As coal plants close, more calls for 100% renewable goals
DURANGO, Colo. – The Sierra Club has been pushing Durango to commit to 100 percent locally produced and renewable electricity by 2050.
The argument of petitioners, reports the Durango Herald, is that in addition to cutting carbon emissions, the local, renewable energy would create local jobs and stabilize energy rates as the cost of fossil fuels continues to rise.
The petition in Durango fits in with a broad pattern across the country of calls for municipalities to embrace goals of 100 percent renewables during the next few decades. In Utah, for example, Salt Lake City, Moab, and Park City have all embraced that goal. In Colorado, so have the Front Range communities of Fort Collins, Boulder, and Pueblo.
That goal no longer seems so far-fetched. Major, investor-owned utilities have been rapidly investing in renewables not because they have to, but because of tumbling prices for wind, but also solar. Cost of utility-scale storage has also started sliding.
Last week, Colorado’s largest utility, Public Service Co., a subsidiary of Xcel Energy, announced that it would seek approval of state regulators to retire two coal-fired generating plants at Pueblo, which began operations in 1972 and 1974. The retirements, if approved by the Colorado Public Utilities Commission, will mean Comanche I and II will be retired a decade earlier than previously scheduled.
Xcel wants to replace the lost power with some natural gas-fired electricity but mostly with renewables, with up to 1,000 megawatts of wind and 700 megawatts of solar. It wants to move fast, too, to take advantage of federal tax credits that are scheduled to expire in 2020.
Cost to consumers will stay the same or more likely go down, explained David Eves, the utility’s president of Colorado operations. Reduced greenhouse gas emissions are a bonus.
After the switch, Xcel expects its will be at 55 percent in carbon-free generation. This year, it will be completing conversion of a coal-fired power plant in Denver to natural gas. It had also converted a plant in Boulder last year.
Xcel delivers power to Colorado’s Summit County, where Breckenridge elected officials recently heard from a local group that wanted a commitment to 100 percent renewables, first in city operations and then a few years later in the community at large. Town officials weren’t ready to commit, lacking a clear path to achieve these goals. This was a week before the Xcel announcement.
Mark Truckey, a town planner in Breckenridge who is a member of the local 100 percent group, called the Xcel announcement “huge.”
“This has to speak volumes about how the cost is coming down,” he said. Yet he concedes it’s not exactly clear how Breckenridge can achieve what his group advocates.
In Utah, it’s the same story. Rocky Mountain Power last week reached a deal with solar advocates about a transition. The utility, which serves Park City, has a plan for adding more wind generation from southern Wyoming and upwards of 1,000 megawatts —the equivalent of a giant coal-fired power plant—in solar generation from Utah.
