SongoSongo
gas-to-electricity project
The goal of the Songo Songo Gas to Electricity
project is to develop natural gas from the Songo Songo gas
field in Kilwa District to provide Tanzanians with a reliable
source of low cost electricity. The project will form the
basis of the development of gas industry and infrastructure
in Tanzania.
Gas-to-Electicity
Project
In October 1995, Ocelot Tanzania Inc. and TransCanada Pipeline
Limited (TCPL Tanzania Inc.), in partnership with the Government
of Tanzania (GoT), Tanzania Electric Supply Company Limited
(TANESCO) and Tanzania Petroleum Development Corporation
(TPDC), set out to create a company called Songas to implement
the Songo Songo Gas to Electricity Project. Songas has
developed Songo Songo gas field in Kilwa District,
Lindi Region, by constructing the gas processing facilities on Songo
Songo island and the pipeline network to transport natural gas to Dar es Salaam
where it will be used as the principal fuel
supply for five gas turbine electricity generators. The
pipeline will then continue to supply the Wazo Hill Cement
Plant. The project will produce reliable electricity for
the national grid and also bring gas to other industrial
users in Dar es Salaam.
Gas Field Development
The Songo Songo Gas to Electricity Project
will serve two onshore and three offshore natural gas wells
at Songo Songo Island. Natural gas from the wells is then
piped to a gas plant on Songo Songo Island.
Songo Songo Gas
Plant
Two 35 million cubic feet per day processing
units (dehydration and refrigeration) on Songo Songo Island
has been built to process the natural gas from the wells.
Any hydrocarbon liquids removed will be shipped to Dar es
Salaam or consumed on-site as fuel. The project has
brought
about an improvement in the Island's infrastructure by modernising
the airstrip and wharf and providing portable water and
power supply.
GAS TRANSPORTATION
After processing, the gas is transported
through a 25km 12-inch pipeline from Songosongo to Somanga
Funga, and from Somanga Funga through a 207km 16-inch pipeline
to Ubungo Dar es Salaam where natural gas has replaced liquid
fuel as feedstock in the generation of up to 115MW of electricity
for the national grid. A 16km 8-in pipe line has been extended
northwards to provide natural gas to the Wazo Hill cement
plant where it has replaced fuel oil as feedstock in the
manufacture of cement.
Project Developers
The Tanzania Ministry of Energy and
Minerals is responsible for coordinating the roles of TPDC
and TANESCO, as well as ensuring that the Project meets
the needs of all Tanzanians. The Ministry has been the principal
government negotiator on commercial arrangements and has
taken the lead on financing issues. TANESCO, the national
utility, owns and operates Tanzania's power generating and
distribution system. TPDC is the national oil company responsible
for exploration, promotion and development of oil and gas
resources in the country.
The major project sponsor was
originally TransCanada Pipelines. These were replaced
by AES Sirroco of USA, who in turn were replaced by CDC
Globeleq in 2003.
The other sponsor is Pan African Energy, formerly Ocelot
International, a gas development company, with operations
in several African countries. Project investors are AES,
Pan African Energy, TANESCO, TPDC, CDC, TDFL, EIB and World
Bank, the later two through the Government of Tanzania.
Project costs are estimated at US$ 350 million. The project
will be implemented by SONGAS, a local joint venture company
formed by Globeleq, TANESO, TPDC and CDC. Ocelot,
now PanAfrican Energy will operate the gas field on behalf
of Globeleq.
PROJECT SCHEDULE
The project had suffered considerable
delay in implementation. Financial closing was attained
on 11th October 2001. Construction of the pipeline
commenced in the year 2003 and was completed in may 2004.
The first gas reached Dar es Salaam in July 2004. The
project attained commercial operations in July 2004.
Project benefits
to Tanzanians
-
Meet the growing demand for electricity
in Tanzania using a domestic natural resources
-
Reduce the country's dependence on imported oil for electric
power generation
-
Provide an alternate, lower-cost and more reliable power
source
-
Permit the use of natural gas in industry as an energy source
or a chemical feedstock (e.g. fertilizer production)
-
Develop the infrastructure to boost exploration for oil
and gas
-
Provide power, clean water and associated economic benefits to Songo
Songo island and communities along the pipeline route and
-
Promote private investment in the energy sector
and contribute to government revenue through fees, taxes
and royalties;
-
Enable the Wazo Hill Cement
manufacturer to use natural gas as fule instead of
imported fuel oil
-
Enable Tanesco to diversify
their power generation options from the heavy dependence
on hydroelectricity

Songas
will develop the Songo Songo gas field in
Kilwa District, Lindi Region, construct gas
processing facilities on Songo Songo island
and transport natural gas to Dar es Salaam
via pipeline where it will be used as the
principal fuel supply for five gas turbine
electricity generators. |
