KEY DEADLINES
Effective immediately after publication in a newspaper of general circulation.
Next review/adjustment may occur on or before 15 March 2027.
TAKEAWAY
Entities must ensure compliance with the new MSL thresholds for 2026 and monitor for future adjustments.

KEY POINTS
Scope: Applies to all persons or entities covered by the Market Share Limitation (MSL) per Grid and National Grid under Section 45(a) of EPIRA.
Requirements: Sets the Installed Generating Capacity (IGC) and Market Share Limitation (MSL) per Grid and National Grid for 2026.
Thresholds: MSL set at 30% per grid (Luzon, Visayas, Mindanao) and 25% for the National Grid.
2026 IGC and MSL Values: Luzon – 20,422,806 kW (MSL: 6,126,842 kW); Visayas – 3,478,324 kW (MSL: 1,043,497 kW); Mindanao – 4,295,915 kW (MSL: 1,288,775 kW); National – 28,197,045 kW (MSL: 7,049,261 kW).
Deadline: The set IGC and MSL shall remain in effect until the next adjustment, which may occur on or before March 15, 2027, and every year thereafter, or as necessary.
Compliance Obligation: Covered entities must ensure their ownership, operation, or control of installed generating capacity does not exceed the prescribed MSL per grid and national grid.
Mechanism Introduced: Use of Maximum Stable Load (Pmax) as the standard basis for determining the maximum capacity of generation facilities in the calculation of IGC.
Enforcement: The resolution takes effect immediately upon publication in a newspaper of general circulation and shall be strictly enforced until superseded or amended.
