Thanks for the info.....was wondering about the transmission towers shown in several of your pictures.
We have our share of transmission towers around here too, Old Magnet. In addition to the usual AC lines, The Dalles is the northern terminus of the DC
intertie to the LA area. I spend most of my time trying to avoid the lines in my
shots...but did catch them in this one as i was shooting this refurbished Stearman at work. There are two separate lines seen here in the background.
The shorter one is an AC line that was built in the 1950's. The taller towers are
for the DC intertie line, AKA Path 65. They pull AC power off of the Bonniville
Grid and convert it to DC at the Celilo Converter Station just south of The Dalles
Dam. This line extends 846 miles to Sylmar, CA near LA where a similar converter
station changes the DC power back to AC for use on the AC grid in the LA area.The line has a capacity of 3100MW. The bulk of the power flows from
north to south during the summer when the demand peaks in California. (takes lots of air conditioning to keep all of those nuts cool) The line can
work both ways, and at times in the winter when demand peaks up here,
the energy flows south to north. The DC intertie was built in the late 60's.
The DC line passes through a ranch leased by SRS Ranches. You can see it
in the background of this shot. Just behind the combine and to the left of the frame is where they ground the northern terminus at what the BPA calls
Rice Flats ( yeah, I know....doesn't look very flat, but that's as close as your
are gonna get around here) .......details here if you need to know:
en.wikipedia.org/wiki/Pacific_DC_Intertie
A friend of mine was building a diversion terrace for the grower that owns
the site ( the grounding structure is buried out in his wheat field. He hit the
buried cable with his D7F. Not sure what it was, he called the BPA. They about had a stroke and told him to stay a LONG way away from it until they
had the intertie secured. ( he had been assured before he started that the
grounding loop was buried so deep that he wouldn't hit it....yeah sure.)
That episode turned out fine......nobody hurt. Didn't work out very good
for a spray pilot one spring day back in the '80's. He turned the wrong way,
flew right into one of the wires.........sawed the plane in two..
pilot KIA.
Here is one of the planes from Shearer Sprayers working along side the Intertie..........
........and he makes damn sure to turn away from the lines;
