With the changing composition, location, and operational characteristics of the electricity generation fleet, such as the development of remote renewable generation and retirement of coal-fired power plants, the importance of transmission planning and operations is rising. 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 policy study released by the office since it was created in 2003, and it continues to leverage this knowledge to address timely transmission-related issues.
