We would like to inform you that the Amended Environmental and Social Impact Assessment Report for the BOSA project is available for comment from 23 June 2020 until 24 July 2020. This amended ESIA Report is now available for public comment for a period of 30 days.

In 2018 Environmental Authorisation was granted for the proposed 400kV transmission powerline stretching between the Mahikeng area in South Africa and the North of Gaborone in Botswana. The project entails the installation of 210 km of 400 kV transmission line to link the Isang substation near Gaborone in Botswana and the proposed Watershed B substation near Mafikeng in South Africa, of which 145.8 km is in South Africa and 63.7 km in Botswana. The application for environmental authorisation is for a 1 km wide corridor. The South African Power Pool (SAPP) appointed Aurecon South Africa (Pty) Ltd (“Aurecon”) to conduct the ESIA process. The ESIA process must meet national requirements in Botswana and South Africa. Aurecon is managing the overall ESIA process to ensure compliance with the funder, DBSA/IFC, requirements. Subsequent to the authorization, the section closest to the proposed Watershed substation had to deviate from the authorised zone to align with the Pluto line that will join the substation from the east. Please see the attached letter for more information regarding the amendment.

Due to COVID-19 hard copies of the amended Environmental Impact Assessment Report are not available, but electronic copies of the report can be downloaded from:
