TEPROELEC SL

What TEPROELEC SL does

TEPROELEC SL is a Spanish specialized electrical infrastructure contractor founded in October 1996 and headquartered in San Agustín del Guadalix, Madrid. The company delivers medium and high-voltage electrical installations with capabilities extending to substations up to 132kV, including GIS (Gas-Insulated Switchgear) and hybrid configurations, alongside underground and aerial power line construction, transformation centers, and industrial and commercial installations. Its service portfolio also encompasses preventive and corrective maintenance, project management, and legalization and regulatory commissioning. The firm combines in-house engineering (architects, delineants), specialized electrical installers, and project management functions to execute turnkey electrical infrastructure projects for enterprise clients, with reported cumulative track record of over 100 km of MV lines and over 400 km of LV lines installed across 28+ years of operation.

The company's commercial focus spans five customer segments: data center operators, industrial facilities, tertiary and commercial clients, residential developers, and public organisms. The only publicly named reference customer is ADIF (Spanish railway infrastructure administrator); data center operators, distribution companies, industrial facilities, and commercial centers are referenced by category rather than by logo. The business operates on a project-based, contract-driven revenue model, with each engagement typically involving multi-month execution cycles for substations, MV/HV cable runs, or transformation center deployments. Geographic operations cover multiple Spanish autonomous communities including Madrid, Valencia, Castilla y León, Castilla-La Mancha, and Andalucía.

TEPROELEC operates as a privately held company with no external investors, no disclosed funding rounds, and no M&A activity on record. The firm employs approximately 14 staff and follows a direct enterprise field-sales go-to-market model with technical pre-sales engineering embedded in the bid process. There is no indication of recurring SaaS, platform, or subscription-based revenue; the entire revenue base is project-driven and concentrated in HV/MV electrical infrastructure delivery.
