A future project combining hydropower and solar energy: The Kakara power plant

The Kakara hydroelectric power plant project in Guinea represents a significant step in the country's quest to diversify its energy mix and meet the growing demand for electricity. This hydroelectric plant, situated on the Konkouré River, is designed to harness the country's hydraulic potential efficiently and sustainably.

The Kakara power plant, with a normal retention water level of 42 meters, demonstrates a commitment to environmentally friendly electricity production. With a nominal head height of 34 meters, the plant leverages advanced technology, equipped with two Kaplan axial turbo-alternators, each boasting an impressive capacity of 35 MW. These essential components operate at a unit nominal speed of 187.5 revolutions per minute, ensuring excellent electricity production efficiency.

The Kakara power plant project goes beyond energy production; it also aims to promote sustainable water resource management by maintaining a minimum operating level of 37 meters. This demonstrates a balanced approach between energy development and the preservation of the local ecosystem.

Moreover, the project involves robust transmission infrastructure, with a connection to the 225 kV coupling station in Boffa. This interconnection contributes to the efficient distribution of generated electricity, thereby enhancing the stability of Guinea's electrical grid.

In conclusion, the Kakara power plant project represents a crucial milestone in Guinea's energy strategy. By intelligently harnessing its hydraulic potential, the country demonstrates a commitment to a sustainable energy future. The Kakara power plant is more than just an electricity production facility; it embodies the vision of a harmonious and environmentally respectful energy development for Guinea.

Kakara

The Kakara Hybrid Hydro-Photovoltaic Project in Guinea is located downstream of the Fatala River, 143 km from the capital Conakry, 36 km from Boffa, and 10 km from the village of Lisso. The project consists of a hydroelectric power plant and a photovoltaic power plant, with a total installed capacity of 120 MW and a multi-annual average total electricity production of 394 GWh. Of this, the installed capacity of the hydroelectric power plant is 70 MW (35 MW x 2), with a multi-annual average of 4314 hours of production, and a multi-annual average production capacity of 302 GWh. The installed capacity of the photovoltaic power plant is 50 MW on the AC side. The first year of electricity on the grid is 99 GWh, with equivalent full-load hours of 1852.7 hours. The annual average electricity on the grid over 25 years is 92 GWh, with an annual equivalent of full-load hours being 1719.9 hours.

Photovoltaic power plant

The photovoltaic power plant is located on the left bank of the hydroelectric power plant, covering an area of approximately 0.8 km², with a planned installed capacity of 50 MW on the AC side. This project includes the construction of a 225/30 kV substation, whose main task is to step up the generated voltage. The first year of electricity on the grid is 99 GWh, with equivalent full-load hours of 1852.7 hours. The annual average electricity on the grid over 25 years is 92 GWh, with annual equivalent full-load hours of 1719.9 hours.
