Renewable Sources

Exploitation of renewable energy sources represents not only an imperative of every developed society, but also an obligation of preserving and protection of the nature for next generations. On the other hand, investments into development of new products inspire and spur competition capacities of each business entity.      

That was the reason why KONČAR – KET, supported by other companies belonging to the KONČAR Group, developed, designed, manufactured and put into operation wind turbines of 1MW and 2.5 MW resulting from its in-house research and development as early as in 2005 wishing to launch a new Croatian product on the market. Wind turbines were erected in Pometeno Brdo Wind Power Plant placed near the town of Split (having the total installed power of 17.5 MW). The Plant has been in full commercial operation since 2008, while it was extended in 2012.

During the last twenty years, development of the wind turbine technology has been aiming towards manufacture of wind turbines of as high powers as possible, with rotors having larger rotor diameters then ever, simple to produce, including usage of safer and cheaper materials, equipment that would have the life time of at least 20 years when maintained properly, satisfying all performances warrantied by the manufacturer supported by always present and guaranteed high availability.         

Taking into consideration all the required wind turbine characteristics, KONČAR engineers have designed, developed and manufactured wind turbines that are produced nowadays as a serial product in KONČAR Group factories and workshops in Zagreb.

Construction of wind power plants represents a complex engineering project starting with high demanding preparatory works, very careful selection of the equipment, manufacture of all the components supported by severe quality controls of each manufactured part, precise placing of each wind turbine at the site and various and comprehensive final tests and inspections. The project is not finished with the construction itself, but it keeps up with rendering of operation and maintenance services together with continuous monitoring and adjustment of electrical energy production.   

Majority of countries has already passed legal rules and regulations prescribing construction of renewable energy resource facilities including wind power plants. Motivating their construction, those countries take an active participation in environmental protection respecting its own legal obligation bound to the decrease of green-house gases accepted in international agreements worldwide.

Generation of electric energy from the force of the wind is constantly increasing and it is replacing other conventional manufacturers of the electric power using fossil fuels, slowly, but steadily. While costs per generation of a kWh of electric power generated from a plant using fossil fuels are constantly rising, partially due to a constant increase of power source prices, the cost of generation of a kWh of the electric power generated in a wind power plant is constantly decreasing thanks to the development of new technical solutions and decrease of operational and maintenance costs (O&M) of plants. Besides the already stated facts, the influence of wind turbines to the decrease of green-house gas emissions is worth mentioning supported by the fact that only one wind turbine of the power of 2.5 MW in operation, under the presumption of its operation during 2300 hours per year at the nominal power, can generate electric energy sufficient for the needs of 1500 households and decrease the CO2 emission by 4002 t.
