Ductless Heat Pumps & Demand Response
Ductless heat pumps represent one of the fastest-growing electrification segments, but unlocking their value as grid resources requires rethinking traditional demand response approaches. Unlike central systems, each mini-split offers smaller, distributed load—often just a fraction of a kilowatt—while also relying on proprietary, inverter-driven controls that limit integration with conventional thermostats. These systems don’t behave well…
