What Onde S A does
ONDE S.A. is a Toruń-based, Warsaw Stock Exchange-listed renewable energy EPC contractor and developer, operating as a subsidiary within the ERBUD Capital Group. Founded in 2010, the company delivers engineering, procurement, and construction services for wind farms, photovoltaic farms, and battery energy storage systems, supplemented by in-house design (IDE Projekt), civil and road construction, and 5-year operation and maintenance contracts.

The business operates across four revenue streams: (1) professional-services EPC contracting secured through tenders and direct negotiations with renewable energy developers and investors; (2) a Develop-Sell-Build model under which ONDE acquires early-stage projects, develops them, and sells them bundled with construction contracts (proprietary portfolio exceeded 2 GW at turn of 2025/2026, with 387 MW holding grid connection conditions); (3) own asset operations, begun in 2025 with the 32 MW Lewałd PV farm (PLN 7.5 million partial-year revenue); and (4) recurring O&M services. Geographic footprint spans Poland, Lithuania, Germany, Romania, and Latvia, with wholly-owned subsidiaries ONDE GmbH and ONDE Romania. Customer roster includes Energa Green Development, R.Power, Polenergia, European Energy, Energix Polska, ENGIE, Axpo, and Nordex.

Onde S A competitors and assessment
Company assessmentBroad incumbents
- TAURON Polska Energia: Major Polish utility group with growing renewable energy investments including wind and solar, listed on the Warsaw Stock Exchange. Comparable as a large-scale Polish energy incumbent pursuing renewable buildouts similar to ONDE's customer base.
- ZE PAK: Polish energy company transitioning from lignite to renewable generation, including utility-scale solar and storage projects. Comparable as a Polish-based power sector incumbent undergoing a renewable transformation in which ONDE provides EPC services.
- ENGIE Polska: Polish subsidiary of French utility ENGIE, engaged in renewable generation and energy services. Comparable as a major international utility operating in Polish RES that intersects with ONDE both as a customer and as a competing developer of renewable assets.
- PGE Polska Grupa Energetyczna: Largest Polish utility and the country's biggest renewable energy builder. Operates a much broader portfolio across generation, distribution, and retail, and is both a potential competitor for EPC services and a major customer in the Polish market.
Direct peers
- European Energy: Danish renewable energy developer with significant operations in Poland spanning wind, solar, and storage. Competes directly with ONDE on Polish project development and EPC services, and is also a customer and partner.
- R.Power: Polish renewable energy developer specializing in utility-scale PV and BESS, including the 300MW/1,200MWh Dziegielewo and 250MW/1,000MWh Gdansk storage projects contracted to ONDE. Comparable as a BESS-led developer in the same Polish market.
- Energix Renewable Energies: Israeli renewable energy developer with significant Polish wind and solar operations. Competes with ONDE in Polish renewable development and EPC demand, and is also an ONDE customer and partner.
- BayWa r.e. German-headquartered renewable energy project developer and EPC service provider active across Europe. Operates a comparable full-lifecycle model spanning wind, solar, and storage project development, construction, and O&M, directly competing with ONDE in Central European markets.
- Polenergia: Polish energy group with significant onshore wind, solar, and emerging BESS activities, listed on the Warsaw Stock Exchange. Overlaps with ONDE in the Polish renewable EPC and development market and is also a customer of ONDE.
Others
- Nordex: German wind turbine manufacturer for whom ONDE GmbH performs turbine foundation construction contracts. Comparable as a core wind industry partner in ONDE's German market and an enabler of ONDE's wind EPC service line rather than a direct EPC competitor.
