Cape Town - Eskom said on Monday that its door-to-door campaign to exchange old-style light bulbs and non-working compact fluorescent lamps (CFLs) with new CFLs had achieved evening peak demand savings of 67MW.
This is enough to provide more than 80 percent of the power needed for a town the size of Mthatha in the Eastern Cape.
The Energy Efficient Lighting Exchange Programme is one of Eskom's key initiatives to keep the power supply stable.
Out of the more than two million lamps installed, at least 1.3 million had been independently verified, the energy parastatal said in a statement.

The first phase of the roll-out, which started in November 2015, involves the installation of 4.8-million CFLs; a further 5.2-million will be installed in all nine provinces by end March 2018.
Eskom said the programme would continue to play a crucial role in helping homeowners to reduce their monthly electricity bills while keeping South Africa's power supply stable.
