The Energy Facilities Siting Board (EFSB) is an independent state board that reviews proposed large energy facilities including power plants, electric transmission lines, intra-state natural gas pipelines, and natural gas storage tanks. The Department of Public Utilities (DPU) administratively supports the work of the EFSB and its staff, but the eleven-member EFSB makes its decisions independently.
Who we serve
The EFSB serves:
- Energy consumers by ensuring a reliable supply of energy at the lowest possible cost.
- Communities and residents by ensuring that approved facilities have minimized environmental impacts such as: air emissions, noise, traffic, waste, electric and magnetic fields, wetlands and water quality degradation, visual intrusions, and risks to public health and safety.
- Energy facility developers who must obtain EFSB approval to construct proposed facilities.
- Federal, state, and local agencies that are also involved in the review and permitting of proposed energy facilities.
