Sion is MEL’s pioneer hydropower project which is a collaboration between MEL’s subsidiary – PT Citra Multi Energi, and a Japanese engineering company. It has an operating capacity of 10MW and has been operating since 2020. PLTM Sion is situated at the Aek Simonggo River which boasts an extensive catchment area of 279km2 and annual rainfall of 3,500mm
Prior to construction, this project was reviewed by foreign experts from USAID, as well as from consultants from SWECO in Norway for its feasibility study and Chodai for its basic and detailed designs.
Its construction was carried out by an Indonesia-Japan foreign investment contractor under the guidance of a Japanese management consultant. Sion Hydropower Plant’s generator consists of 2x Voith Fuji turbines with a maximum installed capacity of 5MW each.
This project is a recipient of the Joint Crediting Mechanism from the Japanese government for its contribution to the reduction of greenhouse gas and carbon emissions.
Following Sion’s completion in 2020, we swiftly embarked on our next project, Pungga, which is located at the AEK Pungga river in the same region. It has an operating capacity of 3.5MW and will be able to provide an 19.5GWh of electricity annually, capable of powering 2,000 households.
This project was contributed by Stream Hydropower, and consists of 1 turbine from Gugler. After construction began in 2023, AEK Pungga is slated to be completed in 2025.
On schedule to start construction soon, Tomuan is located in the Asahan region in North Sumatra and operates at a capacity of 14.7MW. It also has a head height of 288.15m, making it one of the biggest heads among our projects.
MEL has commissioned a Chinese contractor for the construction and will operate with 2 turbines. With the purchasing power agreement (PPA) obtained for this project, construction will start in 2025 and be completed in 2027.
