Bay State Wind has signed a letter of intent (LOI) to collaborate with NEC Energy Solutions to develop an energy storage system for its 800MW wind/55MW – 110MWh energy storage combined project, which will be located in Massachusetts, US.

The project is expected to be the world’s largest wind-paired energy storage system for commercial-scale energy.

Bay State Wind is the 50/50 partnership between Ørsted and New England’s transmission builder Eversource.

Under the deal, the company have agreed to accelerate the development of early commercial integration of storage technologies into the electricity supply chain.

The deal will also capitalise on storage technology’s benefits to clean energy integration, grid reliability, system-wide efficiency, and system peak demand reduction.

“It will help solidify Massachusetts as a global leader in the green energy revolution.”

Eversource business development vice-president Mike Auseré said: “The development of a robust battery storage system is going to help Massachusetts become a leader in renewable energy, and more importantly, it will help small businesses and consumers by ensuring a steady supply of energy, thereby reducing high-demand energy spikes.”

The deal will expand Bay State Wind’s commitment to supporting and promoting energy storage in Massachusetts.

Ørsted North America president Thomas Brostrøm said: “We could not be more thrilled to work with a Massachusetts company that is a global leader in battery storage technology and products.

“NEC Energy Solutions is widely recognised as a pioneer and leader in the market for utility-scale energy storage, and their ability to recruit talent from the local workforce will help not only Bay State Wind, but it will help solidify Massachusetts as a global leader in the green energy revolution.”

It is reported that NEC Energy Solutions’ expertise in developing flexible battery storage solutions will advance Bay State Wind’s efforts to help the region in overcoming winter reliability challenges by delivering energy and help to reduce winter peak energy prices and price volatility.

NEC Energy Solutions CEO Steve Fludder said: “Bay State Wind brings industry leadership that is second to none.

“This development is crucial to growing our battery storage systems in Massachusetts, across America, and around the world. The Bay State Wind project is a unique opportunity and the benefits to the Commonwealth are immense.”
