Belpex SA of Belgium is a 100% subsidiary of APX.

As an experienced and innovative European energy exchange, we offer an efficient, transparent and secure electronic trading environment and provide market data for use by traders, energy suppliers and energy-intensive industries. In addition, APX promotes market innovation and creates new opportunities by working closely with its members, Transmission System Operators (TSOs) and other power exchanges.

Single Integrated Market

APX shares the vision of the EU for the realisation of a single, integrated market. APX therefore focuses on delivering an integrated electricity market through its involvement in projects such as the North-Western European Price Coupling and the establishment of an integrated European Intraday market. It will remain a leading force in the design process of market coupling and act as one of its daily operators.


The shareholders of APX are TenneT Holding BV (70.84%), owner of TenneT TSO BV, the Dutch Transmission System and Elia System Operator NV (29.16%), the Belgian electricity TSO. APX operates from offices in Amsterdam (headquarters), Brussels, and London.

TSO ownership of an energy exchange is common practice in many European countries, motivated by the need to optimise the available grid capacity with respect to market conditions, physical characteristics and constraints. More broadly, it fits with an important objective of fully independent and unbundled grid companies to promote an efficient, transparent and liquid energy market in North-Western Europe. In addition, this ownership structure guarantees a fully independent operation of the exchange.
