2025 IGC and MSL (initial setting)_ERC

The Energy Regulatory Commission (ERC) has released the initial setting of the installed generating capacity (IGC) and the market share limitation (MSL) per grid and national grid for this year as a way to promote free and fair competition in the power industry.

In a statement on Monday, March 17, the ERC said it has issued the 2025 IGC and MSL per grid and national grid through the ownership/control and maximum stable load (Pmax) data, which is the maximum net output in megawatt (MW) that a generating unit can maintain.

IGC and MSL are set yearly by the ERC and may be adjusted depending on the maximum capacity of the generation facilities.

According to the regulator, the national IGC has been set to 27,096 MW, with an MSL of 6,774 MW. The installed capacity for Luzon is set at 19,419 MW and is approximately eight percent higher than last year’s figure, with a market share cap of 5,825.9 MW.

For Visayas, the IGC for this year is at 3,383.9 MW, with a market share limit of 1,015.2 MW, while Mindanao is at 4,292.6 MW and a 1,287.8 MW MSL.

This initial setting is under Section 45 of Republic Act (RA) No. 9136 or the Electric Power Industry Reform Act of 2001 (EPIRA), which states that any company or related entity is prohibited to own, operate, or control more than 30 percent of the IGC per grid and or 25 percent of the national IGC.

“Certain industry developments—such as the change in ownership of some large generation facilities—have not been reflected in the data set,” the ERC said.

“Once ready and available, the 2025 IGC and MSL shall be adjusted accordingly.”

The regulators further noted that Ramon S. Ang-led San Miguel Corp. (SMC) has one of the highest capacity in the generation sector, with a national market share of 6,079.6 MW in 2025.

Aboitiz Equity Ventures Inc. came in second with 5,894.5 MW, while First Gen Corp. followed with 3,583 MW.

Manila Electric Co. (Meralco) has a national market share capacity of 1,467.3 MW, while Ayala Corp. has about 1,431.3 MW.

“All individuals and entities subject to the MSL are reminded to strictly comply with the prescribed limits and promptly report to the ERC within 15 days of exceeding these limits from the start of occurrence, including the reasons for non-compliance,” the regulator concluded.
