Natural Gas use for electricity by region is also quite variant. Texas, California, and Florida are by far the largest users with 28.31%,13.74% and 10.42% respectively (those 3 states have > 52% of total in US with 25.74% of population).
Repeating the above analysis (on colder than expected winter) in Northeast, the block of Maine, NH,CT,MA,RI, and VT uses 1.18%,.56%,.83%,3.3%,.82% and 0% respectively for a total of 6.69% of nations nat gas for electricity usage. Adding NY at 5.08% the entire northeast block is 11.77% of total while having 11.72% of population. The bottom line then is that nat gas for home heating is where New England has an advantage (well, if you call using heating oil an advantage...but methinks this winter it will be...)
Good research and analysis.

Lets breakdown the annual use into seasonal usage for electric fuel.

The Northeast utilities are winter peakers meaning that their natural gas usage for electric generation will be higher in the winter than in the summer.

The Biggest users (CA, TX, and FL) are summer peakers and use their gas as electric fuel during the summers for air conditioning.

Looks like the point is that the fuel oil users need to keep the tank topped up this winter.  If there is a gas delivery problem, the electricity is at risk in the NE.
