A consortium composed of Qatar Petroleum, ExxonMobil Power Ltd. and Total Gas & Power Venture is mulling to build a 500-megawatt combined heat and power (CHP) plant at the South Hook liquefied natural gas (LNG) import terminal in Wales. The terminal is said to be the biggest regasification hub in entire Europe.

"The proposed CHP plant will have an installed capacity of up to 500 MW and produce sufficient electricity to both meet the existing LNG terminal's power needs and to export surplus electricity," the three project partners said in an environmental impact assessment report to the UK's National Infrastructure Planning authority.

Britain is one of many nations dependent on Qatar's LNG output, which it supplies through the South Hook terminal.

The CHP plant, according to the three partners, will generate electricity sufficient enough to run the South Hook terminal, with the option to export power surplus to the National Grid.

The consortium is expected in the first quarter 2013 to submit a formal application for the CHP plant project, UK's National Infrastructure Planning authority said.
