Retail Aggregation Saves Acacia Estates Homes About ₱2 a Kilowatt-Hour, and the ERC Lets the Whole Estate Negotiate Together

Big electricity users have been allowed to shop for their own supplier for years. Homes and condos were too small to qualify. The Retail Aggregation Program lets small users pool their demand and shop as one big buyer. The ERC lowered the bar to 100 kW on 26 June 2026, and Acacia Estates clears that many times over.

Only the generation charge, which is the electricity itself, and the VAT on it. The sample computation in the briefing deck, built on the Rosewood Pointe common areas, shows it: generation drops from ₱7.47 to an example rate of ₱5.67 per kWh. Transmission, system loss, distribution, subsidies, and other charges stay exactly the same, because Meralco still owns the wires and still gets paid for them.

Here is the computation, using the briefing’s own figures: ₱16 per kWh for units today, and the deck’s sample generation price of ₱5.67 under the program.

For any other unit, the shortcut is ₱2.02 times your monthly kWh. A 400 kWh household saves about ₱806 a month. That is roughly 12% to 14% off a typical unit’s bill.

The bigger number on the slide comes from applying the common areas’ all-in rate of ₱9.56 to units. It’s an easy mix-up, since the common-area breakdown sits right beside it, but units keep paying their residential wire charges.

Two caveats. The ₱5.67 is an example from the deck, not a signed price, so the real saving depends on what the bidding produces. Ask for the unit price in writing. And Meralco’s generation charge moves every month, so the saving moves with it. If the supplier’s price is fixed and Meralco’s goes up, you save more. If Meralco’s goes down, you save less.

Neither DMCI nor the condo corporation sets this. Meralco’s ERC-approved tariff charges each customer class differently. Common areas are one large general-service account, which pays less per kWh for the wires. Homes pay the residential rate, and Meralco’s rate schedule raises the residential distribution charge as you use more: ₱0.98 per kWh up to 200 kWh, ₱1.29 up to 300, ₱1.58 up to 400, and ₱2.09 above that.

That’s why Meralco’s “typical household” at 200 kWh paid about ₱14.78 per kWh in August, while my 766 kWh month came to ₱16.01. Add the higher tier and its VAT to ₱14.78 and you land at ₱16.03, within two centavos of my bill.

It’s also why residents in Rockwell report paying far less than we do. When a building buys its power in bulk and passes it on at cost, its residents stop paying the residential tier. Aggregation is how we get a version of that.

Yes, you need one. Every member needs an ERC-approved interval meter that records usage in short intervals, and Meralco’s metering arm installs it. What it costs is still unanswered. We need to know whether it is a straight swap for the old meter at no charge, whether returning the old meter earns a credit, or whether owners pay for the new one. Meralco’s own metering charges are regulated by the ERC, but a supplier can agree to absorb the cost as part of its offer, so it belongs in the negotiation.

According to DMCI’s enrollment card, each member pays the new supplier a deposit equal to the highest monthly bill in the past 12 months. For a 600 kWh unit at ₱16, that’s around ₱9,600, and more if you had a hot summer month. Still unanswered: whether it is refundable when you leave or sell, whether it earns interest, whether it can be paid in installments, and what happens to the bill deposit Meralco already holds from your original account. The deposit is the supplier’s commercial term, so its size and terms can be negotiated too.

The supplier. Meralco’s guide says members get “one consolidated bill from the Retail Supplier” that already includes Meralco’s wire charges. The supplier collects and pays Meralco its share. Meralco still owns the meter, reads it, and fixes outages.

No. The power comes through the same Meralco wires either way. If one plant goes down, the supplier buys from other plants or the spot market. If the supplier itself fails, Meralco steps in as the Supplier of Last Resort. That temporary rate is the spot-market price plus a 5% premium, with a one-month deposit, and it can cost more than Meralco’s regular rate. Your lights stay on, but you might pay more for a while.

No. The ERC rules put no limit on how many users can be grouped, and Meralco’s own examples of a qualifying area include subdivisions, villages, and condominiums. The 2024 rules widened it to any two or more users in the same franchise area. The country’s first residential groups, switched on in June 2026, were 9 households in Blue Ridge A and 13 in Greenhills West. Single-family homes, no condo corporation in the middle.

“One condo corporation per contract” is how the supplier prefers to work. It isn’t in the ERC rules.

Because a bigger, steadier buyer gets a better price, and Acacia is in an unusual position to be one.

Size. Acacia’s residential demand alone is roughly 5,479 kW, about 55 times the 100 kW bar. A block that size is one of the largest any supplier could book in Taguig. One condo corporation’s common areas plus a handful of owners is a small account, and small accounts get standard rates.

A steadier load. Suppliers price on how regular your usage is, not only how much you use. Homes peak in the evening and on weekends, and common-area pumps and lights run all day. Acacia Town Center, which uses most of its power in the daytime, fills in the gap. Put together, the estate’s demand is far steadier than any one condo corporation’s, and steady demand gets a lower rate. That’s why the Town Center belongs in the block.

More bidders. A large block draws serious offers from several suppliers. A small one tends to get a single standard offer.

Less overhead. Onboarding, billing setup, credit checks, and meter scheduling cost a supplier about the same per contract. One tender is cheaper to serve than fourteen, and that saving can go into the price.

One manager already runs everything. Most villages would have to coordinate dozens of separate associations. Every condo corporation in Acacia is managed by the same DMCI property management office, so the organizing work is already in one place. Go one step further and DMCI Homes counts more than 25,000 residents across its Metro Manila communities, which would make a DMCI-wide tender one of the largest residential power deals in the country.

The paperwork has a simple fix: negotiate as one block, sign as separate contracts. All the condo corporations, plus the unit owners who opt in, go out to bid together and get one price. Then each corporation and its unit owners sign their own contract at that price, so no condo corporation is on the hook for another’s bills.

We were told late joiners have to form their own group. That is only true if the contract says so. Ask for an accession clause: anyone in the estate can join the existing contract at the same price during set enrollment windows, say every quarter. Ask also for an exit clause, so an owner who sells or moves can leave without a penalty and get the deposit back. Without these, every round of late joiners becomes a smaller group with a weaker price.

At the briefing, residents asked what rate Rosewood’s common areas are paying, and the answer was that it’s confidential. The rates in the deck are labeled as samples, so we still don’t know what Rosewood actually pays. Supply contracts usually do keep prices private, which is fair. Still, it helps to walk into a negotiation knowing what comparable buyers pay, and a good benchmark isn’t hard to find:

• Rosewood’s condo corporation receives the bill and can share its rate with the managing office that runs both buildings.
• The government tracks the market. In the first quarter of 2026, competitive-market buyers paid ₱5.33 to ₱5.41 per kWh for generation, against ₱6.12 to ₱6.43 for everyone else.
• A tender itself produces the benchmark. Several suppliers pricing the same load tell you what the market will pay.

The deck cited the Data Privacy Act. That law covers personal information about individuals, so it likely doesn’t apply to the price in a contract between two companies.

Not yet. Per DMCI’s enrollment card, the condo corporation runs a bidding once the community’s application is approved. So this is the moment to make sure at least three suppliers are invited, and that MPower’s package is treated as one offer to beat, not the standard. MPower is one of many licensed suppliers. Others include evoEnergi, which powered the first residential groups, Ayala Land’s DirectPower, and Sem-Calaca RES, which belongs to DMCI Holdings, the same group as DMCI Homes.

A short contract lets you rebid sooner if prices fall, and a lot of new generating capacity is on the way. But suppliers usually charge more for short commitments, and every switch takes about 90 days of paperwork and new deposits. The cleanest answer is to ask bidders to price a one-year and a three-year term side by side, and decide with both numbers in front of you.
