Load control Proof of Concept project at a hospital in Suncheon, Korea

Company profile

Industry: Healthcare
Facility: 9-floor hospital
Energy profile: 300 AC units | 5 MW capacity
Air conditioning cost: USD 10,000 / month
Location: South Korea

The challenge

• Rising energy bills driven by inefficient operation of air conditioning systems
• Lack of visibility into real-time energy consumption patterns
• Limited insight into what distributed energy resource could support cost reduction or peak demand management
• No optimization of energy use across floors, zones, or different times of day
• No data-driven decision-making tools to guide efficiency improvements

The solution: xVPP Powersight

xVPP Powersight is an advanced energy data analysis platform that provides granular monitoring, trend and cost analysis, energy resource simulation, abnormal peak detection, and AI-powered insights and recommendations.

The analysis:

• AC setpoints and cooling performance
• Thermal comfort based cooling setpoint
• AC operation patterns per hospital floor, zone, and facility type (time of use and peak load timing and sizes)
• AC operation mode

The results

• Air conditioning energy usage is expected to decrease by about 9%, resulting in roughly 10% savings in air conditioning costs
• Expanding load management to additional buildings in the hospital complex could yield approximately 7% energy savings on monthly bills
• The overall monthly savings potential increases to up to 19% with maximum demand reduction
• In a simulated scenario that includes load management and the integration of solar PV and battery ESS resources, the hospital could achieve monthly savings of up to USD 20,000 (equivalent to approximately 15–20% of its total electricity bill).
