Hosting Capacity Map

To help distributed generation contractors and vendors select locations for interconnections to Eversource’s system in Massachusetts, maps detailing the hosting capacity by circuit are now available.

Each circuit on our system is displayed with a color matching its remaining capacity. Clicking on a circuit will also bring up an information box providing more detail about the circuit, its remaining capacity and related substation.

This information shows the capacity Eversource’s infrastructure can handle with limited system upgrades while still reliably and safely delivering electricity to our customers.

Capacity on the circuits and at substations can be increased through project funded upgrades. Small, limited size projects may still be supported without project funded upgrades.

Answers to frequently asked questions about the hosting capacity map are also available.
