What Helen does
Helen Oy is a Helsinki-based municipally-owned energy utility that supplies electricity to approximately 430,000 customers across the Helsinki metropolitan area and provides district heating to over 90% of Helsinki's properties through a 6,500 km distribution network. Founded in 1909 and organized as Helen Oy with wholly-owned subsidiaries including Helen Sähköverkko Oy (electricity distribution) and Helen Ydinvoima Oy (nuclear energy development), the company is undergoing an explicit energy transition targeting combustion-free production by 2040. Core operations span electricity retail (fixed-term, spot-price, and subscription contracts via Pörssisähkön and Perussähkö products), district heating (Kaukolämpö, including CO2-free Ekolämpö Kierto and renewable Ekolämpö Bio variants), district cooling for buildings and data centers, EV charging under the Helen Lataus brand, and rental solar panels from €5.46/month.
The technology stack combines physical infrastructure with applied AI: Helen operates the world's largest air-to-water heat pump plant at Patola (30 MW heating + 2x50 MW electric boilers, generating 500+ GWh/year and cutting CO2 by 56,000 tons annually), Europe's largest electric boiler plant with thermal accumulator at Hanasaari, and the Optimilämpö AI optimization system that reduces housing company heating costs by 4-5% via learning algorithms processing temperature, weather, and building data. The Kiinteistövahti property monitoring platform and Älykäs lämmönjakokeskus smart heat distribution centers provide continuous IoT data, while a Cognigy.AI-powered chatbot handles real-time customer service. Recent strategic moves include a €1-5 billion planned SMR investment, partnerships with Steady Energy and Fortum on small nuclear heat reactors, and integration of data center waste heat from Equinix, Telia, and Elisa into Helsinki's district heating network.
Revenue is generated through subscription-based and usage-based pricing across residential, business, and housing company segments, with the Oma Helen mobile and web platform serving as the unified customer interface. GTM is hybrid: self-serve digital channels (helen.fi, Oma Helen app, Yritys Helen business portal) for residential and SMB customers, plus dedicated account management for enterprises and housing companies. The company recently absorbed Väré through merger, expanding its customer base, and participates in the BalticSeaH2 cross-border hydrogen valley project (40 partners across 9 countries) and the 3H2 Helsinki Hydrogen Hub for clean hydrogen production integrated with synthetic protein (Solein) manufacturing.

Helen competitors and assessment
Company assessmentDirect peers
- Fortum: Fortum is the largest Finnish and Nordic utility, generating and supplying electricity and district heating across Finland, Sweden, and the Baltics. It is a direct peer because of overlapping electricity generation/distribution, district heating, and nuclear/SMR development — and is even a co-investor with Helen in the Steady Energy SMR pilot.
- Vattenfall: Vattenfall is the Swedish state-owned utility and one of Europe's largest district heating operators (e.g., Stockholm Exergi-equivalent operations), with significant heat-pump and electricity T&D activities. Highly comparable to Helen in integrated electricity + district heating business model in the Nordic region.
- Stockholm Exergi: Stockholm Exergi operates the district heating and cooling network for the Stockholm region and is investing heavily in heat pumps and bio-CCS to decarbonize. A direct functional peer for Helen's heat-pump and district-heating transition strategy.
Broad incumbents
- E.ON: E.ON is a major European integrated utility with extensive district heating operations (especially in Germany and Sweden) and energy networks. Comparable to Helen in T&D + heating but operates at much larger scale and broader geographic footprint.
- Veolia: Veolia is a global leader in district heating and cooling networks, particularly in Central and Eastern Europe. Comparable to Helen in district energy operations and decarbonization of urban heat, though Helen is far smaller and geographically concentrated.
- Engie: Engie is a global utility with significant district heating networks in France and Benelux, plus a strong pivot toward renewables and heat pumps. Comparable to Helen in heat-pump decarbonization and integrated energy services, but at vastly greater scale.
- Statkraft: Statkraft is the Norwegian state-owned power generator and Europe's largest renewable energy producer, active in hydro, wind, and solar. Comparable to Helen in renewable electricity generation and Nordic market participation, though Statkraft does not operate district heating networks.
- Ørsted: Ørsted is the Danish state-owned utility that has pivoted from fossil generation to offshore wind and green energy. Comparable to Helen in the broader Nordic utility peer group and renewable-energy transition, but not in district heating.
Regional players
- Tampereen Sähkölaitos: Tampereen Sähkölaitos is the municipal energy utility of Tampere, Finland, providing electricity, district heating, and related services. A direct comparable to Helen as a Finnish municipal multi-utility, though operating in a different geography.
- Turku Energia: Turku Energia is the municipal energy utility of Turku, Finland, supplying electricity and district heating in the Turku region. Comparable to Helen as a Finnish municipal utility with electricity and district heating portfolios, though smaller and serving a different city.
