Electricity consumers in Ghana may have to brace themselves for more power cuts as authorities of Ghana’s biggest power producer, the Volta River Authority (VRA), plan shutting down two more turbines of the Akosombo Hydroelectric Dam.

The country’s biggest power-generating plant has run on four of its five turbines over the past months, contributing 632 megawatts (MW) to the national grid, local media reported here Friday.

A continuing drop in water levels in the dam over the past month has compelled the authorities to shut down two more turbines.

The minimum operation level of the dam is 240 feet but it has been operating below that level since June, this year.

Local television network, TV 3 said as at Thursday when it visited the dam site, the water level was 237.88ft.
“We have delayed in bringing the generators down,” observed Ebo Amoah, an electrical engineer at Akosombo.
“This one you need authorization to do that. We have written to [government] and we are hoping that they will implement it.”

He said the situation could worsen in the coming days if the water levels went below 235ft.
“If you go below the 235, you will collapse the reservoir and for you to recover it, it will take a long time,” the network quoted Amoah as saying.

Last month, the VRA announced it was planning to reduce the operating capacity of the Akosombo Dam due to a drop in water level, which stood at 238.57 ft as at June 26, almost two feet below the minimum operating level of 240ft.
According to authorities of the VRA, the last time the Dam recorded such a similar level was on June 22, 1984 when levels dropped to 235.76ft.

The hydroelectric dam has six turbines with a capacity of 1020 megawatts (MW) but has been operating on four and, sometimes, three turbines. Enditem
