Offshore Wind Accelerator: Connecting to converter dominated AC onshore and DC offshore networks

Call for proposals from companies and consortia interested in undertaking a study to understand the practical capabilities and physical implications of designing and operating grid forming offshore wind farms.

The main objectives of this work are to establish the key points below.

  • To identify the risks of weak grids, both onshore and offshore, and the associated metrics which characterise weak grids, both onshore and offshore.
  • To provide guidance or tools to identify weak grid scenarios.
  • To provide mitigation methods for connecting and operating in these weak grid areas, including the identification of studies and to establish who should undertake the studies/assessments.
  • To create a guideline for developers on how to design, model and operate an offshore windfarm in weak grid areas.

Clarification questions should be received by 18 September 2023, 17.00 BST and the answers to these questions will be posted below on 25 September 2023. 

The closing date to receive tender submissions is 9 October 2023, 17.00 BST.
