Colorado State Solar Overview

Colorado, with over 300 sunny days per year, has tremendous solar potential and was one of the first states in the U.S. to adopt a Renewable Energy Standard. The state has since moved toward broader clean energy targets and continues to expand rooftop, community, and utility scale solar. SEIA is actively engaged in legislative and regulatory advocacy to support continued solar and storage growth and deployment.

 

SEIA Colorado State Policy Priorities

  • SEIA and the Colorado Solar and Storage Association (COSSA) collaborate closely to expand solar access and increase solar penetration in Colorado.
  • SEIA has consistently advocated for solar and storage in Colorado through testimony in the Colorado Renewable Energy Standard plan, electric resource planning processes, stakeholder discussions with Xcel Energy, and additional commission filings.
  • SEIA, COSSA, and coalition partners helped pass SB 218 and SB 207 in 2024, which modernized the distribution system to facilitate solar and storage interconnection and expanded access to community solar. Current efforts are focused on implementation and ensuring these reforms translate into increased deployment.
  • During the 2026 session, SEIA helped pass a slate of legislation that improves the interconnection process for projects and will help projects qualify for federal tax credits. These bills include:
    • HB26-1007: Expands consumer access to portable-scale solar generation devices (plug in solar) and requires all utilities to allow meter collar adapters for DERs.
    • HB26-1225: Ensures community solar bill credits will keep pace with utility rate trends, sets pathway for 3rd party interconnection studies and upgrades, introduces flexibility in dispatchable distributed generation program to allow stand-alone storage.
    • HB26-1268: Allows a local government to designate areas within its jurisdiction as renewable energy investment areas for the siting of renewable energy and energy storage system projects. (primarily a brownfields incentive bill)
    • HB26-1326: Reauthorizes Colorado Public Utilities Commission through 9/1/2033. Requires utilities to provide information to project developers to claim ITC for qualified interconnection property, ensures continuation of requirement of DG equal to or greater than 3% of retail sales, directs PUC to evaluate opportunities to streamline procurement/RFP processes.
    • HB26-1289: Extends state residential storage tax credit through end of 2029.
