Utility rules and programs for Columbia
Columbia Water and Light, Boone Electric Cooperative and Union Electric serve Boone County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| City of Columbia | city-owned | Columbia Water and Light offers net metering under the state act and requires a signed Interconnection and Net Metering Agreement before you install; we could not read its current terms because its site blocked us. |
| Boone Electric Coop | member-owned cooperative | Missouri’s net metering law (RSMo 386.890) covers rural electric cooperatives, but each co-op’s board sets its own interconnection contract and the credit for exported power; we could not read Boone Electric Cooperative’s own policy, so ask for it in writing. |
| Union Electric Co | investor-owned | Ameren Missouri must offer net metering under RSMo 386.890 (systems up to 100 kW, leftover credited at avoided fuel cost, unused credit expires after 12 months). A search excerpt of an Ameren page lists 3.84 cents per kWh in summer and 3.39 cents in winter; Ameren’s site blocked us, so confirm the current rate with Ameren. |
Program details are from each utility’s own pages (read October 2026). See the Missouri incentives table for statewide credits and a status for every program.

Solar Panel Installation in Columbia FAQs
Is solar worth it in Columbia?
The sun is strong (about 1,240 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Missouri incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Missouri has no state solar tax credit that we found; installers buy equipment sales-tax-free under a Department of Revenue rule, but homeowners buying parts themselves do not.
Do I need a permit for solar panels in Columbia?
Usually yes, and the utility may need to approve solar and batteries. Building and Site Development handles permits in Columbia; see the permit information above.
