4. The Coal Logistics Strategy resulted in a concerted effort to move bulk fuel transportation from road to rail Ensure that all coal logistics are done in a safe and socially responsible manner Minimise adverse environmental impact of coal transport Involve BEE participants, where possible Where possible, accelerate reduction in trucking Objectives Security of supply Cost optimisation Safety and social responsibility In order to respond to the objectives of the Coal Logistics Strategy, the Road to Rail Migration approach to move from road to rail transportation was initiated Put the appropriate and relevant logistics solutions into place to ensure that power stations are supplied with coal from the targeted sources Where possible, build in the ability to switch modes of transport/or sources of supply in the event of supply problems Ensure that the transport of coal is done in the most cost optimal manner i.e. conveyor or rail Limit road transport due to high cost, and unacceptable safety/ social impact and risk Minimise additional cost of road repairs

6. A number of initiatives initially identified have not realised resulting in a revision of the planned rail capacity from 32Mt to 23.6 Mt by 2018 32,0 13,0 3,0 5,0 FY18 2,0 32,0 13,0 5,0 6,6 2,0 2,4 3,0 FY16 31,0 13,0 5,0 6,6 2,0 2,4 2,0 FY15 30,5 13,0 5,0 6,6 2,0 2,4 1,5 FY14 8,5 6,6 FY17 2,4 29,0 13,0 5,0 6,6 2,0 2,4 FY13 18,0 5,0 2,0 FY12 12,6 0,5 2,5 1,1 2,5 Grootvlei Duvha Majuba Hendrina Tutuka Camden 19,5 10,0 3,5 2,5 FY15 15,5 9,0 2,8 3,5 7,4 FY14 11,5 8,2 2,0 1,3 1,2 FY13 10,2 0,4 1,8 FY12 8,6 0,2 3,5 FY16FY18 23,6 13,1 3,5 8,0 FY17 20,5 10,0 3,5 Insights Duvha - Initial assumption of the tied colliery (Middleburg mine (MMS)) running out of coal is no longer valid as the production of the mine has improved significantly. Duvha is now only supplied by a conveyer belt system, reducing the rail capacity by 3.0Mtpa Hendrina - Supplied by a tied colliery,Optimum, through a conveyer belt system. The same assumptions as above are also no longer valid. This has affected the planned rail capacity of 2.4Mtpa Camden – Opening of Usuthu colliery, situated 5 km from the power station, has reduced the Camden rail capacity requirement from 5 to 3.5Mtpa Due to capex constraints the following have been put on hold – Tutuka tippler (additional rail capacity of 7.5Mtpa) – Grootvlei tippler (additional rail capacity of 5Mtpa) Power station rail capacity plans, initial Million tonnes (Mt) Power station rail capacity plans, revised Million tonnes (Mt) Confirm Grootvlei numbers. Graphs show increase from 2 to 3.5

15. Summary The Coal Logistics Strategy resulted in the Road to Rail Migration approach Some recommendations have been put forward to bridge the gap  The Logistics department in PED is exploring solutions with Transnet Freight Rail (TFR) that will increase the 2018 rail capacity to 29.1Mt  These solutions include ̶ Collaboration with TFR to capitalise and manage a tippler solution at Tutuka ̶ Provision by TFR of a container solution at Grootvlei  The overall reduced burn requirements of various stations and proximity of mines to power stations decrease the viability of rail use  As such, it is unlikely that the initial target of 32Mt will be attained by 2018 The changing environment has resulted in the targets set for the Road to Rail Migration not being met  There have been a number of changes in the factors that underpinned the initial road to rail migration approach  These factors include: ̶ Some of the rail projects identified originally are not financially viable anymore due to the weak economic benefit ̶ Capex constraints have resulted in a halt to the capacity upgrade projects  Due to these factors, and if there are no changes in the status quo, the rail capacity is expected to reduce from 32Mt to 23.6Mt by 2018  The Eskom Coal Logistics Strategy was initiated in 2008 with the following objectives ̶ Security of coal supply to stations ̶ Cost optimisation of coal transportation ̶ Safety and social responsibility of coal logistics  A direct result of the strategy was the concerted effort to move bulk fuel transportation from road to rail  In light of this, Eskom committed to transporting 32Mt per annum of coal via rail by 2018¹ and this was approved by the Eskom Board in April 2009 1 Commitment is to provide rail infrastructure capacity to allow movement of 32Mt per annum. Actual increase in coal tonnages being moved by rail will be obtained through operational efficiencies, resourcing, maintenance, and continuous improvement Source: PED, Team analysis 15
