Electranets, Hippos at WEF and Cheetahs.

Electranets, hygridding, network of mini grids, the new idea in electrification by any other name sounds just as cool.

After the hopeful and progressive afterglow of TED Global, I find myself thinking about three things this morning. The first is ??What do Africans (including myself of course) aspire to be??? what reality are we creating for ourselves and our children? and As Nik Nesbitt of Kencall would say, ??how do you make Africa relevant???

I will look at several stories and ideas today with energy-tinted glasses , and attempt to make them relevant despite the fact that the topic of energy is not as sexy as say? Africa 2.0 or Andrew Dosunmu??s pictures.

The idea of an electranet or hygridding is not new, I have blogged about it several times and remain a staunch proponent of it.

The reason why I see energy generation as important is because as Ory said, the circumstances under which you live in Africa determine where you end up. It??s not a wonder that I am here writing. Even though I lived in a rural home, we had electricity and thus the amenities that come with them, most important of these being the TV and radio, which opened up my mind to what is beyond the rural world. Point is if I wasn??t at a well lit table with my dad showing me how to do math problems in preparation for my exams, would I be here? In this African century, the tools that will continue to expand horizons for many in Africa include not just the TV and radio, but the mobile phone and computers. For Africans to fully participate and compete in the global market, information access is paramount, as is power to run the tools of information dissemination.

??If it doesn??t need electricity, it can??t be any fun? ?? Blooregard Q Kazoo, Fosters home for imaginary friends.

*the quote from bloo is just to liven up this post.

Rural electrification is a goal for many African governments, with demonstrable progress in Kenya where more people are getting tied to the grid as we speak. In my opinion African countries have a chance to shape the energy transformation in a way that is contextualized and appropriate for their communities. As reported by Ethan Zuckerman LHKB (The long haired king of blogging), the ongoing discussion at the WEF forum in South Africa brought up the issue of how this transformation should occur. ???top down in major hydro, gas, coal and oil plants? or bottom up with mini grids making up an electranet ??a flexible, adhoc structure like the Internet that could allow power producers to spill their excess power onto a network and sell their power.?

Now to the Hippo like part of this post; also from Ethan’s excellent coverage of WEF HippoCon….

An audience member – a builder of large power systems – objects to the direction of the discussion. He points out that there??s a massive, continent-wide deficit in electricity, exacerbated by the hyper growth of countries like Ghana, which are rapidly using up their generation capacity. ??Doing this bottom up will be too little, too late.? Human and animal power won??t allow people ??to run a blacksmiths or a machining shop? – instead, the investment must be from the top down in major hydro, gas, coal and oil plants.

This is the kind of thinking that results in huge IMF loan funded projects being inaugurated by Hippo-like presidents where the country has a power plant alright, but the debt incurred from setting up said power plants saddles the country for decades to come?Bono??s activism notwithstanding. In the face of ideas like the electranet being shared, we have a major builder of power systems having a voice at the table saying that it would be too little too late. He is entitled to his opinion as I am mine? and in a future where Africa is more relevant, we would have a cheetah-like leader at the WEF articulating what works for Africa. Not what someone else thinks is too little too late.

What I would wish for is for the Cheetah leader to articulate something along the lines of electranets and mini grids forming the foundation for energy expansion. Why? It is possible to have a grid that utilizes renewable energy from different sources, be it wind, like the marsabit wind turbine power plant or CSP concentrated solar power plants in the sahara. The large scale projects can provide a large chunk of the energy needed just as hydro electric power has done over the last decades in Kenya powering many industries. This is a top-down approach indeed, but look at the technology used, it is clean and renewable, not dirty ?? coal and expensive ?? oil. Africa cares about global warming too you know, what with the report from the economist pointing out that Africa will suffer more from climate change, the energy transformation of Africa needs to take into account this very fact.

That is why it is time to include the idea of netmetering or ??electranets?? and having the people also contribute to provision of energy by being able to sell power to the grid as shared at the WEF. It would be self sustaining and even empowering. Yeah the pun in emPOWERing is very much intended.

Energy transformation may already be happening we just need to open our eyes, just read over at Bankelele??s about kenya??s energy budgetary allocation

energy rural electrification to be continued as mini grids will be set up in large towns. 8 billion has been allocated to deal with (anticipated?) energy shortages so they don??t hamper manufacturing processes

The next part (the aspirational bit) can we complete the loop of using mini grids, integrating renewable energy into the mix, community involvement in the form of partnerships to generate electricity and large scale investment funded projects to light the dark continent?

The big idea from TED was African solutions to African problems; I would like to add that sustainability and renewable energy can be just as African as fufu, ugali and matoke. We just have to open our eyes to the possibility, and urge our leaders to pursue strategies that include renewable energy sources. If Denmark can generate 20% of its energy needs using wind, and continue to pursue policies geared towards weaning themselves off of oil, well, Africa need not reinvent the wheel, there is clearly a roughdraft that energy policy can take into account when formulating the policies in energy transformation.

Back to the question that started this post ??What do Africans (including myself of course) aspire to be??? ?? We aspire to be self reliant, self determining and forward thinking.

What reality are we creating for ourselves and our children? ?? A reality of hopeful prospects in a clean environment free of pollution and degradation

??How do you make Africa relevant??? ?? By making choices that work for Africa. Let??s really think about what is appropriate not just for the short term but for the long term too.

Update: Watch John Doerrs’ TED talk this year, its along the lines of what i was attempting to say. Very powerful, inspiring and spot on.

Wind Turbine Power Plant in Marsabit, Lekuton and Craftskills.

Joseph Lekuton M.P speaking at TED Global.
lekutonTed

For a brief run down of his talk at TED, please click here.

While in Arusha for TED I got the chance to speak briefly with Hon. Joseph Lekuton, M.P of Laisamis constituency; about renewable energy and specifically what is going on in his constituency. Hon. Lekuton stated that there is a wind power turbine power plant being constructed between Mt. Nyiru and Mt.Marsabit. The corridor between these two mountains has very powerful winds that are going to be harnessed for energy generation. He informed us that the project is currently underway and is slated to be tied to the electricity grid, specifically through the Turkwel gorge hydro power plant.

The opportunity to build and operate the turbine was posted by Bankelele back in Dec 2005, and incidentally, he introduces me to the man who is making it happen today. TED brought together the ‘Cheetahs’ like Mr. Lekuton and Mr. Simon Mwacharo, and I am glad to report here that following their meeting at TED Mr. Lekuton ordered several wind turbines for schools in his constituency from Simon Mwacharo’s Craftskills company.
Business Daily Africa reported today on the wind turbine power plant in Marsabit which is in Mr. Lekuton’s constituency, read more here.

Other News – “Dealers in solar panels have urged Kenya??s standards body to intensify quality assurance measures against imports and false labelling of poor-performing panels.”

**Energy transformation is happening as we speak, with renewable energy sources such as wind and solar having a greater role to play in Africa’s energy future!

PS: White African’s site is back up, see “Thinking About Africa 2.0″ for thoughts on the tech future of Africa.

Wind and Solar energy System Hybrid – Simon Mwacharo

Solar is the future of Africa: Simon Mwacharo gave a wonderful talk today at TED. His company is Craftskills.

He pointed out the challenges of getting power to rural areas, these being

  • Cost of transmission
  • Virtually no government acknowledgment and participation in encouraging renewable energy in the last few years.
  • Previous erroneous pairing of low rpm batteries with solar panels that resulted in a failed system. This made people skeptical of wind and solar systems for awhile.

For example, it takes about Ksh 100 for a rural person to go to a place that has power in order to charge their cellphone. This need not be the case at all, because battery charging stations can be set up in close proximity to most people in rural areas. His company has set up systems in Kenya, Tanzania, Rwanda, Cameroon and in the near future ivory coast. (White African asked the question about which countries his companies have been working in).

He had a powerful graph showing how 85% of Kenya (africa?) is not connected to the grid. The striking thing about Mr. Mwacharo’s company is the use of locally available materials and labor to create the systems. The inverters are made at a local university, the wiring and set up of the systems is done in his backyard. The fiberglass is locally cast though he imports the solar panels and magnets from China. His is a company that completely localizes renewable energy to provide power in a simple yet elegant way. Use of wind, complemented by solar and higher efficiency LED lights make this a very nimble system for off grid power provision.

During the q and a session, A gentleman asked a question whether netmetering is possible such that a hygrid (Grid tied solar sys) is possible, where excess energy generate by the homes can be sold back to the power company. Mwacharo answered by pointing out that the systems his company has deployed so far are not necessarily grid tied at this time, they are still off grid and not integrated.

I think that Mr. Mwacharo’s talk is very important for Africa, because it exemplifies that solutions to the ‘dark continent’ lie in the backyard of Africa’s homes and the universities in Africa. Bridging the ‘lighting gap’ is possible without continuing reliance on fossil fuels but with african ingenuity such as what he has shown us today.

Note that Yidris Mohammed has pointed out the the next big opportunity in Africa is the generation of power. Can we as Africans be so bold as to aspire for a grid tied system that can light up our continent in a clean, efficient and economically enhancing way? I firmly and resolutely believe so. It makes sense, and yes, Africa deserves to be brilliant. Not just light, but brilliant.
Thank you Mr. Mwacharo! For writing the first chapter in the energy transformation of Africa.

Nest Home Visit – June 2nd.

As JKE had mentioned on this post , Hash, Ntwiga, Mental and I went to visit the Nest home in Limuru.

Its a remarkable place, not just because of the children, but because of the great job the caretakers are doing of taking care of the children of imprisoned mothers. In speaking with the manager lucy, we learned that more often than not, the children have to be taken to hospital before being admitted to the Nest home, this is often because some of the children are severely neglected and need treatment. This generates quite a bill for the home, and is one of the challenges they are facing amongst other issues such as capacity, they cannot admit all children referred to the home.
The great thing that the nest home does is rehabilitate the mothers once they are released from prison, giving them small loans for income generating activities like selling vegetables. Lucy noted that there is a high collapse rate of businesses due to some mothers not reforming, but that they have had a few successes.

It was an incredibly wonderful time, the children are amazing and just full of joy. I cannot put into words how enriching the experience was. [vid taking too long to upload, will try again tomorrow.]
The thoughtfulness and kindness of people around the world contribute to these children’s welfare. A thoughtful gift that we saw at the home were solar water heaters which ensure that the home has hot water for cleaning, cooking and other uses.

The home was very clean and organized, its a blessing that these childrens’ lives are enriched, and in turn also enrich all of us.

BOGO – Solar flashlight!

JJR has a post on the BOGO light, a solar flashlight.

A light, simple and well designed flashlight great for rural areas where there isn’t much electricity, plus everyone needs to have a flashlight in case of an emergency.

BoGo means Buy one, Give one. We want our lights to benefit the less fortunate; therefore, with each light purchased in the developed world, a second identical light will be donated to an organization that will distribute it in the developing world with our direct financial support

You can read about the success stories which just warm your heart…

The BOGO light is also available at Whole Foods markets around the US, which is where i first saw it, it costs $19.99.

CSP on BBC

Concentrated solar power (CSP), a topic mentioned on this blog; was part of tonights’ BBC world news on bbcAmerica tv and pbs. DKfactor highlighted csp better on this post.
The piece was about a fully functioning zero emissions solar thermal power plant in Spain. It produces 11MW and supplements the energy in Seville. In the summer as it gets hotter, the system generates more energy.Mirrors point the sun’s rays onto boilers which generate power the age old way – steam turbines. Read more about it here.
Note that this is different from the photovoltaic systems i typically blog about…no PV on this one. Mirrors, lots of mirrors.

Thanks for the link Whis!

Use of Solar Vs Kerosene in cameroon

This is an article from Cameroon by Sylvestre Tetchiada, reporting on solar energy use for rural electrification. Interesting stats. Not entirely clear on whether actual use of solar has ‘muscled’ out kerosene, 60% of the 17 million population still use kerosene, what percentage or what stats point to the ‘muscling’ out of kerosene by Solar any increase in the last couple of years? If so by how much? I do realize that getting specific data on stuff like this can be problematic, so please pardon my ‘reading between the lines’. It is still a very good article, it points to the benefits of solar vs kerosene use – No smoke in the eyes of teachers grading papers at night, better quality of life, and the myriad uses of solar. Good stuff. The other good thing pointed out in the piece is the transfer of knowledge from the notable Barefoot College in India. This is the classic ‘showing someone how to fish’ rather than giving someone the fish which they will eat for a day. It is also an example of good use of aid money from UNDP – the training and involvement of women in this program.

Solar power is not without its own costs. “In our country, you need on average 500 to 1,000 dollars to equip a home (with solar electricity systems), and most do not have the money,” Yves Ngouala, an economist based in Yaoundé, told IPS.

But, this hasn’t stopped the Association for the Support and Assistance of Women (Association pour l’appui et le soutien à la femme, ASAFE), an NGO based in the economic hub of Douala, from sending four women to India for six months’ training in solar power technology.

The women were briefed at the Barefoot College, an organisation founded in 1972 to equip rural people with various skills, which has branched out across India.

“The women we sent to train in the technique of solar power?will return to electrify 100 houses each in their respective villages, where inhabitants made use of kerosene and wood for cooking and heating until now,” says ASAFE President Gisèle Ytamben.

It will be interesting to find out how the program goes. Obviously i am biased here but you know if women are involved…It will surely be something successful.

The Cameroon government has some catching up to do, by eliminating import duties on solar panels just like Kenya did June last year.
Thank you Whis for sending me the story.

Cellphone Base stations powered by wind and solar

This post by Emeka Okafor of Timbuktu chronicles makes me just want to jump up and down with glee. “Simmer down now and write the post AFM”.O.k o.k. This is exciting!awesome!totally cool! omg! “Chill out and quit acting like a teenager seeing orlando bloom for the first time” o.k o.k! – Serious face on now…

image from TC - solar base stations
The post by TC is about cell phone base stations run by wind and solar power currently in use in Namibia. These may already be in use by Celtel, since these stations were delivered to them in 2005 (per this post, also by TC) Does anyone reading this blog know if Celtel is currently using such base stations? If you have pics, or more info, please comment. TIA. I have made some enquiries and will update you once i know for sure.

Update:Sunday March 11th: Celtel does indeed use the wind powered base stations in kenya, a company called WinAfrique provides the wind turbines.  Thanks Bankelele!
Why is this so apropos? There is now no excuse for mobile phone companies to neglect areas such as North Eastern Kenya in providing cell phone services. Places like baragoi and other remote parts of kenya can have cell phone coverage if more of these base stations are used. The initial cost of the solar panels and wind turbines will be paid off quickly and the mobile service provider will recoup their money in no time. One thing would be to find the most important outposts such as schools, boreholes, places of religious importance such as kisima – near maralal; install the base stations there.

Solar Concentrator update

I made some inquiries about the $450 solar concentrator (Sun Flower) that i blogged about last year
sunflower

I contacted Andrew Beebe of energy innovations, about their plans for making the sunflower available for purchase: It is not available for sale in international markets until 2008. According to the EI site, they are still testing and refining the Sunflower.

This is one product I am looking forward to testing it in Kenya once it becomes available, mainly because it is cost effective, and suitable for those wishing to still be tied to the electricity grid, but supplement their energy needs or even resell it to the Electric company.
AOB:

Ugo Okafor of African Architecture had blogged about a solar Chimney/Concentrated solar power plant in Sahara desert. This is a very powerful idea that apparently has a precedent. Bruno De Wachter writes on Leonardo Energy

In the current photovoltaic industry boom, another solar power technology has somehow been overshadowed: Concentrated Solar Power (CSP). CSP uses mirrors to concentrate the sun rays on a pipe or vessel. These contain a gas or liquid that is heated to around 400° C and is then used to power conventional steam turbines. The technology is proven ?? a CSP plant in the California desert has been functioning very effectively for fifteen years. One major advantage of CSP is that the medium heated during the day can be stored in vessels to keep the turbines running at night.
