The Santa Matilde sugar cane processing plant in the Honduras is enjoying the sweet taste of success thanks to ABB’s variable speed drives (VSDs). In fact, the plant is now so energy-efficient that it sells its excess electricity into the local grid – bringing in an extra one million dollars (US) of income every year.
The reason for this impressive improvement is that previously the plant’s cane-crushing machinery was driven by steam produced by burning bagasse - the fibrous waste product left after sugar cane is processed.
But now the steam is used to propel turbines that generate electricity. And that electricity feeds the new ABB ACS1000
VSDs and induction motors
, providing the plant machinery with both exceptional energy-efficiency and precision control.
The customer is satisfied with the results. Ing. Jorge Arriaga from the Santa Matilde plant, said:
“We are very pleased with the performance of ABB’s ACS1000 variable speed drives. The overall energy efficiency of the Santa Matilde plant has increased tremendously. Today, we are not only energy self-sufficient, we have also increased our annual revenues by approximately one million dollars by selling excess energy to the grid. Furthermore, the process runs much smoother than before.”
Crushing cane since 1938
The Santa Matilde plant belongs to Compania Azucarera Hondureña S.A., founded in 1938 and one of the largest sugar companies in Honduras, Central America.
