A joint venture led by Tractebel Engineering with Japan’s NEWJEC, and local consultancy PT Connusa Energindo, has been appointed project implementation consultant for the Bakaru I and II hydropower projects on the river Mamasa on the island of Sulawesi by Indonesia’s state utility PT Perusahaan Listrik Negara (PT PLN).
The project involves the rehabilitation of the 128 MW Bakaru I plant and its extension by 144 MW (referred to as Bakaru II) with the construction of a new headrace tunnel, pressure shaft/tunnel and powerhouse parallel to the existing structures. The existing switchyard also has to be modified. The Bakaru I run-of-river plant, which was commissioned in 1991, is capable of generating 1030 GWh/year under an operating head of 320 m.
The 60-month contract, which is valued at around US$ 14.2 million, covers the preparation of the detailed design and procurement of the civil and E&M contractors, and supervision of the contractors through to commissioning, according to a contract award notice published on 15 July on the website of Germany Trade and Invest (GTAI). The consultant will also support PLN in project execution in line with international best practice and World Bank guidelines with respect to social, environmental, and health and safety aspects. The consultancy services will be financed from a special grant fund provided by the German Federal Ministry for Economic Cooperation and Development.
