Method

1. Create load shedding historical schedule

ESP provides a history of when load shedding changed to a different stage. I found this tricky to work with as it did not enable me to easily lookup what stage the country was in at a particular point in time. It would have required doing a look up of the previous change and then figuring out which slot relates to the time and which block had load shedding in that slot

So, I created 2 hour (column ’twohour’) slots for (12 per day) everyday and expanded the ESP history so that each slot was allocated a stage. These 2 hour slots acted as a time series axis and enabled me to map the historical stages in a time series graph

2. Convert area schedules into ’two-hour’ format

Using schedules provided by Eskom, CPT, Durban and Joburg. I converted the load shedding schedule into two hour slots for the various load shedding stages. This is what then enabled me to now lookup the load shedding schedule for a particular block according to the stage it was in - using the above history
