Auctions of GOs by AIB members
In some countries, renewable electricity that has benefited from financial support is not awarded with GOs. Another option is to issue GOs for supported electricity but that these GOs are auctioned in order to offset the costs of the support system.
Italy - Gestore dei Servizi Energetici (GSE)
In Italy, GOs auctions were introduced for the first time in 2013, by the Energy Regulator Resolution. Auction revenues are used to reduce the cost sustained by electricity consumers to promote the renewable energy in Italy.
According to the National Legislation, GSE calculates the number of GOs related to the electricity produced and injected into the grid in order to define the quantity of GOs to be offered during the auctions. The electricity taken into account is the one produced by the RES power plants that benefit from the “dedicated withdrawal” by GSE and which grant feed in tariffs.
Every year, five auctions are organized by GSE. GOs are differentiated according to the type of plant and production period.
Approximately five days before auction session, GSE publishes on its website: the amount of GOs to be auctioned and the initial auction-bidding price determined by GSE based on GOs market price in Italy. In this way, market operators can start sending purchasing-bid. At the end of the auction session, GSE publishes, in aggregated form, the number of certificates sold (split by source and production period), minimum and maximum price and the average price weighted by the registered volumes.
More information like the rules for participation, the calendar and many other information on the auctions are available in this document (in Italian) about the Italian Auction Procedure.
Luxembourg - Institut Luxembourgeois de Régulation (ILR)
In the second half of 2018 ILR started issuing GOs for electricity produced from renewable energy sources from production devices currently receiving production support in Luxembourg.
Those GOs are being periodically auctioned on the ILR auctioning platform.
Auction revenues are used to decrease the cost of the public support scheme.
Auctions take place on a quarterly basis separately for wind onshore, solar and solid biomass. More information like the auction calendar, volumes, results as well as concerned production devices are available on https://goauction.ilr.lu/

France – European Energy Exchange (EEX)
EEX has started auctioning GOs in September 2019, on behalf the French Minister for an Ecological and Solidary Transition, auctioning GOs for electricity produced from renewable energy sources from production devices currently receiving support in France. To optimize the allocation of GOs, EEX has designed a specific algorithm, to enable GO buyers, to submit orders by specifying, a region, a technology and even indicate a production device as a preference. Moreover, the auction is cleared and secured by our clearing house, the European Commodity Clearing (ECC). The auction revenues are dedicated to a special fund acting for energy transition.
Auctions take place monthly at the same time for all energy sources. The quantity of GOs to be auctioned each month is defined by the French State. See here more information like auction calendar, volumes, results and production devices.
Auction participants need to open an account in the French registry. For more information, related to the GO auction system or the admission process to become a member, please contact email@example.com.
Portugal - REN
In Portugal, the auctions of guarantees of origin (GOs) from power plants that benefit from price or investment support began in July 2021. As provided for in the legal framework established by DL No. 141/2010, as amended by DL No. 60/2020, the GOs concerning the generation of electricity from renewable sources that benefit from support must be delivered to the Directorate-General of Energy and Geology (DGEG), which transacts them through auctions. The net income of these auctions must be subsequently deducted from the overheads related to the acquisition of electricity from renewable energy sources, thus reverting to consumers.
Participation in the auctions is open to all entities, both domestic and foreign, requiring previous registration with OMIP, S.A., which is the entity responsible for the execution of the auction, and with REN-EEGO, which ensures the physical settlement of the process. The auctions are held periodically, typically on a monthly basis, on a dedicated platform made available by OMIP S.A., with the quantity of GOs to be auctioned in each auction being defined by DGEG.
• REN-EEGO Registration – through EEGO website. For further information, please email firstname.lastname@example.org;
• Registering for the auctions – you can consult the OMIP website and contact OMIP by email at leiloes-GO@omip.pt;
• Further information about the auction calendar, volumes, and results can be consulted on the DGEG and OMIP websites.
Croatia - HROTE-CROPEX
From the beginning of 2019 and in accordance with the Law on Renewable Energy Sources and Highly Effective Cogeneration (Official Gazette 100/15, 111/18), HROTE, as a leader of the ECO Balance Group for the incentivised electricity production, started to sell a part of the energy produced on trading platforms of CROATIAN POWER EXCHANGE Ltd. (CROPEX).
By switching to the market-based sales of electricity, the possibility of establishing a system for the sales of Guarantees of Origin was opened, precisely for the electricity produced by the incentivized eligible producers and sold on the CROPEX markets by HROTE. Guarantees of Origin for the electricity produced in the power plants concerned are being issued within the Croatian Guarantees of Origin Registry and sold to the market participants on the market-based principles, i.e. through Guarantees of Origin Auctions.
According to the agreement between HROTE and CROPEX, Guarantees of Origin are sold on Guarantees of Origin Auctions that are organised by CROPEX, using specially developed IT auction trading platform. After the Auction is successfully completed, raised funds from the Auction are transferred to the incentivised system fund, while sold Guarantees of Origin are transferred from HROTE’s account in the Guarantees of Origin Registry to the Auction participant’s user accounts.

Slovakia - OKTE
In Slovakia, the Electricity Market Operator OKTE administers the GO system for electricity from renewable energy sources and electricity produced by highly efficient cogeneration.
Since November 2020 OKTE also auctions GOs for electricity for which the producer has exercised the right to support under § 3 para. 1 letter c) or letter e) of the Act on RES and VÚKVET.

Hungary - Pan-European, HUPX
On 20 September 2022, HUPX organized the first guarantees of origin auction in Europe, where all market participants active in any AIB member had the opportunity to sell GOs.

In addition, HUPX offers self-clearing, physical delivery (GO transfer / export) and settlement services in order to ensure reliable trading processes.
The main characteristics of its organized market:
- 5 order attributes: Preference handling via technology, production month, commission date, country and support type
- Available technologies: Biogas, Biomass, Geothermal, Hydro, Landfill gas, Solar, Waste, Wind and any other EECS compliant technology
- Available countries: Any AIB country
- Seller side: Hungarian and other European power plants and GO traders besides MAVIR (Hungarian TSO), who sells GOs related to the Hungarian FiT (Feed-in-Tariff) production

HUPX launched Hungary's first organized guarantees of origin market on June 14, 2022. The primer role of the new organized and transparent marketplace is to complement the already existing bilateral transactions in Hungary and to provide proper price signals regarding guarantees of origins, which will support the development of the Hungarian power market and the integration of renewables.
Overview of recent results is available on the website of HUPX.
