HEP ODS, Croatia's national distribution system operator, has confirmed that the regulatory framework for battery storage is ready for investment, with operational guidelines nearing completion. Three connection models exist: standalone systems requiring a full connection procedure, integration with existing generation facilities like PV plants, and systems for active customers.

However, rules for congestion management and system services are under development, limiting market potential. By 2030, €30 billion is needed for electricity grid investments in the Balkan region, with Croatia positioned to integrate battery storage into its well-connected power system.
