Following extensive modernization with the SPPA-T3000 I&C system from Siemens, six of the nine power plant units at the Komati coal-fired power plant in South Africa are since the beginning of 2012 back on the grid. Planning is already underway to modernize the three remaining units. Recommissioning of the six power plant units in Komati has provided Eskom, a state-owned South African power utility company, with an additional capacity of 650 megawatts (MW). Modernization efforts using electrical and I&C technology from Siemens have not only increased the efficiency of the power plant units and reduced operating costs, but also extended the power plant's service life by an additional 15 years. By providing over 2,400 new jobs, the refurbishment measures have additionally had a positive impact on the employment situation in the region.
The Komati power plant is located in the same-named city of Komati in the province Mpumalanga in South Africa. In 1988 three of the plant units were mothballed while the other six where only used as a reserve capacity for bottlenecks in the power supply. The quiescence of the whole power plant followed in 1990.
"To recommission a power plant that is over 50 years old after it has been shut down for more than 20 years is not an easy task. Modernization measures had to be carried out according to a tight schedule due to the power shortage, which posed an additional challenge," stated James Hebren, project manager at Siemens Energy. "Thanks to our outstanding team and our extensive experience, we were able to successfully complete our work between December 2011 and February 2012," Hebren added.
