IEEFA U.S.: PacifiCorp’s transition to renewables and battery storage sets a new industry pace

Forward-looking template is one that lagging utilities like Duke Energy and Southern Company can follow

PacifiCorp’s announcement last week that it will build thousands of megawatts of new wind, solar and battery storage capacity in its transition away from coal will reshape electricity markets across the West over the next 10 years. Its impact will be felt nationally, too, perhaps nowhere as much as in the Southeast. The reason behind […]

IEEFA U.S.: Solar-plus-storage is undermining the economics of existing coal-fired generation

Utilities see potential in a money-saving shift

A harsh new reality is undermining the U.S. coal-fired electricity sector: Cleaner generation by way of utility-scale solar backed with storage is an increasingly cheaper option for utility companies than continuing to operate aging coal plants. The most recent—and perhaps most detailed—example of this new paradigm can be seen in ongoing long-term resource planning by […]
