How many units (kWh) does a water motor / pump use per month?

Running 1 hours a day at 750 W, a water motor / pump consumes about 23 units per month — that's 0.8 units per day.

How much does it cost per month on the 200-unit slab?

On the Unprotected 101–200 unit slab (Rs. 22.95/unit) the energy charge alone is about Rs. 516. Add ~Rs. 68 for FPA + QTA and 18% GST on top.

Is a water motor / pump cheaper to run on protected tariff?

Yes — at Rs. 11.69/unit (protected slab 1–100 units) the same 23 units cost only Rs. 263, roughly half. But qualifying requires staying under 200 units total for 6 months, which is hard when this appliance alone uses 23 units.

Does running it during off-peak hours save money?

Only if you have a Time-of-Use (TOU) meter — typically 3-phase domestic, commercial A-2 or industrial B-2. On a flat single-phase domestic meter the tariff is the same 24 hours. See your DISCO's peak-hours page for exact windows.

Will solar make this appliance free to run?

Solar cuts the daytime portion of this load to nearly zero. Under the 2026 net-billing regime, exported units are worth Rs. 11–13 vs Rs. 27–42 for units you self-consume — so timing the appliance to run in daylight matters far more than it did on old net-metering.

Water motor electricity cost in Pakistan (2026)

A 1-HP domestic water pump pulls 750 W plus a 3× starting surge. Running 1 hour a day it adds Rs. 200–850 per month — but a leaking overhead tank float can push that to 3 hours a day silently.

How much energy does a water motor / pump use?

Timeframe	Energy used	Notes
Per hour	0.75 kWh	Steady-state draw
Per day	0.75 kWh	1 hours of runtime
Per month	23 kWh	Full month at daily duty cycle
Per year	270 kWh	Year-round load

Note: the water motor / pump briefly pulls 2,200 W during compressor start-up. Sustained draw settles at 750 W within ~30 seconds. Sizing a UPS or solar inverter must account for the surge.

Cost per slab — NEPRA Unprotected Residential (FY 2025–26)

Slab	Rs./unit	Per hour	Per day	Per month
1–100 units	16.48	Rs. 12.36	Rs. 12	Rs. 371
101–200 units	22.95	Rs. 17.21	Rs. 17	Rs. 516
201–300 units	27.14	Rs. 20.36	Rs. 20	Rs. 611
301–400 units	32.03	Rs. 24.02	Rs. 24	Rs. 721
401–500 units	35.24	Rs. 26.43	Rs. 26	Rs. 793
501–600 units	36.66	Rs. 27.49	Rs. 27	Rs. 825
601–700 units	37.80	Rs. 28.35	Rs. 28	Rs. 850
Above 700 units	42.72	Rs. 32.04	Rs. 32	Rs. 961

Energy charge only. Add ~Rs. 68/month for FPA + QTA at typical rates, then 18% GST on the total. Electricity duty and PTV fee are also stacked — see the full electricity bill calculator for the complete tax pass-through.

Protected consumers (≤200 units, 6-month rule)

Slab	Rs./unit	Per month cost
1–100 units	11.69	Rs. 263
101–200 units	14.16	Rs. 319

Check your Protected consumer eligibility — the ≤200 unit rule is strict and one bad month resets the 6-month counter.

Cut the running cost

Install a float valve on the overhead tank — it stops the pump automatically when full.
Use a soft-starter for pumps above 1 HP — cuts inrush by 60% and extends motor life.
Solar-DC pumps eliminate this load entirely; a 1-HP solar pump kit pays back in 2–3 years.

Fine print

1 HP = 746 W. Efficiency losses mean actual draw is closer to 850 W under load, and 3× that for the first 2 seconds.
