Craig Coal Mine Closes as Black Hollow Solar Opens

Steamboat Springs —The silence in the open pit of the Trapper Mine is louder than the machinery ever was. For 49 years, this hole in the ground next to the Craig Generating Station roared with the rhythm of extraction, a mechanical heartbeat that powered homes across the region. On September 25, the last scoop of coal was lifted from the earth, and with it, a specific kind of industrial noise vanished from the Western Slope. It’s a quiet that feels sudden, almost disorienting to those who grew up with the hum of combustion.

But if you look closely at the geography of this transition, the story isn’t one of loss; it’s one of displacement. About 250 miles to the east, in a place called Severance just outside Fort Collins, another kind of energy is waking up. The Steamboat Pilot reported that Platte River Power Authority celebrated the completion of Black Hollow Sun, a 257-megawatt solar project that will feed electricity to Longmont, Estes Park, Loveland, and Fort Collins. It is a massive shift in how we think about power flow: the West stops burning, and the East starts shining.

This counterintuitive pivot challenges the local narrative that renewable energy is a distant, abstract concept. It is happening now, in real time, reshaping the grid that serves our neighbors on the Front Range. The paper noted that Colorado has hit a tipping point, with more than 50% of the state’s electricity coming from renewables over the previous 12 months, according to Energy Information Administration data. This is not a projection; it is the current reality of the grid.

Platte River, which holds a minority interest in the Trapper Mine, is navigating this dual existence. Jason Frisbie, the CEO of Platte River, stated at the ribbon-cutting that he is confident the utility will achieve “well in excess of 80% non-carbon energy” by 2030. This goal aligns with a directive adopted in 2018 by directors representing the four member municipalities, who set their sights on 100% renewable electricity by that same date. The 544,740 solar panels at Black Hollow alone won’t cross that finish line, but they move the needle significantly.

The economics of this shift are often misunderstood locally. Some politicians have blamed renewables for rising rates, but the Steamboat Pilot pointed out that Holy Cross Energy achieved 90% renewables through August while maintaining some of Colorado’s lowest electricity rates. Cost has not been the barrier; reliability is. As coal units at Craig close before 2029, the challenge becomes how to keep the lights on when the sun sets or the wind dies. The U.S. Department of Energy recently announced two grants of $250 million each for projects connecting Colorado to the Eastern interconnection grid, a move designed to spread risk across larger markets.

There is a warmth to this transition that goes beyond the physics of electrons and photons. It’s the understanding that the energy powering your home in Craig may have been generated by a field of panels in Yuma County, or that the power keeping the lights on in Longmont is being harvested from the high plains. The grid is becoming a web, not a pipeline.

As the final coal units at Craig wind down, the landscape around the mine is beginning to settle. The dust is clearing. What remains is a scar in the earth, marking decades of extraction, now standing still while the sun moves across the sky above it.
