CMPC signs Maine Aqua Ventus power agreement

In: Windfarms
Maine Aqua Ventus I and Central Maine Power Company have officially signed a 20-year Power Purchase Agreement (PPA) for the 12 MW Maine Aqua Ventus floating offshore wind farm located off Monhegan Island. According to the U.S. Department of Energy (DOE), the contract was signed on 9 December 2019.

The state’s Public Utilities Commission approved the PPA in November, 2019. This allows the demonstration project to sell its electricity to the Central Maine Power utility, making it the first DOE-funded offshore wind demonstration project to achieve this milestone.

The University of Maine’s Aqua Ventus I project has been in the planning phase since 2012, and securing a power offtake agreement will help the project attract financial investors and continue further development activities.

The floating offshore wind pilot project aims to demonstrate the viability of floating offshore wind by deploying two turbines on floating concrete semi-submersible foundation designed by UMaine. The foundations will be held in position by three marine mooring lines securely anchored to the seabed, with the electrical generation connected by subsea cable to the Maine power grid on shore.

It is backed by Cianbro Corporation, Naval Group and the University of Maine and UMiane's Advanced Structures and Composite Centre.
The project has secured approximately $39.9 million (€36 m or £31 m ) in funding from the US government. Offshore construction could take place in 2021 provided the project reaches financial close.

The University of Maine successfully deployed and tested a 1:8-scale prototype of their floating VolturnUS foundation in June 2013. The design was tested for almost 19 months between and was the first floating wind turbine connected to the US grid.
