GRIDCo Announces 15-Hour Power Outage in Parts of Accra as Emergency Tower Works Continue

The Ghana Grid Company Limited (GRIDCo) has announced a planned 15-hour outage on the V19HV and V24H transmission lines on Sunday, August 23, 2026, to allow engineers to continue emergency tower replacement works on the 161kV Volta–Achimota transmission line.

The notice was contained in a letter dated August 21, 2026, addressed to the Managing Director of the Electricity Company of Ghana (ECG).

According to GRIDCo, the emergency works involve the replacement of transmission tower T.09(01/02), located on the Ashaiman section of the Volta–Achimota 161kV transmission line.

GRIDCo explained that the tower replacement works were not fully completed during the earlier exercise conducted on Sunday, August 16, 2026.

The company said additional work is therefore required to complete the project and ensure the safe and reliable operation of the transmission line.

“As planned,” the company stated, the tower replacement works will continue on Sunday, August 23, 2026, during which an outage on the V19HV and V24H lines will be granted from 3:00 a.m. to 6:00 p.m.

The scheduled duration is 15 hours, covering the period from 3:00 a.m. until 6:00 p.m. on Sunday.

GRIDCo has consequently requested the Electricity Company of Ghana to make the necessary load-management arrangements to facilitate the execution of the emergency works.

The affected areas listed in GRIDCo’s work schedule include Nima Township, Kanda Highway, Kanda Estate, Sulana, Kokomlemle, Circle, Madina Township, Okponglo, Cantonment, Osu Oxford Street, James Town, Mamprobi and Chorkor.

Other affected locations are Sempe, parts of Kaneshie, the North Industrial Area, Okaishie, Adauome, Agbogbloshie, Kantamanto, Adabraka, parts of Ridge, Tesano, Santanna Market, parts of Alajo, Malam Atta Market, Asylum Down, Labone, Kojo Sardine and Teshie Rasta Road.

The information forms part of GRIDCo’s emergency work schedule for the 161kV Volta–Achimota transmission lines, with the affected areas listed under the first day of the emergency works.

The transmission company stressed that the continuation of the work is necessary because the replacement exercise could not be fully completed during the previous outage period.

The letter was signed by GRIDCo Chief Executive, Ing. Frank A. Ochtere, and copied to the Minister of Energy and Green Transition.

GRIDCo, which describes itself as the “Backbone to Power Delivery,” said the additional work is intended to support the safe and reliable operation of the transmission network.

Residents and businesses within the listed areas are therefore expected to make appropriate arrangements for the scheduled outage on Sunday, August 23, while ECG undertakes the required load-management measures during the 15-hour maintenance window.

The exercise is part of ongoing emergency interventions on the transmission infrastructure to address the affected tower and complete the replacement works on the Ashaiman section of the Volta–Achimota 161kV transmission line.
