Finland’s Wartsila is to supply and construct a complete on-site power plant in South Africa for Sasol New Energy Holdings.

The deal involves the delivery of the complete power plant, including engineering, procurement and contracting. The plant will be powered by 18 Wartsila 20V34SG generating sets running on natural gas.

The turnkey power plant will be installed at the company’s facilities in Sasolburg, south of Johannesburg, and will generate baseload electricity for the company’s own use, with excess production eventually sent to the national grid.

Wartsila says the plant will help Sasol reduce its carbon footprint with one key factor being that the plant can operate with a closed circuit cooling system, thus consuming no water, an important factor in a region where water is scarce.

The company also says the efficiency of the gas engines is especially important because its Sasolburg plant is located at an altitude of 1700 metres above sea level.
