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.

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.

Feds admit offshore wind can kill whales! — Watts Up With That?

Of course these admissions are well hidden, buried in the depths of thousand page documents Feds admit offshore wind can kill whales! — Watts Up With That?

[reasonsforhope]

"It is 70 years since AT&T’s Bell Labs unveiled a new technology for turning sunlight into power. The phone company hoped it could replace the batteries that run equipment in out-of-the-way places. It also realised that powering devices with light alone showed how science could make the future seem wonderful; hence a press event at which sunshine kept a toy Ferris wheel spinning round and round.

Today solar power is long past the toy phase. Panels now occupy an area around half that of Wales, and this year they will provide the world with about 6% of its electricity—which is almost three times as much electrical energy as America consumed back in 1954. Yet this historic growth is only the second-most-remarkable thing about the rise of solar power. The most remarkable is that it is nowhere near over.

To call solar power’s rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the world’s entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.

Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s. By the 2040s they may be the largest source not just of electricity but of all energy. On current trends, the all-in cost of the electricity they produce promises to be less than half as expensive as the cheapest available today. This will not stop climate change, but could slow it a lot faster. Much of the world—including Africa, where 600m people still cannot light their homes—will begin to feel energy-rich. That feeling will be a new and transformational one for humankind.

To grasp that this is not some environmentalist fever dream, consider solar economics. As the cumulative production of a manufactured good increases, costs go down. As costs go down, demand goes up. As demand goes up, production increases—and costs go down further. This cannot go on for ever; production, demand or both always become constrained. In earlier energy transitions—from wood to coal, coal to oil or oil to gas—the efficiency of extraction grew, but it was eventually offset by the cost of finding ever more fuel.

As our essay this week explains, solar power faces no such constraint. The resources needed to produce solar cells and plant them on solar farms are silicon-rich sand, sunny places and human ingenuity, all three of which are abundant. Making cells also takes energy, but solar power is fast making that abundant, too. As for demand, it is both huge and elastic—if you make electricity cheaper, people will find uses for it. The result is that, in contrast to earlier energy sources, solar power has routinely become cheaper and will continue to do so.

Other constraints do exist. Given people’s proclivity for living outside daylight hours, solar power needs to be complemented with storage and supplemented by other technologies. Heavy industry and aviation and freight have been hard to electrify. Fortunately, these problems may be solved as batteries and fuels created by electrolysis gradually become cheaper...

The aim should be for the virtuous circle of solar-power production to turn as fast as possible. That is because it offers the prize of cheaper energy. The benefits start with a boost to productivity. Anything that people use energy for today will cost less—and that includes pretty much everything. Then come the things cheap energy will make possible. People who could never afford to will start lighting their houses or driving a car. Cheap energy can purify water, and even desalinate it. It can drive the hungry machinery of artificial intelligence. It can make billions of homes and offices more bearable in summers that will, for decades to come, be getting hotter.

But it is the things that nobody has yet thought of that will be most consequential. In its radical abundance, cheaper energy will free the imagination, setting tiny Ferris wheels of the mind spinning with excitement and new possibilities.

This week marks the summer solstice in the northern hemisphere. The Sun rising to its highest point in the sky will in decades to come shine down on a world where nobody need go without the blessings of electricity and where the access to energy invigorates all those it touches."
