Energy Imbalance Market

Since 2017, we've been saving you money by participating in the Western Energy Imbalance Market , a real-time energy wholesale market that automatically dispatches the lowest-cost electricity generating resources available to meet short-term utility customer needs. The Market optimizes the use of renewable energy across the western United States and a Canadian province.

The EIM uses the latest technology to coordinate power sales and purchases among participating utilities in five- and fifteen-minute intervals, balancing the demand and supply of electricity while making it easier to integrate the variable output of renewables like wind and solar power.

The system is designed to save money for customers while making our power supply cleaner and more secure.

Participating in the EIM is just one way that we are meeting our customers’ energy needs and working with Oregon regulators to plan for our clean energy future.
