Generator size calculator

Power rentals for oil and gas, refineries, construction, manufacturing and events need quick fixing. The site should not experience downtime.  

Choosing the correct generator size is key here. Why? A smaller generator size runs the risk of failure, while a bigger size means wasted cost and fuel.  

Calculating the generator size is the quickest way to make the right choice. This way your site never loses power, and you have a reliable estimate to begin with.  

While an online calculator is a good starting point, it’s always better to talk to the experts at Aggreko, as with our knowledge we’ll get the most efficient setup.

Choosing the right generator size delivers far more than just power, it drives efficiency, cost savings, and sustainability. Here’s why rightsizing is a smart investment for your project:  

1. Lower operating costs: Reduced fuel consumption and fewer maintenance cycles.  
2. Maximum efficiency: Generators operate within their optimal load range.  
3. Reduced energy consumption: Power supply matches demand, eliminating inefficiencies.  
4. Minimal environmental impact: Efficient fuel use leads to fewer emissions.
