Pre-Feasibility Study for the GDE Gas-Fired Power Plant Project in Conakry

Sub-Saharan Africa

October 24, 2022

K&M was contracted by Guinéenne d’Energie (GDE) to perform a pre-feasibility study for a new gas-fired power plant project in Conakry. The objective of this assignment is to identify the size and timing of gas-fired capacity additions that are economically justified in the Guinean grid, estimate the economically justified electricity generation using natural gas and resulting gas demand, assess the viable generation options for a new gas-fired power plant in Conakry, and develop an implementation plan for progressing the project from its current conceptual stage to a commissioning stage.

K&M’s scope of work included:

K&M has commenced this pre-feasibility study by collecting data on the current state of the power system in Guinea and developing a simplified model to estimate thermal capacity requirements to meet annual peak and reserve requirements. From this work, K&M has identified the size and timing of gas-fired capacity additions that are economically justified in the Guinean grid. K&M also developed a simplified merit-order dispatch model to estimate the dispatch of a new gas-fired power plant and calculate the resulting gas demand. Later, the team assessed viable interconnection arrangements between the power plant and transmission system substation, evaluated site conditions, and identified viable technologies and configurations. K&M also calculated and compared the marginal costs and the Levelized cost of electricity for each generation technology option. Lastly, the team assisted the project by developing an implementation plan to help progress the project from the current conceptual stage to the commissioning stage.
