Achieving a Decarbonized Society in 2050

In a significant step toward realizing a decarbonized society by 2050, Enerbank Inc. is launching a collective purchasing initiative for renewable energy in collaboration with 33 municipalities in the Tokyo metropolitan area. Starting from May 11, 2025, the project will invite participants from businesses that will begin receiving power supply on April 1, 2027. Utilizing the reverse auction system known as 'EnerAuction', the project aims to secure renewable energy and non-fossil certificates efficiently, thus enabling participants to meet essential environmental regulations and global standards, including the SBT and RE100.

Overview of the Tokyo Area Renewable Energy Joint Purchasing Project

The initiative allows various businesses to pool their purchasing power, leading to significant cost savings compared to individual procurement. This year, the initiative has expanded to include Shibuya, Nakano, Sumida, Kiyose, Kasukabe, and Hadano, bringing the total number of collaborating municipalities to 33. The goal is to promote decarbonization and work towards achieving sustainability together.

Partnering Municipalities

The project encompasses municipalities within the Tokyo Electric Power Grid area. Even companies located outside the collaborating municipalities can join if their operations are within the grid's jurisdiction.

For more details, visit the project’s dedicated webpage: Enerbank Project Page. Several municipalities also offer incentives such as recognition as a renewable energy supplier or subsidy options for businesses participating in the initiative.

Project Achievements

In the renewable energy joint auction conducted in 2025, participating enterprises successfully adopted plans with a renewable energy ratio ranging from 30% to 100%. The average cost reduction achieved by switching to renewable energy was significant, with high-voltage users saving 16.0% and low-voltage users 9.7%. This balance between lower electricity expenses and increased renewable energy adoption showcases the project's effectiveness.

Note: The auction results from 2025 do not guarantee reductions for the fiscal year 2026.
