February 17, 2026 Nippon Electric Glass Co., Ltd.
– Achieving an Annual CO₂ Reduction of Approximately 500 Tons -
Nippon Electric Glass Co., Ltd. (Head Office: Otsu, Shiga, Japan; President: Akira Kishimoto; “NEG”) has newly installed a solar power generation facility at an off-site location for its Shiga-Takatsuki Plant (Nagahama, Shiga) and commenced operation on February 1, 2026. The electricity generated will be supplied to the Shiga-Takatsuki Plant utilizing Japan’s self-wheeling system*.
The facility is expected to generate approximately 1,200 MWh of electricity annually, equivalent to the electricity consumption of around 300 households. This initiative is projected to reduce CO₂ emissions by approximately 500 tons per year.
*The self-wheeling system is a mechanism that allows businesses owning power generation or storage facilities to transmit electricity they generate or discharge to their own sites (such as factories or business locations) via the transmission and distribution networks operated and maintained by general power transmission and distribution utilities.
- Background and Future Initiatives
NEG aims to achieve carbon neutrality by 2050 and is working to reduce CO₂ emissions at its sites both in Japan and overseas.
The Shiga-Takatsuki Plant has been operating an on-site solar power generation system on a full scale since April 2023. The newly introduced facility is part of NEG’s efforts to further expand the
use of renewable energy by utilizing electricity generated off-site and delivered to the plant by utilizing the self-wheeling system.
NEG will continue to promote the use of renewable energy as part of its sustainability initiatives.
