HPC was formed in 2009 by Banpu Power Limited (BPP), Ratchaburi Electricity Generating Holding Public Company Limited (RATCH), and Lao Holding State Enterprise (LHSE), to develop and operate a 1,878 MW lignite mine mouth power plant, commonly called the ‘Hongsa Power Plant’. Upon its scheduled completion in 2016, Hongsa Power Plant will become Lao PDR’s highest-capacity power plant, providing a sustainable source of energy for both Laos and Thailand.
