Romania's New Home Battery Subsidy: 400 Million Lei Program, Launch Expected in October 2026

On September 14, 2026, Romania's Ministry of Environment, Waters and Forests (MMAP) and the Environmental Fund Administration (AFM) published Order No. 1,904/2026 in the Official Gazette (Monitorul Oficial), issue no. 775, officially approving the "Financing Guide for the Installation of Energy Storage Systems for Electricity Produced from Renewable Sources."

According to a statement from the Ministry, the final version follows an extensive public consultation process, during which MMAP and AFM received and reviewed more than 200 submissions from individuals, professional associations, companies, installers, and specialists.

The program has a budget of 400 million lei (roughly $88 million) and targets individuals who already hold prosumer status. It is Romania's first national-level subsidy program dedicated specifically to residential battery storage, following the earlier "Casa Verde" rooftop solar program.

AFM funding can cover up to 75% of a project's eligible cost, capped at 15,000 lei (about €2,860), VAT included. Regardless of system size, that cap is the ceiling - no household will receive more than 15,000 lei from the state.

The maximum eligible cost standard has also been revised upward, from 1,250 lei/kWh in the draft to 1,500 lei/kWh (VAT included) in the final guide. Any cost above that per-kWh benchmark must be covered by the applicant. This increase likely reflects recent rises in equipment and installation costs.
 

One easily overlooked but important technical condition: the guide explicitly states that only batteries charged from a household's own surplus solar output - not from the grid - are eligible for funding. This condition is designed to ensure public money finances renewable energy storage rather than grid-arbitrage schemes. In practice, the storage system must be configured to prioritize charging from solar surplus and cannot be used simply as a peak-shaving device charged from the grid.

The program is open to individuals who already hold prosumer status - meaning they have a grid-connected solar system and are already generating electricity. A few eligibility details stand out:

Off-grid households do not qualify. The applicant's solar installation must be connected to the distribution grid, and the applicant must formally hold prosumer status.
 

Minimum capacity lowered. Under the final guide, the storage system must have a minimum capacity of 10 kWh, down from 12 kWh in the draft version.
 

Previously self-funded batteries no longer disqualify applicants automatically. Owning a battery installed at one's own expense is no longer, by itself, a disqualifying factor. However, the storage system purchased through the program must be new, and the same expenses cannot be funded twice from public sources.
 

No stacking of public subsidies. Applicants must not have received other public funding for the same expenses. The battery must serve exclusively the consumption and generation site where the applicant holds prosumer status, and electricity from that site cannot be used for commercial or professional activity. If a commercial activity is carried out at the same address, its consumption must be metered separately from household use.
 

One application per session. Within a single application window, each person may apply only once and only for one storage system.
 

No outstanding tax debts. Applicants must have no unpaid obligations to the state or local budget, both at their place of residence and at the project's implementation site, if different.
 

Worth noting: both households that have solar panels without a battery, and households that already have a battery and want to add or replace capacity, are eligible to apply - but funding applies only to the newly added storage capacity, not existing equipment.
 

Diana Buzoianu, Romania's interim Minister of Environment, stated that the new program will no longer operate on a "first-come, first-served" basis; applications will instead be evaluated and ranked by score. According to details released by MMAP and AFM, the scoring system totals 100 points, split between two main criteria: the applicant's own co-financing share and the requested storage capacity, each worth up to 50 points.

Capacity scoring reaches its maximum at 20 kWh - systems larger than that receive no additional points (though funding remains capped at 15,000 lei regardless). A scoring criterion tied to installed solar capacity, which was part of the earlier draft, has been removed. In effect, households offering a higher co-financing share and requesting capacity closer to 20 kWh will rank higher in the evaluation.
 

The guide sets a relatively high bar for the equipment itself:

A higher minimum battery cycle life requirement than in the draft version;

Mandatory Battery Management System (BMS) for monitoring voltage, temperature, and current;

Restricted to newer, lead-free battery chemistries such as Li-Ion, LiFePO4, and Na-Ion;

The system must be compatible with the household's existing solar inverter and support automatic charging from solar surplus (and, as noted above, cannot charge from the grid).

Since the exact figures and specifications are governed by the full text of the guide published in the Official Gazette, applicants should ask their installer for written confirmation that a given product meets these technical standards before purchase, to avoid rejection over non-compliant equipment.

It's worth emphasizing: as of late September 2026, AFM has not yet published an exact application opening date. October remains the government's stated expectation, not a confirmed date - applicants should wait for AFM's official announcement.

While the rules are now in effect, the application window has not yet opened. Applicants can start preparing the following in advance:

Prosumer contract, in the applicant's own name;

Grid connection certificate, corresponding to the same consumption site;

Electricity bill from the past three months, in the applicant's own name;

Proof of identity;

Tax clearance certificates (no outstanding debts) from both national and local tax authorities, covering the place of residence and, if different, the implementation site;

If the implementation address differs from the residence, a tax status certificate from the relevant local municipality.

One practical detail worth flagging: documents issued electronically generally must be uploaded in their original electronic format - scans or photos of electronic documents are typically not accepted. Applicants should confirm formatting requirements before submission.
 

The policy intent is straightforward: ensure public funding supports genuine renewable energy storage rather than grid arbitrage, while increasing households' self-consumption rate and easing the structural mismatch between midday solar oversupply and evening peak demand. Officials have also signaled a desire to extend the program over three to four years, meaning that even households that miss the first application round will likely have future opportunities.

For households that already hold prosumer status and are considering adding storage, the most practical steps right now are: confirm the planned system meets the 10 kWh minimum capacity and battery technology requirements, assemble the documents listed above in advance, and monitor AFM's official website (afm.ro) and the Ministry of Environment's official channels for the application launch announcement - to avoid losing scoring priority due to incomplete paperwork once the window opens.
