Managing an integrated grid using household solar and battery as part of the supply management is one thing.
Adjusting people's usage for demand management is another.
They need to be separated and managed differently.
Instead of push adjusting HVAC for demand, they could use proper price signals with the appropriate local automation at the household that can be over-ridden by the consumer.
I agree price signals and local automation are the way to go.
I would love to have my HVAC run according to the true cost of electricity, also minimizing CO2 emissions.
BUT giving the grid operators emergency control over demand is a useful tool when the grid is close to failure. Too many people will just hit override unless the price signals are very high. When grid operators know people will die if their system goes down and it’s on the brink, people choosing to be 4 degrees cooler is such an immoral choice I’m OK removing that choice from them.
Also very helpful to reduce shocks to the system after any outages by temporarily limiting HVAC restarts.
> Too many people will just hit override unless the price signals are very high.
But that's the point of an energy market, it will adapt the price signal to the supply and the demand.
People will override it without thinking only the first time. The second time they will remember the humongous bill they got because of that and will think twice.
