What ESI - Engineering & Services Italy S.r.l. does

ESI - Engineering & Services Italy S.r.l. is a privately held Italian engineering services firm specializing in the repair, overhaul, and commissioning of medium-large electric motors and generators. Founded in its current corporate form in 2013 by Marco Boledi — whose career in the sector traces back to ASEA SERVICE in 1983 and the creation of ABB's first Service Manager role in 1988 — the company operates from a workshop in Rottofreno (Piacenza province) and delivers services both on-site at customer plants and in-shop. The company's core offerings include reverse engineering and component manufacturing, stator and rotor rewinding for DC and AC machines, dynamic balancing, thermal treatment, AVR configuration and replacement, and turnkey generator upgrades. Specialized capabilities cover hydro (up to 60 MW / 40 tons), thermal, and biomass power generation, as well as Ex-classified medium-voltage motors and waste-to-energy infrastructure.

The firm is differentiated by its workshop equipment: a large thermal oven (3.5 m × 6 m × 5 m) capable of treating the largest industrial motors, a 15-ton CEMB dynamic balancing machine (also used for third-party work), and a test bench with remote access installed in 2024 for horizontal and vertical rotating machines. On-site operations are supported by a portable instrumentation suite covering laser alignment, vibration analysis, network analysis, and portable excitation. ESI holds ISO 9001 and ISO 45001 certifications valid through November 2027 and maintains Approved Service Partner status with four major OEMs: WEG, Partzsch, Wolong, and Nidec/Leroy Somer (the latter relationship spanning over 25 years).

ESI serves enterprise clients across three verticals — power generation (hydroelectric, thermoelectric, biomass, ORC, combined cycle), industry (cement, metal, chemical/petrochemical, pharmaceutical, food, paper), and infrastructure (marine, water, harbours, waste-to-energy) — primarily in Italy with selective operations abroad in Europe. Revenue is generated through custom, project-based professional services contracts, with on-site field sales as the primary go-to-market motion. The company operates with 9 employees and has not raised external funding, reflecting its owner-operated, capability-led model rather than a venture-backed scale strategy.
