Keep Resolution 34. The 600/150 ceilings were a 2016 proxy for grid security; the System Impact Study tests the real limit — N-1 and thermal — at each site. Reliability now rides on the ancillary-service restudy, not the MW number.
Keep Resolution No. 34, Series of 2026. It removes the per-unit capacity limit that Resolution No. 08, Series of 2016 set at 650 MW for Luzon and 150 MW for Visayas and Mindanao, and that Resolution No. 18, Series of 2017 clarified to 600 MW as capacity injected to the grid; the press printed 600/150 as the previous limits. One number for every site is a blunt proxy: it binds a plant at a strong node as hard as one at a weak node.
The replacement test is the right one. Every proposed grid-connected plant now needs a System Impact Study from NGCP or an accredited third party, so the connection does not degrade the grid under N-1 contingency and thermal limits, and the Transmission Network Provider weighs Transmission Development Plan provisions for large plants. That is the actual security question, asked per site instead of guessed per grid.
The cost of bigger units is reserve. One large machine raises the largest single contingency, so the System Operator must restudy ancillary service levels in the ASPAs, the Reserve Market, the Philippine Grid Code, and the Ancillary Service Procurement Plan, subject to ERC review. That restudy, not the MW ceiling, is now where reliability is decided. ERC should sequence rather than re-cap: hold SIS approvals for units above the old ceilings until the System Operator files the restudied levels.
The ERC press printed effectivity after Official Gazette or newspaper publication. No consumer-rate or plant-cost peso is printed; the press itself says actual price effects depend on project development, grid readiness, and market conditions.

critique
Mira Mabini says keep Resolution 34 because the 600/150 ceilings were a 2016 proxy for grid security, the System Impact Study tests the real N-1 and thermal limits at each site, and reliability now rides on the ancillary-service restudy. I agree on keeping it. Two points need correcting. The 2016 resolution printed 650 MW for Luzon and the 2017 clarification printed 600 MW injected to the grid, so the ceilings are not one 2016 number, and the printed resolution does not call them a security proxy. Reliability rides first on the System Impact Study, because the restudy comes after the lift and is subject to ERC review.

critique
Mira argues that Resolution No. 34 should take effect now because a System Impact Study applies N-1 and thermal limits at each site, while reliability shifts to the ancillary-service restudy. That conflates a connection study with system-wide readiness for a larger single contingency. Resolution No. 34 itself directs the System Operator to restudy ancillary-service levels and reflect the new largest unit in the Philippine Grid Code and Ancillary Service Procurement Plan, subject to ERC review. Keep the 600 MW and 150 MW ceilings until those approved changes are posted, while allowing studies for larger proposals to proceed.

amendment
Mira Mabini argues that the Energy Regulatory Commission should keep Resolution No. 34, Series of 2026 because the former per-unit ceilings were a proxy for grid security that is now tested at each site by a System Impact Study under N-1 and thermal limits, placing reliability on the ancillary-service restudy rather than a fixed megawatt number. That core mechanism is sound, though the record should first distinguish Resolution No. 08, Series of 2016 (650 MW per unit for Luzon and 150 MW for Visayas and Mindanao) from Resolution No. 18, Series of 2017 (which clarified the limit as 600 MW injected to the grid for Luzon and 150 MW for Visayas and Mindanao, the figures cited by ERC press, Philstar, Bilyonaryo, and Inquirer). In addition, while Resolution No. 34 directs the System Operator to restudy Ancillary Service Procurement Agreements, the Reserve Market ratio, the Philippine Grid Code, and the Ancillary Service Procurement Plan subject to ERC review, those amended Grid Code and plan texts are not yet printed. Mira Mabini's argument should therefore be amended to sequence implementation: keep the per-unit cap removal and NGCP or accredited third-party System Impact Study screening now, but require the System Operator's ancillary-service restudy to be filed with the ERC before the first generating unit above the former ceilings connects.
