Idaho Power Co

Idaho Power's optional residential Time-of-Use plan, Schedule 5, separates summer energy costs into three periods: On-Peak from 7 p.m. to 11 p.m., Mid-Peak from 3 p.m. to 7 p.m., and Off-Peak from 11 p.m. to 3 p.m., all Monday through Saturday, with all day Sunday and holidays billed at the Off-Peak rate. The summer Off-Peak rate is substantially lower than On-Peak, so owners who can shift EV charging to overnight and early-afternoon hours pay less than they would on the standard residential rate. Non-summer hours are simpler: On-Peak runs 6 a.m. to 9 a.m. and 5 p.m. to 8 p.m. Monday through Saturday, with all other hours Off-Peak. A TOU Trial option launched January 1, 2026 lets new enrollees 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 EVSE Incentive Offering, aimed at businesses and municipalities rather than individual homeowners, is no longer offered. It used to pay 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, and up to $20,000 per site for DC fast chargers and other fleet electrification equipment. As of September 1, 2026, Idaho Power's program terms and application pages return not-found errors, and AFDC lists no current non-residential EV charging incentive for Idaho Power. No residential EVSE rebate is offered either; Idaho Power's own rebates page does not list one as of September 1, 2026.

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.
