What Elpro does

Elpro GmbH is a Berlin-headquartered electrical engineering, automation, and energy-supply specialist serving critical infrastructure operators across Germany. The company traces its operational lineage to 1926 (AEG Apparatewerke) and was restructured under its current ownership in 1997–1998; it operates from a 4,000 sqm manufacturing facility in Berlin-Marzahn supported by regional service offices in Leuna (East) and Essen (West). Its core offerings span three business areas: Energy Distribution & Infrastructure (110/15 kV traction power substations, DC switchgear for S-Bahn Berlin/Hamburg and tram networks, railway electrification), Process Industry (compressor station automation, gas storage facility control systems, pipeline and hydrogen infrastructure), and in-house Products & Manufacturing (custom switchgear cabinets, DC and low-voltage switchgear, drive systems).

The product portfolio combines proprietary hardware with AI-enabled software. Flagship hardware includes the SGBA2 protection and control unit — a modular IEC 61131-3 PLC device with dual processors, integrated data logger, and Modbus TCP/Profinet/IEC 61850 communication — alongside the GUW+ DC Substation architecture that integrates tram infrastructure with EV charging, battery storage, and regenerative braking. On the software side, EOS is an AI-based energy management platform that ingests real-time data from hundreds of sensors, applies pattern recognition and predictive analytics, and produces optimization recommendations used in substations, gas storage facilities, and a DLR-piloted high-temperature heat pump installation. The company also offers the tGUW, a transportable container-format rectifier substation that requires no special transport permits.

Revenue is generated through four mechanisms: project-based engineering services (planning, engineering, assembly, commissioning), proprietary hardware sales (1,000+ switchgear cabinets manufactured annually), EOS software licensing and configuration with long-term support, and recurring service contracts (24/7 on-call service, maintenance, spare parts, training). Customers are concentrated among large infrastructure operators — Deutsche Bahn (Q1 supplier, Top Supplier 2025, Schneider Electric-co-served S-Bahn projects), RWE (Epe H-Gas storage), Stadtwerke Leipzig (South CHP), MEGAL/OGE (Waidhaus/Wildenranna compressor stations), Vattenfall, ÜSTRA Hannover, and municipal operators (Kommunalservice Jena, Jenaer Nahverkehr). Go-to-market is direct enterprise field sales, secured via public tenders and negotiated long-term contracts; there is no reseller or distributor network and no disclosed international footprint beyond Germany. The company is privately held (owner-acquired in 1998), ISO 9001/14001/50001 and SCC certified, GDPR compliant, and assessed under EcoVadis for sustainability.
