Smart & big blocks are unique to our auctions because of their complexity and unparalleled size – allowing you to sophisticate your optimization strategy.

Big blocks: larger than classic blocks with the maximum size going up to 1500 MW and allows to cover large production capacities

Loop blocks: families of two blocks which are executed or rejected together. They allow to bundle buy and sell blocks to reflect storage activities - only offered at EPEX

Curtailable blocks: set of blocks which can be either entirely executed or entirely rejected (All-or-None); or executed above a minimum acceptance ratio defined by traders

Linked blocks:  set of blocks with a linked execution constraint, meaning the execution of one block depends on the execution of its father block. They allow to represent the variation of electricity generation with regards to the market price

Exclusive blocks: group of blocks within which a maximum of one block can be executed, so your electricity is traded at the most profitable moment

For more and more end consumers, it’s increasingly important to know where their electricity comes from, and if possible, to make a choice to switch to renewable energy completely.

However, since one cannot distinguish the source of an electron once it is injected into the network, European legislation came up with a green label called Guarantees of Origin (GOs) to enable the tracking of the origin of renewable electricity.

GOs have their challenges

The GOs tracking system brings major benefits, the most important one being that GOs allow consumers to be certain that the energy they use stems from renewable energy sources.

However, this system also has some limitations.

Indeed, until now most GOs have been traded on the OTC market, leading to a lack of transparency due to no obligation to make such GOs prices public. As a consequence, market participants are not able to know the true value of their green assets.

Today’s demand for renewables is also multi-faceted, with some wanting very specific country, region or production technology for the renewable source, while other are happy with more generic criteria of origins. This diversity of needs may be sometimes difficult to satisfy. For example, demand for cheap GOs mainly matches the numerous offers from old renewable plants, and this doesn’t allow for fully supporting new investments needed to reach the EU target of 32% renewable energy consumption by 2030.

Using our expertise to offer a solution and serve our trading community

To meet the market’s demand for more trading standards, increased transparency and robust price signals, on 28 September 2022, we successfully launched the first monthly GOs spot auction. This new market facilitates safe and seamless GOs trading across Europe, while satisfying the variety of needs for specific or generic GOs.

Our innovative market design optimally pools a wide range of generic and specific needs of market participants – fostering market liquidity to enshrine the use of GOs and support the acceleration of the energy transition.

This GOs spot auction matches today's market needs and is fit for tomorrow's evolutions.

GOs spot auction design

The monthly EPEX SPOT GOs auction is three-dimensional. That means that the product specifications take into account the following features:

1. Generation technology (wind / solar / hydro)
2. Country (country 1 / country 2 …)
3. Subsidy scheme (subsidy / no subsidy)

Market participants can either submit bids for generic products, meaning any type of technology, country of origin or subsidy scheme; or bid for specific GOs combining the different product characteristics. After the bids are submitted, specific and non-specific bids can be matched and the corresponding transactions are processed.

GOs spot auction process

The GOs spot auctions are held once a month and operated by EPEX SPOT under the exchange’s membership and market rules. Clearing and settlement is conducted by our group clearing house, ECC, and the GOs delivery is ensured through our French GO registry (held by EEX).

An organized market for French capacity guarantees.

The French law foresees a capacity obligation scheme. It specifies that electricity producers and demand-response operators receive capacity certificates by the French Transmission System Operator RTE. Suppliers have to contribute to security of supply by holding sufficient capacity certificates to cover the peak consumption of their costumers for each underlying year.

On the capacity market operated by EPEX SPOT, the demand for capacity guarantees meets the offer, determining a price for capacity which reflects security of supply needs to cover peak consumption in France.

The results of the past auctions are listed here.

The current Auction Calendar is available here.

If you wish to trade on the French capacity market, please get in touch with your Key Account manager or send an e-mail to sales@epexspot.com. You can find more information on the capacity market in our dedicated brochure and in the download section.

Detailed product specifications are available in the member section.
