NODES AS and the Croatian Transmission System Operator Plc. (HOPS) are pleased to announce a new research and development partnership aimed at exploring and enhancing baseline methodologies for flexibility assets in Croatia’s balancing market. This collaboration will leverage the NODES Trading Platform to test and validate innovative approaches, supporting the evolution of Croatia’s energy landscape toward greater flexibility, transparency, and efficiency.

As the energy sector undergoes rapid decarbonization and decentralization, the need for robust and adaptive baseline methodologies has become critical for the accurate verification and settlement of flexibility services. The partnership will address key challenges such as verification accuracy, asset variability, data quality, and compliance, while also preparing for future market reforms and technological advancements.

Through this project, NODES and HOPS will:

• Share expertise and knowledge from previous initiatives across Europe.
• Conduct platform-based tests using the NODES Trading Platform, which offers advanced data collection and baseline calculation functionalities.
• Evaluate and refine baseline methodologies at both individual asset and aggregated portfolio levels.
• Support fair market access and future harmonization efforts across the EU.
