Energetika Ljubljana

What Energetika Ljubljana does

Energetika Ljubljana d.o.o. is the municipally-owned public energy utility of the City of Ljubljana, Slovenia, wholly owned through Javni Holding Ljubljana. It operates Slovenia's largest district heating and natural gas distribution networks, serving approximately 61,000 heat customers and 43,000 gas customers respectively, and covering 81% of apartments in the Municipality of Ljubljana (MOL) via more than 1,600 km of pipeline infrastructure equivalent in length to Ljubljana–London. The company is also Slovenia's largest cogeneration (CHP) producer at the TE-TOL thermal power plant, and with the 2025 commissioning of the PPE-TOL gas-steam unit its annual electricity output doubled to approximately 800 GWh — roughly 8% of national production — while reducing coal consumption by 70%.

The business model is fundamentally regulated: tariffs for heat, gas, and electricity are set under a methodology approved by Slovenia's Energy Agency, with revenue generated through recurring monthly subscription billing against metered consumption. Energetika Ljubljana also runs accredited testing laboratories for heat meters and gas measurement equipment, CNG refueling stations (including Slovenia's first public CNG site), an online customer portal ('Moj račun'), and a fleet of drones for infrastructure inspection. Customer segments split between residential households (the primary segment across heat and gas) and business customers — the latter particularly concentrated in electricity, where ~2,000 business connection points represent 90% of retail electricity business volume — plus wholesale electricity buyers sourced via periodic auctions.

Strategic direction is anchored in decarbonization: the new PPE-TOL gas-steam unit, the November 2025 launch of wood-chip co-firing on Block 3, the planned ~€100 million reconstruction of Boiler 1 to biomass (target 2027/2028, €30M EU co-financed), the EU-funded SENERGY NETS virtual heating plant/demand-response platform, the GrEn4Tran hydrogen refueling station, and a €5.5 million hydrogen/PV charging park. The 2014 merger of TE-TOL into Energetika Ljubljana unified heat, power, and gas operations under director Samo Lozej, and a 2025–2029 gasification plan for adjacent Grosuplje Municipality signals continued franchise expansion.
