National Grid
Welcome Change Location

National Grid is dedicated to creating and delivering resources to support developers and contractors across our territories.

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 distributed.generation@nationalgrid.com.
