Excerpts from Steve Lamb letter referencing high school generator.

This is the 275kw generator that we installed at the Local High School. At first they were looking at Natural Gas and the consulting firm told them they would need at least a 400 KW and about $400,000.00 to do the project. We went in and did a load survey and looked at a load of about 230 KW maximum over winter summer timeline and at time of startup 2 weeks ago, we were at 150 KW.

We went in and explained the situation with gaseous fueled engines of the size for the 400 KW and even with the 275 KW, a gaseous fueled engine against a comparable diesel would be cost prohibitive.
The other factors we pointed out were that with NG fueled engines, should they ever have a disaster, the fuel supply would most likely be cut off and would negate their standby unit.

We discussed what, if any, their long term expansion plans were for the School and with the new addition which is about 10 years old. There are no plans to expand this facility for the foreseeable future.

On a positive note, the age of the new addition with the VFDS installed on the remodel we found that when they have an event as voltage outage/switching, it takes about 15 minutes for the air handlers to come up to full power, thus giving us built in load shedding; a big plus for a Standby system.

With the information we had we decided to see if we could make the 275 KW program fit within their budget. This allowed us a 17 to 20% reserve which would allow for some minor expansion/components. The configuration we came up with would allow us to inter connect the 1600 amp switch in line with the main breaker and the ASCO Series 300 worked great. We interconnected using EXANE 2000 Volt Locomotive cable. With its flexibility and ruggedness, it allowed us to use mechanical composite hydraulic clamps for the wire runs in the ducts and etc. On the transfer switch; for testing we connected the terminals 8 & 9 and enabled the perimeter circuit so the school load could be used to load the generator without worrying about if something should happen to the generator the switch would automatically go back to normal.

On the fuel system we were able to work with the fire marshal and were able to use a 1000 gallon double walled fire rated fuel tank. We interconnected the fuel tank with Teflon steel braided hoses. The fuel tank has a Krueger Sentry Gauge that will tie into the low fuel alarm on the generator system.

In the control room we mounted the remote annunciator and it is powered by a small KVA transformer mounted outside in the transfer switch and also powers the battery charger. The unit’s block heater is powered off of the 480 volt system in the transfer switch.

Final costs to school were in the $85,000.00 range!
By the way, the 275kw unit above has a MTU engine on it!!!
As we know the future will be about being the one who comes up with an idea where we can sell product that is what the customer needs, not what everyone else sells.

Thank You and Have a Nice Day!
