Texas has been adding storage to the grid, they have 8gw now, and are projected to have 18gw by the end of the year. Batteries are pretty instant recovery. The original plan I saw was to distribute them around the grid specifically for grid regulation purposes because they have some pretty remote areas, and long stretches that have frequency issues.
The second issue they have is they are putting solar out west, and most of the population is in central or on the east coast, and actually most of the use is probably around houston so they are looking at what 500 miles. Houston has grid issues, I don’t know why they have been resisting solar.
Batteries are instant, and most other forms of energy have a spin up time. Most likely his paper isn’t right.
if you are looking at purely frequency regulation, his paper is probably correct. IF you are looking at grid management as a whole. It is less likely because ultimately you don’t need to load follow which is a guessing game as to what future demand will be because it takes time for new generation to come online. Do you need a hot spare gigawatt power plant if you have a 8 gigawatt hour battery system? it buy 8 hours to start up a gigawatt power plant. If you have 100mw/hrs of batteries, you can tighten the margins of extra capacity available in case of a surge in demand. So instead of say 5%, you can cut that right down to 1%. any surge gets picked up by the battery until extra generation can come online.
The point is you are eliminating the guesswork which saves money, and you don’t have to have extra generation online which saves money even if you never use the batteries. However, it does hurt the power generation company’s bottomline.
Hi All
I just changed the engine oil on the wife’s 2022 Toyota Highlander Hybrid.
Sheee . . . one year now she has had this 40 mpg fuel sipper. She’s put 30,000 miles on it in the last 12 months. (Why will not this be 70 y.o. nurse just retire, eh?)
Anyhow I have been bumping up the in-the-US specified 0W-16 oil to a premium 0W-20.
No problems, no issues at all created.
Now I’ve just watched this video:
Modern Suburu lovers especially need to watch and listen to this guy well.
And those with cylinder deactivation systems need to search out defeat options.
Same with the majority of the run-stop systems.
Will I ever bump up to a 5W-20 oil on her car??? Maybe. Maybe not. It actually runs the engine only partial time; so the average engine temperature is low-low. NOT a modern expected constant oil thinning high temperature. And even with Toyota’s dual direct and port injection systems I am seeing, smelling accumulative gasoline fuel dilution of the engine oil. Crazy, foolish to go with long oil change intervals on this system!
For sure DIY your own oil changes to get back control, and decisions.
And this is what I believe sincerely DIY using wood-for-your-power is all about. Seizing back some control and responsibly for your Life.
