Bonneville Power Administration (BPA) proposes to enter into a coordinated transmission agreement with the California Independent System Operator (CAISO) that would formalize existing practices and data exchanges between BPA and CAISO, as well as improve the management of energy-imbalance market flows on our interconnected transmission systems. The agreement provides for coordinated operations between BPA and CAISO to ensure system reliability when adjacent balancing-authority areas utilize BPA’s transmission system to make real-time power transfers while participating in CAISO’s Energy Imbalance Market.
