1 REN - Redes Energéticas Nacionais is one of just three European companies to manage both very high-voltage electricity and high-pressure natural-gas grids. OUR MISSION To ensure the uninterrupted supply of electricity and natural gas at the lowest cost, while satisfying quality, safety and security criteria, maintaining a real time balance between supply and demand, and providing the systemic conditions for a viable energy market. PUBLIC SERVICE CONCESSIONS IN PORTUGAL Electricity transmission Natural gas transmission Reception, storage and regasification of liquefied natural gas (LNG) Underground natural gas storage Wave energy

3 Electricity REN - Redes Energéticas Nacionais transmits electricity in Portugal and ensures the technical management of the Portuguese electricity grid under a concession agreement with the Portuguese state which runs until 2057. REN operates the National Transmission Grid (RNT), which links producers to consumption centres. It balances energy demand and supply, ensuring an uninterrupted supply of electricity at the lowest cost, providing quality of service, safety and security. REN has over 17,800 electricity pylons REN has approximately 8,400 km of power transmission lines RNT delivery points enable supply to the distribution grid, which in turn feeds the majority of final consumers. Electricity companies are responsible for managing relations with final consumers, including invoicing and customer service. REN has the specialist skills and know-how to manage and integrate renewable energy sources (RES) into the national electricity grid. This is the result of Portugal s investment in this form of energy in recent years. 2013 figures show that 57% of all Portuguese consumption now comes from RES. In order to boost integration of the Portuguese and Spanish electricity grids, REN operates on the Iberian Electricity Market (MIBEL). It provides connection capacity for the daily and intra-daily markets, long-term capacity allocation via Financial Transmission Rights (FTRs), and operation and settlement for the ancillary services markets, including cross-border exchange mechanisms.

7 Natural Gas REN Gasodutos is responsible for transmitting natural gas at high pressure and for providing overall technical management of the national natural-gas grid. It receives, stores and regasifies LNG, and stores natural gas underground. These tasks are covered by concession agreements with the Portuguese state that run until 2046. The pipeline network is 1,298 km long Each ship delivers about 130,000 m 3 of liquefied natural gas to Sines, which is enough to supply Portugal for a week. REN Gasodutos operates the National Natural-Gas Transmission Grid (RNTGN), which receives natural gas at the Spanish border or at the Sines terminal and delivers it to distributors or high-pressure end customers. The LNG terminal at Sines is operated by REN Atlântico, and the underground storage of natural gas is provided by REN Armazenagem.
