I thought the gas was coming from Indonesia.....
Could be. I also heard that it was coming from Russia.
But I'm somewhat familiar with the Peruvian gas project, and it was always intended, or hoped, that it would export to California by way of Sempra. Its been a long haul, but the pipeline is built. Now they are trying to kick off the LNG plant.
Maybe in planning their project, Sempra didn't put all their eggs in one basket. It could be they have contracts with more than one supplier.
