Utility rules and programs for Post Falls

Avista and Kootenai Electric serve Kootenai County, so which rules apply depends on your address.

UtilityTypeSolar export rule
Avista Corpinvestor-ownedAvista offers a net metering option in Idaho (Schedule 63) in which kWh credits offset later use; a third-party summary says unused credits are forfeited each March 31. We could not read the current tariff, so confirm the cap and dates with Avista.
Kootenai Electric Cooperativemember-owned cooperativeKootenai Electric net meters members’ systems: the extra is banked as kWh and offsets later bills, but the co-op pays no cash for banked kWh. A $32.50 monthly availability charge applies to net meter locations, and a rate redesign in January 2026 changed net metering terms.

Program details are from each utility’s own pages (read October 2026). See the Idaho incentives table for statewide credits and a status for every program.
