Its 300 metre tall chimney was built in 1979, and is one of the tallest structures in the country.

Komati is one of power stations with a common steam range, meaning that its nine boilers jointly feed the nine generators.

In 1988, three units at Komati were mothballed, one was kept in reserve and the other five were only operated during peak hours.

In 1990, the complete station was mothballed until 2008 when the unit 9 was the first to be recommissioned under Eskom's return-to-service project.

The decommissioning was supported by the World Bank as part of the Eskom Just Energy Transition Project, alongside a package of international support for decarbonization in South Africa known as the South Africa Just Energy Transition Investment Plan.
