Electricity
Enough electricity to power the city of Mangaung (Bloemfontein) was saved during Earth Hour on 26 March 2011, said the state-owned power utility Eskom. Eskom measured the reduction in electricity used from 20:30-21:30 against typical consumption for this time on an average Saturday evening. According to their measurements, South Africans saved 350 MW of electricity.
The medium voltage (MV) and high voltage (HV) switchgear market in South Africa holds high growth potential for manufacturers. Eskom will continue to implement its grid-strengthening projects, boosting growth in the HV segment. The MV segment has become increasingly competitive and is threatened by decreasing margins. The ongoing lack of maintenance in the distribution network by various municipalities will provide a longer-term opportunity.

In South Africa’s quest to ensure that electricity supply meets the growing electricity demand over the next 20 years, it is important to understand the role that co-generation can play.

After nationwide public comment sessions and months of planning, South Africa’s Department of Energy (DoE) finally gained approval from Cabinet and released the Policy Adjusted IRP (Integrated Resource Plan) in March 2011.
As part of a recent energy-load shifting project, SmartRipple geyser-ripple control receivers were installed in homes within the entire Nelson Mandela Bay Metro (NMBM) area. This is not new technology, as it has been used in homes in Europe and certain parts of South Africa for years.  
Cullin Africa, a BEE-company that has been in operation since 1998, has been supplying high voltage overhead line gear to Telkom, Transnet and the local power-utility Eskom for a number of years.

Powering the future

The IRP 2010 isn’t an “energy plan” or an “infrastructure plan”, it’s a electricity generation capacity expansion plan. It is required by law and is the accountability of the Minister of Energy.
Malawi’s energy sector, which had 63 days of power outages in 2009, has received a significant boost from the US. The Millennium Challenge Corporation has given Malawi a US350-million grant to upgrade the country’s power supply, whose dire condition is a major brake on the nation’s economic growth.
Mining and industry in Zimbabwe have been hurt by power shortages over recent years. In an economy which is only starting to recover from hyperinflation that crushed the economy about two years ago, its power shortages have left many businesses in shambles.
