Nine alternators(two more not in pic) at 1.8 Megawatts EACH, prime power rated. The plant is designed to run seven paralleled for a total of 12,600,000 watts, or 12.6 megawatts. Each is driven by a 3516B V16 Caterpillar, that sucks a ton of fuel, and costs a small fortune to maintain. Each generator burns about 100 gallons of fuel an hour at full load, and takes over 100 gallons of oil(which is changed every TEN DAYS). Here's whats happens when one has a bad day. That's only one side. It also shelled two pistons out the opposite side. Pistons measure ~ 7" in diameter. They make one heck of an ashtray.
