GridEx: How NYISO Joins the Nation to Promote Grid Security

November 16, 2021

Every two years, the nation’s largest grid security exercise, GridEx, is conducted by the North American Electric Reliability Corporation (NERC). GridEx is a grid security simulation that takes place across North America, allowing utilities and organizations such as the NYISO to test their response to and recovery from simulated, coordinated, cyber and physical security threats and incidents.

GridEx is one of many efforts the NYISO undertakes to maintain grid reliability in the face of cyberattacks and other threats. We have a comprehensive program to address physical and cybersecurity risks. These programs draw from both industry standards and mandatory NERC guidelines. NERC is a regulatory authority that oversees the reliability and security of the energy grid in North America.

We protect our critical infrastructure assets with a variety of processes, technology and skilled staff. We also routinely collaborate with state and federal government and law enforcement, along with other ISOs and industry partners around the continent. Our physical and cybersecurity measures far exceed NERC requirements.

During GridEx, about 60 NYISO staff will take part directly, but response simulations involve thousands of participants. The exercise will include staff from IT and operations at NYISO. In addition, members of NYISO’s corporate communications team will engage in crisis exercises.

Around New York and the surrounding regions, numerous utilities, industry stakeholders, governments and other critical infrastructure partners will be participating in the exercise. Officials from the N.Y. State Police, the Office of the Governor, the N.Y. State Public Service Commission and the Northeast Power Coordinating Council will observe the event.

What is learned from these exercises? Thank you to GridEx, participants can practice and improve responses to security events, communication channels between participants, and apply lessons learned to improve response plans.

We are an independent, not-for-profit corporation responsible for operating the state’s bulk electricity grid, administering New York’s competitive wholesale electricity markets, conducting comprehensive long-term planning for the state’s electric power system, and advancing the technological infrastructure of the electric system serving the Empire State.
