210 kWp of solar energy produced through the solution implemented by 4ENVIGO
The voestalpine Steel Service Center Romania project is an example of a fast and efficient implementation of an industrial photovoltaic solution, which combines technical performance with a significant economic and ecological impact. voestalpine demonstrates a proactive approach to the sustainability of its operations, consolidating its position as a responsible and innovative leader in steel and high performance metals industry.
General market context
The steel industry contributes around 7–8% of global CO₂ emissions, facing increasing pressure to reduce operational costs and meet sustainability requirements. In Europe, the steel sector is included in the EU Emissions Trading System, with steel production responsible for around 180–185 million tonnes of CO₂, or around 5–6% of the European Union’s total carbon emissions.
Legislative measures, such as Fit for 55, are driving the reduction of carbon emissions to 55% by 2030 and climate neutrality by 2050. At the same time, European legislation is encouraging the shift to renewables and increased energy efficiency in production chains. Demand for low-carbon steel from customers such as the automotive industry, which is itself facing ESG requirements from investors and business partners, is driving labelling and standardisation schemes for steel made with low carbon emissions in the production process.
For a well-established company like voestalpine AG, a global leader in the production of special steels and integrated industrial solutions, adopting energy efficiency measures has become a priority in the sustainable development strategy. The group, recognized for its high standards of quality and innovation, operates in an energy-intensive field, where any optimization has a direct impact on the profitability and sustainability of operations.
In this context, investments in increasing energy efficiency and the transition to green energy are becoming a strategic pillar for increasing competitiveness. Such investments offer the advantage of predictable operating costs, while also contributing to reducing the carbon footprint and strengthening the reputation of an environmentally responsible organization.
The challenge for voestalpine Steel Service Center Romania
With strong roots in the Austrian steel tradition of Linz, voestalpine AG has developed over the past 85 years from a local manufacturer to an international group focused on high-performance materials, steels and special alloys for applications with a strong technological component for the automotive, rail and energy industries. With over 49,000 employees, voestalpine AG has approximately 500 distribution and production companies operating on 5 continents, divided into 4 divisions: Steel, High Performance Metals, Metal Engineering and Metal Forming.
Opened in Giurgiu in 2012, through an investment of 20 million Euros, voestalpine Steel Service Center Romania has an annual production capacity of 130,000 tons of steel strips and sheets, materials intended for customers in the automotive, energy and household appliance industries. The constant increase in energy costs and price volatility led to the company’s decision to optimize its operating costs and adopt a sustainable solution for electricity production. At the beginning of 2025, voestalpine Steel Service Center started a market analysis to identify a partner specialized in industrial photovoltaic solutions, which would meet the following challenges:
- Energy costs predictability.
- Maintaining the continuity of production activities.
- Utilizing the available space, analyzing the soil characteristics and land orientation to obtain maximum energy efficiency.
- The need to comply with legal regulations in compliance with all applicable regulations regarding the safety and operation of photovoltaic plants.
Project description
The 4ENVIGO team coordinated all stages of the project, from preliminary study, approval, design, acquisition, transportation, construction, assembly and testing and launch into production. 356 Jinko Solar 590 W monocrystalline photovoltaic panels were used, recognized for their resistance in industrial operating conditions, 2 Huawei 100 kW inverters, with advanced monitoring and optimization functions of the energy flow, installed on a galvanized clamping structure, designed for stability and durability in environments exposed to vibrations and temperature variations.
The estimated life of the system is 25 years, with a guaranteed performance of 85.5%, which ensures a constant supply of green energy in the long term. The guarantees are conditional on the annual performance of preventive maintenance, provided by the 4ENVIGO team. Thus, technical assistance allows constant supervision of the system performance, monitoring of the generated energy, remote assessment of the efficiency of the solar panels and electronic components and the performance of essential maintenance activities.
The voestalpine project was distinguished by a record execution time, made possible by efficient collaboration between all parties involved. Compliance with the assumed deadlines was ensured by 2 4ENVIGO specialists, involved in project management and technical coordination of a design team consisting of 2 technical experts specialized in energy engineering and a team of 10 technicians, specialized in the assembly and installation of professional photovoltaic systems. On behalf of voestalpine Steel Service Center Romania, a local technical manager ensured operational coordination on the ground and access to the existing infrastructure, and a member of the management team ensured a rapid decision-making flow.
Project Impact
Increased energy independence
The photovoltaic plant will generate an estimated annual production of over 295 MWh, covering a significant part of voestalpine Steel Service Romania’s energy consumption.
Rapid return of investment
The solution is designed to bring annual savings of approximately 58,000 euros on the electricity bill, thus ensuring a rapid recovery of the investment.
Carbon footprint reduction
The system contributes to reducing the carbon footprint by approximately 90 tons of CO₂ annually, equivalent to the emissions generated by the annual energy consumption of over 50 households.

The solution
At the beginning of 2025, voestalpine Steel Service Center Romania evaluated the technical capabilities and references of several photovoltaic solution providers in the local market. Following market research, the company chose 4ENVIGO, due to the professionalism demonstrated in proposing a customized technical solution and the ability to deliver an integrated service package, which included not only the design, acquisition, installation and commissioning of the photovoltaic plant, but also technical consultancy in relation to public authorities, in order to comply with the regulations in force regarding the operation of such a plant.
The 4ENVIGO technical proposal started from a detailed analysis of the energy needs of voestalpine Steel Service Center Romania, evaluating the load curves, daily energy consumption, power peaks and the particularities of the existing infrastructure. Based on this data, a customized technical solution was configured, designed to ensure an optimal balance between performance, reliability and cost. After validating the economic and impact benefits, the solution proposed by 4ENVIGO received the approval of voestalpine management in October 2025. The project was executed in just 2 weeks, between 14 and 28 October 2025.
Commissioned on 28 October 2025, the project consisted of installing a photovoltaic plant with a total capacity of 210 kWp, mounted on the ground with a south orientation, to maximize the solar radiation output. Fully financed from Voestapine’s own funds, the system implemented by 4ENVIGO benefits from an estimated lifespan of 25 years, with a guaranteed performance of 85.5% at the end of the operating period. The panels benefit from a 12-year product warranty and a 25-year power performance warranty, while the inverters and mounting structure benefit from a 10-year warranty.
