Yeah, I question that what was needed was actually done. I'll assume that you have a smart meter, and they just read some parameters remotely. Somewhere, I can't find it now, I saved off details that I found on the Landis+Gyr AXR-SD smart meter right after our neighborhood was all changed to smart meters some years ago.
Ours scrolls through numbers on its LCD, peak kW that I see in your printout is one of them, that is just the maximum ever recorded load from the house since meter installation or meter reset. Our meter quit sending out its signal earlier this year. I sure didn't know it did, but the scanning system detected it as no report for a long enough time, and a guy was sent out to swap out our meter. He programmed the then-present kWhr reading of the old meter into the new meter, and verified that it could be read remotely. I verified that both L1 and L2 were active (check that a 240v load works, like cooktop or pool pump motor) before he left. After he left, the peak kW peak detector reading was low, just the load on in the house at the moment. I checked back when I remembered a few days later, it was back up to the old peak load reading, as all A/Cs had run with pool pump, etc. to get peak demand back up there.
To do the load test that was done on mine, requires someone to come out with the load box (dummy load), and really load your service, to see how much voltage droop there is under a very heavy load. Just measuring voltage remotely isn't going to do that. They can't remotely load your service.
Just a note to others, many smart meters, mine included, have the ability to remotely disconnect service, and to set up a power-monitoring/power limiting scheme for people who don't pay their bills. The Landis+Gyr with a -SD model name suffix is for "Service Disconnect". A recalcitrant customer can be warned and then their power limited to just a light load, say like a refrig and a couple lights, customer uses anything more than that, the meter measures it, the scanning system see's it, sends the service disconnect command, and customer is without power. A few time of that I guess pokes the customer to paying their bill. If not, then meter is commanded to service disconnect, and until customer pays all the bills, or a big deposit and agrees to a monitored payment plan, no power for you! No need to send anyone out to the site.
