About as good as a natural gas or oil well with a frozen well head. Except a broom won't fix a well head.

This weather screws most everything up.

They have been pumping oil and gas at -50 for years. As long as you keep it flowing it will not freeze. Trans Alaska Pipeline is not heat traced.

From CNBC "ENERGY U.S. oil wells, refineries shut as winter storm hits energy sector"

My post was somewhat tongue in check but it is warmer in Alaska now than in some of Texas. The Alaska pipe line was designed for these temps, the oil infrastructure in Texas is not.

This to will pass.

The T-A pipeline heats the oil at the first pump station.

I have worked at Pump 1, they do heat some of the oil. The oil coming from North Star is heated because it comes from a man made island about 10 miles away and about 5 miles of the pipe is under the arctic ocean, but the oil comes out of the ground at around 130 F and is over a 100F when it enters the TAP's. Flow Rates keep it heated on its journey to Valdez.

The reason refineries in areas where they were not designed for the cold shut in, is the instrumentation impulse lines freeze, 3/8" 1/2" tubing that has no heat trace, with out these permissive's things shut down.

There are no oil and gas well heads “froze.”
Have no idea what your taking about.

But Texas’ much touted “25,000 mw of wind “capacity” ( capacity being the keyword, not output) is sitting at 4,500 mw right now and that’s double what it was yesterday.
Yesterday they were over 15,000 mw’s short on supply vs demand.
The power prices down there are still maxed out at $9,000 per mw.
For reference a typical large coal fired plant can produce each mw for around $25 to $30/mw.

I am not in the business, but these is from an email I got yesterday from our gas utility in Tulsa, Oklahoma.

"Why has this weather caused so many problems?
Due to the unprecedented, historically low temperatures over an extended period, we are seeing much higher natural gas use coupled with supply issues. As of this morning, our suppliers of natural gas are experiencing freezing gas wells due to the duration of the extreme cold. This is impacting the amount of gas they are able to provide to us."

I would think the same would be true in Texas.

They are freezing because they are not heat traced and insulated, gas does have condensates that will freeze, in the tubing impulse lines that runs to Pressure Transmitters and Flow Transmitters, if you use Tube Bundle that is insulated and heat traced this would not be happening, Prudhoe Bay Alaska processes more cubic feet of gas a day then any field in north America and the 50 Mega Watt Central Power Station runs on fuel gas, gas runs through a knock out drum that separates the condensates out. I have seen 35 to 45 below 95 below chill factor for weeks on end and everything keeps running. There is no way in hell a wind turbine could operate in these temperatures, and Solar! no sun for 3 months

Looks like swapping the battery out rather than charging it is the way of the future. Might work in populated areas, can't see it working to well in remote areas.

"Electric Cars can be designed to allow a fast battery swap, exchanging your battery for a fully charged battery in less than half the time it takes to refill a gas tank. This offers Tesla Model S drivers an even faster option when recharging while driving long distances."

Still haven't figured out where all the electricity is going to come from.

Jim,

You are right, no such thing as perpetual motion, at least not yet, it still takes HP or KW to move an object.
