Is a home battery worth it in Idaho?

In 2026 the main battery value in Idaho is time-shifting your own solar to dodge poor off-peak export credits and use it during higher on-peak windows, not backup and not a state rebate. There is no state or Idaho Power residential battery incentive, and the federal purchase credit is gone for cash buyers.

Idaho at a glance

Average residential rate: 13 cents per kWh
Net metering: No statewide net-metering mandate. Each investor-owned utility runs a PUC-approved net-billing tariff. Idaho Power pays a time-differentiated Export Credit Rate, not retail. As of March 2026 the ECR is about $0.157/kWh on-peak summer but only about $0.029/kWh off-peak, and around $0.034 on-peak in non-summer months, so most exports earn well below retail. A Sept 2025 PUC order capped further ECR cuts at 40% and paused annual updates until 2028. Pre-2019 systems grandfathered through 2045.
State battery incentive: None we can source for 2026

What drives battery value here

Generally reliable grid; exposure is mainly wildfire-season public-safety shutoffs and winter storms in rural mountain areas. Backup is a secondary driver; outages are not frequent for most customers. Batteries mostly earn their keep by self-consuming solar that would otherwise export at the low off-peak ECR.

The federal picture in 2026

The federal residential purchase credit (Section 25D) expired on December 31, 2025, so a 2026 cash buyer gets nothing federal. The only surviving federal pathway is Section 48E, which a company claims on a lease or PPA. State and utility programs, where they exist, now do the heavy lifting.
