Idaho Power Co

Idaho Power's optional residential Time-of-Use plan, Schedule 5, separates energy costs into on-peak and off-peak periods. During summer (June through September), on-peak hours run from 3 p.m. to 11 p.m. Monday through Saturday; all other hours including nights and all day Sunday are off-peak. The summer off-peak rate is substantially lower than the on-peak rate, so owners who can shift EV charging to overnight hours pay less than they would on the standard residential rate. A new TOU Trial option launched January 1, 2026 lets customers test the plan for a full year; if charges would have been lower under the standard rate, the extra cost is capped at $10 for that year.

Idaho Power's verified EV incentive program is aimed at businesses and municipalities, not individual homeowners. Under the EVSE Incentive Offering, eligible commercial customers can receive 50 percent of project costs up to $7,500 per site for Level 1 or Level 2 passenger vehicle charging, with a cap of $15,000 per customer. Larger infrastructure including DC fast chargers and fleet electrification equipment may qualify for up to $20,000 per site. No residential EVSE rebate has been confirmed from Idaho Power's own rebates page; residential customers should check idahopower.com/rebates-and-offers directly for any current offers.

Idaho Power is a vertically integrated investor-owned utility regulated by the Idaho Public Utilities Commission and, for its Oregon customers, the Oregon Public Utility Commission. In February 2026, Idaho Power and Oregon Trail Electric Cooperative announced an agreement to transfer Idaho Power's Oregon service territory (approximately 20,000 customers in Malheur, Baker, Grant, Harney, and Wallowa counties) to OTEC. Regulatory filings were made in May 2026 and the transfer is expected to close in early 2027. Oregon-territory customers should confirm current program eligibility with Idaho Power before that transaction closes.
