The RGoZ has obtained funding from the World Bank to implement the Zanzibar Energy Sector Transformation and Access (ZESTA) Project to address key challenges in the sector arising from sole reliance on the limited submarine transmission capacity from mainland, which will, without additional supply options, result in supply rationing and load shedding during the peak demand period in Unguja. The other challenge in the sector is inadequate distribution system capacity that is causing high technical losses and preventing reliable and efficient supply and the acceleration of electricity access scale-up. The ZESTA Project thus aims to expand access to reliable and efficient electricity services and to scale up renewable energy generation in Zanzibar.

The proposed distribution network investments include the refurbishment of existing 11kV substations and the replacement/upgrade of existing 11kV underground cables within the Stone Town area. Construction activities, such as trench excavation and trench compaction, may have negative impacts and risks on cultural heritage assets that are near the construction sites, especially the old buildings that have weak structures. Other potential impacts include noise, dust, closing of roads and alleyways, restriction of religious activities, loss of livelihoods, etc. Construction activities may also expose the public and contractors’ workers to safety risks such as collapsing buildings and falling in uncovered trenches.
