Also Houston/CenterPoint.
Our install was done June 23-24, and we received PTO last night (Sept 1) -- so almost exactly 10 weeks. I should have called CenterPoint to check on status and see what the issue was, but never did, partly because just enough updates trickled out to reset my "if I don't hear anything by..." clock. Here's the timeline we had:
- June 23-24: Install
- June 25: Passed inspection
- July 1: Received the distributed generation application from CenterPoint that I needed to sign. Rant: Tesla never mentioned anything about this -- I would have expected their local install team to at least mention to keep an eye out for it...
- July 2: Signed/Submitted the DG application (digital sig...)
- July 19: Notification from CenterPoint that the application was rejected (2 areas where labels were not consistent on the one-line design). Tesla resubmitted a couple minutes later (I'm guessing CenterPoint had been in contact with Tesla, and someone just updated the workflow when the correction came in...).
- Aug 4: Local Tesla team calls to ask if they can stop by and swap in the correct breakers into the gateway and take some additional pictures for CenterPoint. The band of breaker that matches our panel wasn't avail at install. Something tells me the CenterPoint asked why 2 of the breakers didn't match (I'm not happy -- mixing breaker brands is a potential electrical code violation).
- Aug 9: Received an email from the Tesla project advisor asking if we were planning to use the co-branded Tesla/MP2 net metering plan (we're not)...
- Aug 5: Notifications (about 3 in total) from CenterPoint that the application was approved and moving to the utility's inspection process.
- Aug 27: Notification from CenterPoint that the application was moved from rejected to re-submitted (I did not get a notification it was rejected a 2nd time, so this one is odd...)
- Sept 1: Get a text message from Tesla saying the application with our utility had been submitted (seems this was ~2 months late?). Checked email and saw a flurry of notifications from CenterPoint saying 1) the system was reviewed and design approved, 2) utility inspection was in progress, 3) inspection passed, 4) an email with the link to digitally sign the interconnection agreement, and 5) an email from Tesla saying the same thing as the text message. About 90 min later, I was able to read/sign the interconnection agreement. CenterPoint did their signature 10-15 min later, and we received PTO. The Tesla project advisor even sent an email letting me know that I needed to sign the interconnection agreement, but that came in a min or two after I had already signed it...
- Sept 2: Tesla updated their site to reflect PTO (text/email notifications...)
Now I just need to get Tesla back out here to install the corner trim pieces -- they were on backorder at install. At least the project advisor confirmed that it is a punch list item open on our account...
