In this section you will find information pertaining to net metering and the safe interconnection of generators to the NSTAR electric power system.

Such interconnections include photovoltaic arrays (solar panels), mini-turbines, wind turbines, cogeneration units and micro turbines, to name a few.

All regulations and fees have been filed and approved by the Massachusetts Department of Public Utilities (DPU).

Interconnections for facilities that are 500 kW or greater need to request and receive a Pre-Application Report from NSTAR before submitting an application.

Interconnections for facilities that are 5,000 kW or greater need to contact ISO New England for instructions for asset registration for their project. Projects of this size cannot be registered by NSTAR as settlement-only resources, and must comply with ISO New England Operating Procedure #14 as well as other requirements.
