ESELEC

What ESELEC does

ESELEC INGENIEROS S.L. is a Madrid-headquartered electrical engineering services firm founded in 1997 that specializes in the design, modernization, and electrical study of power generation plants across multiple technologies, including combined-cycle gas, cogeneration, biomass, hydroelectric, wind, solar photovoltaic, and high-voltage substations. The firm operates with 27 employees and reports project execution across 18+ countries on multiple continents, leveraging industry-standard power systems analysis software (DigSILENT Power Factory, ETAP, PSS/E) to deliver basic engineering, detailed engineering, owner engineering, supervision, feasibility studies, and grid code compliance work. Service lines extend into adjacent verticals including Oil & Gas electrical installations, industrial facilities, and water treatment/desalination plants, with retrofit and modernization services addressing aging generation fleet upgrades.

The business operates on a project-based professional services model with custom, quote-based pricing tailored to each client's specifications. ESELEC sells primarily through direct enterprise B2B engagement, targeting large electric utilities, small and medium independent power producers, construction firms, engineering companies, and specialized investment funds requiring technical due diligence. Go-to-market relies on direct sales via website contact forms, phone, and LinkedIn presence, with no public pricing tiers and no disclosed marketing-led demand generation. The firm has established an academic partnership with Universidad Politécnica de Madrid's Industrial Engineering School for joint training and research, and offers specialized training courses covering excitation systems, protection systems, switchgear, transformers, and ETAP software as a complementary recurring-revenue stream. No external funding, M&A activity, or institutional investors are disclosed in the available data.

• AFRY: European engineering consultancy (formerly Pöyry and ÅF) with a large Energy division covering thermal, hydro, and renewable generation design and grid studies — directly comparable in services and target clients to ESELEC, though at much larger scale.
• SENER: Spanish engineering and technology group with a dedicated Power, Oil & Gas line covering generation plant design, electrical systems, and grid connection studies — directly overlapping ESELEC's core offering.

Broad incumbents

• Worley: Global energy, chemicals, and resources engineering services firm with significant power-generation and grid engineering practices — competes with ESELEC on larger international generation and modernization mandates.
• COBRA (VINCI Group): Spanish-headquartered EPC and industrial services group within VINCI, executing power generation and grid projects worldwide — overlaps with ESELEC's customer base and technology scope but at a far larger scale and broader portfolio.
• Tractebel (ENGIE): Large European engineering consultancy under ENGIE offering power-generation design, electrical studies, and grid connection services across thermal and renewables — overlaps ESELEC's services but serves a much wider portfolio and larger clients.
• Técnicas Reunidas: Spanish EPC major for large power, oil & gas, and industrial projects — adjacent peer with electrical engineering capability embedded in much larger turnkey execution, competing for the same utility and IPP customers.

Regional players

• Burns & McDonnell: US-based engineering, architecture, and construction firm with strong power-generation, T&D, and protection-systems practices — directly comparable services but primarily serving North American clients rather than ESELEC's Spanish/European/LatAm markets.

Others

• Mott MacDonald: Global engineering, management, and development consultancy with an energy practice covering power generation and grid studies — comparable service line, though typically engaged at larger scale than ESELEC's boutique mandates.
