Regional Coordination in the West: Benefits of PacifiCorp and California ISO Integration

This study quantifies the benefits of full operational integration between California Independent System Operator (CAISO) and Pacificorp, a utility that spans six Western states. The study finds that market consolidation could produce between $3.4 billion and $9.1 billion in shared cost reductions in the first 20 years through better grid management and efficiencies gained by planning for the resource needs of a single system.
