A major merger in wind turbine manufacturing is just around the corner: Siemens Wind Power and the Spanish company Gamesa have announced binding agreements for merging the Siemens wind power business, including service, with Gamesa. The combined company will be based in Spain. Siemens will hold a 59% stake and Gamesa's shareholders will hold 41%.

The preparations took a year; finally at the end of May, the test rig known as the FVA nacelle was officially inaugurated at the RWTH Aachen. A joint project is currently in progress there to test the stresses on drive components of wind turbines at the Centre for Wind Power Drives (CWD).


Prysmian breaks voltage record

For the first time in the cable industry, the Prysmian Group achieved voltages of 700 and 600 kV in high-voltage DC transmission (HVDC). This means that the company achieves an energy transmission capacity increase of up to 15 percent and improved grid reliability. (Photo: Prysmian Group)

The Prysmian Group has announced two milestones in energy transmission: the company's new mass-impregnated 700 kV MI-PPL and the 600 kV cross-linked polyethylene cable systems (XLPE) for applications in high-voltage DC transmission (HVDC) field have been successfully tested and have also set new voltage records.

Gamesa has announced a new order from Elecnor for the expansion of the Maan wind farm in Jordan. The contract includes the addition of seven new G97-2.0 MW wind turbines with a total power of 14 MW.


Vertical transport record

If horizontal does not work, then do it vertically: Since the lower tower segment of a wind turbine in Denmark could not be transported in a horizontal position, the transport companies needed to come up with something special. They also broke a record while they were at it.


Major energy companies sign offshore wind declaration

Ahead of the Energy Council in Luxembourg on June 6, 2016, 11 energy companies signed a joint declaration stating that offshore wind can be fully competitive with coal and gas by 2025, achieving a cost of 80 €/MWh and below.

Wind energy is growing faster than any other type of energy generation in the USA. The American Wind Energy Association (AWEA) is clearly proud of the results achieved over the last five years: There was an installed capacity of almost 74 GW at the end of 2015. This is more than twice as much as there was five years ago.
