The New York Independent System Operator (NYISO) is responsible for the reliable operation of New York’s nearly 11,000 miles of high-voltage transmission and the dispatch of more than 500 electric power generators. In addition, we administer bulk power markets that trade an average of $7.8 billion in electricity and related products annually.

As a not-for-profit independent system operator, we are governed by a 9-member Board of Directors. Market Participants and Stakeholders in New York’s electricity markets play a significant role in our unique shared governance process.

We employ more than 550 people and occupy two locations in New York's Capital Region. Given the technical complexity of our mission, over a quarter of the company’s staff are devoted to the development and support of information technology. We have a diverse and engaged workforce, and have been recognized as a top employer in the region.
