Colorado Hits 53% Renewable Energy Milestone Despite High Grid Costs

Fifty-three percent. That’s the share of Colorado’s electricity generated by renewable sources in the first three months of this year. It’s a number that sounds like a policy victory lap, but let’s be clear: it’s also a statistical artifact that obscures the gritty, expensive reality of keeping the lights on for folks who don’t live in the shadow of a massive hydro dam or a sprawling solar farm.

The Vail Daily reported that this milestone, driven by falling wind and solar prices, puts the state on track to end the year above 50%. But if you look at the map, the picture gets complicated fast. Colorado isn’t leading the pack. As of 2024, we ranked only 12th in the percentage of electricity from renewables. South Dakota, with its heavy reliance on hydroelectricity from the Colorado River dams, sits at 80%. Iowa, once coal-heavy, is now pulling 70% from wind.

We’re not winning. We’re just catching up to states that have been playing a different game for decades.

The narrative pushed by officials is that the market has spoken: wind, solar, and batteries are the cheapest options. Chris Hansen, CEO of Durango-based La Plata Electric, told the paper that despite the Trump administration’s efforts to slow the fossil-to-renewable transition, the economics haven’t budged. “Wind, solar and batteries are still the cheapest options in the marketplace,” Hansen said.

That’s true on paper. It’s also true that solar prices have slid by up to 90% since 2010. Lithium-ion batteries are following a similar downward curve, allowing utilities to meet peak demands without firing up old coal plants. But “cheapest” doesn’t mean “easiest” or “uniform.”

Take Holy Cross Energy. Last year, 85% of the electricity delivered to members in Vail, Snowmass Village, and surrounding areas came from renewable sources. Why? Because they’re nimble, they have access to lower-cost transmission lines bringing power from eastern Colorado, and crucially, their demand has been relatively flat. They aren’t dealing with the erratic, skyrocketing consumption of the Front Range.

Hansen, who leads a cooperative with similar goals to Holy Cross, noted that he celebrates their success but has to solve the puzzle differently for La Plata. The geography is different. The infrastructure is different. The cost structure is different.

Ron Sinton, founder of Sinton Instruments in Boulder, argues that we need to stop treating Colorado’s 50% milestone as a finish line. “Colorado’s reaching 50% renewable energy is more important than any city or small utility in isolation,” Sinton said. But he warns against letting “perfect” electricity imperil broader decarbonization. Existing technologies can achieve maybe 90% emissions-free electricity without driving up costs. The other 10%? That’s the expensive part. That’s the part that requires storage, new transmission lines, and likely higher rates for locals.

The state has 22 electrical cooperatives and 29 municipal utilities to manage alongside Xcel Energy and Black Hills Energy. They aren’t all moving at the same speed. Xcel fought Amendment 37, the 2004 mandate that forced them to get 10% of their electricity from renewables by 2015. They grumbled. They complied. The prices dropped. Now they’re sitting at a comfortable majority.

But for the rest of us, the transition isn’t just about flipping a switch to wind or solar. It’s about paying for the grid stability that keeps the renewable energy flowing when the sun sets or the wind dies down. It’s about transmission lines that stretch across counties we’ll never visit. It’s about the fact that while 53% of our power is clean, the remaining 47% still needs to be reliable, dispatchable, and, increasingly, expensive.

The milestone is real. The progress is undeniable. But don’t expect your electric bill to drop just because the state hit a number. The cost of the transition is still being baked into the infrastructure, and the people footing the bill are the ones who need the lights to stay on, regardless of whether the wind is blowing.
