USA, Montana, Butte: The real-time wholesale energy market now includes a Montana-based utility.
The Western Energy Imbalance Market (EIM), operated by the California Independent System Operator (ISO), has expanded its footprint to Montana with the addition of NorthWestern Energy.
NorthWestern Energy’s participation caps off a year of significant growth for the real-time energy market, with eight utilities joining already this year. The Western EIM now serves consumers in 10 states, including portions of Arizona, California, Idaho, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming, and Montana. By 2023, 22 active Western EIM participants will represent more than 83 % of the load in the Western Interconnection.
“We are very pleased to welcome NorthWestern Energy into the family of Western EIM entities,” said ISO President and CEO Elliot Mainzer. “This new partnership with NorthWestern will add regional diversity and diverse resources into the real-time energy market and provide additional economic and environmental value to consumers in Montana and across the West.”
Since its launch in 2014, the Western EIM has been using advanced technology to find and deliver the lowest-cost energy to utilities, while enhancing reliability and reducing greenhouse gas emissions. The most recent quarterly results show the Western EIM has achieved $1.28 B in cumulative gross benefits for its participants.
NorthWestern Energy provides electricity and natural gas to more than 743,000 customers in Montana, South Dakota, and Nebraska.
