Renewable energy
At the heart of what we do, National Grid Ventures is working to accelerate the development of our clean energy future. In support of this goal we’ve made significant investments in large-scale renewable energy projects, including wind, solar and battery storage.
Additionally, we’ve made investments in community and residential solar to develop the potential of grid services using cleaner, renewable sources of energy.
Battery energy storage systems
As an alternative to building new transmission or fossil-fired peaking capacity, we have partnered with NextEra Energy Resources in the development of two battery energy storage systems on Long Island. These include 5 MW, 40 MWh battery energy storage systems in both East Hampton and Montauk, New York.
The systems have helped decrease emissions and enabled peak-shaving during the busy summers on the southeast end of Long Island.
Community and residential solar
We’ve partnered with San Francisco-based Sunrun, a leading provider of residential solar and battery storage in the U.S., since 2016. The collaboration has included a USD $100 million asset investment and employees from each company working to develop the potential of grid services using cleaner, renewable sources of energy.
The partnership has also included joint marketing, leveraging both companies’ strong brands, to accelerate the adoption of rooftop solar in a cost-effective, highly-scalable way.

Estimated project benefits and impacts
* Data derived from and associated with renewable energy projects under construction or in operation by affiliates of National Grid Renewables. Environmental benefits calculated using the United States Environmental Protection Agency’s (EPA) greenhouse gas equivalencies calculator. Environmental benefits are singular, not additive. Environmental benefits represent annual estimated amounts. Economic benefits calculated based on National Renewable Energy Laboratory (NREL) JEDI Model, National Grid Renewables models, and current tax law for renewable energy facilities. Economic benefits represent estimated total impact over the first 20 years of operation. All project production, benefits, and amounts are estimates and not guaranteed.
