In its final report of installations last year, German wind energy institute DEWI states that 1070 new turbines were installed in Germany in 1995, amounting to 505.291 MW of rated capacity. This was 32.4% more turbines than installed during 1994 and 69.5% more generating capacity. A slightly lower tally for the year is recorded by Münster University's wind energy research group. It reports a total of 1035 turbines installed, 25.5% more than in the previous year, amounting to 494.7 MW in new capacity, 61.4% greater than 1994's increase. The university group, however, does not take prototypes into account or turbines installed for a limited period. Neither does it include grid connected turbines rated at less than 10 kW. According to DEWI, Germany was home to 3655 turbines by the end of 1995, 41.4% more than at the end of 1994. Installed wind capacity was 1136.517 MW, an 80% increase. The university group puts the tally at 3,579 turbines, a 40.7% increase amounting to 1126.9 MW, up 78.3% on 1994. The group also reports that gross sales in the wind sector increased by 52.8% in 1995 to DEM 1.23 billion. At the same time wind plant got cheaper: investment per MW installed, including all infrastructure construction, fell by 10.7% to DEM 2.5 million/MW. In comparison, a 1600 MW lignite power station in Germany costs DEM 5 billion, or DEM 3 million/MW. However it will operate at base load for around 7000 hours a year, while wind plant in Germany operate for 2000-2200 full load hours a year. Electricity generation from wind turbines in the group's data base amounted to 1.8 billion kWh representing a significant increase of 91.5%.
