Annexure A

General Information & RFP Requirements

1. Background to Transnet and Transnet Engineering

Transnet, a state owned entity, is the largest and most crucial part of the freight logistics chain

that delivers goods to each and every South African. Every day Transnet delivers thousands

of tons of goods around South Africa, through its pipelines and both to and from its ports. It

moves that cargo on to ships for export while it unloads goods from overseas.

Transnet’s vision and mission is to be a focused freight transport company, delivering

integrated, efficient, safe, reliable and cost-effective services to promote economic growth in

South Africa. Transnet aims to achieve this goal by increasing its market share, improving

productivity and profitability and by providing appropriate capacity to its customers ahead of

demand.

Transnet is fully owned by the South African government but operates as a corporate entity

aimed at both supporting and contributing to the country’s freight logistics network. It aims at

developing South African industry, reducing the cost of doing business, while at the same time

operating efficiently and profitably.

Transnet owns a fleet of more than 2,200 locomotives and 72,000 wagons. Railway lines in

South Africa have a cumulative distance of 20,953 km, of which 8,437 km are electrified to

either 3kV DC, 25 kV AC, or 50kV AC.

Transnet Engineering, the issuer of this RFP, is a division of Transnet focusing on

maintenance and manufacturing of rolling stock and rail related products. It also focusses on

the development and integration of custom products into Transnet operations and rolling stock.

Recently, Transnet Engineering has opened a Research and Development Department for

the purpose of introducing new and revolutionary technology to the rail industry in the South

African and African markets. Transnet Engineering is the engineering backbone of Transnet

and serves the purpose of supplying Transnet with sound technical information for strategic

decision making.

2. Introduction to RFP

Energy security and increasing electricity cost pose a high risk to business. As such, strategic

energy initiatives and smart energy control are some methods of ensuring savings within this

domain without having to rely on the local electrical utility for support.

Energy solutions can be implemented within a number of spaces in the rail environment, such

as: on-board, wayside and facility spaces. Accordingly, Transnet is dedicated to continuous

development of competency in the energy solutions and application space.
