Click Here to Link to National Grid System Information Portal*
National Grid has created a collection of maps to help customers, contractors and developers identify potential project sites. The map provides the location and specific information for selected electric
transmission lines, distribution lines and associated substations within the National Grid service NY electric service area. National Grid’s electric system is dynamic. System configurations can change for a variety of reasons both planned and unplanned. National Grid will update the contents on a periodic basis so be aware
that the same location may show different information over time.
Please note that the portal and maps are not a guarantee that generators can interconnect at any particular time and place. A number of factors drive the ability and cost of interconnecting distributed generation to the
electric system and actual interconnection requirements and costs will be determined following detailed studies. These studies will consider your specific project location, operating characteristics and timing.
Additionally, environmental and other required permits are independent of our interconnection process and may limit the suitability of a particular site.
Detailed information on this process can be found at: https://www9.nationalgridus.com/niagaramohawk/business/energyeff/4_interconnection.asp
