I guess the Xcel contractor was here while I was out and about today, and installed a new smart meter.
Most of the purpose of this seems to be to give the utility more-granular use data, so they can charge more at peak time usage (or less for non-peak).
The old display was simple: flashed a number of kWh, so I could watch it get smaller over time.
The new one displays a bunch of different data. I couldn't figure any of it out, and couldn't find a guide to tell me what all this data represented. Called Xcel, and Vanessa walked me through all the numbers. Turns out to be mostly, a code number, then a total associated with that code.
For example, code 20 is net generated by my solar system. Up to 4 so far; seems about right.
Since my reading yesterday (old meter) was something like 81194, I'm expecting a bill for ~8800 kWh coming soon.
