West Bengal Power Development Corporation Limited (WBPDCL) plays a central role in supplying reliable electricity across West Bengal through its thermal power stations and generation assets. As electricity systems worldwide move toward greater flexibility and instantaneous balancing, effective real-time generation operations are critical. This essay outlines why real-time generation matters for WBPDCL, the best practices it should adopt, operational challenges, and recommendations to improve real-time performance and reliability.
Auxiliary power consumption (APC)—the electricity used by coal mills, ID/FD fans, pumps, and ash handling—directly reduces net real-time generation. WBPDCL’s best plants keep APC between 6.5% and 8.5%.
Real-time actions to reduce APC:
A 1% reduction in APC on a 500 MW unit releases an additional 5 MW to the grid—worth crores annually.
For WBPDCL, "Real Time Generation Best" is not a destination but a discipline. It is the seamless fusion of man, machine, and milliseconds. In a state where power demand can surge with a sudden summer squall or a festive evening, WBPDCL’s commitment to real-time excellence ensures that West Bengal not only has light—but reliability, efficiency, and grid leadership.
Real time. Right time. WBPDCL time.

WBPDCL developed an in-house mobile app called "Gentrack" (Generation & Rake Tracking), which won the ASSOCHAM Mobile App Utilities Award What it does
: It provides management with live data on electricity generation and coal rake movements via a secure internet platform. A 1% reduction in APC on a 500
: This real-time visibility allows for rapid business decisions, helping to maximize generation and minimize power outages. The Path to Self-Sufficiency
WBPDCL's turnaround was also driven by securing its own fuel supply. By FY2024-25, the corporation achieved zero dependence on Coal India
, meeting 100% of its requirements through its own captive mines. The Times of India Production Growth
: Coal production surged from 6.25 million metric tonnes in 2021 to over 18.6 million tonnes in recent years. Cost Savings

The use of wind power has not only reduced the state's dependence on fossil fuels but also helped to decrease greenhouse gas emissions.
Biomass: A Sustainable Alternative
Biomass is another significant contributor to WBPDCL's renewable energy portfolio. The corporation has established biomass-based power plants that use agricultural waste and other organic materials to generate electricity. These power plants operate on a 24/7 basis, producing electricity in real-time to meet the state's growing power demands. The use of biomass has not only helped to reduce waste but also provided an additional source of income for local farmers.
Pumped Hydroelectricity: A Reliable and Efficient Source
Pumped hydroelectricity is a crucial component of WBPDCL's renewable energy strategy. The corporation operates several pumped hydroelectric power plants, which store excess energy generated during off-peak hours and release it during peak hours to meet demand. This technology ensures a stable and reliable supply of electricity to consumers. The pumped hydroelectric power plants also help to regulate the grid frequency, ensuring a smooth and efficient transmission of power.
Real-Time Generation: A Game-Changer in Renewable Energy
WBPDCL's real-time generation of electricity using wind, biomass, and pumped hydroelectricity has been a game-changer in the renewable energy sector. The corporation's ability to generate electricity in real-time has helped to:
Conclusion
WBPDCL's real-time generation of electricity using wind, biomass, and pumped hydroelectricity has set a precedent for other states to follow. The corporation's innovative approach has demonstrated that renewable energy can be a reliable and efficient source of power. As India continues to transition towards a low-carbon economy, WBPDCL's efforts will play a vital role in shaping the country's renewable energy landscape. With a strong commitment to sustainability and innovation, WBPDCL is poised to lead the way in India's renewable energy sector.
