The Blue Circle and its partner ACEN have completed the 40MW second phase of the Mui Ne wind farm in Binh Thuan province, south Vietnam.
The project features eight 5MW turbines with rotor diameters of 158 metres.
They are the first turbines to use blades in two pieces assembled on site, the developers said.
Construction was completed after only eight months with over 450 construction staff involved.
Mui Ne has a total expansion potential of up to 170MW.
he project’s estimated cost is around $70m, which is financed by debt and equity, and has qualified for the wind feed-in-tariff of 8.5 US cents per kilowatt-hour.
The Blue Circle will manage operations through an asset management services contract.
CEN international group head Patrice Clausse said: “We are delighted by the completion of phase 2 of the Mui Ne Project, and the overall progress made in expanding our renewables presence in Vietnam.
“We are thankful to our long-standing partners at The Blue Circle for seeing this project through amidst the pandemic, and we are encouraged that ACEN’s other partnerships across Vietnam will likewise bring to fruition more renewable energy projects in the country.”
The Blue Circle chief executive Olivier Duguet said: “We are very pleased to have been able to build, connect and reach commercial operations of this second phase of our Mui Ne site.
2021 has been undeniably a record year for the expansion of wind power in Vietnam and we are proud to have contributed with this project.”
The Blue Circle chief operating officer Herve Grillot said: “This two-pieces blade technology is a game-changer for onshore sites as it will allow larger capacity machines, lowering our cost of energy and enhancing competitiveness of wind energy.
“I am proud of our team for managing to achieve the project construction in time while facing exceptional constraints during a global pandemic.”
