What eoltech does

Eoltech is an independent French consulting firm founded in 2002 and headquartered in Toulouse, specializing in wind and solar resource assessment for the renewable-energy finance value chain. The firm operates as a third-party expert and explicitly does not participate in project development, positioning itself as a trusted counterparty for banks, investors, and developers that require independent yield validation to make projects bankable. Its service portfolio covers pre-construction and post-construction yield estimation for wind and solar photovoltaic projects, the proprietary irec index for ongoing production benchmarking, technical support such as wind measurement campaign monitoring, Lidar calibration, performance diagnosis, and wake impact evaluation, plus WINDEX and EVEOL training programs co-developed with Metrol cabinet. Notable customer logos include Total Energies, EDF Energies Nouvelles, Engie Green, RWE, Allianz, BKW, Valorem, Enertrag, VSB, IWB, Kallista, and H2air, with explicit testimonial recognition that the firm is "recognized by banks and investors." Since inception, the firm has analyzed 18 GW across 850 projects and validated the irec index on 200+ operating wind farms. Operating geographies are concentrated in France with active extension into Germany and broader European engagement via WindEurope conference participation.

The technical foundation rests on proprietary methodologies for wind measurement campaigns, long-term correlation, and uncertainty analysis, rather than on disclosed AI/ML systems. The irec index, launched in 2011, is presented as an independent energy indicator system with stated ±5% uncertainty when operational data quality is satisfactory, and it underpins both ongoing production benchmarking and research publications on European wind resource variability. The combination of methodological intellectual property and 200+ farm operating dataset constitutes the firm's primary defensible asset, alongside the structural requirement for independence imposed by project financiers.

Eoltech monetizes primarily through project-based professional services engagements for yield assessment, supplemented by subscription-based access to irec index data and professional training delivered via the Metrol partnership. Pricing is not publicly disclosed and is scoped per project. Go-to-market is sales-led and direct, leveraging industry association membership (France Energie Eolienne), WindEurope conference presence, and research publications for visibility, with no intermediary or channel partner structure in place. The firm is privately held with a registered capital of €17,050, no institutional investors, and no parent company disclosed in the source data.

Core offering

Eoltech is an independent French consulting firm that provides wind and solar resource assessment services. Its core offerings include pre-construction and post-construction yield assessments for wind and photovoltaic projects, proprietary independent energy indices (irec index) for asset production monitoring, and technical support services such as wind measurement campaign monitoring, Lidar calibration, performance diagnosis, and wake impact evaluation. The firm operates as a trusted third party for project financing by deliberately not participating in project development.

Product overview

Eoltech is an independent consulting firm offering wind and solar resource assessment services. The portfolio includes four core offerings: (1) Wind Energy Yield Assessment for estimating wind project production capacity at pre or post construction stages; (2) Solar Energy Yield Assessment for estimating solar PV project production; (3) IREC Index - proprietary energy indicators developed in-house for monitoring wind and solar asset production; and (4) Technical Support services including wind measurement campaign monitoring, Lidar calibration, performance diagnosis, and wake impact evaluation. The company operates as a third-party independent expert, providing services free from conflict of interests to support wind and solar project financing.

Direct peers

• 3E: Belgian renewable energy consultancy offering wind/solar yield assessments, energy yield analytics, and technical due diligence. Comparable in offering independent yield studies and asset performance monitoring to the same developer/lender customer base.
• Natural Power: UK-based independent consultancy providing wind and solar resource assessment, ecological, and technical advisory services to developers, lenders, and asset managers. Closely comparable to Eoltech's niche as an independent third party supporting renewable project financing and operations.
• Vortex (Vortex FDC): Spain/France-based specialist in wind and solar resource measurement, forecasting, and resource assessment. Comparable as a direct competitor offering pre-construction yield studies, operational performance analysis, and independent energy indices, with similar niche focus on European wind markets.
• Meteotest: Swiss specialist firm offering wind and solar resource assessment, measurement campaigns, and energy yield studies. Closely comparable to Eoltech as a niche European wind/solar consultancy serving project developers and lenders.

Broad incumbents

• Bureau Veritas (Renewables): Global testing, inspection and certification company with a renewables practice spanning wind/solar technical due diligence and yield benchmarking. Overlaps with Eoltech's bankability-oriented consulting, though delivered through a much larger, multi-vertical firm.
• Wood (SgurrEnergy): Wood acquired SgurrEnergy and operates a global renewables advisory covering wind resource assessment and forecasting. Comparable in its focus on wind yield analytics and bankability studies, but with the scale and geographic reach of a large engineering firm.
• UL (Renewable Energy / formerly DEWI): UL acquired DEWI and operates a substantial wind energy consulting practice covering resource assessment, bankability, and operational due diligence. Overlaps directly with Eoltech's wind yield and measurement services, but is embedded within a much broader global testing/certification portfolio.
• COWI (Renewables): Large European engineering consultancy with a dedicated wind and solar advisory business covering resource assessment and owner's engineering. Comparable because it competes with Eoltech on yield assessments for European wind and solar projects, while also providing broader EPC-level services.
• AWS Truepower / UL Renewables measurement arm: Resource assessment and forecasting firm integrated into UL's renewables practice. Comparable to Eoltech on wind measurement campaigns, long-term correlation, and operational performance analytics, with broader parent capabilities.
• DNV (Energy Systems): Global assurance and certification giant with a large Energy Systems practice covering wind/solar resource assessment, bankability studies, and technical due diligence. Comparable because it offers the same independent third-party yield and lender advisory that Eoltech provides, but at much greater scale and breadth across geographies.
