  1. IRP approach and potential improvements2012 Modelling colloquium31 July 2012 here

  2. IRP approach - Uncertainty • Inherently planning has to deal with uncertainty on a number of fronts: • Cost assumptions for generic options • Moving from generic options to realisable projects (local issues) • Expectations of: • Future demand • Fuel prices • Resource availability • Implementation constraints

  3. IRP approach – Variable generation Variable generation has an impact on the security of supply of the electricity system, specifically the predictability and stability of supply. Alternative back-up generation or storage may be required with significant penetration of variable technologies.

  4. IRP approach – Distributed generation The interaction of generation and transmission expansion… Considering cost of network expansion against new generation options, especially in currently unconnected areas

  5. IRP approach – DSM and Energy efficiency Designed interventions in demand-side management could provide benefits in displacing future generation as well as carbon abatement potential. Certain DSM could be related to load-shifting (options available to a utility or system operator) or energy efficiency.

  6. IRP approach – Long term • The period of study has an impact on the issues that can be dealt with under IRP • Vision of the longer term hampered by too short a window • Practicality and application of the study hampered by too long a window
