How solar-powered Village in Kenya Outback Kept Lights On During Africa’s Biggest Blackout - Technology Org
People across Kenya were mysteriously plunged into darkness last month as the country suffered its worst power outage in a generation – except for a tiny remote village.
Now experts from the University of Southampton have revealed how their mini grid powerplant, fuelled solely by the sun’s energy, kept the lights on across the community of Kitonyoni, in Kenya’s eastern province.

The solar-photovoltaic plant, the first of its kind to be installed in Africa back in 2012, is just a few metres square in size but creates enough energy to power the village alongside its school and hospital.
It kept Kitonyoni, located in Makueni county, powered during Kenya’s massive outage – which affected most of its 50 million population, including in the capital Nairobi, for almost 24 hours.
Engineers behind its creation, called the Energy for Development (e4D) project which includes the University of Southampton, Ministry of Energy Kenya and Kenya Power and Lighting Company, hope to roll it out across Africa where 600million people have no access to electricity.
Professor AbuBakr Bahaj, from the Energy and Climate Change Division at Southampton, said: “The Kitonyoni villagers were the envy of all Kenya, and people from the surrounding villages rushed into its trading centre during the blackout to charge their mobile phones and appliances.
“Kitonyoni has grown tremendously, by a factor of three, since we installed the e4D plant due to the availability of electricity, a growth not seen in our control village 30km away. I remember that the tailor William, who worked with us from the start, wished for an electric iron to replace his wood heated iron – that was duly delivered the second time I visited.”
The Kitonyoni mini grid consists of solar panels and battery storage connected to a distribution network. It took Prof Bahaj and his scientific team just a week to build the first design – which had a capacity of 13.5kWp of uninterrupted power, giving the villagers around-the-clock power for the first time.
The solar canopy also acts as a rain collector and, during the wet season, stores enough water for a year – a vital feature for Kitonyoni which is not connected to a main supply. According to Prof Bahaj, villagers can also generate income by selling the electricity to nearby towns and cities.
The cause of blackout in Kenya, the longest blackout in memory, remains unclear. But such is the success of the Kitonyoni plant that the Kenyan government has since applied for $150milion worth of funding from the World Bank to build more than 100 mini grids across the country, said its Secretary for Renewable Energy Eng Isaac Kiva.
He added: “The reliability shown by the system in Kitonyoni during the blackout was a testament to the UK and Kenyan engineers to deliver solutions that can be widely replicated and deployed to provide electrical power to over 600 million people without energy in Africa.”
The Kitonyoni e4D mini grid is one of six electricity projects across Kenya as well as Uganda and Cameroon.

HV Substation Design: Powering the Future
High Voltage substations play a crucial role in the transmission and distribution of electrical power. These substations serve as key nodes in the power grid, facilitating the efficient and reliable transfer of electricity from generating stations to end-users. The design of HV substations is a complex and multifaceted process that requires careful planning, engineering expertise, and adherence to safety standards. In this blog, we will explore the essential elements of HV substation design under four subheadings: Site Selection, Equipment Selection, Layout Design, and Safety Considerations.
Tumblr media
Site Selection:
Choosing the right location for an HV substation is vital to ensure optimal functionality and accessibility. Several factors need to be considered during site selection, including proximity to load centers, availability of land, environmental impact, and future expansion potential. Substations should be strategically located to minimize power losses during transmission and distribution, while also considering the environmental and social aspects. Thorough assessments and studies are conducted to determine the most suitable site, taking into account geological conditions, land availability, and the potential impact on nearby communities.
Equipment Selection:
The selection of equipment for an HV substation is a critical aspect of the design process. The chosen equipment must meet specific technical requirements, including voltage levels, load capacity, and operational efficiency. Common components found in HV substations include transformers, circuit breakers, switchgear, busbars, and protection systems. These components must be carefully selected based on the substation's anticipated load, the type of power generation being connected, and the overall network configuration. Advanced technologies, such as gas-insulated switchgear (GIS) and intelligent electronic devices (IEDs), are increasingly being integrated into substation designs to enhance substation testing and commissioning
Layout Design:
The layout design of an HV substation encompasses the physical arrangement of equipment, structures, and connections within the substation compound. Efficient layout design ensures ease of operation, maintenance, and future expansion. The layout should consider factors such as clearances, accessibility for maintenance personnel, and proper segregation of high voltage and low voltage areas. Additionally, safety measures, such as fencing, grounding systems, and fire suppression systems, should be incorporated into the layout. Careful consideration is given to the routing of cables, ensuring minimal interference and optimal signal integrity.
Safety Considerations:
Safety is of paramount importance in HV substation design to protect both personnel and the surrounding environment. Substations operate at high voltage levels, presenting inherent risks such as electric shocks and fire hazards. Adequate safety measures are implemented to mitigate these risks. Protective equipment, such as insulating gloves, safety clothing, and grounding systems, are used to safeguard workers during maintenance and operation. Moreover, the layout design should incorporate clear modern power system analysis signage, emergency exits, and proper fencing to restrict unauthorized access.
Conclusion:
HV substation design is a complex and interdisciplinary process that requires careful consideration of multiple factors. As the demand for electricity continues to grow and renewable energy integration becomes more prevalent, the importance of well-designed HV substations becomes increasingly evident. By embracing advancements in technology and adhering to international standards, we can ensure that HV substations continue to power the future with efficiency, reliability, and safety.

hey, how do you cope with people saying we only have a small amount of time left to stop the worst effects of climate change? no matter how hopeful and ok i am, that always sends me back into a spiral :(
A few different ways
1. The biggest one is that I do math. Because renewable energy is growing exponentially
Up until basically 2021 to now, all of the climate change models were based on the idea that our ability to handle climate change will grow linearly. But that's wrong: it's growing exponentially, most of all in the green energy sector. And we're finally starting to see proof of this - and that it's going to keep going.
And many types of climate change mitigation serve as multipliers for other types. Like building a big combo in a video game.
Change has been rapidly accelerating and I genuinely believe that it's going to happen much faster than anyone is currently predicting
2. A lot of the most exciting and groundbreaking things happening around climate change are happening in developing nations, so they're not on most people's radars.
But they will expand, as developing nations are widely undergoing a massive boom in infrastructure, development, and quality of life - and as they collaborate and communicate with each other in doing so
3. Every country, state, city, province, town, nonprofit, community, and movement is basically its own test case
We're going to figure out the best ways to handle things in a remarkably quick amount of time, because everyone is trying out solutions at once. Instead of doing 100 different studies on solutions in order, we get try out 100 (more like 10,000) different versions of different solutions simultaneously, and then figure out which ones worked best and why. The spread of solutions becomes infinitely faster, especially as more and more of the world gets access to the internet and other key infrastructure
4. There's a very real chance that many of the impacts of climate change will be reversible
Yeah, you read that right.
Will it take a while? Yes. But we're mostly talking a few decades to a few centuries, which is NOTHING in geological history terms.
We have more proof than ever of just how resilient nature is. Major rivers are being restored from dried up or dead to thriving ecosystems in under a decade. Life bounces back so fast when we let it.
I know there's a lot of skepticism about carbon capture and carbon removal. That's reasonable, some of those projects are definitely bs (mostly the ones run by gas companies, involving carbon credits, and/or trying to pump CO2 thousands of feet underground)
But there's very real potential for carbon removal through restoring ecosystems and regenerative agriculture
The research into carbon removal has also just exploded in the past three years, so there are almost certainly more and better technologies to come
There's also some promising developments in industrial carbon removal, especially this process of harvesting atmospheric CO2 and other air pollution to make baking soda and other industrially useful chemicals
As we take carbon out of the air in larger amounts, less heat will be trapped in the atmosphere
If less heat is trapped in the atmosphere, then the planet will start to cool down
If the planet starts to cool down, a lot of things will stabilize again. And they'll probably start to stabilize pretty quickly

Water Solar Heater Price Near Bangalore
Water Solar Heater Price Near Bangalore,Water heating systems are becoming increasingly popular. There are many advantages to using them, including saving money on electricity bills, time savings, and the environment. But before deciding to install a water system, you need to consider how much energy you are going to use to heat your water, what kind of energy you have access to, and whether you want something portable or stationary.Water Solar Heater Price Near Bangalore, contact Jupiter Solar www.jupitersolars.in .
What Is A Water Heater?
A water heater is a device designed to raise the temperature of  water above its boiling point. Most people think about their water heater which can reduce their electric bill and decide to look at their monthly usage. When choosing a water heater, keep these things in mind to get the best value for your money. Purchase a solar water heater ,contact Jupiter Solar www.jupitersolars.in .
How Does A Water Heater Work?
When you turn your water faucet on, cold water enters your house and flows through pipes in the building. As it travels through the pipe, it picks up heat from the air around it and drops down to room temperatures. If you wanted to save some of that energy, you'd need to find a way to capture that heat and put it back into the water. That's where your water heater comes in. But instead, you can convert those unused hot spots into warm water. To know about the water solar heater price near Bangalore,  contact Jupiter Solar www.jupitersolars.in .
Which Energy Type Is Best?
There are two types of energy that go into powering your home -- electrical power (commonly called AC) and thermal (heat). Both work well, though each has its strengths and weaknesses.
Electrical Power
Electrical power works well if you have lots of space. You can run wires under floors or ceilings for high-voltage lines. In addition, electrical power is not affected by weather. And since you only need to provide enough power to meet your own household needs, it doesn't cost as much as other forms of energy. On top of that, you don't have to worry about fuel costs, maintenance.
Tumblr media
Thermal Power
Thermal power does not require any infrastructure. You can attach a hose and water yourself. Since you're using heat, you do pay more for the power. Your home or business still has to be insulated properly, however, so you'll want to factor insulation costs into your budget. Buy water solar heater, buy Jupiter solar water heater , best solar water heater in karnataka. 
Intermittent vs. Constant Flow
Each situation calls for different things, so you'll need to examine your options carefully. For example, you may need a constant flow of water, but that requires a lot of power. Or maybe you need a little bit of power now, but you can store plenty of heat later. It's really up to you to determine what your priorities are.

Preventive Tips to Maintain Safe Electrical Wiring in Commercial Buildings
All the machinery, electronics, and appliances found in commercial buildings, in addition to the vast amounts of lighting, require electricity to function properly. Not only that, but the combined electricity consumption of all of this machinery exceeds that of home wiring. It is not the amount of consumption that causes concern; rather, it is the level of safety, which is why commercial wiring is of such critical significance.
Any deviations in the electrical wiring that commercial buildings have can present significant dangers, including temporary shutdown of business operations, the potential for accidents, and even electrical fires. This is of utmost significance because commercial properties typically employ a large number of people.  
When it comes to the electrical wiring that commercial buildings require, there are special considerations that must be taken because the majority of them do not have the wooden frame that is typically used to run wire through. This is one of the reasons why alternative methods of wiring need to be utilized.
According to the National Fire Protection Association (NFPA), 126 people died in 2020 due to exposure to electricity. From that statistic, three in five injuries occurred from direct electrical contact such as being struck by an electrical arc or direct contact with a live electrical wire. When it comes to the safety of commercial wiring, the Occupational Safety and Health Administration (OSHA) has recommendations and guidelines that can be followed. Here are a few tips to ensure you are using safe practices when maintaining the electrical wiring in your commercial or industrial building.
Put a Safety Plan in Place as a First Course of Action
The most effective strategy to prevent injury is to create a project plan beforehand. During the planning phase, personnel are able to evaluate the equipment and surrounding environment for potential dangers. Planning can guarantee that workers utilize the necessary personal protective equipment (PPE) and interprofessional education (IPE) during the course of their work and that they are aware of the correct power-switching circuit.
Wear Appropriate Protective Clothing and Gear
According to OSHA regulations, workers must always wear rubber gloves, insulating sleeves, and safety glasses. Because the fibers are not very conductive or are treated with a flame-retardant, fire-resistant clothing can also assist prevent injury. Employers and employees can determine whether additional PPE is required during the planning phase. Additionally, workers should avoid wearing any metal, including watches and jewelry.
Ensure Equipment is Used and Maintained Properly  
Electricity is a daily necessity for employees working in commercial buildings. Because of this, they have a responsibility to educate themselves on how to correctly use and maintain their electrical equipment, as well as what actions to take in the event of an unexpected emergency. This can significantly lower the likelihood of an electrical fire occurring.
The following are some additional measures that can be taken to ensure the safety of commercial buildings:
It is the responsibility of the employer to instruct each employee on the proper way to unplug electrical appliances.
Electrical plugs and cords of any kind need to be inspected on a regular basis and maintained in the appropriate manner by qualified personnel.
Prohibit securing extension cords by nailing or stapling them.
Electrical equipment such as computers and other similar devices ought to be serviced on a routine basis by trained professionals.
The use of extension cords should only be done on a temporary basis if absolutely necessary.
Commercial employees use devices and equipment regularly and frequently. Electricity use is higher, so personnel must use equipment properly. Equipment maintenance reduces the danger of faults, accidents, and fire.
Invest in a Ground Fault Circuit Interrupter (GFCI)
GFCIs are portable devices that workers can put into an outlet or circuit to protect themselves against electrical hazards. The GFCI will detect a power surge due to if someone is being electrocuted and will switch off the electricity automatically. Utilizing these tools might serve as a backup plan if something else goes awry during the process.
Contact Schaffhouser Electric for All Your Electrical Needs
Industrial and commercial facilities are extremely reliant on electrical power.
