Report Finds $500M in Cost Savings and Reduced Environmental Impacts and Risk with Planned Offshore Wind Transmission for New York
WAKEFIELD, Mass., Aug. 6, 2020 /PRNewswire/ -- A new report on offshore wind transmission by economic consulting firm The Brattle Group finds electric grid cost savings of over $500 million and significantly reduced environmental impacts and project risks in developing a multi-user, planned transmission system for offshore wind in New York. The report, Offshore Wind Transmission: An Analysis of Options for New York, evaluates the challenges of connecting each wind farm to shore individually in comparison to a planned approach—a high-capacity offshore wind transmission system serving multiple wind farms, reducing marine cabling, and optimizing onshore landing points and electric substations.
The report will be presented in a webinar co-hosted by Anbaric and the New York League of Conservation Voters Education Fund on Thursday, August 6th at 10 a.m. The event is co-sponsored by Columbia University's Sabin Center for Climate Change Law and registration is free and open to the public.
Brattle's research, supported by engineering firms PTerra and Intertek, underscores the pivotal role of transmission planning in the development of New York's offshore wind industry. The approach of relying on individual generator lead lines would require extensive onshore grid upgrades costing four times as much as a planned approach. By using fewer cable routes and more robust grid connections, a planned transmission system reduces grid congestion and the need for expensive, disrutive onshore transmission upgrades, thereby also reducing the impacts on the marine environment and coastal communities.
"Substantial additional offshore wind development will be necessary to achieve New York's clean energy goals," said Johannes Pfeifenberger, a Brattle principal and a study coauthor. "At the scale considered by New York, a planned approach to offshore transmission will significantly reduce the environmental footprint and the overall costs and feasibility risks of offshore wind generation."
Among the report's other findings:
"Developing a shared ocean grid is critical to achieving New York's ambitious offshore wind goals," said Kevin Knobloch, President of Anbaric's New York OceanGrid. "The next phase in achieving New York's goals depends on building transmission infrastructure in a way that reduces overall costs and feasibility risks, protects fisheries, coastal communities and the environment, and enables developing the offshore wind industry to scale."
