What Energy Solar Tech does

Energy Solar Tech, S.A. is a Madrid-headquartered energy technology company (founded 2020) that operates an integrated platform covering the full energy value chain: distributed generation (photovoltaic, wind, cogeneration, hydrogen, biogas, biomass), engineering and construction, centralized renewable generation assets, and modular manufacturing of e-houses and data centers. The company's core commercial model is Energy Outsourcing — multi-year contracts under which Energy Solar Tech assumes investment, regulatory, and technological risk for commercial and industrial clients in exchange for a guaranteed minimum energy cost. Customers span more than 1,050 entities, with roughly 40% drawn from IBEX-35 listed companies, and include EDP, Iberdrola, Enel Green Power, Naturgy, Siemens, Drylock Technologies, and Graphic Packaging.

The group is organized around four business lines — Distributed Generation, Engineering and Construction, Centralized Generation (own renewable assets including the 18 MW Valdelugo wind park), and Modular Manufacturing — supplemented by CNMC-regulated energy retail through subsidiary Enerfía, S.L. and energy engineering capabilities acquired via Sarpel in 2022. Technology differentiators include AI-enabled monitoring and integration of SCADA, BMS, and ERP systems for energy optimization, plus ISO 9001/14001/45001 and GHG Protocol certifications.

The company is publicly traded on BME Growth (since December 2022) and Euronext Growth Paris (since December 2025), with reported 2025 revenue of €81.2M and EBITDA of €11.1M. A share-for-share takeover bid by Spain's Greening was announced in May 2026 at a 41% premium, and a new manufacturing facility in León opened in March 2025 to scale e-house and modular data center output.

Core offering

Energy Solar Tech provides an end-to-end Energy Outsourcing service that manages a client's complete energy model — covering distributed generation (photovoltaic, mini-wind, cogeneration, hydrogen, biogas, biomass), engineering and construction of electrical infrastructure, centralized renewable generation assets (wind, photovoltaic, hydroelectric), and modular manufacturing of plug-and-play e-houses and data centers. The outsourcing model guarantees clients the lowest energy cost while eliminating their investment, regulatory, management and technological risks. Complementing this are regulated energy commercialization through subsidiary Enerfía, S.L. and energy purchase management services including PPA agreements and emission rights administration.

Product overview

Energy Solar Tech operates as a technology company providing comprehensive energy solutions through a platform of integrated services. The core offering is their Energy Outsourcing model, which is complemented by four operational divisions: Distributed Generation (photovoltaic, micro-wind, cogeneration, hydrogen, biogas, biomass), Engineering and Construction (industrial, utilities, energy efficiency, storage, electric vehicle infrastructure), Centralized Generation (wind farms, photovoltaic plants, hydroelectric, reversible plants), and Manufacturing (modular e-houses and data centers). The company also operates energy commercialization through subsidiary Enerfía, S.L. Together, these services enable clients to reduce energy costs without investment, regulatory, or technological risks.

Direct peers

• Greening: Greening is a Spanish solar EPC and distributed-generation company that launched the May 2026 takeover offer for Energy Solar Tech. It directly competes with EST in Spanish distributed generation and self-consumption installations, serving similar C&I clients. The impending merger would make Greening the most direct peer at the consolidated level.
• Solarpack (subsidiary of Equinor): Solarpack is a Spanish solar PV developer and EPC contractor historically focused on utility-scale and C&I projects in Iberia and Latin America. Now owned by Equinor, it competes with EST's centralized generation and distributed generation business, and shares the Spanish enterprise customer base.
• Audax Renovables: Audax Renovables is a Spanish energy retailer and renewable energy generator serving C&I clients with both energy supply and self-consumption solutions. Closely comparable to EST's combination of energy retail (via Enerfía) and distributed generation — including overlap in PPAs and 100% renewable offerings for industrial clients.
• Grenergy Renovables: Grenergy is a Spanish renewable energy developer listed on BME Growth/Continuo, focused on utility-scale solar and wind plus battery storage across Spain, LATAM, and the US. It competes with EST's centralized generation arm and shares a similar public-market listing profile in Madrid.
• Solaria Energía y Medioambiente: Solaria is a Spanish solar PV developer focused on utility-scale and distributed generation across Iberia. It directly overlaps with EST's distributed generation and centralized generation product lines, particularly for C&I and public-sector clients in Spain.
• TSK: TSK is a Spanish EPC contractor specializing in power plants, substations, and industrial electrical projects. It competes with EST's engineering and construction line of business and modular e-house offerings for industrial and energy sector clients.
• Capital Energy: Capital Energy is a Spanish vertically integrated renewable energy developer active in wind, solar, and storage across Iberia. It overlaps with EST's centralized generation development and long-term PPA-driven commercial offerings for industrial off-takers.

Broad incumbents

• Acciona Energía: Acciona Energía is a large global renewable energy operator with utility-scale wind, solar, and storage assets. As a broad incumbent it competes with EST's centralized generation and provides an analogue for how EST could scale, though it does not focus on the Spanish C&I outsourcing niche.
• Naturgy Energy Group: Naturgy is a major Spanish/Iberian multi-utility serving residential, commercial, and industrial customers with gas, electricity, and energy services. It competes with EST's energy retail subsidiary Enerfía and C&I outsourcing offerings, and is simultaneously a partner and customer of EST.

Emerging players

• Ingeteam: Ingeteam is a Spanish technology company specializing in power electronics, generators, and control systems for renewable energy projects. It is a partial competitor to EST's engineering and construction business and supplies equipment that EST integrates in its e-houses and substations.
