Stem is a leading provider of AI-enabled clean energy software and services, and announced that its solar monitoring and optimization solutions will support the commercial operation of a 484 MW solar portfolio owned by Neovolt, one of Hungary’s largest asset owners. As part of a five-year agreement, Stem’s PowerTrack Web will manage and optimize eight utility-scale solar sites in Hungary, providing a unified view of the entire portfolio. Neovolt chose Stem for its proven expertise in technical execution and ability to adapt renewable energy solutions to local markets. With PowerTrack Web already managing over 720 MWp in the region, this partnership further strengthens Stem’s presence in Eastern Europe.
Ritter Antal, CEO at Neovolt, stated, “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.”
Sebastian Grenz, Managing Director of EMEA at Stem, mentioned “Stem 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.”
Stem has been a key contributor to the portfolio’s success, offering end-to-end support from the initial stages of its development. Leveraging its extensive experience with large-scale solar projects across Europe, Stem designed an efficient network and implemented industry best practices. Collaborating closely with local EPCs and its trusted partner, EXTOR Energy, for O&M services, Stem utilized its advanced Edge-to-Cloud solution, global engineering knowledge, reliable supply chain, and skilled production team to ensure Neovolt met its commercial operation deadlines.
Since its introduction, the PowerTrack Web system has been actively managing the portfolio, optimizing plant performance with scalable SCADA features tailored to the current and future needs of utility-scale solar plants. This includes remote control capabilities, real-time system updates, and strong security measures that support Service Organization Controls (SOC) compliance, even as requirements evolve. With enhanced production forecasting and efficient troubleshooting, Stem has streamlined operations across Neovolt’s assets, ensuring a smoother and more effective process.
