Angola LNG Operations: 5.2 mtpa Plant and Expansion Plans

Plant Overview

Angola LNG is located at Soyo in Zaire Province, at the mouth of the Congo River. The facility is operated by Angola LNG Limited, a Chevron-led consortium, and represents the country’s sole liquefied natural gas export infrastructure. The plant’s nameplate capacity stands at 5.2 million tonnes per year (mtpa) of LNG, equivalent to approximately 250 billion cubic feet (Bcf) per year of liquefaction capacity, with gas processing capacity of 1.1 billion cubic feet per day.

The Utilisation Gap

Prior to 2024, the Soyo plant operated at approximately 70% of nameplate capacity, averaging around 700 million standard cubic feet per day against a designed throughput of 1.1 billion cubic feet per day. This utilisation gap was caused by declining gas production at the mature associated-gas fields that supply the plant. As Angola’s oil production declined, so did the associated gas volumes that were routed to Soyo rather than flared.

The gap represented both a problem and an opportunity. A problem because the plant’s economics — particularly the return on the substantial capital invested in liquefaction infrastructure — depend on throughput. An opportunity because significant spare capacity existed to absorb new gas supply without building additional trains.

Sanha Lean Gas Connection: The Game Changer

The most significant operational development at Angola LNG in recent years has been the Sanha Lean Gas Connection, which achieved first gas in 2024. The project connects lean gas production from the Sanha field complex to the Soyo plant via a new pipeline system.

Key parameters:

• Initial production: Approximately 80 million standard cubic feet per day
• Impact at full capacity: Will fill roughly 40% of the plant’s processing capacity
• Supply duration: Engineered to supply gas for 15 years
• Status: Operational since 2024, ramping up

The Sanha connection is transformative because it provides a dedicated, long-term gas supply stream independent of declining associated gas from oil production. This decouples the LNG plant’s performance from Angola’s crude oil decline curve and places the facility on a more stable footing.

New Gas Consortium

A separate New Gas Consortium completed agreements in 2024 and is expected to achieve first production in 2025. This consortium brings together multiple operators to aggregate gas supplies from various blocks and route them to Soyo. The consortium was over 50% complete as of late 2024.

Combined with the Sanha connection, the New Gas Consortium will move the Soyo plant from chronic undersupply toward full utilisation — and potentially beyond, raising the question of expansion.

November 2025 Production Record

In November 2025, Angola LNG recorded a 20% increase in production, reaching total output of 5.23 million barrels of oil equivalent for the month. The daily average of 174,456 barrels of oil equivalent — of which 147,358 boe/day was LNG — demonstrated the impact of the new gas supply connections coming online.

This performance validated the investment thesis behind the Sanha Lean Gas Connection and the New Gas Consortium. For the first time, the Soyo plant was operating near its designed capacity, with the production record coming as new gas volumes filled the previously underutilised infrastructure.

Expansion Under Consideration

With gas supply approaching nameplate capacity, Angola LNG’s operator began weighing expansion options. In November 2024, the consortium announced it was considering adding capacity — either one additional full-scale train or a smaller “mini train” of approximately 3 mtpa. Either option would lift total plant capacity toward 8 mtpa.

A final investment decision has not been announced. The expansion depends on:

1. Confirmation that gas supply will sustainably exceed current capacity
2. Acceptable LNG market conditions and pricing
3. Financing arrangements — the original plant was a multi-billion dollar construction project
4. Regulatory approval from ANPG

Export Markets: Europe Dominant

In 2023, Angola LNG exported approximately 175 billion cubic feet of LNG, with a market pattern heavily weighted toward Europe:

The European concentration reflects both geography — Angola is closer to European markets than to East Asian buyers, reducing shipping costs — and the post-2022 surge in European LNG demand following the reduction of Russian pipeline gas. France and the United Kingdom are the top European destinations, where Angola’s cargoes compete with those from Nigeria LNG, Algeria, Qatar, and US Gulf Coast terminals.

India absorbs approximately 35 billion cubic feet, making it the largest single Asian buyer. As India’s LNG import capacity grows and long-term contracts are renegotiated, Angola may seek to diversify its export portfolio toward Asian markets where pricing can be more favourable.

Northern Gas Complex (Eni)

Beyond the Chevron-led Angola LNG operations, Eni is developing the Northern Gas Complex — a separate gas gathering and processing system comprising two offshore platforms, an onshore gas-processing plant, and pipelines connecting to the Soyo LNG terminal. At peak production, the Northern Gas Complex is designed to deliver approximately 141 billion cubic feet per year of processed gas.

This project is significant because it represents additional supply infrastructure feeding into the Soyo terminal, further supporting the case for capacity expansion. The Northern Gas Complex also aligns with Angola’s broader gas monetisation strategy of reducing flaring and capturing associated gas for commercial use.

Strategic Significance for Angola

LNG operations occupy a critical position in Angola’s energy strategy for several reasons:

1. Revenue diversification within hydrocarbons: Gas revenues provide a partial hedge against crude oil price volatility, as LNG pricing is increasingly delinked from oil benchmarks
2. Reduced flaring: Routing associated gas to Soyo rather than flaring it addresses environmental commitments and captures economic value from a resource previously wasted
3. Industrial development: The Soyo complex anchors an industrial zone that supports employment and local content development in Zaire Province
4. Energy security: Domestic gas can be directed to power generation and industrial use, reducing fuel import dependency
5. Transition positioning: LNG is positioned as a “bridge fuel” in the global energy transition, potentially giving Angola’s gas assets a longer commercial runway than its crude oil reserves

Relationship to Domestic Gas Use

Angola’s gas monetisation strategy involves balancing LNG exports against growing domestic gas demand. The government has articulated plans for gas-to-power projects, petrochemical feedstock supply, and industrial gas use that would compete with LNG exports for available supply. The expansion of Soyo’s capacity must be calibrated against these domestic requirements.

Outlook

The trajectory for Angola LNG is positive. After years of underperformance driven by inadequate gas supply, the plant is now moving toward full utilisation. The expansion study signals operator confidence in sustained gas availability, and the European and Indian market positions provide reliable offtake. Key metrics to watch include monthly production rates, expansion FID timing, and the ramp-up profile of the Northern Gas Complex.

Operational Performance and Export Markets

Angola LNG Limited, operated by Chevron at the Soyo complex, processes gas through a facility with 1.1 Bcf/day processing capacity and 250 Bcf/year liquefaction capacity (approximately 5.2 mtpa). In 2023, total LNG exports reached 175 Bcf, with European markets receiving 75% of output (primarily France and the United Kingdom) and Asia-Pacific taking 25% (with India receiving approximately 35 Bcf).

New Gas Supply Connections

The facility’s historical constraint of operating at approximately 70% of nameplate capacity, averaging about 700 million scf/day due to declining gas production at mature fields, is being addressed through multiple new supply connections. The Sanha Lean Gas Connection achieved first gas in 2024 at approximately 80 million scf/day, expected to fill roughly 40% of plant capacity and sustain supply for 15 years. A new gas consortium, over 50% complete in 2024, targets first production in 2025.

Eni’s Northern Gas Complex adds substantial new supply through two offshore platforms, an onshore gas-processing plant, and pipelines connecting to Soyo, with projected peak production of approximately 141 Bcf per year. These new connections support the November 2024 consideration of expanding Soyo with one additional liquefaction train or a 3 mtpa mini-train, reflecting growing confidence in upstream gas availability.

Dual Role in Export Revenue and Domestic Power

Angola LNG serves a dual strategic function: generating export revenue from international gas markets while providing the gas supply foundation for domestic natural gas power generation. The Angola Energia 2025 framework specifically evaluated gas from Soyo for electricity generation locally and through LNG distribution to Luanda, Benguela, and Namibe, enabling gas logistics infrastructure that supports broader industrialization under the PDN 2023-2027.

Broader Economic and Institutional Context

Angola’s petroleum sector operates within the institutional framework established by the PDN 2023-2027, which targets total GDP of 62 trillion kwanzas, annual growth of approximately 3.3%, and non-oil GDP growth of approximately 5% annually. The plan’s three fundamental pillars of human capital development, infrastructure modernization, and economic diversification all depend on sustained petroleum revenue. Public debt reduction from over 100% of GDP in 2020 to just above 60% in 2024 demonstrates fiscal discipline, while agriculture’s share of GDP more than doubled from 6.2% in 2010 to 14.9% in 2023, showing that diversification is progressing alongside oil sector development. The Estrategia de Longo Prazo Angola 2050 envisions growing non-oil GDP from USD 84 billion to USD 275 billion and non-oil exports from USD 5 billion to USD 64 billion by 2050, with the petroleum sector providing the transitional revenue base for this transformation. The Kwenda social program, which distributed USD 420 million to 251,000 families under the previous PDN, illustrates how oil revenue translates into direct social investment that builds the human capital foundation for long-term economic diversification. The current plan’s alignment with the African Union Agenda 2063 and the UN Sustainable Development Goals 2030 further reinforces the connection between petroleum sector performance and broader development outcomes, with 75% of the PDN’s 284 action priorities directly impacting the 17 SDGs.

Downstream Integration and Refinery Development

Angola’s petroleum sector strategy increasingly links upstream production to downstream processing through three major refinery projects. The Cabinda Refinery, inaugurated on 1 September 2025, operates at 30,000 b/d Phase 1 capacity with Phase 2 expansion to 60,000 b/d expected within 18-24 months, representing a USD 550 million investment with Gemcorp holding 90% and Sonangol 10%. The Lobito Refinery, at approximately 12% completion, targets 200,000 b/d capacity with a total investment of USD 6.6 billion and a USD 4.8 billion financing gap being discussed with ICBC, Societe Generale, Standard Chartered, and Afreximbank. The Soyo refinery remains on hold with an earliest expected online date of 2028. Together, these projects address Angola’s approximately 72% import dependency for refined petroleum products, equivalent to roughly 3.3 million metric tons annually.

Export Markets and European Energy Security

In 2023, Angola LNG exported 175 Bcf, with 75% directed to Europe (primarily France and the United Kingdom) and 25% to Asia-Pacific (India received approximately 35 Bcf). This European export concentration positions Angola as a significant contributor to European energy security.
