the thing to invest in is batteries, after japan goes solar they will want to have electrical power also at night.

Thanks for that info. Looks like I had bought into an internet myth.

“Several HVDC links interconnect AC systems that are not running in synchronism with each other. For example the Nordel power system in Scandinavia is not synchronous with the UCTE grid in western continental Europe even though the nominal frequencies are the same. And the power system of eastern USA is not synchronous with that of western USA.

The reason for this is that it is sometimes difficult or impossible to connect two AC networks due to stability
reasons. In such cases HVDC is the only way to make an exchange of power between the two networks possible.

There are also HVDC links between networks with different nominal frequencies (50 and 60 Hz) in Japan and
South America.”

Looks like the Japanese installed a HVDC line (since replaced) in 1965.

The Japanese aren’t that crazy – there are several HVDC / freq converter stations linking the 2 grids, a couple of which have been in place for 40-50 yrs.

It is a little hard to see for sure in the graphic, but it looks like the big FIT has not had that much impact on the growth of residential. You could have expected that growth just from the prices dropping. It has mostly impact the big players, corp roof top and utility.

With the way things have been going after quake/wave I think it will be a long time before the Japanese people buy into the story that the atomic power company can be trusted.

I think the Japanese people are much more on board with solar than their government. And once the Japanese people as a unit decide to do something, they will do it. They are very socially cohesive and united in their mores.
I expect the Japanese people want to pull the profit rug right out from under the atomic polluters. Good.

They have a 50 Hertz and and a 60 Hertz grid, dividing technically the main island roughly from North to South into 2 grids.
There is no subsea cable to other Nations. With the promotion journeys of various politicians working for the Japanese atomic industry the rumor is spread

“If you build our atomic plants we might find funds to build a cable to Japan”
A colonial trick. The banks and investor funds have loughed about it.

Ah k, so they have the same regional monopoly deadlock we have.

Japan’s separate grids aren’t even connected to each other.

Is Japan’s electricity grid connected to any other countries for trade? The US has Canada and Mexico to trade with and the EU grid is very well connected as well.
