27 THE NATURAL GAS SECTOR IN PORTUGAL

28 NG operators NG comes from third countries. One part is received by HP pipelines and the other by sea LNG. REN Gasodutos holds the public service concession for the HP transport of NG. Overall technical management of the NNGTN, to guarantee the continuity and security of supply. Responsibility for proposing developments of the system.

29 NG operators REN Atlântico holds the concession for the reception, storage and regasification of LNG at the Sines LNG terminal REN Armazenagem holds a concession for underground NG storage in Carriço in the municipality of Pombal (center of Portugal).

30 Reception, transport, storage and regasification NG in gaseous form at HP is received from the gas pipeline at the Spanish boarder. NG is transported by HP pipelines connected to the MP pipelines operated by the distribution companies. At the Sines terminal, NG is received in liquid form (LNG) from gas tanker ships and pumped into intermediate storage tanks. After regasification, NG is compressed and injected into the HP network. At the underground storage facilities in Pombal, HP NG is stored in gaseous form in caverns created inside salt formations at depths of over 1000 meters.

32 Distribution NG is distributed in MP and LP pipelines under concessions and licenses granted by the Portuguese state. NG from HP NNGTN pipelines is transferred to MP branches through regulation and metering stations. These pipelines and the LP networks branching from them belong to distribution companies that deliver the NG to end users. In electricity, there is only one main distribution company. In NG there are several regional distribution companies.

33 Markets and consumption The NG markets are operated on an openmarket basis and require authorization from the Portuguese state. The NG is sold to end consumers by the suppliers, which buy and sell it freely on the open market or in bilateral contracts. After the opening of the NG market in Portugal, consumers who wish to do so are free to choose their NG supplier.
