Diesel supply problem blamed for low OCGT use during intense loadshedding week

Eskom has confirmed that problems in the diesel supply chain last week meant that it did not operate its open-cycle gas turbines (OCGTs) as “hard” as it would have done normally in a context where the utility was resorting to Stage 6 loadshedding. Head of generation Bheki Nxumalo did not offer any details on the nature of the supply-chain problems during a weekly update on the Energy Action Plan.

Growthpoint wheels first renewable electricity through Cape Town pilot project

JSE-listed real estate investment trust Growthpoint Properties South Africa has become the first party in South Africa to wheel renewable electricity through Cape Town’s energy grid, in collaboration with electricity trading company Etana Energy.

Wheeling involves electricity being bought and sold between private parties and being transported from where it is generated to end-users over long distances.

Renewables hosting capacity of existing Western Cape grid could be doubled with 10% curtailment

A preliminary analysis by two leading European transmission system operators (TSOs) shows that the capacity of the existing Western Cape grid alone to host variable renewable generators could be doubled under a scenario where no more than 10% curtailment is implemented. Curtailment involves the active reduction of output from wind and solar plants in response to system security needs or temporary transmission capacity constraints and is widely used by system operators to facilitate the introduction of renewable generators in a context of grid constraints.

Energy council CEO sees 2023 as a turning point in the energy crisis, but warns of slow …

Industry body the Energy Council of South Africa CEO James Mackay has said there is sufficient reason to believe that loadshedding could end as early as the end of 2024, but warns that South Africa is not on track to meet its decarbonisation targets. Mackay was speaking at the Solutions From the Edge conference, hosted by housing financing organsiation International Housing Solutions and financial institution Nedbank Corporate and Investment Banking, in Johannesburg, on September 14.

SIU’s Mothibi says contents of private Eskom investigation ‘cannot be ignored’

Special Investigating Unit head Advocate Andy Mothibi says the fact that former Eskom CEO André de Ruyter did not receive board authorisation to commission a private intelligence investigation into criminality and sabotage at the State-owned utility raises potentially grave governance issues. Nevertheless, he stresses that the report’s content “cannot be ignored” and is proving useful in guiding several ongoing investigations. In a presentation to the Standing Committee on Public Accounts (Scopa), Mothibi confirmed that George Fivaz Forensics and Risk (GFFR) had been appointed by Business Leadership South Africa (BLSA) to conduct the probe in a contract facilitated by De Ruyter, who “was acting on his own”.

South Africa to co-host grid financing seminar with JSE in September

Electricity Minister Dr Kgosientsho Ramokgopa reports that he is planning to co-host a seminar with the JSE in September to unpack various financing options for the expansion of South Africa’s electricity grid. Insufficient investment in the transmission system over the past number of years has emerged as a key constraint to the integration of much-needed new generation capacity and is particularly acute in regions with high-calibre wind and solar resources such as the Eastern, Northern and Western Cape provinces.
