XBID

XBID, or Cross-border Intraday Coupling, is the project that was launched in 2012 to create solutions for intraday continuous trading across Europe and to increase overall trading efficiency within a single intraday EU electricity market.

This project was created as a joint initiative of several European power exchanges and transmission system operators (TSOs) from 11 European countries and, despite its challenging implementation, is constantly evolving. The countries currently involved or aspiring to participate in the project include Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Hungary, Germany, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden and the United Kingdom.

The project responds to the needs of the market by creating a more transparent and efficient continuous business environment that will allow market participants to easily trade their intraday positions across EU markets and without need for an explicit allocation of transmission capacity. Key questions and answers regarding the XBID project are available in the following document:


The solution is based on a common central IT system linking orders from local trading systems operated by nominated electricity market operators (NEMOs) as well as available transmission capacities between bidding zones provided by TSOs. Under a central solution, orders placed by market participants in one country may be matched with orders placed by market participants in any other involved country if there is an available cross-border transmission capacity between the concerned zones. The XBID solution supports both implicit and potentially explicit (at the request of national regulatory authorities) continuous trading and is fully in line with the EU target for an integrated intraday electricity market that is set by Commission Regulation 2015/1222 of 24 July 2015 establishing a guideline on capacity allocation and congestion management (the CACM Regulation). A Public Description of Continuous Trading Matching Algorithm is available here:


In 2017, the technical part of the XBID project was completed. It was followed by preparations of the project launch and the launch of the first wave of so-called Local Implementation Projects (LIPs). On 12th June 2018 first wave of LIPs was successfully launched and the first results were obtained one day later. Success was achieved specifically in the following countries: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Lithuania, Latvia, Norway, the Netherlands, Portugal, Spain and Sweden. This marks a major milestone in the project and follows several years of complex and intensive development and testing. Additional information can be found in the following press release.


Each LIP consists of one or more borders or interconnectors, one or more TSOs and one or more NEMOs. The main purpose of the LIP is to assign responsibilities to each party, to adapt local mechanisms such as operational procedures, custom systems and contractual framework, and to ensure readiness to participate in XBID testing.

The following figure shows the layout of LIPs as of August 29, 2017.

In May 2017, ČEPS, a.s. as the Czech TSO and OTE, a.s. as the Czech NEMO together with similar entities in Austria, Germany, Hungary, Romania and Croatia (namely 50Hertz, APG, EPEX SPOT, EXAA, HUPX, MAVIR, Nord Pool, OPCOM, TenneT and Transelectrica) set up the LIP 15 and on 17 August 2017 signed a Memorandum of Understanding on its establishment. Croatian (HOPS and CROPEX) and Slovenian (ELES and BSP) parties joined the LIP 15 in the following months. All parties to the project expressed their interest in the implementation of continuous cross-border trading and the introduction of implicit allocation of intraday cross-border transmission capacity on the Czech-German, Czech-Austrian, Austro-Hungarian, Hungarian-Romanian, Hungarian- Croatian and Croatian-Slovenian border.

The borders of LIP 15 are shown in the following figure.

All parties are also committed to actively contribute to the achievement of the European internal electricity market in line with Commission Regulation (EU) 2015/1222 of 24 July 2015 establishing a guideline on capacity allocation and congestion management (the CACM Regulation).

The parties of LIP 15 plan to start the operations after the first wave of LIPs has been successfully launched. According to the initial schedule of the XBID project, which may be subject to additional modifications, the second wave of operational implementation is expected in the first half of 2019. Market participants will be informed in advance of potential impacts on trading in the Czech Republic.
