CORE’s 25 kW commercial net-metering limit
Above 25 kW, commercial systems are interconnected as qualifying facilities under CORE’s tiered process, and exports aren’t net-metered one-for-one. That makes daytime load the anchor for sizing. Retail and medical buildings with steady daytime use are good fits; buildings empty at midday are harder.
Confirm how CORE will credit exports for your specific system size before committing.
Xcel-served businesses in Lone Tree
Lone Tree’s office and retail buildings are mostly on Xcel commercial rates, with demand charges that solar alone may not cut reliably. Storage programmed for peak shaving often moves the bill more.
Timing and paperwork
Unincorporated commercial projects need structural and electrical engineering stamps for PV. As of September 2026, commercial solar generally must be placed in service by December 31, 2027 for §48E unless construction began by July 4, 2026. Plan with your CPA.
FAQ
Questions we hear
What’s CORE’s net-metering limit for businesses?
25 kW. Larger systems interconnect as qualifying facilities with export credits CORE sets.
Does Douglas County require engineer stamps for commercial solar?
Yes. For systems other than dwellings, the county requires an electrical engineer’s and a structural engineer’s signature and seal.
Our Lone Tree office is on Xcel. Will solar cut demand charges?
Sometimes, but not reliably on its own. Pairing solar with storage for peak shaving usually does more.
Is there still federal value for commercial solar here?
As of September 2026, yes, for solar placed in service by the end of 2027 or begun by July 4, 2026. Confirm with your tax advisor.
