Croatia’s EU-level tripartite framework points to 500 MW / 1,000 MWh of additional storage by 2028, while a 2026 European research snapshot estimated the country had about 66 MW of operating storage power. The figures show the gap between the target and installed capacity, while uncertainty over project terms poses a further barrier to bankability.
Growing renewable output, access to the coupled EU market and periods of high prices in Southeast Europe provide a market rationale for storage. Croatia, however, has not matched the battery commissioning pace seen 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, how grid connections are treated, access to system services and revenue certainty. Support envelopes alone do not make projects bankable, although a grant can reduce capital expenditure.
Projects also need a clear operating licence, a dispatch route, defined grid charges and predictable treatment of charging and discharging. If the 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. Such rules could help turn the country’s coupled-market position into an advantage and convert storage ambitions into operating assets.
