New Tower 133-metre Hub Height Set to Increase Yield

The new hybrid tower

The new hybrid tower


Officially grid-connected and set to work this week in Germany is a new wind tower from ATS. The novel tower construction allows very high hub heights that may increase a turbine’s yield by 20% or more.

With its hub height of 133 meters, the system has an overall height of 180 meters.

„This is a great day for wind energy.” said Frans Brughuis, Managing Director of the tower construction specialist Advanced Tower Systems (ATS). “Now the pilot project can demonstrate the high cost-effectiveness and efficiency of the ATS concept,”

The system, one of the largest wind energy systems with hybrid tower in the world, is installed at Germany’s Windtest test field at Grevenbroich, near Cologne.

The lower section of the innovative tower consists of narrow concrete pre-fabricated parts (76.5 meters concrete from ATS), and the upper section of conventional steel components 55 meters steel (Siemens). Atop the tower is a Siemens SWP 2.3 megawatt nacelle with a 93 meter diameter rotor. With its hub height of 133 meters, the system has an overall height of 180 meters.

The tower was constructed and operated by ATS Projekt Grevenbroich GmbH, in which juwi Netzwerk GmbH & Co. KG, Mecal Projects GmbH, Hurks subsidiary HB Bau GmbH and Siemens Project Ventures (SPV) have equal shares.

ATS reports that the response within the industry has been correspondingly positive. „At international wind trade fairs such as the EWEC in Marseille and the Windpower in Chicago the ATS concept has already aroused great interest from project developers and turbine manufacturers as well as investors,” added ATS Sales Manager Johannes Bietz.

More than 20 ATS systems are being planned by the end of 2010.

Compared to the widely used hub height of 100 meters (328 feet), the ATS system achieves energy claims an additional yield of some 20 percent more. This is particularly important for inland locations with lower wind speeds. The higher outlay for the tower construction should be recouped in approximately four years, says the company, and the maintenance costs are very low.

REW Wind Technology Correspondent will be looking at this innovation and the issue of tall tower in more detail in Renewable Energy World magazine.

Suzlon: Un MW pe eolian costa 1 mil. €, mai putin cu 20%

Pretul total al unui megawatt (MW) instalat in centrale eoliene a scazut cu aproximativ 20% anul acesta fata de 2008, ajungand la circa 1 mil. euro, pe fondul crizei financiare, a declarat pentru Business Standard Peter Rosenberg, senior sales manager al companiei Suzlon Wind Energy, parte a grupului Suzlon, furnizorul numarul cinci mondial de turbine, prezent si pe piata locala.

“Pretul de piata pe un MW eolian a ajuns la circa 1 mil.euro, fata de 1,2-1,3 mil. euro in urma cu un an, scazand costul echipamentelor, al serviciilor sau cel cu instalarea. Si noi am redus pretul, in toata piata s-a intamplat acest lucru”, a spus oficialul. Compania a incheiat pana acum in Romania un singur contract de livrare turbine cu portughezii de la Martifer, pentru o capacitate de 60,9 MW, ce va fi instalata la Babadag (jud. Tulcea). Pentru a asigura service-ul echipamentelor si lucrarile de mentenanta, Suzlon si-a deschis anul trecut in noiembrie o reprezentanta locala, care va furniza servicii si pentru proiectele viitoare, posibil si pentru cele derulate in Bulgaria. De altfel, Suzlon se afla in discutii cu doua companii care vor sa dezvolte proiecte eoliene pe plan local cu o capacitate totala de circa 120 MW. Potrivit lui Rosenberg, una dintre tendintele pietei este ca dezvoltatorii sa mearga pe proiecte cu capacitati de pana la 6-10 MW, care sa fie extinse cand piata isi va reveni.

2008 saw revenue soar for wind turbine manufacturer Clipper Windpower

Clipper Windpower, a manufacturer of advanced wind turbines, has posted a soar in revenue for the year ended 31 December, 2008, reaching $737.3m compared to $23.8m the previous year.

The company attributed the growth to the 248 turbines it sold throughout 2008 compared to just nine in 2007. At the close of December, the company recorded its cash balance at $209m, compared to $114.4m at the close of 2007. Net loss for the year was $313.3m, compared to $192.5m loss in 2007.

In addition, the company ramped up its production rates, managing to manufacture 289 turbines across the year, which have a total output of 723MW. Clipper Windpower expects to deliver between 300 and 325 turbines in 2009.

Doug Pertz, Clipper’s CEO and president, said, ‘Clipper’s tremendous revenue growth in 2008 highlights our important transition from a technology development company to the delivery of industrial-scale production of the 2.5MW Liberty turbine. We are aggressively meeting the challenges presented by the current difficult market conditions, while ensuring we retain the flexibility to scale up the business when growth returns. The Obama Administration has set a goal of doubling US wind generating capacity within three years and has approved legislation to support technologies essential to accelerating wind deployment.’
