Offer terms
Full offer text
The “Fisso 2.0” offer has a fixed price and is available to all customers who hold sites for household use. The natural gas commodity price consists of: a) a consumption charge (fixed price of €0.6186/SMC), and b) an annual charge of €263.88/year/PdP. The offer provides for a monthly installment calculated based on annual consumption over the previous 12 months. The monthly installment is subject to adjustment against the amounts actually due under this offer. At the end of the 12-month supply period, or if supply ends for any reason, Ermes Gas & Power will calculate the difference between the amounts paid by the customer and those actually due under this offer based on the customer's actual consumption, and will debit or credit the corresponding amount paid in deficit or excess.
Supply will begin on the first available date communicated by Ermes Gas & Power to the Customer. Ermes Gas & Power’s performance of the contract is subject to the condition that the Customer is not suspended for non-payment when Ermes Gas & Power requests activation of the supply from the Distributor. Upon concluding the contract, the Customer grants Ermes Gas & Power, which accepts, an exclusive and irrevocable mandate without representation for the entire term of the contract, authorising it, after the contract is completed, to manage in its own name and in the Customer’s interest the contract for the provision of the transport service, including receipt and management of meter and consumption data, as well as the contract for managing the connection of the sites. For activities requested by the Customer relating to services within the Distributor’s remit, Ermes Gas & Power will charge the Customer amounts equal to the charges provided for by the applicable regulations, as well as any charges invoiced to Ermes Gas & Power by the Distributor, plus a fee of Euro 45,45 excluding VAT.
The offer provides for a monthly instalment calculated based on the annual consumption for the previous 12 months. The monthly instalment is subject to adjustment against the amounts actually due under this offer. At the end of 12 months of supply, or if supply ends for any reason, Ermes Gas & Power will calculate the difference between the amounts paid by the customer and those actually due under this offer based on the Customer’s actual consumption, and will charge or credit the corresponding amounts paid in excess or short. 100% of the CO2 emissions from the combustion of the Natural Gas covered by this offer will be offset through the purchase of carbon credits certifying participation in international energy-efficiency projects implemented in different parts of the world that reduce or avoid the release of greenhouse gases into the atmosphere.
