Key Takeaways
- Voith upgraded its Hydro Pocket to a cloud-based system for real-time hydropower monitoring.
- Hydro Pocket significantly improves plant efficiency with data-driven insights and faster issue resolution.
Voith Upgrades Hydro Pocket Solution
The upgraded hydropower software provides real-time insights, improving data, performance, and efficiency.
Voith upgraded its Hydro Pocket solution from only monitoring remotely through a closed circuit to a cloud-based system. The software solution was installed at the Ohsawagawa Hydropower Station in Japan in March 2025. Fuji Electric provided technical support throughout the project.
The Hydro Pocket dashboard facilitates seamless local use and underscores the importance of localized, customer-centric digital solutions. Plant owners can monitor, analyze, and optimize their hydropower stations through a simple, cloud-based application.
"Key benefits include faster decision-making, increased performance, and proactive issue resolution," said Dirk Fuchs, Head of HyService Digital & Automation at Voith Hydro. "Voith also provides additional insights and analysis through expert teams."
Real-time access to plant data includes information on energy production, plant operation status, and grid connection status. Additionally, it offers historical trend charts, automated standard reports, and combined operation and event data, transforming data into actionable insights. This significantly enhances efficiency and ensures seamless integration into daily operations.
"The implementation of the Hydro Pocket system has revolutionized our operations by providing real-time insights and supporting a more data-driven approach,” said a representative from the Yamagata Prefecture local government.
The representative said it has significantly improved its efficiency and paved the way for future predictive analysis and now sees the value of having more data and insights coming from our plant. The government is exploring further opportunities with Voith and Fuji Electric to add more sensors and extend the duration of our Hydro Pocket data storage.
"We're proud to see Hydro Pocket enter the Japanese market and support critical infrastructure in its digital transformation," said Sunil Pandiri, Chief Service Officer at Voith Hydro. "With this first reference project in Japan, we can strengthen our position as a trusted partner for hydropower digitalization and demonstrate the value of data-driven services for long-term operational success."

In mid-June, Voith and HeiTech Padu Berhad were awarded a contract to modernize the Temengor, Bersia, and Kenering hydropower plants in Malaysia to a total capacity of 472 MW. The upgrade to the three hydropower plants will extend their operational lifespan and increase the annual output of select turbine-generator units.
“This order represents a significant milestone for Voith and highlights the company's ongoing commitment and exceptional performance, while also reinforcing its goal to strengthen its presence in Southeast Asia’s hydropower market and advance its global development strategy,” said Hubert Geissberger, Head of Proposals at Voith Hydro.
The Sungai Perak-based project includes:
- Temengor hydropower station: four 100-MW Francis turbines
- Bersia plant: three vertical 24-MW Kaplan turbines
- Kenering station: three 40-MW Francis turbines.
The Bersia Group control center, which operates and controls all the river cascade power stations, will receive an upgrade.
The multimillion-euro rehabilitation includes the turbine-generator units, automation systems, and electrical and mechanical balance of plant auxiliary power station systems. The Temengor Hydropower Station is expected to achieve a 15% boost in output capacity.
