The objective of the project is to generate electricity to feed into the National Grid by installing solar power plants (and associated substations). The proposed plants are regarded as a listed activity in terms of the Environmental Impact Assessment Regulations released on the 18th of June, 2010 and promulgated on the 2nd of August, 2010, and thus require an Environmental Impact Assessment. SiVEST Environmental Division has been appointed as independent consultants to undertake the EIA on Eskom‟s behalf. The proposed project involves the construction of a 50 MW PV/CPV and 100 MW CSP plant. Due to the licensing process that needs to be undertaken by Mainstream, it is likely that the project will be phased with the construction of the PV occurring first followed by the CSP project. The construction of a CSP plant requires the use of large amounts of water. In order to reduce this impact on the environment, the project proposes the use of waste water from the De Aar Municipal Waste Water Treatment Works as opposed to using fresh water from a borehole or river. The proposed project is required to improve electricity supply to the Eskom Grid and to assist in achieving the Government‟s mandate for the establishment of renewable energy generation facilities. The proposed project involves the construction a CSP and PV/CPV plant. Layout alternatives have been investigated and these relate to the location of the associated infrastructure on the site. These are illustrated below: MAINSTREAM RENEWABLE POWER prepared by: SiVEST Environmental Draft Environmental Impact Report Revision No. 1 23 May 2011 Page 5 C:\Liesl 2011\PROJECTS\CSP 10 May 2011\De Aar Draft EIR rev 1 - 13 May 11 LK.docx Figure i: Site layout alternatives The site is characterized by shrublands which are generally dominated by dwarf karoo shrubs and grasses. The site was found to be in a disturbed condition, most likely due to sheep grazing which is known to take place in the area as well as construction activities associated with the secure care centre. Several specialist studies were conducted for the EIR Phase as stipulated in the Plan of Study for EIA. These included: . Biodiversity (including fauna, flora and avi-fauna) Assessment . Surface Water Impact Assessment . Groundwater Study . Noise Impact Assessment . Visual Impact Assessment . Heritage Assessment . Socio-economic Impact Assessment (incorporating tourism) . Waste Management Plan .
