Definitely agree on having diversity in winter heating.
This past winter when NG flows into New England peaked the Electric Producers were all hit with Operational Flow Orders and had to switch to Oil or whatever. This was to protect the NG heating consumer. But NG prices still spiked, and so did Electric when those plants that could not swap to expensive oil came offline. Folks in N.E. don't know how close they came to rotating regional wide blackouts.
The good thing is several entities are permitting and building new pipelines from Penn to NJ, NY & NE, but don't think for a moment the local heating consumer is the reason. The real Golden Goose is the LNG transfer facilities that will load & ship our LNG to a very gas hungry Europe. Projections are for approx 20-40% NG price climb as the spread narrows between US & Euro.
For anecdotal, read the recent post from an Aussie who mentions it already happening down under:

So bottom line,... stay diversified my friend.
