Read NowWest Bengal sits in the Eastern Regional grid (IEX zone: ER), drawing the bulk of its power from coal-dominated thermal plant in the Damodar Valley corridor and state utilities. At 11,764 MW of live demand (as of 2026-05-31), it ranks among the larger Eastern Region consumers. The defining characteristic of its current mix is a carbon intensity of 917.1 gCO2/kWh averaged over the recent ~48h window — one of the heaviest-emitting profiles measurable on the Atlas platform — reflecting an RE penetration that stood at only 4.1% of generation in the latest hourly slice. Peak supply reliability, however, is not presently a stress point: the p95 peak deficit reading is 0.0%, indicating that demand has been met at peak on virtually all measured days in the recent sample period. The open-access HT charge stack sits at INR 3.71/kWh, a material cost signal for industrial and commercial captive consumers. AT&C losses for the state DISCOM network were 19.2% in FY23, pointing to a distribution network that continues to consume financial headroom needed for capital investment.
Live SLDC telemetry placed West Bengal's demand at 11,764 MW as of 2026-05-31 20:49 UTC. Fuel-mix data for the latest hourly slice (2026-06-01 02:00 UTC) shows renewable energy contributing 4.1% of total generation — a low absolute share consistent with the state's historically coal-heavy installed base. Over the recent ~48h window (2026-05-30 02:30 UTC to 2026-06-01 02:00 UTC), the RE share declined by 2.0 percentage points, a short-window delta that reflects hour-to-hour variability in hydro and wind dispatch rather than any structural directional signal. Thermal generation is consequently filling the residual load at high dispatch levels. On the supply-adequacy side, the p95 peak deficit reading from POSOCO PSP data (as of 2026-05-30) is 0.0%, meaning that at the 95th percentile of peak-hour observations in the measured sample, West Bengal recorded no shortfall between peak demand and peak met. This is a positive reliability indicator in isolation, though the absence of transmission ATC/TTC data (Atlas endpoint not yet integrated for this state) prevents a full corridor-level bottleneck assessment. Multi-year demand CAGR is also not yet computable from current Atlas feeds.
West Bengal's RE share of 4.1% in the latest generation slice is materially below the national trajectory implied by central RPO targets. The recent ~48h window delta of -2.0 pp is a short-term dispatch movement, not a structural trend indicator; no multi-year demand CAGR or long-horizon generation aggregator is currently available from Atlas to characterise directional momentum. The provisional RPO compliance figure of 11.8% (FY23, sourced from WBERC tariff orders and Prayas review; marked modelled/provisional) should be treated cautiously — it indicates a significant gap relative to central RPO obligations for that year, but the estimate requires verification against final regulatory filings. Carbon intensity averaged 917.1 gCO2/kWh over the recent ~48h window, reflecting the coal-dominant dispatch stack. This is a high-intensity reading; reduction would require both incremental RE capacity addition and a change in merit-order dispatch. RPO compliance data is available only as a provisional estimate for FY23; a verified, current compliance figure is not yet integrated into Atlas. Absence of a long-term generation aggregator means multi-year RE capacity addition trajectories cannot be computed from current platform data.
The quantifiable DISCOM health signal available is AT&C losses of 19.2% (FY23, covering the state's single reporting DISCOM entity per PFC data). A loss level at this magnitude implies meaningful revenue leakage relative to units input — every percentage point of AT&C loss directly compresses the DISCOM's ability to service debt, fund capex, or absorb subsidy rationalisation. The HT open-access charge stack (CSS + wheeling + transmission + loss charges combined) is INR 3.71/kWh as of FY2025-26 tariff year. This figure serves as a proxy for the cost-of-power signal facing large industrial open-access consumers; at this level it is a non-trivial barrier to behind-the-meter captive RE adoption. Residential tariff data is not yet available — the Atlas tariff endpoint requires an API key not yet provisioned, so no blended or slab-wise consumer tariff can be cited. IEX DAM area prices for the ER zone are also currently absent from the upstream feed, preventing a market-price-versus-regulated-tariff spread analysis. Transmission ATC/TTC capacity data for West Bengal corridors is not yet populated in the Atlas database.
Over a 1-to-3 year horizon, West Bengal's energy posture is characterised by three concurrent pressures. First, at 4.1% RE share and 917.1 gCO2/kWh carbon intensity, the state's generation mix is deeply coal-dependent; any decarbonisation trajectory will require sustained capacity addition in solar and wind, as well as regulatory enforcement of RPO obligations — the FY23 provisional compliance figure of 11.8% suggests material headroom exists and enforcement pressure will likely intensify. Second, the 0.0% p95 peak deficit is a near-term stability asset, but the absence of transmission ATC data means corridor constraints that could bind as RE capacity scales are not currently visible. Third, AT&C losses at 19.2% (FY23) remain the principal drag on DISCOM financial sustainability; without reduction — through metering, collection, and network investment — tariff revision headroom narrows and cross-subsidy structures become increasingly difficult to sustain. The open-access HT stack of INR 3.71/kWh is the primary market signal available for industrial cost benchmarking in the absence of DAM price data. Multi-year demand growth rate cannot be cited due to the absence of a long-horizon Atlas aggregator.
