Performance-based Regulation (PBR) for the Hawaiian Electric Companies (Docket No. 2018-0088)
Background | Key Orders and Filings | Key Past Events | More Information
BACKGROUND
Following a three-year investigation, the Commission established a performance-based regulation (“PBR”) Framework to govern the Hawaiian Electric Companies. This PBR Framework includes a set of alternative regulatory mechanisms encouraging the utility to focus on performance and desired outcomes, such as increasing renewable energy, lowering costs, and improving customer service.
The PBR Framework employs four types of regulatory tools: revenue adjustment mechanisms, performance mechanisms, an innovative pilot process, and safeguards. The revenue adjustment mechanisms set the utility’s target revenues for a five-year period, which are adjusted by a formula that accounts for inflation, a customer dividend, collected revenues, and extraordinary projects. The performance mechanisms include performance incentive mechanisms (“PIMs”) that provide additional revenue opportunities if the utility meets certain performance outcomes, which are supplemented by a portfolio of scorecards and reported metrics to monitor the utility’s progress. The innovative pilot process is a framework for expedited review for pilot projects to incent innovative programs and projects. The safeguards include an Earnings Sharing Mechanism (“ESM”) to protect the utility and customers from excessive earnings or losses and a re-opener mechanism in case the entire PBR Framework (or specific parts) need to be reexamined.
The PBR Framework went into effect on June 1st, 2021 for a five-year period. During this five-year period, the parties involved with developing the PBR Framework have been collaborating through the PBR Working Group on implementation and monitoring efforts, such as the development, review, and modification of PIMs. In the final years of the five-year period, the Commission and the parties shall review the PBR Framework to determine appropriate modifications for the next iteration of the PBR Framework.

June 19, 2024 | Order No. 40852 | The Commission provided preliminary guidance regarding the comprehensive review of the Performance-Based Regulation Framework that will commence in the fourth year of the first Multi-Year Rate Period (MRP1), 2024-2025. The Commission outlined a tentative three-phase review structure: Phase 5 (July 2024-January 2025) will evaluate PBR mechanisms through facilitated collaborative processes to identify which can continue unmodified; Phase 6 (February-May 2025) will formally examine specific modifications through testimony and hearings; and Phase 7 (June 2026-December 2026) will address implementation details during an interim period. The Commission also indicated plans to re-align MRP2 to a calendar year cycle beginning January 2027, utilize PBR Guiding Principles developed in Phase 1 as evaluation tools, and consider re-basing Hawaiian Electric’s target revenues through either a consolidated rate case or PBR Rebasing Mechanism. |
