MHPS boiler delivered to $9.23bn SA coal-fired power plant

Mitsubishi Hitachi Power Systems (MHPS) has delivered the first boiler for Eskom’s new 4.8 GW Kusile coal-fired power plant in South Africa.

The delivered unit is a supercritical-pressure boiler for the utility’s coal-fired power plant which is being built at a cost of $9.23bn in Witbank, Mpumalanga Province.

Using supercritical-pressure technologies, thermal power plants can generate more efficient power than conventional coal-fired systems, significantly reducing carbon emissions.

It is the third unit from MHPS for Eskom’s Medupi and Kusile thermal power generation projects which put together have an output of 9.6GW.

In a statement MHPS said, “Eskom had previously announced that commercial operations at Kusile Power Station Unit 1 would launch by July 2018. However, thanks to the efforts of MHPS to shorten the construction period, commercial operation was achieved 11 months ahead of schedule.”

The two other units delivered by MHPS are in operation at the Medupi Power Station in Lephalale, Limpopo Province since August 2015 and April 2017.

Like the Medupi power plant, the Kusile coal-fired power plant also features a total of six units with each of them having a capacity of 800 MW.

The plant is expected to have an operational life of 60 years becoming the first South African power station to install flue-gas desulphurisation (FGD) for the elimination of oxides of sulphur. It is estimated to use up to 5,300km of cabling.
