Enerbank Supports Renewable Energy Procurement for Public Facilities in Sakado City, Saitama Prefecture

Enerbank Inc. (Representative Director: Jugo Sato; Headquarters: Chuo-ku, Tokyo; hereinafter: Enerbank) has supported Sakado City, Saitama Prefecture (Mayor: Kiyoshi Ishikawa) in selecting a retail electricity provider for the transition of power used in public facilities to 100% renewable energy. Sakado City will utilize the electricity reverse auction service 'Eneoku' provided by Enerbank to switch the power supply for the Sakado City West Cleaning Center to effectively 100% renewable energy starting in April 2026. Enerbank and Sakado City will continue to strengthen their partnership to promote the decarbonization of public facilities within Sakado City using 'Eneoku'. - Support Content for Sakado City (1) Preparation and organization of specifications (draft) and usage data, etc., related to renewable energy power procurement (Free of charge) (2) Implementation of the reverse auction (Free of charge) Sakado City Official Website Announcement: https://www.city.sakado.lg.jp/soshiki/20/57284.html - Results of Electricity Procurement Support 1. Auction Results (1) FY2026 Electricity Cost (Planned): 60 million yen (2) Standard Electricity Cost: 68.7 million yen *Planned price calculated based on TEPCO's standard menu (3) Reduction Amount: Approximately 8.7 million yen (4) Reduction Rate: Approximately 12.70% 2. Greenhouse Gas Emission Reduction via Renewable Energy Introduction 1,291 t-CO2 (Calculated based on TEPCO standard menu emission factor of 0.000421 t-CO2/kWh) Unlike standard bidding where one company submits one bid, the use of a reverse auction allowed retail electricity providers to bid multiple times, successfully extracting a contract for a more affordable renewable energy plan. - Comments from the Department in Charge [Sakado City West Cleaning Center] In Sakado City, electricity procurement tasks through traditional bidding processes had become difficult due to the complexity of rate structures following the surge in electricity prices. However, by conducting this reverse auction, we received 14 bids from a total of 6 companies, allowing us to realize not only the transition to renewable energy but also cost reductions. When considering how to proceed with the introduction of Eneoku, the concrete support from Enerbank was extremely easy to understand. Outsourcing part of the procurement work—which was previously the duty of municipal staff—such as calculating planned prices and preparing specifications, alongside the reverse auction service, also led to operational efficiency. - Future Developments While renewable energy power tends to be costlier than conventional power, utilizing the electricity reverse auction 'Eneoku,' which allows for re-bidding while viewing other companies' bid prices, makes it possible for operators to procure renewable energy power at a reasonable price. Amidst the rising difficulty of electricity procurement operations as electricity rate structures become more complex due to the soaring power market, we will support efficient electricity procurement by utilizing Enerbank's digital solutions. We will continue to strengthen our collaboration with municipalities nationwide, supporting initiatives aimed at realizing 'Zero Carbon Cities' through the use of 'Eneoku' and 'Green Tickets.' - Support Service Site for Zero Carbon City Realization for Municipalities: https://www.enerbank.co.jp/zero-carbon-city - For inquiries regarding this matter, please contact us via the following windows: - Local Government Officials: https://form.run/@RE-guide1 - Retail Electricity Providers: https://form.run/@RE-guide2 - Private Businesses considering the introduction of renewable energy: https://form.run/@RE-guide3 [Company Overview] Company Name: Enerbank Inc.
