Singapore: who buys, how much, at what price, and by when
The sandbox is smaller than its headline megawatts suggest, it allocates to generators rather than suppliers, and nobody has quoted the price the brief assumes.
Singapore's Energy Market Authority and Economic Development Board launched a biomethane import sandbox on 27 October 2025, described as up to 300 MW of capacity, to test commercial viability before wider deployment (EMA). A closed call for proposals followed in September 2025, inviting power generating companies to bid by 1 December, with award scheduled for 28 February 2026. The quota called for is 18 million MMBtu, with the first 10% of molecules to be delivered by 2030 (S&P Global).
Three features of that structure matter more than the headline.
The call went to generators, not to suppliers. The 300 MW is allocated to power generating companies acting as trade aggregators. Salerno would not hold sandbox quota; it would sell to a company that does. Its route to market runs through a Singapore generator's procurement decision, not through a regulator's allocation.
The quota and the capacity describe different sizes. Three hundred megawatts at 53% net generating efficiency and an 85% capacity factor burns 39,401 MMBtu a day, which is 851 tonnes a day of biomethane. The 18 million MMBtu quota would sustain that for 1.25 years. Spread over the eight- to ten-year term the brief itself contemplates, the quota is 107 tonnes a day. A supplier sizing a fifteen-year project against "300 MW of demand" is sizing against a number the scheme has not committed to buy. On the quota basis, the brief's 200 tonne-per-day target is 187% of the entire pilot.
The award has not been published. We searched for the outcome of the 28 February 2026 award by name and against the regulator's own newsroom, and found no announcement of which generators were allocated quota or in what volumes. That is a searched absence rather than an unsearched one, and it means the amount of the pilot still open to a new supplier is genuinely unknown rather than known to be large.
Two demand pools sit beside the sandbox and are not subject to its quota.
Singapore opened applications in December for at least 200 MW of new data-center capacity, of which at least half must come from eligible green pathways, with biomethane explicitly among them (Data Center Dynamics; Argus). And Singapore's LNG bunker market reached 571,400 tonnes in 2025, up 24%, with biofuel blends at 1.36 million tonnes, up 54% (Ship & Bunker). That bunker pool is 1,565 tonnes a day of LNG, larger than the sandbox burn, and it is driven by maritime fuel regulation that already binds rather than by a pilot that may not be renewed. It is also the pool a pipeline cannot serve, because a bunker customer needs liquid fuel alongside a ship.
On price, the $20 bundled figure is the brief's own hard assumption and no counterparty in the inputs has quoted it. Two external anchors bracket it. Global average biomethane production cost via upgrading is around $19/MMBtu, and in Southeast Asia the premium over fossil gas runs to roughly 100% (3Degrees). In Rotterdam, subsidized bio-LNG bunker fuel was assessed at EUR 23.45/MMBtu, a EUR 13.83 premium over conventional LNG (Argus). Twenty dollars is plausible. It is not evidenced.
