Contract for the 174 MW Asahan 3 hydro plant is awarded

23 December 2020

Voith Hydro has been awarded by Mitsubishi Corporation the electro-mechanical equipment contract for the Asahan 3 hydropower project in Indonesia, which will be operated by the state-owned utility Perusahaan Listrik Negara (PLN). The project is supported and financed by Japan International Cooperation Agency (JICA).

Voith will be responsible for the design, manufacture and supply of two 87 MW 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 renewable energy share of 23% in energy mix by 2025.

Voith has to date put into operation 200 MW of hydropower in Indonesia through 20 small and medium hydro projects, and provided project management, onshore supplies, services, spares, repair and maintenance, and modernisation works for several hydropower projects in the country.

Indonesia’s total hydropower potential is estimated at around 75 GW, 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 state-owned utility PT Perusahaan Listrik Negara (PLN), which has approximately 70 % of the country’s 62.8 GW installed capacity. According to PLN’s strategic plan, new capacity in the country will be delivered largely through sources of energy that include a proposed 1 GW of new hydropower capacity.
