PURA's interim decision reset six CL&P charges (public benefits, transmission and delivery trackers) for May 2026 to April 2027. Lower public-benefits costs, mainly credits from the Millstone and Seabrook nuclear contracts and state bonding, cut residential rates by about 4.3 cents/kWh (about $30 a month per PURA). It also added $100 million of storm-cost recovery.

Utility's stated reasons

  • nuclear contract (Millstone/Seabrook) credits
  • state bond funding of public-benefit programs
  • lower hardship and arrearage costs
