I had two powerwalls installed in July 2020. I've had solar panels for seven years so at the time the installation of the powerwalls was completed I was told that no ATO was needed. All that was needed was an inspection. That occurred and the system passed. After installation, the Tesla app works as expected showing the battery charging and discharging, providing power to the house. In fact, when we had a couple of power outages the PWs worked to provide power to the house. But, my utility bills didn't show any impact at all. I just shrugged and thought maybe it was just an aberration. But then I received a couple of emails from PEPCO, the electricity supplier, talking about the status of my application for an Energy Storage Only system. I thought this was a bureaucratic error so I ignored it. But then I decided to call Tesla and they told me that they did have to file an application with PEPCO of some sort and that it had been rejected. They are working to resolve this (five months later).
So it appears that while the app was showing me pretty illustrations of how the system is supposed to work, it wasn't doing anything to save money. Now i understand why my bills haven't gone down. This is crazy. Has anyone else experienced this kind of thing?
