Read West Bengal newsWest Bengal is drawing 9,062 MW as of 2026-10-02T19:00:00+00:00 IST, sourced from the India Energy Atlas state-page-live snapshot.
Renewables (solar, wind, hydro, biomass) account for 4.8% of in-state generation in West Bengal as of 2026-10-02T19:00:00+00:00 IST. Nuclear and imports are excluded.
West Bengal's current grid carbon intensity is 906 gCO2/kWh as of 2026-10-02T19:00:00+00:00 IST, computed from the metered fuel mix using CEA v18 lifecycle emission factors.
Today's peak demand so far in West Bengal occurred at 00:30 IST. The value remains provisional until the current IST day ends.
Distribution in West Bengal is handled by one or more state-licensed DISCOMs; see the DISCOM card on the state page for the live roster.
The day-ahead demand forecast for West Bengal runs at single-digit MAPE; we publish the rolling 30-day MAPE on the State MAPE History card so readers can audit it themselves. Live demand comes from the SLDC scrape when available; non-SLDC states use the Atlas DISCOM disaggregation pipeline (Tier-A/B/C provenance, P10/P50/P90 bands).
West Bengal is drawing 9,062 MW of electricity at the current hour (2026-10-03T01:00:00+05:30 IST), per the India Energy Atlas state-page-live snapshot.
The latest modeled in-state generation mix for West Bengal is dominated by Coal at 95.2%. Grid carbon intensity is 906 gCO2/kWh.
Demand for West Bengal is sourced from a live SLDC scrape (metered, no disaggregation needed).
The day-ahead hourly demand forecast for West Bengal publishes a ±1.5σ band over the next 24 hours — per-state model v20 (holdout MAPE 3.9%); level-calibrated x2.00 vs canonical trailing 24h.

Demand's sensitivity to temperature (MW per degree) is what turns a heatwave forecast into a load forecast. A high, tight slope means cooling load dominates and peaks are weather-driven and forecastable; a weak or noisy slope means the swing factor is something else — industrial shifts, agriculture, or a data gap worth questioning.
We do not show a modeled-vs-actual chart for West Bengal because no audited live SLDC interval served-load actual; the available source is modeled, a daily peak, dead/restricted, or otherwise outside the pinned L(s,t) estimand. Accuracy scoring requires an independent interval actual.
measured but not on the IEA-1763 verified-<5% list — no green badge until the leak-free spike verifies this state on normal days.

Shortfall
vs FY23 target
A Renewable Purchase Obligation is statutory, not aspirational: a state utility must source a set share of its energy from renewables or pay a penalty. A widening shortfall against the MNRE trajectory is an early signal of either a procurement gap or a banked-REC scramble at year-end — both move power and REC prices.
Grid cleanliness
Each cell is one hour's grid carbon intensity. Greener = cleaner, browner = more fossil — the green hours are when discretionary load is cheapest on emissions.

Generation mix
Each band is a fuel's share of generation each hour — watch the solar wedge swell midday and coal hold the baseload, independent of total load.

Aggregate Technical & Commercial losses per PFC's Annual Integrated Rating of State Power Distribution Utilities. Backfilled FY16 onwards where published. Latest published edition is the 13th Rating (FY22-23 data); forward-year cells marked is_modeled=true.
AT&C (Aggregate Technical & Commercial) loss is the single clearest read on a distribution utility's solvency. Every percentage point is power delivered but never billed or collected; a worsening trend tells you a DISCOM is heading toward the payment delays that ripple back to gencos and IPPs.
