The price of 1 kWh of electricity seems to be simple information. In practice, the answer depends on whether we ask only about active energy or about the actual cost visible on the bill. The selected tariff, seller, network operator, place of residence and the times in which we use energy are also important.
In 2026, there is another element: an increasing selection of multi-zone tariffs and offers with dynamic prices. Energy can cost the same around the clock, less at night, or change the price with the market situation.
So how much does 1 kWh of electricity really cost? We check the current rates, compare the G11, G12 and G13 tariffs and explain when a dynamic tariff can reduce your bills.
From 1 January 2026, the average price of electricity sales in tariffs approved by the President of the Energy Regulatory Office for households is PLN 495.16/MWh net. This is about PLN 0.495 per 1 kWh before adding excise duty and VAT. After taking them into account, the energy itself costs about PLN 0.615/kWh gross (this is an average price, as it depends on consumption, the method of conversion to kWh and even the location of the house).
However, this is not an amount that can be multiplied by the number of kilowatt hours from the meter.
Therefore, the real cost of taking 1 kWh from the grid is higher than the price of active energy alone. There is no single correct rate for the whole of Polish – distribution tariffs vary between operators, and part of the fixed costs depends on the annual energy consumption.
The ERO indicates that the sales tariffs for 2026 are lower than the “frozen” price applied in 2025. At the same time, distribution rates together with system fees increased by about 7.6% on average. For a typical household in the G11 tariff, consuming about 1.8 MWh per year, the regulator estimated the increase in the entire bill at about 3%.
The table below shows examples of official rates in force in 2026. They should not be treated as one nationwide price – they are primarily intended to show the scale of differences between individual billing models.
| Tariff | How does it work? | Example gross energy price in 2026 | For whom? |
| G11 | One price around the clock | approx. 0.62 PLN/kWh | Houses with relatively even consumption during the day |
| G12 | Two price zones | e.g. 0.7170 PLN/kWh day and 0.4205 PLN/kWh night | People who can shift some of their consumption to cheaper hours |
| G13 | Three time zones | price depends on the zone and seller | Homes with high and flexible consumption, heat pump or EV |
| Dynamic fare | The price depends on the energy market | No single rate – changes over time | People who actively manage consumption or use automation and energy storage |
For example, in Enea’s tariff for 2026, energy in G11 costs 0.6187 PLN/kWh gross, while in G12 it costs 0.7170 PLN/kWh in the day zone and 0.4205 PLN/kWh in the night zone. In PGE, prices are 0.6189 PLN/kWh in G11 and 0.7018 and 0.4635 PLN/kWh in G12, respectively.
These are the prices of energy sales. Distribution and other fees must be added to the final bill.
The amount of some fees is set centrally. In 2026, the RES fee rate is PLN 7.30/MWh, and the cogeneration fee is PLN 3/MWh.
The capacity fee for households, on the other hand, depends on the annual consumption of:
| Annual energy consumption | Capacity fee in 2026 |
| less than 500 kWh | 4.29 PLN/month |
| 500–1200 kWh | 10.31 PLN/month |
| above 1200 to 2800 kWh | 17.18 PLN/month |
| over 2800 kWh | 24.05 PLN/month |
That is why two households using the same amount of energy can have different bills.

The choice of tariff is becoming more and more important. In the past, many households simply used G11 and did not analyze the hours of consumption. Today, a washing machine, dishwasher, heat pump, air conditioning, electric car or energy storage make it much easier to transfer consumption to other times of the day.
G11 – one price around the clock
G11 remains the most popular tariff for households. According to the Energy Regulatory Office, it is used by nearly 90% of consumers covered by household tariffs.
Its biggest advantage is simplicity.
It doesn’t matter if the washing machine runs at 11:00, 17:00 or 2:00 at night – the price of energy resulting from the sales tariff is the same.
The G11 will be a good solution primarily when:
However, simplicity comes at a price. You can’t use cheaper periods in the same way as in the G12, G13 or dynamic tariff.
G12 – more expensive in one zone, cheaper in another
G12 divides the day into two zones. Their hours depend on the operator.
In one of them, the price is higher, in the other it is clearly lower. The difference is well illustrated by Enea’s tariffs for 2026: 0.7170 PLN/kWh gross in the day zone compared to 0.4205 PLN/kWh in the night zone.
Such a tariff can be beneficial for people who use a significant part of their energy outside peak hours.
This includes, for example:
However, just changing from G11 to G12 does not guarantee savings. If most of the consumption is still in the more expensive zone, the effect may be the opposite.
G13 – three zones instead of two
The G13 allows you to adjust the cost of energy even more precisely to the time of consumption. The day is divided into three zones, and their hours may additionally change depending on the season.
For example, in TAURON, the G13 tariff distinguishes between summer and winter. The most expensive evening hours fall in summer from 19:00 to 22:00, and in winter from 16:00 to 21:00. In other hours and on holidays, you can use more advantageous zones.
This solution is particularly interesting for households with high energy consumption.
A heat pump, electric car or energy storage can work on schedule and avoid the most expensive times.
However, it should be remembered that G13 is not a uniform offer available on identical terms throughout Poland. Group names, zones and prices depend on the operator and seller.
Here the principle is completely different.
In G11, G12 or G13, the hours and rates are determined in advance. In a dynamic price contract, the cost of energy is linked to the current quotations of the energy market.
Such offers from the largest retailers are available to households from August 24, 2024. The condition for using them is a remote reading meter that allows you to record consumption in appropriate time intervals.
The price can therefore be very low during times of high energy supply, but increase significantly during the evening peak.
ERO points out that the price in a dynamic contract is usually built on the basis of TGE’s day-ahead market quotes, increased by costs or the seller’s margin. However, the specific formula depends on the agreement.
For example, Pstryk currently provides a formula based on TGE’s hourly dynamic price increased by PLN 0.08/kWh net service fee. This is an example of a specific seller’s offer, not a general rule for all dynamic tariffs.
There is no point in entering current dynamic prices in an article as a single table – they may lose their validity the next day. Next-day market prices can be checked on an ongoing basis in the data of the Polish Power Exchange, while the final price for the customer should always be verified with the selected seller. Check information about the energy market on TGE

There is no tariff that will be the cheapest for everyone.
The key is the consumption profile, i.e. information about not only how much energy we consume, but also when we do it.
| How to use energy | A tariff worth analyzing |
| Consumption evenly distributed around the clock | G11 |
| High consumption at night | G12 |
| Heat pump, EV and the ability to control operating hours | G12 or G13 |
| Large, flexible consumption and smart meter | Dynamic fare |
| Photovoltaics and energy storage with EMS | dynamic or multi-zone tariff |
| No possibility to shift consumption | G11 |
Before changing the tariff, it is best to download the hourly data from the meter and analyze several weeks or months.
It may turn out that the problem is not the amount of the rate itself, but the moment when the house consumes the most energy.
That is why, with multi-zone and dynamic tariffs, photovoltaics, energy storage and intelligent consumption management are becoming increasingly important.
Photovoltaics – produce energy for your own needs
A photovoltaic installation allows you to cover part of the current demand with energy produced on the roof.
A washing machine, air conditioner, heat pump or car charger can then use PV production directly. Such energy does not have to be purchased from the seller beforehand.
From the perspective of the household budget, self-consumption is therefore particularly important – the greater the part of our own production we use immediately, the less energy we need to take from the grid.
In the case of prosumers, this is of additional importance due to net-billing. Surpluses that go into the grid are settled according to market rules, so one’s own energy consumption is often more valuable than its immediate return.
Energy storage – save cheap energy for later
Photovoltaics produce the most energy in the middle of the day. A house, on the other hand, often needs it in the morning and evening.
Energy storage allows you to shift this energy over time.
The diagram might look like this:
Photovoltaics → current consumption → energy storage → grid
In the evening:
Energy storage → home appliances → grid
On a farm using a dynamic tariff, the storage can have another function. Depending on the device and the way it is configured, it can be charged from the grid when energy is cheap, and then power the house during high price hours.
However, this does not mean that every storage facility will automatically perform such price arbitrage. What you need is the right configuration, a compatible inverter and an energy management system.
EMS – don’t check prices every hour
Analysing energy prices every day and manually turning on devices would quickly become inconvenient.
The EMS or HEMS system can do some of this work automatically.
Depending on the devices used, it may include:
This allows energy to be collected, stored and used when it is more cost-effective.
Not everyone needs a warehouse right away.
The first step can cost exactly PLN 0.
If you are using G12, G13 or dynamic pricing, check if you can change the operating hours of energy-consuming appliances: dishwasher, washing machine, dryer, boiler, heat pump, air conditioning, EV charger.
With a single device, the difference may seem small. On the scale of several thousand kilowatt hours per year, it starts to matter.
Let’s assume that a household draws 4000 kWh of energy from the grid per year.
If most of the consumption is for more expensive hours, changing the tariff itself will not help much. However, if part of the operation of the heat pump, car charging or household appliances can be postponed to a period of lower prices, the average purchase cost of each kilowatt hour may decrease.
Even more control is given by the combination of:
photovoltaics + energy storage + dynamic tariff + EMS.
In such a system, the house does not have to react only to the price of electricity. It can also use its own production and store energy for hours when buying from the grid is less profitable.
However, you should not assume a specific percentage of savings without analyzing data from a given building. The result depends on consumption, installation, energy prices, storage capacity and the possibility of shifting consumption.
How much does 1 kWh of electricity cost in Poland in 2026?
The average price of energy sales for households approved by the President of the Energy Regulatory Office in 2026 is PLN 495.16/MWh net, i.e. approximately PLN 0.495/kWh net. After adding excise duty and VAT, this corresponds to approximately PLN 0.615/kWh gross for energy alone (converted for kWh consumed). However, distribution costs and fixed fees are added to the final bill.
Is 0.62 PLN/kWh the full price of electricity?
No. This is a value similar to the price of active energy alone in regulated tariffs. The bill also includes distribution, system fees and a fixed part. Therefore, the actual cost per 1 kWh is higher.
Which is cheaper – G11 or G12?
It depends on the hours of consumption. The G11 offers one price around the clock. In the G12, electricity is cheaper at certain times and more expensive at others. If a large part of the consumption can be transferred to a cheaper zone, the G12 may be more advantageous.
Who can the G13 tariff be profitable for?
Primarily for households with high consumption and the ability to control the equipment. It can be interesting for a heat pump, electric car, electric heating or energy storage. The availability and rules of the G13 depend on the operator and the retailer.
What is a dynamic tariff?
It is an agreement in which the price of energy changes depending on the market situation. It is most often linked to the quotations of the Polish Power Exchange. It may allow you to use very cheap hours, but it also means the risk of a high price during peak periods, so it is worth combining it with automatic energy management.
Can the price of energy be negative in a dynamic tariff?
There are periods with negative energy prices on the wholesale market. However, this does not automatically mean that every retail customer will receive an identical price below zero. The method of taking into account negative prices depends on the formula of a particular seller. The ERO indicates that suppliers may apply their own mark-ups, limits or the method of taking into account exchange prices.
Where can you check electricity prices for tomorrow?
Day-ahead market prices are published by the Polish Power Exchange. A customer using a dynamic tariff should additionally check prices in their seller’s application or website, as other components may be added to the exchange price.
Check the data of the Polish Power Exchange
Is photovoltaics still profitable at prices of around 0.62 PLN/kWh?
When assessing profitability, one should not look only at the price of active energy. In-house production reduces the amount of energy taken from the grid and thus part of the consumption-dependent costs. However, the result depends on the size of the installation, self-consumption, net-billing and how surpluses are managed.
Does energy storage help with dynamic tariff?
It can help especially if the system allows you to charge the storage facility during lower prices and use the stored energy later. The greatest possibilities are provided by combining the storage with the EMS system, which automatically controls the flow of energy.
How do I know which tariff will be best for my home?
It is best to analyze the consumption data in individual hours. Only then can you compare how the same profile would behave in G11, G12, G13 or at a dynamic price. Current offers of sellers can be additionally checked in the CENKI comparator maintained by the Energy Regulatory Office.
Check how much you can pay for energy
Your electricity bill no longer depends solely on the number of kilowatt-hours you use. It is increasingly important when you consume energy, how much you produce yourself and whether you can store it for later.
Photovoltaics, energy storage and smart management allow you to approach these costs as a single system.

The information presents the situation as of 25 August 2026. Tariffs, free market offers and dynamic prices are subject to change. Before making
The Council of Ministers adopted draft law UC84, prepared by the Ministry of Energii.
This is one of the most important reforms of the rules for connecting installations to the power grid in recent years-and a real signal that the energy transition is entering a new stage.
What does this mean in practice?
This is a change that rewards well-designed, viable projects, rather than ‘ reserving capacity for the future.’
Energy ceases to be a ‘black box’ – it becomes a service that can be planned and consciously managed.
The law introduces:
This is the foundation for a stable, modern and blackout-resistant powersystem.
Because UC84 is not a cosmetic correction, but a real ‘unblocking’ of the market-for investors, performers and recipients of energii.
This is a step from procedural chaos to a responsible systemic energytransition.
In the coming months, it is the quality of design, integration of renewable energy with energy storage, and conscious capacity management that will determine the competitive advantage.

Solutions using renewable energy sources are popularized by financial support programs, which makes it possible to reduce investment costs. Owners of single-family residential buildings who want to install a heat pump or photovoltaics in their home, also have the option of deducting it from the tax as part of the thermomodernization relief.
Are you wondering if the heat pump can be tax-deductible? Such a possibility was provided for in the thermo-modernization relief. It allows for the deduction of costs related to the implementation of thermo-modernization projects from the tax base. The aim of its introduction was to encourage homeowners to undertake thermo-modernization projects, i.e. activities to insulate residential buildings and choose ecological heat sources.
According to Art. 2 point 2 of the Act on supporting thermo-modernization and renovation of November 21, 2008. The thermo-modernization project is considered to be:
Expenses for the purchase of building materials, devices and services related to the implementation of the thermomodernization project can be deducted from the tax.
Not everyone has the opportunity to take advantage of the thermo-modernization relief. The most important rule is the taxpayer’s settlement according to the tax scale, flat tax or registered lump sum.
It is also necessary to be the owner or co-owner of a single-family residential building no later than on the day of deduction. Therefore, the tenant, owners of multi-family buildings and people who are just building a house will not be able to use the settlement.
Expenditure on building materials, equipment and services related to the implementation of a thermo-modernization project may be deducted from income tax. It is important, however, that the total amount of the deduction does not exceed PLN 53,000. PLN. This amount is granted per one taxpayer, which means that if he is the owner or co-owner of several buildings, he is entitled to a limit of PLN 53,000. PLN for all projects carried out in them.
The tax deduction is made for the project completed within 3 consecutive years, counting from the end of the tax year in which the first expense was incurred. The deduction is made on the basis of the value from VAT invoices in the settlement for the tax year in which the expense was incurred. Invoices do not need to be attached to the settlement, however, they should be kept for at least 5 years, in the event of a fiscal control.
In the event that the amount of the deduction is higher than the taxpayer’s annual income, the legislator provided for the possibility of deducting in the next 6 years from the end of the tax year in which the first expense was incurred.
For more information on the settlement, see: How to account for photovoltaics in PIT? Thermomodernization relief for photovoltaic installation
Thermomodernization relief is a solution that allows you to deduct from income tax expenses incurred for the purchase and installation of a heat pump. This significantly reduces the investment costs in this type of heating system, and thus increases its profitability.
It is also worth noting that in the case of using financial assistance from programs such as clean air, only the part of the costs that was financed from own funds can be deducted from the tax. The amount obtained under the grant is not deductible.
