Empowering Green Growth: A Guide to Financing Renewable Energy in South Africa

Introduction

South Africa’s energy landscape is characterized by a heavy reliance on coal, which has traditionally been the primary source of electricity, supplying about 77% of the country’s needs. 

This dependence on coal has placed South Africa among the highest emitters of greenhouse gasses per capita in the world. However, the country is experiencing significant shifts towards renewable energy due to several key factors.

The frequent load-shedding events caused by the unreliability of aging coal-fired power plants have prompted the exploration of more stable and sustainable energy sources. Renewables, such as wind and solar, have become increasingly cost-competitive, offering more predictability in energy costs.

Section 1: The State of Renewable Energy in South Africa

Solar power, both in the form of large-scale photovoltaic (PV) plants and smaller, embedded systems, is growing. The capacity of privately owned, embedded solar PV almost doubled that of utility-scale PV by December 2023. This surge is driven by factors like increasing electricity prices and more frequent load-shedding​

Hydropower and other renewable sources like bioenergy also play roles, though their specific contributions are smaller compared to wind and solar.

Section 2: Financing Renewable Energy – Traditional Options 

  1. The Sun Exchange – This company utilizes a crowdfunding model that allows individuals to finance solar cells in larger solar projects. Investors can fund individual solar cells and earn returns based on the power generated by their leased solar cells. This model is particularly innovative as it lowers the barrier to entry into the renewable energy market for average investors.
  2. African Development Bank (AfDB) – The AfDB provides financing aimed at supporting green growth initiatives across Africa, including renewable energy projects through facilities like the Green Bond program. This is more oriented towards larger projects and governmental or large corporate financing rather than individual consumers.
  3. Standard Bank and Absa Bank – These banks have been active in financing green energy transitions. They offer various financing options that might be suitable for businesses looking to invest in renewable energy solutions, including backup power systems. They are part of a broader move by South African banks to support the country’s transition to renewable energy.

Benefits of Traditional  Financing Options 

  1. Lower Cost of Capital: Traditional financing options like bank loans often come with lower interest rates compared to venture capital funding. This can result in lower overall financing costs for businesses, making renewable energy projects more financially feasible in the long run.
  2. Stability and Security: Banks typically offer more stable and predictable financing arrangements compared to venture capital firms. Businesses can benefit from fixed interest rates, longer loan terms, and predictable repayment schedules, providing greater financial stability and security over the life of the renewable energy project.
  3. Ownership and Control: Unlike venture capital funding, which may involve giving up equity or control over the business, traditional financing options like bank loans generally do not require businesses to relinquish ownership or decision-making authority. This allows businesses to retain full control over their operations and strategic direction.

Cons of Traditional  Financing Options 

  1. Stringent Requirements:  Banks often have strict lending criteria and may require businesses to demonstrate a strong credit history, stable cash flow, and collateral to secure financing. This can be challenging for newer or smaller businesses, particularly those operating in the renewable energy sector, where revenue streams may be less predictable or established.
  2. Limited Expertise:  While banks provide financing, they may lack the specialized knowledge and expertise in renewable energy technologies and markets that venture capital firms offer. This could result in limited support and guidance for businesses navigating the complexities of implementing renewable energy systems effectively.
  3. Risk Aversion: Banks tend to be more risk-averse than venture capital firms, particularly when it comes to financing innovative or emerging technologies like renewable energy. As a result, they may be hesitant to provide funding for renewable energy projects that they perceive as high-risk, potentially limiting access to capital for businesses in this sector.

Understanding these benefits and drawbacks can help businesses evaluate whether traditional financing options like bank loans align with their financial needs and objectives for implementing renewable energy systems.

Section 3: Innovative Financing Models

Green Bonds

Green bonds are a type of fixed-income instrument specifically earmarked to raise money for climate and environmental projects. These bonds are typically asset-linked and backed by the issuer’s balance sheet, and they are designated to fund projects that have positive environmental and/or climate benefits.  

Examples:

  1. In 2019, the City of Cape Town issued its first green bond, raising R 1 billion to fund electric buses and energy efficiency in buildings among other projects. This bond was oversubscribed, highlighting strong investor interest in sustainable projects.
  2. Nedbank issued a green bond through the Johannesburg Stock Exchange to raise funds specifically for renewable energy projects, energy efficiency, and biodiversity conservation.

Power Purchase Agreements (PPAs)/Rent To Own 

Overview: Power Purchase Agreements (PPAs) are contracts between two parties: one that generates electricity (the seller) and one that purchases electricity (the buyer). In these agreements, the system is installed on the buyer’s property but remains owned by the private company (the seller). The buyer then pays for the power generated. Alternatively, a second option allows the buyer to enter a rent-to-own arrangement, where they pay monthly installments over a specified period to eventually own the setup.

Role in Renewable Energy: PPAs facilitate the funding of renewable projects by ensuring a stable and predictable revenue stream for project developers, making it easier to secure financing from banks or other financial institutions. This is particularly important in renewable energy, where upfront costs are high but operational costs are relatively low.

Comparative Analysis on Cost

Cost FactorTraditional OptionPPA Option
Initial InvestmentHighLow to None
Energy CostVariable, increasing over timeFixed, potentially lower
Maintenance CostsHigh, ongoingIncluded in PPA or minimal for rent-to-own
Total Cost Over 20 YearsHigher due to variable rates and high maintenanceLower due to fixed rates and lower maintenance

Benefits of the Rent-to-Own Model in PPAs:

  1. Affordability: Just as rent-to-own makes home ownership more accessible, PPAs make it easier for companies to access renewable energy without the need for significant upfront investment.
  2. Incremental Ownership: Over time, the buyer benefits from the consistent energy supply, similar to how a tenant gradually builds equity in a rent-to-own home.
  3. Sustainability: By facilitating the adoption of renewable energy, PPAs contribute to environmental sustainability, aligning with global goals to reduce carbon emissions.

Cons of Power Purchase Agreements (PPAs)

  1. Early Termination Fees: Exiting a PPA before the end of the contract term can incur significant penalties or fees, limiting flexibility for the buyer.
  2. Potential Cost Increases: While PPAs offer predictable rates, these rates may still be higher than future utility rates, especially if the cost of traditional energy decreases due to technological advancements or changes in market conditions.
  3. Long-Term Commitment: PPAs typically involve long-term contracts, often ranging from 10 to 25 years. This long-term commitment can be a drawback if the buyer’s energy needs or financial situation changes over time.

Venture Capital and Private Equity

Venture capital and private equity firms in South Africa have increasingly targeted renewable energy for investment, recognizing its potential for growth in light of the country’s energy needs and environmental commitments. These firms are also actively funding Power Purchase Agreements (PPAs), which provide a stable revenue stream for renewable energy projects, further enhancing their attractiveness as investment opportunities.

  2. Hlayisani Capital – A growth fund that has made investments in renewable and sustainable businesses, looking to capitalize on innovations that address energy challenges in Africa.

Benefits of Venture Capital and Private Equity

  1. Access to Capital: Venture capital provides businesses with access to significant amounts of capital that they may not be able to obtain through traditional financing methods. This capital can be crucial for businesses looking to invest in expensive renewable energy systems.
  2. Expertise and Network: Venture capital firms often bring more than just money to the table. They typically have a network of contacts, industry expertise, and resources that can help businesses navigate the complexities of implementing renewable energy systems effectively.
  3. Risk Sharing: Venture capital investors typically understand the risks associated with investing in emerging technologies like renewable energy. By providing funding, they help shoulder some of the risk that businesses face when adopting new energy technologies, which can be particularly important in an industry with regulatory uncertainties and technological advancements.

Cons of Venture Capital and Private Equity

  1. Loss of Control: Venture capital funding often comes with strings attached, such as giving up a certain degree of control over the direction of the business. Investors may require a say in decision-making processes, which could potentially conflict with the business’s long-term goals or values.
  2. High Expectations for Returns: Venture capitalists typically expect high returns on their investments to justify the risks they take. This pressure for rapid growth and profitability may not align with the longer timeframes often required for renewable energy projects to become financially viable, leading to potential conflicts between short-term financial goals and long-term sustainability objectives.
  3. Exit Pressure: Venture capital firms usually expect an exit strategy within a few years, typically through either an IPO or acquisition. This pressure to exit can create challenges for businesses in the renewable energy sector, where returns may take longer to materialize due to regulatory hurdles, technological uncertainties, or market dynamics. It may force the company to prioritize short-term gains over long-term sustainability and innovation.

Understanding these benefits and drawbacks can help businesses make informed decisions about whether venture capital is the right funding avenue for their renewable energy initiatives.

Examples of Tax Benefits in South Africa

 Accelerated Depreciation (Section 12B of the Income Tax Act):

Businesses investing in renewable energy assets can benefit from an accelerated capital depreciation allowance. This includes a 100% deduction in the first year for solar photovoltaic (PV) projects below 1 MW, and a structured deduction over three years (50% in the first year, 30% in the second year, and 20% in the third year) for projects above 1 MW. Recent updates have also introduced a 125% deduction in the first year for all renewable energy projects, regardless of their generation capacity, which is applicable for assets brought into use for the first time between March 2023 and February 2025​ (SA News)​​ (Cliffe Dekker Hofmeyr)​​ (UNCTAD Investment Policy Hub)​​ (RSM Global)​.

Section 12L: Energy Efficiency Savings Tax Incentive:

This incentive provides a tax deduction for businesses that implement energy efficiency measures. Companies can claim a deduction of 95 cents per kilowatt-hour (or equivalent) of energy saved as certified by the South African National Energy Development Institute (SANEDI). This encourages businesses to invest in energy-efficient technologies and practices, leading to reduced energy consumption and costs.

Research and Development (R&D) Tax Incentive:

Under Section 11D, companies engaged in scientific or technological R&D can claim a 150% deduction on qualifying R&D expenditure. This incentive aims to boost innovation and development in various sectors, including technology, manufacturing, and renewable energy. By reducing the effective cost of R&D activities, this benefit encourages companies to invest more in developing new products and processes.

Section 2: Current Tax Benefits for Renewable Energy Projects

Accelerated Depreciation (Section 12B of the Income Tax Act)

Overview: Section 12B of South Africa’s Income Tax Act provides an accelerated depreciation allowance for investments in specific renewable energy assets. This tax incentive is designed to encourage businesses to invest in renewable energy by allowing them to recover the costs of their investments more quickly through tax deductions.

Details of the Incentive:

  • Eligible Assets: The allowance applies to machinery, plant, implement, utensil, or article used in the production of renewable energy. Eligible sources include wind power, solar energy, hydropower (below 30 megawatts), biomass, and photovoltaic projects (above 1 megawatt).
  • Deduction Rates: Typically, businesses can deduct the cost of these assets at an accelerated rate:
    • 100% in the first year for small-scale projects, specifically solar PV projects below 1 megawatt.
    • 50% in the first year, 30% in the second year, and 20% in the third year for larger projects above 1 megawatt.

Impact and Importance: These tax incentives significantly reduce the financial burden on businesses transitioning to renewable energy sources. By accelerating the rate at which investments can be recouped through tax relief, the government not only makes renewable energy projects more economically viable but also aligns with global and national sustainability targets.

The combination of Section 12B benefits and additional deductions for renewable energy production underlines South Africa’s commitment to fostering a sustainable and independent energy sector. This approach not only helps mitigate the ongoing energy challenges but also positions the country as a leader in the adoption of renewable technologies in the region.

How these incentives reduce the overall project cost and encourage investment

1. Reducing Upfront Costs Through Accelerated Depreciation

Accelerated depreciation allows businesses to deduct the cost of renewable energy assets from their taxable income at a much faster rate than standard depreciation rules would allow. For example, under Section 12B, certain qualifying renewable energy assets can be fully written off in the first year of their operation. This immediate deduction significantly reduces the net cost of the asset in its initial year, improving the project’s cash flow early on. This is particularly advantageous because renewable energy projects typically require high initial capital outlays. By accelerating the rate of depreciation, the tax burden in the early years of a project is lowered, making these investments more financially viable and attractive.

2. Encouraging Larger and More Frequent Investments

The option to deduct 125% of the cost in the first year for all renewable energy projects, as recently introduced, further enhances this benefit. This means that investors can deduct an amount greater than the actual investment, leading to substantial tax savings. This additional deduction not only makes it more financially attractive to invest in renewable energy but also encourages larger and more frequent investments in the sector.

3. Improving Return on Investment

By reducing the tax liability, these incentives directly affect the return on investment (ROI) calculations for renewable energy projects. Lower initial costs and ongoing tax savings improve the financial returns and shorten the payback period of these projects. This makes renewable energy investments more competitive relative to traditional energy sources, which often have lower upfront costs but higher operational and environmental costs over time.

4. Stimulating Broader Economic Benefits

The financial benefits provided by these tax incentives can help stimulate further economic activity. Lower project costs lead to more disposable income for businesses, which can be reinvested into additional renewable energy projects or other areas of the business. Additionally, as more businesses invest in renewable technologies, there is a broader push towards innovation in the sector, driving down costs and improving efficiency through competition and scale.

5. Aligning with National Energy and Environmental Goals

These tax incentives align financial and business interests with national energy policies and environmental goals. By making it more economically attractive to invest in renewable energy, these policies encourage a shift away from fossil fuels, support energy security, and promote environmental sustainability. This alignment helps ensure that both economic and environmental objectives are met, contributing to a more sustainable future.
