Royal HaskoningDHV is implementing four mini hydropower plants along the Merawu River (pictured) in Central Java, Indonesia, to provide a sustainable source of energy for 11,000 households in several villages.
The project consists of four cascaded run-of-river plants, with 6 MW at Kerekan and Pandensari, 2.4 MW in Watupayang and 1.2 MW in Tempuran. The powerhouses will each contain several turbines and a transmission line will connect them to the local 20 kV grid.
The projects represent the first phase in the agreement with TIRASA – a pioneering energy investment company in Indonesia – to develop small scale hydropower plants for about 400,000 people. Now preparing detailed design and tender documents for the four plants, the next stage will involve tender assistance and construction management. The $30 million programme expects a return on investment of seven years.
Suryana Padma, president director of TIRASA, said: ‘This is the first stage in our programme to provide a total installed capacity of 100 MW by 2018. These hydropower plants provide a sustainable solution to the lack of supply experienced in Indonesia.’
