Colorado Renewables Hit Majority Share in Q2 2026
Renewable sources provided 56.1% of Colorado's electricity in the second quarter of 2026, the first time they achieved a majority. Solar generation surpassed coal in the first half of the year, and all remaining coal plants are slated to close by 2031.
Colorado's Q2 2026 milestone marks the first time renewables have held a majority share of the state's electricity mix, with solar generation alone surpassing coal across the first half of the year. The state's remaining coal plants are now scheduled to close by 2031, capping a transition that has accelerated in recent years.
The Colorado result aligns with broader national momentum. U.S. solar installations rose 45% in Q2 2026 compared to the same period in 2025, reaching 11.4 GWdc, with utility-scale projects driving nearly all of that growth. The combination of state-level policy timelines and falling solar costs suggests similar majority-renewable milestones may emerge in other states before the decade ends.
Colorado's renewable majority could reshape electricity pricing and grid reliability for residents and businesses, as solar's variable output requires storage and transmission investments. Workers in coal-dependent communities may face economic disruption as plant closures approach by 2031. The milestone may also signal to other states that high renewable penetration is achievable, potentially influencing regional energy planning and utility investment decisions across the West.
