Three ways to future proof your business in light of COVID-19

We are now into our third month of lockdown, and are starting to see the widespread economic impact of the COVID 19 pandemic. In South Africa, lockdown restrictions have eased a little, with most sectors returning to work and strict health protocols in place. However, we are far from where we were at the beginning of March, when COVID 19 seemed only like a remote possibility. It now seems like we might be entering the worst economic recession since the Second World War. In light of this, how will businesses prepare for the already uncertain future?

A recession worse than last year

According to the South African Reserve Bank, the South African economy  is expected to contract by 7% in 2020. Many sectors have been hard hit, with sectors such as manufacturing being particularly affected. Manufacturing itself was already struggling before the pandemic hit:  in February it reported a 2.1% year-on-year decrease in production volumes. The loss of production during the lockdown has further slowed some manufacturing sectors, such as the automotive industry, making their future uncertain. 

The struggling sectors, combined with the the fact that many South African’s have lost their jobs and will be spending little in the economy. Initial research shows that up to 14% of South African consumers have lost their jobs, with a further 37% saying that their work hours have been reduced. Many of them will be forced to cut expenditures dramatically in order to make ends meet, further shrinking the economy.

Since a recession seems inevitable, how can businesses weather the storm? The following are three suggestions. 

  1. Look critically at your business strategy

Those businesses that are flexible in either their operations or their offering will be the most likely to survive economic recession. We’ve seen this first hand: the closure of businesses that were successful but unable to adapt to the lockdown situation, and the success of businesses that make the most of the opportunity. Because no one saw this coming, it is those businesses that quickly adapted that got this aspect right. 

During a recession, essential, basic-needs items remain, whilst luxury, non-essential items are prioritised less by consumers. Pivoting your business strategy in order to meet the needs of consumers is important. In a business that focuses on industrial manufacturing, see if there are opportunities for operational efficiencies, such as making a basic necessity from the by-product of an industrial process, such as South African Breweries changing their manufacturing processes during the nationwide alcohol ban to produce much-needed hand sanitizer.

Rethinking business strategy is important for remaining profitable during a recession
  1. Cut operational expenditure

Cash flow is an essential to surviving a recession, and the reason that even profitable companies go under: without the cash to pay off operating expenses or salaries, businesses can quickly become bankrupt. One way to cut expenses, before the difficult decisions to retrench staff members, is to start with operational costs. In manufacturing and other industries, the easiest way to cut these expenses is to look to utilities – electricity and water – to ensure they are not spending more than necessary on these items. 

Start by evaluating the business for any potential inefficiencies: is it possible to shift production slightly later, to avoid peak hours? Can you implement a staggered start up of the plant, to avoid kVA surges and the associated costs? Have you made sure that energy inefficient lighting and heating have been taken care of? Once these factors have been examined, it is easier to identify how to proceed with reducing operating costs. 

One way that is very helpful to cut operating costs is through procuring solar PV electricity through a Power Purchase Agreement or PPA. This allows your business to benefit from lower electricity tariffs during the sunlight hours, and can be particularly beneficial if you can shift the bulk of production to happen during the day when the sun is shining. The one great thing about solar PV is that, even in the context of a global recession, prices are predicted to continue rapidly dropping.  

  1. Make sure your staff are engaged

Although there has been much written about employee engagement over the last few years, this “buzzword” does translate to the bottom line. A study conducted globally found that companies with highly engaged staff members had 17 % returns than those with low engagement levels. Therefore, in a recession where the bottom line is under threat, ensuring that employees are engaged could have a significant financial impact. (This also translates to employee turnover, by the way – about 40% of employees at low-engagement firms were likely to be looking elsewhere for jobs).

So how do companies create high employee engagement? This goes beyond basic employee wellness interventions, and translates back to genuine employer-employee value. If your employees believe that you are genuine about investing in them, they will be more likely to invest themselves in their job, which will translate into financial returns.

Removal of Power Constraints Crucial for Post COVID-19 Recovery

This article originally appeared in the Daily Maverick Opinion Section.

It is difficult to understand why the main limitations to private power generation have not been removed, despite repeated pledges from government to that effect. There is a real danger that while grappling with the immediate crisis, policymakers will shelve the issue indefinitely.

Demand for electricity has plunged with the onset of South Africa’s COVID-19 lockdown, removing the threat of load shedding for its three-week duration. It could be several months before the economy is up and running normally again, but it would be a big mistake to forget the power constraints which plagued SA in the weeks before the pandemic struck.

When Moody’s downgraded SA on 27 March, it pointed out that unreliable electricity supply and its impact on the economy was one of the main reasons for the decision. The ratings agency also pointed out that a strategy to stabilise electricity production in the country has failed to materialise and that as a result, economic growth would remain low for years. Returning to a constrained electricity supply without an adequate government response is the last thing embattled businesses need after COVID-19. 

Against this background, it is difficult to understand why the main limitations to private power generation have not been removed, despite repeated pledges from government to that effect. There is a real danger that while grappling with the immediate crisis, policymakers will shelve the issue indefinitely. In addition, the National Energy Regulator (NERSA) has inexplicably halted all new licensing applications for the duration of the lockdown period. 

For connected projects larger than 1MW — which applies to most of the pent-up demand for corporate generation of electricity — a license is still required from NERSA even if the installation is for a customer’s own use, or established through a bilateral agreement involving only a customer and an independent power producer.

These onerous license application processes were intended for large, utility style power stations, hundreds of MWs in size, and each requires a public participation process with hearings. They have requirements which make the development of smaller project impractical. The official time for NERSA to issue these licenses is 120 days but in practice it takes far longer — with some cases so far taking as long as two years.

NERSA is theoretically able to process license applications, but in practice is inadequately resourced to handle the quantity of smaller applications that are now being made. This regulatory blockage is holding up the roll out of hundreds of MWs of electricity generation, which would be the fastest way to alleviate the power constraints which lead to load shedding. 

This point has been repeatedly made by independent bodies like the Minerals Council of SA, Business Unity SA, the South African Photovoltaic Industry Association, and the Council for Scientific and Industrial Research. It has been recognised by Minerals and Energy Minister Gwede Mantashe, who indicated at the mining Indaba in March 2020 that self-generation of any size would not require licensing. 

Companies in the private sector were hopeful that their pleas for the 1MW cap on licensing for their own electricity generation would be lifted to 10MW, which would include most of the projects they want to implement. And yet, when the eagerly awaited Schedule 2 of the Electricity Regulation Act was published on 26 March, the 1MW threshold for grid-connected facilities exempt from licensing was maintained. 

The shape of the national load profile – when and how much electricity is used – is important to Government because it affects which mix of electricity is most cost effective. Its preferable to have a load profile that allows for the maximum usage of the cheapest resources available to the country. From this angle, the control over who builds what generation is understandable, but even with this argument considered, the amount of solar power in South Africa still represents under 5% of installed capacity, and less than 2% of the consumed energy.

A 10MW solar generator represents 0.006% of annual electricity demand and 150 of such projects would need to be installed to reach 1% of the total demand. Lifting the license exemption threshold to 10MW will initially have negligible effect on the demand profile but a huge effect on lifting red tape in the way of more energy coming onstream and supporting small to medium size businesses. It is always possible for the state to monitor the uptake and lower the threshold for licences at a later stage if necessary.

As the chairperson of a solar PV company, the SOLA Group, I have seen many clients desperate to install larger solar plants than the 1 MVA limit to alleviate their electricity constraints and lower their costs. These projects are practically ready to be rolled out – and could be built within 8-12 months – if the licensing hurdle is removed. 

From my extensive experience in the solar PV industry in South Africa I estimate that, without such restrictions, solar PV companies could build 500 MWs within the next 12 – 18 months. The wasted opportunity due to these arbitrary licence requirements is obvious and destructive.

For the sake of saving businesses and creating jobs post COVID-19, I urge government to:

  • Lift the threshold on requirement for a generation license from 1MW to 10MW until the embedded generation allocation in SA’s new Integrated Resource Plan has been reached.
  • Require that these projects are registered with NERSA upon their commercial operation date through submission of an independent certificate of compliance against which the allocation to embedded generation can be measured, and keep the database of installed MWs public and updated.
  • Ensure that NERSA is provided with, or creates, clear guidelines as to the technical standards that must be met to obtain a generation license for generation projects above 10MW in size.
  • Provide NERSA with the resources, both through budget and staff, to evaluate the applications in a meaningful, prompt and scientific way.
  • Return to processing and receiving licence applications during the lockdown.

The business case for installing embedded power generation remains for the private sector, and the economy will once again start moving when the impact of the pandemic subsides. It would be tragic if its potential to recover is thwarted by continued electricity shortages.

AB InBev bolster breweries with 8.7 MW renewable energy from SOLA

Renewable energy solutions are a quick and efficient way for South Africa to reduce energy demand on Eskom’s constrained grid, and solutions are being supported by businesses who see the value of embedded electricity solutions for their supply chains. 

This is according to Chris Haw, Chairperson of the SOLA Group, who in 2018 signed seven multi-tiered Power Purchase Agreements (PPA) with AB InBev Africa that are seeing large solar power plants built across seven major breweries in South Africa.

The Power Purchase Agreements will total around 8.7 MW DC capacity. Of this, 2.6 MW have already reached practical completion with the remaining projects in advanced stages of construction.

“Not only is solar a viable and cost-effective option for us, it aligns to our global sustainability strategy, which entails going 100% renewable by 2025,” says Taryn Rosekilly, Vice President of Procurement and Sustainability at SAB and AB InBev Africa.

ABin Bev Breweries will now be powered with solar energy

The bold step taken by AB InBev Africa highlights the private sector’s strong drive towards reducing carbon emissions and procuring renewable energy solutions.

Gugulethu Nogaya, the Renewable Energy Procurement Manager at AB InBev Africa explains that “procuring renewable energy is part of our sustainability objectives set at a global level. Our global renewable energy commitment is to ensure that 50% of our purchased electricity will come from renewable energy sources by 2020, and 100% by 2025”. 

Nogaya points out that the company has achieved its 50 % target ahead of schedule. “We are currently on track to achieve our 100 % target, with the PPA being an instrumental first step in ensuring our African business is on track to achieve the 2025 ambition.”  

Nogaya adds that “in order to meet the AB InBev 100 % target in South Africa, it will require solar renewable energy facilities to the total of 191 MW.”

According to the International Energy Agency, distributed solar PV systems in homes and Commercial and Industrial buildings have almost tripled since 2014. It predicts that distributed energy will grow as much as onshore wind by 2024, making up half of all new solar PV capacity. 

This is likely due to the flexibility and affordability of PV plants compared to other forms of energy generation. The rollout of large-scale solar PV systems takes much less time than other generation technologies. 

There is also a greater demand and expectation that businesses take more responsibility for the way in which they operate. Providing renewable energy allows businesses to meet their sustainability targets whilst taking pressure off of Eskom’s load.

The PPA between AB InBev Africa and the SOLA Group is allowing solar PV to be rolled out without AB InBev incurring capital costs. Instead, the company will purchase its power requirement directly from SOLA, with the remainder coming from Eskom and local municipalities. 

In 2019, SOLA secured R400 M with partners from African Infrastructure Investment Managers (AIIM) and Nedbank in order to fund projects such as the AB InBev Africa solar facilities.

“Embedded electricity generation – particularly solar PV – can quickly address Eskom’s supply shortfall,” states Haw. “For large Commercial and Industrial companies, procuring renewable power enables saving costs whilst also reducing their carbon footprints.” 

The solar PV plants for AB InBev Africa span across seven different sites in various areas of the country, including the Western Cape, Limpopo, Gauteng, KwaZulu-Natal and the Eastern Cape. 

“Combined, the plants will consist of over 23 000 solar panels. The construction of the projects will create 175 jobs, in addition to SOLA’s 56 permanent positions,” points out Haw. 

AB InBev Africa is one of the largest industrial business in South Africa, making the conversion of their sites to solar significant. “The PV systems will produce close to 14 GWh of electricity per year – the equivalent of taking over 2000 cars off the roads. This is exactly the type of clean energy procurement that we need to see more companies committing to,” concludes Haw. 

Industrial solar installations – dos and don’ts for facilities managers

If you run an industrial facility you’ll be well aware of the benefits of grid-tied solar PV solutions. Running cheaper and more efficiently than utility-provided power (such as Eskom), solar PV provides substantial savings for industrial facilities as a source of reliable alternative power. However, there are many solar companies purporting the benefits of solar power, and not all facilities managers are able to discern the best option for their facility. The below guide highlights 5 dos and don’ts for facilities managers to ensure that the procurement of solar is an effortless one.

Do: Practice due diligence when procuring solar PV.

Procuring solar PV is a 25 year decision. If chosen correctly, solar PV can provide 25 years of affordable and clean energy to your industrial plant. As such, it is important that the procurement process is done thoroughly and due diligence is practiced. It can be easy to rush into buying solar – particularly when the savings look promising. However, practicing due diligence when procuring solar will pay off in the long run. Start by asking a few simple questions about the solar PV procurement.

  • What is the objective of the PV system? If you are using it to save money, are you looking to make operational savings through a Power Purchase Agreement, or add value to your building through acquiring a solar asset? Perhaps a bit of both?
  • If you are looking to buy a solar system outright, do you have sufficient finance to do this? Is a PPA a better option for your business?
  • What is your typical energy load, and how much of it occurs during the day? Setting up metering can really help in determining what the right sized solar PV system would look like. 
  • Where would you place the solar PV system? Although wheeling arrangements allow power to be generated in a remote solar PV facility, the majority of small-scale embedded generation (SSEG) occurs on site. Having either a stable roof or a suitable piece of land is an important consideration when writing up your request for solar quotation.

Do: Get a reputable company to carry out your industrial solar installation

The most important part of your decision will be based on getting a reputable company to build the industrial solar installation. This means choosing a company with a solid track record of solar projects, particularly in industrial facilities. The chosen company should be able to get good prices on high-quality solar components such as modules; design efficiently and thoroughly, and carry out construction safely and within the budget and timeline. 

If you’re opting for a solar PPA option – where you don’t own the solar PV facility but simply buy the energy that it generates – you’ll want to ensure that the company you choose has sufficient available finance to build and maintain the system. Making sure that the company has credentials to stick around for the full term of the PPA is important.  Make sure that the solar PV service provider can meet basic requirements, such as:

  • Design credentials. Does the company have the relevant design experience and credentials to effectively design a PV system for your site? 
  • Adherence to minimum standards. In South Africa, this includes adherence to all relevant SANS codes, and ensuring that items such as wind load calculations are carried out according to SANS standards
  • Compliance with Municipal and National electricity standards municipal/eskom standards, including carrying out the relevant application processes to ensure that the PV system is legally compliant (such as Small Scale Embedded Generation (SSEG) applications)
  • Ensuring that a Practicing Engineer (Pr. Eng) is able to sign off on the system design and construction, yield estimation accuracy, 
  • Qualified site supervision, and construction that complies with all Occupational Health and Safety standards

Do: Compare Apples with Apples

Getting comparative quotes is always recommended: it helps you to compare different solar PV companies and pricing, which helps to make a better decision. However, make sure to compare apples with apples when comparing quotes. It is important to consider that different PV companies structure their pricing in different ways, so be sure you understand exactly what each company is offering before comparing their pricing. 

When comparing proposals from various companies, consider the following: 

  • Equipment selection: the selection of tier 1, quality equipment will likely push the price up slightly, but it will mean that the system is better able to perform over its 25 year lifespan.
  • Inverter and panel derating characteristics: the derating of inverters and panels will affect the ability of the PV system to produce power over time
  • The sizing of the PV system: Is is optimally sized in order to meet your load requirements? A system that is too large or too small won’t save you the optimal amount of money. A slightly higher AC-DC ration will also affect price.
  • Lifetime savings and guaranteed savings: make sure you compare these two metrics, as the initial EPC price might differ but offer more in the way of lifetime savings, etc.  
  • Total guarantee/warranty package, insurance and liability: what parts of the system are insured and have warranties? This will affect the costs of upkeep and maintenance of the system. 

If you are thinking of entering into a solar Power Purchase Agreement (eg. buying solar energy directly), consider the following when comparing quotes:

  • The length of the PPA. Generally, the longer the PPA, the more affordable the tariffs will be. The length of the PPA will need to suit your business’s needs over the long term, considering things like whether the business would like to take ownership of the PV system.
  • The tariff escalation. At a first glance, a PPA tariff might appear higher, but it will have a lower escalation throughout the length of the PPA. Understanding the escalation is important to consider
  • Any upfront payments – again, a lower tariff might be because of a large upfront payment, so it is important to consider when comparing quotes. This is also the case with any bullet payments during the term or at the end of the PPA. 
  • Whether insurance and part replacement is included in the tariff. Again, a lower tariff might have excluded these items, making the costs more over the long run.
  • Forex – how forex is calculated and included on the agreement will affect the price. 

Don’t: Delay the solar procurement process

As much as it is important to practice due diligence when procuring solar PV, delaying the process unnecessarily is also seriously detrimental to the solar PV process. Solar PV savings start from day 1 – meaning that delaying the process is also delaying the cost savings. If the process is delayed, there could be unnecessary complications and expenses, such as 

  • Availability of the construction team and build schedule – most companies have tight timelines and their availability could mean that the process is further delayed if your project is not booked into the build schedule timeously.
  • SSEG applications – delaying choosing a solar PV provider can result in a delayed SSEG application, which can result in delays to switching the PV system on (and thus benefiting from the clean energy that it provides!)
  • Structural assessments – delaying the procurement process can also affect the structural assessment process, which is an essential part of rooftop solar PV systems. This can result in an overall delay of constructing the project. 

Dont: forget to calculate your cost savings through solar – both monetary and environmental 

At the end of the day, the solar PV system will save your business significantly in terms of operational costs. However, there is also significant benefit in terms of environmental savings. Keeping track of the carbon emissions savings is an important way to acknowledge the value of the solar PV system. 

Making sure that you have a competent Operations and Maintenance Service Partner will ensure that you can keep track of the relevant cost savings on a monthly basis and ensure that the plant is performing optimally. This can help to diagnose and solve any issues early, saving money for your operations.

If you have opted for a solar PPA, ensure that your partner provides you with carbon emissions savings with your monthly invoice, so that you can use the data when calculating your overall carbon savings. Solar PV is a choice that not only saves money – it is a conscious choice that ultimately will sustain generations to come. It’s something to be proud of, and use in your marketing strategy.

In conclusion, solar installations are useful for industrial facilities. Saving costs and carbon, they are a surefire way to increase cost savings. Following the above dos and don’ts will ensure that your solar installation is ultimately the right fit for your business. 

Solar for mines

How solar for mines helps to reduce operational costs and achieve a lower carbon footprint

Reliance on third-party infrastructure a significant risk for mines

The outlook for the mining industry in South Africa was a mixed bag in 2018 with bulk commodity prices continuing to rise from their lull at the beginning of 2016, while precious metals continued to struggle. Cost increases have put the mining industry under significant pressure and although price plays a crucial role in profitability, there are large fixed-cost elements associated with mining. Thus maintaining and ensuring optimum production levels plays a significant role in achieving profitability. 

This is why reliance on over-stretched third-party electricity suppliers such as Eskom can compromise profitability. In PwC’s annual publication highlighting trends in the South African mining industry it was reported that one of the significant subcategories driving risk is reliance on third party infrastructure with the cost and availability of electricity and water still a concern.

Mining facilities that typically rely on diesel electricity can use a solar microgrid to reduce the overall cost of energy, increase energy resiliency, thus ensuring control of their energy and power requirements. SOLA’s energy storage services department has considerable experience in combining battery storage solutions and existing generators in microgrid systems ensuring a continuous, uninterrupted electricity supply which is integrated with all other power sources.

Namibia and Botswana considering a 20-year, 4.5 GW solar push

‘The market for electricity produced by the mega-solar projects in Botswana and Namibia includes 12 other countries in the region that could be connected via new and/or upgraded transmission infrastructure,’ – WEF

The World Economic Forum’s (WEF) Global Future Council on Energy, has revealed that the governments of Botswana and Namibia are planning to develop 5 GW of solar capacity over the next two decades. Namibia and Botswana are considered perfect candidates for solar owing to their high solar radiation, strong legal and regulatory environments, suitable land availability and potential to host a low-cost, efficient electricity market to meet rising demand in the region. It has been suggested that this ambitious project, if completed, could lead to Namibia and Botswana exporting power to South Africa.

Botswana, a founding partner in a responsible mining initiative

Reducing carbon emissions is part of a global trend in the mining industry. Bloomberg reported last month that an explosive demand for renewable energy is expected to drive a global rush of exploitation, thus Botswana, the US, Australia and Peru are founding partners in an initiative to encourage responsible mining of rare earths and other minerals used in renewable energy projects such as solar panels, wind turbines and car batteries. 

Botswana’s mining industry contributes a third to the country’s GDP and 50% of tax earnings, and although the last quarter has seen a dip, economic growth is projected to pick up to 4.6% in 2020, supported by ongoing structural reforms aimed at diversifying the economy. It is perfectly primed to implement solar energy storage for mines owing to high solar radiation, the remote location of its mining facilities, weak grid supply and reliance on diesel.

Projected economic growth in Namibia in 2020

The IMF reports that Namibia’s economy will return to growth in 2020 after contracting for three straight years, though a failure to implement structural reforms could contribute to sluggish growth. Namibia has the second highest solar irradiation levels in the world, thus making solar energy storage for mines an appealing option.

No longer a question of if, but when

‘Industries that aren’t moving towards zero-carbon emissions will be punished by investors and go bankrupt’

Industries that aren’t moving towards zero-carbon emissions will be punished by investors and go bankrupt, warned the governor of the Bank of England, Mark Carney, last week. Thus renewable and storage technologies present the perfect solution by reducing energy costs while improving power quality and lowering carbon emissions.

The climate crisis will have a real financial effect on all major industries. Last Tuesday Carney told large corporations that they had two years to agree to rules for reporting climate risks before global regulators devised their own and made them compulsory.

Energy autonomy or supplementing grid supplied energy with embedded energy generation are both solutions to optimising production costs and reducing carbon footprint. Solar PV is both a cost-effective and decentralised form of energy, making it perfect for mines and other large scale energy-producers choosing to supplement their supply.

 Off-grid solar provides the ideal energy storage solution for mines. Remote locations, weak grid supply and reliance on diesel provide the optimal business case for solar PV microgrid. To test if your mining facility is suited to making the switch to off-grid make use of SOLA’s user-friendly mining tool.

Is solar energy suitable for my business?

You may have heard of solar PV – perhaps you even know other businesses that are using it. However, you might be wondering if solar PV is relevant for your business. It is worth considering that various factors affect the overall costs and tariffs of solar PV systems. 

Is solar PV right for my business?

At the outset, the best way to determine if your business could benefit from solar PV is by asking a few simple questions:

  1. Are you based in an area with good irradiation (solar resource)?
  2. Do you have a good quality, spacious roof or available open land near to your business?
  3. Do you use the bulk of your energy during the day?
  4. Are your reliant on diesel generators to keep your operation running during power cuts or because of lack of grid access?

If you answered “yes” to any two of the above, solar PV is definitely worth considering for your business. The aspects mentioned above are explored in more detail below. 

1. Good solar irradiation

It goes without saying, but solar PV performs better under conditions with great solar irradiation. If you are based in Africa, you are lucky: Africa has some of the best solar irradiation in the world, so it is generally a no-brainer. However, there are a few factors that might influence the quality of irradiance, which could affect the overall PV system size and thus the cost.

  • Weather: Weather can influence the quality of the irradiance. Things like extreme heat and humidity can affect how well solar modules perform, making irradiance quality vary in different geographic locations.
  • Pollution: pollution in the form of smoke and gases or particles can lower irradiation; it can also collect on solar modules and reduce their efficacy. 
  • Shading: Factors such as large buildings, highways and trees can shade roof areas during the day, causing the solar PV to stop producing. If your solar PV engineering firm is reputable they should be able to carry out an extensive shading analysis. 

2.Roof space and quality

Rooftop solar PV is often the most cost-effective solution for Commercial and Industrial businesses. As such, the size of your business’s roof, including the type of roof and if it is structurally sound, is an important factor to consider when scoping out the feasibility of solar PV.

If your roof is not suitable for mounting solar panels, it is important to consider if there is land nearby that could house a ground-mounted solar PV solution. All of these factors can affect the cost, and therefore the feasibility, of solar for your business. 

3.Energy Demand and use

An essential factor to evaluating the efficacy of a solar PV system is energy demand and use. Two factors come into this: the business’s peak power (kVA) requirements, as well as its electricity use (kWh). If the business is a high energy consumer, especially if it runs 7 days a week, the costs of solar will likely be much cheaper. However if the business has large amounts of electricity usage at night, for example, it might make the cost of the system more expensive. 

4.Diesel generator usage

In Africa, many business operations rely on diesel generators in order to keep the power on, either due to weak or unreliable electricity grids, or because they have no access to the grid. In general, electricity generated by diesel is very expensive, making a solar PV microgrid, including batteries, a great way to save and cut back on this. 

Procuring solar: your options

If you are convinced that solar PV sounds like a good intervention, remember that the following options exist to procure solar PV for your business:

  • Buy solar energy directly – enter into a solar PPA in order to use solar PV electricity without any capital expenditure. The solar PV system belongs to SOLA, and you simply pay for the electricity that you use. The longer the term of the PPA, the lower the tariff over the system’s lifespan (20 years).
  • Build a solar PV system – purchase a solar PV system that your business will own, and simply pay for annual maintenance and upkeep. SOLA will design and construct the PV system for you, ensuring that it performs as predicted, and will maintain the system going forward.

Industrial and Commercial solar PV projects

SOLA secures R400M to finance solar PV projects for Commercial and Industrial properties through Power Purchase Agreements

A clean fund for the future

The SOLA Group has secured R400m in order to build commercial and industrial solar PV facilities across Southern Africa. The renewable energy fund, Orionis, will enable 40 MW of solar PV projects to be built without capital expenditure by the electricity off-takers.

The deal is a result of a partnership between the SOLA Group, African Infrastructure Investment Managers (AIIM), and Nedbank Energy Finance, who have partnered to provide affordable solar PV solutions for businesses that are in dire need of electricity security.

Chris Haw, chairperson of the SOLA Group, believes that  the clean energy solutions created by the fund are timeous.
“This partnership brings together three highly experienced entities whose combined skills offer consumers clean energy solutions at a time when our country desperately needs it,” he said. 

“This partnership brings together three highly experienced entities whose combined skills offer consumers clean energy solutions at a time when our country desperately needs it”

SOLA’s extensive track record of developing and building solar PV has allowed for the development of the Orionis fund, which will have the ability to fund 40 MW worth of projects. The forthcoming pipeline already includes 15 MW of solar PV Power Purchase Agreements, including several breweries and other industrial facilities around South Africa. The consumers pay for their clean energy directly, through a PPA tariff that is typically 20% lower than Eskom or their municipal provider’s rates.

The financed model would allow sectors focused on short-term cost reductions in their Opex budgets, such as FMCG companies, the opportunity to tap into solar power. This would allow reductions in operating costs and in carbon emissions, which are generally very important to industrial sectors. The financed solar PV is provided through a legal arrangement called a Power Purchase Agreement.

What is a PPA? 

A commercial solar PPA enables a fully integrated solar photovoltaic system to be installed and provide electricity to the entity through a customised monthly payment plan, typically at a tariff that is 20% lower than Eskom. PPAs can also include the option to take ownership of the PV system at the end of the financed period, with no upfront installation costs. The conditions of power purchase are detailed in the PPA which is negotiated directly with each client to ensure the agreement is workable for both parties.  

How do clean energy funds reduce opex?

As mentioned, financed renewable energy projects will enable industrial facilities to access secure and cheaper power, and free up capex for investment into their core business activities. But how does this work? 

Over the last few years, reduced costs of embedded electricity generation such as solar PV have interrupted the traditional model of electricity production. In other words, solar PV power is rapidly becoming the cheapest form of power to procure globally. In order to fund solar PV projects, however, large sums of capital are needed in order to permit, design, construct and keep the solar PV operational – similar to a regular utility such as Eskom. 

Whilst companies can opt to buy their PV systems outright, through an Engineering, Procurement and Construction (EPC) option, there is often little need for the entity to own the PV system themselves, as their main goal could be to reduce their operating expenses. Without available Capex, companies would need to secure financing in order to fund the construction of these projects.

SOLA’s PPA offering, through consolidating the finance, design, construction and operation of solar projects, allows companies to access cheaper finance than procuring it individually. “Operating at scale allows SOLA to provide lower tariffs and more competitive rates, reducing costs of financing,” adds Haw. 

For large commercial and industrial companies, PPAs enable flexible procurement of electricity, allowing them to consume the cheapest electricity available at a given time whilst also reducing their carbon footprints.

How financed solar PV can support the African Economy

Allowing small-scale, and flexible embedded generation of electricity is a key aspect to transition to a low-carbon economy, as it allows for increased penetration of renewables. 

Supporting the further deployment of small-scale embedded generation (SSEG) plants, according to Council for Scientific and Industrial Research (CSIR) Energy Centre, will also create thousands of full-time jobs and help to grow hundreds of small businesses across the country. The SOLA Group currently employs 50 full-time staff members for its South African operations, and the construction of 40 MW of solar PV projects through the fund is likely to create an additional 880 jobs in the coming years.

“The model of electricity generation that incorporates both centralised and distributed electricity will improve the ability for South Africa to meet energy demand, reduce electricity costs and strengthen resilience to outages,” concludes Haw. 


FMCG industrial manufacturing has great potential for Africa

Solar for the FMCG Sector: Clean Energy Solutions that Work

FMCG players

FMCG is one of the largest drivers of the industrial sector in Africa, presenting a wealth of opportunity for manufacturers and distributors. The industry is comprised of non-durable goods that are produced, sold and consumed quickly. These products take the form of consumables such as beverages, packaged foods, toiletries and over-the-counter medication.

Fast-moving consumer goods (FMCG) are a market with tremendous potential to drive economic growth in the SADC region and further afield. However, the industry is heavily dependent on reliable power, secure and efficient transport routes and strong distribution networks. FMCG typically have a small profit margin but are lucrative when sold in large quantities, thus a reduction in energy costs goes a long way towards bolstering narrow profit margins.

FMCG industrial manufacturing has great potential for Africa

Brilliant technologies and brave entrepreneurs

‘Africa has nine times the solar potential of Europe and an annual equivalent to one hundred million tons of oil.’

In a recent article in the Journal of International Affairs Professor Wim Naudé reports that in a landscape of brilliant technologies and brave entrepreneurs the future is looking bright for African manufacturing. According to Naudé, renewable energy technologies like solar panels and batteries may be expected to improve the competitiveness of African manufacturing.

Peter Diamandis, founder and CEO of the X Prize Foundation, and journalist Steven Kotler note that ‘Africa has nine times the solar potential of Europe and an annual equivalent to one hundred million tons of oil.’

The resources are there and the benefits in terms of cost are undeniable. Notable FMCG industry leader Coca-Cola Beverages Africa (CCBA) recently installed a 574 kWp solar facility at the Coca-Cola Namibia Bottling Company (CCNBC). The project is expected to produce 1,016,760 kWh of energy in the first year of production, with appreciable Energy and Demand charge savings expected in the first year of production. In addition this project results in 901 tons of CO2 reduction per year of operation. Given that Namibia’s solar irradiation levels are the second highest levels in the World (at 3000 kWh/m² over a large part of the country) and NamPower tariff increases are inevitable, it makes considerable sense to look to industrial solar power for cost-savings and decentralised efficiency.

The environmental benefits for your brand

The Learning and Development Director at IRI, Marylee Townshend predicts that given considerable global and local societal shifts in the past year, FMCG brands which stand for something are likely to win out in a competitive environment. Staying neutral is no longer an option as more consumers than ever before are developing a preference for ethical and environmentally-friendly products. This is a double win for manufacturers and distributors who commit to clean energy solutions, in terms of having a stable, cost-cutting energy source and brand success. Notable industry leader Fair Cape Dairies has stepped up to the plate by procuring solar PV  energy to provide clean, noise-free electricity to the farm during the day, while reducing the farm’s total energy consumption by 16% per annum over its 25-year lifespan.

‘Businesses that commit to clean energy, such as Fair Cape Dairies, are helping to lead the way for South Africa’s sustainable development,’ explains Dr Chris Haw, chairperson of SOLA and head of the Solar Finance division.

Plattekloof Village Shopping centre, owned by industry heavy-weight Pick n Pay Retailers, has also embraced clean energy solutions with a 944 kWp solar system on its roof, which is expected to generate 1.4 million kWh of clean electricity per year. Plattekloof Village is part of a growing fleet of shopping centres electing to supplement their electricity supply with decentralized solar PV. Given the recent challenges to Eskom’s ability to supply uninterrupted electricity it is unsurprising that malls, factories and distribution centres are increasingly looking to independent energy solutions. The ample roof space available and considerable daily energy use typified by these organisations makes industrial solar power the ideal solution.

FMCG challenges

FMCG is a challenging arena with many considerations for facilities managers. These include product placement and competition. Townshend contends that big data is increasingly the driving force behind tactical decisions in FMCG. In addition loyalty card data provides unparalleled insight into consumer behaviour. Given the financial climate in the region, cutting costs and value-for-money is an immediate concern for consumers. Narrow profit-margins in the FMCG industry means that every expense matters; this is when cost-efficient energy management becomes imperative.

Breweries and other FMCG industries can benefit from solar PV

Simplifying Electricity Management

Conservative consumption and optimum production are key to the success of every industrial FMCG facility. A good place to start is a comprehensive look at electricity bills over the course of a year. Following this analysis, spikes in energy consumption will quickly emerge, and from there it will be easier to implement energy-saving regimens. Introducing solar has been proven to result in considerable energy and cost-saving benefits. Once one has identified the peak capacity charges, measures can be made to reduce overall energy costs even if total energy consumption remains constant.

Solar financing

‘Solar finance – through a power purchase agreement – allows these businesses to commit to their targets and reduce their carbon emissions through buying clean energy directly…’

There are two options when considering harnessing the cost-saving benefits of industrial solar.

Firstly there is the outright buy or EPC solution, such as the facility at CCBA Windhoek, which purchased the solar system upfront to save on energy costs. Industrial energy consumers can save significantly by altering their electricity load to peak during the day when the solar PV system is most productive, thus reducing demand charges significantly. In a facility such as the CCBA Windhoek, the cost of the solar PV system is insignificant compared to the amount that it will produce over its lifetime.

The second option is a solar PPA, or power purchase agreement. This arrangement allows businesses to purchase solar PV-generated electricity with no upfront costs, while enjoying the immediate cost-saving benefits, such as the demand charges described earlier. The benefits of solar PPAs for industrial facilities are fixed tariff increases and monthly payment amounts, rather than lump-sum capex investments. Similarly, the solar PV system is not registered as an asset on the facility’s books, but is rather owned and maintained by a solar finance provider such as SOLA. After a few years, the facility can opt to buy back the solar PV system, or take ownership of the system after a specified number of years.

Such an arrangement was entered into by SOLA and Fair Cape Dairies. As Dr Haw explains, ‘Companies such as Fair Cape Dairies that have committed to sustainability goals, may not want to purchase a solar system outright. Solar finance – through a power purchase agreement – allows these businesses to commit to their targets and reduce their carbon emissions through buying clean energy directly. During the day, Fair Cape Dairies will use the clean energy generated on their roof for their own consumption needs, without owning the solar system themselves.’

Dairies can benefit from financed solar PV solutions

As the costs of solar equipment continue to fall, industrial solar power systems in Southern Africa are more viable than ever. Given Eskom’s escalating tariffs, large-scale solar facilities are able to provide consistent power for industrial operations at costs lower than Eskom’s lowest bulk tariff. Solar PV is both a cost-effective and decentralised form of energy, making it perfect for large-scale energy users in the FMCG sector.


Is solar the green solution agribusiness needs?

Agribusiness contributes significantly to a country’s overall industry outlook, particularly because of its links to sectors such as chemical processing and manufacturing. Locally, SADC has identified agro processing as one of three regional priority value chains, along with mineral beneficiation and pharmaceuticals.

That being said, the economic challenge that farmers and agribusiness are facing is a tough one. Over the ten years up to 2017, electricity tariffs to state utility Eskom have risen by 356 percent – four times the rate of inflation over this period. The power utility has requested an additional 15% increase for the 2019/20 period, although the National Energy Regulator of South Africa (Nersa) seldom grants the full requested increase. The coal shortages this November that led to the shut-down of 11 power stations also highlight the uncertainty of the operating climate for South African industry.

In addition to soaring prices of electricity and uncertainty of supply, business in South Africa is affected by climate change. Agriculture is particularly affected by the cycles of rain and drought, as well as temperature, which are both affected by climate change. And because agriculture is, ironically, one of the leading causes of climate change, consumers are now demanding that farming practices meet stringent environmental and ethical standards.

Trade and Industry Minister in South Africa, Rob Davies, acknowledged that uncertainty in this arena is hampering economic growth, following his announcement in October that agro-processing is one of the sectors that government will be targeting with incentives to revive South Africa’s struggling economy.

Solar could give a growth spurt

Given this difficult context, it’s no wonder that Agro-processing is in need of bolstering in South Africa. Embedded generation, which is the small-scale production of power within the electricity distribution network, situated close to the place of consumption, is a great solution to counteract the explosive costs, and unreliability, of grid-tied energy. The cost, per kWh, of solar PV (the most common form of embedded generation)  has dropped dramatically in the past years due to increased uptake globally that has pushed down manufacturing prices. Adopting this cheaper source, close to the point of consumption, can lower the running costs of agro-processing plants significantly, giving them a leg-up in tough economic times.

Financed solar through PPAs

However, in order to purchase a solar PV system, businesses need to outlay capital, which might not be the most appealing option for agribusiness, whose capital budget is used for much-needed maintenance and plant upgrades. However, power purchase agreements (PPAs), which are a way of financing renewable energy systems such as solar, are an attractive alternative.

Renewable solutions are now at the point where they can provide a viable and cost-effective alternative for businesses in this sector.

Entering into a PPA in South Africa is a way for agribusiness to shield themselves from Eskom tariff increases, as it is possible to purchase renewable energy at a lower rate than what Eskom can provide, with a fixed tariff increase.

This is particularly pertinent due to Eskom’s recent 15% tariff increase application. Should a large portion of their energy come from solar, agribusinesses can use solar PPAs to shield themselves from the volatility of Eskom.

Renewable energy is also a significant mitigator of environmental harm, because it reduces industry’s reliance on coal-burning power generation, which releases greenhouse gases into the environment. Reducing greenhouse gas emissions is important for agribusiness, who often have sustainability targets.In fact, every industry should be concerned with addressing the realities of climate change – but none more so than agriculture, which is dependent on steady and predictable weather patterns.


Challenges and possibilities for agribusiness in South Africa

Solar PV power plants are also decentralised and can easily provide power in rural areas without having to erect new infrastructure, such as power lines. However, in South Africa, applying for a grid-tied solar PV system on Eskom infrastructure remains a challenge. Eskom’s independent power producer [IPP] connections do make provision certain for low- or medium-voltage connections, but they require a letter of exemption from Nersa, which is almost impossible to obtain without certainty around the IRP – which should be finalised in February, according to the Minister of Energy Jeff Radebe.

The energy landscape has changed significantly since that Eskom’s memo on low and medium voltage connections was released, and solar PV connections are now much more viable for companies and farms that are currently connected to Eskom infrastructure. Many more businesses would now like to opt for embedded power generation. The updated IRP restriction of only 200MW of embedded generation – which is where the low- and medium-voltage connections will be found – limits the generation capacity that the agro-processing industry urgently needs.

If more and more businesses lobby Eskom to allow low- and medium-voltage connections, they will be able to benefit from competitive electricity prices, while also reducing their carbon footprints. This will serve their stakeholders – and the environment they rely on – well into the future.

Solar PPAs are an affordable way to access the benefits of solar electricity

5 FAQs about solar PPAs

In some of our previous posts, we’ve alluded to the benefits of a solar PPA: both as a way to provide more options for business owners wanting to go solar, and as a way of reducing costs in certain sectors. At this point, you may be convinced that solar finance is an affordable way to access green energy for your company, but you may have a few questions. In this blog, we explore the 5 most common questions about the most common form of solar finance, the solar power purchase agreement or PPA.

Why a PPA?

As we mentioned in the previous blog, a solar PPA usually enables an electricity consumer to utilise solar energy at a rate that is cheaper than the existing utility. In addition the ownership of the solar system remains with the PPA provider, and the user only pays for the electricity that they consume, rather than for the overall cost of the solar system – making it an affordable choice for several sectors. Below follow some of the most frequently asked questions about solar PPAs.

1) How long does a solar PPA last?

In fact, this question gets asked so often that we wrote an article about how long solar PPAs are already, and if you’d like a detailed answer to the question, have a look at that article. The summarised answer is, “it depends”. Whilst as a rule of thumb, the longer the PPA, the greater the  immediate cost-savings will apply, many businesses prefer to enter into a shorter PPA period for a higher tariff, after which time the system ownership is transferred to the energy user. It all depends on the requirements of the client, as well as the overall objectives of the project.

2) Do I have to own the building to enter into a solar PPA?

PPAs ideally take place between a building owner and an energy provider, since the construction and ongoing maintenance, as well as energy distribution throughout the building, will require the building owner’s input and buy-in. However, if the building owner agrees to make the rooftop available for the solar system and the agreement takes the building and end user into account, tenants may be able to enter into a PPA.

3) If it isn’t sunny, do I still pay?

Depending on the type of PPA agreement you enter into, you shouldn’t have to pay if the system is not generating energy (take into consideration though, that even on cloudy days solar systems generate a good amount of power). However, the opposite does apply: if it is very sunny and producing more than what the building is consuming, the client may be liable for a minimum payment for the energy that is wasted, should it not be used. That is why it is essential to ensure that the system is sized correctly.

4)What happens at the end of the PPA?

Depending on the type of agreement, the system may transfer over to the client who then will take ownership of the solar system. This could work well if the building owner wishes to take  ownership of the system after a period of time. However, there can also be “early exit” options, if the property owner is concerned that the building might be sold during the PPA term. Again, each situation is different, and when entering into a PPA it is best to check if the agreement contains provision to either buy the system, or to get the new building owner to assume the PPA, should the building be sold.

5)What is included in the PPA tariff?

Depending on the type of agreement you enter into, the tariff will include the costs of designing the system, procuring all necessary components, and constructing the system on the suitable rooftop or ground-mounted area so that the solar electricity is readily available for the client. The tariff also includes the costs of maintaining the system on an ongoing basis, such as cleaning and part replacement as needed. Typically, these combined costs will be similar, or less than utility based power when comparing on a per-kWh basis.
