In demand response programs, a customer agrees to reduce or shift their electrical usage in exchange for utility bill credits or other incentives. The Connectivity Standards Alliance, which runs Matter, and the non-profit OpenADR Alliance have outlined how the two protocols will work together to automate this process.
Matter will handle in-home communication between a smart, connected electrical appliance, such as an EV charger, heat pump, or solar install, and an energy gateway that collects real-time data. Then the OpenADR 3 protocol will handle communication between the gateway, utilities, and grid. This should enable an end-to-end pathway from the grid to your home’s electrical appliances.
When energy demand is high, these appliances can make small shifts or reductions in energy use, potentially via a home energy management system. For example, a freezer could delay a defrost cycle, a washing machine could wait to start a load, or a hot water tank could pause its heating.
Traditionally, DR programs have focused on HVAC systems, the largest energy consumer in your home. But by connecting more electrical appliances in people’s homes to the grid, utilities could see significant aggregate benefits. That’s been difficult so far with multiple fragmented standards, but a press release from the CSA and the OpenADR Alliance promises that the partnership should make it easier for manufacturers to develop products capable of working with DR programs and for utilities to have a “standardized, scalable mechanism for demand response.”
With the push toward electrification, connecting more appliances to DR programs could unlock savings for homeowners while helping utilities balance the grid’s needs.
