This innovative project was completed by RETTEW, the nation’s premier engineering and EPC contractor for floating solar applications. US Floating Solar is a long standing RETTEW partner developing opportunities in the floating solar and renewable energy market.

Sayreville, NJ 4.41MWdc Floating Solar Project


With a strong desire to reduce both energy costs and the town’s carbon footprint, Sayreville issued a public RFP in late 2015 calling for developers to provide bids for a solar installation under a power purchase agreement (PPA) to offset power use at the water treatment facility and related Borough facilities such as Borough Hall and the Public Works Building. Due to a lack of available land, this proved to be an ideal opportunity to propose a floating solar power system for the nearby pre-treatment pond. The floating solar system will supply approximately 5,000,000 kWh of solar electricity annually, representing 100% of Sayreville’s energy requirements for its water treatment plant.


Borough of Sayreville had rising electrical costs from energy procurement and a desire to be sustainable throughout the Borough’s operations


Through a Power Purchase Agreement the Project Team members designed, built, own and operate a 4.41MWdc floating solar array


Over $150,000 per year in savings to the Borough in Year 1 and long-term sustainability to meet future regulatory and political goals
