SUNGAI SELANGOR DAM MINI HYDROELECTRIC POWER PLANT PROJECT

In May 2005, SMHB proposed the concept of developing a l0MW Mini Hydroelectric Power plant at the Sungai Selangor Dam to Syarikat Pengeluar Air Sungai Selangor Sdn Bhd (SPLASH). The proposal was accepted and a feasibility study carried out from September 2005 to December 2005.

The 110 m high Sungai Selangor dam was impounded in April 2003 and started spilling in April 2004. The average annual inflow is about 256 MCM. At full supply level, the head difference with the downstream plunge pool level is about 106m. Hence there is a potential to generate a small but significant amount of energy.

During the detailed design stage of the dam this was considered but was not implemented due to the non-firm nature of the power generated which depended on water released to regulate flows in Sungai Selangor. At the time, non firm power commanded a very low tariff rate. However, the recent change in policy by the government to support renewable energy projects by giving a better tariff now makes the hydroelectric project viable.

Due to the recent changes in the water supply industry, the developer has temporarily held back the next stage for detailed design and construction.
