  • Generators

What does this accounting service option provide?

This accounting service option is offered to a generator customer whose site is connected to the Public Transmission System (PTS), who holds a feed in tariff contract for part of the generation.

It is offered to generation sites whose production benefits partly from a feed in tariff contract concluded as follows:

  • either one of the generation unit(s) benefits from a feed in tariff contract, whereas the other Generation Unit(s) do not;
  • or a generation unit is entitled to a feed in tariff contract for only part of its generation based on the application of a ratio.

How do I subscribe?

The contracting steps are as follows

If a ratio[1] is mentioned in your feed in tariff contract, you are required to send this to RTE, putting the Mandatory Purchaser in a copy of your notification. Otherwise you need to ask RTE to install RTE meters to enable individualisation of energy flows relating to the group(s) benefiting from a feed in tariff contract.

You are then required to:

  • contract with RTE an Optional Services Contract (Contrat de Prestations Annexes) in order to subscribe to the "accounting service : Option D”, and choose the billing terms (cheque, wire transfer or direct debit).
  • accept the CART update proposed by RTE, to take into account the new meters
  • designate the Mandatory Purchaser’s balance responsible party for the Generation Unit(s), providing an attachment agreement (Annex C7) in accordance with the MA-RE Terms and Conditions (Section 2).
  • inform your site’s balance responsible party of the subscription to the accounting service.
  • designate a Scheduling Agent for the Generation Unit(s) in PO, providing an attachment agreement (Annex C6) in accordance with the MA-RE Terms and Conditions (Section 1).
  • if relevant, include the Generation Unit(s) in a Balancing Entity (BE) as part of the Balancing Mechanism.

[1] Applied to the generation of a group in MW.

Note: if you have several feed in tariff contracts for your site’s Generation Units, you subscribe to as many services as required.


To subscribe to this option:

  • you need to hold a Generator CART contract.
  • you must have a feed in tariff contract for a part of the generation of the site.

The minimum duration of subscription for the service is one year.

If the service is terminated, RTE shall, at its cost, proceed with the removal of the metering equipment associated with the service previously subscribed to.

The fees consist of:

  • A fee for management costs on subscription to the service: 6720 Euros.
  • Of a set annual management fee: 720 Euros/year.
  • If applicable, a fee for management costs related to the modification/reconfiguration of the service. This includes the balance responsible party change: 2560 Euros per modification/reconfiguration.

These fees are billed semi-annually.

In addition to this, metering fees are added where relevant, as provided for in the TURPE:

  • Annual metering component HV-B per meter: 3061.92 Euros
