Installing agricultural solar power generation equipment (off-site)
Toyo Kohan has concluded an off-site PPA *1 agreement with Chugoku Electric Power Co., Inc. (hereinafter "Chugoku Electric Power") and is proceeding with the installation of agricultural solar power generation equipment. Chugoku Electric Power, in cooperation with Ecostyle Co., Ltd. and Sainosakaki Co., Ltd., will develop a new agricultural solar power plant with a total capacity of 64 MW and supply the generated electricity and environmental value to the Kudamatsu Plant. This off-site PPA utilizing agricultural solar power generation *2 is the first of its kind in the Chugoku region. The Kudamatsu Plant plans to replace approximately 20% of its electricity consumption with green power with additionality *3 by fiscal year 2030, which is expected to reduce GHG emissions by approximately 25,000 tons per year. This initiative is also expected to contribute to the revitalization of local agriculture by reclaiming abandoned farmland and improving agricultural management.
- Off-site PPA (Power Purchase Agreement): A power purchase agreement in which a power generation company installs solar power generation facilities in a location away from the power demand facility, and a retail electricity company supplies renewable energy electricity to specific consumers over the long term via the power grid.
- This is a method of balancing agriculture and power generation by installing solar power generation equipment in the space above farmland. This makes it possible to reclaim abandoned farmland, improve agricultural management, reduce carbon dioxide emissions from agricultural crop cultivation, and contribute to expanding the use of renewable energy.
- This refers to the effect of expanding the amount of renewable energy introduced by installing new solar power generation facilities, rather than using existing renewable energy facilities.
Introducing a virtual PPA utilizing wind power generation.
In March 2026, Toyo Kohan signed a contract with HSE to introduce renewable energy using onshore wind power. This agreement utilizes the FIP system *1 aimed at promoting renewable energy and adopts a virtual PPA *2, one of the mechanisms for procuring environmental value.
Specifically, HSE will supply approximately 18 GWh of annual environmental value generated from three domestic wind power plants operated by the HSE Group to Toyo Kohan as an aggregator *3. As a result, greenhouse gas (GHG) emissions from Toyo Kohan 's business activities are expected to be reduced by approximately 8,700 tons per year. This initiative is not only the first case of renewable energy introduction derived from wind power generation within our group, but also the first case of implementing a virtual PPA.
Toyo Kohan is engaged in energy-saving and energy creation activities aimed at realizing a decarbonized society, based on our group's medium- to long-term environmental goal "Eco Action Plan 2030," aiming to reduce GHG emissions (Scope 1 and 2) by 50% by fiscal 2030 (compared to fiscal 2019) and achieve carbon neutrality by fiscal 2050. As for energy creation activities, we are promoting the introduction of on-site and off-site solar power generation, and together with this initiative, we plan to replace approximately 25% of the electricity used at the Kudamatsu Plant with renewable energy by fiscal 2030.
- This is an abbreviation for the "Feed-in Premium" system. It is a system that provides a certain amount of premium (subsidy) to power generators for electricity sold at market price.
- A Power Purchase Agreement (PUT) is a contract that virtually purchases only the "environmental value" of renewable energy, without actually exchanging electricity.
- A business that aggregates the electricity and environmental value created by renewable energy power generators, controls the supply and demand balance, and maximizes the use of energy resources (power generation facilities, energy storage facilities, etc.) to supply electricity to the electricity trading market, electricity retailers, and consumers.

Heat source conversion and new technologies
Japan's first large-scale glass melting furnace using an oxygen combustion method begins full-scale operation.
TOYO GLASS began full-scale operation of a large glass melting furnace using oxygen combustion at its Chiba Plant in March 2026. This is the first time in Japan that oxygen combustion has been introduced to a large glass melting kiln for glass bottles, with a daily production capacity exceeding 200 tons.
Conventional glass bottle manufacturing required a large amount of energy for melting raw materials at high temperatures, which was a major factor in GHG emissions. The oxygen combustion method introduced this time uses high concentrations of oxygen instead of air, achieving nitrogen-expelling combustion and improving heat transfer efficiency to the glass. As a result, it is now possible to reduce GHG emissions per melting furnace by about 20% while maintaining the same production volume as before. Additionally, by adopting this method, there is no longer a need for a large regenerative storage chamber using bricks for heat storage, contributing to "decarbonization" of the manufacturing process through optimized energy efficiency and "resource conservation" through streamlining equipment.
