Dynamic Transfers for Renewable Energy in the Western Interconnection
A dynamic transfer is a coordinated transfer of firm energy between balancing area authorities. This report provides regulators and policymakers with an examination of historical and emerging uses of dynamic transfers. It also describes the distinct role that dynamic transfers play in keeping integration costs down and evaluates how dynamic transfers relate and interact with the intra-hour scheduling and energy imbalance market (EIM) initiatives in the West. The report considers how the location of renewable generation, balancing resources, and transmission affect the benefits offered by the ability to employ dynamic transfers. It concludes with a discussion of priorities for transmission system capital and operational improvements that could alleviate restrictions on the use of dynamic transfers, and recommends metrics that regulators and policymakers can use to track the progress being made by utilities and balancing authorities in the western states and provinces.
