New York System Data Portal

National Grid is dedicated to creating and delivering resources to support developers and contractors across our territories. For our New York (NY) developers and contractors, we recently created a NY System Data Portal — an online, interactive mapping portal that provides real-time visibility into the electric grid distribution system.

The portal contains distribution feeder and substation information, including:

  • Feeder characteristics, such as geographic locations

  • Voltage information

  • Feeder ID

  • Planning area

  • Substation source

  • Loading and available hosting capacity

We encourage you to visit the portal and use the real-time information to develop your future projects.

We are always looking for ways to best support developers and contractors across our territories. We want to hear from you! If you have any questions, comments, and/or suggestions regarding the portal, please contact
