Kumasi’s Power Boost: Final Phase of Transmission Upgrade Begins July 20
Kumasi is about to get a major power upgrade. Starting July 20, 2026, the Ministry of Energy and Green Transition, GRIDCo, and ECG will begin the final phase of the Kumasi-Anwomaso Transmission Line Upgrade and transformer replacement at the Kumasi (Ahodwo) Substation. This is great news for businesses, residents, and investors in the Ashanti Region, because it means a stronger, more reliable electricity network that can support our growing economy.
Yes, there will be some temporary power outages during the work. But think of it this way: a few short-term inconveniences for long-term gains. The government is investing in infrastructure that will double the transmission capacity and make sure Kumasi doesn’t get left behind as it booms.
Why This Upgrade Matters for Business and Innovation
Kumasi has been relying on an aging 19-kilometre single-circuit transmission line that simply can’t keep up with the city’s rapid growth. The current line has a capacity of 364MVA, but it’s overloaded. The new double-circuit line will handle 2 × 488MVA (978MVA), more than doubling the capacity. That means more power for new factories, tech hubs, and commercial centers.
According to the joint statement from the Ministry, GRIDCo, and ECG, the upgrade will “significantly enhance the reliability, resilience and efficiency of electricity supply to Kumasi and the wider Ashanti Region, while creating additional capacity to support future residential, commercial and industrial growth.” This is exactly the kind of forward-thinking infrastructure that attracts investment and fuels entrepreneurship.
Progress So Far: 90% Foundation Works, 67% Tower Assembly
The project is already well advanced. As of July 16, 2026, about 90% of foundation works and 67% of tower assembly were completed. The final stage involves dismantling the old line, erecting new towers, and stringing new conductors. The work is expected to be finished within three months.
In addition, GRIDCo will replace one of the existing 66MVA transformers at the Kumasi (Ahodwo) Substation with a new 145MVA transformer. This will boost transmission capacity, improve operational flexibility, and reduce strain on existing equipment. It’s a smart, data-driven move to ensure power reliability for years to come.
What This Means for the Diaspora and Investors
For Ghanaians abroad looking to invest back home, this is a clear signal that the government is serious about creating a business-friendly environment. Reliable power is the backbone of any modern economy. With this upgrade, Kumasi is positioning itself as a hub for manufacturing, technology, and services. The Ashanti Region is open for business, and the power grid is ready to support it.
The Ministry has also assured that GRIDCo and ECG will issue advance notices before each planned outage, and every effort will be made to restore power before the evening peak. Safety remains the top priority, with residents urged to stay clear of construction areas.
Frequently Asked Questions
Will there be power outages during the upgrade?
Yes, there will be temporary and localized power interruptions for customers served by the Kumasi (K1) and Anwomaso (K2) substations. But advance notices will be given, and power will be restored before the evening peak whenever possible.
How long will the final phase take?
The final phase is expected to be completed within three months, starting July 20, 2026.
How much will the new transmission line increase capacity?
The new double-circuit line will have a capacity of 978MVA, more than double the current 364MVA. This will support future residential, commercial, and industrial growth.
The Ministry acknowledged that the temporary interruptions may inconvenience residents and businesses, but stressed that these upgrades are necessary to deliver “a stronger, more reliable and higher-capacity electricity network that will support the long-term development of Kumasi, the Ashanti Region and Ghana.” I couldn’t agree more. This is the kind of bold, data-driven investment that moves Ghana forward.
