Energy Transfer will add 240,000 barrels per day of ethane export capacity at its Nederland NGL Export Terminal, with the entire volume already committed under long-term agreements running into the 2040s. The Dallas-based midstream operator confirmed the expansion in a June 18, 2026 press release, alongside 55,000 bpd of additional LPG capacity at the same site.
The Nederland NGL Export Terminal sits on the Sabine-Neches Waterway between Beaumont and Port Arthur, Texas, and has exported more than 430 million barrels of ethane since Energy Transfer began shipping from the site in 2021. The scale of this commitment is what separates it from routine capacity announcements: contracting 100% of new ethane volume through the 2040s means buyers are underwriting Gulf Coast supply on a 15-plus year view, not hedging against a short-term price window.
Nederland NGL Export Terminal Expansion Details
The project extends beyond dock capacity. Energy Transfer will expand its Mont Belvieu to Nederland NGL export pipeline to support the increased refrigeration load, and will construct two additional NGL ship docks at the terminal. Combined, these additions are designed to move the extra ethane and LPG volumes from Mont Belvieu’s fractionation complex to tidewater.
Dock capacity, not fractionation, has been the practical ceiling on US NGL exports for several years. Fractionation plants at Mont Belvieu can process ethane and LPG faster than Gulf Coast terminals can load it onto ships, so a two-dock addition at the Nederland NGL Export Terminal directly targets the bottleneck rather than adding capacity upstream of where the constraint actually sits.
Refrigerated storage is expanding in parallel. Previously announced upgrades will lift Nederland’s refrigerated propane and butane tank capacity to 1.2 million barrels and 0.8 million barrels respectively, targeted for the first half of 2027. Paired with the terminal’s existing 1.3 million barrel refrigerated ethane tank, this gives the site the largest refrigerated storage capacity for each of these products of any export complex on the US Gulf Coast.
Nederland NGL Export Terminal Timeline: 2027 to 2029
The Nederland NGL Export Terminal expansion enters service in stages starting in 2028, with the two new ship docks scheduled for completion in mid-2029. Energy Transfer is running a second, separate expansion in parallel at its Marcus Hook NGL Export Facility in Pennsylvania, lifting that terminal’s capacity to 420,000 bpd by mid-2027.
| Facility | Current Focus | Post-Expansion Capacity | Target Completion |
|---|---|---|---|
| Nederland (ethane) | +240,000 bpd ethane | Refrigerated NGL export >1.25 million bpd | Docks: mid-2029 |
| Nederland (LPG) | +55,000 bpd LPG | Propane tank: 1.2m bbl / Butane tank: 0.8m bbl | Tanks: H1 2027 |
| Marcus Hook (Pennsylvania) | NGL export expansion | 420,000 bpd | Mid-2027 |
| Combined total | Nederland + Marcus Hook | Approximately 1.7 million bpd | Full build-out by 2029 |
Running the two projects on staggered timelines rather than a single combined build lets Energy Transfer bring the lower-cost, faster Marcus Hook capacity online first in 2027, while the more complex Nederland dock construction absorbs the additional 18 months it needs. That sequencing matters for buyers planning shipping schedules against contracted volumes over the next three years.
What the Expansion Means for 2026 NGL Export Demand
The 100% subscription rate on the new ethane capacity points to buyers underwriting long-run petrochemical feedstock demand rather than short-term arbitrage. Ethane exports feed steam crackers in Europe and Asia that convert the feedstock into ethylene, the building block for polyethylene production, and cracker operators typically only sign multi-decade offtake once they’ve committed capital to the plant itself. A fully subscribed 240,000 bpd tranche running into the 2040s is a proxy for confirmed cracker investment on the buyer side, not just terminal-side optimism.
Energy Transfer operates roughly 140,000 miles of pipeline across 44 states, giving it wellhead-to-water reach that few US midstream operators can match. The Nederland NGL Export Terminal expansion reinforces that position specifically on the export side, where Gulf Coast terminal capacity has become the binding constraint on how much US NGL production can reach international buyers, a dynamic also playing out across the wider LPG terminal operator landscape as 2026 export commitments continue to outpace new dock construction.
Terminal operators and EPC contractors bidding into Gulf Coast expansion work should expect the Nederland project, alongside Marcus Hook, to keep dock construction and refrigerated tank fabrication capacity tight through 2029.
How much ethane export capacity is Energy Transfer adding at Nederland?
Energy Transfer is adding 240,000 barrels per day of ethane export capacity, plus 55,000 bpd of additional LPG capacity, at its Nederland NGL Export Terminal.
Is the new Nederland export capacity already under contract?
Yes. 100% of the new ethane export capacity has been committed under long-term agreements running into the 2040s.
When will the Nederland expansion be complete?
The project enters service in stages starting in 2028, with the two new NGL ship docks scheduled for completion in mid-2029.
What will Energy Transfer’s total NGL export capacity be after the Nederland and Marcus Hook expansions?
Combining Nederland’s post-expansion capacity of over 1.25 million bpd with Marcus Hook’s 420,000 bpd (after its mid-2027 expansion), Energy Transfer’s total refrigerated NGL export capacity will reach approximately 1.7 million bpd.
Why is dock capacity the main constraint on Gulf Coast NGL exports?
Fractionation plants at hubs like Mont Belvieu can typically process ethane and LPG faster than Gulf Coast terminals can load it onto ships, making ship dock capacity, not fractionation, the binding constraint on export volumes.
