What is an "electricity supply contract"

An electricity supply contract is the necessary agreement signed between the consumer and DEI to provide electricity to the property. It defines the relationship between the consumer and the supplier (DEI).

What is the advance payment against consumption

The advance payment is not a guarantee, but a partial payment for the electricity that is sold to the consumer, collected later due to technical reasons such as meter readings, bill issuance, and payment deadlines.

What are connection fees

DEI is required by Law 4483/65 (Article 8) to collect connection fees during initial electrification. According to the law, 20% of this fee is retained by DEI as a connection right, while the remaining 80% is deposited in the Bank of Greece as state revenue.
