COEGA Industrial Development Zone, Port Elizabeth, Eastern Cape Coega is IPSA’s largest development project to date. Originally planned as a CCGT project of 800 MW, it was increased in size at the request of the DME to become a project of 1,600 MW in two separate blocks of 800 MW each. IPSA has acquired 500 MW of Siemens Westinghouse Avio gas turbines for the project. A further 500 MW of gas turbines are being reserved to form the open cycle components of the twin block project. Initially each block will operate using only the 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. IPSA expects to be able to bring its open cycle units on line at Coega within nine months of receiving planning consents and regulatory approvals, subject to the necessary environmental consents which are expected to take around six months to obtain and also subject to financing being completed. 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. |
