Even if they're all on by 6:30, that gives the power plant time to ramp up production to meet demand from 5:30-6:30.
If everything is synchronized and everyone in a region starts drawing lots of power at the exact same time, the line voltage on the grid will suddenly drop below safety thresholds and could trigger a brownout for that whole region. The point being, randomizing power draw over a period of time allows the grid more time to match demand.
- pdonis 4y ago> that gives the power plant time to ramp up production to meet demand But the capacity isn't there, at least not if the article's primary claim is correct: "the peak demands are concentrated primarily when renewable energy is unavailable" It doesn't seem like the availability of renewable energy will be much better at 6:30 vs. 5:30 or 6:00. So once all the demand is ramped up, there would still be a capacity shortfall.
- naasking 4y agoI'm saying that even if the power were there, these smart thermostats would still strain the grid by turning on all at exactly the same time. Power coming from renewables can exacerbate the problem, thus requiring grid storage, but the problem remains even without them.
