Santos Ltd (ASX: STO) shares are up 2.7% in afternoon trade at $7.18 per share.
The S&P/ASX 200 Index (ASX: XJO) energy company is among the minority of stocks in the benchmark index posting solid gains in 2022.
That's largely thanks to soaring global oil and gas prices, offering the company some heady profits on its domestic sales and international exports.
But Santos shares could come under pressure if its international exports are curtailed.
What are the concerns over the gas trigger?
You've probably heard of the gas trigger.
It's part of the Australian Domestic Gas Security Mechanism. And it enables the government to compel the major liquid natural gas (LNG) exporters to curtail some of their exports from their Queensland plants in favour of selling into the Australian market in case of an energy crisis.
That energy crisis is now upon us, with Victoria facing a gas crunch through the end of September. And as The Australian reports, the Gladstone LNG project – controlled by Santos alongside its partners Petronas, Total and Kogas – wants the emergency gas legislation amended.
Gladstone is the only LNG project that's exporting gas from the domestic market. That means unlike the LNG projects owned by the other two top producers – Origin Energy Ltd (ASX: ORG) and Shell, which are both net contributors to the domestic market – Santos' project is in net deficit.
In a nutshell that means if the gas trigger is pulled, the onus may fall entirely on Gladstone to sell extra gas into the Aussie market to stave off an energy crisis.
Though Santos has yet to comment, The Australian reported on sources indicating Santos' Gladstone LNG project wants the net contributor part of the gas trigger abolished, as it doesn't account for the fact its gas has already been contracted to overseas customers.
The energy security mechanism was slated to end in December this year, but Resources Minister Madeleine King said earlier this month that it will be extended to 2030.
