"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.

This bill requires New Jersey's Board of Public Utilities (BPU) to prioritize energy security, diversity, and affordability when creating the state's Energy Master Plan. It mandates the BPU to limit variable energy sources (like solar and wind) to no more than 50% of the state's energy portfolio and conduct detailed economic and ratepayer impact analyses for all major energy projects and the Master Plan itself. These analyses must break down costs, include public comment periods, and be published online for 10 years. The bill directly affects the BPU, energy companies seeking project approvals, and ratepayers through these new transparency and analysis requirements.
