The business of demand response has undergone numerous changes. 

Two decades ago, a demand response "offering" might have been a favorable rate to encourage an industrial customer to switch off equipment during emergency peaks. More recently, it's the use of remote controls to change and aggregate capacity for commercial, industrial or residential customers during those peak times.

Today, the definition of demand response is changing once again. It’s starting to encompass all kinds of behind-the-meter resources like batteries, solar PV, HVAC, smart lighting systems, industrial equipment, refrigeration and smart water heaters -- many of which are being mixed and matched to serve different grid needs.

As a result, demand response is more than just about cutting load during peak times. It’s about providing minute-by-minute and second-by-second services to balance grid voltage, regulate frequency and shift clean energy consumption to different times of the day. Welcome to the world of aggregated DERs.

Elta Kolo, a grid edge analyst with GTM Research, joins the show to help us explore this complex and newly emerging world. We talk about some of her recent research on aggregated DERs.
