Assessment of Historical Transmission Schedules and Flows in the Eastern Interconnection
Understanding and analyzing scheduled and actual flows of electricity on the transmission grid can provide insight into how traditional utilities, power marketers and others use the system. It can indicate where and when the system is heavily or consistently used, and how schedules align with actual use.
There are limited sources of data that provide information on scheduled and actual electricity transfers in the Eastern Interconnection of the United States.1 To address this gap, the U.S. Department of Energy, through the Lawrence Berkeley National Laboratory, issued a contract to Open Access Technology International, Inc. (OATI) to identify and aggregate data describing scheduled transactions and actual flows in the Eastern Interconnection for the year 2010. OATI was directed to aggregate the schedules and actual flows according to the sub-regions within the Eastern Interconnection that had been defined by the Eastern Interconnection Planning Collaborative (EIPC).
This report documents OATI’s data collection and aggregation, and presents the data.
