Eskom’s Revival: Shifting Focus from EAF to Plant Health

Report Advocates Overhaul for Sustainable Power in South Africa

by Adenike Adeodun

In an exhaustive analysis conducted from March to May 2023, a Vgbe-led consortium, on behalf of the National Treasury, scrutinized the operational state of Eskom’s 14 coal-fired power stations. This report elucidates a critical shift in perspective regarding the management and maintenance of these facilities, challenging the current operational ethos that prioritizes the energy availability factor (EAF) above all. The findings of this assessment shed light on the systemic issues plaguing South Africa’s primary electricity supplier, suggesting a recalibration of strategies to avert further deterioration of the national power grid.

The core issue identified is the prevailing “fixation” on maintaining a high EAF, which has inadvertently led to a decline in the overall health of the power plants. In efforts to sustain or elevate the EAF, maintenance and outage activities have been consistently postponed, compromising the technical condition of the plants for short-term gains. This approach has culminated in an alarming increase in incidents, trips, and partial load losses, potentially precipitating a catastrophic failure of the power stations if left unchecked.

Remarkably, the report indicates that despite Eskom’s substantial maintenance budgets, the coal fleet’s EAF hovers around 51%, significantly trailing the global standard of 78%. This discrepancy underscores a profound inefficiency and mismanagement within the system. The consultants argue for a strategic pivot towards conducting thorough maintenance and repair work, advocating for a temporary increase in load shedding as a necessary trade-off for long-term stability and efficiency gains. They estimate that up to 6,000 MW of capacity could be recuperated by rectifying existing defects and adhering to sound operational and maintenance practices.

This assessment arrives amid Eskom’s ongoing attempts to revitalize its Generation Recovery Plan, which ambitiously aims to elevate the EAF to 65% by the end of March and 70% by March 31, 2025. However, the report’s recommendations seemingly diverge from Eskom’s current trajectory, proposing a more radical overhaul of maintenance strategies and management philosophies.

The National Treasury has acknowledged the report’s implications, indicating that select insights will be integrated into Eskom’s 2024/25 Corporate Plan, though specifics remain under wraps. The analysis was commissioned in the context of the National Treasury’s R254-billion debt-relief package to Eskom, aiming to diagnose and remedy the inefficiencies crippling the coal fleet.

Attributing the low EAF to a “dysfunctional” management structure within Eskom Generation, the report advocates for a significant reorganization. It suggests decentralizing decision-making and granting power station managers full budgetary control and accountability. This entails a restructuring of the Generation Division’s management, proposing the segregation of the coal fleet to focus exclusively on its revival.

This proposed paradigm shift in governance and operational strategy coincides with the appointment of Dan Marokane as the new CEO of Eskom. Marokane’s mandate, as directed by the board, includes a comprehensive review of the Generation Operational Recovery Plan and the unbundling plans, in addition to fostering engagements with a broad spectrum of stakeholders. His leadership arrives at a pivotal moment for Eskom, as it navigates through the intricacies of operational inefficiencies, financial burdens, and the urgent need for systemic reform.

The report posits a forward-looking vision for Eskom, emphasizing the imperative of transitioning from reactive fixes to a strategic, holistic approach to maintenance and management. By realigning operational priorities and restructuring governance, there is a pathway to not only stabilizing Eskom’s coal fleet but also setting a precedent for sustainable, efficient energy production in South Africa. This comprehensive assessment not only diagnoses the current malaise afflicting Eskom but also charts a course for its recovery and future resilience, marking a critical juncture in the nation’s quest for reliable and sustainable energy.
