It is estimated that the renewable energy IPPs round will likely deliver prices below 50c per kilowatt hour, which is way below the cost of running many of Eskom's coal power stations. This means that these and future IPPs are likely to contribute to lower electricity prices for consumers, which will benefit the poor in the main and encourage economic growth. The renewable energy IPPs have assisted Eskom in improving security of supply without putting a drain on its balance sheet or cash flows, because as they have been generating power, Eskom did not have to invest in setting up those generation facilities.
