ADEX Group has launched a shared intraday continuous trading environment linking Slovenia, Hungary and Serbia’s electricity markets. The platform went live on October 20 following testing and migration involving the three exchanges, market participants and project partners. It brings ADEX’s intraday continuous markets into a common operational framework.
Common M7 environment and operational responsibilities
Under the new arrangement, Slovenia’s BSP has assumed operational activities for ADEX’s intraday continuous markets. BSP is now the central operational contact for participants across the three exchanges. The expanded role builds on BSP’s existing experience operating organised electricity markets.
The platform places the intraday markets in a shared M7 trading environment, standardising a range of technical and operational processes. Participants will continue to trade only in the individual markets where they are admitted. The change is intended to simplify daily operations and harmonise trade-limit management across BSP, HUPX and SEEPEX.
ADEX said the integration should make market operations more efficient and give participants a unified technical interface for intraday trading. The arrangement also establishes a more consistent trading framework across the three exchanges.
Intraday trading and physical market constraints
For traders, the significance lies less in creating a single regional price than in improving the speed and consistency of intraday trading. That is relevant as renewable generation increases and balancing requirements become more demanding. The development also strengthens institutional links among Slovenia, Hungary and Serbia.
The three markets frequently record significant price differences because of transmission bottlenecks and varying generation balances. The next test is whether closer operational integration can lead to deeper liquidity and more efficient short-term balancing between the countries. Physical interconnection constraints will continue to limit full price convergence.
