"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 consider energy security, diversity, and affordability when developing the state's Energy Master Plan. It mandates that the BPU conduct detailed economic and ratepayer impact analyses for all energy generation projects before approval, including cost breakdowns for infrastructure and financial effects on ratepayers. The plan must limit intermittent energy sources (like wind and solar) to no more than 50% of the state's energy mix. All analyses must use open-source modeling, include 30 days of public comment, and be published online for 10 years. These changes directly affect energy developers, ratepayers, and the BPU's planning process.
