Yes, great pics, better than mine taken 5-26 which I did not post. Great that you were able to get your camera above the fence. I was disappointed to see that the cabling from the transformer pad in the foreground to the distribution cabinet behind it was not complete. Usually that is done before the transformer is delivered. Perhaps it is being done this week.
It could be some time (several weeks) before SCE gets around to bringing in the transformer, which they procure. I have monitored the construction of 3 SC, Rancho Cucamonga, Riverside, and Lake Elsinore, but I have never witnessed the transformer delivery. For this size, 2 MW, it probably takes a small crane because it is so heavy, but the installation and connection to the high distribution voltage (as much as 30 kV), probably takes only a day if the cabling is in place. Inspection and Tesla commissioning should take less than a day each. Two MW is a lot of power.
