ACER has approved changes in the methodologies (The Harmonised Maximum and Minimum Clearing Price (HMMCP) methodology for Single Day-Ahead Coupling (SDAC) and The Harmonised Maximum and Minimum Clearing Price (HMMCP) methodology for Single Intraday Coupling (SIDC)) for automatically increasing the maximum price limit in case of price spikes. The timely adjustment of those price limits is needed to ensure security of supply this winter through optimal short-term dispatch of generation, efficient use of interconnections and to encourage demand response. The amended methodologies will lead to a more gradual increase of the day ahead and intraday market price limits than with the previous rules.
The methodology amendments update the conditions that will lead to fewer and smaller adjustments of the price limits. This will allow market participants to get used to the new price limits, allowing new generation and demand response to enter. Additionally, the automatic adjustment mechanism is introduced for intraday markets, triggering price limits adjustments on the intraday auctions, currently planned to be launched in the first months of 2024.
