NEMOs (Nominated Electricity Market Operators) and TSOs (Transmission System Operators) under the MCSC (Market Coupling Steering Committee) would like to ask market participants for feedback on a new order type that is aimed to be introduced on the day-ahead market (SDAC).

NEMOs and TSOs participating in the Research & Development (R&D) stream with regards to the Euphemia algorithm used for the day-ahead market have been working on designing a new type of order that would support bidding for systems that can buy and sell energy during the same day – so-called storage orders. This new order type will expand the possibilities for market participants’ bidding in the day-ahead market beyond the current order types. The storage order allows market participants to optimise the storage system bidding with less detailed market forecast and with no risk of losing money.

Currently the expected go-live of the new storage order on the SDAC market is planned for Q4/2027.

A webinar with markets participants to guide them through the questions from the public consultation is planned for June 16th, 2026, from 12:30 to 14:00 CEST.

If you have any questions regarding the public consultation, please send them to the following email address: info@mcsc-communication.eu

This public consultation will run from 01/06 until 30/06, end of day.
