The Western Energy Imbalance market generated about $100 million in savings in the third quarter of this year, with total benefits reaching $502 million since its launch in November 2014, according to an Oct. 29 press release from the California Independent System Operator Corporation. The third quarter benefits were the highest for any quarter due largely to periods of high demand and fuel prices. Since its launch, the market has delivered 734,437 megawatt-hours of renewable energy that otherwise would have been curtailed. The energy imbalance market is an automated system that secures the lowest-cost energy to serve real-time customer demand over a broad region spanning across multiple western states.
