Meralco moves to formalize Cagbalete microgrid operations

From AB Capital's The Opening Bell: Three Moves

Event

Meralco (MER) is seeking Energy Regulatory Commission (ERC) approval to operate Cagbalete Island as a microgrid for 20 years, following its December 2025 energization. The 2.8MWp solar-plus-storage system serves 1,192 households at a P39.17/kWh full-cost recovery rate, of which P27.17/kWh is covered by a subsidy under the universal charge for missionary electrification (UCME). Approval would allow MER to begin collecting subsidies outstanding since January.

View

The project is small relative to MER, with just 1,192 households vs 8 million+ customers. However, MER has been providing the service without receiving the UCME subsidy since January, so approval should allow it to recover costs already incurred, albeit with limited earnings impact. More importantly, Cagbalete demonstrates a structure for serving hard-to-reach areas without MER bearing the full cost of off-grid supply.

Catalyst

Regulatory developments remain the key swing factor for MER, with the market still focused on the system-loss issue and upcoming rate reset. Against this backdrop, ERC approval would provide a small positive read-through on MER's ability to recover costs through established regulatory mechanisms, while further microgrid approvals would strengthen the case for this to become a repeatable opportunity.

Action

We see this as mildly positive for MER, with the near-term benefit coming from recovery of outstanding subsidies rather than earnings growth. The longer-term opportunity is more relevant: successful replication could allow MER to expand its regulated footprint into underserved areas while limiting its exposure to the high cost of off-grid supply.
