Low Natural Gas prices are good for consumers, suck for producers. If NY wants to spend NY taxes on keeping nuclear plants open and reducing the demand for NG or Coal, it is possible that will depress those markets a little, which means cheaper NG and Coal. For Texas power consumers, that depends on how your power is produced if there might be any benefit. For Texas Natural Gas producers lower prices mean less revenue, less incentive to drill, and perhaps fewer jobs.
That's what I am thinking too, incrementally pretty small. Since natural gas demand in the Northeast region is more affecting production in the Marcellus which is the local source, it is likely to be minimal impact for down south.
Coal is another thing altogether.
