SANTIAGO -(Dow Jones)- Chile's Quintero liquefied natural gas regasification plant will expand its capacity 50% to meet growing demand, El Mercurio newspaper reported Monday, citing a company official. Quintero, one of two regasification plants in Chile, is controlled by London-based BG Group PLC (BRGYY, BG.LN) and state oil and gas company Empresa Nacional del Petroleo, or Enap. With a $25 million investment, GNL Quintero, as the plant is known, will increase daily capacity by 5 million cubic meters so that it can deliver 15 million cubic meters of gas a day. Alejandro Palma, spokesman for the project, told the newspaper the plant is currently delivering 80% of its capacity daily, reaching 100% during peak demand. "We see strong demand in the market," Palma said. The LNG plant expansion will likely be ready in 2015, according to Palma. -By Carolina Pica, Dow Jones Newswires; 56-2-715-8919; carolina.pica@dowjones.com
