In October 2021, the transformers that are the soul of Lumen Park Szolnok arrived at the electric substation. The equipment was transported by special trucks from Zagreb to Szolnok. The equipment was manufactured by Koncár, a world-renowned Croatian company, specifically tailored to the needs of the Szolnok Solar Park. The transformers were lifted into place by specially trained technicians using a prefabricated rail system and hydraulic jacks with centimetre precision.
At the Lumen Park’s Szolnok substation, two 120 per 20 kilovolt, 50 megavolt-ampere transformers will convert the direct current generated in the solar park into alternating current for the national grid, which will be fed into the MAVIR station in Szolnok.
By October 2021, contractors will have completed the construction of the buildings that will house the substation control systems. The three buildings – two twin buildings for the control of the two solar parks and a separate third building for the control of the output power – were fully completed by December 2021. The IT and power systems will then be installed in the buildings.
