ADEX Group launched a shared intraday continuous trading environment on October 20 for Slovenia, Hungary and Serbia. The platform links the three national power markets more closely. It is another step towards integrating electricity trading in Central and Southeastern Europe.
The intraday markets operated within ADEX now use a common M7 trading environment. The arrangement standardises several technical and operational processes, but participants can trade only in the individual markets to which they have been admitted. It does not create a single regional price.
Under the new structure, 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 role expands its responsibilities within ADEX and draws on its experience operating organised electricity markets.
Common operations across three exchanges
The common environment went live after testing and migration involving BSP, Hungary’s HUPX, Serbia’s SEEPEX, market participants and project partners. The change is intended to simplify daily operations and harmonise trade-limit management. It also provides a more consistent trading framework across the three exchanges.
ADEX said the integration should make market operations more efficient and give participants a unified technical interface for intraday activity. For traders, its significance lies chiefly in the potential for faster, more consistent intraday trading. That becomes more important as renewable generation increases and balancing requirements grow more demanding.
The platform also strengthens institutional links among markets that often have substantial price differences because of transmission bottlenecks and differing generation balances. The next test is whether closer operational integration leads to deeper liquidity and more efficient short-term balancing between Slovenia, Hungary and Serbia. Physical interconnection constraints may still limit full price convergence.
