Colo regulators to examine Xcel coal plan

Colorado state regulators this week will consider approving Xcel Energy’s $1.3 billion plan to stop burning coal at its electric power plants in Denver and Boulder.

Xcel Energy plans to shut down a coal fired generator at Boulder’s Valmont power plant by 2017 and replace four coal-fired generators with natural gas at Denver’s Cherokee power plant by 2022.

Under the plan submitted in August to the Public Utilities Commission and examined by The Boulder Daily Camera, Xcel also plans to shut down a coal-fired generator and convert another to natural gas at its Arapahoe plant in Denver and install emission controls at plants in Brush and Hayden.

The changes are prompted by the new Clean Air-Clean Jobs Act signed by Gov. Bill Ritter in April.
