If you run a business in the Philippines, you already know the feeling. Every month, the Meralco bill arrives and the number is higher than you planned for. In the first four months of 2026 alone, Meralco raised residential and commercial rates three consecutive times, bringing the average residential rate to P14.33 per kWh in May.
For commercial and industrial operators, the numbers are even more stark. Demand charges alone, which cover your facility’s peak power consumption, can account for 25 to 35 percent of your monthly bill. That’s money leaving your business every month regardless of how much energy you actually use.
The good news: Filipino businesses are no longer waiting for the grid to get cheaper. They’re building their own energy systems. Here’s a practical breakdown of what’s driving high electricity costs, and what you can actually do about it.
Why Your Meralco Bill Keeps Going Up
Understanding the breakdown of a commercial Meralco bill is the first step to reducing it. Most business owners focus on the generation charge — the cost of the electricity itself — but there are several components that add up:
-
— the largest component, covering the cost of power from generating plants. Tied to global fuel prices, which means it rises when oil and gas prices spike due to geopolitical events.Generation charge
-
— covers the cost of moving power through the national grid. With 75 of the Philippines’ 258 planned transmission projects still incomplete as of 2024, transmission costs have been adding P0.80 per kWh to consumer bills.Transmission charge
-
— Meralco’s own infrastructure cost for delivering power to your meter.Distribution charge
-
— billed at P650 to P900 per kVA per month based on your facility’s peak demand. This is where most commercial operators leave the most money on the table.Demand charge
-
— additional layers that are largely fixed.System loss charge, universal charges, and taxes
The demand charge is particularly punishing for businesses like cold storage facilities, BPOs, manufacturing plants, and hospitals that run high-load equipment during peak hours. Even if you optimize your consumption, the demand charge is based on your single highest-demand moment in the month.
In May 2026, Meralco’s overall rate landed at P14.33 per kWh after three consecutive monthly hikes. Meralco’s own vice president noted the decrease was only achieved through emergency regulatory intervention — the underlying pressure from fuel costs and transmission constraints remains.
