The Western Energy Imbalance Market (WEIM) allows participants to buy and sell power close to the time electricity is consumed, and gives system operators real-time visibility across neighboring grids. The result improves balancing supply and demand at a lower cost. The WEIM platform balances fluctuations in supply and demand by automatically finding lower-cost resources to meet real-time power needs. The WEIM manages congestion on transmission lines to maintain grid reliability and supports integrating renewable resources. In addition, the market makes excess renewable energy available to participating utilities at low cost rather than turning the generating units off.More specifically, regional coordination in generating and delivering energy produces significant benefits in three main areas:
The WEIM is managed by a five member Governing Body.
