POSCO E&C said on the 19th it will launch an "energy-saving challenge" for residents of The Sharp to help overcome the national energy crisis and begin a participatory energy-saving campaign focused on multiunit housing.
The challenge was prepared to respond to the deepening instability in energy supply caused by the prolonged war in the Middle East and to spread energy saving as a daily practice.
POSCO E&C will introduce "Energy Rest," a public participatory demand management program operated by Korea Power Exchange, to The Sharp apartment complexes and, based on this, run a "100-day energy-saving challenge" for residents.
"Energy Rest" is a program in which, when Korea Power Exchange issues "Public DR" (demand response) due to unstable power supply, participants reduce electricity use for a set period (one hour) and receive rewards based on their reduction performance.
POSCO E&C, in collaboration with Korea Power Exchange, enabled residents to easily participate in "Energy Rest" by receiving "Public DR" alerts through The Sharp smart home system. The service is currently provided to about 20,000 households across 30 complexes nationwide, including Seoul, Gyeonggi, Incheon, and Daegu.
In fact, the highest individual reduction per session is 2.9 kWh (about 2,900 won in rewards), and residents who participate actively are saving an average of about 500 Wh per session. Based on 23 Public DR events in the first quarter of 2026, cumulative rewards of about 11,500 won per household are expected.
The challenge will run from Apr. 20 to July 28, and an awards ceremony will be held to mark Energy Day (Aug. 22) to recognize households with excellent savings performance.
A POSCO E&C official said, "The energy-saving challenge is a lifestyle-focused campaign that produces results through voluntary participation by residents," adding, "We will continue to expand smart home-based energy management services to provide tangible benefits that residents can feel while contributing to society's energy-saving efforts."
