Colorado Clean Energy Plan

Advancing the state's clean energy future

The Colorado Public Utilities Commission approved our Phase I Colorado Clean Energy Plan (external link) in 2022. As one of the nation’s leading clean energy plans, it will:

  • Reduce carbon emissions 80% to 85% (compared to 2005 levels).
  • Add unprecedented amounts of renewable energy to the grid.
  • End our use of coal by 2030.
  • Drive investment and economic development across the state.
  • Provide a just transition for communities with retiring coal plants.

To help deliver on our Clean Energy Plan, we launched a competitive bid process (PDF) in late 2022 soliciting new generation resources and received more than 1,000 energy project proposals from developers. After working with a third-party independent evaluator to validate findings and review bids, we submitted several project portfolios to the Commission for consideration in September 2023, in what is known as the “120-Day Report.”

In January 2024, the Commission approved Phase II of our Clean Energy Plan (PDF). The approved portfolio will add approximately 6,100 megawatts of new generation, making it the largest clean energy portfolio in state history by significantly increasing the amount of renewable energy on our system, and will also invest $12 to $13 billion across Colorado. Implementing this plan is an important step towards achieving a carbon-free future and brings forward new projects that will help achieve our carbon emission reduction.

Energy Saving Tip

Make sure to regularly change the air filters on your HVAC system (at least once per month). Old, clogged filters are far less efficient than new ones.

Break Ground, Not the Law

Always call 811 before digging in your yard to avoid hitting buried gas or electric lines. Not only is it the safe thing to do, but it's the law.
