Published: Oct 02, 2026 11:32 (GMT+8)
ORIX has started construction of the Yufu and Yonezawa grid-scale battery projects in Japan, sized at 70 MW/280 MWh and 75 MW/309 MWh respectively, for a combined 145 MW/589 MWh. The plants are scheduled to enter operation in 2028 and 2030 and mark ORIX’s first large-scale storage developments funded with external investors, with ORIX holding 23.7% and three outside investors collectively owning 76.3%. The structure indicates that Japan’s utility-scale storage market is broadening from balance-sheet investment toward professional asset management and diversified institutional ownership.

[SMM PV Flash] US Energy Permitting Reform Bill Sparks Mixed Reactions from Clean Energy Sector
A bipartisan bill aimed at expediting the permitting process for energy projects was recently introduced in the US Senate. The bill proposes to accelerate authorization and environmental reviews for energy projects and transmission lines. While this initiative is expected to significantly ease backlogs in interconnection queues, certain compromise provisions have raised concerns across the clean energy sector. The final implementation of this reform will directly impact the deployment pace of mid-to-long-term solar PV and energy storage systems across the US.
