The Acadia microgrids are scalable projects combining renewable energy and storage, offering green, resilient power to support local economic growth and sustainability in line with IRA and CLCPA goals.

The two companies will share the project costs and equity requirements equally, with each party contributing 50% of the necessary financing.

Acadia has an existing potential project pipeline of over 1.5 - 2.0 gigawatts of renewable energy projects in New York with an average size of 20 – 50 MW per project, and is currently in discussions with various regulatory agencies regarding microgrid implementation.

The projects in the joint venture are expected to begin achieving commercial operations within 2 years.
