Offshore Wind farms in The United States

The United States has 192 offshore wind farm projects of which 3 currently operating, 2 where construction has progressed enough to connect the turbines and generate electricity, none are in the build phase, and 16 are either consented or have applied for consent. You can access over 80 data sets on each wind farm subject to your access level and drill down to see items such as:

on project 'South Fork' on Monday, 01 April 2024, the following was announced: 'Update (November 2023): Eversource has confirmed an 'early 2024' commissioning date.

Previous: Based on timelines suggesting first power by end-2023, assume full commissioning in H1 2024.'

How does the database work?
