Reducing site grid disconnections
Diesel-fuelled power generation is much more expensive than drawing power from the grid. However, at Helios Towers Ghana, sites had been consuming unnecessary fuel because they were being disconnected from the grid. This was caused by maintenance partners failing to top up prepayment meters and ensuring the grid supply. In turn, this was impacting on the operational expenses for these sites.
The Six Sigma solution
We analysed the causes for the disconnections, and measured payment times to understand if the process was in control. We then mapped the current state of the process to identify and evaluate waste, and prioritised the actions needed.
The project took three months from defining the problem to implementing the improvement.
In the period from December 2016 to September 2017:
- 85,000 generator hours saved annually for 12 sites
- US$70,000 saved in fuel costs annually for 12 sites
