Energy expert rules out sabotage at ECG by staff as PURC begins investigation into ECG network challenges. Energy Expert, Kojo Poku has disputed rumours that some workers of ECG are sabotaging the system making it difficult for consumers to purchase credit for their prepaid meters. For the past four days consumers using these meters have challenges purchasing credit. The ECG said the challenge is as a result of network problems. In an interview with Radio Ghana, Mr. Kojo Poku said it will be strange for any worker at the ECG to sabotage the system as a result of the concession plan for ECG as agreed in the Millennium Challenge Compact two.
