Power markets deliver transparent price signals under increased supply pressure

EPEX SPOT accompanies members in tense market situation and launches products for a more sustainable power community

EPEX SPOT Annual Market Review


  • Successful launch of first pan-European spot auction for Guarantees of Origin
  • Go-live of Intraday market in Poland
  • Intraday volume reaches new yearly record
  • Establishment of new Power Exchange in Central and South-Eastern Europe - ADEX

Amsterdam / Berlin / Bern / Brussels / London / Paris / Vienna, 23 January 2023

A total of 611.21 TWh was traded on EPEX SPOT in 2022: 476.6 TWh were traded on the Day-Ahead segment and 134.6 TWh on the EPEX Intraday. The Intraday market surpassed the record of the previous year again and reached an all-time high (2021: 123.3 TWh).

Market participants were under a lot of pressure in 2022, a pivotal year marked by the energy crisis in Europe. This crisis led to higher prices and more volatility on the spot market, mainly caused by a price increase of the gas market - an important fossil fuel for power generation in peak hours - and lower than usual renewable and nuclear generation. The dry weather conditions also had an impact on conventional assets, where low river water levels hindered the transportation of lignite and caused a lack of cooling water for nuclear power plants.

Despite these fundamentals explaining price developments on the spot market, the market itself and its functioning was under severe public scrutiny, as the financial pressure on businesses and end-consumers continues to grow.

Ralph Danielski, Chief Executive Officer of EPEX SPOT, states: “It is absolutely crucial that the vulnerable end-consumers are shielded from the impact of this crisis. However, there is a difference between retail and wholesale prices and their role for the energy system. The wholesale price formation in Europe is essential and one of the most efficient systems in the world. I once again call upon policy-makers: The well-functioning mechanism of establishing the price signal secures supply at the lowest possible cost every day of the year. It also tells us that important investments are necessary to move away from costly fossil fuelled generation and that we have to invest into demand-side flexibility. We should listen to what this price signal tells us rather than throwing overboard a market design built across European countries over the last 20 years, and that creates an annual welfare of 34 billion Euros for all Europeans.” In the context of this debate, the European Power Exchange has been very vocal about how to best improve the market design based on collaboration, transparency and investment.

Projects and New Products

Speeding up the energy transition is a central endeavour in overcoming the current crisis. In 2022, EPEX SPOT launched a series of initiatives to contribute to these efforts through market-based solutions. In September 2022, the first pan-European spot auction for Guarantees of Origin (GOs) took place. GOs are today the only way to sustainably track the origin of electricity consumed, and to certify it as renewable. This pan-European auction is the first of its kind, an innovative multi-dimensional market design allows to maximise liquidity through standardised products while taking into account the specific product characteristics needed by market participants. Transactions are cleared via European Energy Clearing (ECC) and traded GOs are delivered via the French registry held by European Energy Exchange (EEX).

Furthermore, EPEX SPOT has started a cooperation with GOPACS to significantly increase the activation of flexible capacity for congestion management in the Netherlands. The efficient use of flexibility is key to tackle costly grid congestions largely caused by the intermittent feed-in of renewable production. In the same vein, the Exchange participates in the European Horizon project ENFLATE agreed to create a concrete use case of a Local Flexibility market in Switzerland. In order to further advance the efficient integration of renewables into the market, EPEX SPOT also launched weather-based power indices in cooperation with Speedwell Climate Limited, a leading provider of weather-related data. These indices allow renewable producers to better manage the risks of their assets.

In the Exchange’s ongoing efforts to enhance and expand its product and trading offer, EPEX launched Intraday trading in Poland in February 2022. This brought the highly performant M7 trading system as well as Europe’s largest community of automated trading providers to the Polish market. In addition, EPEX has continuously improved the performance and robustness of M7, ensuring a record-level system availability during the year, all in a context of steep increase of system load. Following strong demand from trading members, EPEX SPOT increased and harmonised block parameters for all coupled Day-Ahead markets, and Block and Smart Block orders were newly introduced for the GB Intraday auctions coupled with Ireland. Enhanced block parameters allow for an easier optimisation of assets by market participants. Furthermore, the Exchange has launched a new membership model to ease access for a wider and more diverse range of organisations to join.

Jonas Törnquist, Chief Operating Officer of EPEX SPOT, comments: “Especially in the context of the current energy crisis, we take our mission to provide reliable market solutions that cater to the needs of a more sustainable power community in Europe very seriously. Energy supply issues are mainly causing this crisis, and the power market is a key driver out of it. The power market enables investments into renewable capacities and demand side flexibility and focusses the efforts of all of us in the industry to continue to innovate and create a stronger energy system for the future of all Europeans”.

Operating power markets in 2022 remained a deeply European endeavour. A project of 16 Transmission System Operators and 10 Power Exchanges introduced flow-based market Coupling in the so-called Core region, optimising cross-border flows between 13 countries. It enhances the European grid’s ability to manage fluctuations in the supply of wind, solar and other renewable energy.

With the objective to foster power trading and Market Coupling in Central and South-Eastern Europe, EPEX SPOT along with Slovenian and Serbian TSOs launched ADEX, the Alpine-Adriatic Danube Power Exchange. The main milestones of ADEX will be to deliver the coupling of the pivotal Serbian Day-Ahead market with the pan-European Single Day-Ahead Coupling (SDAC) as soon as possible.
