The Industrial Electricity Problem

Most Sub Saharan African countries are at an industrialization crossroads, where the push into Middle Income status is being held back by the lack of adequate power supply. South Africa is a standout case, where it has adequate infrastructure in place for industry but suffers due to grid operator mismanagement. In all cases, regular load shedding and blackouts.
The rise of inexpensive distributed solar and battery to store it has shown a path around state utility monopoly over transmission and distribution. And over the next decade, grid decentralization will trigger economic growth.
Countries across Sub Saharan Africa face several core electricity challenges that impact industrial companies. While these challenges may vary between different companies and sectors, the most common issues include:
Grid decentralization refers to the shift from a few large, centralized power plants distributing electricity over long distances to numerous smaller, localized power sources. This can include a variety of renewable sources such as solar panels, wind turbines, and batteries. Crucially, these decentralized power sources can often be managed collectively as a Virtual Power Plant (VPP), offering the resilience and responsiveness of a traditional power plant but with much greater flexibility.
So why is grid decentralization necessary, not just in South Africa, but across Sub-Saharan Africa?

Addressing Power Inequality

According to the World Bank, more than half of the population in Sub-Saharan Africa lack access to electricity, a statistic that dramatically underscores the current power inequality. Grid decentralization has the potential to bridge this gap. Decentralized energy sources, such as solar panels and small-scale wind turbines, can be installed in remote or underserved areas, providing a reliable source of power and improving the quality of life for many.

Mitigating Load Shedding

Load shedding – the deliberate shutdown of electric power in parts of a power-distribution system to prevent the failure of the entire system – is a frequent occurrence in many parts of Sub-Saharan Africa, including South Africa. By spreading the energy generation capacity across numerous smaller sources, grid decentralization reduces the strain on central power plants, making load shedding less likely. This in turn ensures a more reliable power supply for homes, businesses, and industries.

Stimulating Economic Growth

Grid decentralization can drive economic growth. The installation, maintenance, and management of decentralized energy sources can create jobs, stimulate local economies, and encourage technological innovation. Additionally, reliable access to power can enable the growth of businesses and industries, contributing to broader economic development.

Enhancing Energy Efficiency

Decentralized power generation often occurs closer to where the energy is consumed, reducing transmission losses and increasing overall energy efficiency. Furthermore, modern VPP technology allows for intelligent management of power sources, optimizing power generation and consumption based on real-time demand.

Financing the Decentralized Grid

As South Africa and the rest of Sub Saharan Africa grapple with the realities of load shedding, the appeal of decentralized energy solutions like microgrids is growing. However, the initial setup cost can be daunting for businesses. Fortunately, there are several financing options available to help businesses implement microgrid systems and ultimately achieve energy autonomy.

Direct Purchase

The most straightforward method of financing a microgrid is through direct purchase. This requires a significant upfront investment but allows for total control over the system. Businesses that have adequate capital and are confident in the long-term benefits of a microgrid may opt for this route. Over time, the costs of the system can be recouped through energy savings and potentially selling excess power back to the grid.

Loans

Traditional loans from banks or other financial institutions are a common method of financing microgrid projects. The advantage of a loan is that it allows businesses to spread the cost of the system over a longer period. However, loans typically require collateral and have strict repayment terms, and interest rates can add a substantial amount to the total cost of the project.

Leasing

Leasing is another option for businesses looking to implement a microgrid without the large upfront cost. Under a lease agreement, the business pays a monthly fee to use the microgrid system but does not own it outright. Leasing can be an attractive option for businesses that want to reduce their energy costs without the responsibility of owning and maintaining the system.

Power Purchase Agreements (PPAs)

Power Purchase Agreements are a popular financing option for microgrids. In a PPA, a third-party developer owns, operates, and maintains the microgrid. The business agrees to purchase the power generated by the microgrid at a predetermined rate for a specified period. This allows businesses to benefit from the microgrid without the need for a significant upfront investment or ongoing maintenance responsibilities.

Green Bonds

Green Bonds are a relatively new form of financing that is specifically designed for projects that have environmental benefits, such as microgrids. These bonds are issued by a company to raise capital for green projects and are backed by the issuer's balance sheet. They are an attractive option for socially conscious investors and can provide substantial funding for microgrid projects.
While the upfront cost of a microgrid can be significant, there are numerous financing options available to businesses in South Africa. Microgrids also create a much-needed set of alternatives to buying power and transmission from state-owned utilities change in the electricity market. Now, there is competition and existential pressure on utilities or Independent Power Producers to deliver a basic level of service.
