We qualitatively and quantitatively examined two approaches to developing offshore transmission and associated onshore upgrades to reach New England’s offshore wind (OSW) development goals.
- The current approach wherein OSW developers compete primarily on cost to develop incremental amounts of offshore generation and association project-specific generator lead lines (GLLs)
- An alternative “planned” approach wherein transmission is developed independently from generation. Offshore transmission and onshore upgrades are planned to minimize overall risks and costs.
We conduct analyses of potential OSW-interconnection configurations for two levels of future offshore wind development. While other transmission configurations are possible, those captured here are representative of likely outcomes.
- The analyses reflect current trends in how and where developers cite generator lead lines
- We highlight an alternative outcome that is unlikely to occur without a planning process
