Arizona regulators have repealed the renewable energy standard for electric utilities in the state, saying it's time for renewables to "stand on their own two feet."

Two Arizona utilities received approval to convert coal-fired power plants to run on natural gas, projects they say will enhance grid reliability, reduce emissions and preserve jobs.

Arizona Public Service would save $110 million/year by joining CAISO's Extended Day-Ahead Market rather than SPP's Markets+, a new analysis found.

Colorado lawmakers have introduced a bill that would impose renewable energy requirements on data center developers and ban shifting of cost for electricity and grid investments to other utility customers.

SPP has hired former Idaho commissioner Kristine Raper as its senior director of state regulatory policy for the West.

Public Service Company of Colorado and the Polis administration want to keep Unit 2 of the coal-fired Comanche Generating Station running a year longer than planned.

With data centers contributing to surging load growth, a new report suggests that more Western utilities should adopt clean transition tariffs or even make the tariffs mandatory for certain large customers.
