Every Meralco bill has a line that confuses people: the system loss charge. Some call it “generation loss,” but the official name is system loss, and it is one of the most controversial items on your electric bill right now.
President Ferdinand Marcos Jr. called for removing it from consumer bills in his 2026 State of the Nation Address, the Energy Regulatory Commission backs the push, and Senate President Win Gatchalian has filed a bill to abolish it. Here is what system loss actually is, how much you pay, and what removing it would mean for the average Pinoy.
What is system loss?
System loss is the electricity that disappears between the power plant and your home. Some of it is technical: when electricity travels through copper wires, resistance turns a small portion into heat, so the farther the power travels, the more is lost.
Some of it is non-technical: power that is stolen, lost to faulty meters, or unaccounted for in the network. Both types are real costs that someone has to pay.
Meralco chairman Manny Pangilinan put it plainly: “It is not a question of inefficiency, it’s just the way it is. The real question is who bears the cost?”
How much is it on your bill?
For Meralco customers, the system loss charge typically accounts for 5% to 6% of the total monthly bill. On a PHP 5,000 bill, that is roughly PHP 250 to PHP 300 a month, or PHP 3,000 to PHP 3,600 a year.
Meralco’s system loss rate stood at 5.72% in the first quarter of 2026, below the 6.5% cap set by the Energy Regulatory Commission. The industry-wide cap is higher, at 8.5%.
Meralco itself notes that only about 12% of your bill goes to Meralco. The rest is pass-through charges for generation, transmission, and other costs, including system loss.
What is the fight about?
Marcos Jr. said in his SONA that it is time to remove system loss charges that are passed on to consumers. The ERC has backed the proposal, and Gatchalian filed a bill seeking to end the charge, arguing that Filipino families should not pay for electricity they never used.
Gatchalian believes distribution utilities can shoulder the cost, which he estimates at around PHP 45 billion for the industry.
Meralco strongly disagrees. Pangilinan warned that forcing the industry to absorb the losses would cost “tens of billions of pesos,” and said “We will not survive” without passing the cost along.
What would removing it mean for you?
If the charge is removed, your monthly bill would drop by roughly 5% to 6%. On the average residential bill, that is a meaningful, permanent reduction every single month.
But the savings come with a question: who pays for the lost power instead? If the government subsidizes it, taxpayers pay through other channels. If distribution utilities absorb it, they may cut maintenance or delay network upgrades, which could hurt service quality in the long run.
There is also a fairness argument on the other side. Electricity theft and pilferage are a real problem in some areas, and the system loss charge spreads that cost across all customers. Removing it without fixing theft means honest bill payers subsidize the losses in another way.
The bottom line
System loss is not a scam line on your bill. It is a real cost of delivering electricity, split into technical losses from physics and non-technical losses from theft and inefficiency. The debate is not whether it exists, but who should pay for it.
For the average Pinoy, the proposal is simple and appealing: about 5% off the bill, every month, no action needed. Whether it actually happens depends on Congress, the ERC, and whether the industry and the government can agree on who eats the cost. Either way, it is the biggest electricity bill change on the table in 2026.
