Renewable Energy Purchase Program

Estes Park Offers a Renewable Energy Option

Did you know that you can choose to switch to 100% renewable energy at your home or business today? Through the Renewable Energy Purchase Program (REPP), customers can sign up to purchase 100% carbon-free renewable energy either in 100 kilowatt-hour blocks or to cover their entire electric consumption. When customers participate in the REPP, they are supporting an alternative to fossil fuels.

With every block purchased more renewable energy will be used to power the grid. Each renewable energy purchase helps build a market for renewable electricity. It also has other local and global environmental benefits, which may include emitting little or no regional air pollution or carbon dioxide. Please refer to the full Prices, Terms, and Conditions for more information.

Where does the REPP energy come from?

Renewable energy is purchased from Platte River Power Authority, Estes Park's wholesale electricity provider. Platte River acquires renewable energy from a variety of sources, including:

  • Silver Sage Wind Project, owned and operated by Duke Energy. Platte River has purchased a power agreement through 2029.
  • Medicine Bow (Wyoming) Wind Project, owned and operated by Medicine Bow Wind, LLC. Platte River has purchased a power agreement through 2033.
  • Spring Canyon Wind Energy Center (Colorado), owned by Clearway Energy and operated by Invenergy Wind LLC. Platte River has purchased a power agreement through 2039.

Other potential sources of renewable energy:

  • Short term purchases of renewable energy from other sources may be made when the supply of energy from the Silver Sage and Medicine Bow wind projects is not enough to cover demand.
  • Some renewable supply may be sourced as unbundled Renewable Energy Certificates from other regional wind generation.

Refer to the current Product Content Label to see the current mix of renewable energy sources. For comparison, the current average mix of resources supplying Estes Park non-renewable subscribers includes Coal (42.6%), Natural Gas (0.4%), Hydroelectric (19.1%), Solar (2.3%), and Unspecified Purchases (14.8%). This resource mix was provided to Estes Park by Platte River Power Authority for the year 2020.

Estes Park's Renewable Energy Purchase Program is Green-e Energy certified, and meets the environmental and consumer-protection standards set forth by the non-profit Center for Resource Solutions. Learn more about the Green-e certification at and about how renewable energy purchases work in the video below.


How much does the REPP cost?

For residential customers, REPP energy is sold in 100 kilowatt-hour (kWh) blocks, the cost is added to your regular utility bill. The cost per block is $2.75 (as of January 2021). You can buy as many REPP blocks as you need for your specific energy requirement. The average home in the United States uses 914 kWh per month. [Source: US EIA, 2020] Your bill will increase according to the number of REPP blocks you purchase.

For commercial customers, there is a 500 kWh per month minimum required.
