Switch energy supplier

A simple and quick process.

Liberalized market

More information for your switch


What is? How much does it cost?

The liberalized energy market allows consumers to choose their electricity and/or natural gas supplier, choosing the solution that best fits their needs.
In the liberalized energy market, energy prices are determined by the supplier and not by ERSE.

This process has no associated cost and can be done at any time. Only the tariff will be changed, according to the supplier of your choice.


Until when do I have to change?

The transitional period of switching to the retail market runs until the end of 2020.
During this period, while staying on the regulated market, it will be able to maintain its current supplier, with a transitory tariff set by ERSE and subject to quarterly review.


Regulated price conditions

According to Ordinance no.348/2017, from January 1, 2018, traders can practice tariffs similar to the regulated tariff.

If you want to have access to these conditions and they are not made available by your supplier, you can request the termination of the contract and contract this tariff with the Supplier of Last Resort.

Your future supplier, after confirm all the information, will formalize the request for switch in the GPMC portal (Management of the Process of Switching Supplier). This may take up to 60 days.


During the switching process it will be necessary to finish the contractual relationship with your current supplier.
To do this, it is necessary to give your consumption information in your smart meter, evaluate and validate the amount to be invoiced in this transition phase. The energy distributor has a key role in this process, as it is his responsibility to give information about your smart meter.
