The energy architecture of the Southern African Development Community (SADC) is undergoing a paradigm shift, characterized by the intersection of geological maturity in legacy gas fields and the nascent emergence of the Rovuma Basin as a global liquefied natural gas (LNG) hub. At the center of this transition lies the Republic of Mozambique Pipeline Investments Company (ROMPCO), a joint venture that has facilitated the cross-border flow of natural gas for over two decades. However, the impending "gas cliff"—a term describing the rapid depletion of the Pande and Temane fields—now threatens the industrial viability of the South African economy and the fiscal stability of Mozambique. This report provides an exhaustive analysis of the historical, corporate, technical, and geopolitical dimensions of this energy nexus, evaluating the pathways toward 2035.
The monetization of Mozambique’s natural gas reserves began not as a commercial inevitability, but as a high-risk strategic gamble by Sasol and the governments of the region. Although the Pande field was discovered in 1961 and Temane in 1967, the resources remained "stranded" for decades due to the prolonged Mozambican Civil War and the lack of a viable domestic or regional market.[1] The cessation of hostilities and the subsequent democratization of South Africa in the 1990s created a unique window for regional energy integration.
In October 2000, the Republic of South Africa and the Republic of Mozambique signed a landmark Cross-Border Agreement.[2, 3] This intergovernmental treaty established the legal and regulatory framework necessary to authorize ROMPCO to construct, own, and operate the Mozambique-Secunda Pipeline (MSP). The agreement was foundational, as it provided the sovereign guarantees and harmonized regulatory environment required to attract project finance for a cross-border asset in a post-conflict zone. Sasol initially assumed 100% of the investment risk, fast-tracking development to satisfy the fuel requirements of its petrochemical complexes in Secunda and Sasolburg.[4]
The technical execution of the MSP involved the construction of an 865-kilometer, 26-inch diameter high-pressure steel pipeline.[2, 4] The Mozambican section spans 525 kilometers from the Central Processing Facility (CPF) in Inhambane to the border at Ressano Garcia, while the South African portion continues to Secunda, feeding into an extensive inland distribution network.[4] Completed in 2004, the pipeline initially had a design capacity of 120 million gigajoules per year (MGJ/year), which has since been significantly expanded.
| Component | Specification/Status | Relevance |
|---|---|---|
| Total Length | 865 Kilometers | Connects Inhambane to Secunda.[2] |
| Initial Capacity | 120 MGJ/year | Designed to meet Sasol's internal demand.[4] |
| Expanded Capacity | 212 MGJ/year | Achieved via compression and loop lines.[1] |
| Loop Line 1 | 128 Kilometers (2015) | Increased in-country pipeline capacity.[3] |
| Key Infrastructure | Komatipoort Compressor Station | Declared a National Key Point in SA.[3] |
The governance of the pipeline is a complex multi-stakeholder arrangement. In South Africa, the operation is regulated by the Gas Act 48 of 2001 and overseen by the National Energy Regulator of South Africa (NERSA), while in Mozambique, it falls under the Ministry of Mineral Resources and Energy and the Petroleum Law Nr. 21/2014.[5] This dual-regulatory oversight ensures that the pipeline serves the national interests of both states, providing Mozambique with a steady stream of royalty gas and revenue while securing South Africa’s industrial energy supply.
A pivotal shift in the ownership and control of ROMPCO occurred between 2021 and 2022. For the first seventeen years of its operation, Sasol maintained a dominant position, reflecting its role as the primary risk-taker and customer. However, as part of a group-wide asset divestment program initiated in March 2020 to reduce debt and focus on core chemical assets, Sasol announced the sale of a 30% equity interest in ROMPCO.[6]
In May 2021, Sasol’s subsidiary, Sasol South Africa (SSA), reached an agreement with a private consortium for the sale. However, the existing state-owned partners—the South African Gas Development Company (iGas) and the Companhia Moçambicana de Gasoduto (CMG)—exercised their pre-emptive rights to acquire the shares.[6] The Competition Tribunal of South Africa approved the merger in January 2022, concluding that the transaction would not lessen competition as the pipeline remains a natural monopoly.[7]
The deal reached financial close in June 2022, with iGas and CMG each acquiring an additional 15% stake for an initial R4.1 billion, plus a deferred payment of up to R1 billion contingent on milestones through June 2024.[6] This transaction effectively transitioned ROMPCO from a private-majority entity to a state-led infrastructure vehicle.
| Shareholder | Pre-Divestment Stake | Post-Divestment Stake | Parent/Government |
|---|---|---|---|
| iGas | 25% | 40% | Central Energy Fund (South Africa) [6] |
| CMG | 25% | 40% | ENH (Mozambique) [6] |
| Sasol | 50% | 20% | Sasol South Africa (Private) [5] |
The implications of this restructuring are profound. By holding 80% of the equity, the governments of South Africa and Mozambique have institutionalized their control over the region’s primary gas artery. This allows for closer alignment with national energy policies, such as South Africa’s Integrated Resource Plan (IRP) and Mozambique’s industrialization strategy. Despite its reduced equity, Sasol remains the technical operator of the pipeline, ensuring that specialized expertise is maintained while the state entities oversee strategic direction and regional integration.[2, 6]
The "gas cliff" is no longer a theoretical risk but a rapidly approaching industrial emergency. The Pande and Temane fields, which have fueled South African industry for two decades, are entering a phase of terminal decline. Sasol, as the operator of the Sasol Petroleum Temane (SPT) joint venture, has issued series of increasingly urgent warnings regarding the cessation of supply to external customers.[8, 9]
The crisis is rooted in the finite nature of the southern Mozambican reservoirs. Current projections suggest that the natural gas supply from these fields will be suspended or severely curtailed by July 2028.[8, 10] Sasol originally issued a June 2026 cutoff warning for some customers, reflecting its intent to prioritize declining volumes for its own process needs in Secunda, where gas serves as a critical feedstock for the production of synthetic liquid fuels and chemicals.[9, 11]
To mitigate the immediate impact on the South African market, Sasol has proposed a Methane-Rich Gas (MRG) solution as a temporary bridge. MRG is a by-product of Sasol’s coal-to-liquids (CTL) operations in Secunda and currently flows primarily through the Lilly pipeline to KwaZulu-Natal.[9] The proposed extension would see Sasol supply MRG to external customers from July 2028 through June 2030, effectively buying the industry an additional two years to transition to imported LNG or other sources.[12, 13]
However, the implementation of this MRG bridge is contingent on regulatory approval from NERSA. Sasol has applied for a Maximum Gas Price (MGP) that reflects the higher costs of synthetic gas production compared to conventional natural gas extraction.[12] This has created a friction point between the producer, the regulator, and industrial users, who are already grappling with rising energy costs. The Industrial Gas Users Association – Southern Africa (IGUA-SA) has welcomed the extension but warns that it does not resolve the fundamental issue of long-term security of supply.[12]
| Supply Milestone | Estimated Date | Context/Impact |
|---|---|---|
| Initial Pande-Temane Depletion | 2026 – 2027 | Sasol prioritizes internal Secunda volumes.[11] |
| End of Natural Gas for Industry | July 2028 | Primary "Gas Cliff" event.[8, 10] |
| MRG Extension (Proposed) | 2028 – 2030 | Synthetic gas bridge to buy time for LNG.[12] |
| Absolute Supply Deficit | Post-June 2030 | Total reliance on new infrastructure/imports.[12, 14] |
The "Gas Cliff" is not merely a technical shortfall but a "GDP cliff." Estimates suggest that 8% of South Africa’s national GDP depends on industries fueled by the ROMPCO pipeline, contributing approximately R700 billion annually to the economy.[15] Without an alternative supply, the country faces a catastrophic loss of output and a dramatic rise in unemployment.
In the hierarchy of solutions to the gas cliff, the Matola LNG terminal in Mozambique has emerged as the primary short-to-medium-term bridge. This project, a joint venture between TotalEnergies and the South African firm Gigajoule (operating as the Beluluane Gas Company), involves the deployment of a Floating Storage and Regasification Unit (FSRU) at the Port of Matola.[2, 11, 13]
The strategic logic of the Matola terminal is its proximity to the existing ROMPCO pipeline. By injecting regasified LNG into the MSP, the project can utilize existing transmission infrastructure to deliver gas to South African industrial hubs in Mpumalanga and Gauteng. The FSRU model offers a lower capital cost and a faster deployment timeline compared to land-based cryogenic storage.[13]
Minister of Mineral and Petroleum Resources Gwede Mantashe stated in late 2025 that the government is fast-tracking the Matola FSRU with an expected operational date in mid-2026.[11] However, industry analysts remain skeptical of this aggressive timeline. Achieving a Final Investment Decision (FID) requires the aggregation of a "demand stack"—a collective commitment from large industrial users, Eskom, and independent power producers to purchase significant volumes of gas.[12, 14]
Furthermore, the economic transition to LNG is fraught with pricing risk. Piped natural gas from Mozambique has historically been priced lower than international LNG benchmarks. Importing LNG involves a minimum $USD\,500\,million$ investment in terminal infrastructure and exposes the regional market to global price volatility.[8, 16] Estimates indicate that LNG could cost up to three times more than the current piped supply, a cost increase that many energy-intensive industries, such as steel and glass manufacturing, may be unable to absorb.[8, 13]
Given the high fixed costs and lengthy lead times of LNG, some researchers and industrial leaders are advocating for Liquefied Petroleum Gas (LPG), specifically propane, as an immediate alternative. Propane can be imported through existing terminals at Richards Bay and Saldanha, reducing the need for new $USD\,500\,million$ facilities.[8, 16] Propane is a direct replacement for natural gas in many industrial burners and provides greater financial flexibility, as it does not require 20-year offtake commitments to anchor the infrastructure.[16]
While the southern gas fields decline, Mozambique’s long-term economic future is anchored in the Rovuma Basin. The northern province of Cabo Delgado holds one of the world's largest gas discoveries, with the potential to transform Mozambique into a top-ten global LNG exporter.[17, 18] However, the $USD\,50\,billion$ investment in this region was halted in April 2021 due to a violent insurgency linked to the Islamic State.
The flagship Mozambique LNG project, operated by TotalEnergies with a 26.5% stake, is a $USD\,20\,billion$ development designed to produce 13.1 million tonnes per annum (mtpa) of LNG.[19, 20, 21] Following a successful counter-insurgency effort by Rwandan and SADC forces, the security environment was deemed sufficiently stable for a restart. In November 2025, the consortium officially lifted the Force Majeure declaration.[22, 23]
As of May 2026, the project is back in full construction mode at the Afungi site. Over 4,000 workers are currently mobilized, and the project is estimated to be 40% complete.[22, 24] The revised timeline targets first LNG production in 2029, a five-year delay from the original 2024 target.[19, 25] The restart required a significant restructuring of the $USD\,14.9\,billion$ debt package, the largest in Africa. Notably, the project partners had to provide an additional 10% in equity to replace the withdrawn support from UK Export Finance (UKEF) and the Dutch agency Atradius, which cited climate and human rights concerns.[26]
ENI has successfully pioneered the floating LNG (FLNG) model in Mozambique, which avoids the security risks associated with large-scale onshore construction. The Coral South FLNG facility has been operational since 2022, providing Mozambique with its first consistent stream of Rovuma Basin gas.[18, 27] Building on this success, ENI approved the Coral North project in late 2024. With a $USD\,7.2\,billion$ investment, Coral North is expected to begin production in 2028, doubling the consortium's output to 7 mtpa.[18, 27, 28] This project is already in the construction phase and is designed to incorporate operational improvements and higher local content participation compared to its predecessor.[27]
ExxonMobil’s Rovuma LNG project is the most ambitious of the northern developments, with a total estimated investment of $USD\,30\,billion$.[27, 29] Like TotalEnergies, ExxonMobil lifted its Force Majeure on November 20, 2025, following a reassessment of the security situation in Cabo Delgado.[27, 30]
In April 2026, ExxonMobil submitted a revised project development plan to the Mozambican government. This plan adopts a modular approach, replacing the two massive 7.6 mtpa liquefaction trains originally planned with 12 smaller modular trains of 1.5 mtpa each.[27, 30] This modular design is intended to improve commercial viability, reduce construction complexity, and increase total capacity to 18 mtpa.[30, 31] ExxonMobil is targeting a Final Investment Decision (FID) in the second half of 2026, with the goal of exporting the first gas shipment by 2030.[27, 29, 32]
| Project | Operator | Capacity | Status (May 2026) | Target First Gas |
|---|---|---|---|---|
| Mozambique LNG | TotalEnergies | 13.1 mtpa | Construction (40% complete) [19] | 2029 [22] |
| Coral South | ENI | 3.4 mtpa | Operational [27] | 2022 (Actual) |
| Coral North | ENI | 3.6 mtpa | Construction Phase [27] | 2028 [27] |
| Rovuma LNG | ExxonMobil | 18 mtpa | Pre-FID (Target H2 2026) [27] | 2030 [27] |
The optimism of the gas restart is balanced against a deepening macroeconomic crisis in Maputo. In February 2026, the IMF reclassified Mozambique’s debt from "sustainable" to "unsustainable".[33, 34] This reclassification reflects a perfect storm of factors: the long-term impact of the 2016 "tuna bond" scandal, the high costs of the Cabo Delgado insurgency, and the massive fiscal deficits resulting from the delayed LNG revenues.
The fiscal deficit widened to 6.2% of GDP in 2024, and although it narrowed to 4.5% in 2025, the government faces increasingly difficult financing conditions.[33, 35] Market spreads between Mozambican sovereign bonds and U.S. Treasuries have reached a concerning 1,185 basis points, and Fitch has downgraded the country’s rating to "CC," indicating a high risk of default or restructuring.[34]
This financial instability has several direct impacts on the gas sector: 1. Increased Financing Costs: Project lenders are likely to demand higher risk premiums or additional sovereign guarantees that the Mozambican state is currently unable to provide. 2. Strained Public-Private Partnerships: Mozambique’s national oil company, ENH, must finance its equity stakes in the mega-projects. With a debt-to-GDP ratio near 90%, the state’s ability to support its SOE is limited.[33, 34] 3. Governance and Transparency Pressures: The IMF has called for greater exchange rate flexibility and fiscal consolidation as conditions for a new program, which may create political tension as the country approaches a critical phase of project execution.[33, 35]
Despite these headwinds, the IMF notes that the LNG sector offers substantial medium-term potential to restore stability if revenues are managed through the newly established sovereign wealth fund.[33] However, the "Resource Curse" remains a significant risk, as economic growth remains heavily concentrated in capital-intensive sectors with limited formal job creation for the broader population.[36]
South Africa’s energy strategy is codified in the Integrated Resource Plan (IRP) 2025, which was approved by the Cabinet in October 2025.[37, 38] The IRP 2025 represents a R2.23 trillion investment roadmap designed to replace aging coal-fired capacity with a "Balanced Plan" that includes solar, wind, nuclear, and a significant allocation for gas-to-power.[38, 39, 40]
The IRP 2025 identifies gas-to-power as a "critical lever" for grid stability. The plan targets the procurement of 6,000 MW of new gas capacity by 2030 and an additional 12,250 MW between 2031 and 2042.[40] This capacity is essential for providing dispatchable power to manage the intermittency of the 34 GW of wind and 25 GW of solar PV also planned for 2039.[38, 39]
| Horizon | Technology | New Capacity Target |
|---|---|---|
| By 2030 | Solar PV | 11,270 MW [37] |
| By 2030 | Wind | 7,340 MW [37] |
| By 2030 | Gas-to-Power | 6,000 MW [37] |
| By 2039 | Total Gas-to-Power | 18,250 MW [40] |
| By 2039 | Nuclear | 5,200 MW [39] |
The plan’s "Gas at Risk" scenario quantifies the system's vulnerability: if the 6,000 MW of gas capacity is not operational by 2030, the retirement of 8 GW of coal plants must be delayed, or the country faces a significant risk to the security of supply.[40]
South Africa’s transition is supported by the Just Energy Transition Partnership (JETP), a $USD\,13.7\,billion$ international finance model.[41] However, the partnership faced a significant setback when the United States formally withdrew on February 28, 2025, cancelling $USD\,56\,million$ in grants and $USD\,1\,billion$ in commercial investment.[41] Despite this, the remaining International Partners Group (IPG)—including the EU, UK, France, and Germany—has reaffirmed its "strong support".[41, 42]
The inclusion of gas in the IRP 2025 is a point of contention within the JET framework. While some donors emphasize a pure renewable path, South African labor and industrial groups argue that a "Just" transition must include gas to protect the jobs of workers in energy-intensive sectors who cannot yet transition to green hydrogen or electric vehicle manufacturing.[42, 43]
The symbiotic relationship between the two countries via the ROMPCO pipeline means that the gas cliff has deep economic consequences on both sides of the border.
For South Africa, the threat is immediate and existential. Gas-dependent industries, including steel, glass, automotive, and food processing, support 75,000 direct jobs.[15] These industries contribute between R300 billion and R500 billion annually to the economy.[10, 12]
A "gas cliff" event where supply is cut off without an affordable alternative could lead to a 4% to 7% reduction in national GDP.[8, 10] The manufacturing sector, already under pressure from electricity shortages, would face "irreversible damage," potentially leading to a broader de-industrialization of the Gauteng and Mpumalanga regions.[9, 14]
For Mozambique, the economic stakes are tied to the successful execution of the northern mega-projects and the continued operation of the ROMPCO corridor. The Rovuma LNG projects are expected to generate $USD\,150\,billion$ in revenue over three decades, potentially increasing state revenues by 60%.[27]
However, the challenge of "local content"—ensuring that Mozambican companies and workers benefit from the $USD\,50\,billion$ investment—remains central. TotalEnergies has committed to a local content plan that includes up to 7,000 direct jobs for Mozambicans during construction and $USD\,4\,billion$ in contracts for local companies.[22, 44] Yet, high illiteracy rates and a lack of technical training in the northern provinces remain significant barriers to inclusive growth.[17, 45]
| Impact Category | South Africa (SA) | Mozambique (MZ) |
|---|---|---|
| Employment Risk/Gain | 75,000 industrial jobs at risk [15] | 5,000+ local construction jobs [27] |
| GDP Contribution | 8% of national GDP at risk [15] | Potential 34% GDP surge post-2030 [46] |
| Infrastructure | R2.2 trillion energy plan [38] | $USD\,50\,billion$ in LNG investments [32] |
| Revenue Target | Industrial competitiveness [43] | $USD\,150\,billion$ over 30 years [27] |
The security of the Cabo Delgado projects and the broader integration of the SADC energy market are influenced by a complex set of geopolitical actors.
The withdrawal of the SADC Mission in Mozambique (SAMIM) in July 2024 left a significant security void that was largely filled by the Rwanda Defence Force (RDF).[17, 47] Rwandan forces, which have grown to over 4,000 personnel, have been instrumental in allowing TotalEnergies and ExxonMobil to lift their Force Majeure declarations.[17, 48]
However, the mission faces a "sustainability crisis." In early 2026, Rwandan officials warned that they would withdraw their forces if international partners—specifically the European Union—did not provide "adequate and predictable" funding.[48, 49, 50] The EU’s financial support through the European Peace Facility is scheduled to end in May 2026, creating a critical deadline for the regional security architecture.[49, 50] A Rwandan withdrawal would likely lead to a resurgence of insurgent activity, potentially forcing another halt to the gas projects.
As Western investors and export credit agencies (ECAs) exhibit caution due to climate and security risks, China has aggressively expanded its role in Mozambique. This shift was marked by a comprehensive "gas and minerals deal" signed between President Daniel Chapo and President Xi Jinping.[51]
This deal represents a new model of "long-cycle sovereign integration," which combines: 1. Exploration Drilling: CNOOC is set to begin drilling in five offshore blocks in March 2026.[18, 28, 52] 2. Geoscientific Mapping: Chinese institutions are conducting systematic mineral mapping of unmapped deposits in northern Mozambique.[51] 3. Security Cooperation: China has committed to military training and equipment provision for Mozambican counterterrorism forces.[51]
By integrating energy development with security and industrial processing, Beijing is positioning itself as a more reliable and holistic partner than the Western consortia, which are often hamstrung by domestic political and environmental regulations.
The regional gas sector is at a crossroads, with three plausible scenarios defining the outlook through 2035.
In this scenario, South Africa successfully commissions the Matola LNG terminal by late 2027, anchored by a joint Eskom-Industry demand stack.[12, 14] Sasol’s MRG bridge provides a seamless transition until 2030, after which the Matola and Coega terminals provide the necessary supply for the 18,250 MW of gas-to-power capacity envisioned in the IRP 2025.[40] Mozambique successfully manages its debt crisis through a combination of IMF consolidation and the start of Area 1 and Area 4 revenues in 2029-2030.[25, 27] Regional security is maintained through a permanent, multi-state arrangement involving Rwanda and a reformed Mozambican force.[17]
In this scenario, infrastructure delays and regulatory deadlocks in South Africa prevent the commissioning of any LNG terminal before 2029. The 2028 gas cliff leads to the closure of significant parts of the South African manufacturing sector, causing a structural decline in GDP and a surge in unemployment.[9, 14, 15] Industries that survive do so by switching to more expensive and carbon-intensive diesel or limited LPG imports.[8, 16] In Mozambique, the security situation remains volatile, and the withdrawal of Rwandan forces leads to repeated project suspensions, resulting in a sovereign default on international bonds.[34, 49]
A third scenario involves the resurrection of the $USD\,8\,billion$, 2,600-kilometer African Renaissance Pipeline (ARP). This project, connecting the northern Rovuma Basin directly to South Africa, gains momentum as a Chinese-financed alternative to LNG.[53, 54] By 2035, the ARP provides 18 billion cubic meters (bcm) of gas annually, circumventing the need for maritime transport and coastal regasification.[53] This scenario sees Mozambique and South Africa deeply integrated into China’s Belt and Road Initiative, with Beijing serving as the primary financier and security guarantor for the region's energy corridor.[51]
The ROMPCO pipeline, once a predictable artery of regional commerce, has become the focal point of an urgent transition. The findings of this report emphasize that the "gas cliff" is a solvable crisis, but one that requires immediate and coordinated action across multiple jurisdictions.
The convergence of geological depletion and geopolitical competition means that the 2026-2030 period will define the economic trajectory of Southern Africa for the next quarter-century. Success depends on moving beyond "aspirational" policy documents toward the practical execution of infrastructure projects that can bridge the looming gap in the region's energy supply.
