Energy cost vs budget — last 12 m₹ lakh · July is month-to-date
ActualBudget
Last 12 m: ₹ 272.5 L actual vs ₹ 282.5 L budget — overrun concentrated in Apr–May (early heat wave, verified against weather-normalized baseline, not operations).
Plant efficiency — monthly average — last 12 mkW/TR · vs target
Every 0.1 kW/TR above target costs ≈ ₹ 7 L/yr at current load and tariffs. The Apr–Jul climb tracks the CH-3 condenser fouling — closing findings F-2607 and F-2555 recovers most of the gap.
