What TSK Medio Ambiente does
TSK is a Spanish-headquartered global EPC contractor specializing in the energy transition and industrial decarbonization, founded in 1986 in Gijón (Asturias) and now listed on BME (Bolsa de Madrid) under ticker TSK. The company delivers turnkey engineering, procurement, and construction services across solar (photovoltaic and concentrated solar power), wind, biomass, hydroelectric, waste-to-energy, geothermal, hybrid generation, long-duration energy storage, hydrogen, combined-cycle gas, electrical infrastructure, water treatment, industrial plants, mining/material handling, and data center engineering. Core proprietary assets include the SKAL-ET parabolic trough collector (acquired with German subsidiary Flagsol in December 2013) and joint-developed Liquid Air Energy Storage and molten-salt electrical Thermal Energy Storage technologies (partner Highview Power). The portfolio is supported by a wholly-owned material-handling subsidiary (PHB Weserhütte) with its own radar-based warehouse automation product (PARVAMAP 3D).
TSK generates revenue primarily through one-time EPC contracts for large energy and infrastructure projects, supplemented by post-construction operations and maintenance (O&M) services (e.g., 6-year O&M at the Shagaya complex) and standalone engineering services. Customers are large enterprise utilities, independent power producers, sovereign offtakers, and government agencies — including EDF, Masdar, ACWA Power, AES, CFE, KISR, Globeleq, Fermí America, and OPC Energy — with whom TSK often forms consortia with local partners and OEMs such as Siemens Energy and GE Vernova. Project economics are bespoke and not publicly disclosed; contract sizes range from tens to several hundred million euros (e.g., Shagaya €362M; Tel Aviv combined cycle ~$1B; June 2026 multi-project package above $500M). International activity accounts for over 96% of sales across 30+ countries and four continents, with a cumulative reference base exceeding 25,000 MW across renewable, conventional, hybrid, and storage technologies.

TSK Medio Ambiente competitors and assessment
Company assessmentDirect peers
- SENER: Spanish engineering and technology group active in renewable energy (CSP, solar thermal, wind), power, and industrial infrastructure. Comparable to TSK in energy transition EPC and proprietary technology development.
- Abengoa: Historically a major Spanish EPC contractor for renewable energy (especially CSP), transmission, and water infrastructure. Was a direct competitor to TSK in solar thermal EPC before restructuring; provides legacy comparability for TSK's Flagsol-derived CSP business.
- Cobra Instalaciones y Servicios: Spanish EPC company (part of ACS Group) executing energy and infrastructure projects globally. Comparable to TSK in renewable and conventional power plant EPC, electrical infrastructure, and consortium-based delivery model.
- Fluor Corporation: Global EPC contractor for energy, urban solutions, and mission solutions. Comparable to TSK in large-scale power generation EPC, including renewable and conventional projects, with similar consortium and turnkey delivery approaches.
- Elecnor: Spanish infrastructure and energy EPC contractor with international operations. Highly comparable to TSK in renewable generation, electrical infrastructure, and turnkey project delivery for utilities and industrial clients.
- Técnicas Reunidas: Spanish EPC contractor for energy, oil & gas, and industrial infrastructure. Highly comparable to TSK given similar business model, international project focus, and energy transition portfolio.
Broad incumbents
- GE Vernova: Global energy equipment and services company with focus on power generation, grid solutions, and renewable energy. Comparable to TSK as a major equipment supplier (turbines) and broader incumbent in the EPC + technology space.
- Acciona Energía: Spanish renewable energy IPP and infrastructure developer with EPC capabilities. Comparable to TSK in renewable energy focus and Spanish origin, but operates more as an asset owner/operator than pure EPC contractor.
- Siemens Energy: Global energy technology and EPC provider with portfolio spanning turbines, generators, transmission, and renewable solutions. Comparable to TSK as a partner on combined cycle and CSP projects, and broader incumbent in the same EPC space.
Others
- Masdar: UAE-based renewable energy developer and IPP, frequent client/partner of TSK (e.g., Noor Midelt consortium). Not a direct competitor but a key counterpart in the renewable energy EPC ecosystem where TSK operates.
