Croatia has created its first meaningful battery-investment pipeline with 47 projects totalling more than 100 MW and about 250 MWh. Authorities have signed support contracts worth about €16.3 million, while most of the programme funding remains unused. Some batteries have already been completed, with remaining projects expected to enter operation during 2026.
The projects together represent roughly 250 MWh of storage capacity. Croatia had made around €50 million available under the programme, leaving only about one-third of the support envelope committed. Weak utilisation of available subsidies suggests storage adoption is moving more slowly than policymakers expected.
Support levels and battery revenue conditions
Battery economics depend on more than construction grants, according to the reported conditions for developers. Developers need confidence that projects can generate revenue from wholesale arbitrage, balancing, ancillary services or behind-the-meter savings. Those markets are still developing in Croatia.
Croatia’s substantial hydropower capacity provides part of the flexibility that batteries deliver elsewhere. This can reduce some short-duration storage revenue opportunities. At the same time, rapidly growing solar capacity is beginning to create stronger intraday price differences.
Photovoltaic production pushes prices lower during the day, while evening electricity remains more valuable. The resulting spreads are expected to improve the battery business case over time. Grid access is also identified as a constraint for battery deployment.
Battery developers need clear connection rules and enough network capacity to charge and discharge without creating additional congestion. Large industrial consumers may face different economics from other users. For factories, commercial facilities and logistics operators, batteries can reduce peak grid purchases and increase consumption of on-site solar rather than relying entirely on wholesale-market revenues.
A first operating benchmark for Croatia’s storage market
The 250 MWh pipeline is described as modest compared with gigawatt-hour storage developments emerging in Romania and Greece. It is positioned as a first operating benchmark for Croatia’s battery performance across local balancing and electricity markets. Developers, lenders and regulators will be able to assess how the projects perform in those settings.
If the projects produce attractive returns, remaining public funding could support a larger second wave. If they struggle, the unused subsidy budget may indicate that market design needs adjustment rather than additional grants alone. Croatia has moved storage beyond pilot projects as the next question becomes whether electricity-market revenues are sufficient for investment without substantial state support.
