Monthly Electricity Bill for a 2-Storey House in Bekasi: Realistic 2026 Estimates

One of the most common questions from buyers of a 70 m² two-storey house: "If four people live here, roughly how much is the monthly electricity bill?" The answer depends heavily on habits, but there's a calculation framework that helps estimate it.

For a 2-storey type-70 m² home in Bekasi with 2,200 VA power (standard from most developers), using the 2026 PLN R-1 tariff for 2,200 VA: IDR 1,699.53/kWh.

The Main Contributor: Air Conditioning Dominates

In Bekasi's climate with average daytime temperatures of 32–35°C, AC almost certainly contributes 50–65% of total household electricity. This isn't a prediction — it's based on real consumption data.

Assumptions for one 1 PK AC unit (approximately 900W, 5-star inverter efficiency) running 8 hours per day:

• Daily consumption: ~0.9 kWh × 8 hours = 7.2 kWh
• Per month (30 days): 216 kWh
• Cost per AC per month: ~IDR 367,000

With two AC units (master bedroom + living room), AC alone already costs IDR 700,000–800,000 per month. It makes sense that families with two AC units regularly see bills exceeding IDR 1 million.

Appliance	Power (W)	Hours/day	kWh/month	Cost/month
1 PK Inverter AC (×2)	900W × 2	8 hrs	432 kWh	IDR 734,000
2-door refrigerator (300L)	80W	24 hrs	57.6 kWh	IDR 97,900
Electric water heater	350W	2 hrs	21 kWh	IDR 35,700
Washing machine (10kg)	500W	1 hr	15 kWh	IDR 25,500
LED TV 43" (×1)	70W	5 hrs	10.5 kWh	IDR 17,800
LED lighting (8 points)	60W total	6 hrs	10.8 kWh	IDR 18,400
Charger + router + misc	~50W	12 hrs	18 kWh	IDR 30,600
Total Estimate			565 kWh	IDR 959,900

For a family of four with normal usage patterns in Bekasi, a realistic monthly electricity bill for a 2-storey 70 m² house is IDR 900,000 – 1,200,000 per month, depending on AC intensity and whether there's WFH adding laptop hours and extra cooling needs.

Tips for Reducing Electricity Bills in a New Home

1. Choose inverter AC from day one

The power consumption difference between inverter and non-inverter AC can reach 30–40% for daily usage of 6+ hours. Inverter ACs cost IDR 500,000–800,000 more upfront, but the payback period from electricity savings is around 8–14 months.

2. Use AC timers strategically

For bedrooms, set the AC to turn off 2 hours after sleep and back on 1 hour before waking — not running all night. Savings per room: IDR 100,000–150,000 per month.

3. Gas or heat pump water heater

Electric water heaters are cheap to buy but expensive to run. Gas or heat pump water heaters are far more efficient for daily use. For a household where 3–4 people shower daily, the operating cost difference adds up quickly.
