An Alstom consortium is to build a new, $1bn coal-burning generating unit at a power plant in Thailand.Â Â
It will be the first "ultra-supercritical" power plant burning lignite, a type of coal, in Asia, according to Alstom.Â
Alstom, with Japanese trading company Marubeni Corporation, have signed an agreement with the Electricity Generating Authority of Thailand (EGAT) to build the new unit at Mae Moh power plant. Alstom has a $560m share of the $1bn EPC contract.Â
This new unit will replace existing four older units. Upon completion in 2018, it will produce 600MW of electricity.Â
Existing units in the Mae Moh Power Plant were originally equipped with Alstom boilers.Â Â
Alstom said the new unit will be just under 20% more efficient in producing heat than the current units, and will cut CO2 emissions per unit of fuel down by 20% on current emissions.Â Â Â
Mae Moh in northern Thailand currently generates 2,400MW of coal-fired power annually.
