Delta County’s utility map

The largest by area, Delta-Montrose Electric Association, is a electric cooperative that sets its own export rules, which we confirm directly before designing.
Delta County by the numbers
Delta County grew about 3.1% between 2020 and 2025 (31,203 → 32,178). It has 6 communities on our map, the largest being Delta, Orchard City, Cedaredge.
Terrain varies: Delta sits near 4,920 feet while the county’s geographic center is around 6,180 feet, so snow load, shading and access can differ a lot from one address to the next.
It’s part of our Western Slope region. The county center is about 165 miles from our Denver office.
Who issues solar permits in Delta County
We pull permits wherever your address falls in Delta County — town building departments inside municipal limits, the county elsewhere, and the State Electrical Board for electrical permits where it has authority.
Solar for businesses in Delta County
Delta County businesses are split between Delta-Montrose Electric Association and City of Delta (municipal electric) — a electric cooperative and a town-owned utility — with different commercial net-metering terms, so two shops a few miles apart can have different paybacks.
The Western Slope's commercial roofs range from Grand Junction warehouses and dealerships to Palisade packing sheds, Delta and Montrose ag and equipment businesses, and self-storage along US-50 and I-70. Long, hot summers make cooling the dominant daytime load — a good match for solar production. Demand charges, roof structure and who pays the bill decide the project more than panel count does. As of September 2026, business owners can still use the federal §48E credit for solar placed in service by the end of 2027, with 100% bonus depreciation restored — details are on our Delta County commercial page and worth a conversation with your tax advisor.
