Manila: The Energy Regulatory Commission (ERC) is advocating for comprehensive reforms aimed at upgrading grid standards, enhancing system reliability, and facilitating the integration of renewable energy within the Philippines.
According to Philippines News Agency, the ERC announced in a statement that the Philippine Grid Code (PGC) 2026 Edition is set to modernize the country's transmission infrastructure. This modernization will be achieved through updated technical standards, robust reliability mechanisms, and provisions for emerging technologies. The initiative aims to create a more resilient and future-ready grid, especially in light of the increasing share of renewable energy sources.
The new Code proposes significant updates to enable the grid to accommodate variable renewable energy (VRE) and a spectrum of emerging energy technologies. These technologies include energy storage systems such as battery energy storage systems (BESS), pumped-storage hydropower, compressed air energy storage, and flywheel energy storage. The Code also covers wind power plants (both onshore and offshore), solar photovoltaic (PV) plants-including ground-mounted and floating systems-and nuclear power facilities.
Furthermore, the proposed Code incorporates new technical requirements for solar PV plants integrated with BESS using grid-forming (GFM) inverters. Standards applicable to other BESS installations utilizing GFM inverter technologies are also included, all aimed at enhancing grid stability and system response.
Key reforms under the proposed changes include strengthened cybersecurity requirements, updated grid planning standards, expanded reserve and reliability mechanisms, and new technical requirements for integrating renewable energy and energy storage systems. The Code also introduces innovations like Fast Frequency Reserve, grid-forming inverter standards, and advanced provisions for energy storage integration.
ERC Chairperson and Chief Executive Officer Francis Saturnino Juan emphasized the strategic importance of these reforms, stating, "This is not just a technical update, it is a strategic reform that prepares our power system for the future. The Philippine Grid Code (PGC) 2026 Edition is designed to ensure that as we bring in more renewable energy and advanced technologies, our grid remains stable, reliable, and secure."
The draft Code is the result of extensive consultations conducted nationwide in January 2026, involving stakeholders from Luzon, Visayas, and Mindanao. These consultations were coordinated with the Institute of Integrated Electrical Engineers of the Philippines and the Interim Grid Management Committee under the Energy Transition Project, in partnership with the Energy Transition Partnership-United Nations Office for Project Services.
Juan further noted, "Through the PGC 2026 Edition, we are building a grid that is not only resilient but also capable of supporting cleaner and more sustainable energy sources."
To ensure stakeholder engagement and feedback, the ERC will hold public consultations on July 15 and 17. These consultations are intended to provide a platform for stakeholders to raise concerns, offer recommendations, and contribute to the finalization of the updated Grid Code.
