Idaho Energy Storage Policy and Market Overview
Idaho’s energy storage market is youthful and indicates signs of future growth. Utility and state regulators are targeting grid-scale battery procurement to secure resilience and reliability for rural communities in the state.
In 2022, market opportunities for storage emerged when Rocky Mountain Power expanded its Wattsmart Battery Rebate to Idaho’s service area. The rebate offers critical incentives to BTM customers and kickstarted the storage charge. In 2023, Idaho broke ground on the first grid-scale battery energy storage project. However, only a few other projects have since joined the charge. Idaho Power Company has set short term goals on a 300 MW project that expects to be online in 2026. The utility’s long-term goals aim for 1,685 MW by 2040. Legislators have issued some regulatory guidance on energy storage and set codified operational definitions via HB 96 (2023).
