20 YEAR MASTERPLAN
Gomsand Bulk Capacity project
2011/12
To keep as 100% back-up
configuration by adding two
35MVA transformers from
Wolmer and other two 35MVA
transformers from Orchards.
(Upgrade from 35MVA to
105MVA)
To accommodate the future
growth in the Central Region
The total project cost: R33 million

Streetlight Monitoring Devices
• To introduce a Tele-management systems for
streetlights: (Real Time Streetlight Monitor)
– To control streetlights remotely
– Proactive monitoring and maintenance of streetlights in
the Inner City
– Safety; manually control of the lighting levels for the safety
of pedestrians and motorists
– Maintenance control: in line with SANS 10 098,
maintenance plan on streetlights
– Management Cost Reduction
– Energy Cost Reduction
Social Responsibility
• Electrification of the informal settlements to
provide basic services to the low cost housing
• A total number 0f 23, 000 backlogs in the

• Creation of temporary jobs during the
implementation of projects (target: 5000 jobs
to be created)

CONCLUSION
• The present CoT electricity network is fully loaded and Eskom will
only be able to supply more capacity by February 2014.
• Most of the Infeed-stations are overloaded and some needs to be
upgraded in order to provide more capacity to the City.
• Need to explore new technologies to better our services but the
question budget still remains a big concern
• The challenge is that, even if the substations are upgraded, no
power can be transferred until CoT network has been upgraded.
•
The under funding/ Cut of funds of electricity bulk infrastructure
have a negative impact on service delivery and development and the
loss in revenue.
