HI HB903

Amends the definition of "renewable portfolio standard" for electric utilities to measure renewable energy generation divided by total electrical energy generation (instead of renewable energy sales divided by total sales), providing a more accurate calculation of renewable energy penetration in Hawaii.

Establishes new renewable portfolio standards for gas utility companies that sell gas for grid-connected electricity generation, requiring 100% renewable gas by December 31, 2045, mirroring electric utility targets.

Adds new sections to Hawaii Revised Statutes (269-A, 269-B, 269-C) defining renewable gas sources (biogas, biomass, biofuels, hydrogen from renewable sources) and establishing reporting requirements, penalties, and waiver procedures for gas utilities.

Allows gas utilities and their affiliates to aggregate renewable portfolios and recover costs through automatic rate adjustment clauses without requiring rate case filings.

Clarifies that events beyond a utility's reasonable control (weather damage, natural disasters, equipment failure, inability to acquire cost-effective renewable resources) may excuse failure to meet renewable portfolio standards, subject to Public Utilities Commission approval.
