European Single Intraday Coupling (SIDC) Solution and Local Implementation Projects confirm the 2nd wave go-live date for November 2019. Seven countries: Bulgaria Croatia, Czech Republic, Hungary, Poland, Romania and Slovenia will be coupled with the fourteen already operational. A 3rd wave go-live is expected by the end of 2020.
The aim of Single Intraday Coupling (SIDC) is to create a single pan European cross zonal intraday electricity market. An integrated intraday market will increase the overall efficiency of intraday trading by promoting effective competition, increasing liquidity and enable a more efficient utilisation of the generation resources across Europe.
The SIDC solution is based on a common IT system with one Shared Order Book, a Capacity Management Module and a Shipping Module. It allows for orders entered by market participants for continuous matching in one bidding zone to be matched by orders similarly submitted by market participants in any other bidding zone within the project’s reach as long as transmission capacity is available.
It is a key component for completing the European Internal Energy Market. With the rising share of intermittent generation in the European generation mix, connecting intraday markets through cross-border trading is an increasingly important tool for market parties to keep positions balanced.
