5. IRP Update
Inputs from the public and the consideration of all the comments necessitated the updating of planning assumptions, including updated information from Eskom. Modelling work, simulation and analysis of a further set of test cases was completed on the basis of this updated input data. The test cases were developed to assess the following:
|•||impact of the changed assumptions on the draft 2018 recommended plan,|
|•||the impact of plants shutting down in case of non-compliance with minimum emissions standards (MES),|
|•||the impact of Koeberg plant shutting down in 2024 if its design life is not extended,|
|•||the impact of the removal of the policy adjustments adopted in draft IRP 2018, and|
|•||realistic assumptions for gas to power capacity by year 2030.|
The details of input parameters for respective test cases are contained in Table 4.
