NSP / Xcel Energy

Nuts! The Rosefield 7200V delta sub is no more.

Dunno if anyone still visits this stream, but here's a pic of the Weber Ave. substation site as it is now.

A replacement transposition structure on the Lennox to Centerville line - one of the very last 69kV lines on the system with transpositions. The transpositions are among the very last poles on the line that still have crossarms, as almost all of the poles have been retrofitted with large armless posts like the other two. This line is old enough that the company is thinking about an eventual rebuild, and has already replaced the first segment out of Lennox.

The old transformer pole at Raymond still stands, along with its crossarm-mounted bank (I'd bet the three cans are GE units).

Looks like Xcel decided to add some better regulators to the 23.9kV circuit... wonder why there instead of inside the main fence?

Part of a weird structure added to reroute a line coming into the area. The lines going left all end in a downguy pole.

At least the 4160V system in Ihlen and 2400V delta system in Jasper (likely Home Electric Co. and not NSP) are still intact!

Not even the new stuff lasts forever. This is the last leg of that old 69kV line west of Sioux Falls. It seems that not that long ago, we had a storm come through that took out several of the poles - seems that this 69kV line is not that high a priority after all... (it runs from the 69/23.9kV sub east to an emergency backup tie to East River Electric Coop's 69kV system).

A few days ago, I passed the South Sioux substation well after sunset and I picked up on the fact there'd been a significant change, but what, I couldn't figure out. This is what I saw the next day - Xcel finally got around to taking down the long-abandoned lead-out for the old #3 4160V circuit (rebuilt in the late 1980s, along with the upper circuit on the next pole, which was originally 4160V circuit #2). The reason the pothead bushings look odd is that the terminals have insulating hoods taped over them. At least the old crossarm-style switch in the back survives - for the moment.

A recent picture of the South Sioux sub. Sure looks different without the 4160V wing and the shrubs that once stood along the fence.

Um, what?

The step-down now powering Hatfield. I really wish I'd hurried out that way when Justin told me of the old-style substation that once stood a few hundred yards south. I wonder though, did they have a muni lineman on the crew???

The branch line after the old Hatfield sub was replaced. The addition of the tap going to the right was what caused the old sub to be replaced...

Multiple risers at a solar farm powering part of the 23.9kV system. If it wasn't for this, the old Hatfield sub would still be humming away.

The 'Rosefield' 23.9kV / 7200V substation in the sunset of its life. It was replaced by a pole-mounted stepdown in 2021.

The biggest and smallest transformers I've seen so far on Xcel's 34.5kV system. A 500kVA 19.9kV/7970V step-down in front and a puny 0.5kVA can for a repeater on the dead-end pole.

The 23.9kV line coming into town and the step-down that has apparently long powered a 2400V circuit serving a portion of town.

An older pole trying to look like 4160V, but it is in fact 2400V.
