The Africa Sustainable Energy Centre (ASEC) has called for significant reforms in Ghana's electricity transmission infrastructure. This demand follows an investigative report into the recent fire at the Akosombo Substation. The incident, attributed to ageing infrastructure and insulation failure, exposed major weaknesses in the national power system.
The fire at the critical Akosombo Substation was not sabotage. Investigators linked it to 'pure engineering and structural failure'. This incident revealed that a single point of failure could threaten national power stability. Such an event risks disrupting economic activities and public services across Ghana.
This incident fits a trend of infrastructure challenges impacting Ghana's energy sector. Historically, issues like 'dumsor' (power outages) have stemmed from generation, transmission, or distribution problems. Modernising key infrastructure, like the Akosombo Substation, is crucial for Ghana's economic stability and growth. Reliable power is essential for businesses and daily life.
ASEC's Executive Director, Ing. Justice Ohene-Akoto, emphasised the need for stronger maintenance practices. He also called for improved fire protection systems and enhanced power network reliability. ASEC specifically recommends regular Infrared (IR) thermographic inspections at key substations. This technology can detect equipment issues before they cause major failures, preventing costly repairs and outages.
The findings point to possible weaknesses in protection coordination and Short Circuit Coordination Studies (SCCS). ASEC expressed concern that one transformer continued to supply power to a fault after another tripped. This highlights a need for a comprehensive review of protection philosophies across the national transmission network.
ASEC further advocated for modern fire detection and automatic suppression systems. They argue that critical facilities should detect and suppress fires within seconds. This minimises equipment damage and service disruptions effectively.
The organisation also stressed the importance of stronger redundancy measures. Redundancy means having backup systems to prevent localised faults from becoming national emergencies. This includes backup communication networks and alternative control centres to maintain system stability during crises.
Ghana's energy sector must move away from reactive maintenance. ASEC suggests adopting predictive maintenance powered by technologies such as artificial intelligence and condition monitoring. These tools can identify potential failures before they lead to service interruptions or major equipment losses.
The successful restoration of electricity supply by engineers after the Akosombo incident was commendable. However, ASEC insists this experience must lead to a modernisation of operations. The reforms aim to build a safer, more resilient, and future-ready power sector in Ghana.
This push for reform highlights a critical juncture for Ghana’s energy future. Decision-makers and market participants will be closely watching the Ministry of Energy and Green Transition's response. Implementing these recommendations could significantly improve grid reliability, reduce power outages, and support Ghana's long-term economic development. Lack of action could leave the nation vulnerable to further infrastructure failures.
