ENERTIS SOLAR

What ENERTIS SOLAR does

Enertis Solar, operating commercially as Enertis Applus+, is a global independent consulting and engineering firm headquartered in Madrid, Spain, founded in 2006. The firm specializes in technical advisory, engineering, quality assurance/quality control, testing and optimization, and energy storage solutions for solar PV, wind, BESS, and (more recently) green hydrogen projects, supported by three proprietary data science tools—A-PAA, TESSA, and the Smart PV Inspection Tool—and accredited fixed and mobile laboratories. As of available data, the firm employs 375+ consultants and engineers and has advised on 900+ GW of renewable energy projects, 8,000+ energy storage projects, and 150+ GWh of storage capacity across 65+ countries.

The firm operates a sales-led, professional-services model, engaging directly with developers, owners, financial entities, equity investors, and contractors on a project-by-project basis. Recent mandates include technical advisory for Excelsior Energy Capital's three Texas-based BESS projects (500 MW / 1,433 MWh) and for Matrix Renewables' acquisition of the Eccles and Kilmarnock BESS projects in Scotland (1 GW / 2 GWh). Pricing is not publicly disclosed; engagements appear to be negotiated per project, consistent with bespoke advisory and engineering work. Customer reach spans horizontal segments, with no single logo disclosed as a dominant revenue contributor within the visible data.

Enertis is associated with the Applus+ group through its commercial name and appears to operate as the renewables-focused business unit of that larger testing, inspection, and certification platform. The firm pursues growth through geographic expansion (notably the United States and United Kingdom for BESS), vertical diversification (green hydrogen), and thought leadership (PV module market intelligence, BESS supply-contract analysis, wind repowering advisory). Founders Iñaki Herrero Arregui (Co-founder and US Country Manager) and Amadeo Hernandez (Founder and Head of Business Development) are the named principals; no venture funding rounds, ownership structure details, or consolidated financial disclosures are present in the available source material.
