Amends GS 62-133.2(d) requiring the North Carolina Utilities Commission (Commission) to incorporate in its cost of fuel and fuel-related costs determination, the experienced over-recovery or under-recovery of reasonable costs of fuel and fuel related costs prudently incurred, during the test period (was, by the electric public utility), based on prudent standards set in GS 62-133.2(d1), in fixing an increment or decrement rider. Adds that the Commission cannot incorporate in this determination any fuel or fuel-related costs incurred prior to the test period. Mandates that any experienced over-recovery or under-recovery of reasonable fuel and fuel-related costs prudently incurred during the test period (previously, no “during the test period” language) will accrue interest at the commercial paper rate identified by the Federal Reserve for A2/P2 nonfinancial issuers, or reasonable successor, on a weighted average basis over the applicable time period.

Appropriates $10,000 for 2026-27 from the General Fund to the Utilities Commission to be used for purposes consistent with this act.

Effective July 1, 2026, and applies to any rate-making mechanisms filed by an electric public utility on or after that date.
