Resource Adequacy and Reliability

Consistent with the Western Electric Coordinating Council’s (WECC) requirements and prudent utility practices, on April 24, 2006, the Azusa Utility Board adopted a Resource Adequacy program for its electric utility. The program requires that the Electric Utility secure 15% capacity margin for resource planning purposes. Additionally, the California Independent System Operator (ISO) requires that entities serving load in transmission constrained areas secure a specific amount of capacity from resources interconnected in their respective areas of constraint (“local resources”). In that regard, Azusa electric service area which is interconnected in the ISO designated LA Basin area needs to ensure that portion of their resource adequacy capacity is sourced from local resources. 

The list of current resources anticipated to meet adequacy targets are shown here.
