relative to the reconciliation of default electric service rates.

Removed the requirement that residential and small commercial default service must use only fixed-price contracts and not involve real-time or day-ahead ISO New England market purchases (except when fixed-price contracts of sufficient size cannot be obtained).

Added a broad prohibition: no reconciliation of actual and estimated wholesale power supply costs for default service may be recovered through a non-bypassable charge, except in extraordinary circumstances found by the commission through an adjudicative proceeding.

Removed the specific amortization requirement that reconciliations from real-time or day-ahead market purchases be spread over no more than 2 consecutive default service rate cycles beginning with the February 2027 cycle.

The bill's title and scope shifted from regulating procurement methods (fixed-price contracts, market purchase limits) to governing only the recovery mechanism for cost reconciliations (non-bypassable charges).

Mandates that default service for residential and small commercial customers must use fixed-price contracts, with real-time or day-ahead ISO New England market purchases permitted only to fill gaps when fixed-price contracts of sufficient size cannot be obtained.

Replaced the general 'true-up' language with a more specific reconciliation mechanism: over/underpayments from real-time or day-ahead purchases must be recovered only through future default service rate changes approved by the commission, and must be amortized over no more than 2 consecutive rate cycles beginning February 2027.

Effective date changed from 60 days after passage to immediately upon passage.

The bill title/header changed from 'AS AMENDED BY THE SENATE' to 'VERSION ADOPTED BY BOTH BODIES,' reflecting that the bill passed both chambers and is ready for gubernatorial action.
