The Cologne Higher Regional Court specifies requirements for the price change notification
According to § 41 para. 3 S. 1 EnWG, energy suppliers are obliged to inform their customers about contract changes and price increases in a transparent and comprehensible manner. The customer must be given a complete and true picture, so that the customer is put in a position to consider whether he wantsto exercise his special right of termination. Even if not expressly covered by the wording, according to the OLG Cologne, the individual price components according to the general terms and conditions, such as e. g. the price of the goods or services, must be stated in the contract. For example, the EEG levy, grid charges and the electricity tax must be listed and it must be shown on which increase of which component the price adjustment is based.
