Guarantees of Origin - New Auction Format - Opening the Sales side to the Market
OKTE, a.s. announces to market participants the upcoming change to the auctions of guarantees of origin for energy, which brings an expansion of the offer. National guarantees issued pursuant to Act No. 309/2009 Coll. for supported production sources will no longer be the only ones traded, energy producers and suppliers will also be able to enter the auction with guarantees of origin. OKTE, a.s. will act as an intermediary within the trading mechanism.
Opening the sales side to the market in accordance with the planned amendment to the Operating Rules of OKTE, a.s. effective from 1.5.2026 required a change to the auction algorithm. It will now evaluate the marginal price based on successfully matched orders in individual product categories. These will be divided by the type of source and the remaining lifetime of the guarantees of origin at the time of the auction.
The new auction format also includes a change to the financial side. Those interested in purchasing guarantees of origin will have to deposit a deposit for the given auction in advance to a specific account and the system will allow them to place orders for the purchase of guarantees of origin only up to its amount (after adding VAT). Acceptance of deposits will end 2 working days before the day of the auction itself.
All auction participants must have an Agreement concluded with OKTE, a.s. on activities related to the issuance and use of guarantees of origin.
More details about the new auctions of guarantees of origin can be found in the section GO/Auctions/General Information.
