The Energy Regulatory Commission (ERC) has imposed new market share limits for power generation companies in 2026, capping ownership at 30% of any grid's installed capacity and 25% of the national total.
The limits aim to foster fair competition and protect consumers from excessive prices, the regulator said. For the national grid, the maximum installed generating capacity is set at 28,197,045 kilowatts (kW), broken down into 20,422,906 kW for Luzon, 3,478,324 kW for Visayas, and 4,295,915 kW for Mindanao.
Under the cap, no generation firm may own more than 7,049,261 kW nationwide, with regional ceilings of 6,126,842 kW for Luzon, 1,043,497 kW for Visayas, and 1,288,775 kW for Mindanao.
"Healthy competition in the power sector is essential to ensuring reliable electricity supply and protecting consumers from unreasonable prices," said ERC Chair Francis Saturnino Juan in a statement. He added that the 2026 resolution allows the ERC to more accurately reflect actual operating capacities of power plants nationwide while maintaining fair and transparent competition.
The caps apply to all generation companies operating in the Philippines, as the energy sector continues to expand and modernize.
