Under the Environmental Management Act (Act 7 of 2007) section 27 the activity described as "energy distribution, transmission and generation" requires an Environmental Clearance Certificate (ECC) as it is a listed activity. In 2022, NamPower obtained the Environmental Clearance Certificate for the operation and maintenance of the Zambezi Transmission Station. NamPower would therefore like to apply for the renewal of the ECC for the Zambezi Transmission Station in order to comply with the Environmental Management Act (Act 7 of 2007) and its regulations. The substation consists of low, medium and high voltage yards as well as storerooms, control rooms and offices. It is also houses the converter station for the 350k Zambezi - Gerus HVDC line. A Converter Station is required at the transition point between HVDC and High Voltage Alternating Current (HVAC) to enable distribution or further transmission. There are three transmission lines connecting to Zambezi Substation namely: 350k Zambezi - Gerus HVDC line; 220kV Zambezi - Sesheke line and the 66kV Zambezi – Katima line. The substation covers a footprint of 19.5 hectare. Figure 1 below shows the locality map for the Zambezi Substation.
