The objective of the project is to provide sufficient and reliable electricity at least cost through
(ii) strengthening the transmission networks in Beira city an along the Beira Corridor; and
(ii) installation of a LDC at Quelimane to serve the Central and North Regions.
1.In spite of the abundance of energy resources, access to modern forms of energy particularly of electricity is very low: it is about 6.3%, which is mainly the result of insufficient investment in the sector to expand and rehabilitate the aging and dilapidated electricity infrastructure. Despite experiencing current surplus in power generation capacity, the country cannot expand access without making investment in power transmission and distribution system.
2.During 2003, two thousand three hundred six outages (about 6 outages per day) were reported which resulted in 6491 MWh of non-supplied energy for Southern, Central and Northern regions. Since 70% of the interruptions occurred in the Central and Northern Region, the non-supplied energy for Central and Northern region, where the Electricity IV is to be located, was 4483 MWH. According to the average LRMC rate of US Cents 9.1/kWh, the value of the non-supplied energy in monetary term was equivalent to US$ 407,953. However, as indicated in Mozambique System Reliability-Planning Criteria-Final Report the consumers in perceive the value of the non-supplied energy at USD 1.5/kWh. Taking into account the perceived value of the non-supplied energy, the total cost of the non-supplied energy to the society is USD 6.73 Million.
3.Further, electricity demand is forecast to grow to 150-200 MW in the central and northern region in the year 2020. The existing 110 kV lines and substations that were installed in the seventies had surpassed their useful lives, will not be able to cope up with the increased demand in the region.
4.In view of the above, the Electricity IV project has been conceived as a dependable solution to: improve the electricity access, deliver energy to meet long-term demand, reduce power supply interruptions and improve the quality of supply to consumers in the project area.
5.The proposed project, all components of which have been studied at feasibility level, involves establishing a 220 kV power transmission line with power transfer capacity of 150 MW and substations at Chibata and Dondo-an industrial town in vicinity of Beira. The power transmission system will eliminate the power supply interruptions as above indicated. The other project component is the rehabilitation of 110 kV substations at Beira, Dondo, Mafambeisse and Lamego that were installed in seventies and that they have outlived their useful lives. Without through rehabilitation, their lives cannot be extended. In order to minimize outage period during rehabilitation, through planning will be necessary.
6.Construction a 220 kV transmission line is the least cost option when compared with the alternatives such as
(i) rehabilitating 110 kV line and
(ii) building 400 kV single circuit line in place of 220 kV single circuit line. Being in operation for over 30 years, rehabilitating 110 kV lines is going to be imprudent since it will entail 110 kV lines out of service for several months and cause wide spread disruption of supply and discontent to consumers. Due to imposed inconvenience on public, this option is rejected. On the other hand, investment in constructing 400 kV line being about 1.5 times the investment in constructing a 220 kV line is not supported by the long-term demand in the project area. In sum, the Electricity IV project is the least cost solution compared to the alternatives.
7.The design of the proposed project has incorporated lessons learnt from the implementation of past Bank Group financed projects in Mozambique's power sector. One of the lessons learnt is that realistic implementation schedules should be drawn, taking into account the institutional capacity of the executing agencies and difficult terrain in the country.
The project is located in the Sofala and Manica Provinces in the central part of Mozambique, with the new transmission line extending from the existing Chibata 220 kV substation to the site close to the existing Dondo substation near Beira. The project area covers the Beira Corridor development Zone, which is one of the economic development corridors being promoted within the SADC region. The project will improve electricity supply to the port city of Beira and surrounding areas, Dondo, Lamego, Mafambisse, Gondola, Namatanda, Chimoio. In addition, the Distribution Network component will cover growing agricultural centres of Muanza, Chupanga, Maringue, Gorongosa-chitengo in the Sofala Province and Sussundenga, Chigodore, Catandica, Macossa, Mpatanguela, Cachicamba and Mandie in the Manica province.
The total population of the project area is about 2.9 million, of which only 5.3% has access to electricity. The project on completion will improve electricity supply to an estimated 79,364 existing customers, (including households; schools, health service facilities and water supply facilities, mills and shops/restaurants; and commercial plantations, fishery processing installations, industries such as cement plants, steel works, railway facilities on the Beira corridor. The project will supply the additional electric power (about 5MW) required for the expansion of water supply to Beira - currently under construction. The project will also secure the supply of grid electricity to an estimated 38,000 new customers including households, hospital, schools, water supply installations and shops, in un-served outlying suburbs and rural communities in the two provinces. In particular, synergy will be established with the ADB financed Beira Corridor Health project, which involves rehabilitation, reconstruction and upgrading of 15 health centers in the project area. In addition, the project will connect 1440 new households, 496 commercial customers and 54 irrigated commercial firms under the OPEC Fund financed component. This will improve the level of access to about 9.5% from the current level of 5.3%.
