DGEG solar registration in Portugal for expats

DGEG is the Portuguese energy regulator. Every grid tied solar installation must be registered before it can legally export to the grid, and the paperwork is entirely in Portuguese.

DGEG solar registration in Portugal is a legal requirement for every grid tied residential solar installation. DGEG (Direção-Geral de Energia e Geologia) is the Portuguese energy regulator, and all systems that connect to the EDP grid must be registered through its SERUP portal before they can legally export electricity. The process is entirely in Portuguese, takes 30–90 days, and involves both DGEG and your local grid operator (usually EDP Distribuição). Many installers leave some or all of the registration to the homeowner. This is the detail that most often catches expats by surprise.

The registration process, step by step

1

Technical design approval

Your installer submits a technical project (projeto técnico) to EDP Distribuição before installation begins. Without this approval, the installation cannot proceed legally.

2

Installation and inspection

After installation, EDP Distribuição inspects the connection point and approves the grid tied connection. Some installers coordinate this; others leave it to the homeowner.

3

DGEG registration (SERUP portal)

The homeowner or installer registers the system on the SERUP portal, the DGEG's official system for registering small-scale renewable energy producers (UPAC). The portal and all documentation are in Portuguese.

4

Certificate of exploitation

DGEG issues a certificate (certificado de exploração) that must be held on file. The system is not legally operating until this is issued. Timeline from submission: typically 30–90 days.

What catches expats off guard

Most Portuguese homeowners navigate DGEG registration with some difficulty; expats face the same bureaucracy in a second language. The most common surprises:

  • The SERUP portal requires a Portuguese NIF (tax number) and the system documentation in Portuguese
  • Installers often include DGEG registration in their quote but handle only part of the process
  • The timeline is largely outside your control: DGEG can take 60+ days to issue the final certificate
  • The system is technically non-compliant until the certificate of exploitation is issued, even if it is generating power
  • EDP Distribuição and DGEG are separate organisations. Delays at one do not speed up the other

What the Blueprint covers on DGEG

The Blueprint explains the full registration process in plain English for your specific installation type, and reviews your installer's quote to confirm who is responsible for each step. If the quote is ambiguous about DGEG (which they often are) we flag it before you sign.
