Does it supply sufficient electricity for the school and "boarding school community" ? Is the the limiting factor the ability to fund diesel , or simply the power out put of the generator ? I read that the 4 existing solar panels are sufficient for all lighting in the boarding school community, is this accurate ? And finally, i have been trying to find the exact location of the new high school. So my question is, were in the settlement is it located ?

It is our understanding that there aren't very many in the community, so is it a privately owned business? Can anyone use it, or is it only operated by employees, who charge a fee? Or is it simply community-owned? We were also wondering how big the plots of land given to each 'resettler' will be, and whether there are any plots of land in the current refugee camp? Are they used for farming, or are the refugees fed by UNHCR? Thank you so much! #2 Thu, 09/15/2016 - 18:34 Alison Stoakley (EWB Australia) Hi Madeleine, Apologies for the delay getting back to you. I've pulled together a few pieces of information you might find helpful: At the hammer mill shown in the pictures on this website, it costs everyone 1.5 kwacha to grind a 5L bucket of maize. This is done by hammer mill employees (a bit of information is posted on this thread: http://www.ewbchallenge.org/unhcr-zambia/forum/dust-masks All of the hammer mills I have looked into so far were originally provided by UNHCR, however I will follow this up further to see if there are any that had different origins. Everyone in the community is able to use the hammer mill, but there is also the alternative of pounding the maize manually if a household does not want to pay for the hammer mill services. The plots of land in the resettlement area are 5-10 hectares. In this area, you might find the Livelihoods video> posted in the 'resources' section of the website interesting. Many refugees in Mayukwayukwa are engaged in subsistence farming and those who are considered in vulnerable situations will either be connected to a food program (particularly children in schools) or cash-based program - there is much more information on this area in the UNHCR resources. Good luck!

A 40kva generator (which is said to be inadequate to handle current demands) would be able to power 150 fridges. If you could clarify what is demanding the largest quantity of power, it would make it easier to suggest alternative power sources and judge what the required power production should be. As someone has enquired about before, could we have the make and model of the current diesel generator? Alternatively, if we could know how long it runs on the 1,215litres per month it is allocated, that would help us determine how efficient the generator is. The current units used (KVA) only refers to the amount of power drawn by the generator and not what it actually produces as efficient power, as well as other losses, disallowing the calculation of efficiency. Thanks in Advance, Ashlee Nolan #2 Mon, 08/29/2016 - 14:36 Alison Stoakley (EWB Australia) Hi Ashlee, Building off the information in this discussion thread: http://www.ewbchallenge.org/unhcr-zambia/forum/existing-diesel-generators (which I think your questions are referring to) the 40kVa diesel generator is the one that runs every day for approximately 5 to 6 hours (about 1 hour in the morning and 4 hours in the evening). There are photos of both diesel generators in the 'energy' and 'health' design areas - we will look into more details on these, but please make assumptions based on the resources at hand in the meantime. It may be helpful as you go through the design to think about the other factors that will come into play when looking at how much energy your design should provide. What is the most cost-effective way to go about it (i.e. maybe it doesn't meet all requirements, but it's the best bang for the buck)? Is your design something small that you can test and then scale up? Questions like this can help you determine the most appropriate design, in addition to looking at the current supply. All the best Alison #3 Tue, 09/06/2016 - 10:31 Alison Stoakley (EWB Australia) Hi Ashlee, The model of the larger generator is P40.

Any information you can provide in regards to them would great assist my group as well as provide more clarity surrounding the context. Firstly, what cooking equipment is currently in use? In addition to this, is this equipment used indoors or outdoors and is the equipment shared amongst the community or does it belong to individuals? Secondly, what food is traditionally cooked how is it prepared? i.e. is the food boiled, fried etc. Lastly, can you provide any statistics on the problem of deforestation faced in Zambia? I really appreciate your time in answering these questions. The information you will provide will go a long way in helping construct our overall design. #2 Sun, 08/28/2016 - 10:49 Alison Stoakley (EWB Australia) Hi Lachlan, For more information on cooking practices in Mayukwayukwa, take a look at the photos in the 'Design Area 3: Energy' section of this website. There are photos of traditional three-stone fires and examples of alternative cookstoves which a few households have access to. Cooking is generally done at a household level. For more information on what types of food are common, in addition to the energy photos your can take a look at the 'food processing' and 'climate change and agriculture' section. You should be able to find statistics on deforestation and the impact this could have through wider research for your project. What will probably be useful to keep in mind while your doing this research is that our conversations with community members in Mayukwayukwa reflected a strong awareness of the negative environmental impact deforestation and a desire to find ways around this. This could be important as you think about how you might communicate your design and engage with the community.

Cheers #2 Tue, 08/23/2016 - 14:39 Alison Stoakley (EWB Australia) Hi David, The fuel-efficient stoves that were shared with us were part of a project that is no longer in operation, so they are no longer being distributed. We were told they are made of clay. For the purposes of your project, please estimate the dimensions based on the photos in the 'energy' section of this website. You might also be interested in the UNHCR resource 'Practicing and Promoting Sound Environmental Management in Refugee/Returnee Operations', which can be found at this link: http://www.unhcr.org/cgi-bin/texis/vtx/home/opendocPDFViewer.html?docid=406c34174&query=angola%20stove While I don't believe it refers to the Mayukwayukwa cookstove project specifically, there is some great information about the implementation of similar projects that could help guide your thinking.

Our group understands that the diesel generators are presently being used in Mayukwayukwa while you wait for funding to repair the hydroelectric generator. We expect that this revenue will arrive before the generators are decommissioned out of age. Therefore, do you have an estimate for when the hydroelectric generator will be operational again, thus, the end lifespan of whatever project we develop. Alternatively, an estimate on the lifespan of the generators (I would expect to be in decades). Thank you for your work. #2 Tue, 06/07/2016 - 15:02 Alison Stoakley (EWB Australia) Hi Jesse, At the moment, the system of diesel generators is not meeting the energy needs of the community in Mayukwayukwa. Similarly, the hydroelectric system, were it to be repaired to it's previous capacity, is also not expected to deliver the amount of power the community would like to see available. A report by the energy authority investigating potential repairs to the system noted that should the plant be uprated as they propose, 'the uprated capacity at the plant will still not be adequate to meet the community's electricity's demand fully'. While this is only one report, perhaps you can think about how your design will supplement this system, should it be repaired. For example, could it enable residents to have access to electricity for more purposes than just lighting? What impact could this have? There are many areas in Mayukwayukwa that currently do not have access to power, even with the existing diesel generators functioning - what impact could a new power supply have for these areas?

Anne #2 Mon, 05/02/2016 - 15:21 Alison Stoakley (EWB Australia) Hi Anne, Glad you are able to access the forum and apologies for the delay getting back to you. You can find a bit more information about the recently opened Mayukwayukwa High School at the bottom of this post by UNCHR Zambia: https://www.facebook.com/UnhcrZambia/posts/772094122879812. The high school currently has a diesel generator that was donated by the German government, however there are additional energy requirements and funds to supply diesel to the generator are difficult to source (hence why alternative energy sources are desirable). It is a boarding school, which is why there are other energy requirements in addition to the classrooms and offices. You can find photos of the energy consuming equipment at the health centre on the 'health' design area. There is also a small centrifuge and CD4 count machine in the lab which I don't believe we have photos of. I've also listed many of the services the health clinic provides on this post: http://www.ewbchallenge.org/unhcr-zambia/forum/water-tower-health-clinic , which could also be helpful when estimating energy use.

What is meant by a health post? We were assuming this means a kind of nursing station: a single roomed dwelling in which a nurse or other health worker would see and treat patients, dispense medicines and dress minor injuries. But I am not finding much information available about this. Mayukwayukwa Refugee Settlement has grown to many villages, are we thinking of powering about 10 health posts or more like 100? Also, what is meant by 'market areas'? Are there many stalls at which residents who sell produce or other goods would benefit from power? Or is some specific equipment/infrastructure at the market needing the power which is not presently supplied? Thank you for your help in getting on, Alison. #2 Wed, 04/20/2016 - 11:49 Alison Stoakley (EWB Australia) Hi Julian, That's correct, a health post provides health services on a smaller scale than the health clinics. They are able to provide basic nursing services and are dispersed around Mayukwayukwa so that people do not have to travel as far to get assistance. In the refugee settlement there is currently one health clinic and two health posts. As a part of the Local Integration Program, the Shibanga health post in the resettlement area will also be upgraded to serve the new residents moving in. With regard to the market areas - if you take a look at the photos on the bottom of the 'food processing' section you can see what parts of one of the current marketplaces in Mayukwayukwa looks like. These areas are generally hubs, so they present an opportunity for sharing access to energy in one location. We were not told of one specific type of equipment or infrastructure that does not currently have power - rather the opportunity is a bit open to imagine what this might look like.

Firstly, which buildings use power in the camp and how much electricity do they use? Do the households use electricity as well (lighting?), and if so, how is it supplied to them? Also do you have a numerical figure for the amount of households in the camp? I read in the 2006 and 2009 UNHCR Mayukwayukwa reports that each household was given 2.5 acres of land to cultivate and grow crops on, and I was wondering if this has continued, and how many households are engaged in agricultural activities? I am looking at an electricity generation and potentially a distribution system in the camp and having up to date information for this would be invaluable. Thanks very much for your time. William Talbot #2 Mon, 04/11/2016 - 11:58 Alison Stoakley (EWB Australia) Hi William, Based on your questions, you will probably find the answers to these posts helpful: http://www.ewbchallenge.org/unhcr-zambia/forum/power-usage http://www.ewbchallenge.org/unhcr-zambia/forum/existing-diesel-generators We don't have an exact breakdown of the energy usage of each building, but we do know how much diesel is supplied to the two diesel generators per month and what buildings these generators are connected to, so you should be able to use this information to make a some reasonable assumptions. Most households do not have access to electricity however some may have a small solar panel. At the moment, we only have information on the total number of individuals in Mayukwayukwa (approximately 11,000) and this is not broken down by household size. When you say 'household' are you referring to a structure or a family unit? I am not sure whether the distribution of agriculture land is continuing for new refugees to Mayukwayukwa or whether this was a one-off program for the refugees who were relocated from Nangweshi - I can look into this for you further. However, in the meantime I can tell you that the majority of households are engaged in agriculture.

Ie households, medical centre and high school etc.. We were wandering what an approximate energy usage is? #2 Thu, 04/07/2016 - 17:38 Alison Stoakley (EWB Australia) Hi Shaun, The energy usage for a household compared to the health clinic and administration buildings is quite different. An outside report by an energy company found that the majority of households would us electricity only for lighting or other small uses and therefore estimated consumption at 300W per household. This is their estimate of the current usage, that's not to say households would not use more should it be available, so perhaps you can add some thinking in your report around this? I've answered some information around the diesel generators in this post: (http://www.ewbchallenge.org/unhcr-zambia/forum/existing-diesel-generators) and that should help you make assumptions around the energy usage in other locations.

This should allow you to make a reasonable assumption for your design based on the size and other characteristics of settlement. The oxen did appear to be healthy. You may also want to keep in mind that these ox are owned by individual households (rather than existing as community property) as this may impact the way you think about how your design would operate/be managed.

Thank you! #2 Thu, 03/24/2016 - 16:05 Alison Stoakley (EWB Australia) Hi Trong, You are correct, the main sources of power in Mayukwayukwa are solar panels and diesel generators. Mayukwayukwa is not connected to a grid, so these power sources would only supply particular discrete locations (i.e. it is not one system for the entire area). I've just posted the average price of diesel here: http://www.ewbchallenge.org/unhcr-zambia/energy so that should help you make estimates around how much a diesel generator costs to run. The limiting factor regarding running the generators is most often buying the diesel to fuel them. We don't have any detail around the particular price of the solar panels in place, but you should be able to do a bit of research around average prices and make a good estimate.

My other question is, did the old hydro generator have a man-made water supply or is there a river flowing close by the village. Michael. #4 Thu, 03/31/2016 - 10:24 Alison Stoakley (EWB Australia) Hi Michael, That's correct, there was a micro-hydro scheme commissioned in Mayukwayukwa in 1993, however there have been periods where it was not operational and it has currently not been operating since 2011. The original power plant was 24kW and operated on the Luena River (if you take a look at the map in the 'resources' section, you can see this river and a waypoint where the turbine is located). There are currently conversations between many stakeholders around how this plant might be re-habilitated or expanded, however as there are numerous factors (apart from the technical requirements) that must be addressed in this process, this specific project was not included in the design brief. I understand there might be elements you decide to repurpose or lessons from this project you might use - and do feel free to be creative! I will highlight that a Zambian power company completed a report on the current state of the micro-hydro scheme in 2014 and noted that "electromechanical equipment was judged to be in a state of complete disrepair" - meaning they believe the turbine and generator would have to be replaced. I hope that's helpful and good luck! Kind Regards Alison #5 Thu, 03/31/2016 - 14:03 Michael Jones Thankyou so much Alison, That information is so helpful, because our group believes that we have a solution to how to rehabilitate this hydro system. We want to create a rainwater hydro generator system for each building that has a power need, so that when it rains and when anyone wants water from the included water tank, the flow of the water charges batteries.

Our solution is centred on options looking at the current disfunctioning hydo turbine generator, and creating a new rain harvesting hydro generator. Could you please explain to me how the current hydro generator used to operate, and how this generator used to connect to the appliances in the village to charge them such as the field office computers, the medical facilities microscopes and fridges, and the school's computers . Also, would you be able to tell me if any of the infrastructure in the village have gutters on them. Our proposed design for the village is to used to the monsoonal season rainfall to create electricity. Whenever it rains this system catches water that runs of the roofs of existing buildings, the water runs into a downpipe, through a vertical turbine system, and then into a rainwater tank. Then whenever the water is needed, another turbine system is set up at the bottom of the rainwater tank above the release value. This means that there are to points on the system where electrical charge is created and also it means that farmers have water for their crops in the dry season. So that we can optimise this system, our group would love to know how the village's existing generator charges the appliances. #2 Wed, 03/30/2016 - 17:37 Alison Stoakley (EWB Australia) Hi Michael, I am just follow up details around the previous hydroelectric system and will post back here as soon as possible. Kind Regards Alison #3 Thu, 03/31/2016 - 11:18 Alison Stoakley (EWB Australia) Hi Michael, I'll try to pull out a few of your questions and answer them here - please post back if I've missed anything! The previous micro-hydro scheme had an output of 24kW and used a 'run-off-river in-stream diversion mechanism' to divert a small fraction of the Luena River and generator power. What is important to note here is that there are quite a few new facilities, such as the high school, that have been constructed more recently and would not have been supply by this system. The current diesel generator which supplies the guest and staff houses, administration buildings and other areas in the Mayukwayukwa settlement is connected to these locations through a simple single phase distribution network. I am not aware of gutters being used on buildings currently - but this would be a great thing to look into if you're interested in rainwater harvesting! It may also be useful to think about the particular locations you are looking into for your design. Are looking to supply power to individual houses in the resettlement area? The health clinics? The new high school? Thinking about this should help you clarify your ideas. Good luck Alison (Reply to #3)#4 Thu, 03/31/2016 - 14:01 Michael Jones Thankyou for your response Alison, I just have a few more questions: When you say that the diesel generator provides power for the admin buildings and other areas through a single phase distribution network, is this network underground, or is it just cables along the ground or in the air between buildings and through trees? Do you have any materials or resources (timber) in the village that could be utilised for a guttering system? Finally, for the high school and the health clinic, what are the precise appliances in these buildings that need a power supply. The reason for my question is that to make a new 'rainwater harvesting hydro generator' system, which is what our group wants to do, we need to know what the output power needs to be, so that we can design and create the system to produce that needed power.

We intend to re purpose parts of the hydroelectric dam, and we need some rough details. 1. (Roughly) How large is the dam? including depth (or volume of water will suffice) 2. Can we open the dam to let water flow? Or are the valves non-functional too? Thanks! #2 Wed, 03/30/2016 - 17:38 Alison Stoakley (EWB Australia) Hi Zachary, I am just following up details around the hydroelectric dam system and post back here as soon as possible. Kind Regards Alison #3 Thu, 03/31/2016 - 12:26 Alison Stoakley (EWB Australia) Hi Zachary, The system is a micro-hydro scheme that diverts water from the nearby Luena River. It is not a large, conventional hydroelectric dam, instead, a small portion of water is diverted via a diversion weir and intake canal to the turbine.
