Sarawak Energy chief executive officer Torstein Dale Sjotveit was quoted by The Sun Daily as saying that the company will invest MYR3bn ($976m) for this project that would be finished in stages from late 2014 to late 2015.

"Sarawak Energy has now signed firm agreements with Tokuyama, Asia Minerals, Press Metal, OM Holdings and PLN (Persero) from Indonesia for a combined total of 1,800-megawatts (MW) and also term sheet agreements with a further three customers for an additional 600 megawatts," Sjotveit said.

"This means that the entire firm output of both Bakun and Murum dams have been sold to solid industries at attractive prices and with reasonable inflation clauses."

The Murum project, which was now 75% completed, is expected to commence production by early 2014, Sjotveit added.

Another new big project, the Balingian 600MW coal fired plant in Mukah area was due to commence construction in 2013 with production to begin in late 2015.
