How it works

From load list to switch-on

01

Size it

Run your site through the free power calculator, or send us your load list. We size the Enertainer, P-Grid or generator set to what you actually draw, not a guess.

02

We install and commission

Delivered, connected and commissioned by our team, with distribution boards, cabling and changeover covered.

03

Scale as the build moves

Swap up or down as the programme changes, from groundworks peak loads to fit-out. Hire flexibility, or buy and redeploy across your sites.
