Tamil Nadu is drawing 19,004 MW as of 2026-06-18T03:00:00+00:00 IST, sourced from the India Energy Atlas state-page-live snapshot.
Renewables (solar, wind, hydro, nuclear) account for 10.6% of in-state generation in Tamil Nadu as of 2026-06-18T03:00:00+00:00 IST.
Tamil Nadu's current grid carbon intensity is 798 gCO2/kWh as of 2026-06-18T03:00:00+00:00 IST, computed from the metered fuel mix using CEA v18 lifecycle emission factors.
Today's peak demand in Tamil Nadu fell at 00:30 IST. Long-run peaks land in the evening (7-9 pm IST) on the residential lighting load.
Distribution in Tamil Nadu 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 Tamil Nadu 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).
Tamil Nadu is drawing 19,004 MW of electricity at the current hour (2026-06-18T09:00:00+05:30 IST), per the India Energy Atlas state-page-live snapshot.
The most recent in-state generation stack for Tamil Nadu is dominated by wind at 29.2% of the metered mix. Grid carbon intensity is 798 gCO2/kWh.
Demand for Tamil Nadu is sourced from a live SLDC scrape (metered, no disaggregation needed).

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.

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.
No solar capture-rate payload returned for Tamil Nadu.
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.

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.
