What happened

An explosion and fire at CET Bucuresti Vest affected two 110/6 kV transformers used for the plant's internal services and related switchgear. Emergency officials said each transformer held about 30 tonnes of cooling oil; approximately 30 tonnes burned, and the fire spread across three transformers before being extinguished. Romania's energy minister said a 7 MW interruption lasted eight minutes, while the transmission equipment serving western Bucharest continued operating normally. About 2,300 apartment blocks temporarily lost hot water, but no casualties were recorded. Firefighters did not deploy firefighting robots because the equipment was unavailable while undergoing maintenance. A preliminary technical assessment linked the event to a short circuit in a 110 kV cable terminal; the final investigation remained open.
