Engineering the future of renewables - data-driven and sustainable

Dekorative Wolke

SUSTAINABLE ENERGY. CLEAR SOLUTIONS.

Voltares supports the development of renewable energy projects with technical expertise, independent analysis, and practical project experience.
We help developers, investors and operators turn complex energy projects into viable, bankable solutions.

Responsible renewable energy development requires careful consideration of environmental impacts from the earliest planning stages. We help identify potential impacts on ecosystems and biodiversity and ensure they are managed throughout the project lifecycle through biodiversity protection, pollution prevention, responsible resource use and environmental monitoring.

Renewable energy projects succeed when they create value for both the environment and local communities. We promote transparent communication and early engagement with municipalities, landowners and stakeholders, ensuring fair access to project information and clear channels for feedback in line with international best practices.

Integrity and transparency are fundamental to how we work. Voltares maintains strict standards against corruption, bribery and conflicts of interest, and operates in full compliance with Austrian law, EU regulations and international ethical standards. We promote responsible data protection, confidentiality and fair business practices across all projects and partnerships.

WIND ENERGY

Data-driven planning for succesful wind projects

Wind energy is a cornerstone of the energy transition and requires careful technical planning to unlock its full potential. Voltares supports developers, investors and operators with wind resource assessments, site analysis and wind farm layout optimization based on advanced modelling and long-term weather data. Our work delivers reliable yield forecasts and technically robust project designs that support successful development and investment decisions.

PHOTOVOLTAICS
