The electricity market in Portugal: what you need to know
In Portugal, any domestic consumer can freely choose their electricity provider in the liberalized market — and switch whenever they find a more advantageous option, at no cost and without penalties.
The market is divided into two segments: the regulated market, managed by SU Eletricidade with tariffs set by ERSE, and the liberalized market, where over 24 retailers compete with their own tariffs. In practice, the liberalized market frequently offers more competitive conditions — but comparison requires attention, because the price per kWh is not the only relevant factor.
An electricity bill in Portugal comprises several components: the energy cost (price per kWh × consumption), the contracted power (daily fixed cost, calculated in kVA), the Audiovisual Tax and taxes such as VAT and ISP. To find the cheapest electricity provider for your case, you need to calculate the total cost — not just compare the price per kWh in isolation.
The choice of time-of-use regime also impacts the bill: with a flat tariff you pay the same price all day; with a dual-rate tariff, consumption during off-peak hours (usually night and weekends) is cheaper, while peak hours are more expensive. If you have flexibility to shift consumption — washing machine, appliances or electric vehicle charging — the dual-rate tariff can generate significant savings.
The Poupa na Energia comparator analyzes your real electricity bill and calculates the total annual cost with each active retailer, taking all these factors into account. Ranking is done exclusively by cost, without any commercial influence. Tariff data is imported directly from ERSE and updated daily.

Questions about the liberalized market, tariffs and how switching electricity provider works in Portugal.
Upload the PDF of your electricity bill. Our technology automatically extracts your consumption data — contracted power, time period and kWh consumption — and compares line by line with every active tariff in Portugal, both regulated and liberalized. In seconds you see the real cost with each of the 24+ providers, the estimated annual savings and the calculation methodology. No email required, no account created, and the PDF file is deleted after analysis.
There is no single answer — the cheapest electricity provider depends on your consumption profile: how many kWh you consume per month, contracted power (kVA) and whether you consume more during the day or night (flat, dual-rate or tri-rate tariff). The comparator calculates the real total cost for your consumption, not just the price per kWh.
Yes, without any interruption. Switching electricity providers in Portugal is regulated by ERSE and is fully transparent: the distributor (E-REDES) stays the same — only the retailer changes. The process takes 15 to 21 business days, is completely free and can be done at any time without penalties. The physical distribution grid is not affected.
In most cases, yes. The regulated market (SU Eletricidade) serves as a reference. The liberalized market has tariffs significantly below that value — including fixed-price options (protected from MIBEL variations) and spot market-indexed options. The right choice depends on your risk profile and consumption. Our comparator shows both options side by side, with the total cost calculated for your case.
With a dual-rate tariff you pay different prices depending on the time of day: "off-peak hours" (usually night and weekends) are cheaper, "peak hours" are more expensive. It pays off if you have flexibility to shift consumption — washing machine, appliances, electric vehicle charging — to off-peak periods. If your consumption is concentrated during the day, the flat tariff may be more advantageous. The comparator calculates both options with your real consumption.
Yes. Poupa na Energia receives no commission, sponsorship or compensation from any electricity retailer in Portugal — including EDP, Galp, Endesa, Iberdrola, Goldenergy or Repsol.
