What would change this answer
The verdict is borderline in the specific sense that this analysis cannot determine which side of the line the project falls on.
The verdict is borderline, and it is borderline in the specific sense that this analysis cannot determine which side of the line the project falls on. The band across inputs nobody has measured runs from 11.1% to 19.3%, and the wider band including the contract terms runs from 2.8% to 25.0%. What follows is what moves it, in the order the answers should be bought.
Take-or-pay is the largest single mover and the one most likely to fail. At the brief's own 60% the project returns 2.8%; at 73.3% it reaches the 8% floor; at 88.6% the 13% bar; at full nameplate 16.3%. Nothing else in the case has that range, and it is settled by one term in one term sheet.
An upgrading capital cost at the client's level rather than the published benchmark takes the case to 25.0%, a clear Go on its own. That is a three-quotation question and it is the cheapest large mover in the plan.
A Thai wheeling charge above $2.87/MMBtu, or a refusal on cross-border biomethane injection, moves it to No-Go, because the remaining route does not clear at any price the market pays. So does an offtake at the brief's own 60% minimum take, on any route, which makes the take-or-pay level the single most decision-relevant term in the contract and the one the plan has never modeled.
A price above $18.89 clears the hurdle on the current cost stack without anything else changing. Whether that is available is the one question only a counterparty can answer.
Section added · The brief's borderline band demands that a verdict name which lever, by how much, and on what evidence; that belongs in its own section rather than inside the verdict
