Since West Bengal is part of the Eastern Regional Grid, the National Load Dispatch Center (NLDC) provides real-time data.
What makes WBPDCL’s real-time generation stand out?
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 | wbpdcl real time generation best
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.
Modern Supervisory Control and Data Acquisition (SCADA) and Distributed Control Systems (DCS)—such as ABB 800xA, Siemens T3000, or Yokogawa Centum VP—are the backbone of real-time excellence. Since West Bengal is part of the Eastern
Critical real-time loops to optimize:
The "best" real-time operation is characterized by less than 1% steady-state error in main steam temperature (target: 540±5°C) and pressure.
The difference between "average" and "best" real-time generation is often unplanned outages. WBPDCL has adopted Condition-Based Monitoring (CBM) and predictive analytics. The "best" real-time operation is characterized by less
Key predictive tools:
Best-in-class units schedule maintenance based on real-time degradation models, not just calendar days. This has helped WBPDCL achieve plant load factors (PLF) exceeding 75% in recent years, compared to the national thermal average of ~65%.
