ATC-3

What ATC-3 does

ATC-3 S.L. is a privately-held Spanish consulting and training company headquartered in Sevilla (registered CIF B-41569781), founded in 2017 and operating since at least 2017 with a founding legal date of 2017 per company filings. The company's core offering centers on specialized professional training for the Spanish electrical power value chain — generation (nuclear, thermal, hydroelectric), transmission, distribution, and electrical installation/maintenance — alongside in-person training at client facilities and ATC-3's dedicated training academy in Salteras. ATC-3 is certified to deliver high-voltage live work training (distance and contact methods), photovoltaic installation, work-at-height, scaffolding, and occupational risk prevention programs compliant with Spanish regulations such as Real Decreto 2177/2004. The company holds ISO 9001 and ISO 14001 certifications.

ATC-3 monetizes primarily through multi-year enterprise B2B training contracts with the major Spanish energy and infrastructure operators: Redeia (Red Eléctrica de España), Enel Green Power/Endesa (5-year contract), Repsol Renovables (3-year contract), Grupo Naturgy/UFD, AENA (airports), Grupo Jesús Bárcenas, and Aquila Clean Energy (renewables). Named contracts typically cover defined theoretical-practical hour blocks (14 to 90 hours), with training delivered either on-site at client assets or at ATC-3's Salteras training center. A secondary revenue stream runs through European Social Fund co-financed public employment programs — Programa Operativo de Empleo Juvenil, España Emprende — delivered in partnership with Fundación EOI and Cámaras de Comercio, which extend ATC-3's reach into youth upskilling and SME workforce development. Consulting, grants advisory, and technical studies/project services round out the portfolio.

The company runs a proprietary online learning campus (campusonline.atc3.com) hosting more than 1,000 courses across electrical safety, occupational health, environmental management, renewable energy, digital skills, and soft skills, supplemented by a public course catalog portal (catalogocursos.atc3.com). Distribution is carried by direct enterprise field sales to large operators and by partnership channels for subsidized programs. Total disclosed employee headcount is 6, indicating a small core team with delivery leverage via subcontracted certified trainers. The company received two European Regional Development Fund (FEDER) grants in 2024 — PymeInnova and Pyme Cibersegura, channeled via the Cámara de Comercio de Sevilla — supporting innovation and cybersecurity initiatives but not venture capital. There is no evidence of M&A activity, external institutional investment, or international geographic expansion beyond Spain.
