What happened

A power outage affected the left bank of the Vltava in Prague, particularly the Prague 5 and Prague 6 districts. Pražská energetika (PRE) said the cause was a technical problem at two substations. The company's spokesperson told the Czech News Agency (ČTK) that the outage should not last long. Firefighters reported responding to several incidents in which people were rescued from lifts during the outage. The source does not give the substation names, the fault type, the number of customers affected, or the time the supply was restored. The article is a machine translation of a Czech original and had not been fully reviewed when published.

Contributing factors

The source attributes the outage to a technical problem at two substations. No further cause is given.

Lessons learned

  1. Operators of substations serving dense urban areas should check that a fault at one station can be isolated without cutting supply to a whole district.
  2. Distribution companies should publish early, updated information on affected areas and expected restoration times during outages.
  3. Building owners and emergency services should plan for lift rescues and the needs of vulnerable residents when power fails in tall buildings.
