Balancing authorities are responsible for maintaining operating conditions under mandatory reliability standards issued by the North American Electric Reliability Corporation and approved by the U.S. Federal Energy Regulatory Commission and, in Canada, by Canadian regulators. . For a small number of plants, we also use the plants NERC Assessment Area. Your input and feedback is greatly appreciated. GGL is calculated by dividing the estimated losses by the result of total disposition minus net interstate exports minus direct use: The U.S. Energy Information Administration (EIA) provides data on estimated losses (reported at the utility level via form EIA-861, and then allocated to States based on the utility's retail sales by State), total disposition (i.e., the sum of station use, direct use, retail sales, sales for resale, and other outgoing electricity), net interstate exports, and direct use (i.e., electricity consumed onsite for all operations other than electric power plant station use) at the state level in the State Electricity Profiles. Regional energy information including dashboards, maps, data, and analyses. The California Independent System Operator (CAISO) is the largest of about 38 balancing authorities in the western interconnection coordinating council (WECC), handling an estimated 35 percent of the electric load in the west. In eGRID2012, the map identified secondary and tertiary subregions; however, starting with eGRID2014, the maps simply indicate areas that fall into more than one eGRID subregion without identifying secondary and tertiary subregions. [7] Frequently the same utility plays multiple roles, for example, CAISO, in addition to being an independent system operator, is also operating under the name RC West as a reliability coordinator for 42 balancing authorities and transmission operators in the Western interconnection.
