Toyota South Africa

In August 2010, Toyota South Africa signed up as a Host Plant of the IEE Project. As a result of the IEE Training courses, Toyota SA implemented an Energy Management System (EnMS) and proceeded with the optimization of specific industrial systems resulting in a considerable reduction in electricity usage.

The implementation of an Energy Management System (EnMS)1 at Toyota SA resulted in a reduction in electricity usage which has translated into cost-savings of more than R4.8 million over a two-year period (2010/11).

A total of 55 Energy Systems Optimization (ESO) initiatives have been implemented since 2010. Of these, 25 projects were started in 2010 and continued over 2011, during which an additional 30 new projects were also initiated.
