IPSA is continuing discussions with a view to develop a CCGT project of 1,600 MW in two separate blocks of 800 MW each. Initially each block will operate using only gas turbines with conversion to combined cycle, using the similar waste heat recovery systems as have been installed at Newcastle, taking place at a later stage. Open cycle gas turbines can be commissioned relatively quickly and IPSA expects to be able to bring its open cycle units on line at Coega within nine months. This is subject to receiving planning and environmental consents, regulatory approvals, and financing; which is expected to take a total of around six months.
This fifteen month construction timetable is less than half the time that it takes to build a modern coal-fired plant. It is intended that the full 1,600 MW Coega plant will eventually run on liquefied natural gas (LNG) imported into what will be one of only two LNG receiving terminals currently planned for South Africa. In the short term, however, the initial 1,000 MW of open cycle capacity is expected to operate using liquid fuels.
