High-voltage substation construction and transformer work across Idaho. Here is the grid ESS operates in.
Hydropower is Idaho's largest electricity source at roughly 44 percent of generation, led by Idaho Power's Hells Canyon Complex on the Snake River. Natural gas supplies about 31 percent and wind about 15 percent, with additional contributions from geothermal, solar, and biomass. Idaho has no coal-fired power plants within the state and imports roughly a third of the electricity it consumes from the regional market.
Drought and reduced snowpack have lowered hydroelectric output, cutting hydropower's share of generation from about two-thirds in earlier decades to roughly 44 percent. Because the state produces less than half of the electricity it uses, Idaho relies on imports and market purchases and is exposed to regional supply and price conditions. Idaho Power and Rocky Mountain Power are advancing the roughly 290-mile Boardman to Hemingway 500kV line to expand transmission capacity between the Pacific Northwest and southern Idaho.
Shown as regional context, the major electric utilities and grid organizations operating in Idaho. ESS builds substations and installs EHV apparatus across the western grid and has mobilized wherever the work is since 1978.
