amounts totaling $21.8 million, including revenue taxes, for the Schofield Generating Station ($17.6 million), West Loch PV Project ($3.3 million), and Grid Modernization Strategy Phase 1 project ($0.9 million for all three utilities) for the accrual of revenues effective January 1, 2021, that included the 2021 return on project amount (based on approved amounts) in rate base, depreciation and incremental O&M expenses. Under the PBR framework, the Utilities began recovery of the annualized 2021 MPIR amounts effective June 1, 2021 through the RBA rate adjustment. Exceptional project recovery mechanism . Under the PBR framework, the existing MPIR adjustment mechanism was renamed EPRM to include deferred and O&M expense projects and to permit the Utilities to include the full amount of approved costs in the EPRM for recovery in the first year the project goes into service, pro-rated for the portion of the year the project is in service. Any pending application for MPIR relief submitted by the Utilities prior to the PBR D&O, will be grandfathered under the MPIR Guidelines. The Utilities may alternatively request that pending MPIR applications be reviewed under EPRM Guidelines. EPRM recovery will be in accordance with the EPRM Guidelines limited to the lesser of actual incurred project costs or PUC-approved amounts, net of savings. Currently, the Utilities are seeking EPRM recovery of seven projects with total project costs of $245 million, subject to PUC approval. Pilot process . The PBR D&O approved a Pilot Process to foster innovation by establishing an expedited implementation process for pilots that test new technologies, programs, business models, and other arrangements. This is intended to support initiatives by the Utilities to test new programs and ideas quickly and elevate any successful pilots for consideration of full-scale implementation. The proposed pilots would be subject to PUC approval with a total annual cap of $10 million. The Pilot Process will feature the two primary activities: an initial “Workplan Development” phase, during which the Utilities identify and scope areas of interests, so as to inform the subsequent “Implementation” phase, during which the Utilities submit specific pilot proposals for expedited review by the PUC and implement the pilot upon approval. The PUC will issue an order, approving, denying, or modifying a proposed Pilot within 45 days of receiving notice of a specific pilot project. On July 9, 2021, the PUC issued an order approving the Utilities’ proposed Pilot Process submitted in April 2021, including a cost recovery process that generally allows the Utilities to defer and recover total annual expenditures of approved pilot projects in full over twelve months beginning June 1 of the year following implementation through the RBA rate adjustment, although the Utilities may determine on a case-by-case basis that a particular project’s deferred costs should be amortized over a period greater than twelve months. Performance incentive mechanisms . The PUC has established the following PIMs: (1) Service Quality performance incentives, (2) Phase 1 Request for proposal (RFP) PIM for procurement of low-cost renewable energy, (3) Phase 2 RFP PIMs for generation and generation plus storage project, and Grid Services and standalone storage. • Service Quality performance incentives (ongoing). Service Quality performance incentives are measured on a calendar-year basis. The PIM tariff requires the performance targets, deadbands and the amount of maximum financial incentives used to determine the PIM financial incentive levels for each of the PIMs to be re-determined upon issuance of an interim or final order in a general rate case for each utility. • Service Reliability Performance measured by System Average Interruption Duration and Frequency Indexes (penalties only). Target performance is based on each utility’s historical 10-year average performance with a deadband of one standard deviation. The maximum penalty for each performance index is 20 basis points applied to the common equity share of each respective utility’s approved rate base (or maximum penalties of approximately $6.8 million - for both indices in total for the three utilities). • Call Center Performance measured by the percentage of calls answered within 30 seconds. Target performance is based on the annual average performance for each utility for the most recent 8 quarters with a deadband of 3% above and below the target. The maximum penalty or reward is 8 basis points applied to the common equity share of each respective utility’s approved rate base (or maximum penalties or rewards of approximately $1.4 million - in total for the three utilities). In December 2020, the Utilities accrued $0.9 million in estimated rewards for call center performance, net of service reliability penalties, for 2020. The net service quality performance rewards related to 2020 was reflected in the 2021 annual decoupling filing which was approved by the PUC on May 26, 2021, resulting in an increase to customer rates effective June 1, 2021. • Phase 1 RFP PIM. Procurement of low-cost variable renewable resources through the RFP process in 2018 is measured by comparison of the procurement price to target prices. Half of the incentive was earned upon PUC approval of the PPAs. Based on the seven PPAs approved in 2019, the Utilities recognized $1.7 million in 2019 with the remaining award to be recognized in the year following the in-service date of the projects, which is estimated to occur from 2023 to 2024. • Phase 2 RFP PIMs. The PUC order issued on October 9, 2019 establishes pricing thresholds, timelines to complete contracting, and other performance criteria for the performance incentive eligibility. The PIMs provide incentives only without penalties. The order requires contracts under the Grid Service RFP be filed for approval by May 2020 (subsequently extended to July 9, 2020), and by September 2020 under the Renewable RFPs, with a declining PIM for projects that are not filed by these deadlines. On July 9, 2020, the Utilities filed two Grid Service Purchase Agreements for the Grid Service RFP that potentially qualify for a demand response PIM, however, details of the incentive metrics will be determined by the PUC. On September 15, 2020, the Utilities filed eight power purchase agreements for the Phase 2 RFP. Of those eight, only one project qualified for a potential PIM incentive. On February 16, 2021, the Utilities filed one additional power purchase agreement that qualifies for the declining PIM. On December 31, 2020, the PUC approved the two Grid Services Purchase Agreements without further clarification regarding the demand response PIM. The Utility filed a letter in January 2021 with the PUC seeking guidance on the next steps to define the demand response incentive metric details. • The PUC established the following two new PIMs in its PBR D&O, which were approved in an order issued on March 23, 2021 and became effective on June 1, 2021. • Renewable portfolio standard (RPS)-A PIM that provides a financial reward for accelerating the achievement of RPS goals. The Utilities may earn a reward for the amount of system generation above the interpolated statutory RPS goal at $20/MWh in 2021 and 2022, $15/MWh in 2023, and $10/MWh for the remainder of the multi-year rate period (MRP). Penalties are already prescribed in the RPS as $20/MWh for failing to meet RPS targets in 2030, 2040 and 2045. The evaluation period commenced on January 1, 2021. • Grid Services Procurement PIM that provides financial rewards for grid services acquired in 2021 and 2022. The Utilities can earn a total maximum reward of $1.5 million over 2021 and 2022. The evaluation period commenced on January 1, 2021. • The PUC also established the following three new PIMs in its PBR D&O, which were approved by the PUC on May 17, 2021 and became effective on June 1, 2021. • Interconnection Approval PIM that provides financial rewards and penalties for interconnection times for distributed energy resources systems <100 kW in size. The Utilities can earn a total annual maximum reward of $3.0 million or a total annual maximum penalty of $0.9 million. The evaluation period commenced on January 1, 2021. • Low-to-Moderate Income (LMI) Energy Efficiency PIM that provides financial reward for collaboration between the Utilities and the third-party Public Benefits Fee Administrator to deliver energy savings for low- and moderate-income customers. The Utilities can earn a total annual maximum reward of $2.0 million. The PIM will initially have a duration of three years and be subject to an annual review. The evaluation period is based on Hawaii Energy’s program year with the initial evaluation year being the period of July 1, 2021 through June 30, 2022. • Advanced Metering Infrastructure Utilization PIM that provides financial rewards for leveraging grid modernization investments and engaging customers beyond what is already planned in the Phase 1 Grid Modernization program. The Utilities can earn a total annual maximum reward of $2.0 million. The PIM will initially have a duration of three years after which it will be re-evaluated. The evaluation period commenced on January 1, 2021. Annual decoupling filings . The filing reflected ARA revenues for 2021 to be collected from June 1 through December 31, 2021, as follows: (in millions) Hawaiian Electric Hawaii Electric Light Maui Electric Total 2021 ARA revenues $ 6.9 $ 1.7 $ 1.7 $ 10.3 Management Audit savings commitment (4.6) (1.0) (1.0) (6.6) Net incremental revenues $ 2.3 $ 0.7 $ 0.7 $ 3.7 The net incremental amounts to be collected (refunded) from June 1, 2021 through December 31, 2021 under the RBA rate tariffs are as follows: (in millions) Hawaiian Electric Hawaii Electric Light Maui Electric Total Incremental RAM revenues and ARA revenues $ (14.7) $ (2.2) $ (6.1) $ (23.0) Annual change in accrued RBA balance as of December 31, 2020 (and associated revenue taxes) 10.4 5.7 8.9 25.0 Incremental Performance Incentive Mechanisms (net) — 0.2 0.5 0.7 Incremental MPIR/EPRM Revenue Adjustment 12.6 0.1 0.1 12.8 Incremental Affiliate Transaction Refund/PUC Ordered Adjustment — N/A 2.0 2.0 Net incremental amount to be collected under the RBA rate tariffs $ 8.3 $ 3.8 $ 5.3 $ 17.4 Note: Columns may not foot due to rounding. Most recent rate proceedings. Hawaiian Electric 2020 test year rate case . On October 22, 2020, the PUC issued a final D&O approving the stipulated settlement agreement filed in the proceeding. As a result, there will be no increase in base electric rates established in the 2017 test year rate case. In the final D&O, the PUC approved the capital structure that consists of a 58% total equity ratio, and a ROACE of 9.5% for the 2020 test year. The resulting return on rate base (RORB) is 7.37%. The D&O approved the agreement to implement the overall lower depreciation rates approved in the last depreciation study proceeding, effective January 1, 2020. See “Annual revenue adjustment mechanism” under “Performance-based regulation framework” above, regarding the PUC’s decision on the treatment of Hawaiian Electric’s Management Audit savings commitment. Hawaiian Electric’s proposed RBA provision tariff and ECRC tariff submitted on November 6, 2020 were approved by the PUC on December 11, 2020 and took effect on January 1, 2021. Hawaii Electric Light 2019 test year rate case . On July 28, 2020, the PUC issued a final D&O, approving the Stipulated Partial Settlement Letter in part and ordering final rates for the 2019 test year to remain at current effective rates such that there is a zero increase in rates. The PUC determined that an appropriate ROACE for the 2019 test year is 9.5%, approved a capital structure of 58% total equity and approved as fair a 7.52% RORB. In addition, the order, among others, (1) approved a 10-year amortization period for the state investment tax credit; and (2) approved a modification to Hawaii Electric Light’s ECRC to incorporate a 98%/2% risk-sharing split between customers and Hawaii Electric Light with an annual maximum exposure cap of +/- $600,000. The proposed final tariffs and PIM tariffs took effect on November 1, 2020, and the ECRC tariff took effect on January 1, 2021. Regulatory assets for COVID-19 related costs. On May 4, 2020, the PUC issued an order, authorizing all utilities, including the Utilities, to establish regulatory assets to record costs resulting from the suspension of disconnections of service during the pendency of the Governor’s Emergency Proclamation and until otherwise ordered by the PUC. In future proceedings, the PUC will consider the reasonableness of the costs, the appropriate period of recovery, any amount of carrying costs thereon, and any savings directly attributable to suspension of disconnects, and other related matters. As part of the order, the PUC prohibits the Utilities from charging late payment fees on past due payments. On June 30, 2020, the PUC issued an order approving the Utilities’ request made in April 2020 for deferral treatment of COVID-19 related costs through December 31, 2020. On March 8, 2021, the PUC approved the Utilities’ request to extend the deferral period to June 30, 2021. The Utilities’ request to extend the deferral period to December 31, 2021 is pending PUC approval. The Utilities are required to file quarterly reports to update the Utilities’ financial condition, report measures in place to assist their customers during the COVID-19 emergency situation, identify the planned deferred costs and details for the deferred costs, and identify funds received or benefits receiv

Total gross unrealized losses were primarily attributable to change in market conditions. On a quarterly basis the investment securities are evaluated for changes in financial condition of the issuer. Based upon ASB’s evaluation, all securities held within the investment portfolio continue to be investment grade by one or more agencies. The contractual cash flows of the U.S. Treasury, federal agency obligations and agency mortgage-backed securities are backed by the full faith and credit guaranty of the United States government or an agency of the government. ASB does not intend to sell the securities before the recovery of its amortized cost basis and there have been no adverse changes in the timing of the contractual cash flows for the securities. ASB’s investment securities portfolio did not require an allowance for credit losses at June 30, 2021 and December 31, 2020. U.S. Treasury, federal agency obligations, corporate bonds, and mortgage revenue bonds have contractual terms to maturity. Mortgage-backed securities have contractual terms to maturity, but require periodic payments to reduce principal. In addition, expected maturities will differ from contractual maturities because borrowers have the right to prepay the underlying mortgages.

ASB performs an internal loan review and grading on an ongoing basis. The review provides management with periodic information as to the quality of the loan portfolio and effectiveness of its lending policies and procedures. The objectives of the loan review and grading procedures are to identify, in a timely manner, existing or emerging credit trends so that appropriate steps can be initiated to manage risk and avoid or minimize future losses. Loans subject to grading include commercial, commercial real estate and commercial construction loans. Each commercial and commercial real estate loan is assigned an Asset Quality Rating (AQR) reflecting the likelihood of repayment or orderly liquidation of that loan transaction pursuant to regulatory credit classifications: Pass, Special Mention, Substandard, Doubtful, and Loss. The AQR is a function of the probability of default model rating, the loss given default, and possible non-model factors which impact the ultimate collectability of the loan such as character of the business owner/guarantor, interim period performance, litigation, tax liens and major changes in business and economic conditions. Pass exposures generally are well protected by the current net worth and paying capacity of the obligor or by the value of the asset or underlying collateral. Special Mention loans have potential weaknesses that, if left uncorrected, could jeopardize the liquidation of the debt. Substandard loans have well-defined weaknesses that jeopardize the liquidation of the debt and are characterized by the distinct possibility that ASB may sustain some loss. An asset classified Doubtful has the weaknesses of those classified Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. An asset classified Loss is considered uncollectible and has such little value that its continuance as a bankable asset is not warranted.

Troubled debt restructurings. A loan modification is deemed to be a TDR when the borrower is determined to be experiencing financial difficulties and ASB grants a concession it would not otherwise consider. The allowance for credit losses on TDR loans that do not share risk characteristics are individually evaluated based on the present value of expected future cash flows discounted at the loan’s effective original contractual rate or based on the fair value of collateral less cost to sell. The financial impact of the estimated loss is an increase to the allowance associated with the modified loan. When available information confirms that specific loans or portions thereof are uncollectible (confirmed losses), these amounts are charged off against the allowance for credit losses. Loan modifications that occurred during the three and six months ended June 30, 2021 and 2020 were as follows: Loans modified as a TDR Three months ended June 30, 2021 Six months ended June 30, 2021 (dollars in thousands) Number Outstanding recorded investment (as of period end) 1 Related allowance (as of period end) Number Outstanding recorded investment (as of period end) 1 Related allowance (as of period end) Troubled debt restructurings Real estate: Residential 1-4 family 3 $ 1,835 $ 77 15 $ 10,024 $ 271 Commercial real estate — — — — — — Home equity line of credit — — — 1 163 18 Residential land 1 288 12 2 558 23 Commercial construction — — — — — — Residential construction — — — — — — Commercial 4 237 11 6 296 26 Consumer — — — — — — 8 $ 2,360 $ 100 24 $ 11,041 $ 338 Three months ended June 30, 2020 Six months ended June 30, 2020 (dollars in thousands) Number Outstanding recorded investment (as of period end) 1 Related allowance (as of period end) Number Outstanding recorded investment (as of period end) 1 Related allowance (as of period end) Troubled debt restructurings Real estate: Residential 1-4 family — $ — $ — 1 $ 147 $ 7 Commercial real estate — — — 2 16,430 4,301 Home equity line of credit 2 19 3 2 19 3 Residential land 2 330 — 2 330 — Commercial construction — — — — — — Residential construction — — — — — — Commercial — — — 4 751 275 Consumer — — — — — — 4 $ 349 $ 3 11 $ 17,677 $ 4,586 1 The period end balances reflect all paydowns and charge-offs since the modification period. TDRs fully paid off, charged-off, or foreclosed upon by period end are not included. There were no loans modified in TDRs that experienced a payment default of 90 days or more during the second quarter and first six months of 2021 and 2020. If a loan modified in a TDR subsequently defaults, ASB evaluates the loan for further impairment. Based on its evaluation, adjustments may be made in the allocation of the allowance or partial charge-offs may be taken to further write-down the carrying value of the loan. Commitments to lend additional funds to borrowers whose loan terms have been modified in a TDR totaled nil at June 30, 2021 and December 31, 2020. The Coronavirus Aid, Relief, and Economic Security Act (CARES Act) provides that a financial institution may elect to suspend the requirements under GAAP for certain loan modifications that would otherwise be categorized as a TDR and any related impairment for accounting purposes. In response to the COVID-19 pandemic, the Board of Governors of the FRB, the FDIC, the National Credit Union Administration, the OCC, and the Consumer Financial Protection Bureau, in consultation with the state financial regulators (collectively, the “agencies”) issued a joint interagency statement (issued March 22, 2020; revised statement issued April 7, 2020). Some of the provisions applicable to the Company include, but are not limited to accounting for loan modifications, past due reporting and nonaccrual status and charge-offs. Loan modifications that do not meet the conditions of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. The agencies confirmed with the FASB staff that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or insignificant delays in payment. Financial institutions are not expected to designate loans with deferrals granted due to COVID-19 as past due because of the deferral. A loan’s payment date is governed by the due date stipulated in the legal agreement. If a financial institution agrees to a payment deferral, these loans would not be considered past due during the period of the deferral. Lastly, during short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified. Collateral-dependent loans. A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the operation or sale of the collateral. Loans considered collateral-dependent were as follows: Amortized cost (in thousands) June 30, 2021 December 31, 2020 Collateral type Real estate: Residential 1-4 family $ 4,454 $ 2,541 Residential real estate property Commercial real estate 1,437 2,875 Commercial real estate property Home equity line of credit 1,415 1,567 Residential real estate property Residential land 300 300 Residential real estate property Total real estate 7,606 7,283 Commercial 840 934 Business assets Total $ 8,446 $ 8,217 ASB had $3.8 million of mortgage loans collateralized by residential real estate property that were in the process of foreclosure at June 30, 2021 and December 31, 2020. Mortgage servicing rights (MSRs) . In its mortgage banking business, ASB sells residential mortgage loans to government-sponsored entities and other parties, who may issue securities backed by pools of such loans. ASB retains no beneficial interests in these loans other than the servicing rights of certain loans sold. ASB received proceeds from the sale of residential mortgages of $95.6 million and $186.8 million for the three months ended June 30, 2021 and 2020, respectively, $266.5 million and $259.3 million for the six months ended June 30, 2021 and 2020, respectively, and recognized gains on such sales of $1.9 million and $6.3 million for the three months ended June 30, 2021 and 2020, respectively, $6.2 million and $8.3 million for the six months ended June 30, 2021 and 2020, respectively. There were no repurchased mortgage loans for the three and six months ended June 30, 2021 and 2020. The repurchase reserve, which represents ASB’s loss estimate related to mortgage loan repurchases, was $0.1 million as of June 30, 2021 and 2020. Mortgage servicing fees, a component of other income, net, were $1.0 million and $0.8 million for the three months ended June 30, 2021 and 2020, respectively, and were $1.9 million and $1.6 million for the six months ended June 30, 2021 and 2020, respectively. Changes in the carrying value of MSRs were as follows: (in thousands) Gross carrying amount 1 Accumulated amortization Valuation allowance Net June 30, 2021 $ 21,865 $ (11,111) $ — $ 10,754 December 31, 2020 22,950 (12,670) (260) 10,020 1 Reflects impact of loans paid in full Changes related to MSRs were as follows: Three months ended June 30, Six months ended June 30 (in thousands) 2021 2020 2021 2020 Mortgage servicing rights Beginning balance $ 10,689 $ 9,120 $ 10,280 $ 9,101 Amount capitalized 1,023 1,726 2,570 2,362 Amortization (958) (935) (2,096) (1,552) Other-than-temporary impairment — — — — Carrying amount before valuation allowance 10,754 9,911 10,754 9,911 Valuation allowance for mortgage servicing rights Beginning balance 4 — 260 — Provision (4) 264 (260) 264 Other-than-temporary impairment — — — — Ending balance — 264 — 264 Net carrying value of mortgage servicing rights $ 10,754 $ 9,647 $ 10,754 $ 9,647 ASB capitalizes MSRs acquired upon the sale of mortgage loans with servicing rights retained. On a monthly basis, ASB compares the net carrying value of the MSRs to its fair value to determine if there are any changes to the valuation allowance and/or other-than-temporary impairment for the MSRs. ASB uses a present value cash flow model to estimate the fair value of MSRs. Impairment is recognized through a valuation allowance for each stratum when the carrying amount exceeds fair value, with any associated provision recorded as a component of loan servicing fees included in “Revenues - bank” in the condensed consolidated statements of income. A direct write-down is recorded when the recoverability of the valuation allowance is deem

Credit agreements	Credit agreements On May 14, 2021, HEI and Hawaiian Electric (each a Company, and collectively the Companies) each entered into a separate agreement with a syndicate of nine financial institutions (the HEI Facility and Hawaiian Electric Facility, respectively, and together, the Amended Facilities) to amend and restate their respective previously existing revolving unsecured credit agreements. The HEI Facility was increased to $175 million from $150 million and its term was extended to May 14, 2026. The $200 million Hawaiian Electric Facility has an initial term that expires on May 13, 2022, but its term will extend to May 14, 2026 upon approval by the PUC during the initial term, which approval has been requested. In addition to extending the term, Hawaiian Electric also requested PUC approval to exercise its options of two one-year extensions of the commitment termination date and to increase its aggregate revolving commitment amount from $200 million to $275 million, should there be a need. None of the facilities are collateralized. As of June 30, 2021 and December 31, 2020, no amounts were outstanding under the Credit Facilities. The Credit Facilities will be maintained to support each company’s respective short-term commercial paper program, but may be drawn on to meet each company’s respective working capital needs and general corporate purposes. Under the Amended Facilities, draws would generally bear interest, based on each Company’s respective current long-term credit ratings, at the “Adjusted LIBO Rate,” as defined in the Amended Facilities, plus 137.5 and 125.0 basis points for HEI and Hawaiian Electric, respectively, and incur annual fees on undrawn commitments, excluding swingline borrowings, of 20.0 and 17.5 basis points for HEI and Hawaiian Electric, respectively. The Amended Facilities also include provisions to accommodate a transition from the London Interbank Offered Rate (LIBOR) to an alternative reference rate, based on the secured overnight financing rate administered by the Federal Reserve Bank of New York, upon the phase out of LIBOR as a reference rate. Additionally, the Amended Facilities contain provisions for pricing adjustments in the event of a long-term ratings change based on the respective Facility’s ratings-based pricing grid, which includes the ratings by Fitch Ratings, Inc. (Fitch), Moody’s Investor Service’s (Moody’s) and Standard & Poor’s (S&P). The Amended Facilities do not contain clauses that would affect access to the Amended Facilities by reason of a ratings downgrade, nor do they have broad “material adverse change” clauses. In addition, the Amended Facilities contain provisions for potential annual pricing adjustments to the Eurodollar or Alternate Base Rate margin on draws and fees on undrawn commitments of up to +/-5 basis points and +/-1 basis point, respectively, based on performance against certain sustainability-linked metrics. The sustainability-linked metrics include achievement of renewable portfolio standards in excess of statutory requirements and increasing cumulative penetration of installed MWs of photovoltaic systems on residential rooftops. The Amended Facilities also include updated terms and conditions customary for facilities of this type and contain customary conditions that must be met in order to draw on them, including compliance with covenants (such as covenants preventing HEI’s and Hawaiian Electric’s respective subsidiaries from entering into agreements that restrict the ability of such subsidiaries to pay dividends to, or to repay borrowings from, HEI or Hawaiian Electric, as applicable; and a covenant in Hawaiian Electric’s facility restricting Hawaiian Electric’s ability, as well as the ability of any of its subsidiaries, to guarantee additional indebtedness of the subsidiaries if such additional debt would cause the subsidiary’s “Consolidated Subsidiary Funded Debt to Capitalization Ratio” (as defined in the Hawaiian Electric Facility) to exceed 65%). Under the HEI Facility, it is an event of default if HEI fails to maintain an unconsolidated “Capitalization Ratio” (funded debt) (as defined in the HEI Facility) of 50% or less or if HEI no longer owns Hawaiian Electric or ASB. Under the Hawaiian Electric Facility, it is an event of default if Hawaiian Electric fails to maintain a “Consolidated Capitalization Ratio” (equity) (as defined in the Hawaiian Electric Facility) of at least 35%, or if Hawaiian Electric is no longer owned by HEI. Hawaiian Electric had a $75 million 364-day revolving credit agreement, under which no amounts had been drawn. On April 19, 2021, the revolving credit agreement terminated and was not renewed.

Retirement Benefits [Abstract]
Retirement benefits	Retirement benefits Defined benefit pension and other postretirement benefit plans information. For the first six months of 2021, the Company contributed $23 million ($23 million by the Utilities) to its pension and other postretirement benefit plans, compared to $17 million ($17 million by the Utilities) in the first six months of 2020. The Company’s current estimate of total contributions to its pension and other postretirement benefit plans in 2021 is $52 million ($51 million by the Utilities, $1 million by HEI and nil by ASB), compared to $71 million ($70 million by the Utilities, $1 million by HEI and nil by ASB) in 2020. In addition, the Company expects to pay directly $3 million ($1 million by the Utilities) of benefits in 2021, compared to $2 million ($1 million by the Utilities) paid in 2020. The components of net periodic pension costs (NPPC) and net periodic benefit costs (NPBC) for HEI consolidated and Hawaiian Electric consolidated were as follows: Three months ended June 30 Six months ended June 30 Pension benefits Other benefits Pension benefits Other benefits 2021 2020 2021 2020 2021 2020 2021 2020 (in thousands) HEI consolidated Service cost $ 20,465 $ 18,362 $ 705 $ 631 $ 40,929 $ 36,725 $ 1,410 $ 1,262 Interest cost 18,800 20,164 1,569 1,856 37,601 40,327 3,138 3,711 Expected return on plan assets (33,068) (28,465) (3,232) (3,039) (66,135) (56,931) (6,465) (6,077) Amortization of net prior period (gain)/cost — 2 (384) (441) — 5 (767) (881) Amortization of net actuarial losses 1 8,431 8,058 44 51 9,987 16,115 298 101 Net periodic pension/benefit cost (return) 14,628 18,121 (1,298) (942) 22,382 36,241 (2,386) (1,884) Impact of PUC D&Os 5,513 6,261 1,176 777 16,680 12,523 2,146 1,554 Net periodic pension/benefit cost (adjusted for impact of PUC D&Os) $ 20,141 $ 24,382 $ (122) $ (165) $ 39,062 $ 48,764 $ (240) $ (330) Hawaiian Electric consolidated Service cost $ 19,993 $ 17,891 $ 698 $ 625 $ 39,987 $ 35,782 $ 1,397 $ 1,251 Interest cost 17,531 18,715 1,504 1,781 35,062 37,430 3,008 3,563 Expected return on plan assets (31,367) (26,857) (3,182) (2,990) (62,735) (53,712) (6,364) (5,980) Amortization of net prior period (gain)/cost — 3 (382) (439) — 5 (765) (879) Amortization of net actuarial losses 1 8,212 7,369 43 51 10,771 14,737 293 102 Net periodic pension/benefit cost (return) 14,369 17,121 (1,319) (972) 23,085 34,242 (2,431) (1,943) Impact of PUC D&Os 5,513 6,261 1,176 777 16,680 12,523 2,146 1,554 Net periodic pension/benefit cost (adjusted for impact of PUC D&Os) $ 19,882 $ 23,382 $ (143) $ (195) $ 39,765 $ 46,765 $ (285) $ (389) 1 Six months ended June 30, 2021 amounts include the one-time cumulative impact of the change in accounting principle for the plans’ fixed income securities from the calculated market-related value method to the fair value method, which was recorded in the first quarter of 2021. HEI consolidated recorded retirement benefits expense of $23 million ($23 million by the Utilities) in the first six months of 2021 and $31 million ($29 million by the Utilities) in the first six months of 2020 and charged the remaining net periodic benefit cost primarily to electric utility plant. Effective January 1, 2021, the Company adopted a change in accounting principle for the plans’ fixed income securities from the calculated market-related value method to the fair value method in the calculation of the expected return on plan assets component of NPPC and NPBC. The remaining plan assets continue to use the calculated market-related value methodology. The Company considers the fair value approach to be preferable for its fixed-income securities portfolio because it results in a current reflection of the changes in the value of plan assets in a way similar to the obligations it is intended to hedge. The Company evaluated the effect of this change in accounting principle and deemed it to be immaterial to the historical financial statements of the Company and Hawaiian Electric and, therefore, did not account for the change retrospectively and recorded the cumulative effects from the change in accounting principle in earnings for non-Utility businesses in the first quarter of 2021. Amounts related to the Utilities were reflected as adjustments to regulatory assets as appropriate, consistent with the expected regulatory treatment as described in the following paragraph. The Utilities have implemented pension and OPEB tracking mechanisms under which all of their retirement benefit expenses (except for executive life and nonqualified pension plan expenses) determined in accordance with GAAP are recovered over time. Under the tracking mechanisms, any actual costs determined in accordance with GAAP that are over/under amounts allowed in rates are charged/credited to a regulatory asset/liability. The regulatory asset/liability for each utility will then be amortized over 5 years beginning with the respective utility’s next rate case. Defined contribution plans information. For the first six months of 2021 and 2020, the Company’s expenses for its defined contribution plans under the Hawaiian Electric Industries Retirement Savings Plan (HEIRSP) and the ASB 401(k) Plan were $3.2 million and $3.7 million, respectively, and cash contributions were $3.2 million and $4.6 million, respectively. For the first six months of 2021 and 2020, the Utilities’ expenses and cash contributions for its defined contribution plan under the HEIRSP were $1.5 million and $1.4 million, respectively.

Share-based Payment Arrangement [Abstract]
Share-based compensation	Share-based compensation Under the 2010 Equity and Incentive Plan, as amended, HEI can issue shares of common stock as incentive compensation to selected employees in the form of stock options, stock appreciation rights, restricted shares, restricted stock units, performance shares and other share-based and cash-based awards. The 2010 Equity and Incentive Plan (original EIP) was amended and restated effective March 1, 2014 (EIP) and an additional 1.5 million shares were added to the shares available for issuance under these programs. As of June 30, 2021, approximately 2.9 million shares remained available for future issuance under the terms of the EIP, assuming recycling of shares withheld to satisfy minimum statutory tax liabilities relating to EIP awards, including an estimated 0.8 million shares that could be issued upon the vesting of outstanding restricted stock units and the achievement of performance goals for awards outstanding under long-term incentive plans (assuming that such performance goals are achieved at maximum levels). Under the 2011 Nonemployee Director Stock Plan (2011 Director Plan), HEI can issue shares of common stock as compensation to nonemployee directors of HEI, Hawaiian Electric and ASB. In June 2019, an additional 300,000 shares were made available for issuance under the 2011 Director Plan. As of June 30, 2021, there were 244,843 shares remaining available for future issuance under the 2011 Director Plan. Share-based compensation expense and the related income tax benefit were as follows: Three months ended June 30 Six months ended June 30 (in millions) 2021 2020 2021 2020 HEI consolidated Share-based compensation expense 1 $ 2.9 $ 2.4 $ 5.5 $ 4.1 Income tax benefit 0.5 0.4 1.0 0.7 Hawaiian Electric consolidated Share-based compensation expense 1 0.9 0.4 2.0 1.2 Income tax benefit 0.2 0.1 0.4 0.2 1 For the three and six months ended June 30, 2021 and 2020, the Company has not capitalized any share-based compensation. Stock awards. HEI granted HEI common stock to nonemployee directors under the 2011 Director Plan as follows: Three months ended June 30 Six months ended June 30 (dollars in millions) 2021 2020 2021 2020 Shares granted 29,320 35,632 29,320 36,100 Fair value $ 1.2 $ 1.3 $ 1.2 $ 1.3 Income tax benefit 0.3 0.3 0.3 0.3 The number of shares issued to each nonemployee director of HEI, Hawaiian Electric and ASB is determined based on the closing price of HEI common stock on the grant date. Restricted stock units. Information about HEI’s grants of restricted stock units was as follows: Three months ended June 30 Six months ended June 30 2021 2020 2021 2020 Shares (1) Shares (1) Shares (1) Shares (1) Outstanding, beginning of period 236,191 $ 37.91 203,441 $ 40.67 193,939 $ 40.89 207,641 $ 35.36 Granted 4,894 44.61 916 37.90 132,492 34.37 78,595 47.99 Vested (292) 38.77 — — (79,280) 38.51 (77,719) 34.19 Forfeited (11,018) 38.74 — — (17,376) 40.01 (4,160) 35.81 Outstanding, end of period 229,775 $ 38.02 204,357 $ 40.65 229,775 $ 38.02 204,357 $ 40.65 Total weighted-average grant-date fair value of shares granted (in millions) $ 0.2 $ — $ 4.6 $ 3.8 (1) Weighted-average grant-date fair value per share based on the average price of HEI common stock on the date of grant. For the six months ended June 30, 2021 and 2020, total restricted stock units and related dividends that vested had a fair value of $3.0 million and $4.2 million, respectively, and the related tax benefits were $0.6 million and $0.7 million, respectively. As of June 30, 2021, there was $7.3 million of total unrecognized compensation cost related to the nonvested restricted stock units. The cost is expected to be recognized over a weighted-average period of 2.4 years. Long-term incentive plan payable in stock. The 2019-2021, 2020-2022 and 2021-2023 long-term incentive plans (LTIP) provide for performance awards under the EIP of shares of HEI common stock based on the satisfaction of performance goals, including a market condition goal. The number of shares of HEI common stock that may be awarded is fixed on the date the grants are made, subject to the achievement of specified performance levels and calculated dividend equivalents. The potential payout varies from 0% to 200% of the number of target shares, depending on the achievement of the goals. The market condition goal is based on HEI’s total shareholder return (TSR) compared to the Edison Electric Institute Index over the relevant three-year period. The other performance condition goals relate to EPS growth, return on average common equity (ROACE), renewable portfolio standards, Hawaiian Electric’s net income growth, ASB’s efficiency ratio and strategic initiatives and Pacific Current’s EBITDA growth and return on average invested capital. LTIP linked to TSR . Information about HEI’s LTIP grants linked to TSR was as follows: Three months ended June 30 Six months ended June 30 2021 2020 2021 2020 Shares (1) Shares (1) Shares (1) Shares (1) Outstanding, beginning of period 100,053 $ 42.89 90,616 $ 42.08 89,222 $ 42.10 96,402 $ 39.62 Granted 1,533 41.12 — — 45,743 41.12 24,630 48.62 Vested (issued or unissued and cancelled) — — — — (32,355) 38.20 (29,409) 39.51 Forfeited (10,427) 42.82 — — (11,451) 43.10 (1,007) 41.72 Outstanding, end of period 91,159 $ 42.87 90,616 $ 42.08 91,159 $ 42.87 90,616 $ 42.08 Total weighted-average grant-date fair value of shares granted (in millions) $ 0.1 $ — $ 1.9 $ 1.2 (1) Weighted-average grant-date fair value per share determined using a Monte Carlo simulation model. The grant date fair values of the shares were determined using a Monte Carlo simulation model utilizing actual information for the common shares of HEI and its peers for the period from the beginning of the performance period to the grant date and estimated future stock volatility of HEI and its peers over the remaining three-year performance period. The expected stock volatility assumptions for HEI and its peer group were based on the three-year historic stock volatility. A dividend assumption is not required for the Monte Carlo simulation because the grant payout includes dividend equivalents and projected returns include the value of reinvested dividends. The following table summarizes the assumptions used to determine the fair value of the LTIP awards linked to TSR and the resulting fair value of LTIP awards granted: 2021 2020 Risk-free interest rate 0.19 % 1.39 % Expected life in years 3 3 Expected volatility 29.9 % 13.1 % Range of expected volatility for Peer Group 25.6% to 102.9% 13.6% to 95.4% Grant date fair value (per share) $41.12 $48.62 For the six months ended June 30, 2021 and 2020, total vested LTIP awards linked to TSR and related dividends had a fair value of $0.8 million and $2.6 million, respectively, and the related tax benefits were $0.2 million and $0.4 million, respectively. As of June 30, 2021, there was $2.1 million of total unrecognized compensation cost related to the nonvested performance awards payable in shares linked to TSR. The cost is expected to be recognized over a weighted-average period of 1.6 years. LTIP awards linked to other performance conditions . Information about HEI’s LTIP awards payable in shares linked to other performance conditions was as follows: Three months ended June 30 Six months ended June 30 2021 2020 2021 2020 Shares (1) Shares (1) Shares (1) Shares (1) Outstanding, beginning of period 335,702 $ 38.04 336,344 $ 39.64 220,715 $ 41.03 403,768 $ 35.15 Granted 6,133 44.49 — — 182,977 34.33 98,522 48.10 Vested — — — — (43,155) 34.12 (135,804) 33.48 Increase above target (cancelled) 15,881 42.92 (38,821) 34.12 1,277 31.71 (64,932) 34.12 Forfeited (41,711) 38.27 — — (45,809) 38.82 (4,031) 39.67 Outstanding, end of period 316,005 $ 38.38 297,523 $ 40.37 316,005 $ 38.38 297,523 $ 40.37 Total weighted-average grant-date fair value of shares granted (at target performance levels) (in millions) $ 0.3 $ — $ 6.3 $ 4.7 (1) Weighted-average grant-date fair value per share based on the average price of HEI common stock on the date of grant. For the six months ended June 30, 2021 and 2020, total vested LTIP awards linked to other performance conditions and related dividends had a fair value of $1.7 million and $7.6 million, respectively, and the related tax benefits were $0.4 million and $1.2 million, respectively. As of June 30, 2021, there was $6.7 million of total unrecognized compensation cost related to the nonvested shares linked to performance conditions other than TSR. The cost is expected to be recognized over a weighted-average period of 1.8 years.

Income Tax Disclosure [Abstract]
Income taxes	Income taxes The Company’s and the Utilities’ effective tax rates (combined federal and state income tax rates) were each 21%, for the six months ended June 30, 2021. These rates differed from the combined statutory rates, due primarily to the Utilities’ amortization of excess deferred income taxes related to the provision in the Tax Act that lowered the federal income tax rate from 35% to 21%, the tax benefits derived from the low income housing tax credit investments and the non-taxability of the bank-owned life insurance income. The Company’s and the Utilities’ effective tax rates were 17% and 19%, respectively, for the six months ended June 30, 2020. In August 2020, the Internal Revenue Service notified the Company that its 2017 and 2018 income tax returns would be examined. The Company was previously audited every year through 2011, at which time the IRS changed their internal policies regarding audit frequency. The Company has received several initial requests for general tax return information and has responded or is in the process of responding to such requests.

Fair Value Disclosures [Abstract]
Fair value measurements	Fair value measurements Fair value measurement and disclosure valuation methodology. The following are descriptions of the valuation methodologies used for assets and liabilities recorded at fair value and for estimating fair value for financial instruments not carried at fair value: Short-term borrowings—other than bank . The carrying amount of short-term borrowings approximated fair value because of the short maturity of these instruments. Investment securities . The fair value of ASB’s investment securities is determined quarterly through pricing obtained from independent third-party pricing services or from brokers not affiliated with the trade. Non-binding broker quotes are infrequent and generally occur for new securities that are settled close to the month-end pricing date. The third-party pricing vendors ASB uses for pricing its securities are reputable firms that provide pricing services on a global basis and have processes in place to ensure quality and control. The third-party pricing services use a variety of methods to determine the fair value of securities that fall under Level 2 of ASB’s fair value measurement hierarchy. Among the considerations are quoted prices for similar securities in an active market, yield spreads for similar trades, adjustments for liquidity, size, collateral characteristics, historic and generic prepayment speeds, and other observable market factors. To enhance the robustness of the pricing process, ASB will on a quarterly basis compare its standard third-party vendor’s price with that of another third-party vendor. If the prices are within an acceptable tolerance range, the price of the standard vendor will be accepted. If the variance is beyond the tolerance range, an evaluation will be conducted by ASB and a challenge to the price may be made. Fair value in such cases will be based on the value that best reflects the data and observable characteristics of the security. In all cases, the fair value used will have been independently determined by a third-party pricing vendor or non-affiliated broker. The fair value of the mortgage revenue bonds is estimated using a discounted cash flow model to calculate the present value of future principal and interest payments and, therefore is classified within Level 3 of the valuation hierarchy. Loans held for sale . Residential and commercial loans are carried at the lower of cost or market and are valued using market observable pricing inputs, which are derived from third party loan sales and, therefore, are classified within Level 2 of the valuation hierarchy. Loans held for investment . Fair value of loans held for investment is derived using a discounted cash flow approach which includes an evaluation of the underlying loan characteristics. The valuation model uses loan characteristics which includes product type, maturity dates and the underlying interest rate of the portfolio. This information is input into the valuation models along with various forecast valuation assumptions including prepayment forecasts, to determine the discount rate. These assumptions are derived from internal and third party sources. Since the valuation is derived from model-based techniques, ASB includes loans held for investment within Level 3 of the valuation hierarchy. Collateral dependent loans . Collateral dependent loans have been adjusted to fair value. When a loan is identified as collateral dependent, the Company measures the impairment using the current fair value of the collateral, less selling costs. Depending on the characteristics of a loan, the fair value of collateral is generally estimated by obtaining external appraisals, but in some cases, the value of the collateral may be estimated as having little or no value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. If it is determined that the value of the collateral dependent loan is less than its recorded investment, the Company recognizes this impairment and adjusts the carrying value of the loan to fair value through the allowance for credit losses. Real estate acquired in settlement of loans . Foreclosed assets are carried at fair value (less estimated costs to sell) and are generally based upon appraisals or independent market prices that are periodically updated subsequent to classification as real estate owned. Such adjustments typically result in a Level 3 classification of the inputs for determining fair value. ASB estimates the fair value of collateral-dependent loans and real estate owned using the sales comparison approach. Mortgage servicing rights . MSRs are capitalized at fair value based on market data at the time of sale and accounted for in subsequent periods at the lower of amortized cost or fair value. MSRs are evaluated for impairment at each reporting date. ASB's MSRs are stratified based on predominant risk characteristics of the underlying loans including loan type and note rate. For each stratum, fair value is calculated by discounting expected net income streams using discount rates that reflect industry pricing for similar assets. Expected net income streams are estimated based on industry assumptions regarding prepayment expectations and income and expenses associated with servicing residential mortgage loans for others. Impairment is recognized through a valuation allowance for each stratum when the carrying amount exceeds fair value, with any associated provision recorded as a component of loan servicing fees included in "Revenues - bank" in the consolidated statements of income. A direct write-down is recorded when the recoverability of the valuation allowance is deemed to be unrecoverable. ASB compares the fair value of MSRs to an estimated value calculated by an independent third-party. The third-party relies on both published and unpublished sources of market related assumptions and its own experience and expertise to arrive at a value. ASB uses the third-party value only to assess the reasonableness of its own estimate. ASB includes MSRs within Level 3 of the valuation hierarchy. Time deposits . The fair value of fixed-maturity certificates of deposit was estimated by discounting the future cash flows using the rates currently offered for FHLB advances of similar remaining maturities. Deposit liabilities are classified in Level 2 of the valuation hierarchy. Other borrowings . For advances and repurchase agreements, fair value is estimated using quantitative discounted cash flow models that require the use of interest rate inputs that are currently offered for advances and repurchase agreements of similar remaining maturities. The majority of market inputs are actively quoted and can be validated through external sources, including broker market transactions and third party pricing services. Long-term debt—other than bank . Fair value of fixed-rate long-term debt—other than bank was obtained from third-party financial services providers based on the current rates offered for debt of the same or similar remaining maturities and from discounting the future cash flows using the current rates offered for debt of the same or similar risks, terms, and remaining maturities. The carrying amount of floating rate long-term debt—other than bank approximated fair value because of the short-term interest reset periods. Long-term debt—other than bank is classified in Level 2 of the valuation hierarchy. Interest rate lock commitments (IRLCs) . The estimated fair value of commitments to originate residential mortgage loans for sale is based on quoted prices for similar loans in active markets. IRLCs are classified as Level 2 measurements. Forward sales commitments . To be announced (TBA) mortgage-backed securities forward commitments are classified as Level 1, and consist of publicly-traded debt securities for which identical fair values can be obtained through quoted market prices in active exchange markets. The fair values of ASB’s best efforts and mandatory delivery loan sale commitments are determined using quoted prices in the market place that are observable and are classified as Level 2 measurements. The following table presents the carrying or notional amount, fair value and placement in the fair value hierarchy of the Company’s financial instruments.

The Company estimates the fair value by using a discounted cash flow model to calculate the present value of estimated future principal and interest payments. The unobservable input used in the fair value measurement is the weighted average discount rate. As of June 30, 2021, the weighted average discount rate was 2.05%, which was derived by incorporating a credit spread over the one month LIBOR rate. Significant increases (decreases) in the weighted average discount rate could result in a significantly lower (higher) fair value measurement. Fair value measurements on a nonrecurring basis. Certain assets and liabilities are measured at fair value on a nonrecurring basis and therefore are not included in the tables above. These measurements primarily result from assets carried at the lower of cost or fair value or from impairment of individual assets. The carrying value of assets measured at fair value on a nonrecurring basis were as follows: Fair value measurements using (in thousands) Balance Level 1 Level 2 Level 3 June 30, 2021 Loans $ 204 $ — $ — $ 204 December 31, 2020 Loans 387 — — 387 Mortgage servicing rights 3,001 — — 3,001 For the six months ended June 30, 2021 and 2020, there were no adjustments to fair value for ASB’s loans held for sale. The following table presents quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a nonrecurring basis: Significant unobservable input value (1) ($ in thousands) Fair value Valuation technique Significant unobservable input Range Weighted June 30, 2021 Residential $ 125 Fair value of property or collateral Appraised value less selling cost N/A (2) N/A (2) Home equity lines of credit 79 Fair value of collateral Appraised value less selling cost N/A (2) N/A (2) December 31, 2020 Commercial loan $ 387 Fair value of collateral Appraised value less selling cost N/A (2) N/A (2) Mortgage servicing rights 3,001 Discounted cash flow Prepayment speed 15% - 22% 22 % Discount rate 9.3 % (1) Represents percent of outstanding principal balance.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentationThe accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) for interim financial information, the instructions to SEC Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In preparing the unaudited condensed consolidated financial statements, management is required 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 balance sheet and the reported amounts of revenues and expenses for the period. Actual results could differ significantly from those estimates.
Recent accounting pronouncements	Recent accounting pronouncements. Income Taxes . In December 2019, Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which removes specific exceptions to the general principles in Topic 740, improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP under certain situations. ASU No. 2019-12 is effective for public business entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The Company adopted the ASU as of January 1, 2021 with no material impact on its consolidated financial statements and related disclosures. Leases . On July 19, 2021 FASB issued ASU No. 2021-05, “Leases (Topic 842): Lessors–Certain Leases with Variable Lease Payments.” The ASU allows lessors to treat sales-type leases with variable payments to be classified as operating leases if the sales-type lease treatment under Topic 842 would result in a selling loss at lease commencement (day-one loss). The Company plans to early adopt ASU No. 2021-05 as of September 30, 2021 retrospectively to leases that commenced on or after the adoption of ASU No. 2016-02. The impact of the adoption of ASU No. 2021-05 on the Company’s consolidated financial statements is not expected to be material.
Troubled debt restructurings	Troubled debt restructurings. A loan modification is deemed to be a TDR when the borrower is determined to be experiencing financial difficulties and ASB grants a concession it would not otherwise consider. The allowance for credit losses on TDR loans that do not share risk characteristics are individually evaluated based on the present value of expected future cash flows discounted at the loan’s effective original contractual rate or based on the fair value of collateral less cost to sell. The financial impact of the estimated loss is an increase to the allowance associated with the modified loan. When available information confirms that specific loans or portions thereof are uncollectible (confirmed losses), these amounts are charged off against the allowance for credit losses.
