Turku Energia

What Turku Energia does

Turku Energia is a vertically integrated municipal energy utility headquartered in Turku, Finland, wholly owned by the City of Turku and operating since 1898. The company generates and distributes electricity, district heating, district cooling, and industrial steam, and sells related retail products and services under the Louna brand family (electricity contracts), Louna Solaris / Louna Solar (solar PV packages), Walle (home EV charging), EnergiaOnline (digital self-service portal), and Eturinki (customer benefits program). It serves three primary customer segments — households, businesses, and housing companies — with electricity contracts sold nationwide and district heating, cooling, and electricity distribution (via subsidiary Turku Energia Sähköverkot Oy) limited to the Turku, Kaarina, Raisio, and Naantali region.

The company's core technology stack comprises 2,700+ km of electricity distribution lines, 660 km of district heating pipeline, and local generation assets including the Naantali multi-fuel power plant, Oriketo bioheat centre, Kakola wastewater heat-recovery plant (~280 GWh/year equivalent to ~11,000 detached houses), the Biolaakso ammonia-heat-pump cooling centre, and the Naantali flue-gas condenser (~250 GWh/year). District heating was 95.2% renewable/biomass-based in 2025 with emissions of 11.0 kgCO2/MWh (down 65.2% year-on-year), and the company targets 100% renewable district heating and carbon-neutral production by 2029 in alignment with the City of Turku's Hiilineutraali Turku 2029 initiative.

Commercially, Turku Energia operates a hybrid go-to-market model: product-led growth for standardized residential offerings (electricity contracts, solar packages, EV chargers with transparent online pricing and the 24/7 EnergiaOnline portal) combined with sales-led account management for businesses and housing companies, supported by turnkey installation services and the Eturinki loyalty ecosystem with 60+ partner companies. Revenue is generated through recurring utility charges (electricity per kWh plus base fee, district heating energy charge plus capacity-based power fee with seasonal pricing), one-time equipment sales (solar, EV chargers, batteries), regulated network tariffs, and premium add-ons such as Alkuperätakuu origin guarantees (+1.26 to +2.18 EUR/MWh). Additional service lines include EnerKey energy management, portfolio management (Salkunhallintapalvelu), energy audits, and load-flexibility (Kulutusjousto) for business customers.
