Developments: 2. In late July 2026, Montenegro’s state utility EPCG announced that the Perućica hydroelectric plant would be taken completely offline for its scheduled August refurbishment, with draining, cleaning and capital works planned from 30 July through 30 August and a restart expected on 1 September. A few days later, on 1 August, EPCG reported an unexpected loss of external power supply at the Pljevlja thermal power plant due to a high‑voltage transmission fault. The plant was taken offline, but coordinated safety actions kept the national grid stable and electricity supply uninterrupted. EPCG said it would cool the thermal block, conduct technical analyses and decide on a restart, while noting the broader challenges of reduced nuclear generation and unfavorable hydrological conditions. Together, the snapshots show Montenegro managing both planned hydroelectric maintenance and an unplanned thermal plant outage, with the utility emphasizing grid stability throughout the period. ## Timeline ### 2026-08-01: Pljevlja Thermal Power Plant Outage Keeps Montenegro Grid Stable A transmission fault shut down Montenegro's Pljevlja plant, but EPCG says the grid stays stable and safety systems worked; restart pending technical checks. 4 sources. https://clstr.news/cluster/ni-serbia-power-outage-planned-for-august-3-2026 ### 2026-07-28: Perućica Hydroelectric Plant Shut Down for August 2026 Maintenance Perućica hydro plant in Montenegro will be offline 1‑30 August 2026 for annual maintenance, with preparations starting 30 July; the shutdown allows capital projects, and EPCG warned nearby residents of safety‑h 2 sources. https://clstr.news/cluster/peruica-hydroelectric-plant-shut-down-for-august-2026-maintenance --- Cite as: Montenegro power plant disruptions.
