At one time I maintained a 50 kW (100 kW circular polarization) FM
that had a 50 kW generator. The Transmitter Power Output was about
22.5 to 25 kW (I just don't recall the exact number) and we ran a
closed HVAC system, with two AC units to cool the transmitter. This
put the total load just under 50 kW of three phase 208 Volt power.
We had a 50 kW diesel stand-by rated motor-alternator.
We had a huge power outage for two weeks. The power co-op and the
station communicated hourly. I spoke with them every few hours. I
expressed my concern that if we lose the generator, they loose the
only radio station that covered their footprint. I was very concerned
about fuel. I could not get the fuel companies to deliver because the
roads were so unsafe, not to mention our long driveway.
I went to several Wal-Marts and bought a bunch of five gallon fuel
cans. I bought road taxed fuel and kept it running for two weeks.
The co-op said they had trailers with 250 to 500 gallon fuel tanks on
them and they could bring one out if we got to be in a real bind.
Unlike the fuel trucks, the trailers don't have long hoses, so we
would have had to cut the fence.
The co-op called the announcer who put on the air that everyone was
back up. I walked into the studio and the remote control told me
I phoned them and they were embarrassed. They got us back up in a
However, and this is the point of my story, the road taxed fuel, and
the maintenance visit for a stand-by unit that ran too long, cost less
than half what power normally cost from the co-op for two weeks.
