On construction sites, big power loads are needed for big equipment. Often much of this power comes from diesel generators. Diesel is a highly polluting fossil fuel, spills can occur, and diesel generators can be very noisy. AMPD Energy has designed a continuously operating battery storage system that is safe for the rough and tumble of construction sites, 30% less noisy and of course produces no diesel particulates and 85% less CO2. Most importantly they are able to deliver the high-power loads needed, for example, to run massive equipment like cranes.
