Croatia opened applications on Tuesday for a €38 million household clean-energy programme that includes battery storage support for the first time. Authorities said the measure is intended to shift more rooftop solar output into evening demand periods that are increasingly stressed. The scheme covers rooftop photovoltaic systems, heat pumps and battery energy storage.
Under the programme, standard households can receive grants covering up to 50% of eligible costs. Support can rise to 70% for households considered at risk of energy poverty. Maximum grants are set at €17,850 for standard applicants and €24,990 for eligible energy-poor households.
Battery storage targeted at evening demand and price periods
The inclusion of batteries reflects changes in Croatia’s electricity-demand profile as distributed solar capacity expands. In August, the country recorded a new summer electricity-demand peak of about 3,400.5 MWh at 21:00, after most photovoltaic production had disappeared. The level was higher than both the previous summer record and the latest winter maximum.
Solar installations can reduce household and system demand during daylight hours, but they provide little support during the evening peak unless generation is stored. Behind-the-meter batteries can retain part of daytime solar output for use after sunset. At sufficient scale, that arrangement could reduce grid demand during the 20:00-22:00 period, when regional electricity prices are frequently highest.
Moving beyond rooftop solar subsidies
The programme extends beyond an initial stage focused on subsidising rooftop solar installations alone. Subsidising photovoltaics without storage can increase the gap between solar-hour generation and evening demand. By combining solar with storage, the policy aims to create a more controllable consumption profile.
The scheme may also help households adapt to electricity tariffs that place greater value on when power is consumed. Time-of-use or dynamic pricing can 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.
Distributed benefits depend on battery operation; utility-scale projects continue
The benefits depend on how batteries are operated in practice. 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.
This household programme adds a distributed layer to that broader transition. The €38 million package is not large enough by itself to reshape Croatia’s electricity system, but it represents a policy shift in support priorities. As solar deployment increases, government backing is moving from subsidising generation toward helping consumers move renewable electricity into the hours when the system needs it most.
