Wind project costs and turbine prices falling reveals DEWI study

Wind project costs in Germany fell by 7% and turbine prices were reduced by 9% between 1998 and 2001, according to the Deutsches Windenergie Institut (DEWI). It has studied around 400 German wind projects and found that project costs fell from EUR 520/MWh to EUR 480/MWh over a four year period, while turbine prices dropped by EUR 37 to EUR 375/MWh. DEWI arrives at its results by dividing total cost by annual energy generation in megawatt hours and using a standardised reference wind energy location for comparison of all projects. The fall in costs, in part, was due to a trend towards larger wind station projects, says DEWI. Turbine prices fell as manufacturers improved their products and increased series production, says study co-author Carsten Ender. Average turbine price over the four years (adjusted for inflation) was EUR 390/MWh per year while the remaining project costs came to an average EUR 116/MWh per year. Of the balance-of-plant costs (those other than the turbine), network connection is the largest single cost at 36%, followed by the foundation at 22%. Project development costs account for 9% and site development 7%. Other miscellaneous costs -- mainly those for dismantling the turbine at the end of its lifetime -- comprise 26%.
