Exploring HSE’s Slovenia solar battery Projects
Slovenia’s state-owned energy company, Holding Slovenske Elektrarne (HSE), has taken a major step towards expanding its renewable energy portfolio. The company signed contracts to build solar power plants with a combined capacity of 80 MW, each equipped with 20 MWh of battery storage.
Slovenian state energy company, HSE, is building 80 MW solar power plants with battery storage across three locations.
The deal was signed with a consortium led by Czech company ČEZ ESCO and its Slovenian subsidiary ENERGO ESCO. The project includes the construction of solar power plants at three different locations: Hodoš, Zlatoličje, and Formin. The total investment is estimated at 100 million euros.
These solar power plants are expected to be operational by the end of 2025, contributing significantly to Slovenia’s national goal. Slovenia aims to add 1 GW of solar power capacity by 2027. This initiative aligns with the country’s broader objective of achieving climate neutrality by 2050. This project is part of a larger trend of Slovenia solar power expansion.
HSE’s Commitment to Slovenia solar battery and Renewable Energy
HSE has been actively working towards diversifying its energy production by incorporating more renewable sources. Building on its strong foundation in hydropower, the company is now focusing on solar and wind energy projects. HSE Group stands as Slovenia’s largest producer of electricity from renewable sources. The company has already completed the first phase of its Brežice solar power plant, which has a capacity of 3 MW.
Additionally, HSE plans to build a 50 MW solar power plant at its Sava River hydropower plant. This plant will also be equipped with a 10 MWh battery storage system.
The company’s strategy includes expanding its renewable energy portfolio to 1.5 GW of solar power, 100 MW of wind power, and 300 MW of battery storage by 2030. HSE’s CEO, Viktor Vračar, emphasized the importance of these projects in the company’s long-term vision.
“By 2030, we plan to have 1.5 GW of solar power, 100 MW of wind power, and 300 MW of battery storage. These projects are essential for our strategy,” Vračar said. HSE’s investments align with broader efforts in Renewable Energy Slovenia, showcasing the nation’s commitment to sustainable energy solutions.
Collaborative Efforts for a Green Future with Slovenia solar battery
The consortium led by ČEZ ESCO and ENERGO ESCO will be responsible for the construction of the solar power plants. ČEZ ESCO is a Czech company specializing in energy services and solutions, while ENERGO ESCO is its subsidiary in Slovenia.
The involvement of these companies ensures that the projects will be completed using the latest technologies and best practices in the renewable energy sector.
Bojan Lukić, CEO of ENERGO ESCO, expressed his satisfaction with the collaboration. “We are pleased to be part of this important project for Slovenia. It is a great example of how international cooperation can lead to significant progress in renewable energy,” Lukić said.
The projects are also expected to create jobs and stimulate economic growth in the regions where the solar power plants will be built. The construction phase alone is projected to generate hundreds of jobs, while the operation and maintenance of the plants will provide long-term employment opportunities.
Slovenia’s Renewable Energy Goals with Solar Battery
Slovenia has set ambitious targets for increasing its renewable energy capacity. The country aims to add 1 GW of solar power by 2027, as part of its commitment to the European Union’s climate and energy goals. Slovenia’s solar energy sector has seen impressive 85 MW Growth in 2025, demonstrating significant progress in renewable energy adoption.
The European Commission has approved Slovenia’s plans to allocate 90 million euros in state aid for the development of solar power projects. This funding is expected to accelerate the deployment of solar energy across the country.
The solar power plants being developed by HSE will play a crucial role in helping Slovenia achieve its renewable energy targets. Once operational, these plants will significantly increase the country’s solar power capacity, reducing its reliance on fossil fuels and lowering greenhouse gas emissions.
The integration of battery storage systems in these projects is also a key component of Slovenia’s energy strategy. Battery storage will help stabilize the grid, ensuring a reliable supply of electricity even when solar power generation fluctuates due to weather conditions.
HSE’s solar power projects mark a significant milestone in Slovenia’s transition to a greener and more sustainable energy future. The company’s collaboration with ČEZ ESCO and ENERGO ESCO demonstrates the potential of international partnerships in advancing renewable energy initiatives. Furthermore, Slovenia is exploring innovative approaches such as installing solar panels on railway land to maximize its renewable energy potential.
