Add FCA (Rs 3.2/unit ×350 = Rs 1,120) → Final ≈ Rs 9,873

💡 How to Reduce Your IESCO Bill

• Stay under 200 units – Protected consumer rates save you thousands.
• Monitor your meter every 5 days – If you reach 160 units by the 25th, reduce usage drastically.
• Set AC to 26°C – Each degree below 26 adds 8% to your bill.
• Install LED bulbs – Replace 10 bulbs → save 30‑50 units monthly.
• Use fans instead of ACs when possible – Fans consume only 70W, ACs 1500W.
