Electricity market

The energy sector is developing rapidly. The process of European market integration began some years ago. Its purpose is to create a single European market that enables market parties to trade gas and electricity across national borders easily and efficiently.

European Cross-Border Intraday (XBID) Solution and 10 Local Implementation Projects announce a revised go-live date for June 2018.

Nominated Electricity Market Operators (NEMOs[1]) and Transmission System Operators (TSOs[2]) announce a revised target date for the launch of XBID and the go-Live of 10 Local Implementation Projects of 12th June with first power deliveries on 13th June.

This revision enables additional testing to be undertaken to ensure the robustness of the  XBID. It also provides opportunities for Market Parties to take part in two Market Trial Periods which will help build XBID familiarisation. All dates remain subject to the successful completion of this testing.

Marking an important step towards creating a single integrated European Intraday market, the target go-live with the 10 Local Implementation Projects will deliver continuous trading of electricity across the following countries: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, The Netherlands, Portugal, Spain and Sweden. Most other European countries are due to take part in a second ‘wave’ go-live with XBID in Spring/early Summer 2019.

The XBID solution is based on a common IT system with one Shared Order Book (SOB), a Capacity 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 allocation (where requested by NRAs) and implicit continuous trading and is in line with the EU Target model for an integrated intraday market.  

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 XBID initiative is to increase the overall efficiency of intraday trading.    

The June 2018 go-live date is still subject to completion of System and Local Implementation Projects’ Testing, Market Parties Testing and clarifications needed from the National Regulatory Authorities (NRAs) for the Intraday Operational Agreement. The two Market Trial periods are scheduled for 26th February to 2nd March inclusive and 14th to 18th May inclusive.
