SolaX Power and Croatian energy company AVIK Energy Tech have signed an agreement to develop an initial 100 MWh of battery energy storage system (BESS) capacity in Croatia. The partnership covers battery storage projects, equipment supply and local implementation, with the first installations scheduled to enter operation between late 2026 and early 2027. AVIK Energy Tech operates as an installer, developer and engineering, procurement and construction (EPC) contractor in Croatia.
Under the agreement, SolaX Power will supply its ORI Utility All-in-One energy storage systems for the planned projects. AVIK Energy Tech will be responsible for local project development, engineering, construction and implementation. The companies will work together on battery storage installations as part of the initial 100 MWh development programme.
The first identified project is located in Novska, Croatia. It comprises a combined 10 MWh photovoltaic (PV) and battery energy storage project, with commissioning scheduled for the fourth quarter of 2026. The project forms part of the initial portfolio being developed under the agreement between the two companies.
A second project is planned in Petrinja, Croatia, where AVIK Energy Tech and SolaX Power will develop a 40 MWh standalone BESS facility. Unlike the Novska installation, the Petrinja project is identified as a standalone battery storage development. The facility is expected to enter operation during the first quarter of 2027.
Together, the Novska and Petrinja projects account for 50 MWh of the announced 100 MWh development programme. The companies have not provided locations, individual capacities or commissioning schedules for the remaining 50 MWh in the announcement.
The agreement also extends beyond the initial projects in Croatia. AVIK Energy Tech will take responsibility for development, sales, installation and maintenance operations across the wider Adria region, covering markets from Slovenia to Albania. The company will also operate as a spare parts hub for SolaX Power's ORI BESS battery storage product portfolio.
This regional arrangement expands AVIK Energy Tech's responsibilities beyond individual project construction and includes ongoing operational and product support activities. SolaX Power will provide the storage technology, while AVIK Energy Tech will manage the identified local development and implementation activities.
The partnership comes as Croatia and other Southeast European electricity markets seek additional grid flexibility to accommodate increasing renewable electricity generation. Battery energy storage systems can support the balancing of electricity supply and demand and participation in electricity markets. The planned projects in Novska and Petrinja represent the first identified developments under the companies' broader Croatian battery storage agreement.
