EE Initiatives: CFL Mass Rollout

2014/03/27 5

• Objective: Replace Incandescent with CFLs

• The programme is entirely on tender bases

• Programme consist of:

• Supply /procurement of CFLs

• PM Companies per Region (Operating Units)

• Multiple Installation Teams per Region ( Operating Units)

• Crushing and Disposal (both Incandescent and CFLs)

• Preference is given to small companies based on BBBEE level status.

• Target areas: Predominantly lower LSM and few higher LSM

• Temporary jobs creation in communities where the rollout is targeted.
