US power company PacifiCorp this week announced it has filed the final shortlist as part of its all-source request for proposals (RfP), saying that the bids represent close to 3,250 MW of renewable energy resources.
The Warren Buffett-owned utility kicked off the RfP a year ago in line with its 2019 Integrated Resource Plan (IRP). It said at the time that the 2019 IRP preferred portfolio includes 1,823 MW of solar co-located with 595 MW of energy storage, and 1,920 MW of wind farms, all secured by the end of 2023.
The company said it submitted the list to state regulators in Oregon on June 15. While it noted that the details of the bids are confidential, PacifiCorp unveiled that among the selected projects are: 1,641 MW of wind in Wyoming; 151 MW of wind in Idaho; 210 MW of solar in Oregon, including 52.5 MW of installed batteries; 1,243 MW of solar in Utah, including 682 MW of installed energy storage and one 200-MW standalone battery; and a new 400-mile, 500-kV transmission line from eastern Wyoming to central Utah.
“The battery resources complement the addition of more renewable energy by providing the flexibility needed to smooth imbalances between supply and demand. We are excited to add significant storage resources to our system,” said Rick Link, PacifiCorp vice president of resource planning and acquisitions.
