Value Chain

 
The electricity industry in Portugal can be divided into five major functions: generation, transmission, distribution, supply and operation of the regulated electricity market. Of these we are principally engaged only in transmission.

Electricity generators produce electricity in power plants using a variety of primarysources and technologies (coal, gas, fuel, water, wind, biomass, among others). The principal electricity generators in Portugal currently are EDP Produção, a subsidiary of EDP Tejo Energia and Turbogás.

REN Rede Eléctrica operates the transmission grid connecting generators and distributors and matching supply with demand. We are currently the only electricity transmission company in mainland Portugal.

Electricity distribution companies distribute electricity received from the national transmission and distribution grids directly to consumers. EDP - Distribuição - Energia, S.A. is currently the largest high voltage and medium voltage distribution company in Portugal.

Electricity supply companies are responsible for managing client relationships with customers, including billing and customer service. EDP Serviço Universal, which acts as a last resort supplier of the national electricity system, is currently the main supplier in Portugal. Currently, the principal supply companies in Portugal are EDP Commercial - Comercialização de Energia, S.A., Endesa, Iberdrola and Unión Fenosa.
