The growing demand for electricity storage is making investments in this sector increasingly profitable. And it will be conducted entirely online. In 2025, entrepreneurs and investors can apply for co-financing for the construction of electricity storage facilities. What are the program's conditions and what should be paid attention to when submitting an application? Here is the most important information!

When can applications be submitted?

The National Fund for Environmental Protection and Water Management (NFOŚiGW) announced that the application submission process will begin on April 4, 2025, and will last until May 30, 2025. However, it is worth not delaying and preparing the documentation in advance, as the order of submissions may affect the allocation of funds.

What can co-financing be obtained for?

The program includes financial support for three key areas:

  • Construction of electricity storage facilities (at least 2 MW capacity and 4 MWh capacity), including technical infrastructure and testing (mandatory element).
  • Construction of grid connection and accompanying infrastructure (optional element).
  • Configuration and adaptation of the storage facility, including management and remote monitoring systems (optional element).

What are the financial requirements?

If the investment is carried out in a "Project Finance" model, the investor must provide at least 15% of their own funds (excluding loans, bonds, and borrowings). Before submitting the application, it is necessary to present documents confirming possession of these funds.

How are applications evaluated?

The following criteria are subject to evaluation:

  • Analysis of the investor's financial situation – the company must not be in poor financial condition.
  • Projected financial stability – the investor must demonstrate the ability to ensure the project's sustainability.
  • Financial structure – sources of financing for both eligible costs and VAT, as well as other expenses, must be documented.
  • Cost-effectiveness of the project – scoring depends on the level of expenditure per MW, MWh, and Mg CO2.
  • Investment readiness for implementation – additional points for possessing key administrative approvals and infrastructure.

What documents need to be submitted?

To successfully apply for co-financing, the applicant must submit a number of documents, including:

  • Decision on environmental conditions for the project or a ruling on the lack of necessity to issue such a decision.
  • Decision authorizing the investment.
  • Conditions for connecting the storage facility to the power grid (issued by 30.05.2025).
  • Documents confirming the right to dispose of the real estate on which the investment undertaking will be carried out, and a map showing the location of the task.
  • Documents confirming the legal status of the applicant (e.g., statute, company agreement).
  • Schedule for obtaining necessary decisions and permits.
  • Project implementation schedule.
  • Methodology for calculating the ecological effect.
  • Powers of attorney/authorizations to sign the co-financing agreement.
  • Agreement between the applicant and the entity bearing eligible expenditures.
  • Feasibility Study and Financial Model.
  • Financial statements for the last three years.
  • Statistical reports and auditor's reports.
  • Copies of documents confirming the balance of project financing sources.
  • Simplified technological diagram and a list of documents confirming compliance with the DNSH principle throughout the project lifecycle.

How to increase the chances of obtaining co-financing?

To increase your chances, it is worth:

  • Preparing complete technical and financial documentation. (the application must be correctly signed)
  • Obtaining the required administrative approvals (e.g., building permit, environmental decisions).
  • Documenting full readiness for investment implementation.
  • Submitting the application as soon as possible, as in case of equal scores, the submission date is decisive.


The co-financing program for the construction of energy storage facilities in 2025 is an excellent opportunity for investors interested in modern energy technologies. Proper preparation and meeting all criteria increase the chances of obtaining financial support.

We implement energy storage investments from A to Z. We will gladly prepare the necessary documentation and co-financing application, deliver components, build and connect energy storage facilities, and install our proprietary energy management system.

FAQ

Frequently asked questions

About energy cost optimisation in companies — answered in 30 seconds.

Three biggest levers: consumption profile (when you use power), fixed fees (contracted power, capacity charge), and market instruments (day-ahead market, DSR, energy storage). The fastest wins come from analysis — without it, it's hard to pick where to start.

EMS (Energy Management System) is a decision layer that controls energy in real time — when to buy, when to use storage, when to clip peaks. It pays off where energy is a meaningful operating cost and consumption profile varies.

Typically 4–7 years. The exact payback depends on contracted power, consumption profile, tariff and whether you can join DSR / system services. For 200 kW+ sites with high variability, ROI under 5 years is common.

It's a system fee billed during 4 peak hours on business days. You can really lower it by shifting consumption out of those hours — an EMS does this automatically; manually it's only partial. Often the fastest-growing line on your invoice.

Yes, but not for every company. Self-consumption is what matters — whether you use energy when the panels produce it. PV alone, without storage or profile shifting, often doesn't pay back fast. With storage + EMS the model changes fundamentally.

ETS pushes up energy prices via the CO₂ cost embedded in wholesale prices. ETS2 (from 2027) will hit transport and heating fuels. Companies that don't actively manage energy are more exposed — these aren't isolated price hikes, they're a trend.

First response within 24 business hours. The full analysis with potential calculations (peak shaving, storage, DSR, tariff optimisation) usually takes 3–7 business days, depending on data completeness from the DSO.
