TL;DR
Africa’s energy transition faces a major obstacle: ‘Zombie Energy Systems’—obsolete, inefficient infrastructure that persists despite being outdated. Addressing these systems is crucial for achieving sustainable development and climate goals.
Recent studies and expert analyses confirm that obsolete and inefficient energy systems—termed ‘Zombie Energy Systems’ (ZES)—persist across Africa, obstructing the continent’s efforts to modernize its energy infrastructure and meet sustainable development goals. These systems, rooted in colonial legacies and economic constraints, continue to operate despite being environmentally harmful and economically unviable, posing a significant barrier to Africa’s energy transition.
Experts emphasize that ZES include aging coal and gas power plants, outdated hydroelectric dams, diesel generators, and poorly maintained transmission networks on the supply side. On the demand side, they encompass inefficient household appliances, obsolete boilers, and old vehicles. According to energy analysts, these assets often require high maintenance costs and contribute disproportionately to environmental pollution, yet they remain operational due to regulatory gaps, lack of investment, and institutional inertia.
International agencies and regional policymakers recognize ZES as a critical challenge. A recent report from the African Development Bank notes that these outdated systems undermine efforts to expand clean energy access, especially amid rapid population growth and urbanization. While some countries have begun decommissioning certain assets, comprehensive strategies to systematically replace or upgrade ZES are still lacking.
Impacts of Persistent Outdated Energy Infrastructure
The continued operation of ZES hampers Africa’s ability to meet climate commitments and achieve universal electricity access. These systems contribute to high greenhouse gas emissions, environmental degradation, and inflated operational costs, which divert investments from renewable energy projects. For citizens, this means ongoing energy poverty and limited economic opportunities, especially in rural areas. Addressing ZES is therefore essential for the continent’s sustainable development and climate resilience.

Origins and Challenges of ‘Zombie’ Energy Assets in Africa
The phenomenon of ZES in Africa is rooted in colonial-era infrastructure, combined with decades of underinvestment, policy neglect, and financial constraints. Many outdated power plants and grids were built in the mid-20th century and have since become obsolete, yet they remain operational due to a lack of decommissioning policies and the high costs associated with replacement. Recent efforts to upgrade energy systems have often focused on new infrastructure, leaving existing inefficient assets unaddressed. The COVID-19 pandemic and global economic challenges have further delayed modernization efforts, allowing ZES to persist.

Unclear Scope and Strategies for ZES Decommissioning
While experts agree that ZES are a major barrier, detailed data on the exact number and condition of these assets across different countries remains limited. There is also no unified regional strategy for their systematic decommissioning or upgrading, and funding mechanisms are still under development. It is unclear how quickly and effectively African nations can implement comprehensive reforms to eliminate these outdated systems.

Next Steps Toward Modernizing Africa’s Energy Infrastructure
Efforts are underway to develop integrated policies that promote the phased decommissioning of ZES, coupled with investments in renewable energy and grid modernization. International donors, regional bodies, and national governments are increasingly recognizing the need for tailored solutions, capacity building, and regulatory reforms. The upcoming African Energy Forum is expected to feature discussions on strategies to accelerate these reforms and mobilize funding for large-scale upgrades.

Key Questions
What exactly are ‘Zombie Energy Systems’?
They are outdated, inefficient, and often environmentally harmful energy assets that continue to operate despite being obsolete, including old power plants, grids, and appliances.
Why are ZES still operating in Africa?
Due to high costs of decommissioning, lack of regulatory frameworks, limited investment, and institutional inertia, many ZES remain functional despite their inefficiency and environmental impact.
How do ZES affect Africa’s climate goals?
They contribute to higher greenhouse gas emissions and environmental degradation, undermining efforts to meet climate commitments and transition to renewable energy sources.
What can be done to eliminate ZES?
Comprehensive strategies include regulatory reforms, targeted investments in modern infrastructure, capacity building, and phased decommissioning plans tailored to each country’s context.
Who is responsible for addressing ZES?
National governments, regional bodies, international development agencies, and private investors all have roles in developing policies, funding, and implementing upgrades or decommissioning outdated systems.
