MB Holding was founded in 1968 in the southeast part of Turkey, and operates in many fields including energy, building construction, construction of greenhouses and textiles. MB Holding is the first pioneering geothermal developer that implemented a binary plant in Turkey.
The region of Velika Ciglena is situated in Bjelovar subdepression, the north east of Croatia. The reservoir was discovered in 1990 by INA-Naftaplin, during an underground exploration for oil. The oil was never found, instead, a promising potential for geothermal energy was discovered.
The Velika Ciglena project, will exploit steam and hot water at 170°C to produce electricity to feed the local power grid. Turboden designed and manufactured a unique single turbine of 16 MW electrical power. The ORC turbogenerator with a 5-stage axial turbine, optimizes the performance with a rotation speed of 1500 rpm. Thanks to the flexibility of the ORC system, the plant will grant a highly efficient behavior in all the operation conditions.
