Hawaiian Electric Industries, Inc. (HEI) filed a Current Report on Form 8-K on September 8, 2026, disclosing an investor presentation intended for use in meetings beginning on that date. The presentation details the company’s operational status, financial metrics, and strategic initiatives regarding its regulated utility subsidiaries in Hawaii.
The presentation highlights that the utility operates across five separate grids serving approximately 95% of Hawaii’s population. As of December 31, 2025, the company reports a total rate base of approximately $4 billion and a market capitalization of $1.9 billion. The utility maintains a vertically integrated structure with a unique Performance Based Regulation (PBR) framework designed to provide stable, predictable revenues. This framework includes an Annual Revenue Adjustment (ARA) based on the Gross Domestic Product Price Index (GDPPI); the October 2025 forecast for 2026 was set at 2.8%.
A significant portion of the filing addresses the impact of recent severe weather events. The company reports that Hurricane Lala caused extensive damage across the service territories from August 14 to August 16, 2026. Although outages peaked at over 40% of customer accounts, Hawaiian Electric crews restored service to more than 95% of affected customers by August 19. The utility estimates the total operating and maintenance (O&M) impact from Hurricane Lala at $15 million to $20 million, with combined costs from the Kona Low storms totaling $25 million to $30 million. Additionally, the company estimates capital expenditures related to storm damage at $30 million to $40 million. HEI states it is planning to file a cost deferral application in 2026 to recover these costs, subject to review and approval by the Public Utilities Commission (PUC).
The filing also outlines the status of an alternative rate rebasing proceeding. The company submitted a rebasing application in July 2026 and proposes an interim decision by the PUC in December 2026, which would allow new rates to take effect on January 1, 2027. The company has proposed a phased increase totaling $169.8 million for 2027 and 2028. The proposal includes a modification to the GDPPI adjustment to use actual inflation rather than forecasts and aims to expand the scope of the Exceptional Project Recovery Mechanism (EPRM). Furthermore, the company is advancing Phase 6 of the PBR proceeding to examine modifications to Performance Incentive Mechanisms (PIMs) and other revenue opportunities.
Strategic spending initiatives are detailed, with the company targeting over $400 million in spending from 2025 through 2027 to reduce wildfire risk and enhance grid resilience. The presentation notes that only 6% of the utility’s total transmission and distribution miles are located in high wildfire risk areas, compared to over 25% for utilities in six California states. The company also discusses affordability strategies, noting that in 2025, Hawaii’s total household energy burden was 3.24% of monthly household income, ranking fourth lowest among U.S. states.
