Requires electric public utilities to submit transmission project proposal to BPU for approval.

S 4575 requires New Jersey electric public utilities to submit transmission project proposals to the Board of Public Utilities (BPU) for approval before starting new or modified transmission lines. Proposals must detail environmental and safety impacts, all project costs, how the project meets a public need (such as improved reliability or lower consumer costs), and cheaper alternatives. The BPU must review proposals within 90 days and approve them if they are reasonable, in the public interest, and cost-effective. This bill directly affects utilities that transmit electricity in New Jersey, aiming to ensure projects are necessary and cost-efficient.
