There are mainly two types of invoices:

• Fixed tariffs: They offer a fixed price per kilowatt-hour (kWh) for the duration of the contract, usually 12 or 24 months. They are ideal for those who want predictability in their bills.

• Variable tariffs: The price per kWh varies according to fluctuations in the wholesale energy market. They may offer lower prices when the market is favourable, but carry the risk of increases during periods of high prices.

The indexation clause is a mechanism that allows the price of electricity to be adjusted in line with fluctuations in the wholesale market. When market prices increase, the charge to the consumer may increase, and vice versa.

You can use price comparison tools, such as the RAEAY (Waste, Energy and Water Regulatory Authority) tool on energycost.gr, to compare the available tariffs and choose the most suitable one for your needs.

The process of switching provider is simple and without a power cut. All you need to do is sign a contract with the new provider and provide the necessary documents. The new provider takes care of updating the previous provider and the switching process.

No, there is no cost to the consumer for switching provider.

Regulated charges are costs imposed by the state and relate to the use of the electricity transmission and distribution network, Public Utility Services, the Special Emission Reduction Levy (SRL) and other charges. These charges are the same for all consumers, irrespective of the supplier.

To ensure lower charges, you can:

• Choose plans with a consistency discount for paying bills on time.

• Combine electricity and gas supply with the same provider for extra discounts.

• Choose tariffs without an indexation clause for more stable charges.
