Croatia’s EU-level tripartite framework points to 500 MW / 1,000 MWh of additional storage by 2028. A 2026 European research snapshot estimated that operating storage capacity was about 66 MW, highlighting the gap between the country’s target and its installed scale.
The market case is supported by growing renewable output, access to the coupled EU market and periods of high prices in Southeast Europe. However, Croatia 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, but investors need clarity on the conditions for earning those revenues.
Questions include network tariffs, how grid connections are treated, access to system services and revenue certainty. Support envelopes alone do not make projects bankable, although grants can reduce capital expenditure. Developers also need a clear operating licence, a dispatch route, defined grid charges and predictable treatment of charging and discharging.
If those rules remain uncertain, developers may hold permits without reaching financial close. Croatia’s next step is to establish standardised project rules that lenders and optimisers can price, including clear tariff and market-access arrangements. Predictable terms could help turn the country’s coupled-market position into an advantage and convert storage ambitions into operating assets.
