Generate your own energy

The energy that benefits you

Self-consumption is the consumption by one or more electricity consumers from production facilities close to the consumption location.

If you are already a self-consumer and are connected to the grid, you can sell your energy surplus and save even more on your electricity bill. We take care of all the paperwork so that you can do it in a simple and agile way.

If you are not a self-consumer and you want to join the change to renewable energy, CEP will provide you with a comprehensive service so that you can start generating your own energy.

Professional Guide to Self-consumption Processing


Sell the electricity you do not consume

The current legislation of the Electricity Sector (Law 24/2013, of December 26) defines self-consumption and distinguishes several modalities of it.

Among these modalities, there are those facilities that, in addition to generating electricity for their own electricity consumption, can inject surplus energy into the transmission and distribution networks. This variant is called self-consumption supply with surplus.


Example of surplus compensation

Installations with surplus may be:

With surpluses with compensation

The energy that is not instantly self-consumed is fed into the grid so that at the end of the billing period the value of this surplus energy will be compensated in your electricity bill.

With surpluses not eligible for compensation

The energy that is not instantly self-consumed is fed into the grid and sold, obtaining the electricity market price for it.

With either of the two modalities, self-consumption installations offer you significant savings on your electricity bill.

If you are a self-consumer and wish to sell your surplus, we take care of all the necessary procedures so that you can make the most of your installation.
