Abstract Formatted: No underline, English (UK) Deleted: : Mozambican Gas – An Economically Viable Solution to the South African Electricity Crisis? Formatted: No underline, English (UK) Formatted: English (UK)

The recent significant discoveries of gas in Mozambique could provide a much needed solution to the South African electricity crisis, but at what cost? This research report seeks to determine the economic viability of utilising Mozambican Gas to produce electricity by using data from the Integrated Resource Plan 2010-2030 Update of 2013 in a levelised cost of electricity model.

The Mozambican gas fields are yet to be developed and the final price at which gas will be available is unclear, but a price range determined by ICF international in a study for the World Bank is assumed for the purposes of the study, with the results yielding a range levelised cost of energy.

The results of the levelised cost determine that Mozambican gas can be utilised to provide an economical solution to the south African electricity crisis, but the price at which gas is available will determine the type of generation, either peaking power, mid- merit and or baseload generation.

Figure 3.1: Basic Principles of Turbines (Brain, nd) Open Cycle Gas Turbine (OCGT) An open cycle gas turbine is a stand-alone gas turbine combustion unit that is typically operated to meet peak load demands as they have short start-up and shutdown cycles. The typical size of these units are 100-400MW and they have thermal efficiency of around 35-40% (Price Waterhouse Coopers, 2015).

6.1 Occurrence and Estimation of Natural Gas in Mozambique Deleted: : Formatted: English (UK) The Gas industry in Mozambique was kick started in 2000 when Sasol conducted surveying activities in partnership with CMH S.A. (a subsidiary of ENH – the national hydrocarbon company) in a project aimed at developing 120 million Giga Joules of natural gas for use domestically and in South Africa (Republic of Mozambique Cabinet Council, 2014). This Deleted: REPUBLIC OF MOZAMBIQUE CABINET COUNCIL Formatted: English (UK) resulted in the exploration and production from the Pande and Temane onshore gas fields, along with the construction of an 865 km pipeline between Temane, Mozambique and Deleted: 865km Formatted: English (UK) Secunda, South Africa.

The most recent developments in Mozambican gas have been in the Rovuma basin in the Deleted: current Formatted: English (UK) north forming the bulk of new discoveries, together with the Mozambican Basin in the central part of the country.

8. METHODOLOGY - LEVELISED COST OF ENERGY Formatted: No underline, English (UK) Deleted: : Formatted: No underline, English (UK) In order to determine the economic viability of using Mozambican Gas in South Africa one Formatted: English (UK) needs to compare the cost of producing the energy from gas and compare this cost of other possible alternative electricity generating technologies. The levelised cost of energy Formatted: English (UK) Deleted: calculation is a tool that is used by the energy sector to compare the total cost of producing ... [363] Formatted: English (UK) energy from different technologies. The levelised cost of energy is an economic calculation Deleted: is a Formatted: English (UK) taking into account the the capital cost, fixed and variable operating costs while accounting Formatted: English (UK) for the weighted average cost of capital as well as time value of money. Deleted: ... [364] Formatted: English (UK)

Levelised cost of energy breaks down the capital, fixed and variable operating costs as well as fuel costs into a price per MWh. The result is the total price of producing electricity can be Deleted: mega watt hour. Formatted: English (UK) compared on a level basis of a unit of cost per MWh. The calculation of levelised cost of energy Deleted: Mwh. ... [365] can be calculated in the following manner: Formatted: English (UK)

Firstly, one would need to calculate the Adjusted Capital Cost. Overnight capital cost is the cost of the plant if it was to be built overnight, the reality is that power plants take several years to construct ranging from 18 months to 16 years (Department Of Energy, 2010), and Deleted: DOE Formatted: English (UK) are phased online over a period of time.

The adjusted capital cost accounts for the phasing of construction and the costs associated with that (Equation 8.1). Deleted: . Formatted: English (UK)

Adjusted Capital Cost = Overnight Capital Cost + Interest During Construction [8.1] Formatted: Right Formatted: Font:Bold, English (UK) Formatted: English (UK) Once the adjusted capital cost has been determined the Capital Recovery Factor (CRF) must Formatted: English (UK) be calculated in order to determine the levelised capital cost. Capital Recovery Factor Formatted: English (UK) (equation 8.2) is a ratio that determines that annual capital cost annuity for a set period of Deleted: ...

Annualised Capital (equation 8.3) is the amount of capital that the annuity or capital recovery Formatted: English (UK) factor allocates for each year that of the lifetime of the plant.

Formatted: English (UK) • Pulverised Coal with FGD - ZAR 584.14/MWh Formatted: English (UK) Formatted: English (UK)

The comparison of the cost to displace coal will be done on Pulverised Coal with flue gas desulphurisation as this is the most cost competitive. Carbon taxes have not been taken into Deleted: - carbon Formatted: English (UK) account in this calculation as mentioned above. Deleted: study Formatted: English (UK) Formatted: English (UK) The Result from the model is as follows as seen in appendix 2 Deleted: : Formatted: English (UK) • USD 6.511/MMBtu - ZAR 584.14/MWh

This is further supported by Stanley et al (2014), stating that gas imports via pipeline from Deleted: , Formatted: English (UK) Mozambique are currently competitive with coal at a delivered price of USD7/MMBtu (USD

7.39/Gj) or less. This estimate is also closely maintained by McKinsey (2015) stating that gas Deleted: (Stanley , et al., 2014). ... [378] Formatted: English (UK) prices would need to drop below USD6/MMbtu (USD 6.33/Gj) to begin to displace coal on the Deleted: supported cost curve. Formatted: English (UK) Deleted: , Formatted: English (UK) 9.3.2 Price of Gas to Displace Nuclear Deleted: states that “ Formatted: English (UK) According to the IRP 2010-2030 update there are the following costs of producing nuclear Deleted: ” (Mckinsey , 2015). power as seen in appendix 2: Formatted: English (UK) Deleted: : • Nuclear Fleet Cost - ZAR 692.83/MWh Formatted: English (UK) Formatted: English (UK) The cost of gas needed to displace the cost of nuclear power according the the levelised cost of energy model is:

• USD 8.229/MMBtu - ZAR 692.85/MWh

85

Figure 9.3 illustrates that landing gas in the lower quartile of the cost estimate would result Deleted: 15 Formatted: English (UK) in gas displacing the cost of new coal assets as well as nuclear alternatives.

The Mozambican onshore gas processing facilities timeline is more uncertain than the LNG facilities but based on the cost assumptions in this paper the integration of Mozambican Gas via pipeline presents a credible opportunity that stakeholders should be perusing.

10. Conclusion and Recommendations Deleted: & Formatted: No underline, English (UK) Deleted: : Mozambican Gas has the potential to provide an economically viable solution to the South Formatted: No underline, English (UK) African power crisis, but the final price at which South Africa can buy the gas is unclear due Formatted: No underline, English (UK) Formatted: English (UK) to the early stage of development the gas fields are currently in. The cost assumption made Formatted: Line spacing: 1.5 lines in this study (based on the IRP 2010-2030 Update of 2013) show that based on current Deleted: ... [379] Formatted: English (UK) information Mozambican gas could provide an economic solution to South Africa’s electricity Deleted: ... [380] crisis. Taking all these factors into account it is clear that the Government should be Formatted: English (UK) Deleted: ... [381] prioritising a Big Gas scenario utilising gas for peaking power, mid merit and baseload capacity Formatted: English (UK) expansion. Adopting the Big Gas approach based on the current available information offers Deleted: ... [382] Formatted: English (UK) a feasible way for South Africa to meet its current and future electricity shortfalls.

10.1 What is the Big Gas Scenario?

A Big Gas scenario according to the IRP 2010-2030, a big gas scenario would mean 62 480 MW Deleted: big gas Formatted: English (UK) of CCGT and 6720 MW of OCGT totalling 69 200 MW of installed power being gas, resulting Deleted: in 65.34% of total installed capacity would be power generated from gas with the balance made Formatted: English (UK) up of hydro, coal and renewables.

10.2 Implementation

Gas infrastructure has the shortest lead time and the lowest capital requirement of any power generation technology as discussed in Chapter 3. The fact that coal fired powered plants have Deleted: chapter Formatted: English (UK) a lead time of approximately eight years, and nuclear could take significantly longer due to Deleted: ... [383] the technical complexity (Mckinsey , 2015). This means that no new coal and nuclear Formatted: English (UK) expansion will be ready by at least 2026, and the renewable build program will not generate enough additional electricity to meet demand putting significant stress on the power supply system.

LNG gas Infrastructure can be implemented over the short to medium alleviating the immediate pressure on the electricity system while a pipeline for gas is being built in order to land gas at the cheapest possible price to integrate gas baseload electricity generation. All Deleted: ... [384] Formatted: English (UK) this can be achieved before any coal or nuclear assets would be integrated into the power supply pool. 87

10.3 Capital Cost Savings

Gas power stations need significantly less capital per unit capacity and achieve a similar and competitive levelised cost of electricity, this means that the investment is a more feasible Deleted: (as discussed above) Formatted: English (UK) option for the financially distressed Eskom or a more attractive investment to possible

Independent Power Producers. Adopting the Big Gas scenario would drastically change Deleted: Annexure envisaged energy mix (base case) of the IRP 2010-2030, but based on the assumes figures in Formatted: English (UK) this study could result in a very similar or better levelised cost per KWh, with a significantly reduced capital outlay.

Appendix 3 is an extract from Mckinsey (2015) report from this it is clear to see the Deleted: Annexure Formatted: English (UK) dramatically reduced capital expenditure a Big Gas adoption would realise. Over R 244 billion Deleted: the would be saved (a saving of 29% on capital expenditure) to realise a similar levelised cost of Formatted: English (UK) Formatted: English (UK) electricity (Mckinsey , 2015). In order to adopt a Big Gas scenario where gas would be used Deleted: for the full range of capacity including base load generation, (therefore displacing coal and ... [385] Formatted: English (UK) nuclear) gas prices would have to be in the region of USD 7/MMBtu. Deleted: big gas Formatted: English (UK) 10.4 Shale Gas Opportunity Deleted: ... [386] Formatted: English (UK)

The largest potential upside of developing a “Big Gas” scenario is the possibility of shale gas Deleted: big gas Formatted: English (UK) development and production in South Africa. If the development of the shale gas is successful Deleted: if the source can be switched to the domestic shale gas, potential utilising cheaper domestic Formatted: English (UK) gas for power, which will change the energy dynamics in South Africa significantly.

10.5 Downstream Gas Opportunities

Once the gas infrastructure is in place and gas is further integrated in the downstream sector, Formatted: English (UK) gas utilisation can be expanded into the industrial, transport and residential sectors creating a larger demand base which could offset the transport costs, possibility reducing the cost of gas further. The volume of gas that can be transported through a pipeline increases Deleted: ... [387] Formatted: English (UK) exponentially with the increase in the diameter of the pipe, costs on the other hand an Deleted: , increase more or less linearly (Stanley et al., 2014). “The combination of exponential volumes Formatted: English (UK) Deleted: and liner costs leads to powerful economies of scale in the unit cost of pipeline ... [388] Formatted: English (UK) 88 transportation” (Stanley et al., 2014). The development of a downstream gas sector in South Deleted: , Deleted: Africa would go a long way in creating new manufacturing hubs aiding in the creation of much ... [389] Formatted: English (UK) needed jobs and contributing significantly to the Gross Domestic Product. Formatted: English (UK) Deleted: adding Formatted: English (UK) 10.6 Recommendations Deleted: creating Formatted: English (UK) Formatted: English (UK) The South African Government needs to lead the process by firstly updating its stance on Deleted: : Formatted: English (UK) natural gas, identifying the recent Mozambican gas fields as a Mozambique as a key potential Formatted: English (UK) source of gas. The Integrated Resource Plan as the steering document must to be updated to Deleted: it Formatted: English (UK) reflect the Mozambican gas as a potential source of gas to produce economically viable Deleted: sighting electricity for the South African market. The Integrated Resource Plan must also update the Formatted: English (UK) Deleted: Gas. ... [390] effects of the exchange rate on the levelised cost of energy for each of the electricity Formatted: English (UK) generating options in order to get an accurate cost of gas, that can displace coal and nuclear Deleted: ... [391] Formatted: English (UK) options in order that the Big Gas scenario can be adopted.

Once these updated numbers have been determined, the ministry of energy needs to start approaching South Africa gas stakeholders in order that a combined approach can be made to the Mozambican gas stakeholders in order to acquire additional and more accurate information about the costs of LNG and Natural Gas to determine with certainty the cost that gas would be available to the South African market. Once this has been established the Deleted: ... [392] Formatted: English (UK) ministry can then make an informed decision about how to move forward with gas development before any other commitments are made to other new build technologies, specifically nuclear.
