Kenya: National Cement is set to build a 15MW coal-fired power plant in Kajiado at a cost of US$19m as part of its expansion plan. The plant will feed its upcoming limestone mining and clinker manufacturing operation in the same location.

National Cement will transport the clinker to its plant in Lukenya, which is being expanded to 1.7Mt/yr capacity from the current 600,000t/yr. National Cement, which produces the Simba cement brand, said that it decided to generate its own electricity because of delays in connecting to the national grid, where power is also more expensive. "The cost of procuring electricity from Kenya Power is twice as much when compared with the cost of generating power using coal," said National Cement.

Electricity supplied from the national grid currently costs an average of US$0.18/kWh. Based on current international coal prices, power generated from coal costs US$0.15/kWh. Coal prices have dropped by 18% since the start of 2014 and a further fall could make energy derived from coal even cheaper. However, the Kenyan government has said that the cost of power form the national grid could halve in the medium term on expansion of the country's generation capacity to 5000MW from the current 1300MW.

Besides seeking lower costs, National Cement has said that it has been forced to construct the coal plant due to Kenya Power's delays in connecting its Kajiado operations. "Kenya Power is also unable to provide power to National Cement within the required time frame (within two years) and only install the electricity in three years' time, while electricity is needed for the clinker manufacture in 24 months' time."

National Cement states that it will import coal from countries like South Africa, but Kenya's move to start mining its own coal could see the firm source the commodity locally in the future. The coal consumption for the proposed power plant is estimated at 63,360t/yr. Saving on energy costs is expected to boost the firm's margins, underlining the importance of lower operational costs in an industry hit by vicious price wars.
