Park City Offshore Wind is a proposed 791 MW offshore wind generation project located in Massachusetts. The development project, sponsored by ISO-NE, is currently active in the ISO-NE interconnection queue as queue ID ISO-NE-700. The project entered the queue on December 15, 2017, and has a proposed commercial operation date of December 31, 2029. The interconnection agreement has been executed. The point of interconnection is the Eversource 345 kV West Barnstable Substation.
The Park City Offshore Wind project has been the subject of recent news coverage, with 244 articles appearing in the press. These articles primarily focus on regulatory matters, with some coverage of industry, development, and deals related to the project.
