Swedish energy company Vattenfall has placed an order with Siemens Gamesa for the supply of nearly 1GW of wind turbines for three upcoming offshore wind farms.

These wind farms include the Kriegers Flak in the Baltic Sea and Vesterhav North and Vesterhav South  in the North Sea. The total value of the order is €1.7bn and the installed capacity will be 955MW for the three wind farms put together.

In total, the company plans to invest over €2.7bn in Danish energy transition, adding 1.4GW new offshore wind capacity by 2022.

Vattenfall Wind Head and Executive Group Management member Gunnar Groebler said: “The deal is a further proof point of Vattenfall’s firm commitment towards a fossil free future and climate smarter living.

“The investment in this state-of-the-art technology for our modern wind farms, contributes significantly to our goal of building more renewable energy according to our strategy.”

The three wind farms will produce enough clean energy to be supplied to one million Danish homes. Vattenfall had won the tenders to build the wind farms last year, with the lowest tender quotation.

For the Kriegers Flak and Vesterhav North and Vesterhav South wind farms, Vattenfall had quoted a tender price of 0.050 EUR/kWh and 0.061 EUR/kWh, respectively.

The deal will include aspects such as design, manufacturing, installation, commissioning, testing and service of the turbines. As per the company, by bringing the wind turbine orders for the three wind farms under one umbrella can reduce the cost and benefit Danish energy consumers.

As per the order, Siemens Gamesa will supply 113 of 8MW turbines in total, out of which 72 turbines will be installed at Kriegers Flak and the remaining 41 turbines will be installed at Vesterhav Syd and Nord offshore wind farms.

Kriegers Flak has a capacity of 605MW, while Vesterhav North and Vesterhav South will have a capacity of 180 MW and 170MW respectively.

Siemens Gamesa stated that it will be supplying its new SG 8.0-167 DD or direct drive turbines. This turbine from the company has a rotor diameter of 167m and its B82 blades are claimed to provide an 18% greater swept area and up to 20% higher annual energy production than its predecessor SWT-7.0-154.

Siemens Gamesa Offshore CEO Andreas Nauen said: "We are pleased that Vattenfall has selected Siemens Gamesa for these projects. The advanced model of our proven direct drive offshore wind turbine platform and our advanced services will leverage the energy output of these lighthouse projects and help to move offshore wind into the energy mainstream in Europe."
