Changes to SAHRIS!

The South African Heritage Resources Information System (SAHRIS) has undergone a generational upgrade and restructure. These changes to the site include, but are not limited to:

  • A new & modernised look and layout
  • Improved site usage flows with respect to applications and content creation
  • Improved site performance and stability

Launch for the new version of SAHRIS occurred on Monday the 30th of October 2023.

INTEGRATED HERITAGE IMPACT ASSESSMENT (HIA) ON PORTIONS OF THE FARM SLURRY 96 JO FOR THE PROPOSED STURDEE ENERGY PPC SLURRY SOLAR PROJECT, NGAKA MODIRI MOLEMA DISTRICT MUNICIPALITY, NORTH WEST PROVINCE

Expanded_Motivation: 

CES was appointed by Sturdee Energy to undertake the environmental impact assessment process (EIA) for the proposed PV Solar Plant at the PPC Slurry Operation on Portions of the farm Slurry 96 JO, Ngaka Modiri Molema District Municipality in the North West Province (hereafter referred to as the “Sturdee Energy PPC Slurry Solar Project”). Two site alternatives, Alternative 1 (preferred) and Alternative 2 have been identified for the project. For the integrated HIA, an AIA and a PDA1 were commissioned. The location of the solar PV plant has been optimized within the allocated land parcels provided by the Client. A Medium Voltage (MV) overhead line (OHL) has been proposed to interconnect the PV plant to the PPC main distribution substation on each site. The following infrastructure components are proposed: - Mounting Structures. The structures chosen are oriented in a North-South axis along a single-axis horizontal axis system, which rotates the panels to orient them, at the sunrise, to the east and, at the sunset, to the West. The reason for this selection was done to enhance the total yield over the life-span of the PV system. On average this system will yield +-15% more energy (kWhrs) at the point of connection every year for the life of the plant, as compared to a fixed-tilt system at an angle of 25 degrees with no tracking. There is an additional capex associated with the tracking system due to the additional control, monitoring and associated tracker system requirements, however the Levelised Cost of Electricity (LCOE) when considered over 20 years will be significantly lower than a fixed-tilt equivalent with all other variables held constant. This system thus has an advantage of providing a significantly lower LCOE owing to the greater solar PV yield. The tracker layout has been optimized to reduce shading significantly. This is achieved by spacing rows at a pitch of 6.5m apart thus preventing majority of inter-row shading losses and reducing back-tracking requirement. Where land is constrained, such as the De Hoek site, we had to reduce pitch distance to 4m to allow the full PV plant DC capacity to fit. - Buildings. • Substation & control room on site • The building will be air-conditioned to maintain an adequate temperature-controlled environment for the electronic devices that will be housed within i.e. UPS, park controller, tracker controller, MV switchgear, etc. • Building will contain fire extinguishers, PPE, toolbox, spares, and working table for on-site personnel - Civil Works All civil works are designed to capable of withstand a 100-year storm event, including the effects of water, extreme winds and other natural disasters, without flooding, erosion, settlement or damage. - Electrical Connections For the interconnection with the existing PPC substation it is required to design, build and commissioning a new 11kV or 6.6kV overhead line (OHL) capable of evacuating up to 10MVA on a continual basis. Eskom Distribution standards and specifications will be used as the reference requirements to design, construct and commission the MV overhead lines.
