Renewable Energy Standard

In 2004, Colorado passed the first voter-led Renewable Energy Standard (RES) in the nation, requiring electricity providers to obtain a minimum percentage of their power from renewable energy sources. The legislature has increased the amount of renewable energy required three times since 2004, including HB10-1001 which required investor-owned utilities to generate 30% of their electricity from renewable energy by 2020, of which 3% must come from distributed energy resources. The most recent update, SB 13-252, requires cooperative utilities to generate 20% of their electricity from renewables. Colorado was ranked eighth in the nation for installed solar capacity, with 398 MW of solar energy installed as of 2014. Colorado is home to more than 380 solar companies employing over 4,000 people throughout the state.
