Ormazabal designs and supplies transformer substation as complete solution for a gas power plant

The Freital thermal power plant in Saxony supplies electricity to 6,000 German households. Where 12 boilers once provided thermal energy to an adjacent residential complex, two state-of-the-art combined heat and power (CHP) plants will now generate electricity with low emissions. At Ormazabal, we provided a complete transformer substation that enables connection to the public distribution grid. From engineering to delivery management, everything was carried out by a single source for our client, the electricity company Freitaler Stadtwerke (FSW).

The transformer substation has a surface area of 3.3 by 8.5 meters. It features a 3,150 kVA power transformer, which steps up the voltage from 10 kV to 20 kV for the Freitaler Stadtwerke medium-voltage network. The facility also includes an auxiliary services transformer, a low-voltage switchboard, and two remote control lines with their respective metering cabinets.

Ormazabal’s GA-GAE series cubicles are customized according to the client’s specifications. These units have integrated intelligent electronic protection and control devices that meet the requirements of the distribution network operator and ensure efficient management of the power generation plant: load decoupling, unwanted network configurations, real-time fault detection, and more. Thanks to this built-in intelligent technology, the operator can detect faults in real time and respond more quickly remotely.
