Electricity supplies in rural areas can be a problem in Crete, made worse by the influx of visitors during the June and October summer holiday season.
During this summer period, the Electrical Company, may divert supplies to the main beach front towns, and restrict supplies, or cut off supplies altogether, to the inland rural areas. These power shortages are usually only for a few hours, but may extend to over a day.
Likewise, during the winter months, power supplies are still often interrupted by stormy weather.
With this in mind, you may wish to consider the installation of a ‘partial-house standby generator’ to supply power to the essential areas of the property (e.g. fridge/freezer, lighting and small power).
This is a decision which should be made early on, as the electrician will need to design the wiring to accommodate this requirement when wiring the property.
