a) Based on assumptions made in the IRP, the combined effect of including coal and Inga as policy adjustment is about 1.9 cents per kilowatt hour on projected tariff of 119 cents per kilowatt hour.
b) The decision taken to deviate from the least cost scenario by including the Inga hydropower into the IRP was on the basis that there is a treaty signed between the government of South Africa and the Democratic Republic of Congo for South Africa to off take 2500MW from the project.
c) The IRP assumes the project to come online by year 2030.
