Croatia opened applications on Tuesday for a €38 million household clean-energy programme that includes battery storage support for the first time, as authorities seek to shift more rooftop solar output into increasingly stressed evening demand periods.
The scheme covers rooftop photovoltaic systems, heat pumps and battery energy storage.
Standard households can receive grants covering up to 50% of eligible costs, while support can rise to 70% for households considered at risk of energy poverty.
Maximum grants are €17,850 for standard applicants and €24,990 for eligible energy-poor households.
The inclusion of batteries is significant because Croatia’s electricity-demand profile is changing as distributed solar capacity expands.
The country recorded a new summer electricity-demand peak of about 3,400.5 MWh at 21:00 in August, after most photovoltaic production had disappeared.
That peak was higher than both the previous summer record and the latest winter maximum.
Solar installations can reduce household and system demand during the day, but they provide little support during the evening peak unless production is stored.
Behind-the-meter batteries allow households to retain part of their daytime solar output and use it after sunset.
At sufficient scale, that could reduce demand seen by the grid during the 20:00-22:00 period, when regional electricity prices are frequently highest.
The policy therefore moves beyond the first stage of rooftop solar support.
Subsidising photovoltaic installations alone can accelerate daytime generation while increasing the difference between solar-hour and evening demand.
Combining solar with storage creates a more controllable consumption profile.
The scheme may also prepare households for electricity tariffs that place greater value on when electricity is consumed.
Time-of-use or dynamic pricing can significantly improve battery economics by allowing users to avoid high-cost hours.
For the grid, distributed storage can reduce peak demand and potentially delay some network reinforcement.
The benefits depend on how batteries are operated.
Systems optimised only for household self-consumption may provide less grid value than those capable of responding to wider market signals.
Croatia is also developing larger utility-scale BESS projects, including storage alongside renewable generation.
The household programme adds a distributed layer to that transition.
The €38 million scheme is not large enough by itself to reshape the Croatian electricity system.
But it marks an important policy change.
As solar deployment increases, government support is beginning to shift from simply subsidising generation toward helping consumers move renewable electricity into the hours when the system needs it most.
