BACKGROUND
Cameron Highlands Power Stations consists of two hydro electric schemes, the upper Cameron Highlands Hydro Electric scheme and the lower Batang Padang Hydro Electric scheme. These two schemes are spanning three states in peninsular Malaysia. The schemes started from the Plauur diversion intake at the border of Kelantan and Pahang, across Cameron Highlands district in Pahang and ends at the tallrace of Odak power station in Perak. The station operated since 1959 until today as a hydro electricity contributor to fulfill electricity demand. After operating more than 40 years, Life Extension Project (LEP) of this station was executed to improve station availability and efficiency. Under this project, the old systems are replaced with new technology employing best practices in power generation.
Sultan Idris II Power Station (Woh Power Station) is an underground power station with natural ground level, 900 feet below surface. The Power Station is located at the 7th mile road to Tanah Rata from Tapah. The Machinery Hall and Lower Valve Chamber were excavated out of solid granite. The Powerhouse is equipped with three vertical shaft Francis turbines running at 600 rpm with a static head of 1380 feet. The turbines are directly coupled to vertival shaft alternators delivering 50 MW at 0.9 power factor. Water is mainly supplied from Jar Reservoir via the Menglang Tunnel that is 9 miles long. Three small side stream intakes are situated along the line of Menglang Tunnel to waters from the Sungai Woh catchments. Menglang Tunnel supplies water to the two high-pressure penstocks of the Station. The water is led away from the turbines through a tunnel. This trailrace tunnel is one mile long and has an equivalent diameter of 16 feet.
