Avista Corporation (Avista Utilities)

Avista does not publish a dedicated residential EV time-of-use rate. A general residential time-of-use pilot under Washington rate schedules 07 and 08 opened in June 2024 but closed to new enrollment on May 31, 2025, so most residential customers in eastern Washington and northern Idaho pay Avista's standard residential rate and charge an EV at that flat price. Avista's only EV-specific rate is Schedule 13, a Washington commercial EV charging rate for non-residential customers with separately metered charging equipment, designed to lower demand charges by shifting load to off-peak hours.

Avista's standing EV incentives are weighted toward businesses, not homeowners. For Washington commercial and multifamily sites, Avista pays make-ready installation costs up to the charger and offers a utility-owned charger option, with per-port cost coverage of up to $5,000; there is no current standing residential charger rebate. The home-side offer today is Smart Charging, a managed-charging program that schedules charging to off-peak hours, with program terms running through March 31, 2027 subject to funding; it works best paired with a time-varying rate and a connected vehicle.

Avista's footprint changes which programs apply. The utility runs electric service in eastern Washington and northern Idaho but serves Montana only with natural gas, so its electric EV programs are Washington and Idaho only. Washington programs run under the Washington Utilities and Transportation Commission, and several incentives, including Schedule 13 and the commercial charging program, are explicitly Washington-only; Idaho customers, regulated by the Idaho Public Utilities Commission, see a narrower set of EV offerings.
