Manila: All prospective variable renewable energy (VRE) plants with at least 10 megawatts (MW) capacity must now integrate an energy storage system (ESS) under new rules from the Department of Energy (DOE). The requirement follows Department Circular No. DC2026-02-0008, which updates the ESS policy framework.

According to Philippines News Agency, the updated framework advances the government's commitment to a just energy transition by supporting ESS deployment and ensuring its systematic integration in both grid-connected and off-grid areas. This integration aims to enable higher renewable energy penetration while preserving power quality and system reliability.

The DOE added that ESS installations are encouraged to include grid-support capabilities, including but not limited to grid-forming (GFM) inverters that help stabilize voltage and frequency. These capabilities are intended to mitigate the inherent variability of renewable output, enable optimized dispatch, minimize generation losses, and strengthen the grid's ability to maintain power quality, reliability, and overall system stability.

Energy Secretary Sharon Garin emphasized that energy storage is not only about storing surplus energy but also about strengthening the grid's capability to absorb more renewable energy while maintaining reliability. She highlighted that the policy ensures ESS integration becomes part of system planning and project development, supporting better outcomes for consumers.
