Sector Classification

Situate the investment opportunity within sustainability focused sector, subsector and industry classifications.
Sector

Renewable Resources and Alternative Energy

Development need
Eswatini imports 80% of its energy from South Africa and Mozambique (22). The high dependency on energy imports contributes to the government’s fiscal deficit and increases Eswatini’s exposure to energy supply risks, namely supply security and price shocks, highlighting the need for increased domestic energy production capacity (1).

Policy priority
The Kingdom of Eswatini Energy Masterplan 2034 aims to reduce dependency on energy imports by advancing domestic energy production through the utilization of available renewable energy resources, such as biomass and solar, and to ensure sustainability, efficiency, accessibility and affordability of all energy sources (1).

Gender inequalities and marginalization issues
Although national electricity coverage in Eswatini is 87%, several rural inhabitants, especially smallholder farmers and small business owners, do not have access to electricity or cannot afford high tariffs (2, 3, 4).

Investment opportunities introduction
Eswatini is well endowed with renewable energy resources, which incentivizes investments in renewable resources and alternative energy, including scaling-up renewable energy power plants, especially solar PV and biomass, that will provide low-cost energy (1, 4).

Key bottlenecks introduction
Limited private participation in energy generation, lack of regulatory and fiscal incentives for investors, high infrastructure costs and lack of adequate institutional and private sector capacity to plan, prepare and implement viable renewable energy projects prevent uptake of renewable energy (2, 6).

Sub Sector

Alternative Energy

Development need
Eswatini's domestic energy supply is mostly derived from hydropower and sugar cane-based cogeneration, making the supply vulnerable to external factors such as droughts. Energy demand is expecting an 18.76% increase by 2034, placing further pressure to pursue alternative energy sources such as renewables (1).

Policy priority
Eswatini's National Energy Policy (5) and Nationally Determined Contributions (NDC) (9) commit to increase the share of renewables to 50% of the national energy mix and to increase household access to clean and affordable energy to 100% by 2030.

Gender inequalities and marginalization issues
Although the access rate to electricity is relatively high at 87%, rural electrification rate stands at 83% compared to urban regions with above 95% (4). 90% of the total rural energy for cooking and heating in Eswatini is primarily collected and used by women (5, 9).

Investment opportunities introduction
Substantial investment opportunities exist for solar PV and bagasse generation as seen in electricity authority's intention to roll out three more 15 MW solar projects and a 40 MW biomass plant (10).

Key bottlenecks introduction
Limited financial resources of the primary utility company to implement solutions constrains alternative energy production. Additionally, the current tariff system is not based on cost of service delivery and electricity access is constrained by high tariffs (7).

Market Risks & Scale Obstacles

Business - Supply Chain Constraints

Biomass energy can generally only be produced for eight months of the year in Eswatini and is vulnerable to climatic conditions, such as droughts and fire that might lead to a decrease of supply in bagasse of sugar-based by-products, potentially requiring imports of biomass supply (29, 30).

Market - Highly Regulated

The policy and regulatory framework for renewable energy production is under development with the blending mandate for bio-fuel and pricing for bagasse co-generation under review, presenting bureaucratic red tapes to investors.

Impact Case

Read about impact metrics and social and environmental risks of the investment opportunity.

Sustainable Development Need

The majority of Eswatini's energy is imported from South Africa that relies on fossil fuels for its energy production, which contributes to the country's indirect carbon footprint (9) and highlights the need for increased domestic production capacity.

Eswatini's energy sector is vulnerable to external shocks as a result of its heavy reliance on energy imports and energy sources such as hydro and biomass that are impacted by drought and other climatic factors, highlighting the need for more reliable sources of energy (17).

Eswatini's growing population size, coupled with the rising demand for fuelwood and poor management of indigenous forests, has resulted in biodiversity loss, deforestation and fuel wood resources being depleted in certain areas (9).

Gender & Marginalisation

Around 90% of Eswatini's rural population relies on fuel from wood for heating and cooking, which contributes significantly to GHG emissions and is detrimental to human health, solidifying the need for clean and affordable energy for low-income households (5, 9).

For the rural poor, grid connection costs exceed present consumption needs. These costs are an often insurmountable barrier for those who are energy poor (9); domestic energy generation from renewable resources is expected to drive down electrification costs currently reliant on fossil fuel imports.

Expected Development Outcome

Biomass energy generation reduces Eswatini's dependency on energy imports and contributes to the overall reduction of Eswatini's GHG emissions (9).

Biomass energy generation leads to increased access to clean energy sources, which reduces reliance on wood fuel and charcoal for cooking and heating, and enables restoration of indigenous forests, ecosystems and land in Eswatini (9).

Biomass energy generation leads to improved waste management and power reliability for producers in the sugar and forestry industries, capitalizing on the country's renewable biomass potential reaching around 170 MW between the sugar and timber industries (14).

Gender & Marginalisation

Increased access to clean and affordable energy through biomass energy generation reduces the use of traditional household fuels, especially wood, charcoal and dung, by rural and vulnerable households, reducing health risks and emissions (15).

Ethanol production through biomass plants can create jobs and opportunities for smallholder farmers in rural areas where poverty is concentrated and employment opportunities are most needed (9).

Directly impacted stakeholders

People

The general population enjoys lower electricity costs and reduced dependency on wood fuel for cooking and heating.

Gender inequality and/or marginalization

Low-income rural households benefit from reduced energy tariffs and obtain alternatives to using wood fuel for heating and cooking, causing less harm to their health and the environments they live in (9).

Planet

The environment benefits from increased usage of bio-energy solutions that reduce burning activities of conventional sugar farming and reduce overall carbon footprint of Eswatini, mitigating the energy sector's impact on climate change (9).

Corporates

Companies in the sugar and forestry industry obtain opportunities for additional income generating activities from biogas cogeneration and biofuel production, and become energy sufficient, which reduces costs (18).

Public sector

The government benefits from a reduced dependency on energy imports, consequently lowering annual public expenditure and strengthening fiscal consolidation.

Indirectly impacted stakeholders

People

Communities around plants obtain job opportunities, as one 15 MW biomass plant creates around 300 jobs (19).

Gender inequality and/or marginalization

Small- and medium-sized sugarcane farmers in rural areas benefit from employment opportunities (9).

Planet

The planet enjoys improved land and forestry management as less people rely on fuelwood for their energy requirements.

Outcome Risks

Despite its renewable energy character, burning of biomass for energy generation releases carbon dioxide, contributing greenhouse gas emissions in the energy sector (20).

The expansion of monocrops such as sugarcane and forestry plantations, required as inputs for biomass energy generation, may worsen soil degradation and negatively impact fragile ecosystems (9).

Forestry and sugarcane traditionally require large areas of land for cultivation; increased production thereof could restrict access to land by smallholder farmers (9).

Impact Risks

Co-production of energy from agricultural bi-products relies on success of farms and is therefore vulnerable to external factors, such as climatic conditions and market conditions, which may limit the expected impact.

If biomass energy production does not lead to reduced energy costs and increased connectivity, the rural energy crisis will not be adequately addressed and the expected impact may be limited (9).

If the sugar and forestry industry support imported energy rather than cogenerated power from bagasse boilers, due to historically cheaper prices, the expected impact may be limited (20).
