Idaho Clean Energy Guide
The Gem State benefits from abundant hydroelectric resources that provide clean, low-cost electricity. While Idaho lacks a mandatory RPS, solar development is growing and the state's excellent wind resources present future opportunities.
Policy Overview
Idaho does not have a mandatory Renewable Portfolio Standard, but achieves high clean electricity percentages through abundant hydroelectric resources. Net metering is available for solar customers up to 100 kW.
The Idaho Public Utilities Commission regulates Idaho Power and other utilities. PURPA (Public Utility Regulatory Policies Act) contracts have supported some renewable development in the state.
Active Projects & Development
Hydroelectric Legacy
Idaho's hydroelectric dams on the Snake River and tributaries provide reliable, low-cost clean electricity that has powered the state for decades.
Utility-Scale Solar
Idaho Power and independent developers are building solar projects across southern Idaho to diversify the generation mix and meet growing demand.
Micron Technology Expansion
Major industrial expansion in Idaho, including semiconductor manufacturing, is driving demand for clean energy to meet corporate sustainability goals.
Major Developers & Utilities
Idaho Power
Primary utility serving southern Idaho
Avista

Idaho Falls Power
Municipal utility
Market Outlook
Idaho's clean energy market is evolving as load growth and industrial expansion drive need for new generation. Solar-plus-storage offers opportunities to complement the existing hydroelectric base.
Wind resources in southern Idaho could see development, and battery storage is emerging as a grid reliability tool. The state may also see data center development seeking clean, low-cost power.
Grid Operations
Idaho is not part of an organized RTO/ISO market. Idaho Power operates its own balancing authority, while northern Idaho utilities are within BPA (Bonneville Power Administration) coordination. Idaho Power has explored joining CAISO's Western Energy Imbalance Market (WEIM).
