# Philippines electricity supply and grid instability > Live situation record from CLSTR: https://clstr.news/situations/philippines-electricity-supply-and-grid-instability > Updated: 2026-08-10T02:48:13.000Z. Sources: 4. Developments: 2. The Philippines is experiencing significant electricity supply instability, characterized by localized cooperative failures and broader national grid alerts. Initially, specific electric cooperatives reported severe reliability issues. In Catanduanes, generator failures and unsettled subsidies led to daily brownouts lasting up to eight hours. In Albay, the struggles of the Albay Electric Cooperative sparked national debates regarding privatization versus rehabilitation. Meanwhile, in Palawan, residents protested for reliable power despite official performance ratings. These issues are compounded by systemic challenges, including high system-loss allowances for cooperatives and aging infrastructure. This instability escalated to the national level as the National Grid Corp. of the Philippines (NGCP) issued red and yellow alerts for the Visayas and Mindanao grids. The shortages were driven by the unavailability of major coal-fired units and forced outages at several power plants, some of which have been out of service since 2021. At the height of the shortage, outages and derated capacities removed approximately 909.8 MW from the grid, representing nearly 40 percent of available capacity. ## Timeline ### 2026-08-10: Philippines power grids face alerts due to supply shortages The Philippines' Visayas and Mindanao grids faced red and yellow alerts on August 10 due to power shortages, plant outages, and limited electricity imports, raising the risk of rotational brownouts. 2 sources. https://clstr.news/cluster/philippines-power-grids-face-alerts-due-to-supply-shortages ### 2026-08-02: Philippines electric cooperatives face reliability crisis and push for reform Philippine electric cooperatives face chronic brownouts, high system‑loss charges and a reform debate, prompting rallies and a presidential proposal to cut fees. 2 sources. https://clstr.news/cluster/philippines-electric-cooperatives-face-reliability-crisis-and-push-for-reform --- Cite as: Philippines electricity supply and grid instability.
