March 26, 2024
Seiko Group Corporation

Seiko Instruments Inc. (President: Takahiro Naito; head office: Chiba-shi, Chiba, Japan; hereinafter referred to as "Seiko Instruments"), a subsidiary of Seiko Group Corporation (Chairman & Group CEO, CCO: Shinji Hattori; head office: Chuo-ku, Tokyo, Japan; hereinafter referred to as "Seiko") that manufactures and sells electronic components, precision components, and other products, will switch the electricity purchased at its five manufacturing sites in Japan to contracts for electricity derived from renewable energy sources starting April 1, 2024, thereby achieving 100% renewable energy use at all manufacturing sites in Japan. This is expected to reduce CO2 emissions by approximately 18,000 tons per year.

The five units that will switch power contracts are Takatsuka Unit (Matsudo-shi, Chiba), Ohno Unit (Ichikawa-shi, Chiba), Sendai Unit (Sendai-shi, Miyagi), Akita Unit (Daisen-shi, Akita), and SII Crystal Technology Corporation (Tochigi-shi, Tochigi). Three of them (Takatsuka, Ohno, and SII Crystal Technology Co., Ltd.) will transition to electricity supply plans that combine non-fossil certificates designated as renewable energy, provided by TEPCO Energy Partner, Incorporated. The remaining two (Sendai and Akita) will shift to electricity supply plans utilizing environmental values derived from hydroelectric power plants in Tohoku and Niigata, provided by Tohoku Electric Power Co., Inc.

The Seiko Group has committed to achieving "Net Zero" greenhouse gas emissions from its business operations by 2050, striving to reduce its environmental footprint. Each of its operating companies is actively working towards this goal. In Japan, Seiko Group Corporation, Seiko Watch Corporation, and Wako Co., Ltd. have already achieved 100% of their electricity consumption from renewable energy sources. The entire Seiko Group, including Seiko Instruments Inc., aims to accomplish 100% renewable energy adoption in Japan by the end of FY2024.

The Seiko Group remains committed to energy conservation efforts and accelerating the reduction of CO2 emissions. This commitment involves promoting various measures, including transitioning to renewable energy power contracts, installing solar panels, and implementing on-site/off-site Power Purchase Agreements (PPAs). Through these initiatives, the Seiko Group aims to contribute significantly to the realization of a sustainable society.
