Automated Demand Response

Traditional demand response calls a factory manager who manually shuts down a production line. Automated demand response (ADR) sends a price signal to a smart thermostat that adjusts by 2 degrees without anyone noticing. The difference is not just convenience; it is the difference between a resource that responds a few times per year and one that responds thousands of times.

ADR uses communication protocols (primarily OpenADR) to send price or grid signals directly to building management systems, smart appliances, EV chargers, and industrial controls. The device responds automatically based on pre-programmed rules. No phone call, no human decision. Response times drop from hours to seconds, and participation costs drop from "dedicated staff" to "initial configuration."

Scale through aggregation. A single smart thermostat shifts 1-2 kW. A million enrolled thermostats shift 1-2 GW, comparable to a large power plant. Google Nest's Rush Hour Rewards program enrolls millions of thermostats that automatically pre-cool homes before peak hours and reduce cooling during peaks, delivering hundreds of megawatts of demand reduction.

Why isn't ADR already replacing peaker plants?

Three barriers. Enrollment is voluntary; most customers never opt in. Baseline measurement is difficult (how much would the customer have consumed without the signal?). And utility revenue models in many states still reward selling more electricity, creating institutional resistance to programs that reduce sales. The technology works. The business model and regulatory framework lag behind the hardware.
