Wind energy husum trade fair Full house at Vestas: with its new 3 MW V112 turbine, the Danish manufacturer presented an all-round system for locations with low to medium wind speeds.

Until then, nuclear power is to 128 Sun & Wind Energy 11/2010 step in and bridge the technology gap. The associat- ed extension of the operating times for nuclear pow- er plants, however, will also cement the monopoly position of the energy giants E.ON, Vattenfall, EnBW and RWE, a fact which naturally weighs heavily on the mood of the wind branch. There are many who fear for the domestic market. The scenarios developed by the commissioned institutes assume an increase in the installed capacity in Germany to 36.4 GW by 2050 (currently 26.3 GW): “The concept illustrates the priv- ileged treatment given to the big energy suppliers. Fully amortised base-load power stations are not compatible with decentralised renewable energy sources, and we are not partners of the nuclear pow- er industry. If our capacity expansion continues at the present rate, then we will already have met the gov- ernment targets by 2015. Thereafter, wind energy in Germany would effectively be discontinued,” com- plains Hermann Albers, President of the German Wind Energy Association (BWE).

Another sharp dip can be expected in Spain, where shore wind farm outside Europe at Donghai Bridge Photo: Torsten Thomas input tariffs have been reduced retrospectively by 35 % for at least 30 months. With just 800 MW, France will similarly fall well short of the envisaged 1,100 MW, and has furthermore introduced new environ- mental legislation with stricter approval procedures. The German export quota fell from 83 % (2007) to 75 % in 2009. Alongside, the domestic market shrank by 17.8 % in the first half of 2010, compared to the same period last year. The number one in the world is once more China, with new installations totalling 13.8 GW. It must be remembered, on the other hand, that the Chinese market, where 200 GW are assumed for installation by 2020, remains reserved for domestic manufacturers. In Eastern Europe, it is the devaluation of the local currencies which is putting dampers on the project developers. The overall result of this dwin- dling demand is pressure on the balance sheets and turbine prices of most manufacturers. The talk on the exhibition floor was that wind turbines are being sold well below the usual margins, and even German mar- ket leader Enercon is said to be lowering its prices.
