"Energy Security and Affordability Act"; requires BPU to consider energy security, diversity, and affordability when preparing Energy Master Plan and perform economic and ratepayer impact analysis of energy generation projects and Energy Master Plan.

The "Energy Security and Affordability Act" (S 1900) requires New Jersey's Board of Public Utilities (BPU) to prioritize energy security, diversity, and affordability when updating the state's Energy Master Plan. It mandates the BPU to conduct detailed economic and ratepayer impact analyses for all energy generation projects and the Master Plan itself, including cost breakdowns, infrastructure expenses, and public comment periods. These analyses must be published online for 10 years using open-source modeling tools. The bill directly affects ratepayers (utility customers) and energy developers by ensuring decisions consider financial impacts and public input before project approvals.
