XBID – 1st anniversary and announcement of 2nd Wave Go-Live

XBID, the Single Intraday Coupling (SIDC) solution, is one year old today! Since the successful go-live on June 12th/13th, 2018 over 16 million trades have been executed. Expansion of the SIDC into 7 further countries is expected in Quarter 4, 2019.

The SIDC parties are pleased to recognise a successful first year of operation with high and growing numbers of trades together with stable and robust performance. Over 16 million trades have been successfully completed since go-live in June 2018.

Preparation and testing are now well underway for a 2nd wave go-live which is expected to be launched towards the end of Quarter 4 2019. The following countries are actively involved in this expansion: Bulgaria, Croatia, Czech Republic, Hungary, Poland, Romania and Slovenia, together with the bordering countries who are already operational from the first go-live. These are Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, the Netherlands, Norway, Portugal, Spain and Sweden.

A 2nd Wave Pre-Launch Event is being planned for early October 2019 to brief stakeholders ahead of the Go-Live. A Trial Period with Market Parties is also being arranged to provide opportunities for new users to gain familiarity with the SIDC solution and undertake their own tests in preparation.

The Co-Chairs of the SIDC Steering Committee, Jean Verseille, and Stefano Alaimo, stated: “We are very pleased to have reached this important milestone of one year of operations. The growth in trading demonstrates the important role of an integrated intraday market. We look forwards to the further expansion and development of SIDC. With seven countries due to go-live by the end of 2019 this would bring the geographic coverage of SIDC to an 21 countries. There are also discussions underway about a 3rd wave Go-Live.”

SIDC is also being developed to deliver additional benefits and later in 2019 a second release of SIDC is due to be deployed. Importantly, for Market Parties, this will increase the order book depth to 100, a significant increase from the current depth of 31.
