"In the regulated market of mainland Portugal, the transitional tariffs for sales to end customers in Low Voltage Normal (BTN) show, on average, a variation of 1.0% in 2026," it reads.

On October 15th, ERSE had presented its proposal for a 1% increase in the price of electricity for households in the regulated market, and the proposal was submitted to the Tariff Council for an opinion.

According to the energy sector regulator, the proposed increase now translates to a rise of between €0.18 and €0.28 in the monthly bill, including taxes and fees.

Starting in January, considering a power rating of 3.45 kilovolt-amperes (kVA) and a consumption of 1,900 kilowatt-hours (kWh) per year for a couple without children, the total to be paid will be €36.82, including taxes and fees (except for the DGEG - Directorate-General for Energy and Geology fee).

For a couple with two children, with a power rating of 6.9 kVA and a consumption of 5,000 kWh/year, the bill will be €95.03 (including taxes and fees).

At the end of September 2025, 817,000 customers were in the regulated market.

"In the liberalized market, prices for end customers vary between suppliers and depend on the commercial offer contracted by the customer," ERSE reminded.

The final price of electricity in the regulated and liberalized markets (whose prices vary between suppliers and depend on the contracted offer) includes the value of network access tariffs, regulated by ERSE.

Between December of this year and January 2026, network access tariffs will vary by -2.9% in very high voltage, -0.8% in high voltage, 1.8% in medium voltage, 2.7% in special low voltage, and 3.5% in normal low voltage.

Next year, consumers with social tariffs will have a 33.8% discount.
