Q.ENEST Begins Supplying Corporate PPA and Renewable Energy to Adient LLC

Q.ENEST Denki Co., Ltd. (Headquarters: Minato-ku, Tokyo; Representative Director: Yusuke Hoshino; hereinafter, "the Company"), a subsidiary of Q.ENEST Holdings Co., Ltd. (Headquarters: Minato-ku, Tokyo; Representative Director: Hee Jae Chang), and Q.ENEST Power LLC have commenced providing renewable energy through a corporate PPA (offsite physical method) and high-voltage power to two bases in the Kanto area operated by Adient LLC (Headquarters: Yokohama City, Kanagawa Prefecture; hereinafter, "Adient"), the Japanese base of Adient, a global supplier of automotive seats, starting April 1, 2026.

This initiative delivers renewable energy generated at five existing solar power plants owned by Q.ENEST Power to Adient's two Kanto region bases via the power grid. It simultaneously supports Adient's decarbonization and stabilizes electricity costs through a hybrid configuration that combines renewable energy with high-voltage power tailored to the operating characteristics of each base.

・Target Bases: Adient LLC Headquarters (Yokohama City, Kanagawa Prefecture), Oppama Plant (Yokosuka City, Kanagawa Prefecture)

・Power Plants: 5 solar power plants owned by Q.ENEST Power LLC

・Supply Method: Hybrid configuration of Offsite Corporate PPA + High-voltage power

・Estimated Annual Power Generation: Approximately 523,000 kWh

・Annual CO2 Reduction: 1,149.35 t-CO2 (of which 219.79 t-CO2 is reduced by PPA)

Background

In the domestic automotive industry, there is a growing movement towards decarbonization across the entire supply chain. Adient, a supplier of automotive seats, is required to reduce CO2 emissions from electricity procurement and prepare for future cost increases at its domestic bases.

This initiative was realized against this background, as part of Adient's concrete efforts to advance the decarbonization of electricity procurement at its domestic bases.

Hybrid Supply of Corporate PPA × High-Voltage Power

Renewable energy will be supplied from five existing solar power plants owned by Q.ENEST Power LLC to Adient's two Kanto region bases via the power grid.

At Adient LLC Headquarters and Technical Center, teams for automotive seat design, prototyping, and testing develop high-performance seats. At the Oppama Plant, multiple manufacturing processes, including seat assembly and foam molding, operate primarily during the day, causing significant fluctuations in electricity demand throughout the day. Therefore, a hybrid configuration is adopted, where corporate PPA power (from existing solar power plants) covers concentrated daytime operating hours, and high-voltage power supplements during off-hours or demand fluctuations.

By utilizing non-FIT non-fossil certificates, the environmental value belongs to Adient. This initiative is expected to reduce annual CO2 emissions at Adient's two Kanto region bases by 1,149.35 t-CO2, and can be utilized for Scope 2 emission reductions and compliance with international environmental initiatives such as RE100.

About Q.ENEST's Corporate PPA Model

While general PPAs typically involve long-term contracts of 20 years or more, Q.ENEST's corporate PPA achieves a "short-term, fixed-price model" on an annual basis by utilizing group-owned solar power plants.

We believe that Adient adopted this model because it allows them to gradually advance decarbonization while controlling costs with a fixed price, considering future business changes such as factory relocation or expansion.

The Company supports customers in achieving both decarbonization management and business continuity by supplying renewable energy tailored to their business characteristics. Moving forward, we will continue to contribute to the realization of a sustainable society by providing energy solutions tailored to the demand characteristics of corporate customers, including those in the manufacturing industry.
