2 Delivering South Africa s First Project Financed Run of River Hydro Power Plant: The Neusberg Project

3 Outline of presentation Introduction Development Construction Civil Works E&M Works

4 Introduction First run-of-river Hydropower scheme developed under REIPPP to achieve Commercial Operation Round 2 project that achieved Financial Close in May 2013 Construction started in June 2013 Achieved Commercial Operation on time and budget on 31 January 2015 Generating 10.8 MW with 90 m3/s of water at m head 72 GWh of base load energy per year with a capacity factor of 82%

5 Development Site identified in 2009 by Mulilo Renewable Energy Hydro Tasmania joined in 2011 and provided technical guidance (Energy Modeling, Feasibility Studies, high level designs, etc) and proved the project to be viable Awarded preferred bidder status in Round 2 of the REIPP program in 2012

6 Development Project Finance According to the International Energy Agency: Obtaining finance for small hydropower projects is hard Involve large upfront investment, regarded as high risk compared to thermal projects Investment relatively small, limited recourse project financing not feasible Small hydro typically not of sufficient scale and therefore traditionally delivered on balance sheet

7 Development Project Finance Neusberg project demonstrated: limited recourse project financing is possible for small hydro projects Opportunity exist for the development of small hydro throughout Africa with the use of limited recourse project finance

8 Development - Contracting Contracting strategy that provide certainty on cost, time and quality i.e. EPC wrap Split EPC contract structure (Civil and E&M) with Coordination and Interface Agreement EPC Contractors also own 25% of the Project

9 Project participants Lenders: Nedbank & IDC Hydro Tasmania South Africa (25%) Hydro 1 SA (25%) Old Mutual (35%) Community Trust (15%) funded by IDC Civil Works EPC E&M Works EPC OEM WOM Maintenance Asset Management Services Civil Design Turbine supply

10 Hydro Tasmania Australia s largest producer of renewable energy (8,500 GWh/year from hydropower) Built and maintains a portfolio of 30 hydropower stations and 50 major dams Total installed capacity of 2653 MW Oldest operational hydropower station in the portfolio reached its centenary late in 2014 Brought 100 years of experience in developing and operating hydropower plant in Australia to South Africa.

11 Construction - Overview Off-take weir and 130m of inlet canal Inlet structure fitted with a radial gate 1400 m of open canal waterway Forebay structure with gates, stoplogs and conduits Partially buried powerhouse 3 off 4 MW horizontal Kaplan turbines, 6.6 kv synchronous generators, 6.6/33 kv generator transformers 300 m long tailrace canal 21km long 33 kv transmission line to the Eskom distribution network

41 Hydro Power Plant 108 years of hydro history 250 power stations installed in 40 countries 500 MW of generation installed or designed 2 manufacturing facilities (France and South Africa) 5 to 8 projects per year 100 % Hydro specialists The only one hydro turbine manufacturer based on the African continent (office and manufacturing facility)

42 HPP History 2015 Neusberg Project is commissioned (January 2015) Take over by Pierre Pisterman, Great grand son of Louis Tinchant 2014 Hydro Tasmania involvement 2010 Commissioning of a 22 MW hydro power plant in DRC 2006 Development in South Africa -> African Market 1991 International expansion 1983 First hydro power plant greater than 1MW Commissioned in France 1972 Patrice Pisterman created Hydro Power Plant (HPP) 1906 Louis Tinchant, great-grandfather of Pierre Pisterman (CEO) builds his first hydro station

43 HPP Industrial Layout In order to be cost efficient, HPP proposed an adapted industrial layout in order to optimize the costs, logistics and the site works. As a result, only the high added value components are done in France and Europe such as : Complete detailed design and specifications Blade castings and shaft forging Gearboxes

44 HPP Industrial Layout In order to be cost efficient, HPP proposed an adapted industrial layout in order to optimize the costs, logistics and the site works. As a result, only the high added value components were done in France and Europe such as Hydraulics and lubrications units Control systems Alternators and AVR s High Voltage equipment

45 HPP Local foot-print All others components and / or services were performed in South Africa thanks to our partner WD Power in Johannesburg Turbine Casings Final assembly and Factory testing Packing and logistics
