Indonesia has substantial geothermal energy potential, estimated to be around 28,000 MW, making it the second largest in the world (2nd only to USA in terms of Geothermal potential). Despite this, the utilization of this resource remains relatively low, with only a small fraction currently being tapped.
WHY RUN-OF-RIVER HYDROPOWER PLANT?
Hydropower works on a stunningly simple principle: water flowing through a dam turns a turbine, which drives a generator to produce electricity. In recent years, however, numerous studies have outlined the downside of building large reservoirs – upsetting the natural flow of the river, killing biodiversity, flooding large acres of land that uproots communities and locals and changing weather patterns. Not really under the jurisdiction of clean, green energy.
Run-of-river hydropower, on the other hand, uses the natural head and flow curve of the river. Diverting water upstream, usually through a pipe, to a downstream turbine to generate power before it reenters the stream. The natural flow of the river stays in tact. There is minimal environmental impact and zero carbon emissions. Also remote areas, which are genuinely affected by low power supply and poor infrastructure, can benefit from renewable energy generation through run-of-river plants.
Through TOBA, we construct and operate PLTS Tembesi located in Batam which is a solar power plant on top of Waduk Tembesi that generates 36MW of electricity.
