STADIUM ELECTRICITY
SUPPLY PHILOSOPHY
Electricity Supply Philosophy for Peter
Mokaba Stadium

•
•
Pitch lighting powered by a permanent 800 kVA motor
generator set. Municipal power as standby.
Legacy stadium building systems (IT, selected lights,
fire and evacuation systems, electronic systems, sound)
supplied by municipal power (4x1500kVA 11000/400 V
transformers) and 1600 kVA permanent generator as
standby.

STADIUM ELECTRICITY
SUPPLY PHILOSOPHY
•
•
•
UPS System with 600 kVA capacity for 10 min. for start
up of back up generator (in 2 above)
Broadcast centre IT & T powered by temporary fully
redundant generator installation – 2 identical
generators, synchronized located outside the building
on trailers. Municipal power as further standby. (N-2
security of supply)
Stadium precinct overlay and domestic load supplied
from municipal grid (mini-subs) with back up generators
or from the stadium system

STADIUM ELECTRICITY
SUPPLY PHILOSOPHY
•
•
Precinct street lights and parking areas supplied from
municipal power ( 6 mini substations with temporary
500 kVA back up generator sets).
Fan fest park supplied from 2 x 500 kVA mini
substations with temporary back-up generators.

DEFINITION OF ELECTRICITY
SUPPLY ZONES
• ZONE 1: Eskom 132kV network
• ZONE 2: Polokwane 66KV network
• ZONE 3: 11kV network from Beta substation to Peter
Mokaba Stadium
• ZONE 4: All electrical infrastructure at the stadium
• ZONE 5: All other municipal 11kV and 400V electrical
infrastructure
• ZONE 6: Various diesel generators provided
5
DURING THE EVENT
OPERATION
Zone 1 (Eskom 132kV network)
• Zone 1 will be looked at by Eskom from the Regional
Control Centre, Witbank.
• The City of Polokwane electricity department’s control
room will be in telephonic contact with Eskom control.
• Eskom to monitor the feeds to Polokwane and be
responsible should there be a failure.
• Eskom will have personnel on standby at the intake
substations.
• A loss of one supply is critical as the other will be
overloaded and the supply to Polokwane is no longer a
firm one.
6
DURING THE EVENT
OPERATION
Zone 2 (Polokwane 66kV network)
• Zone 2 will be the responsibility of the electricity department.
• The status of the network will be monitored from the control room.
• During match day, there will be personnel stationed at the key
substations (Beta, Golf Club and Peter Mokaba).
• Visual checks will be done of overhead lines and switchgear on
match day and match day minus one. All battery supplies will be
checked to confirm charge.
• Routine checks will be done on all safety equipment during the event
period.
• A loss of supply in Zone 2 is a serious issue high as the supply will no
longer be firm.
7
DURING THE EVENT
OPERATION
Zone 3 (11kV network Beta to Stadium)
• Zone 3 will be the responsibility of the electricity department.
• The status of the network will be monitored from the control room.
• During match day, there will be personnel stationed at the key Golf
course substation.
• Visual checks will be done on match day and match day minus one.
All battery supplies will be checked to confirm charge.
• Routine checks will be done all safety equipment during the event
period.
• A loss of one supply in Zone 3 is medium as there are three feeds to
the stadium with N-2 redundancy.
8
DURING THE EVENT
OPERATION
Zone 4 (Electrical infrastructure at Stadium)
•
•
•
•
Zone 4 will be the responsibility of the stadium operator.
As there is no SCADA on the entire stadium network, the status of the
network will be monitored from manually at each local substation or
generator. During match day, there will be personnel stationed at each of the
identified areas and will provide feedback to the electrical leader.
Visual checks of all switchgear and UPS will be done on match day and
match day minus one. Routine checks will be done all safety equipment
during the event period.
The diesel generators will be run on match day minus one as a test. The
routine checks as per the manufacture specification will be followed. All
battery supplies will be checked to confirm charge.
• The stadium operator will be responsible for fuel management.
•
In the event of a total loss of power, the stadium is equipped with emergency
lighting to assist in the safe evacuation of people.
9
DURING THE EVENT
OPERATION
Zone 5 (All other munic 11kV and 400V networks)
• Zone 5 will be the responsibility of the electricity department. The
control will monitor the 11kV systems while the 400V will not be
monitored.
• Visual checks will be done prior to the event. All battery supplies will
be checked to confirm charge. Routine checks will be done all safety
equipment during the event period.
• The faults will be investigated only after they have been reported by
the public.
• Staff will be on 24 hour stand-by
• During match day, the VOC commander will notify the electricity
department should there be a problem at areas such as park & rides
and the like.
• Loss of supply in Zone 5 is high if the supply to the team hotels and
training areas is experienced.
10
DURING THE EVENT
OPERATION
•
•
•
•
•
Zone 6 (All generators outside stadium itself)
Zone 6 will be the responsibility of generator contractor.
The contractor will be responsible to carry out all routine
checks as per the diesel generator manufacturer’s
requirements.
The contractor will have adequate staff available during
the event period.
Further, he will monitor fuel and the changeover from the
grid to the diesel generators.
The contractor’s compliance with the OSHact will be
reviewed by the electricity department prior to and during
the installation and operating period. Routine checks will
be done all safety equipment during the event period.
• Loss of supply in Zone 6 is low as this is a back up supply.
11

LOAD SHEDDING
Eskom Northern Region and Polokwane have done
scenario planning around load shedding, if necessary.
The following principles will apply:
• No load shedding on Beta supply area (2010 event area)
• Load shedding of CBD area to be avoided
• Rural areas around city to be load shedded first
• Avoid load shedding of hotels, hospitals, airport, other
key installations
Final planning to be documented during April 2010
26
AFTER THE EVENT
• Meetings will be held between the Electricity department,
ARUP, Aggreko, Match IT&T, Stadium electrical support
personnel, HBS and all other relevant and affected
parties within 1 day after an event.
• The purpose of this meeting will be to identify any
problems encountered during the event.
• The meeting will discuss the performance of all
personnel, equipment and procedures during the event.
• Such meetings will be minuted and corrective actions will
be determined, documented and performed in order to
ensure that problems encountered during an event will
not be experienced again.
27
AFTER THE EVENT
• The largest issue that would have to be dealt with after
the event is the removal of temporary diesel generators
rented by the City and the management of the fuel
removal and spillages if any.
• Each installation will be visually inspected by a
representative of the City and a hand back signed by the
representative from the contractor to the City.
• Restore normal shifts
