Valley Range solar project seeks county approval
Estimated reading time: 5 minutes · Last updated:
Accelergen Energy LLC will ask Montezuma County this fall to approve Valley Range Energy Park, a 125-megawatt solar project paired with 62.5 megawatts of battery storage located east of Cortez along U.S. 160. As first reported by the Durango Herald, Accelergen development director Matt Ryan said the company will submit a special-use permit application this week; the county’s Planning and Zoning Commission is set to review the application on Oct. 8, and the Board of County Commissioners is likely to decide in November. The proposal places roughly 900 acres of panels inside about 2,100 leased acres and includes land set aside for conservation.
“We want people to understand that we’re not here to push things through a permit and throw a bunch of panels out in the field. It’s really about making sure people understand their feedback matters,” Ryan said.

Key takeaways
- Project size: The Valley Range Energy Park proposes 125 megawatts of solar generation and 62.5 megawatts of battery storage.
- Land area: Solar arrays are designed to cover roughly 900 acres within approximately 2,100 acres Accelergen has leased.
- Construction and jobs: Ryan said Accelergen expects a 2027–28 construction phase that would create an estimated 95 new jobs and $7.8 million in local spending.
- Safety and technology: Accelergen plans to use lithium-iron-phosphate batteries, 24-hour monitoring and automatic safety shutdown features for the storage system.

What the Valley Range project would deliver
The Valley Range Energy Park is described by Accelergen as a combined solar and storage installation that pairs 125 megawatts of photovoltaic capacity with a 62.5-megawatt battery system. Accelergen’s plans would place roughly 900 acres of solar panels inside a larger leasehold of about 2,100 acres; the company says some leased land will remain undeveloped for setbacks, wildlife corridors and conservation. The battery-storage footprint is expected to occupy between 4 to 8 acres on site.
Accelergen’s development director, Matt Ryan, told local officials the storage chemistry will be lithium-iron-phosphate rather than older cobalt-based chemistries and that the system will include 24-hour monitoring and automatic safety shutdown features. The developer says those design choices respond directly to national concerns over large-battery fires and to local questions about site safety.
Permitting timetable and commercial steps
Accelergen will file a special-use permit with Montezuma County, and Ryan said the company expects the county Planning and Zoning Commission to review the application on 8 October, with the Board of County Commissioners likely to take a final vote in November. Ryan said Accelergen will seek permit approval before finalising agreements with either local utilities or regional transmission operators, and that the company sometimes places equipment deposits that can exceed $10 million after those agreements are secured.
Those sequencing choices matter because project finance and equipment procurement typically depend on an executed interconnection or power purchase contract. Ryan told reporters the developer is in late-stage conversations with local utilities but will avoid placing large deposits until it has the permit in hand.
Local economics, land use and community responses
Accelergen has supplied a financial forecast estimating roughly $13.9 million in local property taxes over the project’s 35-year life, which the company presents as an average of about $398,000 per year for Montezuma County. The developer also projects 95 jobs during the construction window and $7.8 million in direct and indirect local spending during the anticipated 2027–28 build period.
Montezuma County continues to weigh land-use issues following the six-month pause on approving new solar projects that ended in November 2025. Montezuma County adopted new land-use codes at the end of that pause that favour projects supporting agriculture, limiting visual impacts and requiring proper decommissioning. Emily King Kinsey, a project representative, said Accelergen set aside more land for conservation and setbacks to address visibility and wildlife concerns.
Safety, technology choices and agency coordination
Developers and county officials have focused outreach on fire response and wildlife protection. Ryan said Accelergen consulted the Cortez Fire Department on emergency-action response plans and worked with Colorado Parks and Wildlife on migration corridors. The developer also said it has engaged Colorado State University Extension Offices and Dolores-based Southwest Seed corporation on a land regeneration project for disturbed areas.
On battery safety, Accelergen pointed to its choice of lithium-iron-phosphate batteries and continuous telemetry for battery-behaviour management. Those measures are presented as mitigations for national concerns raised after fires at older facilities, including at Moss Landing, and will be part of the permit and emergency planning the company submits to county reviewers.

How the project could advance — and what could stop it
The case for
- Permit approval at the county level would allow Accelergen to finalise utility contracts, place equipment deposits and move into the anticipated 2027–28 construction window.
- Set-asides for conservation, explicit decommissioning plans and consultations with the Cortez Fire Department and Colorado Parks and Wildlife could reduce opposition and speed local approvals.
The case against
- Visible impacts and neighbour opposition, revived during public hearings, could delay permit approval or force design changes that raise costs.
- Failure to secure interconnection agreements or to reach utility contracts after permitting would leave the project unable to book equipment deposits and could stall the timeline despite a county permit.
What to be careful about
- Local opposition focused on visual impacts and previous moratorium politics could produce contested hearings or appeals after the Oct. 8 Planning and Zoning review.
- Battery-safety concerns remain a material exposure for permitting and emergency planning despite Accelergen’s stated choice of lithium-iron-phosphate chemistry and 24-hour monitoring.
- Project economics depend on later-stage utility contracts and deposits; Ryan said Accelergen will not place large deposits until it has permit approval, so contracting risk could halt the project after permitting.
The bottom line
Valley Range Energy Park bundles a sizeable solar array with utility-scale battery storage and a slate of local benefits that Accelergen says will include property-tax revenue, temporary construction jobs and local spending. The developer has framed technical choices—lithium-iron-phosphate chemistry, 24-hour monitoring and emergency plans—as direct responses to community safety concerns. The project’s near-term fate rests on Montezuma County’s fall reviews and, after permitting, on successful utility contracting; both steps will dictate whether the anticipated 2027–28 construction window can begin.
What to watch
- Oct. 8, 2026: Montezuma County Planning and Zoning Commission review of Accelergen’s special-use permit application.
- November 2026: likely Board of County Commissioners decision on issuing the special-use permit.
- 2027: start of the construction window if permits and utility contracts are finalised for the anticipated 2027–28 build phase.
Frequently asked questions
What is the size and storage capacity of the Valley Range project?
The proposal calls for 125 megawatts of solar generation and a 62.5-megawatt battery system, with roughly 900 acres of panels inside about 2,100 leased acres.
Who is developing the project and what is their background?
Accelergen Energy LLC, an Austin-based startup founded by Josh Skogen and Thomas Houle, is the developer; the founders previously built sPower, which later merged with AES.
