ewz is not liable for direct or indirect damage resulting from power outages, regardless of the cause of the outage. Liability is governed by the Regulations on the operation of the distribution grid and energy supply.
According to these regulations, our electricity customers must ensure that no people or property are endangered during a power outage. This includes when the electricity fails unexpectedly. You must therefore protect your technical systems from power outages and power fluctuations yourself.
Power outages can result from scheduled work or unforeseen events. ewz provides advance notice of planned interruptions, for example in the event of maintenance or construction work. Unplanned outages occur, for example, when cables get damaged during construction work.
Current fault reports for the ewz supply area can be found at ewz.ch/störung and on ewz’s X channel, where ongoing updates are provided on causes and the progress of repairs.
