Falling battery costs make hybrid projects more valuable than standalone solar by improving grid reliability and reducing exposure to negative power prices.
why would they remove the law ? here in australia we’ve been slowly moving towards more and more negative pricing as coal gets pushed out and has to bid negative to ensure power is still taken by the market
These requirements have helped mitigate renewables curtailment in China. However, they have also increased operational costs for renewable energy projects, and many project owners have reported low utilization rates of their storage systems.
Since introduced in 2022, policy mandates requiring solar and wind energy projects to include energy storage systems have been crucial in the acceleration of storage deployment in China.
interesting, i suspect when they run into the same problem we did (prices going negative in the middle of the day) it’ll be back again but without gov mandate required
I don’t know if you misunderstood me but I agreed with you, I said it’s good they installed batteries to soak up excess renewables with the catch that as they continue to install more wind and solar they will need more battery to soak it up
You make it sound like the problem is solved, they no longer need to install any more batteries, they have enough (forever), problem solved
Funny because if I remember correctly China just removed that law. They had that requirement for years.
Nice to see other areas are getting started on curtailment problems from lack of planning.

this has made straight solar largely uneconomical so the majority of new projects are solar/battery hybrids
To install solar quicker and free up battery production for EVs. When you have enough EVs plugged in the EVs become the battery storage.

They avoided the problem years ago. That’s why they don’t need the law anymore.
They need to lower the price of batteries again. So that is what China is doing again.
You’re concerned about a problem that has already been solved. Just not every government had a plan or asked China how China already solved it.
How did they solve the problem of excess daytime solar?
With batteries. That they installed. Required by law.
How did you miss the entire point?
