- WIND'S PACE QUICKENS
- IN GERMANY
-
- German wind development is continuing its rapid growth through 1992
- and new capacity additions now rival those of any other country in
- the world, including Denmark.
-
- According to the German Wind Energy Institute (DEWI) in
- Wilhelmshaven, Germany's current installed capacity is 147 MW, up
- from about 110 MW at the end of 1991. By the end of 1992 total
- capacity will reach 170 MW, the Institute said.
-
- The 60-MW increase during the year will development in the U.S.,
- where only 10 MW will be installed this year, and match that of
- nearby Denmark, where new additions average about 50-60 MW per
- year. More significantly, the pace of wind construction in Germany
- is increasing. New additions totalled only about 15 MW in 1989,
- rising to 40 MW in 1990 and 50 MW in 1991.
-
- Statistics on the growth of the German wind industry are contained
- in the August issue of the Institute's magazine. The Institute,
- which is wholly supported by the state government of Niedersachsen,
- also reports that total generation should reach 275 million kWh
- this year.
-
- Two-thirds of the expected power production will come from machines
- with individual capacity ratings greater than 200 kW, even though
- turbines above that level account for only 30% of the country's 964
- wind systems. In contrast, small machines (less than 80 kW),
- comprise 47% of the total yet produce only 10% of the generation.
- According to the DEWI report, wind turbines up to 80 kW in capacity
- should generate about 1,310 kWh/kW of installed capacity; turbines
- from 80-200 kW, 1,750 kWh/kW; and turbines over 200 kW, 2,189
- kWh/kW.
-
- Generation of 2,000 kWh/kW is representative of the performance of
- a well-sited wind plant in California. Better-performing turbines
- both in California and on the West Cost of Denmark's Jutland
- peninsula can produce up to 3,000 kWh/kW of installed capacity.
- However, average performance both in California and in Denmark
- typically falls below 2,000 kWh/kW.
-
- The coastal laendler (states) of Niedersachsen, Schleswig-Holstein,
- and Mecklenburg-Vorpommern dominate German wind development with
- 47.8 MW, 73.8 MW, and 3.5 MW installed, respectively.
- Surprisingly, there is nearly 10 MW installed in the densely
- populated interior state of Nordrhein-Westfalen. Growth in the
- former East German state of Mecklenburg-Vorpommern has been
- particularly rapid, since it has occurred only since the country's
- reunification.
-
- The average size of new turbines has now reached about 195 kW, said
- the Institute report -- more than double that in 1988, when average
- capacity of new turbines was less than 100 kW. According to Anton
- Keuper, author of the report, the number of new machines less than
- 16 meters (52 feet) in diameter has fallen from 100% of the market
- in 1986 to only 20% today. Mid-size machines, ranging from 16
- meters to 45 meters (148 feet) in diameter, now dominate the German
- market. Keuper said Dutch manufacturer Lagerweij's 18-meter (59-
- foot), 80-kW turbine continues to sell well in Germany, but its
- contribution to total capacity is swamped by the larger turbines.
- Machines in the 22-meter to 32-meter (72-foot to 105-foot) range
- now dominate with 60% of the market.
-
- German manufacturer Enercon accounts for 26.7% of total installed
- capacity, followed by HSW, another German firm. Danish
- manufacturers Vestas (13.6%) and Bonus (6.4%) account for much of
- the remainder. Denmark's Micon and Nordtank and Germany's Tacke
- each account for slightly less than 6% of the market's capacity.

- ===============================
-
- The American Wind Energy Association (AWEA) has authorized me to offer
- an electronic edition of its newsletter, _Wind Energy Weekly_, from
- which the above article is excerpted, at no cost.
-
- For those of you who have not previously seen excerpts from back issues
- on Usenet or Bitnet, the _Weekly_ reports on the outlook for renewable
- energy, energy-related environmental issues, and renewable energy
- legislation in addition to wind industry trade news. The electronic
- edition normally runs about 10kb in length.
-
- If you would like a free electronic subscription, send me an e-mail
- request. Please include information on your position, organization,
- and reason for interest in the publication.
-
- If the _Weekly_ is not quite for you, please pass this message on to
- someone else you think might be interested. Thanks.
