Meridian138° is an independent data infrastructure provider for Japan's energy transition.
The name refers to east longitude 138°, the line along which Japan's 50 Hz and 60 Hz grids meet, and where Japan's grid connectivity challenges concentrate.
We publish benchmarks, signals, and analyses that surface where storage and grid opportunities are emerging. Our methodology is public; our data is transparent; our goal is to make the market context legible for investors, developers, and operators.
