The new electricity substation completed at Viikinmäki ensures excellent security or supply for electricity distribution in Helsinki. The investment is also in preparation for the increasing power consumption in the city centre. Viikinmäki is an important hub in terms of reliable electricity distribution.
The new substation is in the immediate vicinity of Lahdenväylä, and the station is recognisable by the yellow landscape portal, which is now known as Viikin Keltakoipi [Yellow Legs of Viikki]. The name came about from a customer competition, which received more than 750 suggestions for names.
Helen Sähköverkko inaugurated the new Viikinmäki 110-kilovolt substation on Wednesday 20 May 2015. The completely modernised substation with its switchgear is built in a compact form, making its space requirement considerably smaller than the previous open switchyard.
The steel construction organisation Teräsrakenneyhdistys awarded the Viikinmäki landscape portal and station building the 2014 steel structure prize. The prize is a prestigious recognition among architecture and construction professionals.
The building works of the Viikinmäki substation began in spring 2013, and the equipment installations got under way in spring 2014. The cabling and overhead line works were completed during autumn 2014. The investment costs of the Viikinmäki substation are about EUR 14 million.
