HB 5472 Connecticut House · 2026 Regular Session

AN ACT CONCERNING THE SAFETY OF ENERGY GENERATION SOURCES AND ENERGY STORAGE SYSTEMS.

This bill establishes new safety reporting and emergency response requirements for energy generation and storage facilities in Connecticut. It mandates that facility operators report major incidents, such as those requiring emergency shutdowns or hospitalizations, within five days and minor shutdowns within 30 days to the Connecticut Siting Council. Starting in 2027, operators must designate an emergency contact person available to respond within one hour and post their contact information at facility entrances. Beginning in 2028, the council will annually report all incident data to the state legislature, and the council may require applicants to provide emergency services training to local firefighters at the applicant's expense.

What changed between versions

Raised Bill ET Joint Favorable Substitute · 4 edits
MODERATE
The bill was renamed from 'Raised Bill' to 'Substitute Bill' and re-referred to the Energy and Technology Committee. Substantively, the bill adds a new definition for 'minor incident,' which excludes routine maintenance shutdowns, and clarifies reporting deadlines for both major and minor incidents. It also updates the required contact titles from 'official' to 'officer' in several places.
Scope change
The bill's scope regarding incident reporting is slightly refined by explicitly excluding routine maintenance from the definition of a reportable minor incident.
DEFINITION

Added a new definition for 'minor incident' to clarify that routine maintenance shutdowns do not need to be reported.

REQUIREMENT

Added a specific requirement to report 'minor incidents' within thirty days, whereas previously only 'major incidents' had a defined reporting window.

Corrected the title of the local government representative from 'chief executive official' to 'chief executive officer' in multiple sections.

TECHNICAL

Changed the bill title from 'Raised Bill' to 'Substitute Bill' and updated the page header to reflect this change.
