An EU-level tripartite framework points to 500 MW / 1,000 MWh of additional storage for Croatia by 2028. A 2026 European research snapshot estimated that the country had only about 66 MW of operating storage power. The figures illustrate the gap between the 2028 ambition and Croatia’s installed scale.
Croatia has growing renewable output and access to the coupled EU market, while periods of high prices in Southeast Europe provide a market rationale for storage. The country has not matched the pace of battery commissioning in Bulgaria, Romania and Hungary. Regional scarcity lifted prices across central Southeast Europe during Week 42, when Croatia’s baseload average was about EUR 230.49/MWh.
Storage can benefit from discounts during solar hours and price premiums in the evening. Investors need clarity on network tariffs, the treatment of grid connections, access to system services and revenue certainty. Support envelopes alone do not make storage projects bankable, although a grant can reduce capital expenditure.
Projects also need a clear operating licence, a dispatch route, grid charges and predictable treatment of charging and discharging. If the rules remain uncertain, developers may hold permits without reaching financial close. These conditions affect whether projects can advance beyond permits.
Croatia’s next step is to establish standardised project rules that lenders and optimisers can price. Clear, standardised tariff and market-access rules could turn the country’s coupled-market position into an advantage and help convert storage ambitions into operating assets.
