• PacifiCorp released a request for proposals on July 7 seeking 4.3 GW of renewable energy and battery storage, the largest RFP in the utility's history. While the RFP seeks resources for the near term—1,823 MW of solar, 595 MW of battery storage and 1,920 MW of wind operational by the end of 2024—longer-lead-time projects such as pumped storage may submit offers with later commercial operation dates. The RFP says a "reasonable on-line date" for a pumped-storage project is five years from signing a contract, or Dec. 31, 2026.
