Transmission Ten-Year Development Plan 2011-2020 - Eskom

iii
The projects that are covered in this document include,
inter alia, generation integration projects required to
ensure that the network is adequate to evacuate and
dispatch power from the source to the load centres.
The publication also includes the transmission network
strengthening plans required to carry the power from
the new power stations, and reliability projects required
to ensure that the reliability and adequacy of the
transmission network are sustained as load demand
increases on the network.
The estimated rand value of the planned projects
is approximately R166 billion in the next ten years,
of which approximately R 6 billion is for customer
-related projects; R31 billion for generation integration
projects, and approximately R129 billion is related to
reliability projects. The costs given in the document
are, in general, high-level estimates and can change
as global economic conditions change; that is, costs
are sensitive to foreign exchange, commodity price
fluctuations, and global demand.
In general, the impact of reliability projects on the
customers is to improve availability of supply under
normal and contingency operating conditions,
whereas customer and generation integration projects
allow generating plant and the load to be optimally
connected to the network.
Transmission Ten-Year Plan 2011-2020
Eskom Transmission also undertakes capital
expenditure in respect of refurbishment of ageing
infrastructure, facilities, production equipment, and
strategic capital spares.
Facilities consist of buildings located at sites other
than substations that are used by Transmission for
offices, operation and control of the system, or as
maintenance depots and workshops.
Production equipment consists of office furniture and
equipment, computer hardware and software, tools
and other equipment used by maintenance personnel,
and vehicles.
Strategic capital spares are items not available
from suppliers ex stock; for example, large power
transformers, circuit breakers, etc. that are kept as a
strategic stock to allow units that fail in service and
cannot be repaired on site to be replaced as soon as
practicable, thereby minimising the risk of customers
experiencing a lengthy outage.
Projects dealing with refurbishment of ageing
infrastructure, facilities, production equipment, and
strategic capital spares are not included in greater
detail in this document, but a summary of their
costs is illustrated in the chapter dealing with capital
expenditure.
