Senate committee hears CUC plan targeting 40% renewables with staged solar and battery projects

The Senate Public Utilities, Transportation and Communications Committee heard an informational presentation Feb. 20 from GHD and the Commonwealth Utilities Corporation (CUC) on an updated integrated resource plan (IRP) that aims to raise renewable energy penetration to about 40 percent across Saipan, Tinian and Rota.

"The main goal of the IRP update is to achieve 40% renewables," GHD project lead Andre Tenorio told the committee during the briefing.

Committee Chair Jude Ntalanov Schneider opened the hearing by thanking the utility staff for keeping service running and framing the session as an informational exchange.

Key findings presented - Demand forecast: GHD presented low-, base- and high-case demand scenarios for each island. For Saipan, the presentation showed a high-case peak near 68…
