Erlangen, Germany, June 4, 2010 — RWE Innogy, Stadtwerke Munchen and Siemens have entered into a joint venture to build the offshore wind farm Gwynt y Mor (Welsh for “wind in the sea”).
RWE Innogy will hold a 60 percent stake in this joint venture, SWM 30 percent and Siemens 10 percent.
The total investment amounts to more than two billion Euros, including the grid connection to the coast. The investment will be divided between the partners accordingly.
Gwynt y Mor is to be built with an installed capacity of 576 MW in Liverpool Bay, around 18 kilometers off the North Wales coast.
Work will start towards the end of 2011 to erect the first foundations for a total of 160 wind turbines. All permits for the wind farm covering an area of 79 square kilometers have already been obtained. Siemens will supply, install and maintain the wind turbines, and provide the connection to the grid.
Prof. Fritz Vahrenholt, CEO of RWE Innogy, explains: “In 2008 we started making RWE greener. With an output of almost 580 MW and an annual saving in carbon production of around 1.7 million tonnes, Gwynt y Mor will contribute to this.
In its first phase of expansion, the wind farm is planned to generate electricity as early as 2013. The project is slated for completion in 2014.
From then onwards it is forecast to generate around 1,950 GW hours of electricity annually, enough to supply around 400,000 British households. The site is in a very favorable location: Liverpool Bay in North Wales is characterized by comparatively shallow water and very high wind speeds.
Siemens supplies wind turbines and is responsible for connection to the grid and maintenance of the wind farm. For this project Siemens Energy will receive the contract not only for supply, erection and maintenance of the wind turbines, but also for electrical connection of the Gwynt y Mor wind farm to the mainland.
The value of the contract for Siemens is around 1.2 billion Euros.
Siemens will supply and erect 160 wind power installations each with a capacity of 3.6 megawatts for the Gwynt y Mor project. Siemens will also be responsible for connecting the wind turbines to the grid, which entails the delivery of two turnkey offshore transformer platforms.
Using high-voltage sea cables, power will be transmitted to the Welsh town of St. Asaph, from where inland distribution will take place. Siemens will also be responsible for maintenance of the wind farm for five years, with the option of an extension for a further seven years.
