4 PRIMARY ENERGY COAL COSTS

5 Eskom is navigating a dynamic coal environment with many challenges to manage Coal supply shortfall at several power stations with long term contracts coming to an end Cost of mining coal consistently increasing above inflation and export prices influence on the domestic market Competition by the export market for Eskom grade coal within the 42-55kcal range Lack of new mining investment in large scale coal mines and execution of current mining rights Flexibility in coal procurement to match older power stations production ramp down Increased pressure from local communities for localization of Eskom goods and services procurement Growing Renewable Energy sector disrupting Eskom s business model and no demand growth Investors and Funders migration away from coal technology. Signal - disinvestment in the South African coal industry by multinationals

6 Within this environment - Eskom has three primary objectives Optimal cost of coal Contribute to the lowest cost per MWh sent-out for Eskom by delivering pit to boiler optimal coal costs Security of coal supply Meet volume requirements with a safety margin above coal demand to enhance flexibility in absorbing burn variance Support transformation in coal procurement spend Eskom will continue to support transformation of its coal procurement spend in line with the Mining Charter and implemented through compliance to the Preferential Procurement Policy Framework Act and Broad-Based Black Economic Empowerment Act 5

7 6 Critical success factors for objectives to be met include The NERSA tariff determination based on market cost of mining and coal prices Availability of capital funding for investment in cost plus mines Eskom s ability to send a strong signal to procure coal on a long term basis to achieve prices projected in the application Policy and legislation certainty to stimulate investment in new coal mines

8 Cost of coal burn to generate electricity over FY2 FY22 period is projected to be R198.5bn (Rbn) 64 +1% Demand as per 11 year supply plan Insights The difference in volumes between coal purchases and coal burn in: FY17 FY18 FY19* FY2 FY21 FY22 FY19: Due to contractual volumes at Lethabo & Medupi exceeding burn requirements Building stock at individual power stations Coal burn volumes (Mt) Coal purchases volumes (Mt) FY2 FY22: Primarily due to contractual coal volumes at Lethabo & Medupi Power Stations being higher than the burn requirement * FY19 YE projection as at end Nov 218

9 Eskom needs to secure up to 1318 Mt of coal in long term, (if no Cost Plus investments are made) and 195 Mt should investments in Cost Plus mines are possible and made Secured Supply WITH Cost-plus CAPEX Mtpa Additional 223Mt secured through cost plus investments Shortfall Cost plus with investment Cost plus Medium term Fixed price Shortfall reduces from to 1 95 Mt with cost plus mine investments Secured contracts fixed and cost plus For foreseeable future Eskom is largely contracted at: Matimba - fixed price Medupi - fixed price Duvha - fixed price Lethabo (New Vaal) will require investment & extension Demand Shortfall as with per cost 11 year plus supply investments plan as per draft IRP 195Mt Eskom needs to procure coal by: Providing long term large volume RFP s to the market, to trigger long term contracts with mines and investments into coal mining Revitalising and continuing investment in cost-plus mines Managing flexibility of demand will be done through Medium term contracts. These contracts may be at market related prices, however it provides flexibility for Eskom to navigate risks involved

10 In 218, Eskom has secured 91.8Mt of additional coal to be supplied over a number of years Percentage contribution of contracted coal vs. requirement % 4% 18% 18% 26% 29% 4% Demand as per 11 year supply plan Insights Coal requirement compared to that contracted will always fluctuate depending on a number of factors including: Electricity demand and outlook. 98% 78% 76% 71% 68% Demand forecast per power station and variations to that demand on a daily, weekly, monthly and any other periodic basis. Performance of contracted coal suppliers. Realization of projected coal purchases that are not yet contracted at time of presentation Uncontracted Flexibility Pipeline Secured 9

13 SA s historic bituminous coal production = local + export sales. (No surplus availability) Sales vs Production of bituminous coal (Mt) Comments No surplus coal in system. All bituminous coal produced is either sold locally or exported. Production in 216 is almost the same as in 26, but export volume is higher This is after five years of confusion, after five years of the mining moratorium because no one was going to invest... Sikonathi Mantshantsha, deputy editor at Financial Mail, on intention to revoke MPRDA amendment bill. Exports facilitated by increasing Transnet rail capacity to RBCT. Production Export sales Local sales Eskom purchases Eskom burn South African Coal Roadmap steering committee chairperson Ian Hall: Burn vs Purchases (Mt) FY FY1 FY2 FY3 FY4 FY6 FY7 FY8 FY9 FY1 FY11 FY12 FY13 FY14 FY15 FY16 FY17 FY18 From 213 to 219, 12-million tons of new capacity need(ed)to come on stream. This did not occur The current coal supplies to State electricity utility Eskom will decline rapidly after 215, when existing large-scale mines' suppliers reach the end of their lives and require (expansion) recapitalisation. ST/MT Source: SAMI; Eskom PED FP CP Burn SA s exports expanded from India & China to include The Netherlands, Italy, Morocco, Egypt & Senegal.

14 Furthermore, bulk of export grade coal competes with Eskom s boiler specifications South African thermal coal exports from all ports Million ton >6,2 kcal/kg, NAR 5,-5,6 kcal/kg, NAR 5,6-6,2 kcal/kg, NAR 4,2-5, kcal/kg, NAR <4,2 kcal/kg, NAR Eskom Grade Coal Minerals Council of SA (nee Chamber of Mines) Coal Strategy 218, forecasts that India s coal demand will continue to increase in the foreseeable future, best case will be that exports remain constant Investment capital may also not be available in the future, as financing for coal based energy is reducing, thus coal mining investment is uncertain which will further constrain coal supply as Eskom will be competing against the export market for this limited supply Eskom must guard itself in this limited supply environment by signing long term coal supply agreements which will ensure security of coal supply and hedge against price fluctuations Source: IHS Markit

15 Eskom faces a coal supply shortfall, however has a plan to remedy the problem on long term basis Causes of coal supply shortages Long term coal strategy pillars Unsuccessful negotiations to extend Arnot Power Station tied colliery coal supply agreement Kusile long term tied colliery coal contracts did not materialize (makes up the bulk of the 1 318Mt shortfall) Contract negotiations to extend the Hendrina tied colliery coal contract discontinued Lack of capital investment in the at four of the five cost plus mines resulting in reduced production mines producing at 68% of contractual Limited investment in RSA in opening new large scale mines Increased export volume of Eskom grade coal Extension of cost plus mines for total reserves to match power stations life. Investment in cost plus mines to access remaining reserves for contractual volumes Extension of the tied long term fixed price collieries Expansion of domestic rail infrastructure for Eskom by Transnet Coal open tenders to source coal for the remaining life of power stations

Investing in cost plus mines is integral to Eskom s long term coal strategy. Investment in cost plus mines and extension of cost plus agreements is required to secure coal volume. Steady state coal supply and costs is anticipated from about FY23/24 based on investments taking place as planned Impact of not investing in cost plus mines will result in further reduction in coal from these mines and an increase in expenditure on short/medium term coal.

17 and manage increases in cost of coal burnt to generate electricity RSA has experienced limited investment in new coal mines, especially new large mines. Eskom has been increasingly competing for coal with other buyers, especially seaborne. Annual increases in coal R/ton cost have been impacted by lower production at cost plus mines and increasing costs of replacement coal due to associated transport costs. Eskom intends to: Increase or contract coal from suppliers closest to the Eskom Power Stations Invest in Cost Plus mines Secure long term coal contracts through life of Power Station open tenders Procure coal through transparent coal procurement mechanisms in line with Preferential Procurement Policy Framework Act regulations. Seek and strive to manage coal cost increases over MYPD application periods estimated at less than 1% per annum on a CAGR basis

20 Principles of Section 34 procurement In Terms of Regulations of Electricity Regulation Act (ERA), Minister of Energy makes a determination that Eskom be buyer of energy from IPP s Before signing a Power Purchase Agreement (PPA), the Regulations also require Eskom to ensure that it meets requirement for value for money and also ensure PPA meets requirements of Electricity Regulation Act, Public Finance Management Act, Companies Act and all applicable legislation before signing in line with Board s fiduciary duties When Eskom makes an MYPD revenue application, Eskom estimates future costs of actual purchases of power from IPPs as well as administration costs (employee benefits, depreciation, travel and subsistence, legal costs, office costs). NERSA assesses costs as forecasted by Eskom for future period covered by the particular MYPD revenue application, and if NERSA deems it appropriate it will substitute a different assumption regarding these future costs, for the purpose of its revenue determination. IPP costs are included in the revenue allowance made to Eskom and are subsequently included in the calculations of the Eskom tariffs to customers. Therefore, Eskom recovers these costs through revenue when customers pay Eskom, same as for Eskom s other costs. After the end of the financial year, when Eskom submits the Regulatory Clearance Account (RCA) application, a comparison is made of the assumed costs as included in the MYPD revenue determination versus the actual costs incurred i.e. payments to IPPs for the year, to determine if there was an over recovery or under recovery Eskom will be refunded (by virtue of an add-on to future allowed revenues thus tariffs) for an under recovery and for an over recovery Eskom will have a reduction of the RCA amount (thus a deduction from future allowed
