Stem, a global leader in artificial intelligence (AI)-enabled clean energy software and services, has announced a significant development in its partnership with Neovolt, one of Hungary’s largest asset owners. Under a five-year agreement, Stem’s award-winning solar monitoring and optimization solutions will be deployed to support the commercial operation of a 484 megawatt (MW) solar portfolio in Hungary. This collaboration highlights Stem’s expertise in optimizing renewable energy assets, underscoring the company’s strength in technical execution and its ability to adapt to local markets.
The agreement will see Stem’s PowerTrack Web system used to monitor, optimize, and control eight utility-scale solar sites in Hungary, providing a comprehensive view across Neovolt’s entire portfolio. PowerTrack Web’s ability to deliver real-time system updates, advanced troubleshooting, and enhanced production forecasting was a critical factor in Neovolt’s decision to partner with Stem. With over 720 megawatt peak (MWp) of installations in the region, Stem continues to expand its presence in Eastern Europe, cementing its position as a key player in the utility-scale solar market.
Ritter Antal, CEO of Neovolt, expressed confidence in Stem’s capabilities, noting, “We have seen Stem drive value throughout the commissioning of this portfolio with the invaluable support of Stem’s localized engineering expertise, well-aligned KPIs, and outstanding software solutions. Having built over 500MW of assets in Hungary, we must ensure the seamless operation and optimal performance of our portfolio supporting Neovolt’s renewable energy vision now and in the years to come. The combination of Stem’s powerful software solutions and experience in local markets made them the clear partner-of-choice. We look forward to continued successes as we scale our renewable energy portfolio.”
A Collaborative Approach to Large-Scale Solar Deployment
involvement in the Neovolt project began long before the first solar panel was installed. The company played an integral role in the early stages of the portfolio’s development, particularly in network design and integrating best practices from its extensive experience working with large-scale solar plants across Europe. Stem’s edge-to-cloud solution was deployed in close collaboration with local engineering, procurement, and construction (EPC) firms and the operations and maintenance (O&M) provider EXTOR Energy. This collaborative approach ensured that the solar portfolio met Neovolt’s target commercial operation dates.
One of the standout features of Stem’s technology is its advanced edge-to-cloud capabilities, which provide real-time monitoring and optimization of solar assets. PowerTrack Web, in particular, stands out for its ability to offer scalable SCADA (Supervisory Control and Data Acquisition) functionalities that meet both current and future needs of utility-scale photovoltaic (PV) power plants. Through remote power plant controls, the execution of real-time system updates, and strong security measures, Stem is able to promote compliance with Service Organization Controls (SOC) across Neovolt’s entire portfolio, even as requirements evolve over time.
PowerTrack Web: Enhancing Performance and Efficiency
Since its deployment, PowerTrack Web has proven essential in optimizing the performance of the Neovolt solar portfolio. By enabling flexible and scalable control systems, the software helps improve the efficiency of the plants by delivering accurate, up-to-date data and allowing for immediate response to any issues that may arise. The system’s capabilities include enhanced production forecasting, which is critical for managing energy output, and robust troubleshooting processes to minimize downtime and prevent costly operational delays.
Stem’s software also provides deep insights into plant performance, helping Neovolt fine-tune operations to maximize energy production while ensuring the longevity of the assets. The ability to monitor and control the entire portfolio from a single platform helps Neovolt’s operations team streamline management tasks, reducing complexity and improving overall productivity.
Local Expertise and Market Adaptation
Stem’s success in securing this partnership with Neovolt can be attributed to its deep understanding of local markets and the renewable energy landscape. The company’s experience in Europe, particularly in Eastern Europe, has positioned it as a trusted partner for utility-scale solar projects. Stem’s engineering expertise, combined with a robust supply chain and production capabilities, was instrumental in ensuring the project met its targets for commercial operation.
Stem’s ability to adapt to local conditions and regulatory environments is another key factor in the company’s growing footprint in Eastern Europe. The market for renewable energy in the region is expanding rapidly, and Stem has been quick to capitalize on this opportunity by providing solutions that meet the specific needs of the local market. By aligning its technology and services with local requirements, Stem has positioned itself as a leader in utility-scale clean energy asset monitoring and optimization in the region.
Looking Ahead: Scaling Renewable Energy in Eastern Europe
commitment to expanding its presence in Eastern Europe is evident in its partnership with Neovolt. The five-year agreement to support Neovolt’s 484 MW solar portfolio is just the beginning of broader strategy to scale its renewable energy solutions across the region. As Eastern Europe continues to invest heavily in renewable energy, is well-positioned to help organizations like Neovolt optimize their portfolios and meet their sustainability goals.
The success of this project also demonstrates Stem’s ability to execute complex, large-scale solar projects efficiently and effectively. The company’s proven track record in delivering results for utility-scale PV plants, combined with its innovative technology solutions, has earned it the trust of major asset owners and operators across Europe.
Sebastian Grenz on Stem’s Role in the Region
Sebastian Grenz, Managing Director of EMEA at , commented on the growing importance of the company’s presence in Eastern Europe: continues to strengthen its leading position in utility-scale clean energy asset monitoring and control across the growing Eastern European market. We are proud to have supported the successful commissioning of Neovolt’s renewable energy portfolio with our edge-to-cloud solutions. This five-year agreement reflects the culmination of Stem’s commitment and expertise in supporting seamless project execution and management of large-scale renewable asset portfolios.”
As demand for renewable energy increases globally, technology solutions are becoming essential in optimizing the performance of large-scale solar assets. The company’s advanced monitoring and optimization capabilities help asset owners maximize energy production while minimizing operational costs. This combination of high efficiency and low-cost operation makes solutions highly attractive to companies looking to scale their renewable energy portfolios.
The Future of Solar Energy in Eastern Europe
The renewable energy market in Eastern Europe is poised for significant growth in the coming years. Countries in the region are increasingly turning to solar power as a solution to meet their energy needs and sustainability goals. As these markets continue to develop, the demand for innovative technologies that can optimize the performance of solar assets will grow.
continued investment in the region is a testament to the company’s belief in the potential of Eastern Europe’s renewable energy sector. By providing cutting-edge software solutions and collaborating closely with local partners, is helping to accelerate the transition to a cleaner, more sustainable energy future. The company’s success in Hungary with Neovolt is just one example of how Stem is driving progress in the renewable energy sector across Eastern Europe and beyond.
