Risk 10 of 10 · Energy
Electricity, Energy and National Grid Failure
Insufficient or unreliable electricity and energy supply, deepening Eskom constraints and risk of national grid failure, threatening growth, jobs, safety and investment.
Definition
Insufficient or unreliable electricity and energy supply, deepening Eskom constraints and risk of national grid failure, threatening growth, jobs, safety and investment.
Opportunity
Diversify energy sources, accelerate renewable energy adoption, and enable decentralised energy solutions for resilience.
Why this risk matters
- Energy insecurity directly constrains growth, jobs, service delivery, safety and investor confidence.
- It increases costs across the economy and forces organisations to divert capital into self-protection and backup systems.
- Because energy underpins water, logistics, health, ICT and production, this risk has cascading system-wide effects.
Storyline
Southern Africa faces an enduring, system‑wide risk of electricity, energy and national grid failure as decades of under‑investment, maintenance backlogs and governance weaknesses in the power sector collide with growing demand and a slow transition to a more diversified energy mix. Historical neglect of generation, transmission and distribution assets at Eskom and municipal distributors has left an ageing, unreliable fleet with low availability and frequent breakdowns, while delays in adding new capacity and expanding the grid constrain the integration of renewables and new projects. Theft, vandalism and illegal connections, combined with financial strain and weak governance in parts of the energy value chain, further erode system resilience and increase technical and non‑technical losses.
These structural weaknesses manifest in recurring load‑shedding and localised power interruptions that reduce industrial output, shave growth off GDP, and damage equipment and productivity across sectors. Energy‑intensive industries are particularly exposed, and many firms have diverted capital into costly backup generation and embedded solutions, raising operating costs and, in some cases, prompting relocation of activity and new investment to jurisdictions with more reliable power. Households, small businesses, and essential services such as health, education, water, logistics, and ICT face repeated disruptions, safety risks and rising tariffs, with poorer communities least able to cope. Grid‑instability risks and the possibility of cascading failures remain a critical concern, even as short‑term performance improves.
Without sustained governance reform, accelerated investment in grid and generation infrastructure, and a faster but orderly shift to a more diversified, resilient energy system, electricity constraints will continue to act as a binding brake on growth, jobs, fiscal stability and social cohesion.

Southern Africa’s risk landscape is no longer a set of discrete “issues” to be managed in isolation, but a dense web of interconnected pressures that amplify one another across time. Governance failures weaken institutions’ capacity to manage infrastructure and service delivery, which, in turn, fuels social unrest, deters investment and deepens unemployment and inequality, further eroding trust in the state and the private sector. Climate shocks, water stress and energy constraints not only disrupt operations, but they also aggravate fiscal pressures, undermine public health and heighten security risks, feeding back into political instability and systemic corruption.
In this context, understanding the interconnectedness of risks is not a theoretical exercise but a practical necessity for leaders. It shapes which risks are truly systemic, where tipping points may lie, and which interventions can deliver reinforcing benefits across multiple domains. An interconnected view helps decision makers move beyond short-term, single-risk fixes towards integrated responses that build resilience in the whole system, i.e. institutions, communities, markets and the environment, rather than simply shifting vulnerabilities from one area to another.
Scenario outlook
| Time horizon | Best Case | Medium Case | Worst Case |
|---|---|---|---|
| Short-term (1-2 years) | Load shedding eliminated, Eskom reforms succeed, rapid deployment of renewable energy, grid stability restored, IPP capacity added. | Reduced but persistent load shedding, incremental improvements, ongoing Eskom challenges, slow renewable rollout, and business uncertainty. | Grid collapse, prolonged blackouts, industrial shutdowns, job losses, food spoilage, water system failures, and security breakdowns. |
| Medium-term (3-5 years) | Energy security achieved, diversified generation mix, smart grid operational, affordable electricity, and energy intensive industries thrive. | Adequate but expensive electricity, reliability concerns persist, slow transition to renewables, unequal access, and economic constraint. | Chronic energy crisis, deindustrialisation, permanent loss of energy intensive sectors, collapse, humanitarian emergency. |
| Long-term (6-10 years) | Clean energy leader in Africa, excess generation capacity, renewable energy exports, green hydrogen economy, and just transition completed. | Adequate supply but high costs, stranded coal assets, transition delays, missed opportunities, moderate progress. | Failed energy system, inability to rebuild, permanent electricity poverty, economic irrelevance, state failure. |

International view
Electricity, energy and national grid failure
Globally, energy security remains a significant concern, shaped by rising demand, infrastructure constraints, transition pressures, extreme weather and changing geopolitical conditions. These factors are driving increased organisational focus on energy resilience, backup capacity and alternative energy sources. Although not all organisations see energy disruption as a top immediate risk, major failures in electricity or national grid systems would have serious economic and operational consequences.
