Celtic Sea Developer Alliance

The CSDA is an alliance of Floating Offshore Wind developers with an interest in the Celtic Sea region. We work collaboratively to promote the crucial role this renewable technology will play in the UK’s drive to Net Zero.

The Marine Energy Wales website will be upgraded in the near future along with this page.
