As someone in New England: We don't have enough gas infrastructure up here either, you can't just add more gas plants to our grid and accomplish anything.

As it is, in the coldest periods of winter you will at times see the ISO-NE grid running on 40% oil because we don't have enough natural gas pipeline capacity to run all of the gas plants and meet natural gas heating demands. So many of the gas plants have to kick back over to burning oil.
