How the Polish market works

The energy regulator is URE (Urząd Regulacji Energetyki). It approves the household tariffs of the large sellers and the distribution tariffs of the regional network operators. The national grid is run by the transmission operator PSE, while your home connects to a regional distribution operator (OSD). URE's 2026 decision covers the five largest: PGE, Tauron, Enea, Energa and Stoen Operator (URE: tariffs for 2026).

As in most countries, the company that sells you electricity and the company that owns the network are different. The seller sets your energy price and your export settlement; the network operator decides how and where a battery or solar system may connect. The four default (ex officio) sellers are PGE Obrót, Tauron Sprzedaż, Enea and Energa Obrót, but you can buy from any licensed seller.

Electricity prices and the end of the price freeze

For households, the frozen energy price of 500 zł/MWh net applied until the end of 2025. From 1 January 2026, URE-approved tariffs apply again, with an average energy price of 495.16 zł/MWh, which URE reports as about 1% below the old frozen price. That figure is before VAT and excise and covers only the energy itself (URE: tariffs for 2026).

Distribution is a separate part of the bill. URE says distribution rates rose by an average of 9.36% in 2026, and by about 7.6% on average once the additional fees on household bills are included. Your final price per kWh therefore depends on your seller, your network operator and your tariff group, so use the numbers on your own bill when sizing a battery.

Distribution tariffs come in single-zone and multi-zone groups (for example G11, G12 and G13), and the cheap hours differ by operator. We did not verify the 2026 zone hours for each operator, so check your operator's tariff table before planning around a cheap overnight window.

Dynamic-price contracts

Households can sign a contract where the energy price follows the hourly day-ahead market (RDN) on the power exchange. URE's guidance says these offers suit households that understand the market, have a remote-reading meter and are billed monthly. It also warns that savings depend on shifting use away from expensive peaks, which URE gives as roughly 18:00 to 21:00, and that poor habits can raise a bill (URE: dynamic-price contracts).

Uptake is still small. According to URE's report published on 29 May 2026, 4,836 households had a dynamic-price contract at the end of 2025, with 10 sellers offering them. Households on these contracts give up the capped price that applied in 2025, and smart meters are required (URE: report on dynamic-price contracts). Average annual prices across sellers ranged widely, so compare the terms, fees and notice period, not just the headline price.

A battery is what makes a dynamic contract workable for most homes, because it can buy at the cheapest hours and use the electricity later. We explain the arithmetic in dynamic energy contracts and how to actually save and how to earn money with a home battery on a dynamic tariff. Negative prices are covered in negative electricity prices explained.

Selling surplus solar: net-billing

Poland's prosumers (households with a renewable microinstallation) settle under net-billing, which replaced the earlier net-metering system for new installations. Electricity you send to the grid is valued at the market price of energy and credited to a prosumer deposit. You then draw on that deposit when you buy electricity from the grid, so the benefit is a credit against your bills, not a cash payment at the full retail price.

Two market prices are in use. The hourly price (RCE) reflects the real value of energy in each hour. Prosumers who started producing before 1 July 2024 can keep settling at the monthly average price (RCEm), and can switch to the hourly price by sending a declaration to their seller. From 27 December 2024 the value of the deposit for a given month is increased by 23% (Ministry of Climate and Environment: changes for prosumers).

This is why a battery matters more under net-billing than under net-metering: electricity you store and use yourself in the evening displaces electricity you would otherwise buy, instead of being exported at a market price and credited later. If you are still on net-metering, check whether your existing arrangement stays more favourable before you change anything.

Grants: the PME2 programme for home batteries

The current national grant is Przydomowe Magazyny Energii, part 2 (PME2), run by the National Fund for Environmental Protection and Water Management (NFOŚiGW) from the EU Modernisation Fund. Applications opened on 20 October 2026 at 9:00 and the programme page lists the call as running until 1 October 2027, or until the PLN 1 billion budget is used up. Applications are submitted online (programme page: PME 2).

The grant for an electricity battery is 30% of eligible costs, capped at PLN 800 per kWh of nominal capacity. The per-unit cap is PLN 16,000 for prosumers on net-billing and PLN 8,000 for those on net-metering. An extra bonus of up to PLN 2,000 (not more than 50% of the battery's eligible cost) is available once for an EU-made hybrid inverter or an EU-made battery. The overall maximum, including heat storage, is PLN 19,000 per connection point.

To qualify, the home needs a grid-connected renewable microinstallation such as solar panels, and the battery must meet technical conditions: at least 10 kWh of nominal capacity, capacity in Wh of at least twice the PV peak power in Wp, a price of no more than PLN 3,000 per kWh for the battery itself, demonstrated backup (island) operation, and an energy management system (EMS) that can control charging and discharging on time profiles. The EMS must also meet the cybersecurity standards listed in the rules. Mobile storage, self-assembled batteries and uncertified systems are excluded.

Costs incurred from 1 November 2025 are eligible, so a battery already installed may still qualify. Gramwzielone.pl reported about 1,100 applications in the first two days. Because the money goes first come, first served, check the current status on the programme page before you rely on it. A previous call, PME1, was funded separately and its applications are being assessed first; we did not review its rules.

Other support is harder to pin down. The earlier Mój Prąd programme, which also funded batteries, has been reported as closed to new applications. We could not confirm whether the Czyste Powietrze programme funds home batteries, so we do not list it as a route; ask NFOŚiGW or your local contact point before assuming it does.

VAT on a home battery

We could not confirm in a primary source which VAT rate applies to a home battery supplied and installed in a house in Poland, so we do not state a rate here. Polish VAT law has a reduced 8% rate for certain construction and installation work in housing within size limits, and installers have applied it to solar installations on homes. A 2021 explainer put those limits at 300 m² of usable floor area for a house and 150 m² for a flat, but it did not say how a battery is treated and it predates the current rules.

Ask the installer to state the VAT rate and its legal basis on the quote in writing. The Ministry of Finance has also said that a prosumer who sells surplus electricity can, in principle, be treated as a VAT taxpayer, and that each case depends on the settlement model and contract (reported by Gramwzielone.pl in June 2026), so ask a tax adviser if you are unsure. Grants under PME2 are calculated on eligible costs, so confirm whether the cost base is net or gross of VAT in your own case.

Grid connection and registration

A microinstallation of up to 50 kW can be connected by notifying the network operator when the customer is already connected, according to the Ministry of Climate and Environment, which cites Article 7(8d4) of the Energy Law. Adding a battery to an existing system also changes the installation, so tell your operator before you commission it and keep the paperwork (Gramwzielone.pl: balcony PV and the ministry's answer).

A change takes effect on 1 December 2026. Gramwzielone.pl reports that an amendment to the Renewable Energy Sources Act, signed in October 2026, lets a battery be up to 2.2 times the power of the PV installation without being counted towards the microinstallation's connection power, so prosumers can add storage without new connection conditions. The total power fed into the grid by the installation and the battery together still cannot exceed the PV power (Gramwzielone.pl: larger storage without changing the connection). We could not check the text of the law itself, so confirm the details with your operator.

Separately, the EU is introducing a registration duty for home batteries. See our note on the EU rule that home batteries over 2 kWh must be registered by February 2027.

Safety, building rules and fire protection

Poland has recently written home storage into its construction rules. According to a legal summary on Gramwzielone.pl (2 October 2026), storage up to 30 kWh installed outside a building needs no notification or permit under the Building Law or fire rules, storage from 30 to 300 kWh needs a construction notification with fire-safety agreement, and a use permit is not required for storage. Murator reported the same 30 kWh threshold for building-mounted units in January 2026. These are secondary summaries, and one of them does not cover units installed inside buildings, so ask your installer which category your project falls into and how they will document it (Gramwzielone.pl: how to install a home battery legally).

Most home batteries are well under 30 kWh. Under PME2 the battery must have an EMS, work in backup mode and be a certified system, which also screens out uncertified products. For solar, the ministry says PV systems up to 6.5 kW need no fire-safety approval and no notification to the State Fire Service. We found no equivalent statement for home batteries.

Fire-safety guidance for storage is still being written. CNBOP-PIB and the Polish Energy Storage Association (PSME) plan to publish guidelines by the end of 2026, but their working title covers large-scale and industrial storage, not homes (Gramwzielone.pl: fire guidelines for energy storage). Until then, follow the manufacturer's installation instructions, use certified equipment and an installer with the right electrical qualifications, and read our guides on fire risk and chemistry and installing a battery outside.

Plug-in solar and plug-in batteries

Poland has no separate legal category for plug-in (balcony) solar. In September 2026 the Ministry of Climate and Environment said that the rules for other prosumer microinstallations generally apply to balcony systems, that it is not working on extra facilitation, and that it plans no dedicated subsidies. It said the main obstacles for flat dwellers are access rights and housing-association rules, not the energy regulations. Systems under 0.8 kW are not subject to the EU grid code NC RfG, according to the same answer.

We found no Polish rule that allows or regulates a plug-in battery connected to a normal socket, so we treat it as unregulated rather than permitted. The practical advice is to avoid it as a way of skipping your operator or installer, and to remember that PME2 excludes mobile storage. Our comparison of plug-in and installed home batteries explains the technical differences, and the balcony power plant buyers guide covers the storage option.

Outside Poland

Rules, tariffs and incentives for home batteries differ from country to country, so do not apply the figures on this page to a home elsewhere. We are adding guides for other countries to this section.
