Thermal (Capacity) Ratings of Electric Power Facilities & NERC Compliance

Any owner and/or operator of electric power facilities and equipment should have a vested interest in knowing the capacity ratings of their system’s ability to transfer electric power. In the United States, owners and operators of interconnected electric transmission facilities are governed by the regulations and standards published by the FERC and NERC. One purpose of these regulatory agencies is to ensure a reliable transmission network that is designed and operated according to a uniform set of practices. For owners of electric power facilities that are not governed by FERC and NERC, or facilities that reside in countries outside the United States, should also consider a uniform documentation and ratings process for efficient and reliable use of their electric power facilities.

OrionMagnetics is a world leader and innovator of engineering services and solutions in the area of capacity (i.e. thermal) ratings of electric power equipment.
