Greetings JAGStorm, this Texas mess is truly a disaster... MY friend lives there and he has had a pretty chilly life recently..
He is a survivalist type of guy, ex military, and he even said it was "good" for him to go through it, to "test" methods and equipment out in case of
a long power outage, etc.
There were "mandates" out to utilities in Texas to NOT use certain power assets, due to greenhouse gases etc, This was a federal mandate. Essentially,
certain power sources were not allowed to be used or "dispatched" for load demands. (So, in some sense, it WAS a political mandate that contributed to
the frozen mess.)
Texas was also the victim of too much "green energy" being injected into the power sources for the region.
The wind and solar are great things; as long as the weather conditions are within tolerances for the two types of green energy.
The wind must be above a certain velocity for them to generate power, but if the wind reaches a certain higher velocity, the windmills MUST shut down,
and "feather" their props, because the bearings and generator can't handle those extra load forces on them.
The solar, of course, needs the sun, so if cloudy, or night, ZERO power output... or dang near zero if cloudy.
I have worked in the utility business all of my working life, and am familiar with Megawatt hours and prices and how they change drastically in just a
24 hour period.
In Australia, not too long ago, the state of South Australia got hit with a statewide blackout. The perfect storm hit, too cloudy for solar to work ,
and too windy for windmills to operate; combines with not enough power sources to rely on that weren't inclimate weather tolerant.
When a power company builds it power "portfolio", it needs to be very diverse, and robust. If a power company puts too much into the green energy type
of power sources; those green sources can become a liability if you are hit with the right conditions to take them out, and not have enough "other"
sources of power generation to bring online to meet load demand.
The price for megawatts can be very volatile... and the introduction of all of this "green energy" has been a giant factor in this volitility.
When the sun goes down, or the wind stops, these power assets become money chewers, and electricity eaters, as back up power needs, and piping heating
needs, keeping an energy source in standby or shut down mode.
When you overload your power sources with too much "green" energy, you face MASSIVE load swings in demand over a 24 hr period. These demands must be
switched back and forth amongst your power assets. Hydro, Gas fired, coal fired, solar, and wind power. In these over load situations is when the
price goes negative. It balances out with the super high prices, or TRIES to; but in some situations you get hit with a prolonged high price period
and then all the customers get bled dry.
I can't help but wonder if it isn't some sort of a scheme for some of those evil elite.
What I am meaning is.... Like a lot of people make a LOT of money betting on the highs and lows of the stock market, is there ALSO a thing like that
See where I am coming from? There was something that was tried a while back, never hit off to a great start, it was called "Carbon Credits"... Al Gore
was big on it, of course his "investments" were in green energy... hmmm McFly, seeing the picture some these turds paint?
I have seen the price of megawatt hour go from an actual negative price, to over several THOUSAND dollars in the course of a single day!
We almost always drop load when prices go low.... but sometimes the green energy overloads the system... where you need to either disconnect the green
from the grid, or else shut down coal fired for example.
And to RESTART coal fired station you burn FUEL OIL in your ignitors, and boiler pre-warming oil fire "guns". This costs HUGE dollars. At $1.45 per
litre for diesel fuel... it is not uncommon to burn through a FEW million dollars in fuel oil, especially if there is a prolonged turbine warming
wait, if the turbine was COLD and on turning gear for a long time prior to unit start up.
So it is cheaper in the long run to keep the unit online, at a very reduced load, or turbine off line, and spinning, but the generator is off line...
not synched, and then you are "bypassing" the turbine, and just recycling every bit of steam and water in a loop, until you need the power again. This
also is quite expensive, as you are running big pumps, (11KV motors, etc) chewing upon power just keeping things idling along.
Our power dispatchers work hard to balance these power assets, to try and keep the prices down in Oz, and my company is a basically nonprofit, or
small profit for the state government...
You can't shut down coal fired stations, which typically are your "BASE LOAD" units; and you fine tune your grid with hydros, and gas fired units to
make up the day to day deviations in demand.
The TRUE PROBLEM is that now, and as you are seeing in Texas and other places; is that they have removed too much of that base load by shutting down
power plants, or injecting into the grid system too high of a percentage of "green" power where it becomes the overwhelming driving economic factor in
And when a natural, or man made disaster comes along, as Texas is getting hit with.. you can't simply "flip a switch" and get big coal fired units
back in the game of supplying power.
They take many hours, and sometimes up to 36 hours, up to several DAYS to go from cold start up to online at full load. By then, your national
infrastructure is already damaged and burnt toast, or frozen cryogenically!
The huge extremes in power prices have been induced by too much green energy in national grids.
While this may or may not be good for the environment, it truly does wreak havoc in the economic swings of power provision to a country.
Even natural gas fired units which are extremely popular these days, as they can come online and be at full load in like half an hour or so... you
have that entire infrastructure that is needed to "support" them too. Mainly wells, and pipelines. Where does that gas come from? FRACKING mainly! And
we know what that does to water tables, and fault lines. Plus they STILL pump out CO2 when they are running. They are basically jet airplane engines
attached to generators.
In Oz they tend sit off line when all the green energy is in play...and when prices go high, they come online, and skim off the "cream" from the power
milk. This causes the big generators, usually coal fired units, to "lose out" on those high prices to offset the time when they operate at a financial
When the LOSSES outweighs the profits, they sell off, or shut down permanently the coal fired units. Which creates a big vacuum vortex, and removes
them from what is called "spinning reserve power sources".
And I am wondering if this "volatility" is somehow now being used as another way to "milk the herd" of their money??
Sorry to be so long winded but it is a intense topic with many contributing factors, of which I only touched on briefly.
