Feature Article: The Electricity Crisis - Bad to Terrible to Even Worse!
On 7 August, 2012, the FMF published my article The Electricity Crisis - from Bad to Terrible which concluded, "Medupi power station will be 48 months late and cost at least R77.1bn more than the original estimate". I was being optimistic. Since then the issues surrounding the construction of Medupi power station have deteriorated at an astonishing rate.
Eskom's press release issued earlier this week, stated that "As a result of the longer than expected construction time, the cost to completion of Medupi is now expected to increase to a maximum of R105-billion (excluding interest during construction, transmission costs and claims against contractors), from the previous estimate of R91.2-billion. The increase will be funded from existing capex allocations and will not impact electricity tariffs. The cost of Medupi remains within international benchmarks".
But the price they tell us is not the price we will be paying. Include the conservatively estimated R30bn interest during construction (IDC) and the price of Medupi immediately jumps from R105bn to R135bn. This figure, however, excludes the cost of the flue gas desulphurisation (FGD) plant also required, which adds on another R10bn to R15bn. Thus Medupi is more likely to cost us between R145bn and R150bn, which is considerably higher than Eskom's estimate. At the price of R150bn for a 4,764MW station, which equates to R31.4m/MW, Medupiwill be one of, if not, the most expensive coal-fired power stations in the world.
But we should not stop there. The opportunity costs, or indirect costs, of an additional six month delay must also be factored into any calculations. Using the cost of unserved energy (COUE)figure, which incorporates the losses suffered in the economy as a whole due to unavailability of energy, from South Africa's Integrated Resource Plan of 2010 (IRP 2010) of R75/kWh, the cost of this delay will amount to R234bn. If we are optimistic and use the lower COUE figure from the IRP 2010 of R10/kWh, the cost of the delay amounts to a scandalous R31bn.
Adding more gloom to the doom, we have to be prepared for the probability that there will be knock-on effects and all six of the units at Medupi will be delayed. The total COUE for a delay on six units amounts to a staggering R1.408 trillion (R1,408,000,000,000) at R75/kWh (or R186bn at R10/kWh). Regardless of which COUE figure we use, the economic impact on the South Africa's wider economy is horrendous.
