Distributed Generation

Distributed generation is electrical generation provided by relatively small, grid-connected installations. Vermont has a range of programs described below.  

For more information or to submit an application, please contact nmapplication@vermontelectric.coop. VEC recommends that all applicants over 15kW to take a look at VEC’s interconnection guidelines for distributed generation.

Net Metering

Net metering is a program that allows members to connect small-scale, distributed generation renewable energy systems  to the grid and receive credit on their electric bills. Learn more about net metering with VEC generally, and see VEC's interconnection procedures specific to net metering.

Power Purchase Agreement (PPA)

VEC may offer direct power purchase agreements (PPAs) Power Purchase Agreement (PPA) when VEC considers the interconnection to be mutually beneficial. Please reach out to our Power Planning group at nmapplication@vermontelectric.coop for more information. PPA projects are governed by PUC Rule 5.500. 

Grid Data

For planning purposes, VEC has developed a map (below) to assist in the location of new distributed generation facilities. The map includes several layers such as poles, wire, substation locations, and generation constraints. These layers are updated monthly. To download layer files please click here.

Note on Grid Constraints 

VEC recommends that any new electricity generation be located outside of the Sheffield Highgate Export Interface (SHEI). The SHEI is an ISO-New England-defined transmission region in northern Vermont. A VELCO-owned 115kV transmission line from Sheffield to Highgate to St. Albans and a GMP-owned 34.5kV sub-transmission line from VELCO East Fairfax to Lowell make up the region. Approximately 21,500 VEC members are fed off of these transmission lines. The area often produces more power than it uses and at certain times of the year there is excess generation that needs to flow out onto the transmission system. The limited capacity of this transmission constrains the amount of power that can be sent to the rest of Vermont and New England. As a result, generation in the SHEI is often curtailed (either shut down or limited).
