Innovative Solutions For Power Generation In Zimbabwe

As Zimbabwe experiences power shortages, the solution lies in the adaptation of renewable energy. There are several sources of renewable power such as solar, thermal, hydro, wind and gas that can be used as an alternative. Notable is the Honde Valley district, whose power, through the mini-grid system, takes advantage of abundant

water in that part of the country. The district has several mini-grid schemes that have changed the lives of residents in the area. Nyangani Renewable Energy (NRE) is a prominent player in the generation of renewable energy in Honde Valley.

NRE’s innovative approach has seen the national grid

being supplemented and better access to reliable electricity has been recorded. This includes every local school being connected to consistent power and rural development goals are being achieved.

Recent reports say that the NRE initiative generates more than 30 megawatts

(MW) that goes to easing the national challenge. The Honde Valley scheme is a good example of how Zimbabwe can deal with the ongoing power crisis. Though costly, private investment is key to scaling up and accelerating the deployment of renewable energy minigrids.

The

Mini-Grid Market Opportunity Assessment Report for Zimbabwe (December 2018) says that there were about 25 IPPs (Independent Power Producers) that have been licenced, and whose projects were still to be implemented. The report further stated: “IPPs have faced significant barriers to participating in the power sector due to lack of clarity over-regulation and a lack of incentives, together with a high offtake risk for

independent generators. Given the anticipated surge in demand for electricity, consistent with the growth trajectory expected under the new economic dispensation, investment in power generation projects such as small hydro and solar plants has been recognised by Government as critical.” Zimbabwe recently unveiled the Renewable Energy Policy that is expected to help IPPs manage the above-mentioned obstacles.

Local and international organisations participating in remote small hydropower schemes have the potential to boost the interest of independent players towards the expansion of IPPs connected to the national grid. More players ranging from policymakers to developers are demonstrating a willingness to work towards achieving hydropower efficiency.

Mini-grids hold great potential to boost electricity access,

power households, key social services such as health centres and schools, and businesses, driving economic growth. UNDP modelling estimates that mini-grids will be the lowest-cost approach to bring electricity to 265 million people in 21 countries including Liberia, Benin, Burkina Faso, Chad, DR Congo, Ethiopia, Mali, Mauritania, Niger, Nigeria, Eswatini and Sudan by the year 2030.

$65 billion in new investments, primarily from the private sector, would be needed to realise the mini-grid opportunity in certain parts of Africa. This is estimated to equate to the construction of 110,000 mini-grids, bringing electricity to more than 200,000 schools and clinics, and more than 900,000 businesses.

Historically, there have been some innovative power solutions in Zimbabwe, notably championed by the award-winning bio-ecological development proponent and innovative designer of Harare’s iconic Eastgate Centre, Mick Pearce, who said in an online interview: “The only form of energy which does not run out is the sun, and it is delivered

to everywhere in Zimbabwe, so if you can harvest it during the day, you can do that on rooftops where it is needed. This saves transmission costs and energy losses (sometimes as much as 30%). The other huge advantage is speed. PV panels and the gear including batteries can be placed in the shortest time of all other sources of power production.

Batteries are a big expense and an absolute necessity. We should be following the exciting news about alternatives to lithium ion and there are many being invented; like the arms race in the 70’s. With rooftop power stations, we need to follow the example of countries like Bangladesh where they have mini-grids.

Each mini-power station is interconnected so they have in the delta region, moved away from centralised power production to mini-grid networks. This saves storage and therefore batteries. Once you have a mini-grid in which most people are producers and every form of power generation can feed into it you can begin to achieve continuous power supply. In Zimbabwe, we have enough

power at night but not nearly enough power during the day. This means we need to go for the solar big time”, he said.

Energy and Power Insider magazine also spoke to Francis Xavier Chitanda, the founder and CEO of Intergas, a specialist in off-grid energy and part of Intercontinent Energy, who are committed to improving how energy is distributed and consumed

in Africa. Chitanda spent a good part of his career as an accountant in the financial services industry working in the UK, Cayman Islands, Hong Kong and Singapore. Upon returning home in 2016 he decided to quit his finance career to start Intergas which focuses on energy innovation centred on gas as a key driver of clean and reliable energy provision. Intergas has worked with SAZ and ZERA to

champion the adoption of new energy technologies.

We spoke to Chitanda for more insight.

Zimbabwe is currently experiencing power shortages. What alternative power solutions do you recommend?

Indeed, it is a fact that the country is in a dire power crisis for some reasons, which are

well documented. It is thus quite clear that, as a nation, we need to prioritise the adoption of captive power solutions particularly targeted towards high consumption sectors of the economy such as manufacturing and mining. We must start exploring the right mix of energy sources to produce sustainable power supplies. In addition, a mindset shift by corporate decision-makers would be helpful. Practices

such as private importation of power (via the ZETDC infrastructure) may not be sustainable for the nation. Homegrown and sustainable solutions are the only way forward.

A hybrid solution mixing renewable photovoltaic (“PV”) plants and “Gas to Power” could be a viable option. Solar PV is a cost-effective way of producing power. However, the cost of power storage when

the sun is no longer shining can be expensive. To mitigate this, a hybrid solution could be utilised, whereby adding a micro gas turbine to the Solar PV plant would support the power generation process for the night hours and rainy seasons. Our calculations show that gas-fired turbines using Liquefied Petroleum Gas (LPG) could reduce the cost of power by 30 to 45 per cent, compared to using diesel generators. To enhance this

cost reduction even further, LPG could be replaced by cheaper forms of gas such as Biogas or Liquefied Natural Gas (LNG). Biogas can easily be produced using biodigestors from local animal farm waste and food waste. The gas turbines can range in capacity from 65kva upwards and do not have the weaknesses that diesel generators have, such as needing regular maintenance and daily downtime.

A gas turbine can operate non-stop and requires very little maintenance. Tariff for gas-produced electricity starts from 16c per kWh upwards depending on the quantum of power produced. A mix of the gas power tariff with the cheaper renewables tariff will bring down the average cost of electricity to approximately 15c per kWh. Although the captive power solutions will cost more than the heavily subsidised ZETDC electricity, they will be a more reliable and sustainable source of power. Investment in this solution is readily available subject to terms and conditions. If the heavy consumers of power in the economy adopt the captive solutions, which have

fewer regulatory and licencing requirements and the grid will have enough capacity for essential services like hospitals, schools and households.

Tell us how alternative power solutions are helping residential areas.

For our customers in the residential sector, we have been successfully able to diversify the energy mix between electricity and gas. You will find that the biggest uses of electricity in a home are cooking and water heating. We have put these on LPG by installing gas geysers and gas stoves. At Aspindale Park our customers are not affected as much by the power

cuts because the residual household appliances such as entertainment systems, lighting and fridge are covered by the solar system. This also reduces the need for households to invest in big solar systems which are currently unaffordable for many. We have efficiently managed to implement this system on larger residential developments through the introduction of metered estates which use LPG sourced from a communal gas tank shared by a cluster of houses piped through smart meters to monitor usage and facilitate payments. The smart meters are similar, in technology, to those deployed by ZETDC for electricity.

This has made gas conveniently available and households use mobile money to purchase gas at any time through their smart meters rather than having to go outside their homes carrying heavy cylinders to look for gas. Our customers at Aspindale Park and other developments have benefited greatly from the convenience provided to them through this system.

You were the first to introduce a gas-powered car in Zimbabwe. Tell us the benefits of this type of car.

Autogas is a term used for LPG use in the automotive industry to power automotive

engines. The Autogas technology has been around for close to a century now with the first conversion having been done in 1939 by Italian automotive giant, Tatarini Auto. The technology has improved tremendously over the years with over 25 million vehicles worldwide currently running on Autogas. Autogas comes with numerous benefits for Zimbabwe, from an economic as well as an environmental perspective

with significant savings accruing to fleet and vehicle owners.

As a form of fuel, Autogas is very safe and reliable. In Zimbabwe, the safety of any form of fuel is seen by its eventual adoption for household use. Take for instance paraffin which was and still is being used for cooking at the household level. The same can be said about gas today with most

urban households now moving towards having gas stoves, lighters, water heaters, space heaters and even gas fireplaces in homes. This is evidence that the general population is getting more comfortable with the domestic use of gas. Autogas is a safer fuel compared to petrol when used properly. This is because petrol is more volatile, with an ignition point of 246 Degrees Celsius compared to that of LPG at 470 Degrees Celsius.

What this means is, petrol is more likely to cause a fire than gas. Autogas is a huge cost saver. It can save a petrol engine user 50% of their fuel bill and 35% for a diesel engine vehicle.

Imagine the cost-saving impact for the transport industry particularly for long haul fleet managers, taxi companies etc.

Return of investment for converting a vehicle to Autogas can be realised in 3 to 8 months, but savings are realised immediately from the date of conversion.

What are the challenges to implementing these innovative energy solutions?

The biggest challenge we face is the customer’s perception of gas as being dangerous. We, however, have been fortunate enough to have a regulator (ZERA) that supports innovation. 4 years ago, when we started our company, Intergas, there were no regulations for the adoption of captive power solutions above 100kva but now these regulations exist, thanks to the support of ZERA. In addition, there was no regulation on the implementation of LPG microgrids but now we have a standard and a law that will be implemented soon. The law even covers how to regulate retro-fitting gas microgrids into existing homes and buildings. Autogas was unheard of but now there is interest across the board from public and private players keen on considering it for the fuel cost-saving benefit.

Another massive challenge we have is that our industry is capital intensive and it is currently very difficult to get the right type of long-term investment we need especially for an industry still in its infancy (“greenfield”). Setting up the distribution chain requires a huge investment. But this is doable, as the legal and regulatory environment has improved greatly over the last 4 years, thanks to ZERA’s stance on the adoption of new technologies to enhance our energy mix.

Encouraging state of green economy investment and development in Zimbabwe

Text by Martin Chemhere

The path towards a green economy in Zimbabwe is becoming clearer with the proliferation of renewable energy projects across the country that answer to the global climate emergency. The situation at the national level is so dire that all stakeholders must consider going the extra mile to protect the country and the planet’s future. The good thing is that the benefits that will accrue from

achieving a green economy will be clear and visible. Investment in the green economy has the power to turn around Zimbabwe’s ills such as the provision of jobs and improved and sustainable commercial activities, among others.

While the target of a net zero global atmosphere by 2050 is still a long shot, it is the responsibility of the

Zimbabwean government alongside private sector players and other stakeholders to keep galvanizing for a strong green energy foundation. Recently, Zimbabwe unveiled a renewable energy policy, a welcome gesture that helped to portray the country as a progressive player in upscaling the adoption of alternative sources of energy and therefore setting the tone for the sound building of a green economy.

A green economy success in Zimbabwe hinges on the strong will of the government, hence the renewable energy policy can be described as a boon for sustainable futures for all.

We have already seen in the last few years the emergence of new projects across the country, initiated by local, regional, and international companies.

Among the projects is the proposed 1,000-megawatt floating solar farm on Kariba Dam which is the biggest green energy project in Zimbabwe ever. Managed by the Chinese, it is expected to have a huge impact on Zimbabwe’s efforts to transition from fossil fuels to renewable sources. China Energy Engineering Corp

is behind the Kariba Dam initiative.

Outside Harare in Nyabira is another project where Centragrid Energy Systems Africa PV solar power plant is being increased from 2.5 MW to 25 MW. The $21.5 million investment is spearheaded by African financial services powerhouse Old Mutual,

through its Old Mutual Investment Group Zimbabwe. Centragrid Private Limited, an independent power producer (IPP) is the developer and operator of the Nyabira solar power plant. The solar plant further attests to the will of local companies to respond to the government’s call for an all-inclusive push for green

energy sustainability.

Another project involves Total Eren, in a venture with Chariot, who will develop, finance, construct and operate a 30 MWp solar photovoltaic (PV) project in Mashonaland West, generating clean energy for Karo Platinum Mine.

The several reasons why Zimbabwe needs a green energy revolution include the need to provide solutions to perennial power shortages as a result of redundant coal power stations, and an overloaded national grid. Commercial activities are also being curtailed due to constant blackouts.

As a developing country, Zimbabwe has been courting the buy-in from global development partners as it looks for solutions that will pull it out of the current and ongoing electricity deficit. This makes the current state of the green economy investment and development very encouraging.

Advancing Renewable Energy Access in Zimbabwe: Powering Sustainable Development

Zimbabwe, with its installed capacity of 2500MW, currently faces a significant shortfall in electricity production, generating only 1105MW. This deficit has resulted in load shedding, causing disruptions in daily life and impacting various sectors of the economy. However, this challenge has also propelled the country towards embracing renewable energy sources to ensure a more reliable and sustainable power supply. By

recognizing the importance of power security, Zimbabwe has not only benefited individually but also contributed to global efforts to combat climate change and achieve the Sustainable Development Goals (SDGs).

Addressing Power Shortfalls and Load Shedding

Zimbabwe’s struggle with electricity shortages and load shedding has highlighted the need for alternative energy sources.

Reducing Greenhouse Gas Emissions

In response to this energy crisis, the adoption of renewable energy solutions has gained traction. Solar and wind energy, in particular, have emerged as viable options to augment the traditional power grid. Solar panels and wind turbines are being installed in homes, commercial establishments, and industries across the country, offering a decentralized and sustainable energy supply.

Zimbabwe’s commitment to the Paris Agreement demonstrates its recognition of the urgent need to address greenhouse gas (GHG) emissions. By transitioning towards renewable energy sources, the country can significantly reduce its carbon footprint. Unlike conventional energy generation, which relies heavily on fossil fuels, renewable energy technologies produce minimal to no greenhouse gas emissions during operation. This shift contributes to mitigating climate change, improving air quality, and protecting the environment.

Global Goals for Sustainable Development

The transition to renewable energy aligns Zimbabwe with the Global Goals for Sustainable Development, as outlined by the United Nations. These goals encompass a wide range of objectives, including affordable and clean energy (Goal 7), climate action (Goal 13), and sustainable cities and communities (Goal 11), among others. By promoting renewable energy access, Zimbabwe contributes to the global efforts of achieving

these goals. The adoption of clean energy technologies not only addresses the energy needs of the country but also supports sustainable development in various sectors, such as agriculture, healthcare, and education.

A Lucrative Market for Renewable Energy

Zimbabwe’s increasing reliance on solar and wind energy has created a lucrative market in the residential, commercial, and industrial sectors. The rising demand for renewable energy solutions has led

Zimbabwe’s recognition of the importance of power security and the subsequent adoption of renewable energy sources demonstrate the country’s commitment to sustainable development and global climate goals. By harnessing solar and wind energy, Zimbabwe aims to address its electricity shortfall, reduce greenhouse gas emissions, and improve energy access for its citizens. This transition to renewable

to the growth of businesses specializing in the installation and maintenance of solar panels, wind turbines, and associated energy storage systems. This emerging market offers opportunities for job creation, entrepreneurship, and economic growth. Moreover, increased access to renewable energy empowers individuals and businesses with a more reliable and cost- effective source of electricity, reducing dependence on the national grid and mitigating the impact of load shedding.

energy not only benefits the country individually but also contributes to the global efforts of achieving a sustainable and clean energy future. As Zimbabwe continues to expand its renewable energy sector, it paves the way for economic growth, job creation, and a more resilient and environmentally conscious society.

Understanding Your Electrical Cables

Electrical cables transport electrical energy from one point to another. A cable is an assembly of one or more electrically conducting wires which is used to carry electric current. Electricity travels along some materials more easily than others and materials are divided into conductors and insulators.

Components of Electrical Cable

1. Conductors: are the electricity transmitting wires in a cable. These are made from high conducting metals like Copper and Aluminium which have low resistance.

2. Insulators: are bad conductors of electricity, insulators do not allow electricity to pass through them.

In earlier times, paper, cloth, or rubber were used as insulating materials. However, these are now replaced with different synthetic polymers such as Polyvinyl Chloride(PVC), Polyethylene, and Butyl Rubber.

The conductors, usually copper wires, are covered with insulating material to prevent contact with each other, or with any external conducting materials. Insulation varies in thickness Wamount of current they have to carry: the greater the current, the thicker the conductor.

3. Cable metal protection: In some cases the cables may have metal protections. Electrical metal shields (screens) are applied to isolate the signals that pass through the interior of the cable from possible external interference.

Mechanical protection (armours) protect the cable from possible external aggressions and damage.

4. Outer Sheath: The function of this outer insulator jacket is eminently protection. The sheath protects the cable from atmospheric conditions like high moisture in the air, chemical reactions, or fire attacks. Commonly used sheaths are made from polyvinyl chloride (PVC).

Classes of Electrical Cable

Electrical cables are broadly classified by voltage:

• Low voltage cables (up to 500 V):

• Low Voltage cables (up to 1,000 V): (also called (0,6/1 kV) The cables in this section are used for industrial power installations in various fields (general industry, public installations, infrastructures, etc.).

• Medium Voltage cables: from 3.3 kV to 22 kV. They are used to distribute electricity from electrical substations to transformer stations.

• High Voltage cables: from 33 kV. They are used to transport electricity from the generating plants to the electrical substations.

Types of electric cables by their application

Cables for electric panels: Flexible cables for wiring electric cabinets. These electric cables are especially suitable for domestic use, for installation in public places and for internal wiring of electrical cabinets, switch boxes and small electrical appliances.

Power cables: Energy cables for industrial facilities and public places. It is common to find power cables in applications for power transmission in all types of low voltage connections, for industrial use and for variable frequency drive.

Armoured cables: Cables with aluminium or steel reinforcement for installations with risk of mechanical aggression. It is also common to find armoured cables in places where rodents are present, as well as in installations in premises with a risk of fire and explosion.

Rubber cables: The use of extra flexible rubber cables is very varied. We can find rubber cables in fixed industrial installations as well as in mobile service. Welding cables should have a rubber sheath, which allows high currents to be transmitted between the welding generator and the electrode.

Control cables: Control cables for fixed or mobile installations should be extremely flexible, as they are mainly designed for small household appliances, for the interconnection of machine parts used for manufacturing, for signalling and control systems, for the connection of motors or frequency converters, for signal transmission where the voltage induced by an external electromagnetic field may affect the transmitted signal or for power supply connections to avoid generating electromagnetic fields.

Halogen-free cables: Low Halogen Cables with low smoke and corrosive gas emission in case of fire are suitable for use in wiring of electrical panels and public places, installations of all kinds in public places, individual derivations, emergency circuits, public distribution networks and also for mobile service.

Instrumentation cables: These are flexible and shielded cables for the transmission of signals between equipment in industrial installations. Especially suitable for optimum data transmission in environments with a high level of electromagnetic interference.

Flame retardant cables: These cables are specially designed to transmit electrical energy in the extreme conditions that occur during a prolonged fire, guaranteeing supply to emergency equipment such as signalling, smoke extractors, acoustic alarms, water pumps, etc. Their use is recommended in emergency circuits in places with public concurrence.

Solar cables: These cables are particularly suitable for connecting photovoltaic panels, and from the panels to the DC to AC inverter. Thanks to the design of their materials and their cover, which is especially resistant to solar radiation and extreme temperatures, they can be installed outdoors with full guarantees.

Aluminium Overhead Conductors: Bare or insulated Aluminium conductors are suitable for transmission and distribution lines.

Types of colours in electrical cables and their meaning:

The colours of the electrical cables are governed by the International Electrical Commission Standard IEC 60446. For the identification of the conductors, the following colours are allowed: black, brown, red, orange, yellow, green, blue, violet, gray, white, pink and turquoise.

• Neutral conductor: blue. It is recommended not to use more blue conductors to avoid confusion.

• Phase conductor: black, grey or brown.

• Protective or earthing conductor: two colours, yellow and green.

Importance of Standards in the manufacture of cables

The Zimbabwean cable manufacturer satisfies the International Electrical Commission requirements by accreditation to ISO 9001 though Standards Association of Zimbabwe (SAZ) and South African Bureau of Standards (SABS).

Adherence to standards ensures quality and safety of cables.

• The local manufacturer was the first Zimbabwean entity to gain accreditation to ISO 9001:2015 Quality Management Standard in 1993.

• Environmental Management Standard ISO 14001:2015 –First Zimbabwean company to be accredited in 1999

• Occupational Health and Safety Standard ISO 45001:2018 –Accredited in 2009

• Energy Management Standard ISO 50001:2018 –First Company in Sub-Saharan Africa to gain accreditation in 1026

To avoid purchasing and installing sub-standard or smuggled cables and for recommended technical advice, buy all your cable requirements directly from the local manufacturer.

Gasman Pvt Limited:

Newly Established Gas Company Finds Its Perfect Fit In Harare

There are many signs of growth in the Zimbabwean renewable energy sector, with vast opportunities being offered to new players. In anticipation of competitive performance, new players like Gasman Pvt Limited have entered market with adequate preparation to make a mark.

Established in February this year and currently operating from 15 Lorely Close, Msasa, in Harare, the new kid on the block’s services includes importing, distributing, and delivering, as well as

wholesaling and retailing of LPG (liquefied petroleum gas). Presently, the business covers only the Harare and surrounding market, but it has the vision to focus on new areas soon. Though the company doesn’t currently supply gas accessories, they hope to commence this product line soon. This will see the provision of gas cylinders ranging in different sizes to the entire market for both domestic and commercial needs.

The company says dealing

in gas has enabled them to contribute to the Zimbabwean economy but noted that gas users, whether domestic or commercial, should always look out for any slight leak incidents that could lead to a disaster.

“All gas gadgets are prone to developing leaks over time. Most common gadgets use seals, valves, and gaskets and these get worn out with time. Examples of such gadgets are cylinders, cooker tops, hoses, and valves which are most prone to leaks. Regular

servicing and maintenance schedules are crucial for proper use and safety,” said Farai Hilton Mufandaedza, the site manager.

High regulation for the Zimbabwean energy and power industry means that the company prioritises registering with relevant organisations such as the Zimbabwe Energy Regulation Authority (ZERA), enabling them to carry out their work of installing gas equipment for commercial and domestic use.

“Registration is important as

it ensures that the proper accredited LPG professionals perform the installations according to the ZERA and Standards Association of Zimbabwe (SAZ) regulations and requirements. Not adhering to the regulations compromises the safety of the equipment and those using it. In addition to this, users should make sure that there are no naked flames or smoking near the cylinders or LPG storage areas in the home. And proper ventilation is accessible in the area. Tanks should never be kept in cupboards or enclosed areas. Cylinders, as much as possible, should be kept outside the home,” he said.

There are several other things to look at such as follows:

• Gas cylinders should always be upright in a vertical position with the valve on the top.

• Always install the tank at ground level so that the stove or heater is positioned higher than the gas tank.

• Don’t keep the tank exposed to rain, sun, dust and heat.

• Tanks should have longer pipes, to have a distance away from the heat or naked flame source.

• Use the correct hose and check it

regularly for cracks or leaks. If funds permit change rubber seals and hoses once every 12-24 months.

• Never use plastic as a substitute for thread tape or to tie hose, and rather call the professionals to ensure that the job is done right, and safety measures are attained.

Gasman Pvt Limited will attend to all LP Gas requirements through their experienced staff that has more than 5 years of experience in the LPG industry. The company also strives to keep up with new trends in the sector by researching and implementing what is happening in other parts of the world.

The site manager notes that reacting to a gas leak is key to the management of the risk, which will eventually lead to maintaining a good safety record for the company. The foremost step would be to first move the gas gadgets to a well-ventilated place and identify the source of the leak and find the best way to eliminate the leak. The best way to eliminate leaks is to redo the whole installation using new thread tapes, a new hose, or even a new gas cylinder/ tank if you feel that is the source of the leak. Please ensure you contact the correct personnel for the job.

Gasman Pvt Limited offers retail and wholesale of LP Gas, and bulk deliveries within Zimbabwe from 500kgs to 2 tonnes per load. So, far they have 2 branches, one in Msasa and one at the Aspindale Truck Stop.

The company is a member of ZERA and advises that it is important to be registered to install gas equipment for industrial and domestic use. This requires company personnel to be trained and qualified, all the safety precautions for handling and storage of LPGas equipment according to ZERA and Standards

Association requirements. In the end, the community will be safe from explosions or gasrelated accidents.

Adhering to ZERA standards means the following:

ZERA - Things to do:

• Use ZERA trained, accredited and qualified LPG professionals in the industry with good experience and knowledge.

• Use gas cylinders/tanks which comply with Standard Association of Zimbabwe (SAZ) SANS10019.

• Handling and Storage Precautions of LPG tanks should always be observed.

• Observe all the LPG standards as mentioned by ZERA; that is location, design and control of filling of LPG.

• Use certified filling equipment if you are a Retailer or Wholesaler.

Gasman Pvt Limited stays relevant by reliably supplying premium products to customers, as well as ensuring professional services. Most of their products are supplied from South Africa, which is a major hub for regional and PanAfrican distribution.

Talking about challenges, the company experiences issues mostly around electricity, just like most companies in Zimbabwe. They note that the costs of running generators and solar products make it difficult to properly operate the business as effectively and costefficiently as they would like.

“Other than that, as a new company there are learning curves but we are confident of overcoming even the toughest of challenges that the industry may face,” said the site manager.

Frecon Solar has managed to carve a name for itself in a world desperately in need of clean technologies to reduce energy consumption and the waste of natural resources. Renewable energy

is seen as the solution for climate change, putting the environment, humanity, and economic security first to achieve sustainability. Initially starting in the informal trading sector in 2012 as Frecon

Electric, it was later registered in 2016 as Frecon Solar. The company is led by joint CEOs, Farai Mandinenga and Rebecca Musemwa, who oversee the Frecon Solar nationwide branches in

Belvedere (Harare), corner Samora Machel Avenue and Chinhoyi Street (Harare), Bulawayo, Karoi, Gweru, Mutare, Masvingo and Bindura.

At the core of their work ethic is the provision of excellent renewable energy solutions to satisfy the challenging needs of their diverse customers. Their vision is to supply quality products and give quality service locally, regionally, and internationally. Their mission is to grow into the

premier supplier of solar water pumping and borehole systems for industrial, household and agricultural use in the region in line with a policy of sustainability.

Since its formation it has completed many projects across the country in solar

water pumping systems, home borehole installations and consultancy. Steady growth has been achieved on the back of a buoyant solar energy industry and the robust support of sound technical management.

The company brings to the market a diverse range of products including solar lighting, solar heating, solar pumping systems and solar power systems (solar panels, batteries, inverters, water pumps, lights and more.)

The bulk of these products are sourced from India and have allowed the company to satisfy the needs of its diverse customers. The company is responding to the Renewable Energy Policy recently announced by the government of Zimbabwe.

The company supplies

individuals, corporates and farmers for solar water pumping systems. This delivery experience is anchored by high-end technology and the desire to satisfy increasing demand.

“We believe in technology; we have a group of young engineers who strive day

and night researching to come up with the most appropriate solution to meet the expectations of all Zimbabweans. We sell highend products and our prices are second to none,” said the CEOs.

The company currently employs more than 50 staff

and has plans to build at least four solar plants in Zimbabwe by 2030. Setting up of the plants will be dependent on the company receiving the license and land for the project from the government.

Zimbabwe to decommission small thermal stations

In a move that may see Zimbabwe generate more electricity in the future, the government recently called on ZESA Holdings to assess the efficacy and efficiency of some of the country’s small thermal power stations and find a more devise a comprehensive strategy with potential to move forward, considering all available possibilities, including that of decommissioning them.

It is widely believed that the three power stations at Harare, Munyati and Bulawayo, have been inefficient for a long time due their antiquated nature. Operation of the plants has also been at a huge cost to the electricity company, prompting calls for something drastic to be done.

Households and businesses start selling solar power to ZESA

In a new development that is set to ease power shortages in Zimbabwe, householders and businesses with solar power started selling their extra to Zesa Holdings. This move will enable those generating renewable energy to sell their surplus while they can also buy during the time when they need power from Zimbabwe Electricity Transmission and Distribution Company.

Oil, gas and helium found at Cabora

Bassa Basin

Invictus Energy on Monday 8 May confirmed the presence of light oil, gas-condensate and helium from its Mukuyu-1 mud gas compositional analysis. Results confirm multiple oil and gas pay zones in sandstone reservoirs consistent with wireline log interpretation.

The analysis shows that Upper Angwa reservoirs contain liquids rich gas with condensate-gas-ratio (CGR) estimated between 30 to 135 bbls/ MMscf, high quality gas with minimal CO2 content of less than 1% and

helium content consistent with global commercial helium producers.

Results confirm multiple oil and gas pay zones in sandstone reservoirs consistent with wireline log interpretation and fluorescence observed in sidewall cores and cuttings. There are also multiple source / reservoir / seal pairs through the Upper Angwa.

Invictus Energy Limited owns 80% of the Cabora Bassa Project in Zimbabwe.

SA expects to end load-shedding by 2024!

By this time next year, South Africa could have done away with electricity challenges, if the promises by the South African Department of Mineral Resources and Energy are anything to go by.

This means the current load-shedding that has affected the entire country will be a thing of the past. The somewhat ambitious target, involves the creation of favourable conditions that promote acceptable and significant use of solar photovoltaic (PV) energy. Acting DG of the Department of

Mineral Resources and Energy, Mthokozisi Mpofu, revealed the plans in her keynote address at the Solar Power Africa Conference 2023, in Cape Town, recently.

She said that the South African government had solutions to the current energy challenges, especially as the government expected the sound growth of the global renewable energy industry to make an impact to the value chain of the economy.

Boost for Zim as Invictus raises funds for next phases of work

Zimbabwe has received a big boost following Australian company Invictus Energy’s successful raise of A$10 million for the subsequent stages of its work in the Cabora Bassa Basin.

Availability of the funds is welcome for the company which plans to further build up

on the previous work growth with several ongoing phased out developments.

The current month of May will see the commencement of 2D seismic acquisition, and this will include the eastern part of EPO 1848 and 1849. It is expected that the new seismic will, among other things, see several

leads maturing to the east of Mukuyu. The early part of the third quarter of the year has been earmarked for the drilling of the Mukuyu-2. Another area that is being worked is the appraisal well.

Sichel Energies

Text by Perry Kaande

The town of Kadoma is being driven into the future with the opening of a new petroleum fuels provision facility Sichel

Energies. The service station began operations on 12 November 2022 and the company hints that after the success of this

pilot service station, there are plans underway to open more outlets. Sichel Energies is located in a

town that is a thoroughfare for vehicular traffic between Zimbabwe’s major towns and cities on the HarareBulawayo route.

Its proximity to the Ngezi turn off positions it to adequately service the mining and farming communities in the area. 60 percent of traffic that comes to Sichel energies is vehicular, while 40 percent is walk in customers from adjacent communities like Rimuka and people frequenting businesses such as First Capital Bank and large retailers such as OK and TM Pick n Pay as well as the Kadoma Hotel and Conference Centre.

When Sichel Energies began operations the pace was slow but potent with promise and now business is brisk.

“We have gained popularity over the months and with the passing of each day traffic is improving and God willing, numbers will treble considering how strategically located we are and how consistent we have been,” the company reveals.

Sichel Energies provides petrol and diesel in bulk for commercial and domestic use. The enterprise prides itself in the ability to supply fleets, company staff and the general public “with regular stock directly through our own service stations or delivered to your place of business”.

The petroleum provider also supplies liquefied petroleum gas (LPG) at both retail and wholesale prices. Currently Sichel Energies is not selling

gas cylinders, but is hoping to venture into the project once modalities are in place.

There is also scope for entering the renewable energy sector, namely solar. The company highlights that it is weighing the pros and cons “to ensure once we are in it, we will never go wrong.” At present, the service station has a solar instillation at the service station as the basis for a feasibility study.

They have upped the game in the service sector. When you are on a long journey or just need the convenience of getting a beverage and snacks or shop for your pantry, just walk into the Sichel Energies Kiosk that has an assortment of grocery items. On-sight there is a Technology Shop, where you can purchase ICT products such as mobile phones and related accessories. So if you forgot your phone charger or decide to purchase new gadgets while in transit just step into the store and make your selection. What Energy and Power Insider especially likes about the tech store is that the products are also available at wholesale price.

There are other personalised services as you fill up your vehicles. These range from simple window cleaning, car wash and oil checks as well as tyre pressure. You also do not have to worry about your vehicle being either crammed or rammed as there is ample parking space at the fuel pumps and around the forecourt.

The most important thing that you wish for when you are on the road is the ‘lavatory’. The fuel stop has world class ablution facilities, thus you are assured of stepping into a totally hygienic environment that has sparkling and fresh amenities.

For all your petroleum products requirements and extra services call 0779877001 and 0779877171 or simply drive to 6179 Josiah Tongogara, (Kadoma). If you want to go the digital route send your requests to info@sichelenergies.co.zw.
