What is Demand Response?
Demand Response (DR) rewards businesses for using less electricity during peak times. It’s a smarter way to support the grid: by adjusting demand instead of increasing supply. As Korea adds more renewables, grid stability becomes a challenge. DR helps solve this by turning flexible energy use into a marketable resource. With Enel X’s Virtual Power Plant (VPP), businesses can join the DR market through KPX and earn revenue, just by being flexible.
How does Demand Response work?
When the grid is stressed, operators can fire up costly power plants—or activate a DR network. Enel X aggregates flexible demand from businesses and dispatches it like a virtual generator. When called, participants reduce or shift usage briefly, helping balance the grid in real time. It’s fast, simple, and built around your operations. You stay in control, support the grid, and get paid.
