Santos is leaning harder into LNG portfolio trading, not just Australia and Papua New Guinea equity production. On 15 September 2026 it said it lined up a 10-year delivered-ex-ship supply arrangement with POSCO Steel and a separate heads of agreement to buy about 1 million tonnes a year from the proposed Ksi Lisims project in British Columbia for up to 20 years from around 2031.
What happened
Under the POSCO Steel terms, Santos will deliver LNG on a delivered-ex-ship basis for a decade, drawing cargoes from its diversified global LNG portfolio. First deliveries are slated for 2030 or 2031. Santos is not tying the Korean buyer to a single upstream field; it is selling portfolio flexibility across Australian, PNG, and third-party barrels.
In parallel, Santos agreed commercial terms with Western LNG around Ksi Lisims, a proposed floating LNG project on Nisga’a Nation land in northwest British Columbia. Santos would purchase roughly 1 mtpa on a free-on-board basis for as long as 20 years, with supply expected around 2031 if the deal reaches a binding sales and purchase agreement and the project takes final investment decision. Developers design Ksi Lisims as a 12 mtpa facility drawing heavily on hydroelectric power, which they present as a lower-lifecycle-emissions path versus older liquefaction fleets.
Western LNG and partners say the Santos HOA adds to existing SPAs with Shell, TotalEnergies, and Uniper covering 6 mtpa, and that they still aim to finish commercializing the full 12 mtpa nameplate this year. The Canadian leg remains subject to definitive documentation and corporate approvals. Santos CEO Kevin Gallagher cast both moves as growth and diversification of a global LNG book that serves Asian energy demand. Shares were little changed versus the broader Australian market.
Why it matters
Asian buyers still want long-dated LNG cover, but they increasingly prefer counterparties that can optimize cargoes across basins. A DES sale into Korea from a multi-source book is that product. For Santos, locking a steel-sector industrial customer into the early 2030s extends visibility beyond the current Barossa and PNG ramp and supports midstream and trading optionality across equity and purchased LNG.
The Canadian purchase is the strategic hinge. FOB volumes from British Columbia give Santos Atlantic and Pacific routing choices once cargoes leave the terminal, and a hedge against concentration risk in Australia-PNG feed gas and shipping windows. It also shows Canadian west-coast LNG is still finding creditworthy Asian-facing merchants even as North American projects compete for offtakers and pipeline certainty.
Across the Energy & Power complex, the pair of deals shows how portfolio aggregators sit between resource owners and industrial demand. Steelmakers, utilities, and traders care about the same variables: 2030-2031 start dates, DES versus FOB risk allocation, and whether Canadian hydro-linked liquefaction can clear FID with enough contracted volume. Price risk remains. Oil-linked and hub-linked contracts still reprice with lags, and 2030s deliveries will clear into a market shaped by Qatari expansions, US Gulf projects, and Asian demand elasticity. What changes is counterparty structure: more buyers want flexible DES from diversified books, and more sellers pre-place Canadian swing volumes with merchants who already sell into Korea and Japan.
Who feels it
Korean industrial gas buyers and POSCO-linked steel operations gain another long-dated DES path into the early 2030s. Santos equity holders get longer commercial visibility, but only if HOAs convert and portfolio procurement stays margin-positive after shipping and credit costs.
Canadian upstream producers feeding Rockies and related systems, plus Nisga’a Nation and British Columbia stakeholders around Pearse Island, feel commercialization momentum if Santos and peer SPAs help Ksi Lisims clear FID. Competing developers in the US Gulf, Qatar, and East Africa see another data point that Asian offtake is still available, but often routed through merchants that already own Asian customer relationships.
Shipowners and DES operators should watch Santos portfolio cargoes into Korea from 2030. FOB Canadian purchases imply different ton-mile exposure than purely Australia-PNG DES. EPC and floating-LNG specialists tied to Ksi Lisims care whether the remaining nameplate finds bankable buyers before commercialization targets slip. Peers in the Chemicals & Materials chain that sell into steel also sit downstream of Korean energy-security choices when DES cover supports furnace utilization planning.
What to watch
First, conversion risk. The Ksi Lisims arrangement is still a heads of agreement pending SPA and approvals; POSCO volumes, pricing formula, and destination flexibility were not fully detailed in public summaries. Watch for a firmer Santos ASX update once SPAs are signed.
Second, British Columbia execution. Pipeline feed, environmental assessment outcomes, floating liquefaction schedule, and hydro power contracting will decide whether 2031 FOB supply is real. Project materials on the Ksi Lisims LNG project page remain the cleanest official window into nameplate design, location, and proponent structure as commercialization closes.
Third, Santos portfolio balance: how much equity LNG from Barossa, PNG LNG, and a possible Papua LNG FID sits behind DES sales versus how much third-party FOB gas the book must carry. The spread between purchase FOB and sale DES is where merchant value is made or lost. Fourth, Asian industrial offtake into 2030-2031. If more steel and chemical majors follow POSCO with DES portfolio contracts, Australia-based merchants gain pricing power; if buyers wait for spot or shorter deals, HOAs may stall. London morning open remains the right window to mark Canadian FID headlines against JKM and TTF.
