The West Bengal Power Development Corporation Limited (WBPDCL) has transitioned from a struggling utility to being recognized as the best-performing power corporation in India. Recent Performance Milestones
In the 2024–25 financial year, WBPDCL achieved several all-time records in generation and financial stability:
Record Generation: It reached its highest-ever annual generation of 33,200 crore units (332 billion units) in FY 2024–25.
National Rankings: WBPDCL was ranked as the top generation entity in India with a consolidated Plant Load Factor (PLF) of 88.9%.
Plant Performance: Four of its thermal plants ranked among the top ten nationwide. Specifically, Bakreswar (BkTPP) has previously held the #1 spot in India, with Santaldih (STPS) at #2 and Sagardighi (SgTPP) at #5.
Financial Turnaround: The corporation posted its highest-ever operating profit of ₹1,000 crore in 2024–25, up from ₹812 crore the previous year. The "Long Story": How the Turnaround Happened wbpdcl real time generation best
The company's success is attributed to a "tenfold strategy" implemented under current leadership:
Coal Independence: In 2015, WBPDCL only produced 20% of its coal requirement internally. Today, 100% of its coal is supplied by its own captive mines, significantly reducing costs.
Cost Reduction: The cost of production was reduced by approximately 80 paise per unit (from ₹4.2 to ₹3.4) through efficiency improvements.
Modernization & Tech: Implementation of the PRAYOG ERP system (2017) and the use of Gentrack for real-time monitoring and unified login have streamlined operations.
Operational Excellence: Rigorous maintenance practices and plugging of pilferages allowed the corporation to increase total power for sale by 6 billion extra units. Real-Time Data & Digital Tools prompting immediate maintenance.
While WBPDCL manages real-time generation through sophisticated internal systems, public access to live generation metrics is typically hosted on their internal portals:
Gentrack Portal: Used for internal unified login and potentially real-time monitoring by employees.
PRAYOG ERP: Controls almost all key business processes, including plant maintenance and operations.
Official Performance Reports: WBPDCL publishes monthly O&M highlights, such as the record monthly generation of 3,046 MU achieved in January 2023. Future Outlook

Technology is useless without expert operators. WBPDCL’s best-performing shifts have:
Plant managers report that a well-trained control room team can recover from a partial trip in under 15 minutes—versus over 60 minutes for less prepared teams.
Let’s compare typical real-time performance across major WBPDCL plants:
| Plant | Installed Capacity (MW) | Best Achievable Real-Time Net MW (Peak) | Aux. Cons. (%) | Heat Rate (kcal/kWh) | |-------|------------------------|------------------------------------------|----------------|----------------------| | Sagardighi (Stage I & II) | 2,000 | ~1,850 | 6.8 | 2,380 | | Bakreshwar (Stage I) | 1,050 | ~910 | 8.5 | 2,550 | | Kolaghat | 1,260 | ~1,050 | 9.0 | 2,620 | | Santaldih | 1,000 | ~850 | 9.2 | 2,680 |
Note: Values are indicative based on historical performance; actual real-time data varies daily.
Sagardighi’s supercritical units (2x500 MW + 2x500 MW) currently exemplify the "best real-time generation" due to lower heat rate and advanced DCS.
