South Africa households account for 17% of electricity use, but that increases to as much as 35% during peak periods. Geysers, especially in middle and lower income households, are the primary consumers of total electricity and contribute substantially to morning and evening peaks. Regulation set a limit on the maximum allowable heat losses exists, but it was formulated many years ago and had never been improved – making it low and ineffective.

Numerous attempts to reduce the allowable losses proved futile, primarily due to strong resistance from the industry. A collaborative effort to address each of the barriers was initiated in 2011 and led to legislation being passed in March 2016 which capped the allowable 24 hour standing losses for a 150 litre geyser from 2.59kWh to 1.38kWh. This is conservatively estimated to save 3.82TWh by 2030. 1 TWh is equal to the sustained power of 114 MW for a period of one year.
