Colorado Approves Resource Plan with Potential for 1,450 Megawatts of Renewable Energy

September 22, 2008

The Colorado Public Utilities Commission has issued a decision approving an Xcel Energy resource plan to supply power through 2015. That plan includes the potential to add up to 600 megawatts (MW) of renewable energy resources with storage capability, such as concentrating solar power, and 850 MW of intermittent renewable energy resources, such as wind.

The plan also promotes energy savings, advances Colorado toward the state’s carbon reduction goals, ensures an adequate supply of resources in the future, and aims to keep consumers’ energy costs low. The 132-page decision concludes months of testimony, public participation, and review.

The decision:

  • Calls for demand-side management programs that will save at least 1,744 million kilowatt-hours (kWh) and reduce demand by 421 MW.
  • Adds a minimum of 200 MW and a maximum of up to 600 MW of developmental renewable energy resources with storage capability, such as concentrating solar power.
  • Approves an additional 850 MW of established intermittent renewable energy resources, such as wind energy.
  • Approves the closure of two older coal-fired plants to reduce carbon dioxide emissions, citing substantial health and environmental benefits.
  • Affirms that competitive bidding be used to acquire new generation, but allows the commission to examine the benefits of portfolios containing a range of utility ownership options.
