Mainstream is the most successful independent developer of offshore wind at scale globally. It has developed and consented Hornsea One and developed Hornsea Two totalling 3 GW in England and consented the Neart na Gaoithe offshore wind project in Scotland, 450 MW. These projects represent approximately 22% of the UK’s offshore wind capacity either in operation or under construction.

Global Expansion Offshore

Mainstream continues to extend its offshore wind development credentials. In Vietnam, it is developing one of Asia’s largest offshore wind farms, the 1.4 GW Soc Trang project through a JV with local company, the Phu Cuong Group. In 2020, it also announced agreement to co-develop 500 MW offshore in the Ben Tre province, Vietnam with local company, AIT Corp.

In the US, Mainstream has received full qualification to apply for a lease in both the New York Bight, and California. Both lease auctions are expected in 2021. Mainstream is reviewing further opportunities in Ireland, Scotland, Asia including The Philippines, Japan and South Korea.
