Suvilahti Substation, Helsinki, Finland

Helen Sähköverkko Oy is responsible for electricity transmission and distribution throughout almost the entire Helsinki region. The company is part of the Helen Group, a private utility group. The company’s Suvilahti substation had grown from being just an electrical substation to a multipurpose building housing a sea water pump station, a solar power plant and a data center. To increase the safety and reliability of the site’s expanded scope, the company sought an active fire protection solution whose installation would cause minimal disruption to the site’s diverse operations. Gas systems were ruled out, because they require expensive structural changes to the substation.
