FAQ

Frequently asked questions.

How is the price I receive calculated?

Remuneration is indexed to the surplus imbalance market price published by REN — mercado.ren.pt. We apply no spread and no discount: what REN pays is what you receive.

UPACs are exempt from scheduling — what does that mean?

For UPACs, Portuguese regulation does not require prior production scheduling. There is no penalty for deviations between what you produced and what was forecast — unlike larger plants, which are subject to day-ahead and intraday markets.

How does invoicing work?

The period is quarterly, with a €20 minimum per invoice — otherwise it carries over to the following quarter.

How long does onboarding take?

Typically 2 to 6 weeks, depending on the state of the registrations with REN. We handle all the paperwork.

Why is Gesto different from other energy retailers?

Most retailers buy your surplus at a fixed price set below the average market potential, keeping the margin. Gesto does not buy your energy — it represents it in the market, with pass-through remuneration and a transparent service fee. Those who invest should benefit from market opportunities.
