e live in a South Africa rich with possibilities. As a state-owned company, Eskom Rotek Industries has the interests of all South Africans at heart. When Rotek Engineering and Roshcon officially merged to become Rotek in 2015, we undertook to have not just one name, but also one brand, one operating model and one culture – synonymous with the democratic South Africa in which we live today. This can be filtered down to our business ethos, in which all our operations are underpinned by Zero Harm, Integrity, Sinobuntu, Innovation, and being Customer Centric. Today, Rotek comprises the following operating divisions: Bulk Material Services, Construction Services, Logistics Services, Turbo Gen Services, and Transformer and Switchgear Services. And it doesn’t end there. A dedicated unit within Rotek’s Bulk Material Services specialises in the selling of coal combustible products such as ash, gypsum and salts. Rotek manages and sells ash from eight South African coalfired power stations – all while complying with legislative requirements. Over 2.4 million m3 of fly ash concrete was supplied for construction of the mighty Katse Dam in Lesotho. Standing 185 m high and with a double-curvature arch, it was the highest dam in Africa for over a decade. Too often, municipalities, government departments and state-owned companies enter the media spotlight for all the wrong reasons. At Rotek, we would much rather focus on the positive contributions that we are making towards building our country and uplifting the nation – having achieved remarkable success stories in the communities in which we operate.
Making a difference We have gone deep into the heart of rural communities to turn on the lights in households where this was not previously possible. By 2017, Rotek’s Construction Services had electrified five rural communities in the Eastern Cape, providing connections to 1 800 households in dire need of this basic service. We constructed the electrification backbone infrastructure that included medium-voltage lines, low-voltage lines, transformer installations and house connections. As a result, socio-economic development increased in these communities, which increased the realisation of the ideal of long-term sustainability. Thanks to our various business units, Rotek’s services don’t stop with electrification. We have been managing the reliable water transfer from the Komati Water Scheme for decades, and we also repaired 122 000 m2 of potholes in our country in just one year. Furthermore, we are currently managing one of the largest road supply chains in South Africa – a success story made possible by the passionate and dedicated teams within our Logistics Services division.
Expansion outside of SA But Rotek’s capabilities are not only limited to South Africa., as we strive to reach beyond our country’s borders. Over the decade, Botswana, Namibia, South Africa, Zambia, Zimbabwe and recently Tanzania have had to resort to load-shedding as a stop-gap measure in order to conserve energy. South Africa, SADC’s economic powerhouse, was particularly badly hit by energy shortages back in 2008 with its mining industry, the mainstay of its economy, temporarily shutting down operations in January that year to allow for the power supply situation to be stabilised. Mining accounts for about 15% of South Africa’s electricity demand. Massive investment in generation, transmission and distribution infrastructure will be required to sustain the projected increase in power demand in the region. The SADC region is estimated to require between US$93 billion and US$212 billion on short- and long-term projects to boost power supplies between 2015 and 2027. Rotek is part of the journey in the SADC region has done extensive work into Africa. We even played a role in the iconic Burj Khalifa in Dubai when Rotek transported the gigantic 828 m high steel structure for this hotel and produced the fly ash mixed in the 45 000 m3 concrete foundation. In Uganda, we are leading the way in the generation of reliable and affordable power for the country’s National Development Plan. Our market share in terms of generating electricity into Uganda’s national grid now stands at 40%, currently making us the cheapest generator of electricity in that country at US$0.01 per unit. Further to this, Eskom embarked on corporate social responsibility (CSR) projects within Uganda. The rehabilitation of Njeru Primary School is a fine example, which included the replacement of asbestos roofing, and fencing of the school. Another sterling CSR project saw Eskom partnering with Jinja West Member of Parliament Hon. Grace Moses Balyeku to construct and equip a maternity ward at Kimaka Health Centre II to the tune of USh200 million (approx. R687 000). On the skills transfer front, graduate trainees in Uganda have been given an opportunity by Eskom to gain hands-on experience in hydro generation. Eskom continues to offer industrial training to students every year and has a current intake of graduate trainees at any given time in the graduate training programme, which runs for 18 months. These are just some of the many success stories and capabilities within Rotek that go untold. Through this publication, we aim to give you insight into our business, the way we operate, and our varied abilities of which we are extremely proud. Welcome to the world of Eskom Rotek Industries.

years
of local manufacture and innovation As a truly local company, Allbro has been at the forefront of addressing some of the unique challenges associated with South Africa’s electrification.
C
onnecting more than 12 million homes to the grid across what is often a very challenging landscape resulted in the creation of solutions that are unique and, in some cases, world firsts. The additional challenge associated with many of the regions having harsh climates contributed to the development of robust and durable solutions that are different than those typically found in Europe, from where our local standards originate. Split metering and prepaid electricity were local innovations in need of housings that would address all the challenges already mentioned, while also being cost-effective.
Watch here:
Allbro is the largest producer of ready boards and weatherproof pole top boxes in the world.
A new ready board The latest innovation, which is also a world first, is a new generation of expandable ready board. Although effective, the extremely basic single electricity point that has been the standard over the last 20 years does not allow for expansion into multiple rooms. The new-generation ready board has a port that allows for a ‘room extender’ to be safely and simply deployed in a chain, for up to four rooms – with a light and two sockets available in each. The room extender can be provided by the utility, or can be purchased in an after market scenario by the consumer and can be easily fitted as a sort of appliance.
A near-indestructible enclosure Another innovation that has garnered tremendous attention since its release at Africa Utility Week earlier this year is AllVault. As the value and complexity of equipment being deployed across vast geographical areas have increased, so has the need to protect the function of these networks and devices. Lost revenue due to the bypassing of meters amounts to vast sums of money that dwarf the cost of the physical infrastructure.
AllVault’s vault-like high-security box can withstand very high levels of abuse. www.youtube.com/watch?v=zk35crHMKek
Enter the AllVault, which is designed to withstand high degrees of abuse. The unique composite material used in its fabrication was developed locally for manhole systems and is able to absorb the impact of hammers, chisels and axes, among other things. Also, intelligent locking systems allow the utility to monitor the behaviour of the technicians maintaining the network, further improving the integrity of the network and the security of the revenue.
About Allbro Allbro employs over 800 people and has factory space of close to 20 000 m2. Competencies include: • Raw material compounding – 3 900 t of raw material produced annually. • Design and development – Products are designed by an in-house team of mechanical engineers using the latest design tools. • Toolmaking – Moulds are made on-site (some as large as 8 t). • Manufacturing – Performed according to ISO 9001 global quality standards. • Testing – Laboratory on-site to verify ongoing compliance. With more than 100 million enclosures in service – some for as long as 40 years – Allbro has learned much from the real-world environment in which its products are expected to perform.

order to meet or surpass demand. Other than Mozambique and the Democratic Republic of Congo, most of the countries have a supply deficit that they are struggling to manage – giving investors a great opportunity for investing their money into power generation and transmission projects in the SADC region. The energy sector has been particularly critical to the economies of Nigeria and Angola, both of which have become major oil exporters over the past decade, as is stated in PriceWaterhouseCoopers’ ‘Africa Gearing Up’ report. The report further states that oil and particularly natural gas are also important to Egypt, but energy exports look likely to shift a bit in the coming years. Angola and Nigeria will, to a different extent, need to cope with decreasing demand from the US, where the shale gas boom has started to impact oil imports.
e l i f o rStrategy P | smetsy retnI | SROTEK
While the US is Nigeria’s main trading partner, Angola’s oil exports have been directed to China rather than America in recent years. New players may also emerge in East Africa. The International Monetary Fund (IMF) believes that Kenya will begin producing commercial quantities of oil in six to seven years. One must not forget that Tanzania has natural gas reserves, too, and Mozambique has massive reserves of both coal and natural gas. Accessing Mozambique’s coal can prove to be challenging, but thankfully South Africa is not faced with the problem of access to coal.
Energy resources Given the dominance of South Africa in terms of power generation – accounting for almost 76% of the overall generation capacity in mainland SADC – coal is the most dominant source of electricity in the region. More than two-thirds of all the electricity produced in the region comes from coal-fired plants. At least 86% of South Africa’s total generation capacity of 44 170 MW (March 2016) came from coal-fired plants, while
82% and 63% of electricity was produced from coal in Botswana and Zimbabwe, respectively. Hydropower is the sole source of electricity generation in four Southern African Power Plan (SAPP) member countries – the Democratic Republic of Congo, Lesotho, Malawi and Zambia – while hydropower also accounts for a sizeable proportion of capacity in Angola, Mozambique, Namibia, Swaziland and Tanzania. South Africa is the only SADC Member State that has a nuclear power station, owned and controlled by Eskom. The Koeberg Nuclear Power Station in the Western Cape is, in fact, the only nuclear power station in Africa. It contains two uranium pressurised water reactors, and supplies power to the national grid so that over-capacity can be redistributed to the rest of the country on a needs basis. The power station has generation capacity of 1 800 MW and has two large turbine generators, each producing 900 MW. With the exception of South Africa, capacity constraints have also seen most SADC Member States failing to

For instance, solar thermal-electric systems have the long-term potential to provide a significant fraction of SADC’s electricity and energy needs. Research has shown that most countries in southern Africa receive more than 2 500 hours of sunshine per year. Knowledge on solar energy technology is widespread in the SADC region but its use is still limited partly due to the prohibitive

initial set-up costs involved coupled with capacity constraints.
Trading electricity Construction of a new power transmission line linking Mozambique and Zimbabwe is on the cards and is expected to improve connectivity and electricity trading in the region. Commonly referred to as the MOZA Transmission Project, the venture involves the three countries that are linked to the regional grid. The three utilities in each country have since entered into a memorandum of understanding to develop an interconnector and have formed three joint project development teams – a steering committee, technical committee and commercial committee – all of which have been tasked with spearheading the implementation process being coordinated by SAPP. As part of the MOZA project, there is a need for various separate developments in each of the countries involved to complement the project and ensure that the MOZA interconnector is a success. Once completed, the interconnectors are expected to promote regional electricity trade and enhance security of electricity supply. Even better, the interconnectors will decongest existing transmission corridors and offer another wheeling path that will fully integrate all mainland SADC countries to the regional power grid. Just as the SADC region has set out to explore alternate avenues for electricity generation and supply, one of Rotek’s main strategies is to explore new revenue streams, drive

cost containment and align itself with strategic partnerships. As a performance driven contractor, Rotek is especially proud of its cidb 9 grading. A grade denotes the maximum value of a contract the contractor is deemed capable of performing within a particular class of works, with grade 9 having an unlimited tender value range. It also allows the organisation to afford opportunities to SMMEs. Coal is the most dominant source of electricity in South Africa and accounts for almost 76% of the overall generation capacity in mainland SADC
2020 It is estimated that if SADC implements its short-, medium- and long-term generation projects, the region could meet its medium-term energy demand by 2020
Capitalising on logistics South Africa stands out, ranking number one in Africa and 23rd in the world in logistics performance, according to the ’Africa Gearing Up‘ report. Egypt scores well too, coming in at number 57 worldwide, while the Democratic Republic of Congo scores among the worst of all nations, ranking 143rd. These differences in infrastructure and logistics performance translate into real costs for supply chains. According to the World Bank, it takes just 12 days to export a container from Egypt, at a cost of US$625. The journey lasts four times as long – over a month and a half – to export a container from Angola, at nearly triple the cost. And it can get even trickier if you need to cross borders within Africa. In contrast, at the world’s largest ports in Hong Kong and Singapore, it takes just five days to export a container at a cost of US$575 and US$456 respectively. If you were to transport that same container from landlocked Botswana, rail would be the best and most cost-effective option. Rotek’s Logistics Services division has great opportunities with its transportation offering spanning diverse sectors. The division is identifying key segments for its growth strategy – each one to be explored further. It is important to note that all Rotek’s strategies, regardless of the business unit, are underpinned by its six key values, namely: Zero Harm, Integrity, Sinobuntu, Innovation, Customer Satisfaction and Excellence. Rotek is committed to the highest standard of ethical conduct in all its actions and decisions.

Through meticulous planning and close monitoring, CPGP ensures that its work is executed safely and to the highest standards The variety of factors that come into play in the design of scaffolding make for quite a complex equation. Everything from required platform workloads, equipment type and tie-in points, specialised design and environmental aspects must be taken into account. So, in order to ensure that the scaffolding it assembles is safe and fit for purpose, the company has developed its own scaffolding design software in line with South African National Standard specifications. This software calculates safe working loads for the scaffolding, ensuring a structurally sound design. After design, CPGP’s expert scaffold team members collaborate with health, safety and environment officers to compile the
appropriate documentation and hand over a scaffold structure in which both the client and CPGP can have the utmost confidence.
equipment, which eliminates the chances of human error creeping in and results in the fabrication of precise, cost-effective products.

Servicing the demand for maintenance in the energy sector
S
outhern Africa faces many daunting developmental challenges. Although rich in natural resources, industrial and commercial development remains slow, poverty remains high, and access to clean affordable energy for households is nowhere near where it should be. In 2010, at the peak of South Africa’s infrastructure development and as the continent braced itself to host the largest football spectacle in the world, it was estimated that only 24.7% of households in the Southern Africa region had access to electricity, while biomass remained the primary energy source in many of these countries at the time. If we look specifically at the Southern African Development Community (SADC) countries, energy resources and supply and demand within this region varies greatly. While most Member States of SADC have abundant energy resources, they sometimes lack the technical capacity to put them to use, which is the reason for the variation in energy production and consumption. The extensive energy resources in the region are used within SADC as well as exported from the region. Energy is also traded between states: for instance, South Africa imports and exports electricity to and from neighbouring states, and also imports natural gas from Mozambique.
The Southern African Power Pool noted the need to reduce support and maintenance costs for its future trading platform. Rotek prides itself on both its on-site and workshop maintenance services.
Infrastructure development According to the ‘SADC Energy Monitor 2016’ report, energy infrastructure development in the region has been guided by instruments that include the Regional Indicative Strategic Development Plan (RISDP) – first adopted in 2003 and revised in 2015; the SADC Protocol on Energy; the Energy Cooperation Policy and Strategy of 1996 and the SADC Energy Action Plan (1997), among others. Energy is a critical area of Priority B of the Revised RISDP 2015 – 2020, which focuses on provision and improvement of infrastructure support and maintenance for regional integration and industrialisation. Considerable preparatory work has been undertaken in this area to develop enabling policies, systems and processes such as the Regional Energy Access Strategy and Action Plan of 2010 in support of the SADC

Industrialisation Strategy and Roadmap 2015 – 2063. It is expected that the environment created will help to attract private sector investment and further promote public-private partnerships.
Power pool The Inter-Governmental Memorandum of Understanding (IGMOU) of 1995 was reviewed in 2006 by SADC Energy Ministers in order to allow Independent Power Producers (IPPs) to be members of the Southern African Power Pool (SAPP), with Eskom being one of these member utilities. SAPP was created with
One of SA’s leading manufacturers of steel structures:
the primary aim of providing reliable and economical electricity supply to the consumers of each of the SAPP members, consistent with the reasonable utilisation of natural resources and effects on the environment. SAPP has identified a number of priority energy projects for commissioning over the next few years to address energy shortages in the region. Between 2015 and 2019, SAPP plans to commission a total of 23 585 MW. If this is achieved, SADC will finally be able to meet most of its power needs after several years of shortages. Despite its limited role and functions, SAPP is regarded as the most advanced power pool on the African continent. SAPP was the first formal international power pool outside of North America and Europe. It was also the first power pool in Africa to establish a competitive power market that allows countries connected to the regional grid to trade surpluses. In its business plan of 2013 on the competitive market, SAPP noted the need to reduce support and maintenance

while at the same time giving SAPP the option to add other trading products that will assist in increasing liquidity within the competitive market. Rotek’s reliable and rugged components of the primary equipment for transformer and switchgear services are often in use for decades at a time, answering to the need to keep maintenance and support costs low.
Transformer services Rotek’s on-site transformer services range from loading and off-loading, transporting, installation and commissioning, and treatment of oil with mobile oil plants, to performing various transformer tests together with technical assessments that determine the condition and general health of the transformer. Testing, servicing, repairs and replacement is performed in the field on tap-changers, bushings, and auxiliary equipment by trained and experienced site teams. These services are provided anywhere in sub-Saharan Africa on a routine basis, or after faulting has occurred on the transformer. Clients include power stations, transmission and distribution substations, industrial installations for power utilities and the private sector. In cases where un-tanking of the active part is required, the transformer is taken to Rotek’s workshop in Rosherville, which offers all the necessary facilities for bushing, tap-changer and winding services, as well as un-tanking, dismantling, inspection, testing, repair or overhaul, modification, assembly, drying, and painting – all under one roof and all done professionally and efficiently.
Switchgear services Switchgear maintenance is one of T&SS’s core competencies, and the division is able to work on all types of circuit-breakers, disconnectors and isolators, both AC and DC equipment, of voltages from 11 kV to 765 kV. Switchgear services include installation and removal,
routine maintenance according to OEM specifications, as well as refurbishment and repairs on-site. Service accreditations include Delle, Alstom and ABB generator breakers, as well as installation and maintenance of GIS switchgear. T&SS also services, repairs and tests all types of compressor plants related to air-break type switchgears. Just as in the case of transformer services, for extensive repairs or modifications, equipment is decommissioned and taken to the workshop in Rosherville, where it is refurbished under required clean conditions, with specialised equipment and testing facilities at hand. Specialised teams perform the work and these services are delivered anywhere in sub-Saharan Africa.
Engineering services Furthermore, T&SS offers transformer and switchgear engineering services that will perform investigations into plant failure or poor performance, and advises on repair strategies and cost versus benefit analyses. Independent design reviews are regularly carried out and equipment redesigned and modified for uprated capacity. Engineering services include: Service engineering, such as scope development and risk analysis

Dear Eskom and Sulzer Partners Eskom/Sulzer Partnering 2017 MESSAGE FROM ESKOM’S CORPORATE - SPECIALIST PUMP TECHNOLOGY The Eskom/Sulzer Partnering Agreement Contract has reached the mature age of 25 Years. Much has been achieved during this time. The number of Critical Pumps (Steam Feed Pumps, Electric Feed Pumps, and Condensate Extraction Pumps) that are included in the Partnering Agreement Contract has increased from 124 pumps in 1993 to 365 pumps by 2017 – a 295% increase. The increased scope has resulted in Sulzer having to double the team supporting the Critical Pumps at the 14 Eskom Power Stations included in the Partnering Agreement Contract.
09
The availability of the Pumps (SFP’s, EFP’s and CEP’s) included in the Scope of Work as per the Sulzer Partnering Agreement Contract decreased from an initial value of 34.61 hours lost per pump in 1994 to a low value of 1.14 hours lost per pump in 2017. With the average hours lost per pump per year of 1.41 hours, the average availability exceeds 99.999%. This is the availability for the plant and the components included in Sulzer’s scope of work only. This is truly a significant achievement in spite of the increase in responsibility, number of pumps and auxiliary equipment included in the Partnering Agreement Contract. This resulted in a significant improvement in Critical Pump availability and reliability which contributed positively to the low UCLF attributable to the Boiler Feed Pumps, Condensate Extraction Pumps and overall performance of the various Power Stations. This performance is a reflection of the commitment from both companies which has developed in this much valued mutually beneficial business relationship.
11
One of the challenges is the steady increase of the ageing of the Critical Pumps that are included in the Contract and we will soon be faced with some new technical challenges in the upcoming years. The latter will be as a result of the majority of the Critical Pumps which have accumulated high running hours, and as such, require increased attention. The long term health of the plant and equipment must be retained to ensure a high level of performance, i.e. reliability and availability. The condition of the plant needs to be assessed continuously to ensure that both Eskom and Sulzer plan ahead to either repair/replace and or refurbish the pumps and the auxiliary plant components as required. This will ensure that neither Eskom nor Sulzer are at risk due to surprise component failures that have a limited life. The pump drivers (electric motors and turbines) of these Critical Pumps will also need the required attention in the upcoming years. Since the inception of the contract, in 1993, the relationship between Eskom and Sulzer has grown from strength to strength. These amazing results could not have been achieved without the co-operation, maturity and dedication of the team members and support from Senior Management at both organisations.

ajor issues surrounding OEMs in South Africa relate to questions around reliability and stability of products, but it is key to note that locally manufactured products and brands can be just as good, if not better than its international counterparts. The last 10 years have witnessed increased industry consolidation through mergers, acquisitions and alliances. This trend towards global integration has been propelled by ever lower trade barriers, the increasing dominance of regional trade blocks, as well as the increasingly global strategies of major international companies that dominate the industry. The global manufacturing industry is comprised of three broad market segments: OEMs, Original Equipment Suppliers (OES), and the independent aftermarket. Locally-based OEMs have developed a healthy relationship with a young, energetic workforce and have equally strong relationships with suppliers and service providers – formulating the right mix of local and imported parts. OEMs enable mechanisms to assist industry to improve their competitiveness, productivity and quality management systems and in doing so optimise its operations and procedures to ensure South African industry integration into global supply chains. This is likely to see a strong focus on industry transformation as Rotek aims to increase local content in the manufacturing of its products while boosting skills development within South Africa. Turbo Gen Services (TGS), a division of Rotek, is a major turbine generator maintenance service provider. This division is uniquely positioned within the organisation because of its capability to refurbish large power generation turbines, generators and related equipment, with a special focus on the maintenance engineering of the turbine and the generator island. Due to the strategic importance of maintenance during electricity generation, Rotek’s TGS division has embarked on an aggressive strategy to contribute to the future maintenance and skills development needs of its shareholder. A significant number of local graduates and engineers in training, as well as artisans are being mentored and coached to ensure transferring of skills and technical knowledge. Through strategic partnerships with OEMs, facilities are being built to ensure access to specialised skills, as well as the training and development of employees. The Generator Training Centre, built in conjunction with one of the world’s leading OEMs, focuses on transformer, boiler, turbine and generator training, which allows the training of local staff in the maintenance and refurbishment of a variety of power generation equipment. On completion, it will be equipped to simulate real working conditions on a generator stator and rotor. This will enable trainees to safely and competently perform similar tasks as they will be required and expected to do when they perform generator related maintenance work at power stations or in the generator services workshop.

he outlook for South Africa’s construction industry over the next four years will be moderate, compared to the industry’s performance between 2012 and 2016, says data analysis company Timetric. Contributing to this is poor investor sentiment as a result of slow economic growth, and the embattled rand, which both impact construction spending. However, infrastructure investment in the transport and logistics, energy, and low-cost housing sectors are expected to create growth in the industry over the next four years (2017 – 2021). These projects will be underpinned by the ever-increasing need for housing as urbanisation rates continue to rise. In a report by Statistics South Africa on human settlement growth rates, the number of building plans passed grew by 6% in nominal terms in the last financial year.
Generation & transportation • 20x bulk earthworks teams • 10x concrete teams • 4x road teams

This shows an increase from R101.4 billion in 2015 to R107.5 billion in 2016. The total value of completed buildings grew by 8.3% in nominal terms. This showed an increase from R56.7 billion in 2015 to R61.4 billion in 2016.
Investing in infrastructure In its 2017 budget, the South African government has plans to invest R947.2 billion in public sector infrastructure as part of its medium-term strategic framework. Housing will receive priority as will transport infrastructure, with roads being prioritised at the forefront, will also see considerable government investment in order to improve the mobility of citizens, freight and logistics.
Looking ahead According to Timetric, the local construction industry’s growth will be driven by government plans to increase the share of renewable energy in terms of total installed electricity capacity and encourage investment in renewable energy infrastructure. Based on the Integrated Resource Plan (IRP), government plans to increase the share of renewable energy in total installed electricity capacity from 16.2% in 2016 to 22.3% in 2020.

ven though the world is seeking greener energy solutions, coal continues to dominate in South Africa. Approximately 92% of coal consumed in Africa is produced in South Africa, with the country producing in excess of 225 million tonnes per year. In 2012, Eskom dominated the domestic steam coal market in South Africa, accounting for about 116 million tonnes. Even though the utility aspires to reduce its dependence on coal fired technology from 90% to about 65%, it will remain the country’s largest buyer of domestic coal for a long time to come. As such, Eskom announced its R9.79 billion investment in rail infrastructure, which would see 140 km of new rail being built in Mpumalanga. A large percentage of the coal produced in South Africa can be found in Mpumalanga. In fact, when Witbank
In South Africa, coal dominates the energy sector, and the efficient movement of this commodity from mines to power stations is essential in ensuring that government is able to keep the lights on.

While conveyor carried coal is ideal, it would not be possible for these massive tonnage amounts, and the next best option is rail, which is cheaper, sustainable and eliminates road hazards. At the time, Eskom had been moving some 30 million or so tonnes of coal a year to its power stations by road and in 2008 it translated to 5 100 truckloads a day – the distance covered was equivalent to driving around the world 15 times daily. In 2015, Zimbabwe and Botswana agreed to cooperate in the transportation of coal, under which Gaborone will export about 10 million tonnes of the commodity per annum, using Harare’s underutilised railway system. Landlocked Botswana is continuously exploring alternative routes to export its abundant coal. It often finds it expensive to ferry its exports through the sea and is compelled to use ports in neighbouring countries.

component of the organisation’s structure. BMS offers a complete coal logistics solution, namely, the transportation of coal – by road, rail or conveyor belt – from mines to the power station stockyard. This includes vehicle registration management for Free Carrier Arrangement (FCA) transporters contracted to Eskom, monthly planning of vehicle allocations for FCA transporters, and information analysis to improve logistical operations. The division also manages, operates and maintains the conveyor systems on these sites and runs one of the largest road-based coal supply chains in the world. Particularly important to the division is public and driver safety, which is why BMS is actively involved in road safety monitoring, FCA vehicle inspections, tarpaulin management, route assessment, control and enforced route adherence, as well as continuous vehicle tracking, weighing and measuring of loads to ensure legal compliance. Through coal logistics management and coal load brokering, Rotek has also created successful BEE opportunities for previously disadvantaged individuals and groups.
Bulk water handling Another important role of BMS is that of bulk water handling. Rotek’s bulk water handling capability started around 1973 when BMS
was contracted to manage the Komati Water Scheme. The R1.2 billion project launched in 2013 was designed to solve water supply problems to Eskom’s Duvha and Matla power stations in Mpumalanga. It augments the Komati Water Scheme from the Vaal Eastern subsystem in order to help Eskom overcome its water challenges. In turn, the Matla Power Station reservoir will provide water to Kusile Power Station. This process has evolved over time into a unique body of proprietary knowledge, including correct reservoir and dam levels, as well as a documented network of interlinking pipes that deliver water to power stations. The interaction of water resources of the Komati, Usutu and Vaal River systems provides a higher assurance of water supply to all Eskom’s thermal power stations and other water users in Mpumalanga. Today, BMS continues to operate and manage sewerage and water treatment plants, bulk solid and slurry systems, dry material transport systems and is able to accurately regulate the pumping process according to water demand. Key to this success is a century-long history in successful management of the delicate relationships with landowners through whose properties these pipelines run. Source: www.transportworldafrica.com

ollowing the abolishment of colonialism in the 60s and then the fall of apartheid in the 90s, the world had high hopes for both South Africa and Africa. In fact, the World Bank predicted a bright future for sub-Saharan Africa, with projected GDP growth of over 7% per year. But life got worse on the African continent and in May 2000, The Economist referred to Africa as the “hopeless continent”. Then from 2001 to 2010, six of the world’s 10 fastest-growing economies were in subSaharan Africa, partly due to the availability of natural resources. Following this growth, in March 2013, The Economist published a new report
42
Eskom Rotek Industries 2 0 1 8
on emerging Africa, this time titled ‘Africa rising’. But what does this growth mean for transportation and logistics companies if the current bullish predictions don’t turn out to be another miscalculation? The PriceWaterhouseCoopers ‘Africa Gearing Up’ report offers brilliant insights based on extensive research. The report states that economic differences between the top ranking African countries are vast. For example, while South Africa has a US$400 billion economy, the Democratic Republic of Congo (DRC) with its fourth largest population in Africa and having significant mineral resources, has an estimated GDP of less than US$18 billion. Just like its economy, Africa’s terrain also
varies widely, which impacts greatly on critical transport infrastructure. Countries such as Algeria and the DRC are faced with many challenges when it comes to building road and rail networks, and especially bridges and tunnels. Angola has just 4 km of roads per 100 km2 of land, while Ghana’s road density is more than 10 times as high. South Africa has 62 km of roads per 100 km2. Put into perspective, Ghana’s road density is similar to that of China, while South Africa comes close to that of the USA. Another positive for South Africa is that it ranks number one in Africa in terms of logistics performance and 23rd in the world, out of 155 countries. In the report, Dr Dirk Baukmann, CFO of DHL Express Sub-Saharan

Africa, says:“Express and logistics services are the engine of economic growth in Africa. Despite challenges like underdeveloped infrastructure, we extended our international Express Network to all countries in Africa. Compared to other regions, our Africa business is still small, but growing above average.” It is evident that transportation and logistics are vitally important in South Africa. Rotek’s Logistics Services (LS) include the transportation of boilers and turbines to and from power stations; transformers and switchgear from substations; poles and pylons to remote sites; and all power generation and distribution equipment across Southern Africa. Thanks to its impressive multi-axle fleet, LS is capable of moving anything from 1 kg to 500 t anywhere in South Africa. The different types of transport services are categorised by the respective weight of the load. Where permits and escorts are needed for these operations, LS provides a turnkey solution to get the load to its destination. It operates from its main yard in Rosherville, but has a wide network of depots in Johannesburg, Polokwane,

Why ash is big business
R
otek’s Bulk Material Services division specialises in the selling of coal combustible products such as ash, gypsum and salts. Cement is the key ingredient in the production of concrete, an essential building material for infrastructure development, second only to water in total volumes consumed annually. Coal combustion products, which are by-products generated from burning coal in coal-fired power plants, play an important role in concrete production. These by-products include fly ash, which can be used to replace or supplement cement in concrete, thereby making the concrete ‘stretch’ further and assisting with cost-cutting. Recycling coal combustion products in this way is beneficial to the environment. Close to 90% of the world’s cement is produced with the use of coal as the source of primary energy. It takes about 200 kg of coal to produce one tonne of cement and up to 400 kg of cement is needed to produce one cubic metre of concrete. But probably the most impressive statistic is that the world’s largest hydropower station is built from 20 million m3 of concrete, requiring a substantial 2 million tonnes of coal.
Why ash? Ash can be used as a key ingredient for various applications such as cement, tiles, plastic, paint, rubber, bricks and blocks, road construction, brake linings and mine backfilling

Eskom is home to 15 coal-fired power stations, which produce ash that is available for utilisation in different applications as long as environmental compliances are met
Eskom Rotek Industries 2 0 1 8
5 types of ash Rotek offers 5 different types of ash, available at all coal-fired power stations:
Fly ash is the bulk of Rotek’s ash produced and is the fine, powder-like dust that is collected in the electrostatic precipitators or bag filters.
Coarse ash, also known as boiler bottoms ash, drops down from the furnace and is collected in the ash hopper at the bottom of the boiler.
Clinker ash is obtained from a chain grate boiler process that was used in the older power stations.
Mixed ash is the rejected or excess unclassified fly and boiler bottoms ash co-disposed at a common ash handling facility.
Cenospheres are formed during coal combustion in thermal power stations where glassy ash particulates are generated.

In order to comply with legislative processes and to promote fairness and transparency, ash is sold on a tender basis. Rotek will gladly meet with clients to understand their intentions and expectations for the use of ash, to advise on purchase requirements, and to explore future possibilities. Topics of discussion will include: • the type and volume (tonnes) of ash required • the approximate location of the ash and period of time the volume would be needed • the intended use of the ash • if samples are required, they could be collected at the agreed location • transformation objectives with a specific focus on local content.
The mighty Katse Dam was the focal point of the first phase of the Lesotho Highlands Water Project (LHWP). Requiring over 2.4 million m3 of fly ash concrete for construction, the 185 m high, double-curvature arch dam was the highest dam in Africa for over a decade. The main objectives of the LHWP were to supplement the water supply to South Africa and to provide Lesotho with hydroelectricity. When construction started in 1991, the LHWP was the largest and most complex construction project of its type in the world.

rans-Africa Projects is uniquely and perfectly poised to serve the complex needs of the energy sector, as a result of its shareholders, leading global engineering and construction company Fluor, and Eskom – the largest utility on the African continent. The company is a 50/50 joint venture between Fluor and Eskom and was founded in 1995 on the back of the successful Cahora Basa Project, in Mozambique, to reconstruct and refurbish the high-voltage DC transmission line. The joint venture company has since grown to execute projects both nationally and internationally, and employs more than 150 people (primarily technical staff ). Its key focus is offering a full range of specialist and EPCM services in the power transmission and distribution market. The company was originally set up to do work outside of South Africa; however, in 2003, Trans-Africa Projects redirected its efforts to almost exclusively supporting Eskom with its expansion plans in South Africa. Today, Eskom accounts for the majority of work executed by Trans-Africa Projects. The company’s African and international projects have all been successfully managed from its head office in Midrand and, in the interest

of delivering a seamless regional experience, Trans-Africa Projects has established offices in Cape Town, Durban and Maputo, Mozambique.
Unparalleled intellectual property Trans-Africa Projects specialises in highvoltage transmission, sub-transmission, distribution and electrification projects, ranging from 11 kV to 765 kV. The company’s consulting and engineering, procurement and construction management expertise allows it to offer its clients comprehensive solutions that cover the full value chain from project design and management to commissioning supervision and maintenance support. According to Malambo Shakantu, managing director of Trans-Africa Projects, the company is able to offer a unique value proposition because of its association and access to both Eskom and Fluor’s intellectual property. “We have access to a worldwide network of specialists and the best intellectual property in the power transmission and distribution space, thanks to
our shareholders Fluor and Eskom. We’ve also established technology sharing agreements with international industry experts such as the State Grid Corporation of China, which has placed us at the forefront of the highvoltage industry and enables us to offer our customers a total solution,” Shakantu explains. Through its shareholder agreement with Eskom, Trans-Africa Projects has access to specialised Eskom resources. “Not many consulting firms can say they have access to this capability and we see it as an added benefit for our customers. Through it, we are able to offer our current and prospective customers costeffective design solutions that are truly unique and that we know will work,” Shakantu points out.
Partnering with customers While the technical and intellectual support of industry giants is a key differentiator for Trans-Africa Projects, its business philosophy – as it relates to its customers – is something that allows the company to really stand out from the crowd.
e l i f oProjects rP | s mets S r|e tERI nI Trans-Africa Logistics Services | yProfile
“Our client-centric business philosophy has two key aspects: first, we believe that the customer is our partner, and second, we are in the business of providing solutions. So while we might say that we offer transmission design and engineering services, we really believe in sitting down with the customer and working with them to understand their problem, so that we can find the best possible solution,” Shakantu notes. “The success of our clients is our success and some of our most notable achievements as Trans-Africa Projects have been assisting our customers to achieve outstanding cost savings,” he adds. Working in Africa, Shakantu notes that project funding and affordability are major challenges for many customers. As such, the company endeavours to find the most cost-effective way to complete a project, while ensuring it delivers. “Trans-Africa Projects has been at the forefront of delivering new transmission lines and substation solutions, and factors such as our unique tower and foundation designs and conductor selection have resulted in major cost and time savings for our clients on recent projects,” Shakantu explains. “Cost-saving comparisons for potential clients, such as a utility company in the Middle East, have demonstrated that transmission line costs and refining construction methodologies can lead to a cost saving of up to 40%. This is something we are able to achieve for our clients by partnering with them and working smartly,” he continues.
GLOBAL PRESENCE Trans-Africa Projects has completed projects in 13 countries across Africa, including Mauritius, and has delivered exceptional work for clients further afield, in countries such as: • Australia • China • India • Indonesia • Iraq • Mongolia • Papua New Guinea
Moving forward Looking ahead, Shakantu notes that Trans-Africa Projects is on a mission to maintain its position as one of the leaders in the transmission design and engineering sector, while delivering highquality solutions for its customers. “We are committed to serving our clients and providing returns to our shareholders. In order to do that, we need to continue working with our biggest client, Eskom, on projects in line with its expansion strategy, all while taking the time to nurture our company’s own expansion plans.” Shakantu says the company is looking to expand its presence to the Middle East by establishing an office in the region, as well as further up into Africa with an office in Kampala, Uganda. “We are also looking to expand our customer base by adding other clients outside of Eskom to the mix. This, we believe, will enhance our position to increase our value add to our shareholders, and touch a broader market with our unique offerings.” Shakantu says the company is also working to expand its incubation programme, which focuses on skills development within the sector. “Through the programme, we are supporting upcoming black-womanowned firms in the industry, and this is something we are really hoping to do more of going forward. “TAP continues to partner with various stakeholders in making a positive impact in communities in which it works. We believe that people are attracted to companies that provide technical complexity and have a deep caring for the environment and this is one of our cornerstones in building a platform where people can make that difference. “In a nutshell, our biggest goals for the coming years are to ensure that we deliver for our clients, for our shareholders and for our country,” Shakantu concludes.

A lesson from Africa
How Eskom Uganda is leading the way in the generation of reliable and affordable power for Uganda’s national development.
E
skom Uganda Limited (EUL) was incorporated on 22 November 2002 and was awarded a 20-year concession to operate and maintain two power stations in Uganda, namely the Nalubaale and Kiira Hydro Power Plants. EUL took over operations and maintenance of the complex from the Uganda Electricity Generation Company Limited (UEGCL) on 1 April 2003. EUL is a subsidiary company of Eskom Enterprises SOC Limited South Africa – the investment arm of Eskom Holdings SOC Limited. Over its 14 years of electricity generation in Uganda, Eskom has adopted prudent utility practices to ensure that it meets dispatch demands and generates enough electricity for the country. Eskom has assembled and developed competent staff in operations and maintenance, and has continued to excel in providing reliable and affordable electricity for national development at US$0.01 per unit.
Investments and milestones Eskom’s market share in terms of generating electricity into the national grid now stands at 40%. Eskom is currently the cheapest generator of electricity in Uganda. To date, Eskom has invested in excess of US$20 million in upgrading systems and equipment at the power plant.

Graph 1 Plant availability performance for April 2003 - 2016 • Eskom intends to invest an additional US$25 million in the remaining period of the concession for upgrades and new systems in order to sustain plant availability. • Over the last 14 years of operation, Eskom has paid USh14.3 billion in corporation tax. • Recently, Eskom procured two new interbus transformers at a cost of US$2 million. These transformers are crucial in stabilising power supply to areas from Lugazi to the greater Busoga regions of Jinja, Iganga and Kamuli, through coupling the two substations. This, in turn, will promote industrial growth in the region.

Eskom has consistently exceeded its target in terms of plant availability, which has been maintained above the power purchase agreement minimum target of 94% (see Graph 1). Eskom has made investments that have led to the efficient use of water to generate power. When Eskom took over the facility before implementation of the governor upgrade project, energy conversion efficiency was at 21.53 m3/kWh, which was quite poor. This meant that less energy was extracted from each cubic metre of water. This has since reduced to an average of 19.2 m3/kWh – meaning that more energy is extracted per cubic metre.
Creating energy efficiency awareness Drawing lessons from South Africa, Eskom has partnered with the Ugandan Ministry of Energy and Mineral Development to promote awareness by educating the public on the efficient use of energy.

ecognising shortcomings in an organisation’s culture is one of the strategic paths that leads to its success. Companies are finding it necessary to constantly evolve to keep up with technological advancements and embrace the digital age.

research to prepare the country for Industry 4.0. While it may seem a long way off for most, the use of artificial intelligence is already common in our everyday lives and automation is increasingly dominating local workshops and factories. A new McKinsey Global Institute report found that realising automation’s full potential requires people and technology to work hand in hand. It further states that recent developments in robotics, artificial intelligence, and machine
learning have placed us on the cusp of a new automation age. Robots and computers can not only perform a range of routine physical work activities better and more cheaply than humans, but they are also increasingly capable of accomplishing activities that include cognitive capabilities once considered too difficult to automate successfully, such as making tactic judgments, sensing emotion, or even driving. Automation will change the daily work activities of everyone, from miners and landscapers to commercial

bankers, fashion designers, welders, and CEOs. However, the big question remains: how soon before these automation technologies become a reality in the workplace?
Preparing for the future The FIR will influence most, if not all, economic sectors. From a technology perspective, South Africans will witness the integration of physical, digital and biological technologies. This shift is sure to cause disruption within many organisations, as workforces undergo change. It is also for this reason that many

companies are focusing on understanding the analytics of their people from the traditional information required by human resources to understanding behaviours and mindsets. Establishing and following through on strategies is also crucial in preparing for the future. Although the basic principles that make for a good strategy can sometimes be obscured, ultimately, strategy is a way of thinking and not a procedural exercise of a set of frameworks. Trained by the largest global management consultancy, the Top Consulting Group (TCG) currently
supports all divisions within Eskom. TCG’s expertise lies in organisational design; strategy development and implementation; productivity improvements; and operational optimisation while adopting a change management approach for sustainability. The group is passionate about solving complex challenges that matter to our clients, with the objective of developing a better South Africa. With a mandate to help Eskom and other state-owned enterprises in South Africa develop sustainable solutions to mission critical challenges, TCG is united and deeply committed to the organisation’s success, and offers post implementation support to previous projects, if required.

Driving supply chain successes As a market leader that has been in operation for nearly 25 years, Dovetail Business Solutions is an obvious first choice for companies seeking logistics software solutions.
D
ovetail is a niche software provider to the transport and warehousing industry, and has, since inception, been selling transport and warehouse management software (WMS and TMS) to companies in South Africa and various other African states. Its services also extend to implementation and after-sales support. It has been doing all this for the past 25 years. For a company to be in business for what is effectively a quarter of a century and continue on an upward growth trajectory, it has to be doing something right. In this case, the longevity of the business can in part be attributed to the quality of the solutions Dovetail offers.
Robust solutions and systems Shermandra Singh, commercial director at Dovetail, explains, “Our solutions are robust and fit for purpose. They have been designed to handle complex operational processes while providing an easy-to-use end user experience.” Dovetail’s focus is on providing logistics companies with end-to-end WMS and TMS solutions that will have a marked impact on operational efficiencies and fuel costs, and optimise supply chain logistics. Coupled with strong systems, the company has a wealth of supply chain IP – whether among the executive team or the
consultants who implement and support Dovetail’s solutions on the ground. The company strives to be the best in the business in Africa when it comes to logistics software solutions and makes a concerted effort to work with like-minded clients. Commenting on Dovetail’s growth path, Singh expands, “Our future growth is linked to continually increasing our South African client base while expanding the use of our solutions across Africa. We have had immense success in various African countries over the past four years and will continue to build on this.”
A mobile, automated future Effective supply chains underpin almost all modern commercial activity and the logistics industry is certainly in a strong position; however, in order to remain at the leading edge, businesses need to adapt to and drive the rapid evolution of mobile technologies and automation. One of the biggest advancements with regard to tech in Africa has been the adoption of mobile technologies. And with the increasing affordability of smartphones, Africans have greater access to the internet as well as exposure to international demands, standards and trends, including automation. Mobile technologies have made significant improvements in creating supply chain visibility and, in the logistics and transport sector, many
countries in Africa are also moving towards automation. Africa is still a number of steps away from completely automating warehouses and supply chains, yet transport, courier and warehousing companies are realising the importance of automated data processes. “They are slowly but surely starting to implement logistics software solutions that can automate information processes,” adds Singh. “With the rise of e-commerce, consumers are also increasingly using mobile technologies to buy and compare products and prices at the click of a button, further stressing the need for supply chains to become stronger, more effective and more transparent and to use mobile technologies for streamlined service delivery,” Singh asserts. Mobile technologies help delivery companies to become more streamlined while creating a more transparent delivery process for the end consumer in the form ETAs and delivery notifications. The growing expectations of modern users and businesses make it all the more necessary for companies to keep up with tech developments. As a leading niche software service provider that understands its clients and the sector, Dovetail Business Solutions is the perfect partner to logistics operations looking to move forward in this ever-changing world.
