1. What We Do

TZ-Songo Gas Dev & Power Gen (FY02)

Abstract*

The Songo Songo Gas Development and Power Generation Project aims at developing Tanzania's natural gas reserves, to produce least-cost power generation for domestic, and industrial use, in an environmentally sustainable manner. Components include: 1) developing the Songo Songo natural gas field, to supply gas to about 112MW at the Ubungo Power Plant - to be converted to gas firing under the project - and, to the Twiga cement plant. Works include construction...

Development Objective

The main development objective of the project is to develop Tanzania's natural gas reserves to produce least-cost power generation for domestic and industrial use in an environmentally sustainable and efficient manner. The project will promote private sector ownership and management of generation in the gas and power sectors. In addition, it will encourage increased access of the poor by developing financially sustainable rural energy schemes to presently unserved areas along the pipeline corridor.

    CommentBy December 16, 2010, TANESCO has connected 710 Households which comprises:- 113 HH on Songo Songo Island- 300 HH on the GridExtension part; and- 297 HH on the Wayleaves.Therefore Target is closed to being achieved.This Indicator was further reviewed in the light of the recent discussions on energy core indicators. In the review it wasclarified that this indicator as currently worded refers to Households. One household is equivalent to one TANESCO Customerconnection. However the current Results framework of the Project has several indicators, partially referring to Customers (i.e. =Households) but also to "Consumer" which are individuals within a Household. Thus within this ISR this indicator target value washarmonized in line with the Indicators wording referring to Households. Consequently the Target value was updated as follows:- RFrefers to 2.759 new consumers, which represents 484 Households in TZ (on average a HH counts 5.7 persons).- RF also refers toadditional 300 new customers (HH Connections) on Grid Extension part, and- 113 new Customers (HH Connections) on Songo SogoIsland.Thus the new and harmonizedHousehold target value should be 897 Households.
