The signal
Time-of-use and real-time electricity rates are spreading, and more appliances can connect to utility price signals. Most households still pay a flat rate and have few smart devices.
Where it could lead
Shifting when we use power is cheaper than building new power plants for peak demand. Millions of devices acting together can function like a large virtual power plant.
Evidence that would strengthen the case
- Utilities offer simple real-time rates that devices can read automatically
- Common standards so any appliance can respond to prices
- Households see real savings without effort
What could prevent it
- Customers fear bill surprises and stay on flat rates
- Device makers and utilities never agree on standards
- Savings are too small to bother with
