Romania: Investigation over Bucharest power outage, SEE Energy News
In order to establish the causes that led to the damage at the Fundeni transformer station, which caused a power outage in Bucharest on 12 January, the National Energy Regulatory Authority (ANRE) announced that it has launched an investigation at electricity transmission system operator Transelectrica.
The electricity supply was interrupted in sector 2 of Bucharest, following an incident at the Fundeni transformer station. The incident took place at 11:14, and by 11:40, electricity supply for all consumers was restored. The statement from Transelectrica said that in the 220/110 kV Transformer Power Station Fundeni, a malfunction was registered that affected the voltage level of 10 kV from which the consumption area adjacent to Fundeni station is supplied.
Last November, a breakdown at the same station led to a power outage that affected 100,000 inhabitants of the Romanian capital.
Last week, a power outage in part of Romania is to blame for a drop in frequency in Europe’s electricity system on Friday afternoon. According to Transelectrica, northwestern part of Romania was left without electricity at around 15:00, in some places for up to an hour and a half, while in other parts of the country, the voltage dropped to even 90 V. The European Network of Transmission System Operators for Electricity (ENTSO-E) confirmed that the frequency dropped to 49.745 Hz on Friday afternoon. Otherwise, a frequency of 50 HZ is required for normal network operation. European electricity operators managed to stabilize the network after an hour.
