For those asking about LNG (US GC assets) selling extra gas...
They might not be able to. I've been working with a couple of LNG guys and the bigger issue is FERC allows you to draw a yearly rate, divided by 365. If you don't pull your rate for that day, you might be able to go a little higher the next day, but essentially it is a "use it or lose it" number.
So to increase the amount you could make, you need to ask FERC (and PHSMA, however you spell it) for permission to increase your yearly rate (which in turn affects your daily rate).
So if your site can process 85 MMSCFD of gas, that's actually 31.025 BCF/a. You go down for 3 days because of a refrigerant compressor seal, you just lost out on a tanker (or 2) of LNG.
And unlike other O&G facilities, you have to go back for federal approval to increase production. For example, if you have space on your environmental permit and want to produce more NH3 (ammonia), you can. Assume your equipment can handle it. No additional approvals needed (as was the case with a previous client as well). They went from 100% to 110% after doing a performance test. But if Cheniere wants to go to 110% of their daily rate, they can't. Unless they have approval from FERC.
