The problem is it does not exist. The extended text with the video (published earlier this month) states:

"Tesla’s 52 MWh Tesla Powerpack and 13 MW solar farm will store solar energy produced during the day and deliver it to the grid during the evening hours to reduce the amount of fossil fuels needed to meet energy demand. This dispatchable solar project ..................."

So, no change to my opening post. Six months on it appears that no project has been completed, otherwise they would be putting out videos about it, rather than proposed schemes.

That's sad. but it DOES look Like a TESLA commercial. When it happens, and it will, it will probably be a lot more mundane. TECO has just built a 23 megawatt solar facility on 106 acres near me. While it wasn't a secret, few people knew about it until suddenly, there it was. I don't doubt that eventually they'll have their own batteries too. It's all a matter of money.

...and thanks for that. Very pleased to see a project up and running.

That list includes (No.6) the project you linked to at #19 and which, acording to Tesla's own comments for the video on 8 March, is not yet built. 

I am suspicious of this company's PR. Perhaps unreasonably, but when things do not ring true I become suspicious. Either these projects are completed, or they are not. 

Can anyone confirm that the plant in S. California is completed and running? The link you gave says it has not been officially launched (January) but was brought on line in December. Has it yet been launched? 

I do not like being negative about something which obviously has enormous potential, when used in connection with solar panels, but surely, given Tesla's usual approach of fanfaring achievements, it would have produced solid info that something that big was definitely producing.

I hope my suspicions are unfounded and these things are actually being successfully completed.

Tesla’s Australian Battery Shows It Can Also Make Huge Profits

https://futurism.com/teslas-australian-battery-shows-can-make-huge-profits/

IN BRIEF
The 100MW battery Tesla built in South Australia is proving to be profitable for its owner, Neoen, earning the company an estimated $800,000 over the course of just two days. This profitability may convince other countries to invest in future Tesla battery systems.

Tesla Solar Roof customer gives insights on cost and installation process
https://www.teslarati.com/tesla-solar-roof-installation-cost-insights/

Excerpt:

According to Huynh, he immediately signed up for the Solar Roof in the Textured finish as soon as they became available, considering his house needed a new roof and he was on the market for a solar system. Huynh further noted that Tesla first reached out to him about a year later, stating that they wanted to do a site survey. The site survey involved two people from Tesla analyzing the details of his roof, including its orientation to the sun, and determining the best system for it. According to Huynh, Tesla also deployed a drone to survey the surrounding area.

The installation involved a surprising 20 people who worked on the Solar Roof for two weeks. Part of the reason why it took so long to get the system installed was due to bad weather. Huynh noted that Tesla is probably still optimizing the ideal number of people it needs to deploy when installing its photovoltaic glass roof tiles.

According to the Solar Roof customer, the difference in price between the photovoltaic system and a traditional roof is substantial. Thus, he does not recommend the tiles for those who are financially-sensitive.

I would expect a "substantial" difference in cost between the photovoltaic roof and a "traditional" roof, but that's comparing apples to ducks.

My question is how does it compare with a "traditional" roof fitted with "traditional" PV panels?
