The second phase of the Strategic Environmental Assessment (SEA) for wind and solar photovoltaic (PV) energy in South Africa proposes three additional Renewable Energy Development Zones (REDZs) for wind and solar PV energy projects.
The REDZs support the responsible implementation of the Integrated Resource Plan (IRP 2019) that was recently gazetted by the Minister of Mineral Resources and Energy on 17 October 2019. Renewable energy projects that could be developed in these new REDZs have the potential to make significant contributions to mine rehabilitation and to support a just energy transition in the specified areas including where 12 GW of existing coal power stations are planned to be decommissioned by 2030. The IRP 2019 has identified the requirement for at least an additional 14.4 GW of wind and 6.0 GW of solar PV by 2030 amongst a range of other new-build capacity including coal, gas, imported hydro and storage. There is a distinct need for rehabilitating areas where existing coal power stations are expected to decommission and possibly repurposing these for a range of diverse economic activities including renewable energy deployment which can be “fast tracked” if within the new REDZs.
The outcomes of the second phase of the SEA for wind and solar PV energy in South Africa were presented to stakeholders at the CSIR, in Pretoria on 26th September 2019. This study was commissioned by the national Department of Environment, Fisheries and Forestry (DEFF). The two new REDZs for PV are in the Emalahleni and Klerksdorp areas and the third one, which focuses on wind energy, is located to the east of Beaufort West.
The identification of the new REDZs involved positive mapping (i.e. “pull factors”), which included factors such as the abundance of the existing wind and solar PV energy resources, access to the power corridors, and other technical criteria required for renewable energy facilities. This was followed by negative mapping (i.e. “push factors”), which included environmental features and areas that are sensitive to the placement of large-scale wind and solar PV facilities. Thereafter, an industry prioritisation exercise was conducted to ensure that the proposed areas are aligned with areas that the renewable energy sector identified as priorities for future projects.
The three new proposed REDZs were gazetted for public comment by the Department of Environment Forestry and Fisheries on 17 July 2020. Members of the public are invited to submit written comments or input, within 30 days of this date to the following address:
