Powering a Marquee

When powering a marquee, it’s essential to consider what will be inside the marquee and what power will be required. As you mentioned, it’s better to calculate the total power consumption first before choosing the right generator. Here’s a breakdown of what to consider:

1. Total Power Requirement
Calculate Wattage and kVA: List every device, light, or appliance that will be used inside the marquee, including lighting, sound systems, fans, or any other equipment. Add up the total wattage (or kVA) required.
Add a Buffer: After calculating the basic requirements, add a little extra capacity for unforeseen devices or extra power draw from appliances that may be plugged in during the event. A general rule is to add 10-20% extra to your estimate.
2. Catering Equipment Power
Electric vs Gas Equipment: Catering is often the largest power consumer in marquee events. Caterers may use a range of electric equipment like ovens, refrigerators, coffee machines, or heating lamps. It’s essential to get a list of the specific equipment they’ll use.
High-Power Appliances: Items like electric ovens, bain-maries, and hot water boilers can require significant power, and it’s crucial to ensure the generator can handle these high-draw appliances without causing power dips or failures.
3. Entertainment Power
Discos, DJs, and Bands: If your event has entertainment, like a disco or band, ensure you calculate the power needs for their equipment. This includes lighting rigs, sound systems, amplifiers, and even LED screens or projectors if used.
Backup for Sensitive Equipment: For entertainment, it’s also smart to ensure power is stable. Some sound or lighting systems may require uninterrupted power supply (UPS) to avoid issues during performances.
By carefully assessing each element in the marquee—whether it’s catering, lighting, or entertainment—you can ensure the correct power is provided, avoiding any outages or issues during the event.
