IRU WTE high and medium voltage systemsPeterburi tee 105, Maardu, Harjumaa

The work involved the design and construction of the WTE plant’s 110 kV connection to Iru substation, and the delivery and implementation of a 110/10 kV 27.5 MW step-up transformer. In addition, 10 kV switchgear with seven bays, three transformers for the plant’s own use and the strong and weak-current connections between all equipment, including the plant’s generator, were designed, delivered and implemented. Ensuring compatibility of Iru’s new and old power plant proved a novel and complicated task.
