In a decision taken on Friday 28 March, the Agency for the Cooperation of Energy Regulators (ACER) approved the proposal by the Nominated Electricity Market Operators (NEMOs) - the market operators designated by each Member State to organise the short-term electricity markets - to modify the methodology of single intraday coupling (SIDC) products, in accordance with the European regulation on capacity allocation and congestion management (CACM).
This revision allows the introduction of products with a granularity of 15 minutes as part of the continuous intraday market and intraday auctions. It harmonises the methodology of the intraday market (SIDC) with that of the daily market (SDAC), already modified in September 2024 to introduce 15-minute products.
The aim is to increase the flexibility of short-term electricity markets and harmonise trading rules across the European internal market. And for good reason: the greater use of variable renewable energies, such as wind and solar power, means that market positions need to be adapted quickly. Intraday trading therefore appears to be a lever for the most optimal supply-demand adjustment, in near real time.
The adoption of this amendment is in line with the integration of the internal electricity market, since it would both improve the efficiency of cross-border capacity allocation and reduce barriers to entry for players operating in short-term products. NEMOs are now required to implement these changes as soon as possible.
