Most public utilities have a contract obligation to always have an extra 10% extra supply over demand. How does that factor into this study?

Your talk helped me understand the likely demise of the nuclear power in California. i do now that on plant had a leak and expensive fix whereas the other plant reason for shutdown was cited that it could not compete with natural gas prices. it lead to the wonderment whether California tax payers were left down by trying to pay the lowest price but really nuclear power should have a much longer supply contract which is not tied to the cheapest price of any fuel? Any comments for those who know the answer?

I don’t think it had anything to do with leaks and as to costs, it’s more about the value of the gas power plants. The gas power plants can load follow easily. This gives them an advantage as they can make use of the low generation periods of renewables. When this happens they can quickly adjust output and make use of the higher prices in those periods. Flexible power (like gas) is also a fundamental need in variable renewable grids as it can fill the gaps of renewable generation. Oh and gas plants are really cheap (as long as gas is cheap that is lol). Nuclear plants that have already been built have around the same LCOE as gas but it can’t run at the same high profit margins as gas. TL:DR profit is pretty much the only factor here, not costs.

The assumption that the base solar and wind stay constant is not likely. They are decommissioning the early wind and solar farms at 20-25 years of time. I cannot comment on why they get decommissioned as to whether obsolete technology or uneconomic technology or just wore out?

It's energy reduction that matters first, refrigeration biggest one by far 3900 twh of electricity. Airjoule is the solution to reducing cooling energy loads by 75% and can eliminate refrigerants while making fresh water. These units are in production, company just went public, big boys like ge bought in heavy, they're running with the biggest players in the game catl, Bosch, and carrier paid huge to be first to manufacture using their tech. This isn't hype, it's going to be everywhere within the decade because if you can make an AC unit, fridge, heat pump etc, be 75% more efficient than everyone else and make clean water... Btw translate the savings airjoule would do to our energy grid and that equates to a reductio of over 1 billion tonnes of carbon. Hoping like-minded people find this and like me want to invest in these companies not just for profit but for humanities success. AIRJ / AIRJW for those interested

@18:40 “I used to think this was the point when solar and wind would … takeover”, ie LCOE solar-wind lower than coal. How can someone representing themselves as a national energy expert ever have held such a view about intermittent power? The realization does not require some vast new data set. How is this statement different from claiming, ‘I used to think there was no winter long nights, no weeks of wind doldrums’?
