Utilities in Colorado are planning to add a lot more renewable energy over the next few years, for a variety of reasons. I’ve looked at a couple of the trends driving this energy transition such as 100% renewable energy commitments from the utilities’ major customers, including towns and cities like Pueblo and Boulder, and major companies like Aspen Skiing Company, Google, Vail Resorts, IBM, Anheuser-Busch, and New Belgium.
But perhaps the biggest reason that utilities in the region are pursuing more renewable energy is that the low costs of wind and solar energy have continued to fall, opening up a huge market: replacement power for existing coal plants.
Cheap renewable energy has already meant that when utilities needed new power generation in recent years, they have mostly chosen renewable energy. Nationwide, wind and solar power represented about two-thirds of all the new electricity generation capacity that was brought online in both 2015 and 2016, according to the US Energy Information Agency.
But as the costs of building new wind and solar projects have kept dropping, renewable energy is now becoming cheaper even than continuing to run existing coal-fired power plants - as Colorado Governor John Hickenlooper recently noted, “Coal is no longer the low-cost fuel."

The town of Breckenridge passed a resolution last week establishing a goal to power the community with 100% renewable electricity by 2035. Breckenridge joins other Colorado towns and cities that are pursuing 100% renewable energy, including Pueblo, Boulder, and Nederland. Aspen achieved its 100% renewable energy goal in 2015, while other towns and cities including Denver and Durango are also considering renewable energy goals.
The responses from the utilities that serve those Colorado towns and cities show that these 100% renewable energy goals are helping push the region toward a cleaner electricity grid, achieving a broader impact than sustainability goals that remain within the boundaries of a municipality. That’s consistent with a new report by global management consulting firm McKinsey & Company, which argues that cities should focus their sustainability efforts on four strategic areas for maximum impact. First among those four strategic areas is using their position as major electricity consumers to help decarbonize the electricity grid:
While cities may believe they have little influence over the grid mix, in fact, they often represent a major portion of any local electric utility’s customers, potentially giving them significant leverage to shape the emissions profile of the electricity consumed within their metropolitan area. Still, capturing this opportunity will not be easy, and cities cannot do it alone. Utilities and regulators must play a central role in ensuring the overall mix of renewables is appropriately balanced at a system level and that critical components such as energy storage are in place to ensure grid reliability. Nevertheless, cities have an essential role to play by setting clear decarbonization goals, aggregating demand for renewables, promoting energy efficiency, and shifting more urban energy consumption to electricity (especially in transportation and heating).
Lowering the emissions intensity of the electricity grid is an especially impactful way that municipalities in the Rocky Mountain region can advance their sustainability goals, because the region’s grid is more dependent on coal, and therefore more carbon intensive, than other parts of the US. But as these Colorado towns and cities seek to accelerate the transition to renewable energy, they face varying challenges in working with the different utilities and electric cooperatives that sell electricity in Colorado. Colorado towns and cities are served by two investor owned utilities, 29 municipal utilities, and 22 rural electric cooperatives, according to the Colorado Energy Office
Let’s look at four Colorado municipalities pursuing renewable energy goals, each with a different electricity provider: Breckenridge, Pueblo, Aspen, and Durango.
