Golden Triangle Polymers, a world-scale ethane cracker under construction in Orange, TX, has been delayed by at least six months, pushing back a key source of new US ethane demand.
The project, a joint venture between Chevron Phillips Chemical (CPChem; 51%) and QatarEnergy (49%), is now expected to start up in 2027, according to the developers. The original start-up target was 1H26.
Golden Triangle Polymers will include a 2 Mtpa ethane cracker and two 1 Mtpa high-density polyethylene units. Once fully operational, the project will consume roughly 110 Mb/d of ethane.
The delay shifts the trajectory of domestic ethane consumption, pushing back what would have been a step-change in Gulf Coast demand. The chart above shows the revised forecast in East Daley Analytics’ Ethane Supply & Demand report. The postponement results in a flatter near-term demand profile through 2026, with consumption ultimately catching up once the project comes online in 2027.
Located in the Golden Triangle petrochemical corridor northeast of Mont Belvieu, the facility is expected to draw heavily on Mont Belvieu-linked supply, making its startup timing relevant to the broader US ethane balance.
The delay will extend the period when domestic ethane consumption is insufficient to fully absorb available supply. This results in more ethane in the system in 2H26, likely softening Mont Belvieu prices relative to prior expectations and delaying price support into 2027.
See East Daley’s Ethane Supply & Demand report for more details. In the near term, export markets should be able to absorb a portion of the incremental supply, particularly as Phase 2 of Enterprise’s (EPD) Neches River terminal is expected online soon. – Sam Chen Tickers: COP, CVX, EPD.

The Permian Basin’s next big buildout is already taking shape, but this time the driver isn’t crude oil. In The Permian Basin at a Crossroads: Why This Pipeline Boom is Different, East Daley Analytics’ latest white paper reveals how gas demand from AI data centers, utilities and LNG exports is rewriting the midstream playbook in the leading US basin. Over 10 Bcf/d of new capacity and $12 billion in investments are reshaping flows, turning the Permian into a gas powerhouse even as rigs decline. Read Part II: Why This Pipeline Boom is Different
