Power supply is rather generic.

What I am implying here, is Silverado need not have to place an order for a long lead time gas/steam powered turbin. A portable diesel generator (or 2 or 3) on a rental basis could probably get them going.

I was involved in these products thru a joint venture when working for Eaton Electrical, formerly Westinghouse/Cutler-Hammer, with Enercon http://www.enercon-eng.com/ and we used Cummins Diesel Engines on some of the Federal Prison projects. In this case they were used for back up power only.

Onin, Cummins http://www.cumminspower.com/en/products/generators/diesel/mins , Solar Turbin, there are many out there...

These portable units built on flab beds offer flexibility, moving them from site to site and on a rental basis, less cash outlay.

I'm sure "The Boyz" at Silverado have this covered.

Just my 2 cents.
