Who is my electricity network operator?

The country is divided into a series of block letters. In the unlikely event that a power cut rota is implemented in case of an energy shortage, most people in the same block letter will be without power at the same time.

Unless you move premises, your block letter will remain unchanged. It is determined by where your premises is located and how the property is connected to the power grid. You also can find your block letter on your bill.
