8.a Revenue from sales and services - €77,366 million

An electricity/gas supply agreement signed with an end users includes a single performance obligation (sale and transport of the commodity) because the Group has determined that the contract does not provide distinct goods/services and the promise is satisfied by transferring control over the commodity to the customer when it is delivered at the point of delivery. In order to determine the nature of the promise included in such contracts, the Group carefully analyzes the facts and circumstances applicable to each contract and commodity.
However, the Group considers that the performance obligation provided for in a repetitive service contract, such as a supply or transport contract for the provision of electricity/gas to end users is typically satisfied over time (because the customer simultaneously receives and consumes the benefits of the commodity as it is delivered) as part of a series of distinct goods/services (i.e., each unit of commodity) that are substantially the same and have the same pattern of transfer to the customer. In these cases, the Group applies an output method to recognize revenue in the amount to which it has a right to invoice the customer if that amount corresponds directly with the value to the customer of the performance completed to date.

The network connection fees received from customers for connecting them to the electricity/ gas distribution networks require a specific Group assessment to take into consideration all terms and conditions of the connection arrangements.
This assessment is intended to determine whether the contract includes other distinct goods or services, such as for example, the right to obtain ongoing access to the infrastructure in order to receive the commodity or, when the connection fee is a “non-refundable up-front fee” paid at or near contract inception, a material right that gives rise to a performance obligation.
In particular, in some countries in which the Group operates, it has determined that the nature of the consideration received represents a “non-refundable up-front fee” whose payment provides a material right to the customer. In order to determine if the period over which this material right should be recognized extends beyond the initial contractual period, the Group takes into consideration the applicable local legal and regulatory framework applicable to the contract and that affect the parties.
In such cases, if there is an implied assignment of the material right and an obligation from the initial customer to the new customer, the Group recognizes the connection fee over a period beyond the relationship with the initial customer, considering the concession terms as the period during which the initial customer and any future customer can benefit from the ongoing access without paying an additional connection fee. As a consequence, the fee is recognized over the period for which the payment creates an obligation for the Group to make the lower prices available to future customers (i.e., the period during which the customer is expected to benefit from the ongoing access service without having to pay an “up-front fee” upon renewal).

The construction contracts typically include a performance obligation satisfied over time. For these contracts, the Group generally considers it appropriate to use an input method for measuring progress, except when a specific contract analysis suggests the use of an alternative method that better depicts the Group’s performance obligation fulfilled at reporting date.
