"The total transmission capacity between the two grids is 1.2 GW"
That's a tiny amount for an industrialised nation of 125 million people, considering that the border between the grids cuts right between Tokyo and the other western centres of population.
I think this, and the nuclear power shutdown, lend some context to Japan’s push for a hydrogen economy.
- tlamponi 6y agoThat's only the inter-grid exchange capability, over AC1 <-> DC <-> AC2 transformation, not the total one If you read the article, the US has about the same inter-grid exchange capability for the west and east coast grids. Japan has alone over 50 GW of solarpower, and that's only a small share of their energy mix. They produced 1009 TWh in 2015, that'd be an average of 117.95 GW, and usage is seldom average, but with daily peaks. I'd take an educated guess and say their nets can handle multiple hundreds of GW to up to a TW just fine..
