27 June 2013 – Eskom says that the first unit of the 4,764 MW Medupi power station should be commissioned by December 2013 with the last Medupi unit to be commissioned in 2016. In June 2013 up to 116,000 tonnes of coal was already on site in preparation for the first firing of the boiler.
The utility says the final Unit 6 turbine coupling installation is already in progress at Medupi, coal stockpiles, ash stockpiles and all related equipment are close to commissioning, and the water treatment plant is close to completion. It also says the transmission high-voltage yard is complete for five units, and infrastructure to access transmission lines is advanced.
The 1,332 MW Ingula pumped storage scheme, located 23 km northeast of Van Reenen, within the Little Drakensberg mountain range on the border between the Free State and KwaZulu-Natal is planned to be fully operational in 2014. The station will comprise two dams (one at the top and the other at the bottom of the escarpment), underground waterways, an underground powerhouse complex, access tunnels and access roads. The station is 350 m underground
The tailrace tunnel lining for the lower waterways is 72% complete and excavation of the surge chambers is close to complete. The spiral encasement for Unit 3 was completed on time, while the transformer Unit 4 enclosure walls to mezzanine floor level are complete.
The 4,800 MW Kusile power station, located near the existing Kendal power station in the Delmas municipal area of the Mpumalanga province, will be one of the largest coal-fired power stations in the world once finished. The first unit is planned to go online in December 2014. Kusile will be the first power station in South Africa to have flue gas desulphurisation (FGD) installed. FGD is a state-of-the-art technology, used to remove oxides of sulphur, such as sulphur dioxide, from exhaust flue gases in power plants that burn coal. To help conserve water, the plant will use an air cooling system.
Significant recent project achievements at Kusile include the completion of the chimney concrete works and the commencement of the flue can installation in the west chimney, the lifting of the Unit 2 boiler roof grid and commencement of Unit 2 boiler pressure parts work, the start of Unit 3 boiler steel erection, the start of ash silo concrete sliding works, the completion of the final ACC column concrete sliding works, the start of cable racking, and the completion of the Unit 2 turbine pedestal concrete.
Currently there are 13,560 people on site at Kusile with 54 contracts having been awarded to date. The first concrete at Kusile was poured on the 3rd of March 2009.
