Kumasi power grid upgrade nears completion as GRIDCo's transmission line reaches 70% done

Ghana's electricity transmission operator GRIDCo is making substantial progress on a critical infrastructure upgrade that promises to enhance power supply stability across Kumasi and surrounding areas. The Anwomaso–Ahodwo transmission line project has reached 70% completion, with the company announcing planned outages in November to finalise the commissioning phase of this vital project.

The upgrade represents a significant investment in Kumasi's electrical infrastructure, addressing long-standing challenges with power distribution reliability in Ghana's second-largest city. The transmission line connects two strategic distribution points—Anwomaso and Ahodwo—to create a more robust network capable of handling the region's growing electricity demand.

Timeline and planned disruptions

GRIDCo's official announcement on October 29 confirmed that scheduled power outages will be necessary in November to complete final commissioning activities. While the exact duration and specific dates of these outages were not detailed in the statement, consumers and businesses in the affected areas have been advised to prepare accordingly. Such planned interruptions are standard practice in grid modernisation projects, allowing engineers to test new infrastructure and integrate it safely into the existing system.

The phased approach to completion reflects the technical complexity of transmission line upgrades, which require meticulous testing to ensure safety and operational stability before full integration into the national grid.

Why it matters for Ghana

Kumasi's power reliability has been a persistent challenge affecting both residents and businesses in the metropolis. Manufacturing firms, educational institutions, and healthcare facilities depend on stable electricity supply, and transmission bottlenecks have historically caused frequent outages. This upgrade directly addresses those vulnerabilities by creating alternative pathways for power distribution and increasing the system's capacity to manage peak demand periods.

For Ghana's broader development agenda, the project exemplifies the need for continued investment in electricity infrastructure modernisation. The country's power sector has faced growing pressure from rising demand driven by urbanisation and industrial expansion, particularly in major cities like Kumasi. Improvements to transmission infrastructure not only reduce outages but also minimise technical losses in the distribution network—losses that ultimately inflate electricity costs for consumers.

GRIDCo's systematic approach to infrastructure development also signals confidence in Ghana's ability to maintain reliable power supply as the economy grows. Stable electricity is fundamental to attracting and retaining investment, supporting job creation, and improving living standards across the region.

Looking ahead

Once completed, the Anwomaso–Ahodwo line will join other recent transmission upgrades as part of GRIDCo's ongoing modernisation programme. The company manages Ghana's high-voltage transmission network, which forms the backbone connecting power generation sources to regional distribution companies that serve individual customers.

Kumasi residents and businesses should monitor GRIDCo's announcements for specific details about November outage schedules. Stakeholders are advised to make appropriate contingency plans, particularly those operating critical services dependent on continuous power supply.
