Coal being pushed out of power market, PacifiCorp study acknowledges

摘要

After months of environmental groups’ claims that PacifiCorp was hiding the true economic picture of its coal-fired generation, the company presented an updated analysis showing that its customers could save money if four units at the Naughton and Jim Bridger plants in Wyoming are retired early, the utility said in a Thursday public presentation. The Berkshire Hathaway Energy subsidiary did not conclude what the least-cost way to retire those units and other coal facilities would be, because the utility must complete additional resource portfolio studies before submitting its final 2019 Integrated Resource Plan to regulators in the states it serves by August 1. The analysis also considered the possible retirement of five more units at three other coal plants, indicating lower potential savings for those.
