Electricity load calculator

Set the quantity for each appliance you have. Wattage is a Pakistan average — adjust if your nameplate says otherwise.

DISCOs typically assume 0.6–0.7 (you don't run every appliance at full power simultaneously). Set 1.0 to see worst-case connected load.

Use this sanctioned load figure on Form A-1 when applying for a new meter, or on the Load Increase application if upgrading. Your DISCO will size the transformer connection and security deposit off this number.

• Single-phase residential: Rs. 3,000 per kW of sanctioned load (LESCO, IESCO, GEPCO, FESCO, MEPCO). K-Electric slightly higher.
• Three-phase residential: Rs. 8,000 per kW.
• Commercial: Rs. 15,000 per kW single-phase / Rs. 20,000 per kW three-phase.
• Deposit is refundable when you disconnect the meter and settle final bill — carry it forward on transfers via name change form.

1. Under-sizing to save deposit: If you install a 1.5 ton AC on a 3 kW sanctioned meter, the DISCO detects the load and issues an LIO within 2–3 bills.
2. Ignoring the water motor: Starting torque on a 1 HP submersible pump draws 3,000 W surge — this trips single-phase meters at their peak limit.
3. Not planning for solar: Adding 10 kW solar later means changing the meter to a bidirectional net-meter — cheaper to spec it right on day one.
4. Skipping the geyser: One 1,800 W geyser doubles winter evening peak load. Include it even if you rarely use it — DISCO sizing must cover peak.
5. Confusing HP with kW: 1 HP ≈ 0.75 kW input at 100% efficiency, but pump/motor efficiency drops to 60–70% — a 1 HP motor draws ~1.1 kW from the meter.
