This paper outlines the company’s transition toward a real-time data ecosystem, including:
The backbone of its operations is a fleet of five primary thermal power plants, with a total installed capacity of . The specific plants include:
is the largest state-owned power generation utility in West Bengal, India. It operates multiple thermal power plants with a combined installed capacity of over 7,000 MW. Real-time generation data reflects the actual electricity output (in MW) at each plant, updated typically every 5–15 minutes via the State Load Despatch Centre (SLDC) and National Load Despatch Centre (NLDC) portals.
Optimizing Grid Stability: The Power of WBPDCL Real-Time Generation
: In recent rankings, Bakreswar Thermal Power Station (BKTPS) secured the 1st rank in the country for PLF, followed by Santaldih (STPS) at 2nd and Sagardighi (SgTPP) at 5th. wbpdcl real time generation
Real-time monitoring of WBPDCL plants allows the West Bengal State Load Despatch Centre (WBSLDC) and WBPDCL to manage load variations.
The NPP hosts a Daily Generation Dashboard that tracks performance metrics for central and state utilities, including WBPDCL's plant-wise contribution.

This transparency allows investors, policymakers, and consumers to track how efficiently WBPDCL is utilizing its installed capacity (which includes the newer 660 MW supercritical units at Sagardighi and Santaldih). This paper outlines the company’s transition toward a
WBPDCL operates multiple thermal power plants: Sagardighi, Bakreshwar, Kolaghat, Bandel, and Santaldih. Real-time generation data (MW, MVar, frequency, auxiliary consumption) is essential for:
This indicates the state’s generation is 4,770 MW against a schedule of, say, 4,600 MW → WBPDCL is exporting ~170 MW to the grid.
Power Line Carrier Communication (PLCC) and dedicated fiber optic cables instantly send this data from remote plants to the WBPDCL headquarters and the West Bengal SLDC.
| Technology | Status | Benefit | |------------|--------|---------| | Upgraded RTUs (IEC 61850) | Pilot at Bakreshwar | 1 sec resolution | | PMU (Phasor Measurement Units) | Installed at 400 kV substations | 50 ms time-stamped data | | AI-based generation forecasting | Under evaluation (NITI Aayog grant) | Reduces DSM penalty by 15–20% | | Digital twin for Sagardighi Unit-5 | 2025–26 budget approved | Predictive maintenance | The NPP hosts a Daily Generation Dashboard that
WBPDCL's investment in real-time data lays the foundation for future technological upgrades. The next phase of evolution involves integrating Artificial Intelligence (AI) and Machine Learning (ML) algorithms into the real-time data stream.
WBPDCL’s real-time generation data, though partially public via NLDC, offers valuable insights for grid stability, plant performance, and energy accounting. By analyzing 5–15 minute interval data, stakeholders can detect outages, optimize dispatch, and forecast shortfalls. However, greater transparency in available capacity and frequency integration would enhance utility.
