Vienna-based renewable energy group Enery has started construction of a hybrid solar and battery facility in Slovenia at the Jezerce project near Divača. The installation combines 7.68 MW of photovoltaic capacity with 12 MWh of electricity storage.
Project location and land use
The investment is being developed by Enery SLO, with commercial operation scheduled for May 2027. The site is located within the Gabrk motorway interchange and covers approximately 8.4 hectares of land already affected by major transport infrastructure.
The project’s siting approach prioritises previously developed or infrastructure-adjacent land to limit the use of undeveloped greenfield locations. Jezerce is also structured to provide a direct benefit to the local community.
Municipal power purchase terms
Under the project’s commercial arrangements, Divača municipality will be entitled to purchase 10% of the electricity generated at a fixed price of €88/MWh throughout the plant’s operating life. The agreement creates a long-term local electricity supply arrangement, while the wider electricity sales structure has not been disclosed.
Although Jezerce is built on one site, it will operate as six electrically separate units due to technical requirements tied to its grid connection. The configuration reflects how network connection conditions influence renewable project engineering.
Permitting timeline and grid-driven design
Grid requirements can affect electrical design, control systems, metering arrangements and integration costs for generation and storage into distribution or transmission networks. The project was initially presented in early 2023, followed by Enery obtaining its final construction permit in November 2025.
After the permit was granted, further technical adjustments were completed before construction began. Enery Group develops and operates renewable generation and battery storage across Central and Eastern Europe, reporting about 566 MW in operation across ten markets and another 213 MW under construction.
For Slovenia, Jezerce adds solar generation and storage while establishing a long-term electricity purchasing arrangement with a municipality. For Enery, the project is another example of combining generation, storage and tailored offtake arrangements within one development.
The investment’s eventual performance will depend on meeting its planned commissioning date and demonstrating that contracted municipal sales together with wider market revenues support the project’s financial assumptions.
