The primary objective of resource adequacy is making sure that there is enough generation capacity available when needed. The MISO is a Regional Transmission Organization and Independent System Operator in the United States that covers approximately 1.05 million square kilometers (406 thousand square miles), serves over 40 million people and comprises 135,000 MW of generation of which currently 11,000 MW is wind, Fig. 1. The wind is located at over 140 sites across the MISO footprint and is comprised of nearly 10,000 separate wind turbines. The MISO also operates a $27.5 billion annual energy market that incorporates 1,975 Commercial Pricing Nodes (CPnodes). MISO is currently adding 1,000 MW of wind on its system every year, and it is expected to have 25,000 MW by 2025. As more new wind resources are being integrated into the MISO footprint and used in meeting the resource adequacy requirements, the capacity value to assign this intermittent resource has taken on ever-increasing importance. This chapter discusses the techniques and processes used to accurately evaluate and assign the correct value of capacity for the wind resources.
