Brattle Principal Johannes Pfeifenberger, Senior Consultant Pablo Ruiz, and Kai Van Horn of National Grid USA have coauthored a study estimating transmission-related benefits attributable to the geographic diversification of variable renewable generation and loads. The analysis, published by Boston University’s Institute for Sustainable Energy (BU-ISE), indicates that the benefits of transmission expansion between areas with diverse renewable generation resources are greater than typically estimated, with significant reductions in system-wide costs and renewable generation curtailments in both hourly day-ahead and intra-hour power market operations. The benefits are substantial and yet often not accounted for because they are more difficult to model.
