The government is providing an additional 10 million euros, and a new call for applications is expected to be published with unchanged conditions. What does this mean for businesses?
Slovenian companies have clearly demonstrated in recent weeks that battery energy storage systems are no longer a technology of the future, but one of the key investments of the present. Public call JP REPWR SUB-HEE-PO25 for non-repayable financial incentives to legal entities for the purchase and installation of electricity storage systems was May 18, 2026 closed due to the depletion of available funds. The Ministry of the Environment, Climate and Energy announced that from the Climate Fund, Borzen is allocating an additional 10 million euros for new incentives, which are expected to support approximately 200 projects.
From slow uptake to exceptional interest
Just recently, it seemed that part of the allocated funds would remain unused. Then, a turnaround occurred. Following the response from investors who announced the imminent completion of their projects, the ministry once again increased the amount of funds available under the call to 16,913,970.61 euros on May 7, 2026. Just a few days later, the funds were depleted.
The reason is not surprising. Companies are facing higher energy costs, connection capacity limitations, the need for greater self-sufficiency, and demands for more efficient consumption management. A battery storage system combined with a solar power plant allows for better control over energy flows, optimization of self-consumption of electricity, and reduction of peak loads.
What does the new public call bring?
According to information from the ministry and Borzen, a new public call is being prepared, under which new funds from the Climate Fund will be available for investments in electricity storage systems. Borzen states that the new call will be intended for legal entities, and the ministry has announced presumably unchanged conditions.
In the previous call for applications, legal entities, sole proprietors, and cooperatives engaged in economic activity were eligible for incentives. The subject was investments in the purchase and installation of new electricity storage systems, whereby the electricity storage system had to be purchased, installed, and connected to the electricity grid before the application was submitted.
The incentive amounted to up to 45% of the recognized eligible investment costs, but no more than 225 euros per 1 kWh of electricity storage capacity. Eligible costs included the purchase and installation of the storage system and a hybrid inverter, associated electrical installations and equipment, and necessary construction, craft, and installation works.
Why are companies rushing?
A key feature of the previous call was that companies could not submit an application based solely on a planned investment. The storage system had to be connected to the grid before the application was submitted. This means that companies that prepared their project on time have an advantage, selected an appropriate technical solution, arranged the documentation, and completed the connection.
Therefore, for the new call, preparedness will be crucial. Companies that start now will be significantly closer to submitting a complete application when the call opens.
With the intelligent GridIQ management system, an electricity storage system is a business tool
In practice, the value of a storage system is not measured solely in kilowatt-hours. A properly designed system allows a company to:
• increase the utilization of its own energy from a solar power plant,
• peak shaving and reduction of grid fees,
• consumption and production monitoring,
• support for charging infrastructure,
• zero grid export where required,
• greater energy independence,
• dynamic operational optimization is enabled when the system operates based on electricity market prices.
Geo Energy develops customized energy solutions for small and medium-sized enterprises and the industrial sector, focusing on optimizing electricity consumption with energy storage systems. The process includes a consumption review based on a 15-minute profile, concept preparation, project documentation, implementation, technical support as well as operation and maintenance of the system.
What should companies do before a new call is announced?
The most important first step is an energy analysis. Without understanding the 15-minute consumption profile, it is not possible to correctly determine the storage capacity, inverter power, charging and discharging strategies, and the economics of the investment.
Before making a decision, a company must answer a few key questions: when peaks occur, how much energy an existing or planned solar power plant produces, how much energy is consumed directly, where connection capacity limitations arise, and what the investment's goal is. The goal could be cost reduction/revenue generation, increased self-sufficiency, transitioning to a more favorable consumption profile, more stable power supply, or a combination of several effects.
This is precisely why the storage system must be planned as part of the company's overall energy system, not as an isolated device.
Subsidies are an opportunity, but the quality of the solution is crucial
An additional 10 million euros will open a new investment window for companies, but the subsidy alone does not guarantee a successful project. A successful investment requires proper sizing, safe technology, quality execution, and long-term system management.
Geo Energy offers energy storage systems with a strong emphasis on safety, efficiency, and reliability. The solutions enable self-consumption optimization, peak shaving, demand control, production control, arbitrage, and other advanced energy management strategies.
Companies that are prepared will have an advantage
The rapid closure of the public call is clear proof that the market is moving. Electricity storage systems are becoming a strategic investment for companies looking to reduce costs, increase energy independence, and better manage future electricity price fluctuations.
Since the new public call is expected to be published shortly, now is the right time to prepare. Companies that have a timely energy analysis, technical concept, documentation, and implementation plan prepared will be in a significantly better position when the call opens.
Geo Energy assists companies from the initial consumption analysis to the implementation of the storage system and long-term system management. If you are considering an investment in an electricity storage system, now is the time to check the technical and economic feasibility of the project.
