Engagements with management at five of Eskom’s coal-fired power plants so far suggest it is technical and investment issues, and not corruption, adversely affecting the performance of the utility’s fleet, the newly appointed minister of electricity has said. Minister Kgosientsho Ramokgopa is visiting each of Eskom’s 15 power stations, including Koeberg. Speaking to the media during a visit to the Tutuka power station on Wednesday – the fifth of the plants which the minister will visit – Ramokgopa said he would not speak about corruption in aggregate terms.
