The Environmental Justice Coalition (EJC), comprised of GRID Alternatives and Vote Solar and represented by GreenLatinos, has successfully advocated for major improvements to Xcel Energy's 2026-2027 Renewable Energy Plan, resulting in increased incentives and improved accessibility for income-qualified customers. 

On April 7, 2026 the Public Utilities Commission (PUC) of Colorado issued its written decision solidifying the January recommendation from the Administrative Law Judge who recommended that the PUC approve the settlement reached between the EJC, Xcel Colorado, and other stakeholders last November. 

A Renewable Energy Plan outlines how utilities will expand renewable energy capacity to meet the state's goal of 100% renewable energy by 2040. The plan includes incentive programs to encourage residential solar, community solar, battery storage, workforce development, and community engagement. Xcel Colorado submitted its plan to the PUC for approval to ensure transparency, regulatory oversight, and opportunities for stakeholder input.

“We’re pleased with the outcome of this proceeding, said Jamie Valdez, Colorado Transportation and Energy Advocate with GreenLatinos “The EJC worked hard to ensure GreenLatinos members and low-income households across Colorado will be able to enjoy the benefits of a just energy transition with reliable, affordable electricity,regardless of their socioeconomic status, and this decision by the PUC advances those goals.” 

“Through the settlement, the EJC secured a $1.5 million shift in program funding to strengthen equity participation,” said Jessica Herrera, counsel for the EJC. “This reallocation of funds advances the equity and access priorities established under Senate Bill 21-272 by increasing incentives levels and expanding access to solar and battery storage programs for income-qualified and disproportionately impacted communities.”

The EJC's intervention in the proceedings has led to several key provisions aimed at promoting equitable access to renewable energy:

- Increased Solar*Rewards Residential Incentive: The incentive for income-qualified/disproportionately impacted community customers has been raised to $3 per watt, up from the initially proposed $2 per watt.

- Enhanced Renewable Battery Connect Incentive: The incentive for income-qualified customers has been increased to $1,000 per kilowatt, up from $800 per kilowatt.

- Community Solar Capacity Roll-Over: More than 200 MW of capacity from the previous plan will be rolled over into the new Inclusive Community Solar program, and frontloaded to enhance developers' ability to secure the Investment Tax Credit.

- Spanish Language Accessibility: Key program webpages, the Solar*Rewards Income Qualification Verification Form, and associated marketing and educational materials will be provided in Spanish to better serve the one in ten Colorado households that speak Spanish.

- Outreach and Engagement Effectiveness Data Collection: Xcel Energy will collect data to assess the effectiveness of its outreach and engagement efforts in enrolling income-qualified and disproportionately impacted community members into its programs.

"Stakeholders involved in shaping the Renewable Energy Plan brought forward bold, community-centered ideas to ensure the benefits of clean and affordable energy, like solar, reach everyone,” says Claudine Custodio, Regulatory Director for Vote Solar. “We are proud to have reached a compromise that advances programs designed to lower energy bills and deliver meaningful, long-term savings for families struggling with rising utility costs."

These provisions are designed to ensure that the benefits of renewable energy are accessible to all customers, particularly those in low-income and disproportionately impacted communities. The EJC's advocacy underscores the importance of equitable participation in the clean energy transition.

“We’re grateful that all parties remain committed to distributing the benefits of renewable energy, particularly to income-qualified households and customers who have been struggling to realize those benefits,” says Daniel Pontón Aronoff, Interior West Policy Manager for GRID Alternatives, “The EJC worked hard to come to a Settlement Agreement that upholds that commitment, and we’re pleased that the Commission has recognized that effort.”
