The legal person holding a generation license shall be issued by EMRA with a "Renewable Energy Resource Certificate” (RER Certificate) for the purpose of identifying and monitoring the resource type in trading electricity generated from renewable energy resources in the domestic and international markets.
A Renewable Energy Resource Guarantee Certificate (RER-G certificate) is issued by the legal entity authorized by EMRA in order to monitor and prove that the electrical energy supplied to consumers is produced from renewable energy sources and to enable consumers to document and exported.
In the RER-G system, the RER-G certificate issuer is EXIST. EXIST is responsible for establishing, operating and managing the registration database with the RER-G system. One RER-G certificate is issued for each 1 MWh of certified production amount. This certificate is valid for 12 months from the end date of the production period of electrical energy produced from renewable energy sources.
RER-G system users consist of generation license holders and supply license holder legal entities that have signed a RER-G system participation agreement with EXIST. Suppliers producing unlicensed electricity cannot be users of RER-G system. Multiple-source electricity generation license holders can participate in the RER-G market if all of the energy resources used in the facility are renewable.
License holder legal entities wishing to join the RER-G system are required to register with EXIST and open an account in the EXIST registration database. In order to register the relevant legal entities, they must have completed the legal entity registration according to the relevant articles of the Electricity Market Balancing and Settlement Regulation. In addition, the generation license holder legal entities must have accepted at least one or one unit of the generation facilities and completed the records regarding the settlement-withdrawal units associated with them at the time of the application. Legal entities wishing to join RER-G are required to sign a participation agreement and a participation commitment with EXIST.
It is registered in the RER-G system for each calendar year. Production facilities whose RER-G system participation status is inactive during the year cannot rejoin for the same calendar year.
RER-G document trading can be carried out in the organized RER-G market independently of the energy supply, together with the energy supply or in the RER-G bilateral agreement market, independently of the energy supply.
Organized RER-G market is the market organized and operated by EXIST, where RER-G certificate is bought and sold among market participants. Matches in this market are carried out by the continuous trading method, where the offers can be matched immediately after they are included in the bid book and the commercial transaction can take place. Contracts to be opened in the continuous trading method are traded during the session. In each transaction concluded in the organized RER-G market, EXIST becomes a party to the relevant market participant.
EXIST receives guarantees from the market participants regarding the financial risks that may arise regarding the payments of the transactions made within the scope of the organized RER-G market transactions.
Transactions can be canceled by EXIST upon the application of a market participant who is a party to the transaction or ex officio. In case of errors arising from computer, software or other technological infrastructures originating from EXIST, or in the event that offers and transactions aimed at obtaining market-distorting or unfair benefits are detected, all or part of the offers and/or transactions in the Organized RER-G market are canceled.
Organized RER-G market participants can appeal only if there is an error originating from EXIST in their notifications regarding their commercial transaction approvals. The objection does not eliminate the payment and other obligations of the market participant.
