National Treasury says there are no conclusive figures to date on the financial affordability and social impact on procuring new nuclear plants for South Africa.
In a response to a parliamentary question released on Friday, Finance Minister Pravin Gordhan said studies released by the department of energy last week were based on limited information.
“These reports only contain preliminary observations, which were reached from limited information. Extensive work is still required before substantive conclusions are reached,” he replied to a question from Democratic Alliance finance spokesperson David Maynier.
“A full cost-benefit analysis must be conducted, which must include a comprehensive social and economic impact assessment before the feasibility, affordability and procurement strategy can be properly assessed by the Treasury.”
Gordhan added the office of the chief procurement office held discussions with the department of energy about the feasibility of the nuclear expansion programme last year. Following that, the finance ministry wrote to the department to convey its view, he said.
In September this year, the department then sent National Treasury a set of documents, including the reviews undertaken by the department’s transaction advisers.
Ten days later, Treasury sent the department a letter “outlining Treasury’s assessment on the state of readiness of the procurement strategy”.
It planned to engage further with the department once it was able to submit more substantive documentation, he said.
Last week, the department briefed Parliament’s portfolio committee on energy on the preliminary studies, conceding it was doing so reluctantly because it believed releasing the information would skewer the tender process for a nuclear build.
Eskom is preparing to go to the market with a request for proposals before the end of the year despite the newly released draft Integrated Resource Plan proposing a seven-year delay in the programme because its base case scenario projects 2037 as the commissioning date for the first new plant.
Business Day on Friday quoted director-general of finance Lungisa Fuzile as saying that Eskom’s current government guarantees totaling R350 billion may not be used to fund nuclear reactors.
“The R350 billion was never given for nuclear,” Fuzile said. “If Eskom were to want to use the guarantee for anything other than what was in the build programme they would have to come and negotiate with us.”
Gordhan has maintained that he would not approve a nuclear build programme the country cannot afford.
The potential cost of nuclear has become a political battle point, and critics of Eskom’s plans last week pointed out that if constraints in the IRP on renewables were removed, solar, wind and gas would be the cheapest energy supply mix and also meet security of supply requirements.
The reports the energy department released to the portfolio committee outlined 16 studies undertaken since 2008.
One of these, carried out by engineering consultancy group Ingerop, informed President Jacob Zuma’s announcement that South Africa would add 9 600 megawatt to the electricity grid and came up with an average capital cost of US 4 918/kWe.
This was higher that the figure publicly advanced by the department of energy’s deputy director-general Zizamele Mbambo last year.
Mbambo told parliament’s portfolio committee that after National Treasury conducted an analysis in 2015 and submitted its conclusions to Cabinet, it was concluded that “any further studies will not provide more accurate answers” and that the only way to get reliable information was to go to the market.
But this appears at odds with Gordhan’s call for comprehensive research.
