Mitsubishi Corporation has awarded Voith Hydro the electro-mechanical equipment contract for the 174MW Asahan 3 hydropower project in Indonesia.

The project, will be operated by the state-owned utility Perusahaan Listrik Negara (PLN), is supported and financed by Japan International Cooperation Agency (JICA). 

Under the contract with Mitsubishi Corporation, Voith will be responsible for the design, manufacture and supply of two 87MW vertical Francis turbine and generator units, including the control system, complete electrical, and mechanical balance of plant equipment and a 150 kV switchyard. The project is scheduled to be completed in 2024 and will support Indonesia’s target to achieve a renewable energy share of 23% in the energy mix by 2025.

Indonesia’s hydropower potential is estimated at around 75,000 MW, with untapped resources concentrated on the islands of Sumatra, Java and Sulawesi. It is estimated that there is currently about 8 GW of economically viable undeveloped hydropower potential.

The electricity sector in Indonesia is controlled by the PLN, which has approximately 70% of the country’s 62.8GW installed capacity. According to PLN’s strategic plan (RUPTL), new capacity in the country will be delivered largely through several sources of energy, including a proposed 1 GW of new hydropower capacity.
