The reserve would be equivalent to about 15,513 MW-years of generation at 70percent CF, and the upper value of about 1000 Tcf would be equivalent to about 17,000 MW-years. This in turn corresponds approximately to 500 MW of generation over 20 years (the assumed economic life of a gas turbine or combined cycle plant). For this plan the cost of natural gas is estimated to be as shown below: US$ 0.68/GJ for protected gas supply to Ubungo 3.18 US$/GJ for additional gas The availability of Songo Songo gas depends on the delivery infrastructure, which consists of the wells, the gas processing facilities on Songo Songo Island (SSI), and the pipeline to Ubungo. The current pipeline capacity is 105 mmscfd which has been related from initial capacity of 90mmscfd. The Mnazi Bay gas with estimated proven reserve of 262TCF primary source for natural gas for power generation in Dar es Salaam, equivalent to about 4506.4 MW-years of generation at 70percent CF. This in turn corresponds approximately to 365 MW of generation over 20 years (the assumed economic life of a gas turbine or combined cycle plant). For this plan the cost of natural gas is estimated to be at price of US$ 4.74/GJ. The assumed use of available gas resource for existing plants and future projects in the 2012 PSMP is shown in table 3-21 below. This table indicates an inadequate gas supply to meet the present gas plants until 2014 when the Mtwara to Dar es Salaam pipeline will be available. It is assumed that all the available gas resource is confined for use in power generation implying that industrial gas needs remains at current level.
