Meralco Rates Are Down for a Second Straight Month

Why Meralco Rates Increase
Meralco rate hikes happen when the overall cost of producing, purchasing, and delivering electricity becomes more expensive. While many consumers assume Meralco directly controls all charges, a large portion of the electricity bill actually goes to power suppliers, transmission operators, taxes, and government-mandated charges.
Electricity prices in the Philippines are affected by both local and global market conditions. Fuel prices, exchange rates, weather conditions, and electricity demand all influence the final cost consumers see on their monthly bills.
During hotter months, electricity demand increases significantly because households use air conditioners, electric fans, refrigerators, and cooling appliances more frequently. Higher demand places pressure on the Luzon grid and can increase spot market prices.
According to Meralco, only a portion of the monthly electricity bill goes to distribution charges. Generation, transmission, taxes, and government-related charges make up the majority of the total amount consumers pay.
Recent Rate Changes, Month by Month
Meralco’s rate moved in both directions over the last four months — a hike, then two straight cuts. Here’s exactly what happened and why, each time.

Lower ancillary & tax charges outweighed a higher generation charge |
September’s generation charge actually rose ₱0.4232/kWh — driven by peso depreciation and higher fuel costs from renewed Middle East conflict. The overall rate still dropped because ancillary service charges (NGCP’s Reserve Market fees) fell ₱0.3344/kWh, and taxes fell another ₱0.1657/kWh after the Malampaya gas facility finished maintenance, letting nearby plants use VAT-exempt local gas again.

Main Reasons Behind Meralco Rate Hikes
1
Higher Generation Charges
Generation charges are the largest component of the Meralco bill. These charges pay electricity suppliers and power producers. When fuel prices increase or power supply becomes tight, generation costs rise.
In April 2026, generation charges rose to ₱8.3864 per kWh from ₱7.8607 per kWh.
2
Peso Depreciation
Many power supply agreements and fuel purchases are denominated in US dollars. When the Philippine Peso weakens against the dollar, electricity generation costs increase.
The exchange rate climbed above ₱60 per US dollar during the March 2026 supply month, significantly affecting electricity costs.
3
Wholesale Electricity Spot Market (WESM)
Electricity prices in the spot market rise when demand exceeds available supply. During summer months, power demand increases sharply because of air conditioning usage.
Tighter supply conditions in the Luzon grid pushed WESM prices significantly higher.
4
Transmission Charges
Transmission charges cover the cost of delivering electricity through the national grid operated by the National Grid Corporation of the Philippines (NGCP).
Ancillary service charges and reserve market costs can increase overall transmission expenses.
5
Seasonal Electricity Demand
Summer months usually lead to 20% to 33% increases in household electricity consumption because cooling appliances operate longer.
Higher demand places pressure on the power grid and raises market electricity prices.
6
Global Fuel Market Volatility
International fuel supply disruptions, oil price increases, and geopolitical conflicts affect power generation costs in the Philippines.
Natural gas, coal, and oil prices heavily influence electricity rates.

How Higher Rates Affect Consumers
Even small increases in the per-kWh rate can significantly affect household bills, especially for homes with high electricity usage.
For example:
- 200 kWh monthly consumption = around ₱107 increase
- 300 kWh monthly consumption = larger monthly impact
- 500 kWh monthly consumption = around ₱267 increase
- Air-conditioned households typically experience larger bill increases
Homes using multiple cooling appliances during summer often notice the sharpest increases.
How to Reduce the Impact of Rate Hikes
While consumers cannot directly control electricity rates, there are practical ways to lower consumption and reduce overall bills.
1
Set Air Conditioners Properly
Set air conditioners to around 25°C and clean filters regularly to improve efficiency.
2
Unplug Unused Appliances
Many appliances continue consuming electricity even when turned off.
3
Use Natural Lighting
Open curtains and windows during daytime to reduce lighting usage.
4
Avoid Refrigerator Overloading
Proper airflow inside refrigerators helps reduce compressor workload.
5
Monitor Appliance Consumption
Track which appliances consume the most electricity and adjust usage patterns.
6
Use an Appliance Calculator
Estimate appliance costs and identify energy-hungry devices using a consumption calculator.
