- Riblet structures bring up to three percent more yield
- Europe-wide sales and retrofitting of turbines by Omega-Tools GmbH
Energiekontor AG, a pioneer of renewable energies since 1990 and listed in the SDAX of the German Stock Exchange, is gradually equipping its wind turbines with Novaflex BladeUp together with the international maintenance company Omega-Tools GmbH and the Coatings division of BASF, making them more efficient. With its microscopic line structures, the functional film ensures a noticeable increase in the yield of wind turbines. The riblets reduce the formation of unfavorable air turbulence on the blade surface, so that a larger proportion of the wind can be used to generate electricity. In a measurement campaign that has been running for about a year, an increase in performance of up to three percent was determined; For this purpose, BASF Novaflex BladeUp was installed on a 1.3-megawatt SWT 1,300 (formerly AN Bonus) system in Ilsede, Lower Saxony.
“We are impressed by the significant increase in power yield with Novaflex BladeUp. It is all the more important that we implement this option promptly for our systems and thus make a contribution to the energy transition,” says Carsten Schwarz, member of the Executive Board of Energiekontor AG. The company has placed an initial order with Omega-Tools GmbH to equip wind turbines of the tested type with the BASF film and intends to include other types of systems. In the long term, Energiekontor AG wants to equip all available turbines – its own and those owned by the company – with Novaflex BladeUp.
For the professional laying of the foils, BASF worked closely with the Wind division of Omega-Tools GmbH. “Subsequent application of the functional film to existing wind turbines can be done without long downtimes of the system and can be carried out for every model,” says Olaf Dostalek, Managing Director of Omega-Tools GmbH, which takes over the European market with his company -wide use of Novaflex BladeUp the turbines of Energiekontor AG, and who acts as a contact and sales partner for this technology in the market.
BASF is also interested in extending Novaflex BladeUp to turbines and blades from other manufacturers and in other power classes. “An integration into the manufacturing processes of the rotor blade manufacturers would also be possible, so that new wind turbines can directly generate a higher electricity yield,” says Jörg Lenz, head of the Beyond Paint Solutions business unit at BASF.
