Who we are

Every odd-numbered year, REN presents a proposal for planned investments (Development and Investment Plan for the Electricity Transmission Grid [Plano de Desenvolvimento e Investimento da Rede de Transporte de Eletricidade] – PDIRT), which seeks to schedule future investments in the grid, currently very focused on energy transition and on the electrification of the economy.  

This PDIRT proposal is evaluated by the Portuguese Directorate-General of Energy and Geology (DGEG), and its revision is the responsibility of the Portuguese Energy Services Regulatory Entity (Entidade Reguladora dos Serviços Energéticos – ERSE). After a public consultation period, ERSE gives its opinion, from which REN draws up the final PDIRT proposal, sending it back to DGEG. The plan is then sent to the Government for decision. 

Investment in the Electricity Transmission Grid 

The investments in the Portuguese National Transmission Grid (NTG) defined in the PDIRT have taken into account the increase in energy consumption at a national level and the need to carry out the energy transition and the electrification of the economy. In recent years there has been an increase in renewable energy generation, so investments in the NTG have focused on transmitting that renewable energy to consumption centres. More recently, there has been a significant increase in interconnection capacity between Portugal and Spain as part of the development of the Iberian Electricity Market. 

By the end of the first quarter of each odd-numbered year, REN must submit a proposal for the Development and Investment Plan for the Natural Gas Grid (Plano de Desenvolvimento e Investimento da Rede de Gás Natural – PDIRGN) to the Portuguese Directorate-General of Energy and Geology (DGEG). The final version, accompanied by the opinion of the Portuguese Energy Services Regulatory Authority (ERSE) and the results of the public consultation, will be submitted to the Government for approval.
