How to read this comparison →Inventory revision: 2026-09-29. Each record retains its own source snapshot. “Operational” is a source classification, not a live status or service contract.
How much wind capacity do companies report servicing? These two annual reports describe their fleets at 31 December 2025. Capacity under service is a more useful activity measure than the number of service products advertised.
Wind capacity under service · More than 56,000 turbines · Reporting date: .
Vestas Annual Report 2025, p. 35Nominal wind capacity under service worldwide · 13,868 turbines · Reporting date: .
Nordex Annual Integrated Report 2025, p. 31Company-reported snapshots, not live contract counts or a complete industry ranking. Other companies are unmeasured here, not zero. Definitions and contract scopes can differ. These global figures stay separate from the filtered atlas records below and do not identify a site's current contractor. 1 GW = 1,000 MW.

Explore companies like Vestas, Siemens Gamesa and solar equipment suppliers. These company-described offerings are not endorsements or evidence of an active contract at a listed site. Equipment warranties and whole-plant O&M are different services. Reviewed 2026-09-30.
Vestas describes turbine maintenance, component repair, fleet optimisation and digital services. A turbine's manufacturer field does not identify its present maintenance contractor.
Nordex describes field and remote support, turbine maintenance, repairs, component replacement and upgrades. Service availability does not establish a contract at any listed farm.
Siemens Gamesa describes maintenance for onshore, offshore and multibrand turbines, alongside diagnostics, spares, repair and asset optimisation. Historical Siemens supplier names remain separate in the atlas.
GE Vernova describes wind service agreements, remote monitoring, maintenance, parts, performance upgrades and major-component repair. Its installed turbine base is not the same measure as capacity under service contracts.
ENERCON describes maintenance, inspections, repairs and technical operating optimisation for its turbines and wind farms, with full-service and modular contract options. A historical manufacturer entry does not identify today's contract.
First Solar's official FAQ identifies it as a thin-film module manufacturer and explicitly says it does not operate or maintain solar projects. Module supply must remain separate from a park's O&M provider.
Trinasolar's customer portal supports module enquiries, warranty claims and authenticity checks, with support for mounting systems and storage equipment. Warranty support does not establish an O&M contract for a whole park.
Sungrow's service page provides regional support, warranty claims and product documentation for utility customers and distributors. Equipment support does not establish that Sungrow operates an entire solar park.
Its UK service page describes third-party solar and storage O&M, including monitoring, inspections, electrical services and module cleaning. Historical planning applicants are retained under their original source names.
Cypress Creek describes development, construction, asset ownership and operations, including O&M for third-party owners. Older inventory ownership entries do not confirm the current owner or service provider.
This explorer uses the atlas’s wind and solar inventory. Missing company fields are excluded from comparisons, not assigned to an invented owner. Placeholder labels such as “Unknown” and “Private Developer” are not treated as company names. Coverage is particularly incomplete where sources omit ownership.
Only whitespace and letter case are normalised. Joint-owner names remain as supplied. Semicolon-separated manufacturer lists are split into supplier associations. A record appears once per company and selected role; a farm with multiple manufacturers can appear for each supplier. Its whole-farm rating cannot be attributed to one supplier, so associated capacities overlap and must not be added across companies.
Counts combine the source’s own record units, including turbines, units and sites. Rankings are by those records, not by distinct wind farms or solar parks. Capacity ratings can also mix AC/DC and site/unit definitions. Ownership shares, mergers, current contracts and generation are not inferred.
UK DESNZ REPD supplies operator/applicant fields and operational classifications. Danish Energy Agency supplies historical turbine manufacturers. Norway NVE supplies wind-farm ownership and turbine suppliers. WRI’s historical database contributes many owner fields; these do not establish current operations.
