Executive Summary
An independent Western Cape has the potential to achieve energy independence from South Africa in oil and gas, leveraging offshore discoveries like Brulpadda and Luiperd, potential shale gas in the Karoo, and strategic infrastructure such as the Saldanha Bay and Cape Town ports.
In a post-separation scenario where South Africa may restrict fuel or gas supplies, the Western Cape could achieve a local-to-import ratio of up to 50:50 for liquid fuels and natural gas within a 10-year window (2025–2035) by accelerating resource development and securing alternative import routes.
Political stability and a business-friendly regulatory framework are critical to attracting the $1–2 billion in foreign direct investment (FDI) needed for offshore projects. Integration with renewable energy, such as solar and wind-powered electric vehicles (EVs) and industrial heating, can reduce oil and gas demand, enhancing energy security.
This white paper outlines the resource base, infrastructure needs, policy strategies, and challenges to achieving oil and gas independence, providing a roadmap for stakeholders.
1. Introduction
Energy independence in oil and gas is vital for an independent Western Cape, particularly if political separation from South Africa leads to restricted fuel and gas supplies. The Western Cape, home to 7.5 million people (30% of South Africa’s population) and contributing 13.7% to national GDP, relies heavily on imported liquid fuels (75% of South Africa’s needs) and limited local gas production. With strategic assets like the Astron Energy refinery in Cape Town, the PetroSA Gas-to-Liquids (GTL) facility in Mossel Bay, and offshore discoveries in the Outeniqua Basin, the province is well-positioned to reduce dependency on South Africa.
This white paper explores how an independent Western Cape can achieve energy independence through oil and gas, focusing on local production, import diversification, and demand reduction via renewable energy integration. It estimates a local-to-import ratio over a 10-year horizon (2025–2035) and addresses geopolitical and economic challenges in a post-separation context.
2. The Western Cape’s Oil and Gas Landscape
2.1. Current Dependency
The Western Cape’s oil and gas sector is characterized by high import reliance:
- Liquid Fuels: South Africa produces ~108,000 barrels per day (bpd) of liquid fuels, mostly synthetic fuels from coal and gas. The Western Cape’s Astron Energy refinery (100,000 bpd, Cape Town) processes primarily imported crude, while the PetroSA GTL plant (36,000 bpd equivalent, Mossel Bay) operates at 55% capacity due to depleted local gas fields. The province’s fuel demand is estimated at 150,000 bpd, based on its share of national consumption.
- Natural Gas: Gas demand for power and industry is projected at 50–100 million standard cubic feet per day (mmscf/d), driven by initiatives like the Saldanha Bay Industrial Development Zone (IDZ). Current supply is limited to dwindling offshore fields and minimal LNG imports.
2.2. Post-Separation Risks
If South Africa adopts a hardline stance post-separation, restricting fuel or gas supplies from inland refineries (e.g., Natref in Sasolburg) or pipelines, the Western Cape would face significant challenges. The province’s deep-water ports in Saldanha Bay and Cape Town provide access to global markets, but rapid development of local resources and alternative import routes is essential to mitigate supply disruptions.
3. Oil and Gas Resources in the Western Cape
3.1. Offshore Discoveries: Brulpadda and Luiperd
The Outeniqua Basin, 150–175 km off the Western Cape coast, hosts significant gas and condensate discoveries in Block 11B/12B:
- Resource Estimates: Brulpadda holds an estimated 1 billion barrels of oil equivalent (BOE), with Luiperd adding comparable reserves. The basin may contain 27 billion barrels of oil and 60 trillion cubic feet (Tcf) of gas.
- Production Potential: Peak production is estimated at 73,000 BOE/d for Brulpadda and 44,000–68,000 BOE/d for Luiperd, achievable in phased developments. By 2030–2032, these fields could supply the Mossel Bay GTL plant (36,000 bpd) and gas-to-power projects (50–100 mmscf/d), covering significant portions of fuel and gas demand.
- Challenges: TotalEnergies and CNRI’s withdrawal in 2024 due to commercial and regulatory issues delayed progress. Africa Energy Corp., the new operator, requires $1–2 billion in investment and a 5–7-year timeline to reach production.
3.2. Shale Gas in the Karoo Basin
The Karoo Basin, partially within the Western Cape, holds 20–30 Tcf of technically recoverable shale gas. Exploration is in early stages, with environmental opposition and water scarcity posing barriers. Aggressive policy support could yield 10–20 mmscf/d by 2035, supporting industrial and power applications.
3.3. Infrastructure Assets
- Astron Energy Refinery: Processes 100,000 bpd, primarily imported crude. An independent Western Cape could secure alternative crude supplies via Saldanha Bay or Cape Town ports.
- PetroSA GTL Plant: Reviving this facility with gas from Brulpadda/Luiperd could restore 36,000 bpd output, meeting ~25% of liquid fuel demand.
- Saldanha Bay IDZ: Planned LNG import terminals and a proposed Saldanha-Atlantis-Cape Town pipeline could distribute 50–100 mmscf/d, enabling gas-to-power (500–1,000 MW) and industrial growth (e.g., 13,000 jobs).
4. Estimating the Local-to-Import Ratio (2025–2035)
4.1. Demand Projections
- Liquid Fuels: The Western Cape’s fuel demand is ~150,000 bpd, driven by transport, industry, and agriculture.
- Natural Gas: Demand for power and industry is 50–100 mmscf/d, based on Saldanha IDZ and gas-to-power projects.
4.2. Production Scenarios
- Optimistic Scenario (2035):
- Offshore Gas: Brulpadda and Luiperd produce 100,000–150,000 BOE/d by 2030–2032, supplying the Mossel Bay GTL plant (36,000 bpd) and gas-to-power (50–100 mmscf/d). This meets 40–50% of liquid fuel demand (60,000–75,000 bpd) and 30–50% of gas demand (15–50 mmscf/d).
- Shale Gas: Contributes 10–20 mmscf/d, enhancing gas supply.
- Local-to-Import Ratio: 40:60 to 50:50 for liquid fuels; 30:70 to 50:50 for gas.
- Pessimistic Scenario (2035):
- Offshore Gas: Delays push production beyond 2035, with the Mossel Bay GTL plant at 10,000–15,000 bpd. Gas-to-power relies on LNG imports.
- Shale Gas: No significant production due to regulatory and environmental hurdles.
- Local-to-Import Ratio: 15:85 to 20:80 for liquid fuels; 5:95 to 10:90 for gas.
4.3. Import Strategies
To bridge the gap, the Western Cape must diversify imports:
- LNG Imports: Saldanha Bay and Cape Town ports could import 50–100 mmscf/d from Mozambique (projected to dominate African LNG by 2030) or global suppliers like Qatar and Australia.
- Crude Oil Imports: The Astron refinery can process crude from Middle Eastern or African markets, facilitated by Saldanha’s deep-water port and free port status.
- Integration with Renewable Energy to Reduce Oil and Gas Demand
Renewable energy can reduce reliance on oil and gas by replacing demand in specific sectors, enhancing energy independence:
- Electric Vehicles (EVs): The Western Cape’s solar potential (2,000 kWh/m²/year) and wind resources could power EV charging infrastructure, reducing transport fuel demand by 20–30% by 2035. For example, scaling EV adoption to 100,000 vehicles could cut liquid fuel needs by ~10,000 bpd.
- Industrial Heating: Solar thermal and biomass systems can replace gas in industrial processes (e.g., ceramics), potentially reducing gas demand by 10–20 mmscf/d in Saldanha IDZ.
- Gas-to-Power Complement: Gas turbines (e.g., Ankerlig, 1,338 MW) provide peaking power to stabilize renewable-heavy grids, allowing solar and wind to displace gas in electricity generation while maintaining reliability.
By prioritizing renewables for transport and industrial applications, the Western Cape can lower its oil and gas demand, making the 50:50 local-to-import ratio more achievable.
