Helen is one of Finland’s largest energy companies, based in Helsinki. The company traces its roots to 1909 and is owned by the City of Helsinki. Its core business covers electricity production and sales, district heating, district cooling, electricity distribution and related customer services.
Helen’s geographic footprint is national in electricity retail: it sells electricity contracts across Finland. Its heating and cooling services are concentrated in Helsinki, where the company plays a central role in the city’s energy system. Through its network arm, Helen Electricity Network Ltd, the group distributes power to more than 430,000 customers in the capital region. Helen says its electricity network is highly reliable, with 96% of lines underground and an average outage time of around 30 minutes every ten years for a Helsinki resident.
The company’s activities combine infrastructure and retail services. Alongside standard electricity contracts, it offers district heating and district cooling, solar energy products and digital customer tools. A key service is Oma Helen, a digital platform and mobile app that lets customers follow consumption data, check prices, manage contracts and view billing information, in some cases down to hourly data. Helen also promotes e-billing and offers renewable or emission-free electricity options as add-ons.
A notable feature of Helen’s profile is its focus on customer-facing energy data and self-service. The company’s online services are designed to make energy use easier to track and manage, while its heating and cooling systems remain deeply tied to Helsinki’s urban infrastructure.
