ZANZIBAR – The World Bank Group has approved US$142 million for the modernisation of Zanzibar’s electricity network and the integration of renewable energy and allow the electrification of 400,000 people in this Indian Ocean archipelago.
Of this funding, US$117 million represents a credit from the International Development Association (IDA) while remaining US$22 million is a loan from the Clean Technology Fund (CTF), which is also providing a US$3 million grant.
The project is being implemented by the Zanzibar Ministry of Water, Energy and Minerals and Zanzibar Electricity Corporation (Zeco), the company that transmits and distributes electricity in this autonomous entity within the Republic of Tanzania. The Zesta project marks a real milestone in Zanzibar’s energy transition.
As part of Zesta, the Zanzibar government plans to build the first utility-scale solar photovoltaic power plant in the Indian Ocean archipelago and the 18 MWp facility will be built in the Makunduchi area, southeast of the main island of Unguja. The state-owned company Zeco will also build an interconnection line to the grid, at a total cost of US$16.5 million.
The Zanzibar authorities also plan to equip the future solar photovoltaic plant with a 40 MWh battery storage system, which will be connected to a 132 kV substation to stabilise the archipelago’s power grid.
“The project’s investments will also contribute to broader gender and climate resilience objectives. The project will support improved career opportunities for women in Zanzibar’s energy sector and help build climate resilience in terms of both mitigation and adaptation, supporting Zanzibar’s climate change strategy,” says Mbuso Gwafila, World Bank Senior Energy Specialist and Task Team Leader.
“Investments under this component are also expected to increase household resilience to climatic events such as floods and pandemics such as Covid-19”World Bank
The grid is also supported by a submarine cable that connects the main island to the Tanzanian mainland with the 132 kV line capable of carrying 45 MW of electricity.
Power grid modernisation
Zesta is also upgrading the Unguja power grid.
According to the local authorities, this other project component will improve the reliability of electricity supply, reduce losses and extend access to electricity to unserved communities and vulnerable households.
The Washington, D.C.-based financial institution is also supporting the construction of the first 132kV high-voltage transmission backbone infrastructure, including 100km of transmission line between the north and south of Unguja, to evacuate power from the solar photovoltaic plant, and to allow for the future integration of power generation to meet the growing demand for electricity on the island.
