The G12 tariff is part of the multi-zone tariff. When is it worth changing the tariff group?
Choosing the right tariff can significantly reduce energy bills, especially in times of rising electricity prices. The G12 tariff allows for real savings, but also requires implementing appropriate habits at home. This solution is especially recommended for people who use electric heating or plan to consume more energy at night.

As rachuneo.pl explains, the G12 Tariff will work well in homes where most devices – such as a washing machine, dishwasher or heating – can operate at night. That is why this solution will not necessarily be adequate to the needs of families or companies where consumption takes place mainly during the day.

However, it is worth considering shifting energy consumption to off-peak hours, because this tariff allows you to save on your bills. It is also a good option for people who are able to change their daily routines.
The G12 tariff is part of the multi-zone tariff. When is it worth changing the tariff group?
There are many energy suppliers on the market that offer the G12 tariff, including: PGE, Energa, Tauron, Enea and E.ON. Each of them offers different contract terms and hours of cheaper electricity. As rachuneo.pl explains, off-peak hours vary depending on the distributor:
- PGE, Enea, Energa, E.ON: 1:00 p.m.–3:00 p.m. and 10:00 p.m.–6:00 a.m.
- Tauron: 1:00 p.m.–4:00 p.m. and 10:00 p.m.–7:00 a.m.
The energy system is not evenly loaded 24 hours a day. The lowest demand for electricity occurs at night and on non-working days, which is why prices are lower then.

What does choosing the G12 tariff mean in practice for the electricity consumer's wallet? The price of 1 kWh in the two-zone G12 tariff in 2026 depends on the seller and the zone. The cheaper rate (night/afternoon) is usually around PLN 0.54–0.69 gross. In turn, the more expensive one (which occurs at the peak of consumption) is approximately PLN 1.03–1.33 gross.
This tariff is profitable with a minimum transfer of 40-50%. consumption per hour cheaper, e.g. using heat pumps or storage heaters.
For comparison, the average price of electricity for 1 kWh in 2026 is from PLN 96 to PLN 1.09 gross, depending on the selected distributor. However, there are fixed fees that increased in 2026.
The consumer pays the seller for the energy consumed. The amount of the bill depends on the amount of energy used, the selected tariff and any protective mechanisms. The invoice includes an active energy fee (variable) and a commercial fee (fixed), and sometimes additional fees for services or insurance.
