Requires energy usage plan for proposed artificial intelligence data centers and cryptocurrency mining facilities; requires all electricity for artificial intelligence data centers and cryptocurrency mining facilities to be derived from new clean energy sources.*

S 4143 requires new artificial intelligence (AI) data centers and cryptocurrency mining facilities in New Jersey to submit an energy usage plan to the Board of Public Utilities (BPU) before connecting to the grid. The plan must detail how the facility will use 100% new clean energy (like solar/wind or nuclear power) for all electricity, minimize cooling energy, optimize water use, and reuse waste heat. This requirement only applies once the BPU confirms a majority of states in the PJM grid region (which includes New Jersey) have similar rules. The bill directly affects developers seeking local approval for these facilities by mandating clean energy compliance before construction begins.
