https://www.zerohedge.com/markets/tesla-nio-ev-charging-stat… The sprawling municipality of Chengdu in Sichuan province and nearby Chongqing (all located in southwestern China) – where scorching heatwaves and lack of rainfall slashed hydropower generation, resulting in weeks of power rationings at some of the largest factories in the country, have reportedly spread to EV charging stations.
Bloomberg reported that some Tesla Inc. and Nio Inc. charging stations in Chengdu and Chongqing (both metro areas have a combined +46 million people) had been turned off because of power conservation measures, leaving drivers unable to charge their EVs.
The impacts have also led to power cuts for manufacturers, including Toyota Motor Corp. and battery producer Contemporary Amperex Technology Co., which have shuttered operations.
I can not do justice to this topic, but about a month ago we had the topic here of China’s costs for electricity being inside out because the state was subsidizing coal? and for some reasons if the subsidies were taken off the cost of manufactured goods would soar so the Chinese government had put in factory quotas?
The entire apparatus of the communist party is falling apart. The peg to the USD is driving a huge wedge down on the entire idea of a Chinese economy that has no basis in reality. Back to the stone ages with Xi making control laws for the public.
zerohedge is giving idiotic advice to the Chinese:
“With an unstable power grid, China’s race to electrify its future with EVs will be challenging. The only way for a stable grid is nuclear power.”
Jaak
How many countries depend on nuclear power for more than 60% of their electricity: Only France
However, currently France’s nuclear power production is much less than 60% of their capacity. France is currently importing massive amounts of electricity from it neighbors.
With an unstable power grid, China’s race to electrify its future with EVs will be challenging.
The effect of renewable energy incorporation on power grid stability and resilience
Smith et al. www.science.org/doi/10.1126/sciadv.abj6734
Abstract:
Contemporary proliferation of renewable power generation is causing an overhaul in the topology, composition, and dynamics of electrical grids. These low-output, intermittent generators are widely distributed throughout the grid, including at the household level. It is critical for the function of modern power infrastructure to understand how this increasingly distributed layout affects network stability and resilience. This paper uses dynamical models, household power consumption, and photovoltaic generation data to show how these characteristics vary with the level of distribution.
It is shown that resilience exhibits daily oscillations as the grid’s effective structure and the power demand fluctuate. This can lead to a substantial decrease in grid resilience, explained by periods of highly clustered generator output. Moreover, the addition of batteries, while enabling consumer self-sufficiency, fails to ameliorate these problems. The methodology identifies a grid’s susceptibility to disruption resulting from its network structure and modes of operation.

==============================
DB2,
Your referenece source is not related to China. And zerohedge is wrong about China having an unstable power grid. Coal dominates China’s grid. China’s grid is not dominated by intermittent wind and solar as shown in the following numbers:
China does not have a wind and solar dominated power grid.
Coal - 62.2%
Nat gas - 3.2%
Nuclear - 4.8%
Renewables - 29.8% (wind 5.5% and solar 3.1%)
California has much more renewable dominated power grid than China.
Fossil fuel - 42%
Nuclear - 10%
Renewables - 48%
No grid stability and resiliance problems in California.
Power generation scientists and engineers say that 80% renewables are easy and 100% is doable. Rememeber that energy storage systems like batteries make the grid more stable and resilient than nuclear power.

True. And neither is this, but it is important to our futures.
Reserve margin may need to rise to 300% by 2040 as more renewables added to grid: ISO New England www.utilitydive.com/news/new-england-future-grid-study-iso/6…
The reserve margin on the ISO New England system may need to increase from about 15% to 300% by 2040 in some scenarios, as more renewables are added and dispatchable generation is retired to meet state clean energy goals, according to a July 29 report from the grid operator.
The first phase of the ISO’s Future Grid Reliability Study models a variety of decarbonization scenarios in 2040 and concludes they “may require a significant amount of gas or stored fuels to support variable resources.”
A scenario where reliability criteria are met using only solar, wind and storage, would challenge the transmission system and require “an outsized amount of land or offshore areas” for wind and solar farms, the report found.

========================================
This is the worst case scenario. This scenario does not include biomass/waste energy, hydro energy, geothermal energy, and grid upgrades for power imports from outside ISO New England.
Odds are we end up with a very deflationary energy policy. The public will buy in and buy in again.
Besides we just got past our 90 F days here in CT. I have never seen it this hot. The most ardent deniers are changing their minds, “it(climate change) is here”.
