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 capture-rate rows for Tamil Nadu yet — the nightly writer fills this once the IEX area-clearing prices and SLDC actuals are both present for the previous IST day.
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.
