In the control room of the hydroelectric dam in Kpong in eastern Ghana, the engineers are regulating the spillway gates on computer screens. This a huge change because all these maneuvers were still being done manually before the facilities were rehabilitated. rehabilitation of these facilities.
Located in Akuse, this 160 MW dam is one of two facilities that generate 30% of Ghana’s national electricity. It is owned and operated by the Volta River Authority (VRA), the long-standing public utility for Ghana’s electricity production. Commissioned in 1982, this hydropower plant operated reliably until the early 2000s, after which, power outages caused by the outdated equipment have since become increasingly frequent.
To address this problem, the government has called on independent power producers, most of which supply thermal energy, which often tends to pollute. Supported by Agence Française de Développement (AFD), the rehabilitation of the dam was necessary to supply more stable and cleaner energy in Ghana. Following this rehabilitation, consumers now benefit from an improved and reliable electricity supply. Another significant improvement is that the dam operators can now diagnose problems faster.
One of the main objectives of the Kpong Dam rehabilitation program is “to secure Ghana’s hydropower supply”, says Camille Le Thuc, project team manager at AFD’s Energy Division. “This has long been a concern in this country, the first in the region to build a 1,000 MW dam in the 1960s.”
The other major aim concerns the production of clean energy. An energy in line with the government’s targets. It adopted a law on renewable energies in 2011 with the objective of increasing domestic production. With these new facilities, the Kpong Dam is helping realize this objective by reducing greenhouse gas emissions.
However, the development of renewable energies (REN), such as solar and wind energy, is still in its infancy and they account for less than 1% of the mix. “The plant is more reliable thanks to the state-of-the-art technology. It will be able to operate at full capacity and generate carbon-free electricity to supply the domestic grid”, says Johnson Hlodzie, Director of the power plant. Some 400,000 tons of CO2 are avoided yearly.
With its capacity, the Kpong Dam is bringing an additional 160 MW of renewable energy to the national energy mix. In addition to the electricity production, the dam is also providing irrigation water for agriculture and supplying several municipalities.
This 100% renewable energy power plant has also put the country on a virtuous path towards achieving its sustainable development goals. In addition to this, the realization of this project is a strong symbol of the renewed partnership between France and Ghana.
