Clear answer
Clear answer, explained.
Lighting can be a significant contributor to a building’s total electrical load—especially in offices, retail spaces, and warehouses. By switching to LED lighting, which uses significantly less power than fluorescent or HID systems, the total load decreases. This reduction can lower the facility’s peak demand, particularly during times when lighting is fully in use alongside HVAC or equipment loads. When combined with lighting controls such as motion sensors and scheduling, LEDs can further reduce unnecessary usage and help prevent demand spikes.
Key points
What this means in practice.
- Reduces total electrical load from lighting
- Lowers peak demand (kW) recorded by the utility
- Helps reduce demand charge components on bills
- Additional savings with lighting controls
- Most effective in high-usage facilities
- Can complement solar and battery systems
When this applies
Best-fit environments.
- Commercial buildings with demand-based tariffs
- Offices, retail spaces, and warehouses
- Facilities with large lighting loads
- Buildings operating during peak demand periods
