Weld County Approves $1.7B Chalk Bluffs Wind and Solar Project

Weld County commissioners voted 3-2 Wednesday to approve a $1.67 billion wind and solar facility near the Chalk Bluffs escarpment, the Colorado Sun reports, clearing the way for construction on 25,000 acres of active ranchland spanning Colorado and Wyoming.

Market Impact

The Chalk Bluffs project, developed by Enyo Energy, will place 2,200 acres of solar panels and 79 wind turbines across land stretching from U.S. Highway 85 to Colorado State Highway 390, crossing from Weld County into southern Laramie County, Wyoming. The facility is designed to generate 805 megawatts, enough to power 600,000 homes, with construction slated to begin in 2027 and wrap up by 2029.

Enyo Energy says it has secured 97% of the project area through long-term private land leases, with the remaining 3% covering state, federal or municipal land and easements. The company has pointed to a $47 million property tax payout projected over the project’s 30-year life and touted a boost in construction jobs during the three-year build. Commissioners Kevin Ross, Lynette Peppler and Perry Buck voted to approve the project, while commission chair Scott James and chair pro-tem Jason Maxey voted against it, following hours of public comment that included both ranching families in support and neighboring landowners opposed on grounds of habitat loss, topsoil damage and cultural significance to the Eastern Shoshone tribe.

What It Means for Subcontractors

• Civil and earthwork crews should expect a three-year construction window (2027-2029) across a 25,000-acre footprint, but no EPC contractor or subcontract packages have been named yet, confirm procurement stage before committing bid resources.
• Foundation and electrical trades tied to the 79 wind turbines and 2,200 acres of solar arrays should track interconnection and site design details as Enyo Energy finalizes engineering, since specifics on substation work and grid tie-in were not disclosed at approval.
• Heavy equipment operators working near the Chalk Bluffs escarpment should plan for topsoil protection measures given landowner testimony that regional topsoil “doesn’t recover quickly” once disturbed, a factor that may shape grading and restoration scope in future bid specs.
• Local labor and trucking contractors in Weld County and southern Laramie County, Wyoming, should watch for hiring announcements tied to the construction-phase job boost Enyo Energy cited, though no specific job counts or wage figures were provided.
• Subs bidding cross-border work should confirm whether Colorado and Wyoming permitting or labor requirements differ, since the project footprint extends into Laramie County under a separate state jurisdiction.
