City is leading by example – own operations

• City retrofit of 14 of largest buildings

• Smart metering, energy management training

• More efficient street & complete retrofit of traffic lights.

• Saving City R25 million per year. 3 to 7 year payback periods

The effects of wasting electricity were demonstrated to Capetonians using community press, community centres, the internet, as well as by harnessing tactical opportunities.

Providing information on how to save electricity

According to the City’s Customer Satisfaction Survey results, this has increased from 2.9 in 2009/2010 to 3.4 in 2013/2014.

Estimated cost of load-shedding to Cape Town

• Outages in 2007/2008 cost the economy R50 billion (NERSA).

• For current load-shedding top economist estimates R 6 billion

per month for Stage 1, R12 b for Stage 2 & R24 b for Stage 3.

• Initial estimate: City losing over R1 billion per month.

• Energy Efficiency Campaigns

cost cities a fraction of this

to reduce demand.
