A groundbreaking report on offshore wind transmission by consulting firm The Brattle Group, details onshore electric grid cost savings of over $1 billion and significantly reduced environmental impacts in adopting a multi-user, planned transmission system to harness wind power off New England's coast.
The report, Offshore Transmission in New England: The Benefits of a Better-Planned Grid, describes the limitations of connecting each wind farm to shore individually in comparison to a "planned" approach – a high-capacity offshore transmission system serving multiple wind farms, reducing marine cabling and optimizing onshore landing points.
The report will be presented in a webinar with Tufts University and the Responsible Offshore Science Alliance on Thursday, May 14th at 10am. Registration for the webinar is free and open to the public.
Brattle's research underscores the pivotal role of transmission policy in the development of New England's offshore wind industry. The report, prepared for transmission developer Anbaric, found that a planned transmission approach "is likely to result in lower costs in both the near- and longer-term, by lowering risks and costs of onshore upgrades and increasing competition for both offshore transmission and generation." The current approach of relying on individual generator lead lines would require extensive on-shore grid upgrades at an estimated cost that is triple expected for on-shore upgrades in a planned approach, costing ratepayers an estimated additional $1.1 billion overall. By relying on landing points closer to population centers and at robust onshore grid locations, a planned system reduces grid congestion and the need for expensive, disruptive onshore transmission projects that could hinder the growth of offshore wind.
"Substantial additional offshore wind development will be necessary to achieve the New England states' clean energy goals," said Walter Graf, one of the study's co-authors. "At the necessary scale, a planned approach to offshore transmission will significantly reduce the environmental footprint and the overall costs of offshore wind generation."
Among the report's other findings:
"Developing a shared ocean grid is the most effective way to scale offshore wind," said Edward N. Krapels, CEO of Anbaric. "The next phase in achieving states' goals depends on building transmission infrastructure in a way that reduces overall costs, protects fisheries and the environment, and enables continuing growth of New England's best energy resource."
"Transmission is vital for achieving Massachusetts' offshore wind goals," said Patricia A. Haddad, Speaker Pro Tempore of the Massachusetts House of Representatives. "We can green the grid, create jobs, and efficiently reuse coastal power plant sites by developing transmission first, and this study shows why that's a good approach for Massachusetts and New England."
