  • Future Grid map by 2035

  • Somanga 250MW CCGT Power Plant

  • Background

    The project is earmarked in the national 2012 Power System Master Plan. It is planned to add 250MW in the national grid.

    The proposed power plant will utilize local natural gas from the Mtwara Dar es Salaam main pipeline.

  • Background

    In the spirit of efficient utilization of local energy resources, the proposed power plant will utilize a Combined Cycle Gas Turbine (CCGT) technology.

    The project was chosen to be a pilot project to be implemented under Public Private Partnership (PPP) arrangement. All preparatory works are financed by the World Bank.

  • Location

    The Pre-feasibility study has indicated that the proposed plant has to be relocated from Mkuranga area, Pwani District to Somanga, in Kilwa District. The Kilwa site is near to the sea, gas infrastructure, Dar Mtwara road and proposed substation.

  • Characteristics

    Plant Cooling Water will be

    sourced from the sea, with a once-through cooling method.

    The generated power will be evacuated through a 400kV substation to the proposed main 400kV Mtwara Kinyerezi Transmission line.

  • Intention

    The project is planned to be implemented under PPP arrangement with an intention to:

    expedite project implementation; quality Improvement; access to new sources of private

    capital; and allocate risks to the party (private

    party) best able to manage the risk.

    Characteristics

  • Process

    For the competitive process, prior to start of EPC implementation works will follow the following route .

  • Conclusions

    1. Tanzania has decided to develop IPP power projects using competitive methods

    2. This is the first project to be developed in the competitive

    mode

    3. Interested Investors are invited to participate in the

    process

    4. More projects under way for Hydro, Coal, Gas, Solar, etc
