Sakura City Optimizes Power Procurement with Eneoku, Achieving 100% Renewable Energy

Enerbank Inc. has supported Sakura City, Chiba Prefecture, in selecting retail electricity providers to transition its public facilities to 100% renewable energy. Utilizing Enerbank's power reverse auction service 'Eneoku', Sakura City has effectively switched the electricity of 54 facilities, including the city hall and schools, to 100% renewable energy starting April 2026. This marks the first initiative of its kind in Chiba Prefecture.

The reverse auction method allowed multiple bidding from retail electricity providers, successfully securing a cheaper renewable energy plan compared to traditional single-bid systems. As a result, the city achieved an estimated 20% cost reduction, saving approximately 60 million yen compared to standard electricity rates. Furthermore, the introduction of renewable energy is expected to reduce greenhouse gas emissions by approximately 3,500t-CO2.

Sakura City officials noted that 'Eneoku' and Enerbank's comprehensive support significantly reduced the burden of power procurement tasks, simultaneously achieving decarbonization and cost reduction. Enerbank will continue collaborating with municipalities nationwide to support zero-carbon cities.
