Energy and Environmental Economics (E3) completed the Interim Project Report of the Western Interconnection Flexibility Assessment. This is a collaborative project among WECC, WIEB, NREL and E3 to investigate the operational challenges of increasing levels of variable generation in the Western Interconnection and to explore potential solutions for the adequate flexibility in the power system. This interim report provides an update on the data and methodology for the project, and results from the first phase analysis of the Loss of Load Probability assessment of reliability in each region of the Western Interconnection. The second phase will explore the operational flexibility issues and should be completed in August, 2015.
