Seven further countries to be coupled with European Single Intraday Coupling

(Update, 28th Nov. 2019 below) European Single Intraday Coupling (SIDC) Solution and Local Implementation Projects confirm 2nd wave go-live date for Novem-ber 2019. Seven further countries to be coupled with the fourteen already operational.

Update 28th Nov. 2019: Pan-European trading now in place across 21 countries coupled through SIDC. System performing well. Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) confirm the successful go-live of the second launch of SIDC (formerly known as XBID). 

In the first two hours after cross-border trading opened on 19th November, OTE, the Czech NEMO, reported that more than 1 000 trades were completed for delivery on 20th November. 
The Croatian NEMO, CROPEX, recorded trades with market participants in 16 different countries including Norway and Spain. 
HUPX, the Hungarian NEMO, reported an increase in traded volumes of nearly 14 times in the five days following go-live, compared to the five prior to the launch. 
In Bulgaria, IBEX states that the average number of trades has doubled since the go-live and OPCOM, the Romanian NEMO, also reports a near doubling of both traded volumes and number of trades. 
In Slovenia, BSP Southpool has stated that for the period after go-live, compared to the equivalent period in 2018, it has seen an eight-fold increase in traded volume (11 672 MWh compared to 1 425 MWh). 
Meanwhile in Poland, TGE has achieved a daily average of over 2 000 MWh since go-live, which is a more than nine-fold increase when compared to the 2018 intraday daily average of 212 MWh.

Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) confirm the target date for the launch of SIDC (formerly known as XBID) and the go-Live of 2 further Local Implementation Projects on 19th November with first deliveries on 20th November. 

This confirmation follows the successful completion of testing and the first Market Trial peri-od. The November 2019 go-live date is still subject to completion of the required go-live prep-aration and launch activities. 

Expand the continuous trading
Marking another important step towards expanding the single integrated European Intraday market, the target go-live with the 2 additional Local Implementation Projects will expand the continuous trading of electricity across the following countries: Bulgaria, Croatia, Czech, Hun-gary, Poland, Romania and Slovenia. They join the existing countries already operating the SIDC: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Nor-way, The Netherlands, Portugal, Spain and Sweden. A 3rd wave go-live is expected by the end of 2020.

At the go-live all borders in the coupled 7 countries will be active apart from the Swedish/Polish border, which will be temporarily set to ‘inactive’ status, whilst outstanding issues are resolved. Multiple NEMO arrangements are implemented in Poland. Nevertheless, Nordpool EMCO, for the initial period from the 2nd Go-Live, will be the single shipper in Poland.

Matching bidding zones
The SIDC solution is based on a common IT system with one Shared Order Book (SOB), a Ca-pacity Management Module (CMM) and a Shipping Module (SM). 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. The intraday solution supports both explicit allo-cation on the Croatian/Slovenian and French/German borders (as requested by the respective NRAs) and implicit continuous trading. It is in line with the EU Target model for an integrated intraday market. 

Connecting intraday markets
European-wide intraday coupling 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. The purpose of the SIDC initiative is to increase the overall efficiency of intraday trading.
