A Keenesburg property carrying nearly half a century of energy history is changing course. The site, which has close to 50 years of energy heritage, is now being outfitted with 16,000 solar panels — a sharp departure from its origins as a coal operation active in the 1980s.
The installation is sized to generate about 7.2 megawatts and meet roughly 7% of the yearly electricity needs of Molson Coors' Golden Valley campus. The connection between a Weld County field and a Jefferson County brewing complex runs through the regional utility network. Rachel Schneider, Molson Coors' vice president of sustainability, explained that the output will enter the Xcel grid from which the Golden Valley campus draws power, covering approximately 7% of that campus's total annual electrical load.
The Golden Valley campus is more than a single brewery; it also includes a yeast drying facility, a can plant, a bottle plant, and a distribution operation. The energy offset therefore spans a wide range of manufacturing and logistics activity, meaning the solar farm's contribution reaches well beyond beer production alone.
State Rep. Carlos Barron, whose district covers Colorado House District 48, noted that Weld County has long served as a significant contributor to the state's overall energy output. Barron pointed to the county's varied portfolio — oil, natural gas, and now solar — and argued that adding to that mix works to the advantage of local municipalities throughout the county.
The conversion puts previously mined land back to productive energy use and adds another renewable source to Colorado's broader power supply. The shift from a resource-extraction model to electricity generation mirrors a pattern seen at other decommissioned fossil-fuel sites around the region.
Molson Coors indicated it controls additional acreage at the Keenesburg location that could accommodate further solar development, with Schneider saying there is ample room to expand the project.
No completion date for the current installation was included in available reports, and the scope and timing of any future solar phases at the site have yet to be announced.
