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 Contributors (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

Capital - Limited Investor Interest

The business model for solar home systems (SHS) in rural areas has brought little uptake by private investors in Eswatini due to affordability concerns by end-users (15).

Capital - Requires Subsidy

Solar home systems (SHS) for rural households require some form of financial support system for end-users or increased access to credit to make it affordable for households in need (15), hence limiting the market size potential for investors.

Market - Highly Regulated

Eswatini is yet to establish a regulatory framework for off-grid solar energy solutions; the Energy Regulatory Authority is currently formulating a licensing scheme, which will allow licensing for up to 1 MW for own use consumers (17).

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.

The growing population in Eswatini, coupled with the rising demand for fuelwood and poor management of indigenous forests, has resulted in biomass resources being depleted in certain areas of the country (9, requiring alternative sources for energy generation.

Eswatini lacks critical water, sanitation and hygiene infrastructure in hospitals and education facilities, with 9 out of 10 clinics in the country lacking access to hot water for operations and cleaning instruments (25).

Gender & Marginalisation

275,000 households (23% of population) in rural areas of Eswatini are not connected to the national grid and have no access to energy because it is more expensive than biomass alternatives such as firewood (15).

For the rural poor, grid connection costs exceed present consumption needs. These costs are an often insurmountable barrier for those who are energy poor, regardless of whether the electricity provided is from renewable or fossil fuel generated sources (9).

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).

Expected Development Outcome

Off-grid solar power solutions reduce the overall energy demand from the grid of households and businesses, which results in lower energy import needs (15).

Increased access to solar powered clean energy sources through off-grid systems reduces reliance on wood, fuel and charcoal for cooking and heating, lowering emissions and preserving ecosystems and land in Eswatini (9).

Gender & Marginalisation

Access to off-grid solar power solutions addresses challenges associated with health, hardships and inconveniences resulting from the use of solid fuels for cooking and heating at household level, particularly in rural areas (9).

Off-grid solar power solutions present a more affordable alternative to increase rural electrification compared to grid infrastructure extension and increase access to energy in the most remote areas.
