Offshore wind power set to reach the US; onshore wind in the US, Kenya and Brazil
The first utility-scale offshore wind farm in the US could become a reality following the signing of a contract between Siemens and the US Cape Wind for a farm off the north-east coast of the country.
Siemens will supply Cape Wind with 130 3.6 MW offshore wind turbines, an offshore electric service platform and a long-term service agreement. The 470 MW Cape Wind project is planned for the north-east coast, 20 km offshore of Nantucket, at Horseshoe Shoal in the Nantucket Sound. Installation and commissioning is planned for 2016. The US is a nascent area for offshore wind, with other areas under consideration for farms off the Atlantic coast and in the Gulf of Mexico.
Moving onshore in the US, where the wind industry is well established, five different wind farms are to be built in Iowa which together mark the largest single order for onshore wind turbines to date – a total of 448 turbines with a combined capacity of 1,050 MW. MidAmerican Energy has placed the order for the 2.3 MW Siemens turbines. In 2012, around 24% of total power generation in the state was provided by wind power. Elsewhere in the US, Vestas has received a series of orders for farms in Texas, alongside other locations, with a combined total of 830 MW of turbines.
Meanwhile, in Brazil, two large wind farms which together make a capacity of 400 MW are to be built in the state of Piauí in the north-east of the country. The 136 Alstom ‘ECO’ turbines are to be delivered between 2015 and 2017 for the Caldeirão Grande I and II wind farms.
Finally, in Kenya, 38 GE 1.6 MW wind turbines are to be installed to make the Kinangop wind farm. The farm will be developed by Aeolus Kenya and constructed by Iberdrola Engineering. It will be one of the largest wind power generation projects to be built to date in sub-Saharan Africa. The 61 MW wind farm will be constructed alongside Nairobi Ring, a large-scale grid upgrade for the Kenya Electricity Transmission utility including a high-voltage network, four new substations and the extension of the city’s largest existing substation. GE will train local technicians and provide technical advisory support for connecting the wind farm to the grid.
