The power generation units of the Bui Dam are being increased to augment the country’s power supply, under a mini power project.
Four megawatts of additional power would be generated to bring the installed capacity of the bui dam to 404 megawatts.
The Bui Dam as at Thursday generate between 80-220 megawatts of power at peak period (between 4.30 a.m. to 12pm) below the installed capacity, partly due to its 170.01-metre level of water metres above sea level, a little more than two feet above the minimum operating level of 168 metres.
The Deputy Project Manager of Sinohydro Corporation Limited, Zhang Yang, who disclosed this to journalists on a tour of the dam, here on Thursday, said the project, which started in September, last year, was scheduled to be completed in December this year.
The tour, organised by the Chinese Embassy in Accra to highlight the Chinese Government’s investments in Ghana, formed part of the activities marking the 55th anniversary of the diplomatic relations between China and Ghana.
Mr Zhang said, the new power generation unit was being constructed in the diversion channel created for the Black Volta, when the Bui Dam was being constructed.
The construction of the Bui Dam by a Chinese Company, Sinohydro Company Limited, was started in August 2007, and completed in December 2013, and handed over to government in November 2014.
The $790 million project was mainly financed by the Chinese Government, and located in Bui between Banda and Bole districts in Brong Ahafo and the Northern regions respectively.
Mr Zhang declined to reveal the cost of the project, but said it was imputed in the total cost of the Bui Dam.
He said, the company constructed two saddles to protect the dam and prevent the river from diverting it course, adding that the dam had four extension lines to transmit power to Sunyani, Sawla, Techiman and Wa.
Mr Zhang said the dam had a 50-year lifespan and was confident that with proper maintenance, it could last that much.
A source at the Bui generation station of the Bui Power Authority (BPA) speaking on condition of anonymity, said the new power plant was being created to provide power to the offices of Bui Power Authority in Bui and its adjoining communities.
“The new generation units will serve as backup to start the three major power generation units when they are shut down for routine maintenance,” he said.
At the moment, the source said, the BPA had to buy power to start the three generating units if they were shut down for maintenance.
