Why Your Bill Went Up
- Summer generation surcharges. More AC demand = higher wholesale prices.
- Fuel surcharges change monthly. Tied to global oil and coal prices.
- New appliances or habits. A broken AC running 24/7 can double your kWh.
- Government mandate additions. Renewable energy and policy fees appear without warning.
How to Reduce Your Bill
- Switch to LED bulbs. 75% less energy than incandescent. Lasts 15+ years.
- Set AC to 26°C. Each degree cooler adds 5–10% to your bill.
- Unplug idle devices. Phantom power adds 5–10% monthly.
- Go solar. A 3kW system eliminates 60–80% of your bill in 5–7 years.
Common Questions
What is the average Meralco bill?
Average households use 150–250 kWh/month and pay ₱3,000–₱8,000. High-usage homes with heavy AC can hit ₱12,000+.
Why is Meralco the most expensive in the Philippines?
Meralco serves Metro Manila — high density, high demand, aging infrastructure. Rates reflect real generation and distribution costs.

Yes. File a complaint with Meralco customer service or the ERC within 60 days of the bill date. Document your usage with meter readings.
Does Meralco offer time-of-use rates?
Only for certain pilot areas. Most residential customers pay flat rates. Call 16211 to check if you qualify for off-peak rates.
Is solar worth it if my bill is ₱5,000/month?
Yes. At ₱60,000/year, a ₱300,000 solar system pays off in ~5 years, then produces free power for 20+ years.
