A comprehensive service and maintenance contract is also included in the conditional order. The final investment decision is expected to be made in the first quarter of 2021.
A total of 100 SG 14-222 DD turbines are planned to be installed. The project is located 195 km off the northeast coast of the U.K., on the shallow area of the central North Sea known as Dogger Bank. Each turbine will have a capacity of 14 MW and feature a rotor diameter of 222 meters using 108-meter Siemens Gamesa IntegralBlades.
At 1.4 GW, Sofia is the largest project in innogy’s current development portfolio. The 593 km2 offshore wind park will be roughly the same size as the Isle of Man. Its scale and size offer economic opportunities for the U.K. with potential supply chain benefits, infrastructure and associated jobs and contracts.
“We’re delighted that innogy has shown its confidence in our new machines and proven its commitment to creating a clean future with us now,” says Andreas Nauen, CEO of Siemens Gamesa.
“As an economic recovery around the globe safely and slowly begins, we’re confident that offshore wind power will strongly contribute to providing jobs and energy stability at attractive prices,” he adds.
The Sofia project continues an offshore wind partnership with innogy SE that began with Greater Gabbard, fully commissioned in 2013. Recently, Siemens Gamesa announced the firm order from innogy SE to supply the turbines for the 342 MW Kaskasi offshore wind power plant, located 35 km north of the island of Helgoland in the German North Sea.
The order comes directly after the U.K. saw a record-breaking period of more than 60 days’ coal-free energy provided to the national grid. This development will build upon the progress made by renewable energy in 2019, where the U.K. saw record levels of energy consumption provided by renewables and saw record-low prices for clean energy, dipping to just £39.50 per MWh.
The SG 14-222 incorporates the technology of the Siemens Gamesa Direct Drive offshore wind turbine platform. The reliable technology found in this global product offers stable operation and high availability while minimizing associated costs and risks. Each 108-meter IntegralBlade is cast in one piece using patented Siemens Gamesa blade technologies. The turbine’s massive 39,000 m2 swept area allows the SG 14-222 DD to increase annual energy production by more than 25% compared to the SG 11.0-200 DD offshore wind turbine.
This project takes the total conditional order backlog for the new SG 14-222 DD platform to 4.3 GW, following additional conditional orders recently announced in Taiwan and the U.S.
