Project Benefits

Hesperus Solar Project is a solar energy project currently under development that will provide clean, low-cost energy, generate new jobs, and provide significant local tax contributions and environmental benefits for the surrounding community. Hesperus Solar has made commitments to provide the following benefits:

Preserving Rural Lands

Hesperus Solar will encompass approximately 1,900 acres of rural lands with low-impact solar installation, generating tax revenues through production for an estimated 30+ years. More than two-thirds of the site will remain under local ownership, and those landowners will receive lease payments during the project’s lifetime.  

Employment and Professional Development

Hesperus Solar will bring approximately 150 full-time equivalent construction jobs on average, with up to 250 jobs during peak construction periods to La Plata County. The project will generate opportunities for professional development including local recruitment, engineering teaching programs, and on-the-job training. Primergy projects focus on utilizing regional vendors to bolster the local economy.

Tax and Revenue Sharing

Hesperus Solar will provide tax payments, totaling up to $37 million, over the life of the project, which will directly benefit local schools and provide La Plata County with substantial resources that may be directed towards public safety, road upgrades, and infrastructure improvements.

Environment and Grid Resiliency

Hesperus Solar will generate 155 MWac of solar, which is enough clean reliable energy to power up to 56,000 homes annually.  The addition of a 155 MW battery energy storage system (BESS) will provide a consistent, dispatchable energy resource designed to support Colorado’s peak energy demands.


When will Hesperus be under construction and how long will it take to complete construction?

Hesperus is expected to begin construction in 2024. Project construction may be delayed or accelerated based on multiple factors including permitting, the availability of materials, and electricity offtake arrangements.

Once the project starts construction, it will take approximately 12-18 months to complete and begin delivering clean, low-cost solar energy.

Are solar projects safe?

Yes. Primergy Solar takes all measures to ensure safe operations. Electricity generated with solar panels emits no greenhouse gases and no air or water pollutants. An assessment of the full lifecycle of solar panels concludes they have 4% of total greenhouse gas emissions than a coal-fired plant.[1]

The project will be monitored 24 hours a day, 7 days a week from our remote operations desk. This ensures that we are aware of the operations at the site at all times.


How do I share information about land I own that might qualify for future solar projects?

Primergy Solar would be happy to hear from you! We typically are interested in properties 10 acres or larger as a typical solar energy facility requires 8 acres of land for every MW of solar energy generated. Ideal properties are located nearby electric lines and substations. Please contact to see if your property fits our needs.

How do I get in touch with Primergy Solar with questions, concerns or comments?

Primergy appreciates your questions and comments. Please email and we will get back to you!

How are solar projects safely monitored?  

Primergy Solar takes all measures to ensure safe operations. The Project will be overseen by a dedicated on-site operations and maintenance team, complemented by round-the-clock monitoring, to ensure awareness of ongoings at the site at all times.
