National Grid New York

System Data Portal

 

 

National Grid has created a collection of maps to help customers, contractors and developers identify potential project sites. Each map provides the location and specific information for selected electric distribution lines and associated substations within the National Grid 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: (nCAP) Customer Application Portal.

 

Will the maps be made available directly in a downloadable format?
At this time, National Grid does not anticipate making the maps available in any other downloadable format due to the dynamic nature of National Grid�s electric system and the prospect of different users having files with different system configurations.   To ensure that National Grid is providing authoritative content the company must be able to maintain its content in an authoritative format.

 

Are instructions for using the portal available?

To help enable the use of the portal National Grid has provided a guide in pdf format.   This can be accessed here:   System Information Portal Help
