THE NATIONAL ENERGY REGULATOR OF SOUTH AFRICA In the matter regarding THE 2020, 2021 AND 2023 TARIFF APPLICATION FOR THE STORAGE FACILITY IN CAPE TOWN HARBOUR, WESTERN CAPE PROVINCE By FFS REFINERS (PTY) LTD (LICENCE NUMBER: PPL.SF/F3/80/10/2008) THE DECISION 1. On 10 September 2020, the National Energy Regulator of South Africa (NERSA or ‘the Energy Regulator’) approved tariffs for the 2020 Financial Year (FY), 2021 FY and 2022 FY, as a condition of FFS Refiners (Pty) Ltd’s operation licence, for the operation of its petroleum storage facility located at Cape Town Harbour Tank Farm in Western Cape Province (Licence Number: PPL.sf.F3/80/10/2008). 2. The tariffs approved by NERSA for the petroleum storage facility are maximum tariffs, expressed in Rands per cubic metre (R/m3/month) and are exclusive of the Value Added Tax (VAT). The tariffs for the petroleum storage facility are shown in Table 1 below. Table 1: Tariff approved for the storage facility 2020 2021 2022 (R/m3/month) (R/m3/month) (R/m3/month) FFS Refiners 423 460 441 3. The tariffs will be applicable for the periods starting from 10 September 2020 to 31 December 2020, 1 January 2021 to 31 December 2021, 1 January 2022 to 31 December 2022. Upon lapsed of the 2022 tariff period, the 2022 tariff will remain in force until NERSA takes a decision to approve a new tariff for the storage facility in line with section 28(5)(b) of the Petroleum Pipelines Act, 2003 (Act No. 60 of 2003) [‘the Act’]. 4. Although NERSA approved the tariffs applied for, for future tariff applications, FFS is required to use the elements of the Allowable Revenue (AR) calculated by NERSA and/or the actual costs incurred as a base when submitting future tariff applications. The elements of AR determined by the Energy Regulator may still be subjected to a further prudency assessment and verification. Page 4 of 17
5. Furthermore, FFS is required to comply with the requirements of Regulation 9 of the Regulations made in terms of section 33(1) of the Act (‘the Regulations’) and make a financial provision for the rehabilitation of land used in connection with the licensed activity. Page 5 of 17
REASONS FOR DECISION Introduction 1. On 8 January 2010, the National Energy Regulator South Africa (NERSA or ‘the Energy Regulator) issued a license with conditions to FFS Refiners (Pty) Ltd to operate its petroleum storage facility located at Cape Town Harbour Tank Farm in Western Cape Province (License number: PPL.sf.F3/80/10/2008). The facility is owned and operated by FFS Refiners, a privately owned company with limited liability established in terms of the Companies Act, 1973 (Act No.61 of 1973). 2. On 22 September 2014, the Energy Regulator approved the first amendment of the conditions of a licence issued to FFS for the operation of its petroleum storage facility at Cape Town Harbour Tank Farm in Western Cape Province. 3. The amendment sought to add a new storage tank. After the amendment, the Cape Town Harbour facility consists of five storage tanks. 4. FFS is a private company registered in terms of the company laws of South Africa, with Company Registration No. 1986/003962/07. FFS Refiners recycles and stores a variety of used petroleum products. 5. On 20 February 2020, FFS submitted a tariff application for its Cape Town Harbour storage facility for the period 1 January 2020 to 31 December 2022 (3 years). The application was declared adequate on 2 March 2020. 6. This is the FFS’s first tariff application after amendment of the conditions of the licence. 7. The application is based on the Tariff Methodology for the approval of Tariffs for Petroleum Loading Facilities and Petroleum Storage Facilities, Version 4, approved on 24 August 20171 (‘the Tariff Methodology’). 1 Available at www.nersa.org.za Page 6 of 17
8. In this tariff application, FFS is applying for tariffs of R430/m3/month for the 2020 FY, R1 446/m3/month for the 2021 FY and R463/m3/month for the 2022 FY. The tariffs applied for are maximum tariffs and are exclusive of Value Added Tax (VAT). The tariff application by FFS is based on the Tariff Methodology for the approval of Tariffs for Petroleum Loading Facilities and Petroleum Storage Facilities, Version 4, approved on 24 August 2017 (‘the Tariff Methodology’). Applicable Law 9. The legal basis for NERSA to approve tariffs for petroleum loading and storage facilities is derived from the National Energy Regulator Act, 2004 (Act No. 40 of 2004) (‘NERSA Act’), read with the Petroleum Pipelines Act, 2003 (Act No. 60 of 2003) (‘the Act’)2. The Methodology 10. NERSA is required by section 28(2)(a)(i) of the Act to approve tariffs based on a systematic methodology applicable on a consistent and comparable basis. The tariff application by the FFS was prepared using the Tariff Methodology. 11. The Tariff Methodology prescribes the use of the Trended Original Cost (TOC) method for the valuation of assets. 12. FFS has in this case used the TOC valuation method to determine its Property, Plant, Vehicles and Equipment (PPE) values. Decision-Making Process 13. As part of the public consultation process, NERSA published the non-confidential version of the tariff application on its website for public comment. Notices inviting the public to submit written comments on the tariff application were published in the Beeld and the Business Day Newspapers on 24 June 2020. The closing date for receiving public comments was 4 August 2020. The public participation process was carried out in accordance to section 4 of the Promotion of Administrative Justice Act, 2000 (Act No. 3 of 2000). 14. No comments were received from stakeholders or members of the public by closing date. 2 Available at www.nersa.org.za Page 7 of 17
15. Due to the COVID-19 pandemic restrictions, the Energy Regulator waived the public hearing for this application. NERSA considers the request for submission of written comments as a sufficient form of public consultation for this application. THE APPLICATION Assessment of the Application 16. NERSA used the TOC Tariff Methodology to assess the outcome of the tariffs applied for by FFS for the Cape Town Harbour storage facility. 17. Data supplied by FFS was used for most of the calculations performed in this evaluation. Where this is not the case, the reasons for not using the FFS’ supplied data are provided. Calculation of the Allowable Revenue (AR) 18. In accordance with the Tariff Methodology, the following formula was used to determine the FFS’ AR: AR = (RAB x WACC) + E + D ± C +T Where: RAB = Regulatory Asset Base WACC = Weighted Average Cost of Capital E = Expenses: Operating and Maintenance Expenses for the tariff period under review D = Depreciation Expense for the tariff period under review C = Clawback Adjustment from a preceding tariff period in relation to the latest estimates for that tariff period T = Tax: estimated Tax Expense for the tariff period under review 19. The elements of the AR are discussed in more detail in the paragraphs below. Regulatory Asset Base (RAB) 20. According to the Tariff Methodology, RAB is to be determined by applying the following formula: Page 8 of 17
RAB = (V - d) + w ± dtax Where: V = Value of Operating Property, Plant, Vehicles and Equipment d = Accumulated Depreciation and Accumulated Amortisation of inflation write-up for the period up to the commencement of the tariff period under review w = Net Working Capital dtax = Deferred Tax Property, Plant and Equipment (PPE) 21. FFS states that the Starting Regulatory Asset Base (SRAB) as approved by NERSA has been trended to arrive at the qualifying RAB values for each tariff period. The TOC asset valuation method was used in accordance with the Tariff Methodology. The SRAB was trended using the Consumer Price Index forecast (CPIf). 22. In its application, FFS determined the PPE values of R199.57 million, R202.75 million, and R205.16 million for the 2020 FY, 2021 FY, 2022 FY, respectively. NERSA calculated the PPE value to be R200.52 million, R204.69 million, and R208.70 million for the 2020 FY, 2021 FY, 2022 FY, respectively. 23. The difference between the PPE value submitted by FFS and those determined by NERSA emanates from the different Consumer Price Index forecast (CPIf) values used in trending the asset values. NERSA used the most recent CPIf for the period under review (5.60%), while FFS used the latest CPIf available at the time the tariff application was compiled (5.10%). The CPIf data used by NERSA was sourced from the Bureau of Economic Research (BER) and is published on the NERSA website. 24. Any difference between the asset values used in the determination of tariffs and the actual prudently incurred costs will be subject to clawback in the subsequent tariff periods, once the audited costs are submitted and verified through the Regulatory Reporting Manuals (RRM). Page 9 of 17
Net Working Capital 25. Net Working Capital (w) refers to the various regulated business operation’s funding requirements other than PPE in service. These funding requirements include Inventories, Trade Receivables, Operating Cash and Trade Payables. 26. The following formula from the Tariff Methodology was used to determine the Net Working Capital. Net Working Capital = Inventory + Trade Receivables + Operating Cash – Trade Payables 27. FFS calculated its working capital by considering the following elements: Trade receivables are based on 30 days of turnover based on current customer contract; External trade payables are settled within 45 days; and The allowance for operating cash is taken as a standardized factor of 45 days operating expenditure. 28. NERSA calculated the net working capital based on 30 days of AR for receivables, operating cash is based on 45 days of operating expenditure (opex) and trade payables are based on 45 days of operating expenditure. The comparison of working capital is shown in Table 2 below. Table 2: Calculation of Net Working Capital FFS NERSA Net Working Capital R’000 2020 2021 2022 2020 2021 2022 AR 76 965 79 816 82 742 75 637 78 854 82 293 Operating Expenses 31 505 33 402 35 518 31 505 33 402 35 518 Receivables 6 195 6 449 6 755 6 126 6 386 6 665 Operating cash 2 582 2 745 2 919 3 884 4 118 4 379 Less Payables (2 582) (2 745) (2 919) (3 884) (4 118) (4 379) Net Working 6 195 6 449 6 755 6 126 6 386 6 665 Capital 29. The difference between the Net Working Capital calculated by FFS and NERSA is due to the different AR values used in determining the Trade Receivables value and also the different days used to calculate operating cash and trade receivables. Page 10 of 17
30. The Net Working Capital and the PPE value were added to determine the RAB value on which a return is earned. The RAB values are depicted in Table 3 below. Table 3: Calculation of the RAB FFS NERSA Net Working Capital (R’000) 2020 2021 2022 2020 2021 2022 PPE-d 199 567 202 753 205 159 200 516 204 687 208 696 Net Working 6 195 6 449 6 755 6 126 6 386 6 665 Capital - - - - - - Dtax(liability) RAB 205 762 209 642 211 914 206 642 211 073 215 361 31. The difference in the RAB values calculated by FFS and NERSA is due to the difference in the PPE and Net Working Capital values calculated by both parties. Weighted Average Cost of Capital (WACC) 32. Section 5 of the Tariff Methodology stipulates that the following formula must be used to determine the WACC: E q D t W A C C * K e * K d D t E q D t E q Where: Eq = Shareholders’ Equity Dt = Interest Bearing Debt Ke = Post-tax, real Cost of Equity derived from the Capital Asset Pricing Model (CAPM) Kd = Post-tax, real3 Cost of Debt 33. In the tariff application, FFS states that the WACC calculation is in line with the Tariff Methodology. In calculating the WACC, the following components of the WACC were analysed: a) Cost of Equity; b) Cost of Debt; and c) Debt to Equity Ratio. 3 First convert from pre- to post-tax and then from nominal to real. Page 11 of 17
Cost of Equity 34. The Tariff Methodology prescribes that the Cost of Equity be determined according to the Capital Asset Pricing Model (CAPM). FFS applied the CAPM to calculate their Cost of Equity. 35. FFS applied a Risk Free Rate (Rf) of 5.30%, a Market Risk Premium (MRP) of 5.20% and Beta of 0.82, which resulted in a Cost of Equity of 18.56%. 36. NERSA applied a Rf of 5.31%, MRP of 4.75% and a Beta of 0.75, which resulted in a Cost of Equity of 17.87%. 37. The Tariff Methodology requires that data used to calculate the Cost of Equity be that of 12 months prior to the commencement of the tariff period under review. In this regard, the data used by NERSA in its determination of Cost of Equity is that of December 2018, while FFS used data as at August 2018, hence the difference between the Cost of Equity values. Cost of Debt 38. FFS calculated a Cost of Debt of 2.00% (post-tax, real) using a CPIf for the tariff period under review of 5.10% and a nominal Cost of Debt of 10.0% for the tariff periods under review. 39. NERSA calculated a real Cost of Debt of 1.52% using the most recent CPIf for the period under review, namely 5.60% and a nominal Cost of Debt of 10%. Therefore, NERSA’s and the FFS’ calculations differ due to the use of different CPIf values. Debt to Equity Ratio 40. The Tariff Methodology requires a minimum debt to equity ratio of 30:70 for the efficient operation of the licenced activity. 41. The Tariff Methodology states that, “the actual interest bearing debt and the equity pertaining to the regulated assets for the tariff period under review must be subject to the Energy Regulator finding the licensee’s debt to equity ratio reasonable. If after conducting reasonableness checks, the Energy Regulator finds the debt ratio to be unreasonable, the Energy Regulator must assume a reasonable debt ratio. A minimum debt to total capital level of 30% will be assumed reasonable”. Page 12 of 17
42. FFS indicated that its actual debt ratio to equity ratio is 20:80. Therefore, FFS had to base its calculations on the minimum debt to equity ratio of 30:70 in calculating its WACC value. 43. NERSA also used a debt to equity ratio of 30:70 in determining its WACC as the Tariff Methodology requires a minimum debt to equity ratio of 30:70 for the efficient operation of the licenced activity. WACC 44. FFS calculated its real WACC to be 13.59% and NERSA calculated a WACC of 13%. The difference in the WACC calculated by FFS and that calculated by NERSA is due to the different Cost of Equity and Cost of Debt values. The WACC calculation by the FFS and by NERSA is depicted in Table 3 below. Table 3: WACC calculation Detail Formula FFS NERSA Risk Free Rate (before-tax real) a 5.30% 5.31% Market Risk Premium (real) b 5.20% 4.75% Beta c 0.82 0.75 Cost of Equity (post-tax real) e=(a+(b*c)) 18.56% 17.87% Cost of Debt (Pre-tax) e 10.00% 10.25% Corporate tax rate f 28% 28% Nominal Cost of Debt g=e*(1-f) 7.20% 7.20% CPI forecast h 5.10% 5.60% Cost of Debt (post-tax real) I=(1+g)/(1+h)-1 2.00% 1.52% Capital Structure: Debt ratio j 30% 30% Equity Ratio k 70% 70% WACC l=(d*k)+(i*j) 13.59% 13.00% Operating Expenditure (E) 45. Regulation 5(2) read with regulation 4(2)(a) of the Regulations made under the Petroleum Pipelines Act, 2003 (Act No. 60 of 2003) [‘the Regulations’], provides that the tariffs approved by the Energy Regulator must enable an efficient licensee to recover the reasonable operational and maintenance expenses of the storage facility in the year in which they are incurred. 46. The FFS licensed storage facility does not generate any revenue from external customers, as the facility is used entirely for FFS’s own use. The licensed activity Page 13 of 17
accounts for 80% of the group’s total expenses allocated according to throughput percentage. 47. FFS states that expenses are planned for the efficient operation and maintenance of the core business. These expenses are to be categorised in accordance with the Regulatory Reporting Manual (RRM). The fully allocated cost attribution approach for the allocation of costs is used. 48. NERSA accepts the operational expenses projections by FFS. (refer to Table 4). Any difference between the expenses provided in this tariff application and actual expenses incurred will be subject to a giveback or clawback in the next tariff period. 49. The yearly increases of estimated expenses are based on a CPI values for the tariff periods applied for. The CPI forecasts are published on the Energy Regulator’s website and are sourced from the BER. Table 4: Operating Expense 2020 2021 2022 Expense Description R R R Fixed Cost 31 505 000 33 402 000 35 518 000 Total 31 505 000 33 402 000 35 518 000 50. NERSA allows the projected costs subject to further verifications and audits. Any difference between the expenses provided in this tariff application and actual expenses incurred would be subject to a clawback in favour of the customers or FFS in the next tariff determinations. Depreciation (D) 51. Section 8.1 of the Tariff Methodology prescribes that Depreciation be calculated on a straight line basis over the service life of each of the assets or classes of assets. 52. FFS depreciated its assets on a straight line basis using the useful life of 25 years and arrived at the values of R6.33 million for the 2020 FY, 2021 FY and 2022 FY. 53. NERSA also applied a straight line basis to calculate depreciation and arrived at the same values for the 2020 FY, 2021 FY and 2022 FY. Page 14 of 17
Tax Allowance (T) 54. Section 7.1 of the Tariff Methodology states that: “Each licensee must make a once off election between the use of either (a) flow-through (actual tax) payment, or (b) notional tax payment”. 55. FFS has elected to use notional tax. NERSA interprets a notional tax expense to mean the tax due according to accounting requirements rather than the actual tax payable in the period under review. 56. Section 7.3 of the Tariff Methodology prescribes the following formula for calculating the notional tax expense: Tax = {(NRBTA)/ (1-t)*t} Where: NRBTA = Net Revenue before Tax Allowance = {(RAB*WACC) + E + D (historic & write up) ±C} - {E + Depreciation (historic))} t = Prevailing Corporate Tax Rate of the licensee 57. The tax calculation is shown in Table 5 below. Table 5: Tax Expense Calculation FFS NERSA R’000 2020 2021 2022 2020 2021 2022 Allowable Revenue before tax 66 008 68 592 71 291 65 052 67 900 70 968 allowance Less: Operational Expenses 31 505 33 402 35 518 31 505 33 402 35 518 Less: Depreciation (historic) 6 329 6 329 6 329 6 329 6 329 6 329 Less: Clawback 0 0 0 0 0 0 Taxable income before Gross 28 174 28 861 29 444 27 218 28 168 29 121 up Taxable income after Gross 39 131 40 084 40 895 37 803 39 123 40 446 up (taxable income/1-t) Tax Component in income 10 957 10 585 11 451 10 585 10 954 11 325 (i.e. Gross up * 28%) 58. Table 5 above shows that there is a difference in tax allowance expense due to a different AR (before tax) being used by FFS and NERSA in calculating tax expense. Page 15 of 17
Allowable Revenue (AR) 59. FFS calculated the AR based on Rate of Return (ROR) approach. This is in accordance with the Tariff Methodology. 60. NERSA also performed the calculations of AR based on the ROR approach. The comparison between the AR calculated by FFS and NERSA are shown in Table 6 below. Table 6: AR Calculation FFS NERSA R’000 2020 2021 2022 2020 2021 2022 Asset value (PPE – d) – ToC 199 567 202 753 205 159 200 516 204 687 208 696 Net Working Capital (w) 6 195 6 449 6 755 6 126 6 386 6 665 RAB 205 762 209 642 211 914 206 642 211 073 215 361 Ke 18.56% 18.56% 18.56% 17.87% 17.87% 17.87% Kd 2.00% 2.00% 2.00% 1.52% 1.52% 1.52% WACC 13.59% 13.59% 13.59% 13.00% 13.00% 13.00% Return on Investment 27 851 28 198 28 447 26 864 27 440 27 997 Operating Expenses 31 505 33 402 35 518 31 505 33 402 35 518 Depreciation 6 329 6 329 6 329 6 329 6 329 6 329 Amortisation 323 662 998 354 729 1 124 Tax Expense 10 957 11 224 11 451 10 585 10 954 11 325 Allowable Revenue 76 965 79 816 82 742 75 636 78 854 82 293 61. The difference in AR is mainly due to the RAB, WACC, tax expenses and Amortisation calculated by FFS and NERSA. Volumes 62. FFS states that Cape Town Harbour Depot is totally committed to Petro SA and Eskom as a strategic stockholding, no estimate of volume throughput can be given. The throughput depends totally on the availability of electricity through the Eskom grid and the extent that Eskom needs to run the emergency peaking plant generators. FFS has assumed 12 stock turns per annum. 63. NERSA accepts the use of total operating capacity as proposed way of estimating volumes for FFS. NERSA will continuously monitor this against the volumes submitted to NERSA on a monthly basis, any difference will be subject to a clawback adjustment in future tariff periods. Page 16 of 17
Tariff 64. The tariffs calculated by FFS and NERSA are based on the total AR divided by the total operating capacity. The proposed tariffs are expressed as Rands per cubic metre of tank capacity per month and are exclusive of VAT. 65. The tariffs calculated by FFS and NERSA are summarised in Table 7 below. Table 7: Tariff calculation FFS NERSA 2020 2021 2022 2020 2021 2022 Allowable Revenue (R’000) 76 965 79 816 82 742 75 637 78 854 82 293 Volume (m3) 179 179 179 179 179 179 Tariff ( Rands/m3 /month) 430 446 463 446 441 460 % difference 1.73% 1.20% 0.54% 66. The differences in the tariffs applied for by FFS and those determined by NERSA are due to the following: a) the RAB values in the application are different from those determined by the NERSA due to different net working capital and amortisation; b) the different WACC values for the tariff periods under review, resulted in different returns on investments due to the different Risk free, MRP and CPIf applied by both parties; and c) the different values in RAB, WACC resulted in different ARs and ultimately resulted in different tariffs. 67. FFS is required to use the elements of the AR calculated by NERSA and/or the actual costs incurred as a base when submitting future tariff applications. Conclusion 68. From a conspectus of the facts and evidence, it is appropriate and in compliance with the requirements of the National Energy Regulator Act, 2004 (Act No. 40 of 2004) to make the decision set out above. The decision finds a reasonable balance between the interests of customers on the one hand and the interests of investors on the other. Page 17 of 17
