Brattle Analysis: 8,000 MW to 24,000 MW of U.S. Offshore Wind Proposals will Require up to 3,000 Miles of Offshore Transmission
“Most of the proposed offshore wind developments will require 30 to 60 miles of offshore transmission to reach the shore,” noted Brattle Principal Johannes Pfeifenberger, a co-author of the study. “If constructed as generation tie lines to individual wind farms, 20 individual transmission lines (each able to serve a 400 MW wind plant) would be needed to interconnect the 8,000 MW of committed offshore wind developments. Our analysis shows that, at this scale of offshore wind development, the development of offshore transmission grids that can interconnect multiple wind plants can offer significant advantages over reliance on individual generation tie lines.”
The advantages of offshore grids to integrate the large scale of proposed wind developments include:
- Lower cost due to scale economics
- Improved use of right-of-ways and lower environmental impacts due to fewer landing points that disturb coast lines
- Increased redundancy for delivering offshore wind generation
- The ability to reinforce the onshore grid with the offshore transmission network
- Open access to enable more competition between wind developers
- Ability to introduce competition among experienced transmission developers

Tractebel is part of the Consortium that has been awarded a contract for the construction and installation of the Seamade offshore wind farms in the North Sea. The consortium will build the two high voltage substations, and their respective substructure, to be installed respectively in the Mermaid and the Seastar area.
Tekmar Energy are pleased to announce that international marine contractor Van Oord has selected the patented Tekmar Cable Protection System (CPS) TekLink® Mechanical Latch for the Borssele 2 (site III and IV) offshore wind farm.
