He said the recent power outages is 'dumsor' and any attempts by the government to whitewash it won't hold.
Mr. Nketia, who is popularly known as General Mosquito, said it is high time the government told Ghanaians the truth.
Speaking on Accra based Joy News, he said: "Dumsor has come and this one is because of the negligence of this government".
“If they are building new transmission lines, it has nothing to do with the existing transmission lines… so how does your building of a substations somewhere contribute to dumsor? It is after you have finished the new line or substation and you want to change over. And that will take you more than a week to do."
“So what is happening now is the breakdown of the existing systems when the new ones haven’t happened yet", he said.
However, in earlier engagements, the Minister of Energy, Dr. Matthew Opoku Prempeh had denied that dumsor is back.
The Minister said what was happening had nothing to do with financial challenges as being speculated but rather purely technical.
Speaking on a working visit to the Ghana Grid Company (GRIDCO) in Accra, he said: “These our lines that we have just been informed about, were strung in the 50s and some in the 60s. The power it was supposed to transmit to Accra has increased tremendously due to the expansion of Accra yet the lines have remained the same. They are now giving us lines that can improve the power situation in Accra”.
Dr Prempeh said what was required now was the foreberance of the Ghanaian because what was being planned and implemented would better improve the situation for all.
