What company is Acciona?
Acciona, S.A., with Spanish tax identifier A08001851 and registered office at Avenida de la Gran Vía de Hortaleza, 3, Madrid, heads a Spanish infrastructure, energy and services group. This profile covers the consolidated group. The parent company, Acciona Energía and Nordex are separate entities: their figures are not interchangeable, although the latter two fall within Acciona’s consolidation scope. Sources: 2025 accounts: identity and activities; Official annual report archive.
The group combines asset construction and operation, renewable generation, water, services and wind-turbine manufacturing. Its 2025 sustainability report places its activity in more than 60 countries. Understanding prevention requires identifying the business, project and employer, rather than assigning a single construction or electricity activity to the entire organisation. This is an editorial interpretation of its operational diversity. Sources: 2025 accounts: identity and activities; International activity in 2025.
Origins and formation of the present group
Acciona took its present group form in 1997 through the combination of Entrecanales y Távora and Cubiertas y MZOV. Its roots are older: José Entrecanales Ibarra and Manuel Távora established Entrecanales y Távora on 11 March 1931; Cubiertas y Tejados had been incorporated in 1916, while MZOV originated in railway development. Thus, 1997 identifies the formation of the present group, rather than the beginning of every company brought into it. Sources: Acciona corporate history.
The corporate history moved from construction work towards a combination of infrastructure, concessions and renewable energy. Today’s diversification also includes Nordex’s wind-turbine industrial business. This evolution helps explain the coexistence of temporary construction work, ongoing maintenance, manufacturing and services within the group: these activities do not necessarily share the same exposures or training needs.

Shareholders, Acciona Energía and Nordex
At 31 December 2025, Tussen de Grachten B.V. held 29.02% of voting rights and Wit Europese Investering B.V. held 26.83%, according to the corporate governance report. Both companies channel holdings of descendants of José Entrecanales Ibarra. The report states that neither holding company is controlled by any single individual or legal entity. Describing Acciona as exclusively owned by its chair would therefore oversimplify the structure. Sources: Significant shareholders at 31 December 2025; Indirect family shareholdings.
The 2025 accounts place the interest in Acciona Energía at 91.11% at year-end. Nordex has been fully consolidated since Acciona obtained control in 2023 with a 47.08% holding. Accounting control does not always require ownership above 50%. These businesses contribute their activities to the consolidated group; their individual revenue should not be added again to Acciona’s reported revenue.

Who leads the company?
On review on 8 November 2026, José Manuel Entrecanales Domecq is listed as executive chair and Juan Ignacio Entrecanales Franco as executive vice-chair. These are the roles shown on the current board page. Current leadership is presented separately from the 2025 financial figures, so the date of a financial snapshot is not treated as the presumed date of every appointment.

Activities and business model
Acciona Energía develops and operates renewable generation; Infrastructure brings together construction, concessions, water and other services. Water includes desalination, treatment and water-cycle management. Nordex designs, manufactures and supplies wind turbines and provides maintenance. The group also reports property activities, fund management, urban and environmental services and other services. Acciona and Nordex are brands with different functions within this structure. Sources: 2025 accounts: identity and activities; Nordex control and consolidation.
The model combines contract and service revenue, sales of energy and equipment, and the operation of assets over extended periods. As a business interpretation, this creates prevention decisions at different stages: design and construction, commissioning, operation, intervention and maintenance. A division’s certification or result does not, by itself, describe conditions at every contract, factory or installation.

2025 figures and their meaning
The latest complete annual reporting year available is 2025, from 1 January to 31 December. Consolidated accounts under EU-adopted IFRS report net revenue of EUR20,236 million, compared with EUR19,190 million in 2024. Operating profit was EUR1,862 million and profit attributable to the parent was EUR803 million. Total profit for the year was EUR1,129 million, including EUR326 million attributable to non-controlling interests. These are different measures. Sources: Official annual report archive; 2025 consolidated income statement.
The average 2025 workforce was 68,502 full-time equivalents, compared with 66,021 in 2024. The calculation weights days worked and working-time commitments: it is not the number of individual people employed on the last day of the year. This distinction affects both company-size comparisons and attempts to relate workforce figures to accidents. The published injury rates use hours worked, rather than this average, as their denominator. Sources: 2025 consolidated average workforce; Workforce and full-time equivalent calculation; OHS results and rate definitions.
Prevention system and ISO 45001 scope
Acciona describes procedures to identify and assess risks associated with installations, activities, equipment, substances and particularly hazardous work, alongside corrective measures, training and worker consultation. The 2025 table reports health and safety management-system coverage of 100% of employees; coverage for non-employee workers is shown as unavailable. That percentage should not be extended to every person working in the value chain. Sources: Prevention and lessons learned in 2025; OHS results and rate definitions.
The ISO 45001 certification table reports 100% within a defined scope: business lines by country with more than 150 full-time equivalents, excluding temporary joint ventures. The report explains that certification is conducted by activity and, in some cases, by activity and country, and that some projects are too short to certify. System coverage and certification coverage are distinct concepts. Sources: ISO 45001 certification scope.
3D lessons, alarms and leadership
Among measures implemented in 2025, Acciona reports a lessons-learned library using 3D representations of significant accidents. It also documents an intelligent centre for alarm visualisation and management in its construction and concessions businesses in Brazil. These are concrete examples of information and prevention technology with a stated scope: they do not establish that the Brazilian centre operates worldwide or, by themselves, demonstrate fewer injuries. Sources: Prevention and lessons learned in 2025; Safety and health measures implemented in 2025.
Infrastructure introduced “5m HS Learning” to share knowledge and experience; the group describes Safety Leadership Training for supervisors and the “Diálogos de Seguridad” tool and indicator. Nordex reinforced its Life Saving Rules and conducted a global safety-perception survey in 2025. Acciona Energía implemented a plan addressing fatal and very serious accidents, including audits of operating assets and construction projects and leadership measures. The relevant business name should be retained when citing these initiatives. Sources: Safety and health measures implemented in 2025.
Suppliers and contractors
The report identifies supplier and subcontractor inspections and audits. Under enhanced approval of certain suppliers with high social risk, those classified as MACS must pass an audit and close every serious nonconformity before approval for contracting above EUR400,000. The aim of auditing 90% of these critical suppliers on the company’s own works is a management target; it does not mean that 90% of all contractors have passed an audit. Sources: Safety and health measures implemented in 2025; Supplier approval and subcontractor injury outcomes.
This coordination deserves specific attention because external workers have their own safety outcomes. As an editorial interpretation, document-based approval requires follow-up during work, verification of controls and treatment of failures. The existence of an approval process does not demonstrate that every supplier is risk-free or justify omitting recorded subcontractor accidents. Sources: Supplier approval and subcontractor injury outcomes; OHS results and rate definitions.
Accidents: employees and external workers
In 2025, the group recorded 2,326 recordable employee accidents and 928 involving external workers. Recordable injury rates were 16.14 and 6.82 respectively per million hours worked. Lost-time accident frequency uses a different base: 200,000 hours. It was 1.93 for employees, compared with 2.03 in 2024, and 0.84 for external workers, compared with 0.79. Both series exclude commuting accidents; they should not be compared directly without retaining the definition and denominator. Sources: OHS results and rate definitions.
The group reported zero work-related fatalities among employees and three among external workers in 2025; it also reported zero and three for 2024. The value-chain report identifies the latter as subcontractors. Consequently, “zero fatal accidents” without specifying the population would be incomplete. The improvement in employee accident frequency coexisted with a deterioration in the external-worker rate and three deaths in that population. Sources: OHS results and rate definitions; Supplier approval and subcontractor injury outcomes.
Health and wellbeing at work
The 2025 initiatives include meetings with occupational psychology professionals, mental-health and nutrition campaigns, influenza vaccination, visual health and smoking cessation. The headquarters provides medical consultations and nursing, complemented by specialist services; some services are available to employees by video consultation. These are company-reported services and initiatives, rather than evidence that psychosocial risks have been eliminated or a specific disease reduced. Sources: Safety and health measures implemented in 2025.
From a prevention perspective, their useful role is complementary: promoting habits and access to healthcare should be assessed alongside working conditions, risk assessment and participation. A wellbeing campaign and a control addressing a hazardous exposure deal with different problems. This interpretation does not attribute clinical outcomes to Acciona that the cited report does not demonstrate. Sources: Prevention and lessons learned in 2025; Safety and health measures implemented in 2025.
Renewables and the value-chain footprint
Renewable activity does not make the entire group’s emissions zero. For 2025, the report presents total Scope 1, 2 and 3 emissions on a market-based basis in two blocks: 3,593,769 tonnes of CO₂ equivalent for Acciona excluding Nordex and 5,256,334 for Nordex. Comparable 2024 figures were 3,234,269 and 4,704,408 respectively. Both blocks increased; this reading avoids equating renewable generation with an absence of impacts from construction, equipment or supplies. Sources: 2025 total emissions and methodological limitations.
The tables exclude assets held for sale; the document reports a separate 50,820 tonnes of Scope 1 and 2 emissions from those assets in 2025. It also explains work on an alternative Scope 3 methodology based on physical quantities and life-cycle analysis, which was not incorporated into the consolidated tables because the base year could not be recalculated comparably. This is a relevant methodological limitation, rather than an achieved emissions reduction. Sources: Emissions scope and assets held for sale; 2025 total emissions and methodological limitations.
Competition case and reported appeal status
In July 2022, Spain’s CNMC fined Acciona Construcción EUR29.4 million in the Obra Civil 2 case concerning practices that distorted infrastructure procurement. The administrative sanction relates to that company and proceeding; it is not a criminal conviction concerning occupational accidents. Sources: CNMC: 2022 Obra Civil 2 sanction.
The 2025 sustainability report states that Acciona Construcción appealed and that the effects of the decision, including payment and a possible contracting prohibition, were provisionally suspended. The company disputes the decision’s legality. This is the position described in that report, rather than an assertion that a final favourable judgment already exists or an undocumented subsequent court update. Sources: 2025 report: appeal and suspension of effects.
What this case contributes to prevention
Acciona illustrates a practical challenge: bringing construction, energy assets, factories and suppliers into one group without erasing their differences. Its documents offer identifiable practices—3D lessons, Brazilian alarms, leadership, Nordex rules and Acciona Energía audits—and results requiring a distinction between employees and external workers. The most useful comparisons retain each figure’s year, population, unit and scope. Sources: 2025 accounts: identity and activities; Safety and health measures implemented in 2025; OHS results and rate definitions.
As an editorial conclusion, the lesson is not to copy a programme name, but to establish where it applies, which hazard it seeks to control and how its effectiveness is verified. The coexistence of prevention measures and serious accidents shows why a policy or certification cannot replace monitoring actual working conditions.

Frequently asked questions
Are Acciona and Acciona Energía the same company?
No. Acciona, S.A. heads the diversified group, while Acciona Energía is its renewable business organised as a separate subgroup. The 2025 accounts place the year-end interest at 91.11%. Acciona’s consolidated figures include that business and should not have its figures added again. [1] · [2]
How many people work at Acciona?
The comparable measure used here is an average workforce of 68,502 full-time equivalents in 2025. It weights days and working-time commitments; it is not the number of individual people employed at year-end. [1] · [2]
What specific safety measures does Acciona document?
The 2025 report describes a 3D lessons-learned library, alarm management in Brazilian construction and concessions, leadership and dialogue programmes, Nordex Life Saving Rules and Acciona Energía audits. Each initiative retains its scope and is not automatically attributed to every activity. [1] · [2]
Did Acciona have zero fatal accidents in 2025?
The zero figure refers to employees. The report records three work-related deaths among external workers, identified as subcontractors in the value-chain section. Both figures are required to describe the group’s outcomes. [1] · [2]
