Solar & batteries with Southeast Colorado Power Association

SECPA lets you pick when your bank settles. A true-up after the October bill clears the summer’s surplus before winter; one after February gives winter usage time to draw the bank down first. For most homes sized to annual use, February leaves less to sell back at wholesale — but look at your own monthly pattern.

Leftover kWh are credited at Tri-State’s wholesale energy rate, well below the $0.13005/kWh retail energy charge. That’s the case for sizing to use, not to the 10 kW cap.

At about 13¢/kWh plus a $31.25 access charge, SECPA’s farm-and-home rate is higher than several neighboring co-ops, and the Arkansas Valley and southeast plains get strong, reliable sun. Solar you use yourself goes further here than in lower-rate territories.

SECPA requires $300,000 of liability insurance for systems 10 kW and under. Participation is limited under Tri-State’s all-requirements contract, so we confirm capacity with SECPA before you commit.

SECPA's Schedule NM (revised May 1, 2026) net-meters 10 kW residential and 25 kW non-residential systems under any rate schedule — irrigation included — first-come, first-served, with no provision for larger systems and a cap tied to the customer generation its Tri-State supply contract allows. Monthly excess banks 1:1; each year the remaining kWh are credited at Tri-State's wholesale energy-only rate, at a February or October true-up the member elects. Net-metered businesses still pay every demand charge of their underlying rate: General Service–Demand $8.35/kW on-peak (also used for grain storage), Large Power $16.67/kW, and irrigation-demand $10.16–$15.16/kW. No solar rebate.

Demand charges are the part of a commercial bill panels alone don't reliably cut, which is why our commercial proposals in SECPA territory usually model a peak-shaving battery alongside the array. County-by-county detail is on our commercial pages.
