Abigail Sawyer and Brian Turner of Advanced Energy United and the West Wide Governance Pathways Initiative launch committee discuss the renewed possibility of a seamless, westwide power market that would be governed by a regional organization. The recent passage of California's Assembly Bill 825 cleared the way for California entities to participate in such a market, which, with the load and resources of California's investor-owned utilities, presents a compelling opportunity for non-California entities. Brian also discusses lessons learned from market structures in the Eastern Interconnection and how the California Independent System Operator's extended day-ahead market hopes to avoid making the same mistakes.
