New substation to Kalasatama
Helen Sähköverkko will build a substation in Kalasatama to strengthen electricity distribution in nearby areas and to improve the security of electricity supply. The city is developing in Kalasatama, Sörnäistenniemi and Sompasaari, and electricity consumption in these areas is increasing. In addition to building a substation, a new underground distribution network will also be built in the area.
The substation will be built along the street area planned as an extension of Vilhovuorenkatu. In terms of the city’s landscape, the area commands a key location in the immediate vicinity of a valuable cultural environment, and this has been taken into account in the substation architecture. In the final stage, a graffiti fence will be built around the substation, and the appearance of the building will be enhanced with high-standard concrete and metal structures.
The substation construction will launch in April 2016 and the building will be completed in February 2017. After that, the process equipment installations and distribution network cabling will be started. The substation will be inaugurated in autumn 2017.
Helen Sähköverkko spends about EUR 40 million in investment each year to maintain the capital’s top-class security of supply. The average length of a power cut experienced by a Helsinki resident is 30 minutes every ten years.
