The Bakun Dam is an embankment dam located in Sarawak, Malaysia on the Balui River, a tributary or source of the Rajang River and some sixty kilometers west of Belaga. As part of the project, the second tallest concrete-faced rockfill dam in the world would be built. It is planned to generate 2,400 megawatts of electricity once completed. The purpose for the dam was to meet growing demand for electricity. However, most of this demand said to lie in Peninsular Malaysia and not East Malaysia, where the dam is located. Even in Peninsular Malaysia, however, there is an over-supply of electricity, with Tenaga Nasional Berhad being locked into unfavourable purchasing agreements with Independent Power Producers. The original idea was to have 30% of the generated capacity consumed in East Malaysia and the rest sent to Peninsular Malaysia. This plan envisioned 730 km of overhead HVDC transmission lines in East Malaysia, 670 km of undersea HVDC cable and 300 km of HVDC transmission line in Peninsular Malaysia. Future plans for the dam include connecting it to an envisioned Trans-Borneo Power Grid Interconnection, which would be a grid to supply power to Sarawak, Sabah, Brunei, and Kalimantan. There have been mentions of this grid made within ASEAN meetings but no actions have been taken by any party. Bakun Dam came online on 6 August 2011. (via Freebase)
