Whatever the magnitude of the proposed increases, South Africans are in for some very uncomfortable increases in the price of electricity - the result of a failure to heed warnings and plan appropriately. The electricity saga could well repeat itself in the next few years in Gauteng's water supply.
South Africa is not well-endowed with water. Its rainfall is well below the world average, and commentators such as the renowned scientist, Dr Anthony Turton, have pointed out that it is rapidly running out of options and has largely committed its water supply. This may be aggravated by climate change. Gauteng has another problem: it is South Africa's economic hub, yet it does not have the local water resources that make large settlements viable. These need to be brought in from elsewhere. But its population continues to expand through both birthrate and in-migration.
Meanwhile, the state of its water supply infrastructure is a cause for concern. It is aging and in many instances approaching the end of its lifespan. Some facilities will need refurbishment. Some will need expansion. Acid mine drainage - the flow of severely acidic and polluted water from disused mines - is another matter demanding attention.
The Democratic Alliance is aware that the Gauteng Provincial Government is worried about the state of the water supply system across the province. We have been informed that some R40bn-R60bn could be needed to deal with maintenance and refurbishment issues to stop the pollution of our natural waterways. The failures of municipal governance - much in the news lately - are a key issue here for the water supply system.
This concern was echoed in 2007 by the then Minister of Water Affairs and Forestry who indicated: "Although the funding for national water resources infrastructure maintenance can be regarded as adequate the current funding allocated across other spheres, especially at local and regional level, for bulk water infrastructure investment, maintenance, refurbishment and replacement is totally insufficient."
Gauteng, ultimately, will have to "do more with less". Dr Turton has warned that South Africa would increasingly need to turn towards innovation to deal with these problems. This is the route that such water-stressed countries as Israel have had to go.
