Shaker, Tanzanian president break ground on Rufiji river dam: Electricity Minister Mohamed Shaker and Tanzanian President John Magufuli broke ground on the 2.1 GW Stiegler's Gorge Hydroelectric Power Station in Tanzania that will be constructed by a joint venture between our friends at Elsewedy Electric and Arab Contractors, reports Masrawy. The project is slated for completion sometime around June 2021. The JV signed the USD 2.9 bn construction agreement with the Tanzanian government late last year. The project had previously prompted concerns from conservation groups for its potential to endanger the nearby Selous Game Reserve.
