The Institute for Energy Security, IES, has urged the government and the Ghana Grid Company Limited, GRIDCo, to make public the findings of the technical investigation into the nationwide electricity blackout recorded on July 29, 2026.
The call has gained renewed significance following another widespread power disruption that affected several parts of Ghana during the early hours of Thursday, August 20. GRIDCo has attributed the latest incident to a major fault on the Akosombo and Volta transmission line, which triggered the automatic shutdown of generating units at the Akosombo Power Station as well as some thermal generating plants.
Speaking on JoyNews’ The Pulse on Thursday, August 20, the Senior Research and Policy Analyst at the IES, Derrick Xatse, maintained that the publication of the July 29 investigation report was necessary to help the public understand the circumstances that precipitated the earlier national blackout and the corrective interventions introduced since then.
The July 29 disruption occurred after the National Interconnected Transmission System experienced a major disturbance at approximately 3:11 a.m. According to GRIDCo, several generating plants tripped simultaneously, resulting in widespread interruptions to electricity supply. The company subsequently announced that a comprehensive technical inquiry had been initiated to establish the precise cause of the disturbance and guide appropriate remedial measures.
Mr Xatse, however, expressed concern that almost three weeks after the incident, the outcome of the investigation had yet to be made available to the public.
He said the IES had not seen the report and questioned whether it had been released to the media or other stakeholders.
The energy analyst argued that the recurrence of a nationwide power disruption before the conclusions of the previous investigation had been disclosed raises important questions about the robustness and reliability of Ghana’s electricity transmission infrastructure.
Thursday’s latest outage was linked by GRIDCo to a significant technical fault along the Akosombo and Volta transmission corridor. The company explained that the protective mechanisms within the national power network automatically disconnected the Akosombo generating units and some thermal plants in order to safeguard the stability and integrity of the National Interconnected Transmission System. Restoration operations were subsequently initiated, with GRIDCo reporting that power had been restored to some affected areas while technical teams continued efforts to reconnect remaining customers.
Against this backdrop, Mr Xatse has called on the government to publish the July 29 technical assessment if it has been completed and to provide Ghanaians with a clear account of the vulnerabilities identified during the investigation.
He further urged the authorities to disclose the specific interventions being implemented to address weaknesses within the national electricity network and reduce the possibility of another widespread system failure.
The IES has also appealed to the Ministry of Energy and Green Transition and GRIDCo to provide greater clarity on the additional safeguards being introduced under the temporary arrangements currently being used to sustain electricity supply. According to the institute, such measures must be carefully managed to ensure that efforts to maintain power availability do not inadvertently create additional vulnerabilities within the national grid.
The latest developments have intensified scrutiny of Ghana’s electricity transmission system, particularly as concerns persist over the capacity of existing infrastructure to withstand major technical disturbances. Recent analysis from the IES has similarly pointed to pressure on transmission infrastructure, with Mr Xatse arguing that growing electricity demand and inadequate investment in transmission capacity could increase stress on ageing lines and substations.
For the IES, the issue extends beyond the immediate restoration of electricity after an outage because dependable power supply remains fundamental to household activity, commercial operations and industrial productivity.
Mr Xatse therefore stressed the importance of transparency, timely disclosure and decisive technical intervention, insisting that Ghanaians deserve to know what caused the July 29 blackout, what lessons were derived from the investigation and what concrete measures are being deployed to prevent a repetition.
The institute believes that releasing the investigation report would not only provide accountability over the earlier disruption but would also help the public assess whether adequate safeguards are being established to strengthen the resilience of the national power system following yet another major outage.
