Engineering Scope & Progress • Sites identification - use case , business case • Network studies due diligence • Concept designs per site – layout, 1-line, P+C • BESS specification • MV equipment specification • DERMS and APM specifications • Bid Documents • Costing and estimation • Commissioning 13

Project Timelines • Schedule subject to internal Eskom approvals and external approvals by DFIs and statutory bodies (DEA, etc) – Ph1 Bid Documents Finalisation 2018 Nov – Ph1 Enquiry Issued 2019 Q1 – Ph1 Enquiry Closes, Evaluated and Awarded 2019 Q2 – Ph1 Construction 2019 Q3-Q4 – Ph1 Test & Commissioning 2019 Q4 – Ph2 Enquiry Issued 2019 Q3 – Ph2 Enquiry Closes, Evaluated and Awarded 2020 Q1 – Ph2 Construction 2020 Q1-Q2 – Ph2 Test & Commissioning 2020 Q3 14

Challenges Experienced • Developing a decent BESS specification • Knowledge and skills for network studies • Defining Use Case and Business Case • Compilation of Bid Documents - Evaluation Criteria - Schedules - Internal Change Management (capacity guarantees, O&M, etc) • Statutory Approvals – EAs and land rights 15
