Desert Southwest has been asked to participate in a study that would look at the benefits of joining either the proposed Southwest Power Pool Western Energy Imbalance Service (WEIS) or California Independent System Operator Energy Imbalance Market (EIM).
DSW projects operate from the Western Area Lower Colorado (WALC) Balancing Authority (BA). The status quo operating strategy for WALC is becoming increasingly unsustainable. Our current process of using residual hydro capacity which is not being used to serve Firm Electric Service and supplementing with real-time purchases for balancing BA loads is most likely not maintainable due to power availability and cost, as more renewables are interconnected to the bulk electric system. DSW needs to identify the best path forward to be prepared for the future.
