INVOICING MGP AND MI
Given W the week in which the electricity being traded on the MGP and MI (MI-A and MI-XBID) has been delivered, the billing period of the related payoffs is the calendar month in which these items were financially regulated.
For each invoicing period, within the terms established in the Technical Rules, GME makes available:
- for each participant that is a debtor (other than the PA Participant), one or more proforma invoice communications with the sum of the economic amounts of the transactions carried out on the MGP and on the MI related to:
- sales concluded by GME with a unit price greater than or equal to zero, financially settled in the reference calendar month;
- services provided by GME following sales made by Participants with a negative unit price, financially settled in the reference calendar month.
- for each participant that is a creditor, one or more proforma invoice communications, containing all the information necessary for Participants to prepare the invoices to be issued to GME. In particular, these communications show the sum of the economic amounts of the transactions carried out on the MGP and on the MI related to:
- sales concluded by participants with a unit price greater than or equal to zero, financially settled in the reference calendar month;
- services provided by participants following purchases made by them with a negative unit price, financially settled in the reference calendar month.
Within the terms defined in ME Technical Rules n. 08, the GME:
- issues the invoices related to GME's sales with a unit price greater than or equal to zero and the invoices related to the services provided for the sales of Market Participants with a negative unit price, concluded on the MGP and on the MI, financially settled in the same calendar month;
- sends the PA Participants the invoices related to the sales made with a unit price greater than or equal to zero and the invoices related to the services provided, as consequence of all sales by the participants with a negative unit price, concluded on the MGP and on the MI;
- receives from each participant the invoices payable related to purchases made with a unit price greater than or equal to zero and the invoices related to the services received resulting from all purchases by Market Participants with a negative unit price, concluded on the MGP and on the MI, financially settled in the same calendar month.
The exchange of communications related to the proforma invoices and invoices between GME and Market Participants takes place through the provision on the "SetService" IT platform. Under the conditions set forth by the legislation in force from time to time on electronic invoicing and of the related implementing provisions, the invoices are transmitted through the so-called Sistema di Interscambio (SDI).
