The following submission statement was provided by /u/redingerforcongress:
> Named Crimson Storage, the site holds 350 MW / 1400 MWh of standalone battery energy storage, delivering flexible power to California’s grid.
> The project is held by a fund managed by Axium (80%) and Recurrent Energy (20%).
> During construction, the project employed about 140 union workers, including International Brotherhood of Electrical Workers, International Union of Operating Engineers, Laborer’s International Union of North America, and the International Association of Bridge, Structural, Ornamental and Reinforcing Iron Workers Union.
> Upon activation, Crimson Storage became the largest active single-phase storage project in the world, and second-largest energy storage project currently in operation of any configuration. The project holds two long-term contracts with utilities Southern California Edison and Pacific Gas and Electric. Both contracts are part of reliability mandates made by the California Public Utilities Commission (CPUC).

I assume the title doesn’t mean single phase as apposed to 3 phase?

>Most residential homes operate on single-phase. The solar industry has made it very easy to install solar and battery backup for these single-phase services. What if you have a three-phase service? Is it possible to have single-phase backup paired with three-phase solar?

No it doesn’t seem like it means single phase in electrical terms. I idea why you are taking about domestic supplies this is a grid scale application

definitely does.
> Residential homes will usually use a single-phase power supply or inverter, while commercial or industrial facilities will use three-phase supplies.
They are the same thing. There are AC/DC converters.
>In recent years, there are different kinds of AC/DC converter topologies used in the V2G system, including single-stage single-phase and three-phase, two-stage single-phase and three-phase, ZVS inverter, and so on. Reference presents an electrical vehicle charger that used a single-phase interleaved AC/DC boost converter. In, a high-performance single-phase bridgeless interleaved PFC converter is proposed. Both have the same function, which can reduce the battery charge and discharge current ripple, however, neither of them could work with wide output voltage.

A seeking alpha article on the site says "largest (...) to reach operation in a single phase" so it seems it just means constructed all at once as opposed to dividing up the project into multiple stages / "construction phases", which is common for large energy infrastructure projects since you can usually build it partially and start operating while you finish the rest.

I agree with you here. The article isn’t clear on what it means by that but it would be crazy if they built this as a single phase AC electrical system. If that were true they should be more clear about it and explain why/how.
Also look at the sets of three power lines coming away from it in the first picture. And transmission lines in the background.

I think phase here means built in one investment decision. So they committed to 350MW in one go as opposed to 100MW, then 200MW then 200 MW.
Would definitely be 3 phase power, since basically all AC power distribution is 3 phase.

How does it, there is no way you would connect this sort of power on a single phase, that part of the grid would be completely unbalanced. I don’t think you know why you are talking about and just linking stuff with the same buzz words

Yep that’s what I was thinking, clearly an author who doesn’t even understand the basics of the subject
Koakie t1_isx6s1f wrote
I also would have guessed that.
Then the article throws this monkey wrench into it
>Upon activation, Crimson Storage became the largest active single-phase storage project in the world, and second-largest energy storage project currently in operation of any configuration
It doesnt make any sense. Probably it means the battery is one DC battery unit which converts to 3 phase AC, instead of 3 battery units, one for each phase. Idk.

Texas should be taking notes here, as they've murdered residents by their incompetence by not hooking to the national power grid.

three phase is only in commercial, not residential.
