Hybrid battery + diesel systems sized for tower crane peak loads. Rent a generator half the size you'd otherwise need. Cut fuel costs. Stop oversizing for surges that happen 10% of the time.
Tower cranes draw heavy peak power during lift cycles — typically 200–400 kW for a few seconds at a time. Between lifts, the load drops to nearly zero. To handle the peak, contractors traditionally rent a generator sized for the peak — 250 kW, 400 kW, or larger. That generator then runs at 5–15% load most of the time, which is the worst possible operating condition.
Add a battery to the system. The battery handles the lift peaks. The generator only sees the smooth average load — which is much smaller. You can rent a 100 kW or 125 kW generator instead of a 250 kW one. It runs at 60–80% load (its efficient sweet spot), uses far less fuel, lasts longer, and costs less to rent.
