How much did the expansion of Bang Lang Dam cost?

Bang Lang is a clay-core rockfill dam across the Pattani River in Yala Province, built by Thailand's Electricity Generating Authority as part of the Pattani Hydroelectric Development. Construction ran from July 1976 to June 1981, and the dam was inaugurated on 27 September 1981. EGAT lists a 430-metre crest, an 85-metre height and a reservoir holding 1.42 billion cubic metres. The original World Bank completion report separates the $117.77 million actual hydroelectric development cost, including the dam, powerhouse and resettlement, from $15.76 million of separate regional transmission expansion; the broader loan project totaled $133.53 million, all in reported current-price USD equivalents. The original three generating units were rated at 72 MW in that report; EGAT now lists 84 MW for the operating plant.
