Since 1996 wind turbines production and industrial wind power station construction have been carried on within the frames of the Complex program of the wind power station construction in Ukraine approved by The Decree of Cabinet of Ministers of Ukraine No.137 dated February 3, 1997. The financing of the Complex program of wind power station construction in Ukraine is performed from the specialized fund of the state budget (‘Wind power energy fund’).
General supervision and control of the program implementation is carried out by the Interdepartmental coordinating board comprising representatives of the Ministry of industrial policy, Ministry of fuel industry, National committee of electric power control, State water supply committee, Ministry of Defense, National aerospace agency, National enterprise “Energorynok”, National Academy of Science and Verkhovna Rada of Ukraine.
Development of wind power engineering is under the direct patronage of President of Ukraine.
Equipment and serial production of blades and nacelles of any complexity can be produced according to customer’s performance specification.
The ESTA enterprise repairs blades of wind turbines of any complexity.

USW 56-100 WIND TURBINE
ESTA carries on large-scale manufacture of 8 meter glass-fiber reinforced blades and nacelles for USW 56-100 industrial wind turbines of 107,5 kilowatt power rating, that has been produced in Ukraine since 1995 under the license of KENETECH Windpower, Inc (USA).
Production cycle of USW 56-100 comprises more than 30 enterprises.
The assembly is carried out at the State enterprise “PO Yuzhny machine-construction factory named after A.M. Makarov ” (Dnepropetrovsk).
By now over 1000 blades and 700 nacelles have been manufactured.
WBM-100 blades for the wind turbine USW 56-100
New blade WBM-100 is developed for wind turbine USW-100 with an advanced fastener assembly.
Blades of new type differ high reliability: the fastening method allows to avoid the problems inherent in an old design.
The blade tip has got the new, more pointed form that is conducive to decreasing of noise level of the working turbine.
The blade basis is made wider that makes windmill start more facilitated.
More than 20 sets of blades were turned out.
Since 2009 they successfully work as a part of installations on Saksky, Tarhankutsky, Novoazovsky and East Crimean wind power stations.
