The state has awarded a $522,500 grant to the Great Neck Water Pollution Control District to help fund construction of two microturbines.

The district plans to build the turbines to convert methane produced during the treatment of sewage into electricity that would help power the facility.

The estimated yearly savings would be $93,000.

The total cost for the project is estimated at $1.2 million.

The state Environmental Facilities Corp.’s Green Innovation Grant Program awarded $15 million to 40 municipalities, nonprofits and businesses throughout the state.
