What it would mean nearby

Base rate freeze through 2028 (docket 44280) holds base rates flat from July 2025. Fuel and storm riders are separate and can still move. 2026 fuel and storm cost settlement (docket 44280, 56765) takes about $4.04 a month off a typical bill from June 2026. The December 2025 certification of about 9,885 MW of new generation for data center load came with a promise of at least $8.50 a month of downward pressure on a typical bill in 2029 through 2031, because large customers are meant to carry more of the cost. Consumer groups warned it could instead add around $20 a month if the projected data center demand does not show up.
