SB 4 Connecticut Senate · 2025 Regular Session

AN ACT CONCERNING ENERGY AFFORDABILITY, ACCESS AND ACCOUNTABILITY.

This bill authorizes Connecticut to issue up to $125 million in state bonds (for fiscal years 2026-2027) to reduce energy cost protections for low-income households to pre-pandemic levels (2016-2020). It also allocates $50 million in bonds ($30M for 2026, $20M for 2027) to fund electric vehicle charging infrastructure and customer wiring upgrades. The funds will support programs administered by the Public Utilities Regulatory Authority, including residential EV charging for households at or below 300% of the federal poverty level. These provisions aim to lower energy costs for vulnerable residents and expand clean energy access through specific infrastructure investments.

Committee Bill → ET Joint Favorable Substitute · 4 edits
MODERATE
The bill was renumbered from a Committee Bill to a Substitute Bill, indicating it has been revised and approved by both legislative chambers. The most significant substantive change is the addition of a new Section 2 establishing a competitive funding program for advanced nuclear reactor and offshore wind energy site readiness, which did not exist in the original Committee Bill. Additionally, Section 3 was modified to specify a $5 million funding cap for bonds, and Section 1 was restructured to clarify conditions for new nuclear power facility construction, particularly regarding high-level nuclear waste disposal requirements.
Scope change
The bill now includes new provisions for funding advanced nuclear reactor and offshore wind energy projects through grants and loans, expanding its scope beyond just regulating nuclear facility construction.
FISCAL

New Section 2 establishes a competitive funding program providing grants or loans to eligible recipients for environmental studies, infrastructure assessments, and community engagement related to advanced nuclear reactors and offshore wind facilities.

Section 3 was changed to specify a $5 million aggregate limit for state bond issuance to fund the new site readiness program.

REQUIREMENT

Section 1 was restructured to clarify that construction of new nuclear facilities requires identification and approval of high-level nuclear waste disposal technology by the US Government, with specific exemptions for facilities operating as of October 1, 2022.

TECHNICAL

Bill numbering changed from Committee Bill No. 4 to Substitute Bill No. 4, and LCO numbers were updated to reflect the legislative process progression.
