Upcoming E-TWG Meeting

May 2nd,  Building Energy Exchange, Manhattan

2024 State of the Science Workshop, July 16th-19th, Stony Brook University, Long Island, New York.

The New York State Environmental Technical Working Group (E-TWG) is a team of stakeholders that provides advice on how to advance offshore wind energy development in environmentally responsible ways. 

What is the Environmental Technical Working Group (E-TWG)?

The E-TWG is an independent advisory body to the State of New York with a regional focus on offshore wind and wildlife issues in the eastern U.S. It is comprised of offshore wind developers and science-based environmental non-government organizations (NGOs), as well as state and federal wildlife regulatory agencies. 


The E-TWG helps promote environmentally responsible advancement of offshore wind development through (1) regional collaboration and (2) advice and guidance to New York State.

E-TWG Objectives

  • Improve our understanding of, and ability to manage for, potential effects of offshore wind energy development on wildlife.

  • Develop transparent, collaborative processes for identifying and addressing priority issues relating to wildlife monitoring and mitigation.

  • Reduce permitting risk and uncertainty for developers by improving clarity in expectations and processes for wildlife monitoring and mitigation.

Who We Are

The E-TWG is led by the New York State Energy Research and Development Authority (NYSERDA), and includes offshore wind developers with active leases between Massachusetts and North Carolina; science-based environmental NGOs with expertise on offshore wind energy issues; state agency representatives from Massachusetts to Virginia; and federal agencies with offshore wind and wildlife jurisdiction.
