2. In times of weather emergencies, snow and excessive cold, the gas
companies routinely shut down gas flow to non-residential areas

This is a contract issue; Commercial customers often get better rates
for being 'cutable'... but you need to assure the generator is not one.

This is true as long as no emergency is declared.  If a state of emergency
*is* declared (yes, Nortern Virginia declares a state of emergency for snow
flurries) contract or not, commercial customers get cut if the gas is needed
for residences.

On the other hand, LNG in tanks is a bit more reliable in the snow if
have a large enough tank to provide pressure during cold whether and to

LNG tanks for any big installation will be BIG. You'll have to
pay to keep all the LNG in stock. Propane has another issue --
it can get too cold for it to vaporize, leaving you really SOL.

Yes, thats why only small (again sub 65KW) installations make sense.  And
from experience, we have had -22F in Lancaster, PA and our propane genset
started right up.  That the coldest we have on record at any of our sites
though during a utility outage.
