Subsidies
support for the construction of new renewable electricity generation facilities and battery systems
Allocation: EUR 30 million
Amount of aid: max. EUR 2.5 million / projects
Aid intensity: max. 45 %
Deadline for submission: 15 July 2025
Completion of project implementation: by 30 June 2026 at the latest
Sustainability of results: min. until 31 December 2031
Supported activities (RES + battery combination is REQUIRED):
- The project must include both parts:
- New equipment for electricity production from RES
- New battery system (for electricity storage), connected upstream of the RES transfer point
Conditions for approval of the application:
- Reserved capacity in the distribution/transmission system
- Relevant permitting documents – e.g. building permit, notification of notification, certificate of non-subjection to permitting procedure
- Completed procurement / tendering
- A contract with the supplier or a purchase order must be in place at the time of application (after evaluation of tenders)
- Work can only start after the call for tenders – the contract must not be in force before
Technical eligibility conditions:
Renewable energy installations:
Capacity: 0.5 MW – 5 MW (inclusive)
Can only be one installation or system at one connection point
One project = one type of technology (e.g. PV only, not a combination of PV and biogas)
Must be connected to the distribution or transmission system in the Slovak Republic
Battery system:
Min. capacity: 0.05 MW (50 kW)
Min. capacity: 0.1 MWh (100 kWh)
Capacity ≥ capacity
Battery capacity must not exceed the capacity of the RES device
Battery must be able to take at least 75% of the energy from the RES device
Connection upstream of the transfer point and on the manufacturer’s side
PROCEDURE FOR SUCCESSFUL APPLICATION TO THE CALL ( OZE + BATTERY)
(Prepared by SMINN)
- Procedure
STEP 1: Eligibility Verification.
- Are you a micro, small or medium-sized enterprise or do you operate under a trade license?
- Are you planning to build a new photovoltaic power source together with a battery system?
STEP 2: Preparation of project documentation.
Have an expert prepare project documentation that includes:
- design of technical solution for photovoltaic electricity source
-
compliance with technical conditions:
- Photovoltaic capacity: 0.5 to 5 MW
- battery power: min. 50 kW
- Battery capacity: min. 100 kWh
- the battery must be connected directly to the PV plant before the grid connection point
- at least 75% of the energy in the battery must come from the PV system itself
STEP 3: Obtaining the necessary permits.
- Building permit or other relevant document (notification, statement of the authority...)
- Reserving capacity on the distribution or transmission system
STEP 4: Procurement.
- you must have a signed contract with the supplier, or at least a completed public procurement with the result
👉 As a first step, you will need a technical specification. If you don't have one, contact SMINN - we can help you prepare one.
STEP 5: Preparation of the application and mandatory annexes
Complete and upload via ISPO:
- Application form
- Summary of application
-
Attachments:
- Additional data
- Proof of reserved capacity
- Authorisation to implement the project
- Contract with supplier or evaluation of the public procurement
- Budget
- Energy audit (if applicable)
- Affidavit of non-duplicative financing
STEP 6: Submitting the application
- Electronically via the ISPO system
- Deadline: by 15. 07. 2025
- The project must be completed by 30 June 2026 at the latest
- Scoring criteria - What to look for?
1. Cost-effectiveness of the project - the most important criterion
- MH SR assesses how much money you are asking for in terms of how much energy the project will produce and store.
- The lower the price per MWh, the more points.
2. Local resource - bonus points
If your photovoltaic system will be connected as a local source (according to § 4b of Act 309/2009 Coll.), you will get extra points. (max 10 points)
3. Power over 2 MW - additional bonus
If the output of your PV plant is 2 MW or more, you will receive an additional bonus. (max 5 points)
