Chubu Electric Power (TYO:9502) plans to introduce revised standard rate plans for extra-high and high-voltage customers effective April 1, 2026, according to its Tokyo bourse filing on Thursday.

The key change is an update to the fuel cost adjustment system, which will now more appropriately reflect trends in both fuel prices and wholesale electricity market prices.

Concurrently, the unit electricity usage charge will be adjusted to ensure the total cost for customers remains approximately the same as it was in December.

The company stated these revisions are designed to streamline management while maintaining a reliable electricity supply.
