- rPlus Energies announced commercial operations for the Green River Energy Center after a commissioning ceremony held June 22, 2026, marking the start of power delivery from 400 MW of photovoltaic panels paired with 400 MW/1,600 MWh of battery storage.

- Major suppliers and contractors include Elite Solar for PV modules, Tesla for the battery system, Sundt Construction as EPC, and Nextpower for trackers, with partners stressing substantial U.S. manufacturing and supply-chain sourcing.
