Developer rPlus and utility PacifiCorp have amended an existing PPA for a solar-plus-storage project, to increase the energy storage resource’s planned size from 400MWh to 1,600MWh.

Pacificorp has released its 2023 Integrated Resource Plan (IRP) outlining significant solar, wind and storage capacity expansions as well as investment into new transmission lines.

PacifiCorp has formalised a long-anticipated shift from coal to solar, wind and battery storage, setting ambitious targets underpinned by a belief in clean energy’s sound economics.
