The Texas Reliability Entity (TRE) is one of how many regional entities?

The Texas Reliability Entity (TRE) is one of six regional entities recognized within the North American Electric Reliability Corporation (NERC) framework. These entities are responsible for overseeing the reliability of the bulk power system in their respective regions. Each regional entity plays a crucial role in ensuring compliance with reliability standards set forth by NERC, facilitating communication and coordination among stakeholders, and supporting the planning and operating activities within the electric grid.

The other regional entities include the Western Electricity Coordinating Council (WECC), the Electric Reliability Council of Texas (ERCOT), the Midwest Reliability Organization (MRO), the Northeast Power Coordinating Council (NPCC), and the SERC Reliability Corporation. Each performs similar functions tailored to the unique characteristics and challenges of their regions. Understanding the structure of these regional entities is crucial for grasping how reliability is managed across the interconnected North American power grid.
