- Electric Reliability Council of Texas (ERCOT), which covers approximately 75 percent of the land area in Texas and represents about 90 percent of the state’s electric load;
- Midcontinent Independent System Operator (MISO), which has a presence in east Texas;
- Southwest Power Pool (SPP), which covers the panhandle and the northeast corner of Texas; and
- Western Electricity Coordinating Council (WECC), which provides for the western most part of the State
There are a total of eight reliability regions in the continental United States, and each of these regions is subject to the oversight and enforcement authority of the North American Electric Reliability Corporation (NERC).
NERC is responsible for developing standards to ensure and improve reliability for the delivery of electricity on the bulk power system. Furthermore, NERC is subject to the Federal Energy Regulatory Commission’s (FERC) oversight. FERC works to assist consumers in obtaining reliable, efficient and sustainable energy services at a reasonable cost through appropriate regulatory and market means.
AECT has member companies representing each of these entities and consequently, each of these reliability regions.
