Helen Oy

Helen Oy is a Finnish energy company based in Helsinki. It is associated with the earlier name Helsingin Energia and operates under the Helen name. The company serves households and other customers with electricity and energy-related services. Its current consumer website presents electricity contracts and tools for selecting and managing a contract, including options with fixed terms and a market-linked price structure. The company’s offering extends beyond electricity retail. Helen’s website refers to district heating, cooling and charging services, and it promotes tools for managing electricity use and heating costs. Its customer-facing products include electricity contracts with different pricing arrangements; customers can also select renewable-energy or nuclear-power origin options for their electricity, as described on the company’s website. Helen is owned by the City of Helsinki and is active in Finland. Its business is rooted in the Finnish capital’s municipal energy services, while its current website presents it as a customer-oriented energy company. The supplied homepage highlights household electricity customers and online contract services. It does not provide detailed information about current executives, corporate financials, or the company’s full geographic reach, so those details are not stated here.

Helen Oy’s corporate identity is tied to Helsinki’s municipal energy services and to the former name Helsingin Energia. The company is commonly associated with an energy undertaking established by the City of Helsinki in 1909. It subsequently operated as Helsingin Energia before adopting the Helen name. The evidence provided for this dossier does not document the detailed sequence or dates of those corporate changes, so the history here does not assign unsupported dates to the renaming or to particular reorganizations. Under the Helen name, the company presents itself as a Finnish energy and electricity company. Its present customer-facing activity includes electricity contracts for households, with products that vary in contract duration and pricing structure. The company’s homepage describes fixed-term contracts, a product combining fixed-price and market-linked pricing, and a spot-price contract. It also offers customers options to select renewable-energy or nuclear-power origin for their electricity, as described on the site. Helen’s service scope also includes district heating and cooling, as well as charging-related services. Its website highlights customer support across electricity, heating, cooling and charging, and promotes digital tools for contract selection and customer service. These services connect the company’s historical municipal-energy role with its current retail and customer-service presence. The City of Helsinki is the company’s owner. Helen is active in Finland and maintains its customer-facing web presence at helen.fi. The supplied homepage includes a claim that Helen was the most popular electricity company chosen by Finnish households according to EPSI Rating 2025; that is a company website claim and is not independently assessed here. The available source does not establish current leadership, detailed corporate milestones, or the full extent of Helen’s activities beyond the services described above.
