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
Characteristics
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.
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
