Practical Experience from Energy Multimarket Short-term Trading

At the same time, distributed energy resources began influencing local grid conditions, prompting DSOs to explore market‑based procurement of flexibility for congestion management and grid optimization. As a result, flexibility (defined as the ability to adjust an asset’s operating schedule) can now be traded across multiple markets. Aggregation platforms and virtual power plants have therefore become essential for coordinating distributed flexibility and allocating it to the most valuable markets.

This paper presents practical experience from the Senergy-Nets multimarket pilot in Ljubljana,

Slovenia, based on a district heating system. First, the paper outlines EU short‑term markets and trading opportunities for flexible assets. Second, it describes the multimarket trading setup used in the Slovenian pilot. Third, it discusses operational and regulatory challenges identified during the demonstration. The conclusions aim to support asset owners, system operators, technology providers, and policymakers in preparing for future multimarket flexibility activities.
