Maine Aqua Ventus GP LLC Releases Public Version of MPUC Proposal

This morning, Maine Aqua Ventus GP LLC released the public version of its proposal to develop a groundbreaking offshore wind project in the Gulf of Maine, called Maine Aqua Ventus I. Maine Aqua Ventus I is the state’s only still-active offshore wind opportunity and is competing nationally against projects in five other states for grant funding from the U.S. Department of Energy.

“The PUC power-purchase agreement is the next step in securing the DOE grant, which is critical for the success of this important project for our state,” said Jake Ward, speaking for Maine Aqua Ventus I. The project is Maine’s entrant in the competition against other projects located in New Jersey, Virginia, Texas, Ohio and Oregon. [Full list provided below as Appendix A]

In a unique opportunity for the state, Maine Aqua Ventus I was designed in Maine specifically to be deployed off the coast of Maine and will be built by Maine institutions and workers. As is clear from this newly-released proposal, the project represents a historic opportunity for Maine to be the leader of an important new offshore wind industry.

This public version of the Maine Aqua Ventus I proposal is another step in the Maine Public Utilities Commission process for approval of a power-purchase agreement. It does not contain technically-sensitive information or information reserved for the forthcoming Term Sheet, in compliance with PUC precedent. The Term Sheet will be released in the next few weeks after Maine Aqua Ventus I GP LLC and the PUC agree on terms, which are still in the final stages of negotiation. 

The document released today describes:

  • The project partnership and provides information on companies involved in this project. [A representative list provided below as Appendix B]
  • The U.S. Department of Energy grant process – which calls for a pilot offshore wind project to demonstrate advanced technology to lower energy costs.
  • The project’s technology in detail, including the floating submersible concrete hulls and the 270-foot-tall composite tower.
  • Two 6 MW direct drive, permanent magnet turbines, which are designed for offshore projects.
  • Maine Aqua Ventus I will be constructed on land and dockside reducing risk and cost.
  • The data collection process that will follow the demonstration phase and suggest technological and process improvements toward reaching the DOE goal of 10 cent per kilowatt hour energy by the 2030s.
  • Maine Aqua Ventus GP LLC’s commitment to supplying Monhegan Island with electricity to meet its current needs at no generation cost to reduce its reliance on fossil fuels generation which is priced at 70 cents per kilowatt-hour. It also describes the transmission line that will run from Monhegan to the mainland (and connect the island to both the electric grid and to high-speed internet service).
  • That Maine Aqua Ventus I will be constructed and assembled at Maine ports, of which there are several options, and that the transmission line will connect with the electric grid near Bristol.

Additional information about the project will be released following the completion of a Term Sheet with the Maine PUC which is expected to take place mid-November. The Term Sheet outlines the structure of the power-purchase agreement and the commitments Maine Aqua Ventus makes in order to be allowed to sell power to the grid. The new information that will be available in this document includes:

  • An Economic Impact Statement outlining the benefits Maine communities and workers will see from this project, which will not be complete until additional financial details currently being negotiated with the PUC are finalized in the Term Sheet.
  • The price of the power that will be generated by the project, which is also dependent on these final negotiations.
  • Other important commitments that Maine Aqua Ventus GP LLC will make to the state and its citizens as part of this project.

The public will be given the opportunity to comment on the Term Sheet after negotiations are complete and it becomes public, which is expected to happen mid-November. Additional information on this project is available at
