Southern African Power Pool
South Africa represents 81% of SAPP in 2010 and will remain at 77% of SAPP in 2025
![Page 17: The Energy Integration in Southern Africa Jean-Pierre Favennec IFP Professor – Consultant Johannesburg – December 2, 2010](https://reader030.vdocuments.site/reader030/viewer/2022032701/56649c875503460f9493f6ce/html5/thumbnails/17.jpg)
The Integrated Resource Plan : Context and Description
Obligation after National Energy Act of 2008 Long term electricity capacity plan to develop a
sustainable electricity investment strategy for generation capacity and transmission infrastructure for South Africa over the next 25 years. Demand-side management (DSM) Pricing Capacity provided by all generators (Eskom and independant
power producers) Environment
![Page 18: The Energy Integration in Southern Africa Jean-Pierre Favennec IFP Professor – Consultant Johannesburg – December 2, 2010](https://reader030.vdocuments.site/reader030/viewer/2022032701/56649c875503460f9493f6ce/html5/thumbnails/18.jpg)
The Integrated Resource Plan : Hypothesis
GDP growth on average 4,6 % per year over the next 20 years
It requires from 30 439 MW to 52 724 MW of new capacity depending on scenarios for 454 357GWh produced in 2030.
It assumes at least 3420 MW of demand side management programmes
![Page 19: The Energy Integration in Southern Africa Jean-Pierre Favennec IFP Professor – Consultant Johannesburg – December 2, 2010](https://reader030.vdocuments.site/reader030/viewer/2022032701/56649c875503460f9493f6ce/html5/thumbnails/19.jpg)
5 models studied to establish the balanced revised scenario
A base case which minimise directs costs 3 emissions limits based scenarios
EM 1.0 : imposes an annual emission limit of 275 MT EM 2.0 : imposes an emission limit of 275 MT of carbon dioxide by 2025 but
allows emissions to go to higher levels prior to 2025 EM 3.0 : imposes a tighter emission limit of 220MT of carbon dioxide from 2020
A Carbon Tax based scenario (CT 0.0) : imposes carbon taxes escalated to 2010 Rands an contained in the LTMS documents
2 others model were studied : a regional developement model and an enhanced DSM model

The Integrated Resource Plan : Challenges A huge amount of renewables capacity
Wind : 4 500 MW in the Balanced scenario up to 2019 Solar : 400 MW Wind + Solar : 7 200 MW between 2019 and 2030
Questions raised : Is it possible to build such capacities : resources, technical
problems Problem of cost and economic rentability? Ability for quick construction and maintenance? Problem of grid stability?

The Integrated Resource Plan : Challenges (2)
Decentralised electricity not adressed
Importance of transmission lines
![Page 23: The Energy Integration in Southern Africa Jean-Pierre Favennec IFP Professor – Consultant Johannesburg – December 2, 2010](https://reader030.vdocuments.site/reader030/viewer/2022032701/56649c875503460f9493f6ce/html5/thumbnails/23.jpg)
Integration benefits Benefits : foster the development of the economy. Keys actions :
Develop infrastructures Most important partners :
Mozambique. There is already an important hydro production (Caora Bassa) and new capacities will be built. Mozambique is also supplying natural gas to RSA (Sasol)
Zambia (hydro potential) Zimbabwe
Limited cooperation : RDC. RSA is interested in electricity of Inga. But the Chinese
presence (exchange of raw materials against investments) makes difficult this cooperation.
Angola Key issue : transmission

Euratom (1957)
Euratom (European Atomic Energy Community) Success :
Legal framework, safety standard uniformisation Progressive enlargement of the cooperation Broad development on innovative technology Decrease in energy dependance Efficient information centralisation about nuclear stocks and flows,
and investment Fight against nuclear proliferation
Lacks : Some legislative contents (about normalisation for example) Decision process
![Page 25: The Energy Integration in Southern Africa Jean-Pierre Favennec IFP Professor – Consultant Johannesburg – December 2, 2010](https://reader030.vdocuments.site/reader030/viewer/2022032701/56649c875503460f9493f6ce/html5/thumbnails/25.jpg)
ECSC (1951)
European Coal and Steel Community Success :
Long term vision and comon process• Peace, stability, prosperity, solidarity• Efficient response during crisis
Autonomous legal framework• Uniform social protection and labour law
Lacks : Emergence of great enterprises Difficulty for struggling on price non-accordance and for assuring
transparancy No equalization in salary

Benefits of integration
In West Africa cost of kwh supposed to be reduced by 50 % if good interconnections between the different countries of WAPP (West African Power Pool)
