Resilient Power Systems: Addressing Electricity Reliability Challenges

Energy analyst Dr. Elikplim Kwabla Apetorgbor has called on Ghana and other developing economies to shift their energy planning focus from increasing generation capacity to strengthening the resilience and security of the entire electricity architecture.

In a detailed policy analysis, Apetorgbor argued that sufficient installed generation capacity does not guarantee a reliable power supply if the broader system remains vulnerable. He noted that countries can possess adequate megawatts on paper yet still suffer from recurring outages due to weak transmission networks, unstable fuel systems, and exposed control systems.

Reliable electricity supply is no longer only a question of generation capacity.

According to the analysis, many governments maintain a narrow strategy focused on adding generation. Apetorgbor asserted that this approach is insufficient if transmission systems cannot evacuate power, distribution networks are overloaded, or utilities continue to operate with outdated systems.

Defining Power System Security

Apetorgbor’s framework expands the definition of power system security beyond engineering reserves and transmission maintenance. He identified several critical pillars necessary for a resilient system:

• Cybersecurity and physical infrastructure protection
• Operational coordination and automation
• Fuel sustainability and strategic reserves
• Financial health and institutional discipline
• Emergency preparedness

The analyst highlighted that the digitalization of power networks has created cyber-physical systems. While technologies such as smart meters, SCADA, digital substations, and cloud platforms improve efficiency, they also increase vulnerability to cyber threats. Apetorgbor urged that cybersecurity be treated as a core component of national energy security, supported by mandatory standards, regular audits, and dedicated operational technology security centers.

Infrastructure and Automation

The policy paper emphasizes the protection of physical assets—including transformers, transmission towers, fuel pipelines, and control centers—as strategic national infrastructure. Apetorgbor warned that disruptions to these assets can directly impact critical services such as banks, hospitals, schools, and telecommunications.

Grid Automation Is the Backbone of Resilience.

He argued that automation technologies are essential for operational intelligence. Specifically, he pointed to advanced metering infrastructure, fault isolation systems, SCADA upgrades, and distribution management systems as critical tools for faster fault detection and quicker power restoration.

Fuel Security and Strategy Shift

Fuel supply was identified as a primary pillar of reliability, particularly for thermal-dependent systems. Apetorgbor noted that disruptions in gas or liquid fuel supplies can idle generation plants and destabilize the broader grid.

To mitigate these risks, he called for the implementation of formal fuel security frameworks. These would include emergency financing protocols, transparent allocation systems, dual-fuel capabilities, and the establishment of strategic reserves.

The priority must now shift from a narrow ‘more megawatts’ strategy to a broader secure, intelligent, flexible, and resilient power system strategy.
