The commissioning of thelargest ORC system in Europe of 17.5 MWe in the Velika Ciglena geothermal power plant, Croatia, was completed by Turboden for the Turkish customer Geoen – MB Holding, in December 2018. The Velika Ciglena project exploits steam and hot water at 170°C to produce electricity to feed the local power grid.
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. Velika Ciglena project, with the 17.5 MW ORC turbine, in 2016 received the Best Innovation Award for its innovative design by Mitsubishi Heavy Industries (5 stage, low rpm, and proprietary design).
Mr. Paolo Bertuzzi, Turboden CEO, comments: “First of all, I want to thank all Turboden employees who took part of this new success and also Geoen – MB Holding team for the close cooperation during the development phases of this project. The strong commitment of Turboden in realizing dependable and efficient geothermal solutions has been confirmed by the implementation of the nominal test in a short time.”
