Senate Bill No. 420, titled "An Act Concerning Natural Gas and Gas Companies," proposes technical amendments to existing energy-related statutes, specifically focusing on the definition of "gas company." The bill repeals and replaces subdivision (5) of subsection (a) of section 16-1 of the 2026 supplement to the general statutes. The new definition clarifies that a "gas company" includes entities involved in the transmission or distribution of gas for sale and use for heat or power within the state. It also specifies that the term does not encompass certain entities, such as those manufacturing gas through biomass gasification plants, municipal gas utilities, or entities approved to submeter.

The bill is set to take effect on October 1, 2026, and does not have any fiscal impact on the state or municipalities. The changes are primarily technical in nature, aimed at refining the legal language surrounding gas companies without altering the fundamental operations or regulations governing them. The Energy and Technology Committee has reported the bill favorably, indicating broad support for its passage.
