Transitioning away from coal It has been over three years since Eskom announced the imminent closure of five of its coal-fired power stations.

E

skom’s announcement was generally welcomed as one of the necessar y steps on the road towards meeting the countr y’s environmental commitments as a signator y to the Paris Accord. At the same time, however, this announcement gave new vigour to the concerns about the fate of workers and communities whose livelihoods depend on the coal economy. It was clear that a just transition from a coal-intensive energy system to a lowcarbon future would be needed. Such a transition would also have to be fair to energy users, offering them affordable prices and access to electricity. “The key argument behind a just transition is that our move away from coal must be a process that is well managed, with a phased approach and clear guidelines

that are followed in a planned manner. Importantly, this is an approach that the trade unions also support,” says Andrew van Zyl, director and principal consultant, SRK Consulting. Eskom CEO André de Ruyter has reaffirmed the utility’s commitment to contributing to global efforts to address climate change, but without deser ting employees and their communities Currently, coal generates 92% of South Africa’s electricity. In addition to new power stations Medupi and Kusile, Eskom has at least two other power stations with lifespans of another 35 to 40 years. With coal reser ves for another 100 years, the latter two face little chance of being shut down earlier than that. “The remaining life of many of the other generating facilities really depends on

their mechanical costs. If the investment is affordable, a number of facilities could still be run for another 20 years or more, taking us to 2040 or later for a ‘final’ transition date away from coal,” says Noddy McGeorge, principal mining engineer, SRK Consulting.

Social and economic transition The process towards tr ying to understand the social impacts of this transition, though, is already under way. “For the past couple of years, Eskom has been requesting technical input on what the likely socio-economic impact will be when power stations are closed. The closure process is likely to involve similar issues to the closure of the associated coal mines – such as the reskilling of employees, economic resilience of communities and
