Starting with the market session of 5 November 2008, GME has become the central counterparty of all transactions in the Green Certificates Market.
GME’s status of central counterparty will completely eliminate the counterparty risk and simplify the administration-accounting formalities arising from participation in a regulated market.

HOW TO OPERATE:
Before the market session

To participate in the market, purchasing Market Participants are required to make a single payment to GME as a guarantee deposit covering all their purchases. The trading system will accept purchase orders only if they are entirely covered by the available deposit.

During the market session

In purchase and sale orders, prices must quoted NET OF VAT.
The system will automatically compute the value of the transaction including VAT, if applicable, updating the available deposit during the session, confirming the executed transactions and carrying out administration-accounting tasks.

After the end of the market session

a) Sellers must issue a single invoice to the purchaser GME;
b) Purchasers will receive a single invoice from GME.
The provisions governing the operation and management of the Green Certificates Bilaterals Registration Platform (PBCV) will remain unaltered.

The Technical Rules define the modalities for participating in the Green Certificates Market, as well as the rules for notifying the amount of the cash deposit and the conventional price.

Ordinary sessions

The last session of the green certificates market was held on 28 June 2016 from 9.00 to 12.00.
