Intertie (1969)

- “Intertie” showcases the construction of the Pacific Northwest-Pacific Southwest Direct Current Intertie, a high-voltage electric superhighway between the Northwest and Southwest that helps balance power needs in the West and allows the two regions to share surplus electricity. It was the largest single transmission program ever undertaken in the United States. Construction began in the 1960s through a cooperative effort between public and private utilities in the Pacific Northwest and California. The 3,100-megawatt combined AC and DC transmission system was completed in 1970.
Made by documentary filmmaker Robert Charlton, the 1969 film includes aerial photography and ambient sound, as well as a terrific bluegrass score by Northwest musicians Ron Brentano and Mike Russo. It also includes a fascinating time-lapse sequence of the building of the Celilo Converter Station, the northern terminus of the intertie in The Dalles, Ore.
BPA entered “Intertie” into film festivals all over the world. It won eight awards, including the coveted Diploma of Excellence at the Venice International Film Festival and the Golden Eagle at the Council on International Non-Theatrical Events. The digital transfer was made from a 1990s video master, which retains the true colors of the original.
In 2016, BPA upgraded the BPA-owned portion of the transmission line, which runs 265 miles from The Dalles, Ore., to the Nevada/Oregon border.

The instrumental montage at the end is stunning! Incredibly well made film and score.
Definitely, dnb303... absolutely beautiful. I play 5-string banjo too, both bluegrass style and claw-hammer style, and I got tears of joy in my eyes listening to that rendition at the end. All the background music was totally awesome, no doubt, and those guys building up those towers by the seat of their pants practically definitely had some awesome fortitude. :-)
@@TerryMcKean The music is from two 60's musicians of which are named Mike Russo (the guitarist) and Ron Brentano (the banjo frailer), more of their stuff is on youtube. Cheers!
@@thatpickingguy Right on.... thanks Jerimiah
23:46 was a great prediction. When the line was completed, it had a capacity of 1,440 megawatts, running at just over 400,000 volts. The wires were large enough and the insulators long enough to where they could raise the voltage in the future if it was ever needed. They could use the same transmission line but upgrade the equipment on either to send more power through it.
In 1984 the line was boosted to 1600 MW
1986: Upgraded to 500kV and 2000 MW
1989: 3100MW
2016: 3200MW 560kV
Designers did a damn good job future proofing the line. Sure, a lot of insulators, conductors and towers have been replaced over the years, but I imagine much of it is still original.
Good idea to future proof something this big but I am sure it also made the upfront cost higher.
As a control operator at Diablo Canyon Power Plant it was an honor and a privilege to send generation into this system. The pay wasn't half bad either!
In 1996 two major failures occurred. July 2-3 over 2 million people lost power due to over heating lines. August 10 was extremely hot causing a cascading failure of the inter-tie. I remember my area of California being without power for about 12 hours. Some 4 million were without power.
1:37! I want that stove! LOL I have long wanted one of those old fashioned wood-fired stoves. Can cook anytime, don't have to worry about electricity or gas, and as a bonus you keep the house warm. :)
Thank you for this video. I drive my truck past your dam and past Sylmar
@16:13 is a brilliant piece of comedy writing
That's my father at 9:43 He was stern man, cruel even He sure did love electricity.
No line like this one anywhere in this world hahahahahaha
NOT THE CALIFORNIA OF TODAY...
Not the California of 4 years ago.
I was about to say it’s absurd to complain that things change over 50+ years, but then again, in 1969 hardly anybody had access to a caps lock key, so maybe the world was better off after all.

I hope no terrorists find out how easy it is to blow up towers of such a long power line! Would like to know how such an extreme hi power DC to AC transverter might work!
thermistors, basically big transistors for high power.
Back when this system was built, it would have used mercury arc rectifiers at the source (AC->DC) end and motor generators at the destination (DC->AC) end. The next generation ones used transistor inverters and the current generation typically uses IGBTs.
@@tristenturner832 Thermistors are resistors that have a known resistance change relative to their temperature.
The rectifiers (AC>DC) have a duel purpose. In addition to converting the AC, they also control which direction the power flows in the line. The rectifiers work similar to a lamp dimmer control. When the line voltage is set lower at one end, the power will flow in that direction. The amount of power sent over the line can be controlled by the difference in voltage at the two ends.
Also, back in the mid 80's, the rectifiers used SCR stacks.
@@tristenturner832 Thyristors, thermisters are different.
The power goes oneway south. That needs to stop.
Back before the days of sissies, OSHA and lawsuits. Before men turned into the metrosexuals of today. What a difference from the 1960's - 2000+.
*FUN FACT:* Silicon Valley's kombucha-quaffing man-buns and woe-men owe their lives of leisure and ease to hardscrabble get-'er-done men like these.
The power goes oneway south. That needs to stop.
