Black Mesa Energy and Idaho Power have taken their three-year contract dispute back to the Idaho PUC, saying that settlement talks stalled. The latest chapter began in March, when the energy developer—which is seeking to build solar projects combined with battery storage—asked the commission to determine it had established legally enforceable obligations with the utility for two proposed QF developments, Black Mesa Energy 1 and 2. In July, the developer and the utility entered into talks to resolve the dispute. However, on Nov. 13, the two parties told the commission they couldn't resolve their dispute.

The Montana PSC has approved a utility resource plan that includes retiring coal-fired resources. In late October, the commission signed off on Montana-Dakota Utilities' 20-year integrated resource plan, which includes closing the 44 MW Lewis and Clark coal plant in March. The utility's plan also includes closing two units at Heskett coal plant in North Dakota.
