Belding India Limited, during India Energy Storage Week (IESW) 2026, unveiled an internal Hybrid Battery Energy Storage System (BESS) to boost the efficiency of diesel generator (DG)-based power systems while reducing fuel consumption and emissions. The device was announced by Shripad Yesso Naik, Minister of State for New and Renewable Energy in the Indian government. The introduction reflects the company’s dedication to developing more reliable and environmentally friendly backup power solutions that are developed and manufactured in India.
The Hybrid BESS is designed to optimise diesel generator operations by reducing diesel consumption by 40-80 percent, depending on the load profile.
The company said lower generator runtime translates into reduced fuel costs, lower maintenance requirements and a longer operational life for diesel generators.
The system also provides instant backup power while the diesel generator starts, helping prevent power interruptions. In addition, its peak load shaving capability enables the battery to handle sudden spikes in electricity demand, reducing the required diesel generator capacity and allowing generators to operate closer to their optimal efficiency range.
In addition to improving fuel efficiency, the Hybrid BESS is designed to deliver stable power with enhanced voltage and frequency regulation. The solution also supports the integration of renewable energy sources such as solar power into existing power systems.
According to the company, the system can help reduce carbon dioxide emissions and noise pollution associated with diesel generator operations while improving overall system reliability and uptime. These operational benefits are expected to lower the total cost of ownership over the system’s lifecycle.
According to Belding India, the Hybrid BESS is designed to be used in a variety of critical infrastructure and industrial applications. Data centers, manufacturing facilities, hospitals, airports, telecom towers, mining operations, oil and gas sites, defence installations, remote industrial locations, and building projects are among the target areas where dependable backup power is still crucial.
