Barauni to Get New 800 MW Ultra Supercritical Thermal Power Unit, Battery Storage System Also Planned
Patna: बरौनी में लगेगी 800 मेगावाट की नई अल्ट्रा सुपर क्रिटिकल थर्मल यूनिट, बिजली उत्पादन बढ़ाने के साथ बैट्री स्टोरेज सिस्टम की भी तैयारीA feasibility study for the project is currently underway, and construction is expected to gain momentum once approval is received from the Ministry of Power.
A key highlight of the proposal is that the new thermal power unit will be accompanied by a Battery Energy Storage System (BESS). The storage facility will enable surplus electricity to be stored and supplied during peak demand hours, ensuring a more reliable and stable power supply across the state.
New Unit to Be Built on Land of the Old Closed Plant
According to official sources, there will be no land acquisition issues for the project. The proposed ultra-supercritical power unit will be constructed on the land occupied by an old thermal power unit that has already been decommissioned.
Using the existing land will significantly reduce project costs and speed up the construction process while avoiding delays associated with land acquisition and environmental clearances.
What Is Ultra-Supercritical Technology?
Ultra-supercritical technology is considered one of the most advanced and efficient technologies in coal-based thermal power generation. It operates at much higher steam temperatures and pressures than conventional thermal power plants, allowing greater energy efficiency.
One of its biggest advantages is that it requires 10–15 percent less coal to generate the same amount of electricity compared to conventional plants. Reduced coal consumption also lowers emissions of harmful gases such as carbon dioxide (CO₂), sulfur dioxide (SO₂), and nitrogen oxides (NOx).
The technology also consumes less water, making it a more environmentally sustainable option for large-scale electricity generation.
NTPC to Introduce Battery Energy Storage System in Bihar for the First Time
The project also includes the installation of a Battery Energy Storage System (BESS), marking the first time NTPC will deploy such technology in Bihar.
The storage system will allow excess electricity generated during periods of low demand to be stored in batteries and released into the grid during peak consumption hours. This will improve grid stability, enhance power reliability, and reduce the risk of shortages during periods of high demand.
Experts believe the battery storage system will also play an important role in integrating renewable energy sources such as solar and wind power into the electricity network in the future.
Better Power Supply During Peak Demand
Electricity demand in Bihar rises significantly during summer months and festive seasons. At times, the gap between demand and supply can create pressure on the power grid.
With the proposed battery storage system, excess electricity generated during normal hours can be stored and supplied when demand peaks. This will help ensure uninterrupted power supply and improve overall load management across the state's electricity network.
Major Boost to Bihar's Power Generation Capacity
Although Bihar has expanded its electricity infrastructure over the years, the state still depends significantly on power generated outside its borders.
At present, NTPC operates only one 800 MW power generation unit in Bihar, located at the Nabinagar Power Generating Company (BRBCL) Stage-II project in Aurangabad district.
The addition of another 800 MW unit at Barauni would significantly strengthen the state's power generation capacity and reduce its dependence on external sources.
Similar Projects May Come Up at Kahalgaon and Kanti
According to NTPC sources, similar 800 MW ultra-supercritical thermal power units could also be developed at the Kahalgaon and Kanti thermal power stations.
Feasibility assessments are being conducted to evaluate the potential for expanding power generation capacity at these locations as well. If approved, these projects could substantially increase Bihar's overall electricity production and support long-term industrial and economic growth.
Boost for Industrial Development
Energy experts believe reliable electricity is one of the key requirements for industrial growth.
The proposed projects are expected to improve power availability for industries, businesses, agriculture, and households across Bihar. Better electricity infrastructure will also make the state more attractive for domestic and industrial investment, creating new employment opportunities.
More Environment-Friendly Power Generation
Ultra-supercritical thermal technology is regarded as much cleaner than conventional coal-fired power plants. Lower coal consumption results in reduced greenhouse gas emissions and less air pollution.
In addition, the technology requires less water, helping conserve natural resources while improving overall energy efficiency. This is why most newly planned coal-based thermal power plants in India are now adopting ultra-supercritical technology.
A New Chapter in Bihar's Energy Sector
The proposed 800 MW ultra-supercritical thermal power unit and Battery Energy Storage System at Barauni represent a major step forward for Bihar's energy sector. Beyond increasing electricity generation, the project aims to modernize the state's power infrastructure through advanced technology, greater efficiency, and environmentally responsible operations.
Once the Ministry of Power grants final approval, construction is expected to begin. If completed as planned, the project will significantly strengthen Bihar's energy security, improve electricity reliability, and move the state closer to becoming more self-reliant in power generation while supporting future economic and industrial development.
