Regional entity


A regional entity in the North American power transmission grid is a regional organization representing all segments of the electric industry: electric utilities, federal agencies, independent power producers, power market operators, and end-users of the energy. North American Electric Reliability Corporation delegates to REs authority to enforce reliability standards, collectively REs, together with NERC, are known as an "ERO Enterprise".

History

The regional entities, at the bottom of the structure for the development and enforcement of the reliability standards for the US electric grid, were established by the Section 215 of the Federal Power Act as amended by the Energy Policy Act of 2005. The statute tried to mimic the balance of power between the federal and state authorities in the US, with REs playing the role of regional components.
As of 2021, there were six regional entities:
The original list included eight entities, two REs were later dissolved:
The reliability standard development process had Regional Entities developing regional standards, to be approved by NERC and FERC. By the 2010, the process was slow: just nine standards were developed, all by the WECC.
An RE approves the transmission plans and chooses the projects for regional cost allocation.
One of the important roles of an RE is suggesting to NERC to include the facilities into - or exclude from - the list of "elements" that constitute the bulk-power system, subject to the oversight of the NERC.
