IEP scenario ver 1 by gyvwpsjkko


									Integrated Energy Planning


 The document discusses the background and sketches proposed scenarios to be tested by the model together with relevant developments in the energy field.

       2.1. The Integrated Energy Plan (1) (IEP(1))

         2.1.1.     IEP(1) was produced in 2002 in accordance with the mandate from the Energy White Paper. The main conclusions from IEP 1 were very briefly:
         2.1.2.     Energy supply will remain reliant on coal for at least the next two decades.
         2.1.3.     Diversify energy supply.
         2.1.4.     Continue investigations into nuclear options
         2.1.5.     Promote energy efficiency.
         2.1.6.     Maximise load factors on electricity generation plant to lower levelised lifecycle costs.
         2.1.7.     Lessen reliance on imported liquid fuels by exploring oil and gas deposits.
         2.1.8.     Increase existing oil refineries’ capacity when appropriate rather than greenfields developme
         2.1.9.     Continue with existing synfuel plants and supplement with natural gas as feedstock.
         2.1.10.   New electricity generation will remain mainly coal based.
         2.1.11.   Ensure environmental considerations in energy supply, transformation and end use.
         2.1.12.   Promote access to clean and affordable energy
         2.1.13.   Introduce policy, legislation and regulation for the promotion of renewable energy and energy efficiency
         2.1.14.   Undertake integrated energy planning on an ongoing basis.
Scenarios for IEP 2

Scenarios are intended to be internally consistent story lines about possible futures. A multiple scenario approach attempts to cover a wide range of possibilities.Each scenario is
created using a number of building blocks such as population projection, economic prospects, change in efficiency, shifts between the various fuels, technology innovation and
diffusion, stronger or weaker efforts to tackle environmental problems and more effective policies.

Scenarios are to consider and be linked to SA national development goals as well as energy sector, and consider the implication to the energy sector
Demand side:

Broad implications for energy demand of each macro-scenario(e.g. expansion or shrinking of various consumption)

Development path which optimally supports national development goals and sector demand side goals and resulting policies as specified in the Energy White Paper( goals around
economic growth and increasing access to energy)
Supply mixes to optimally meet the demand for services in the various sector( best energy mix for low-income household for example )

Supply side
Link to resources base changes , technology development , International trends and pressure
Security through diversification
The following are some brought ideas around which scenarios may usefully be developed
1. Promotion of renewable
2. Promotion of DSM and energy efficiency
3. Pursuing nuclear energy sector
4. Various new technology scenarios( fuel cell, coal-bed methane
5. Internalisation of various externalities costs( issue around pollution)

Modelling of energy sector

Scenarios for the energy sector which are developed will form part of the basis of the modelling. The modelling of the scenarios has a critical role in the quantification of financial
and broader economic implication of various choices around the development of the energy sector, which feed directly into policy and strategy formulation.
The modelling work is expected to involve the following:
Consider the modelability of Scenario, for example linked to data
Assess data availability for scenarios to be modelled, identify gaps
Undertake computer modelling exercise
Translate modelling output into the implication for the energy sector
