What Stoen Operator does
Stoen Operator Sp. z o.o. is a regulated electricity Distribution System Operator (OSD, Operator Sieci Dystrybucyjnej) that distributes electricity across the Warsaw metropolitan area and surrounding municipalities in Poland. The company operates a network of 17,000 km of power lines — including 330 km of 110 kV overhead lines, 203 km of 110 kV cable, 8,196 km of 15 kV cable, and 6,512 km of 0.4 kV cable — supported by 7,221 substations (1 at 220 kV, 45 at 110 kV, 7,175 at 15 kV). It serves 1,158,714 customers (2026) with a workforce of approximately 600 employees and recorded 2026 reliability metrics of SAIDI 34.51 minutes and SAIFI 0.76. Its technology stack includes 210,000 remote-read smart meters with Wireless M-Bus/P1 interfaces, an AI-powered digital twin of the distribution grid, drone-based computer-vision inspection of power lines, Distributed Temperature Sensing (DTS) on 110 kV cables, and AI-based anomaly detection and predictive maintenance for low-voltage equipment.
The business operates under an exclusive distribution license issued by the Polish Energy Regulatory Office (URE), which approves tariffs annually and governs network operation via the IRiESD (Instrukcja Ruchu i Eksploatacji Sieci Dystrybucyjnej). Revenue is generated primarily through regulated distribution tariffs — including quality, capacity, and grid-usage components — applied across differentiated tariff groups (A, B, C for business/industrial; G and R for residential), plus one-time connection fees, ancillary services (diagnostic measurements, design/construction approvals, emergency response), and EV-charging connection fees. Customer segments include residential households, commercial and industrial facilities, licensed energy trading companies (sprzedawcy energii) that resell electricity over the network, and power-generation facility owners connecting renewables, cogeneration, and storage assets. The company is a wholly-owned subsidiary of E.ON Group (previously operated as innogy Stoen Operator), led by President Robert Stelmaszczyk (since March 2007) and Management Board Member Wojciech Graczyk (since December 2025). Stoen Operator also participates in sector-wide initiatives, notably the 2022 URE Charter for Effective Transformation of Polish Distribution Networks co-signed with ENEA, ENERGA, PGE, and TAURON Dystrybucja.
