If the power to be contracted is lower than the installation's maximum admissible power, the customer must request an increase in contracted power from their supplier.

In situations where the power to be contracted is higher than the installation's maximum admissible power, the customer must request a power increase through the Digital Counter on our website.

See the documents required to request a power increase here.

After submitting the request for power increase, the Customer receives a communication with the initial charges (Connection Services), as defined in the Commercial Relations Regulations.

When the Customer pays the initial charges, E-REDES analyses the connection conditions of the installation and, within 15 working days, excluding pending issues, sends an estimate communication to the Customer.

This budget notification contains the network co-participation value, in €/kVA, in accordance with the Commercial Relations Regulation, corresponding to the difference between the required requested power value and the current requested power of the installation. The budget communication may also foresee the need for the construction of connection elements whenever the mains supplying the installation does not support the new desired power value.

In addition to the power increase process with E-REDES, the customer must ensure that the installation is certified for the new power value. If it is necessary to certify the installation(s), the customer must use an electrical installation inspector recognized by the General Directorate of Energy and Geology (DGEG).
