Energy Poverty

The African continent has been plagued by energy poverty ever since Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale in the early 1870’s. In the words of Bob Dylan, “the times they are a changin’.” Listen to  Energy Security Services Africa MD Gareth Gregory as he shed’s some light on the dark continent at the Power & Electricity World Africa 2017 conference.

Africa Poised For Renewables Boom

With the Power & Electricity World Africa 2017 conference recently completed in Johannesburg, Africa seems poised to take advantage of massive growth in off-grid solar. In an article by Anine Kilian in ENGINEERING NEWS she says according to South African Solar Photovoltaic Committee chairperson Jo Dean “Off-Grid solar power could help lower the energy costs for 138-million households in Africa that live on less than $2.50 a day and spend about $10-billion a year on energy-related products, including charcoal, candles and kerosene.” (full article here)

An article published by UC BERKELY reiterates this point stating “Renewable energy in Africa has a robust future.”

They concluded that with the right strategy for placing solar and wind farms, and with international sharing of power, most African nations could lower the number of conventional […]

BUILDING A GREENER FUTURE AT SANCTUARY CHIEF’S CAMP

We recently completed a beautiful 140kW off-grid system for Sanctuary’s Chief’s Camp. Take a look at what they have to say about their decision to go solar.

“Taking care of nature is one of our most important tasks, not only as a company, but also as individual people. We can all do our bit to help conserve wildlife and protect local people and places. At Sanctuary Retreats, we have always been focused on this, working with local people and finding sustainable building techniques that cause as little impact on the environment as possible.

As Sanctuary Chief’s Camp undergoes a complete rebuild, protecting the environment was at the forefront of our minds. With a history of managing award winning eco-friendly camps and lodges, we knew we had to go further than ever before.
Our Vision of the Future
When we look at the future, we see green, and this is something we felt necessary to […]

Total blackouts is a real possibility

Eskom recently explained that the reason it implemented rotational load shedding was to avoid a potential national blackout in South Africa. Such a blackout would be no small matter, the power utility said, as it would take weeks to restart the grid if South Africa went completely dark. Why would excessive demand in some parts of South Africa’s electricity grid cause a national blackout and not just a blackout in that area, though? Asked about this, director of EE Publishers and electricity expert Chris Yelland explained that it is the very safety features built into electricity equipment to prevent catastrophic failure that would lead to a blackout. Cascading trip-out is a real possibility. “When demand exceeds supply, what happens is you have overloading of generators, transformers, cables, and switch gear,” Yelland said. To protect against the massive damage such an overload would cause, trip mechanisms are installed in such equipment. […]

Eskom disintegrating | What the future looks like

An article from MyBroadband quotes: “As the power system teetered on the brink of collapse in January, Eskom chief executive Tshediso Matona stated the obvious: “We have arrived at a point that does not allow us to ignore the health of our plants”. He told us how the utility would do more maintenance than ever before, with the not-so-thinly-veiled implication that previous chief executive Brian Dames and his executive team sat around playing solitaire and did the absolute bare minimum maintenance in the nearly four-year period Dames was in charge. Said Matona: “If we did not decide to keep the lights on during the World Cup, South Africa would not have been where it is today.” The problem, of course, is that the World Cup was a two-month period right at the start of Dames’s tenure. I don’t know Dames, nor have I spoken to him since the announcement of his […]
