Description
Enehub 2-Hour Battery Spreads measure the arbitrage value available to 2-hour duration storage assets in Japan’s wholesale power market. They represent the daily revenue potential normalized to yen per MW, assuming perfect foresight of prices and 100% RTE, for a battery of a specified storage duration.
For example, the 2-hour Hokkaido spread on January 1, 2025, is calculated by subtracting the sum of the two lowest 30-minute prices from the two highest 30-minute prices, and then multiplying the result by 500 to normalize from 30-minute yen/kWh to yen/MW.
The indices are calculated daily at 5:00 a.m. Japan time.
The monthly view shows the average of daily spreads for each complete calendar month.
