QUESTION 2 [10]
Eskom decided to implement load-shedding nationally on a regular basis as a measure of last resort
to prevent the collapse of the power system country-wide. The schedules on ANNEXURE A are
designed around the days of the month.
Load-shedding stages depend on the extent of the shortage of generation capacity to meet the
country’s electricity demand, with stage 1 being the least serious, and stage 3B being the most
serious.
o Stage 1 allows for up to 1 000 MW of the national load to be shed
o Stage 2 allows for up to 2 000 MW of the national load to be shed
o Stage 3 allows for up to 4 000 MW of the national load to be shed
2.1
How long, in minutes, will one period of load-shedding last per area?
(2)
2.2
On which date(s) can a person staying in Langa experience loadshedding between 16:00 and 18:30 if it is Stage 1?
(2)
2.3
Provide the area numbers indicated with X on ANNEXURE A.
(2)
2.4
If there is Stage 2 load-shedding in Philippi on 5 June 2015, at which
time can the residents expect the power cut to commence?
(2)
2.5
On how many days will residents of Mitchell’s Plain not experience
any power cuts during Stage 1 load-shedding?

Jamie organisied a Treasure Hunt to raise funds. He hid a number of “treasures”, like money and
toys between the food and activity stalls. He then drew a map and indicated with an X where
these treasures might be found. He charges R2,00 per entry and all the prizes have cost him a
total of R69,80. The map below shows where the contestants can look for the treasures.
