Google doesn't help me, but my wife often tells me that our area (along the coast of Suruga bay in Shizuoka prefecture) has the most annual sunshine in all of Japan (I won't argue with her ;-) ). Definitely the number of solar installations here is dramatically rising. Practically every day I see a new one. 5 years ago it was wind turbines (it's also insanely windy here most of the time...) Shizuoka is home to a very…
50000 kilowatt, for how many milliseconds? The phone in my pocket has a 500 _giga_watt battery. What a pity it's only 700mAh...
I know you probably already realise this, but they obviously mean kWh. I normally wouldn't comment, but to most people a kW is a kWh and, in context, it's obvious they're talking about kWh.
It's inexcusable for journalists reporting on any energy issue.
You just can't give any slack on this point. It's 100% wrong to say one thing and mean the other thing.

3-Gigawatt turbines for 10-hours == roughly 30 Gigawatt-hours of storage potential. IIRC, the project only cost $1.6 Billion in 70s money, so after some inflation... it's still a pretty cheap storage mechanism.

They should put solar panels on wind turbines then :)
That's 600 MWh for 257 million USD. Tesla's powerwall has 10 KWh for 3500 USD. Interestingly, that's about the same price point. Efficiency-wise, the centralized Japanese solution makes probably more sense for large centralized solar plants, whereas Tesla's model probably makes more sense for self-owned solar panels.

Grid storage that stabilizes a grid is much more valuable than storage of power to shift production to non-peak times.

I believe distributed generation is the future.
It obviously requires the right kind of terrain etc, but it is very very cool.

Which Tesla model? There are 2: the Powerwall for home use, and the Powerpack, for businesses. The Powerpack starts at 100kWh, and goes as big as you have money for. Initial reservations are mainly for the Powerpack. https://en.wikipedia.org/wiki/Tesla_Powerwall Grid storage that stabilizes a grid is much more valuable than storage of power to shift production to non-peak times.
