Vestas has developed a customised solution for a 50 MW intertidal project in Bac Lieu Province, Vietnam for the local EPC construction company Bac Phuong.
The intertidal project site is covered in water at high tide and some of the turbines will be uncovered at low tide.
Vestas said it will supervise the installation of the turbines in shallow waters close to shore in the Mekong Delta region to exploit the potential of the region’s wind conditions. The project includes a combination of V150-4.2 MW turbines in different power ratings with site-specific towers placed on reinforced onshore foundations that are raised above sea level.
The contract includes the supply and supervision of the installation of 13 V150-4.2 MW wind turbines with 10 turbines delivered in 3.8 MW and three turbines delivered in 4 MW operating modes to enhance energy production for the site’s specific wind conditions.
Vestas said it will equip each turbine with a converter, enhancing the wind park’s compliance with grid requirements.
Vestas did not reveal the financial details of the contract.
“This project demonstrates Vestas’ ability to develop wind energy solutions that unlock high wind sites in complex and challenging environments,” said Tommaso Rovatti Studihrad, sales director of Vestas Asia Pacific.
The project also includes a 10-year Active Output Management 5000 (AOM 5000) service agreement, designed to maximise energy production for the project, said William Gaillard, Sales Vice-President of Vestas Asia Pacific.
With a yield-based availability guarantee, Vestas will provide the customer with long-term business case certainty. Turbine installation is expected to be completed in the first quarter of 2021.
“With the FIT deadline in November 2021 it was critical for us to find a partner that would ensure a successful and timely project completion. With the technical support and supervision from Vestas during installation of the wind turbines, Dong Hai 1 will catch the finish line ahead of time,” said Mai Trong Thinh, chairman of Bac Phuong.
