"Helen Sähköverkko Oy (Helen Electricity Network Ltd.)  - We distribute electricity to Helsinki residents. We have 375,000 customers in the capital region.

The length of a power outage experienced by a Helsinki resident is only 30 minutes every ten years on average. Our security of supply is therefore outstanding. The electricity network in Helsinki extends to almost 6,200 km, 96% of which runs in weatherproof underground cables. With our smart electricity meters, we measure the electricity consumption of homes in Helsinki by the hour. We strive to operate as a good neighbour in the urban space of Helsinki.

In the year 2015, the turnover was EUR 97.2 million. We spend about EUR 40 million in investment each year to upgrade and maintain the network.  With 100 employees Helen Electricity Network Ltd is a subsidiary of Helen Ltd and is owned by the city of Helsinki."
