What Gen-i does

GEN-I, trgovanje in prodaja električne energije, d.o.o. is a privately-held Slovenian integrated energy company headquartered in Krško that trades and supplies electricity and natural gas across 27 countries and 26 trading markets. Founded in 2004 and co-owned equally by state-owned GEN Energija d.o.o. and GEN-EL Naložbe d.o.o., the company operates a 24/7 algorithmic wholesale trading desk supported by over 100 analysts and 200+ trading partners, while running Slovenia's largest retail electricity supply business with 25% market share and 24.6% household share (fourth consecutive year of household segment leadership in 2024). In 2024 the company traded 295 TWh of commodities (versus 127.4 TWh in 2020), had a 2019 revenue base of 2.2 billion EUR, and reported 15.4 million EUR net profit in 2020.

The company's product portfolio spans electricity and natural gas supply (since January 2021, 100% CO2-free for all customers), solar power plant installation and management via the GEN-I Sonce subsidiary (10,000+ micro installations completed), battery energy storage system (BESS) optimization, e-mobility solutions, smart self-supply systems, and energy-sharing communities. Distribution is multi-channel: field sales for large enterprises, inside sales via a customer service line, and self-service digital portals (Moj GEN-I for residential and Moj GEN-I B2B for business customers). The company's newest revenue streams come from BESS asset optimization and trading partnerships - including a five-year exclusive optimization contract for a 127 MW/254 MWh facility in Romania with R.Power (signed February 2026) and a parallel five-year partnership with Sunotec to manage BESS facilities in Bulgaria (announced November 2025) - alongside the February 2026 launch of GEN-I Trading North America LLC in Houston, Texas.

GEN-I earns revenue through recurring monthly subscriptions for retail electricity and gas, transaction-based fees from wholesale trading (295 TWh volume in 2024), hardware sales from solar installations, and managed services plus profit-share arrangements for BESS asset optimization. The company reported revenue of 2.2 billion EUR in 2019 and has been actively issuing commercial paper and bonds (totalling 97 million EUR across 2018, 2019 and 2024) to fund working capital, while pursuing international expansion to support continued trading volume growth above 130% over the 2020-2024 period.

Recent moves7 records

Expansion highlights6 records

Direct peers

• Petrol: Slovenia's other dominant energy retailer, supplying electricity, natural gas, and petroleum products to households and businesses in Slovenia and the wider Balkans. Comparable customer base, product mix, and Slovenian market overlap make it the closest domestic peer.
• HEP: Croatian state-controlled integrated utility supplying electricity and gas across Croatia and the region. Comparable regional scope in Southeast Europe and similar state-ownership structure position HEP as a direct regional peer.
• Verbund: Austrian integrated energy company with large hydropower generation, wholesale trading, and B2B/B2C supply. Directly comparable on renewable-supply positioning, hydroelectric green tariff (similar to 100% Voda), and Central European trading footprint.
• Statkraft: Norwegian state-owned generator and Europe's largest renewable energy producer, active across European wholesale markets. Comparable state ownership, renewable supply focus, and algorithmic-trading style market participation.
• Axpo: Swiss integrated energy company combining generation, trading, and customer supply across Europe. Highly comparable business mix - algorithmic trading, renewable supply, and C&I focus - making it one of the closest analogues by size and strategy.

Broad incumbents

• CEZ Group: Czech Republic's largest energy group with electricity generation, trading, and supply across Central Europe. Comparable regional energy-trading exposure and renewable ambitions; larger and more diversified than GEN-I.
• E.ON: Germany-based European energy incumbent operating networks, retail supply, and energy solutions across multiple countries. Overlaps with GEN-I in retail electricity/gas supply and decentralized energy solutions but at much larger scale and broader scope.
• Enel: Italian-headquartered global energy incumbent with retail supply and renewable generation across Europe and the Americas. Comparable on renewable supply, green tariffs, and B2C digital platforms, but at vastly greater scale and geographic breadth.

Emerging players

• R.Power: Polish renewable energy developer and BESS operator partnering with GEN-I on the 127 MW/254 MWh Scornicesti asset. Comparable in BESS optimization ambitions and emerging CEE market presence, though on the developer/owner side rather than aggregator.
• Sunotec: Bulgarian/German EPC and BESS developer building facilities that GEN-I operates under five-year optimization deals. Comparable on BESS deployment in Southeast Europe and a peer in GEN-I's distributed-asset aggregation model.
