(Lysaker, 10 December 2008) The Portuguese energy company REN Trading signs up to trade carbon products at Nord Pool from December 2008. REN Trading is a Portuguese company, totally owned by REN SGPS, the group that owns and operates the only electricity transmission network in mainland Portugal and the national high-pressure gas transmission network. In connection with the phasing out of the long term Power Purchase Agreements (PPAs), the Portuguese Law has stipulated that PPAs which have not been terminated should be managed by REN Trading, created by REN SGPS in June 2007. REN Trading manages the two remaining PPAs, one with Tejo Energia, in relation to the 600 MW coal fired power plant in Pego, and the other with Turbogás, in relation to the 990 MW natural gas combined cycle power plant in Tapada do Outeiro. The objective of REN Trading is to maximize the revenues from selling electric energy in the markets and to minimize the production costs. Being a regulated company, the benefits obtained through this activity are shared with the consumers, according to a methodology defined by the National Regulatory Entity, ERSE. Fernando Santos, director at REN Trading comments, “It is for us a great honour to be the first Portuguese member at Nord Pool. REN Trading is a small but very active company in the power and CO2 business in Portugal. We are responsible for trading CO2 licences for the two power stations referred above and I am sure that being a member of Nord Pool is an important step to make good business and to help us to reach our company objectives.” About Nord Pool ASA and NASDAQ OMX Commodities Nord Pool ASA and NASDAQ OMX Commodities provide access to the world's largest power derivatives markets and one of Europe's largest carbon markets.
