Texas electric prices have been capped at $9000/MWHr for the last few days. Average is about $35/MWhr. The Texas electric bill is about $10 billion per day right now.
When this winter storm set in, I switched from grid power to my natural gas generator. I have a 48kW Generac attached to a 1000 gallon natural gas tank. The tank also feeds all my gas appliances and fireplaces in my home. At the current rate of usage, I have another 24 days on which to operate.
Where most people are paying enormous rates, I purchased my whole tank of gas for $940, plus delivery fee.
I have strongly recommended to my friends to have generators installed and to buy their own natural gas storage tanks to power them. While my personal setup was about $20,000 fully installed and hooked up, you can easily get a 24kW model that would power most homes 2000-2500 sq. ft. easily, for about $7000-$9000.
Best part is, many whole home generator providers will allow you to finance if the upfront costs are too burdensome.
So natural gas spot prices have gone from around $3-MMBTU to like $350-MMBTU and there is 30GW of electrical generating capacity offline.
