After two years of construction, all components of the German offshore wind farm Bard Offshore 1 are now installed. In December 2010, the Bard Group reported that the first wind turbine had gone into operation; on 1 August 2013 they now announced that all 80 systems are installed and that 65 of them are already feeding electricity into the grid.

Vestas and Mitsubishi form a joint venture for offshore business

Vestas Wind Systems A/S and Mitsubishi Heavy Industries Ltd. are combining their offshore activities in a new joint venture. Vestas will bring know-how, personnel and orders into the partnership; Mitsubishi will begin by contributing € 100 million.

China's State Grid in talks to buy AES' US wind assets

The deal would give SGCC an 80 % controlling stake in AES' US wind power business, including wind energy assets totalling around 1.1 GW,. This was reported by Reuters, citing three unnamed sources. These assets are estimated to total approximately US$ 1.65 billion.

Stable EU market for offshore wind energy

A total of 235 wind turbines were erected in nine offshore wind farms in 2011. The turbines cost around € 2.4 billion. Nine further offshore wind farms are currently under construction. These projects alone will bring a further 2,375 MW online and increase the total capacity installed offshore by 62%.

The project received matched funding from the Cohesion Fund of the European Union. It represents a total investment of around € 57 million.

Nordex lowers turnover and earnings targets

Therefore, the turnover and earnings targets for 2011 have been lowered. For 2012, however, the company expects profitable growth. According to Nordex, the sovereign debt crisis in Europe and rising capital requirements imposed on commercial banks have made financing of wind farm projects more difficult.

Topping-out ceremony for Europe's highest wind turbine

In early 2012, after a few months of tests and calibrations, the Enercon E-70 should start producing 3 GWh of power per year. The logistical challenge was taken up by Martin Senn, founder of SwissWinds, and his team. They had to develop a special low-loader, the "millipede", to transport the 35-metre rotor blades up the winding mountain roads from Airolo in Tessin to the Nufenpass in Wallis.

Areva and Iberdrola plan offshore projects

The two companies recently signed a corresponding letter of intent according to which Areva will be the sole supplier of the offshore turbines, which Iberdrola will use to equip the wind farms. The French government plans to achieve an offshore capacity of 6,000 MW by 2020. The first tender period with 3,000 MW begins in July and consists of five zones along the French coast.

China: additional capacity of nearly 19 GW

The Chinese Renewable Energy Industries Association (CREIA) assumed in January, that turbines with a capacity of approx. 16 GW had been put up in 2010. According to the latest figures, however, the new installations amounted to 18.9 GW, so that the accumulated wind power capacity is now approx. 44.7 GW.

Small energy bundle from Southwest

This makes the 2.4 kW turbine the most efficient grid-coupled turbine in its class. At an average wind speed of 18 km/h (12 mph) the turbine can produce an average of 7400 kWh of electricity annually. This is equivalent to around 60% of the electricity requirement of an average US household. With the help of the internet, the owner of the turbine can monitor its electricity production.
