To reduce down time when rig generators go down, we have skidded gen-sets mounted in car trailers that can be pulled to location accompanied with a mechanic or an electrician. All larger generators (100 kw - 230 kw) come with complete panels and can also come with a large power cord that can be hard wired into rig panel while existing generator is being repaired.
The light towers provide power and lighting. They are towable and also designed to fit in the box of any half ton.
