What are the NERC Reliability Standards?

NERC is a non-profit organization that sets industry standards, educates and trains industry personnel and provides guidelines for grids. You can find the details on NERC and NERC reliability standards in our article.

What is NERC?

NERC refers to the North American Electric Reliability Corporation. It is a non-profit organization whose main aim is to provide necessary regulations that reduce the risks regarding reliability and security.

In addition to setting regulations, responsibilities of NERC also includes overseeing and enforcing compliance with industry standards and regulations, assessing and inspecting grids in regards to the efficiency and adequacy of resource use, educating, training and certifying personnel for the industry.

When a significant issue regarding the power systems occurs, NERC has the duty of investigating this incident in order to detect the reason and prevent further disturbances.

Furthermore, NERC also runs the Electricity Information Sharing and Analysis Center (also known as E-ISAC). E-ISAC provides threat intelligence regarding cyber and physical security and offers expertise and consultancy in these areas.

What are the NERC Reliability Standards?

NERC Reliability Standards aim to regulate and ensure the quality of North American bulk power system. They set the minimum requirements regarding the reliability, efficiency, safety and risk management of operations that provide bulk power within the borders of the United States, Canada and Mexico.

NERC Reliability Standards define the requirements for both planning process and operations of the bulk power providers and systems in the areas mentioned above. If your business operates in a field concerning the distribution or production of bulk power, you need to make sure that your operations comply with the NERC Reliability Standards. Below you can find further information.
