Enehub Charts of the Week
Kyushu’s day-ahead power price for October 16, 2025, delivery jumped to the second-highest level this year and the fourth-highest since mid-February 2023. The spike comes as Sendai Nuclear Power Plant’s Unit 1 prepares for a periodic inspection starting tomorrow, Genkai 4’s restart is delayed by a fault discovered during maintenance, and temperatures across parts of the region continue hovering around 30°C. The area’s premium to the system price reached +21%, the second-highest since mid-2021.
Global tech companies are among the most active offtakers in Japan’s corporate PPA market. While Meta and Apple have yet to disclose any deals, Amazon, Microsoft, and Google have announced over 400 MW of combined planned and operational capacity. Amazon leads with the largest and most diversified portfolio, which includes the only wind project among the three.
As of last fiscal year, more than 300 municipalities and prefectures in Japan had implemented ordinances regulating renewable development through measures such as consensus-building requirements and zoning rules. The increase reflects local opposition to solar and wind projects and the shift away from the FIT/FIP scheme, which also means the loss of a centralized asset registry.
