An Indonesian hydropower plant, Semangka HPP, has commenced commercial operations, which is expected to optimise the country’s energy structure.
Semangka HPP, which is located in South Sumatra region of Indonesia, generates power using discharge from the Semangka river.
The run-of-river hydroelectric plant has been developed to partially replace the energy generated by fossil fuel-fired power plants in the Sumatra Grid and supplement the share of renewables in the power generation mix.
Voith Hydro, a division of global technology group Voith, is said to have delivered the complete water to wire scope for the Indonesian hydropower plant.
The company delivered two generating units comprising of two vertical Francis turbines with a total output for 56.6MW, two 33.3MVA generators and two 33/40 MVA generator transformers.
Indonesia’s energy demand is expected to increase by 6.9% per year up to 2026, and the hydropower is expected to increase the share of renewables in the country’s total energy use to 23% by 2025 from approximately 13% in 2018, according to Voith.
According to PT Perusahaan Listrik Negara, the total new capacity in Indonesia shall be 56GW over the next ten years, out of which 8.3GW will be produced from hydropower facilities.
