Which Generators Power Commercial Real Estate Buildings?
Choosing the right generator size is key to ensuring tenant safety and building compliance. Based on industry standards and our sales data, here’s how generator sizes align with commercial real estate needs:
Small Commercial Buildings (20-200kW)
Ideal for small office buildings or retail spaces. A 100 kW Generac powers elevators and security systems.
Medium Commercial Buildings (200-600kW)
Suitable for mid-sized office complexes or strip malls. A 400 kW Caterpillar supports HVAC and lighting systems.
Large Commercial Buildings (600kW+)
Essential for high-rise buildings or large commercial complexes. A 1600 kW Kohler ensures tenant services and critical systems remain online.
