THE SENATE	S.B. NO.	2487
THIRTY-THIRD LEGISLATURE, 2026
STATE OF HAWAII

A BILL FOR AN ACT

relating to the public utilities commission.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF HAWAII:

SECTION 1. The legislature finds that, in 2018, the legislature enacted the Hawaii Ratepayer Protection Act to provide proactive protections to the State's electric utility customers. Act 5, Session Laws of Hawaii 2018 (Act 5), provided that electric utility rates would be considered just and reasonable only if they were derived from a performance-based model for determining utility revenues. Act 5 emphasized that the State should adjust electric utilities' interests to better align with customers' interests. The legislature found that there was "extraordinary urgency" for this realignment.

Act 5 directed the public utilities commission to establish a performance-based model for utility regulation and ratemaking based on performance incentives that "directly tie an electric [utility's] revenues to that utility's achievement on performance metrics and break the direct link between allowed revenues and investment levels." The intent of this performance-based model was to depart from the traditional cost‑of-service model that rewards utilities for increasing the utility's capital expenditures and bases allowed revenues on the value of the rate base, irrespective of the utility's performance. The legislature recognized that the traditional model misaligned the interests of customers and utilities because it created a possible bias toward utilities that expended capital on utility-owned projects, rather than utilities that supported more efficient or cost-effective options like customer-owned distributed energy resources or independent, third-party projects. The legislature concluded that the State needed a shift away from the traditional focus on utility costs to a more modern focus on performance.

The legislature further finds that, in response to the Hawaii Ratepayer Protection Act, the public utilities commission opened its performance-based regulation proceeding as a historic, multi-phase process that included participation from local and national experts. In December 2020, the commission established a comprehensive framework for performance-based regulation that has since been nationally recognized as a leading model. The guiding principles for this framework include a customer-centric approach, including day-one savings for customers; administrative efficiency through a simplified regulatory framework; and utility financial integrity with the opportunity to earn profits and rewards through performance. The main features of the framework include a multi-year rate period of five years, during which the utility's allowed revenues are determined not by traditional rate cases but by an objective index tied to general inflation. The utility's profits are driven largely by its ability to capture cost savings and efficiencies. The framework also includes performance incentive mechanisms to reward or penalize a utility based on its performance on public interest priorities like reliability, accelerated progress toward renewable energy, and improved customer service. The commission emphasized that, with the transition away from traditional cost-of-service regulation, customers would benefit from lower utility costs.

In establishing the performance-based framework, the public utilities commission recognized the need for a transformative and lasting shift away from cost-of-service regulation. The commission made clear that, after the five-year rate control period, the commission anticipated continuing to refine the performance-based framework and did not envision returning to cost-of-service regulation. However, now that the end of the rate control period is approaching, the legislature is concerned about the integrity of the performance-based framework and the commission's compliance with the Hawaii Ratepayer Protection Act. For example, last year, the commission adopted the utility's proposal to initiate a traditional, cost-of-service rate to "re-base" the utility's allowed revenues using its projected increased costs. This cost-based rebasing of revenues backtracks on the progress and reforms the State has made and violates the commission's previous commitment not to return to cost-of-service regulation.

The legislature is also aware that the public utilities commission has insisted on requiring a "forward test year" approach to the rate case, in which a utility requests a rate increase based on future cost projections, rather than the historical cost trends that have been controlled under the performance-based framework. This return to forecasted cost‑of‑service ratemaking encourages utilities to make "wish lists" of capital projects to boost utility profits, thereby inflating customer rates. However, the predominant practice in rate cases is to use historical costs adjusted for known and measurable changes, rather than forecasted future costs, as the basis for regulatory rate analyses. Jurisdictions using forecasted costs instead of historical costs end up paying substantially higher rates.

The legislature recognizes that the public utilities commission has expressed the commission's belief that it is constrained by existing legal provisions to follow certain traditional cost-bound methods, notwithstanding the mandates of the Hawaii Ratepayer Protection Act. As a result, the commission is inviting a return to "cost-plus" ratemaking that threatens to undermine the benefits and progress achieved under the performance-based framework. This poses the risk of significant rate increases for customers.

Based on this stance by the public utilities commission, and the risk of rate increases for customers, the legislature believes that further clarification and guidance are needed to ensure that the commission upholds the legislature's original intent under the Hawaii Ratepayer Protection Act and continues the progress made under the commission's performance-based regulatory framework. These clarifications will help ensure that both electric utilities and ratepayers will continue to benefit from the utilities' improved performance, lower costs, and lower rates.

Accordingly, the purpose of this Act is to provide clarification and guidance by:

(1) Clarifying that, for the purposes of regulating electric utility rates, "performance-based incentives" include revenue adjustment mechanisms; cost control mechanisms, such as the multi-year rate period; rewards for superior performance; and penalties for subpar performance;

(2) Confirming that the public utilities commission may adopt alternative ratemaking procedures to establish electric utility rates and performance-based incentives that fulfill the requirements of section 269-16.1, Hawaii Revised Statutes; and

(3) Requiring the commission to apply a presumption in favor of considering historical cost trends and external indices that reflect incentives to control costs if resetting an electric utility's allowed revenues based on consideration of the utility's costs.

SECTION 2. This Act shall be known and may be cited as the Hawaii Ratepayer Protection Act of 2026.

SECTION 3. Section 269-16.1, Hawaii Revised Statutes, is amended to read as follows:

"§269-16.1 [Performance incentive and penalty mechanisms] Performance-based incentives; regulation of electric utility rates. (a) On or before January 1, [2020,] 2027, the public utilities commission shall establish [performance] performance‑based incentives, including revenue adjustment mechanisms, cost control mechanisms, and reward and penalty mechanisms, that directly tie an electric [[]utility's[]] revenues to that utility's [achievement on] performance [metrics] and break the direct link between allowed revenues and investment levels. The [performance] performance-based incentives [and penalty mechanisms], as may be amended by the public utilities commission from time to time, shall apply to the regulation of electric utility rates under [section 269-16.] this chapter.

(b) Notwithstanding any law to the contrary, including the ratemaking procedures described in section 269-16, the public utilities commission may adopt, by commission order, alternative ratemaking procedures to establish electric utility rates and performance-based incentives for purposes of subsection (a); provided that the rates shall be derived from a performance‑based model for determining utility revenues.

(c) If resetting an electric utility's allowed revenues based on consideration of the utility's costs, the commission shall apply a presumption in favor of considering historical cost trends and external indices that reflect incentives to control costs, rather than relying on a forward test period.

[(b)] (d) In developing [performance incentive and penalty mechanisms,] performance-based incentives, the public utilities commission's review of electric utility performance shall consider[, but not be limited to,] the [following]:

(1) [The economic] Economic incentives and cost-recovery mechanisms described in section 269-6(e);

(2) Volatility and affordability of electric rates and customer electric bills;

(3) [Electric service reliability;] Reliability of electric service;

(4) [Customer] Level of customer engagement and satisfaction, including customer options for managing electricity costs;

(5) [Access to] Accessibility of utility system information, including [but not limited to public access to] electric system planning data [and], aggregated customer energy use data [and individual access to], and granular information about an individual customer's own energy use data;

(6) Rapid integration of renewable energy sources, including quality interconnection of customer-sited resources; and

(7) Timely execution of competitive procurement, third‑party interconnection, and other business processes.

[(c)] (e) This section shall not apply to a member-owned cooperative electric utility."

SECTION 4. Statutory material to be repealed is bracketed and stricken. New statutory material is underscored.

SECTION 5. This Act shall take effect upon its approval.

INTRODUCED BY:
