Amprion, RTE and EnBW TNG offer a harmonized Intraday capacity allocation platform. EPEX Spot realizes integrated Franco-German Intraday market place

The transmission system operators, Amprion and EnBW TNG in Germany and RTE in France have successfully launched an harmonized mechanism for Intraday cross-border capacity allocation on the Franco-German border starting from 13 December 2010 for first deliveries on 14 December. Consequently, as of 14 December, the European Power Exchange EPEX Spot has started offering to its members the opportunity to access an integrated Franco-German Intraday market place.


This mechanism of continuous implicit allocation on intraday, allowing in parallel explicit allocation for OTC trades, is the very first of its kind in Europe: an open, flexible and efficient mechanism of Intraday capacity allocation. It has been established in an accelerated implementation timeframe with a minimum change of existing market rules and infrastructures, aiming at fulfilling efficiently all market participants' requirements and power system security.

This new harmonized cross-border capacity allocation mechanism, implemented by the Transmission System Operators on a continuous "first come-first served" principle, is based on an existing Intraday Capacity Service (https://www.intraday-capacity.com), already used on most of the German borders (DE-CH, DE-FR, DE-NL, DE-DK1). This harmonization also enables implicit allocation of cross-border capacity to trading platforms in the Franco-German Intraday markets.

EPEX Spot has successfully activated the connection of its intraday trading system, ComXerv, to the Intraday Capacity Service. In this way, an integrated Franco-German Intraday market place is available to the EPEX Spot members without any impacts in the current trading and clearing practices. Clearing and settlement of the
traded energy will be done by the European Commodity Clearing AG (ECC), the clearing house for all EPEX Spot markets. Integration of Intraday markets is crucial for the development of liquidity, in particular with respect to the efficient use of increasing renewable energy. France and Germany represent together more than 1,150 TWh of yearly power consumption at the heart of the European market, which means about 40 % of the total power consumption in the European Union.

About Intraday Market


Concerning interconnection capacity allocation, TSOs start intraday capacity allocation after the daily auctions. Intraday capacity allocation mechanisms are different depending on the borders. Generally, the Intraday Market refers to the market which starts after the closure of the Day-ahead Market, and consequently occurs until few hours before delivery. Intraday Markets are the last opportunity for market participants to balance their positions. On EPEX Spot, the Intraday Market is a continuous market which opens at 15:00 the day before the delivery, and closes one hour before delivery.
