One of the least expensive ways to integrate more renewables into our energy system is to orchestrate large electrical loads in buildings.

While thermostats have been getting all the press, anyone who has experienced a 2- or 4-degree temperature rise on a hot day knows that comfort is impacted. But some loads, such as water heaters, can be orchestrated to turn on at the right time — not at random times, as they have traditionally done — without sacrificing comfort. Orchestrating California’s 13 million+ water heaters to run during peak solar-generation hours would make a significant impact.

Open-standard solutions are critical to cost-effective appliance orchestration. Tucson Electric Power’s Project RAIN (Resource Aggregation and Integration Network) showed how open standards ease the installation and orchestration of common consumer devices and distributed energy resources (DER) such as thermostats, water heaters, electric vehicle (EV) chargers, battery storage, and solar.

This webinar covered:

  • How the OpenADR and CTA-2045 open standards work together to support appliance control
  • Real-world implementation of an appliance orchestration system at Tucson Electric Power
  • The state of the art in appliance orchestration and value to the grid:
    • Increasing resilience
    • Supporting increased renewables
    • Supporting future microgrid capability
  • Lessons for the future
