Berkeley Lab has supported the U.S. Department of Energy’s Office of Electricity Delivery and Energy Reliability in the preparation of every major electricity study released by the office since it was created. These include the following:
- National Transmission Grid Study (2002)
- Final Report on the August 14, 2003 Blackout in the United States and Canada (2004)
- National Electric Transmission Congestion Studies (2006, 2009, and 2015)
- Annual Transmission Data Review (2015)
Berkeley Lab also has helped prepare independent analyses and reviews of selected transmission planning issues.
Transmission System Utilization
In support of DOE’s National Electric Transmission Congestion studies, Berkeley Lab has coordinated the preparation of technical reports on the historic utilization of the transmission systems within the United States’ Eastern Interconnection. These reports parallel analyses of historic utilization of the Western Interconnection that are routinely prepared by the Western Electric Coordinating Council’s Transmission Expansion Planning and Policy Committee. Starting in 2016, the U.S. Energy Information Administration began to make publicly available hourly information on power flows among U.S. balancing authorities, through its U.S. Electric System Operating Data Tool. In addition, Berkeley Lab has conducted reviews of congestion cost methods used by Regional Transmission Organizations (RTOs) and Independent System operators (ISOs).
Support for Oversight of Interconnection-wide Regional Transmission Planning
Following the American Recovery and Reinvestment Act of 2009, Berkeley Lab provided technical support to DOE in managing grants for interconnection-wide planning activities led by the Eastern Interconnection Planning Collaborative, the Eastern Interconnection States Planning Council, the Western Electric Coordinating Council’s Transmission Expansion Planning and Policy Committee, the State-Provincial Steering Committee, and the Electric Reliability Council of Texas (ERCOT).
