A project at AGC’s float glass plant in Seingbouse, France, has helped decarbonise the manufacturing process.

The partnership with energy company E.ON. included the installation of a 1.3 megawatts (MW) Organic Rankine Cycle (ORC) plant where residual heat is recovered to generate CO2-neutral electricity.

A photovoltaic power plant was installed across 27,000 m² of the factory’s premises, generating clean, renewable electricity from the sun.

A first PV plant of 2.7 MWc was installed in 2024, followed by the installation of a second PV plant of 5,1 MWc which has been operational since the beginning of 2026.

Together, these systems provide the Seingbouse facility with approximately 15 gigawatt hours (GWh) of decarbonised electricity annually —a substantial portion of the site's needs.

This prevents around 900 tons of CO2 emissions each year.

The project is structured as a long-term Power Purchase Agreement (PPA), where E.ON financed, built, and operates the facilities, selling the power back to AGC at a fixed price.

This model provides energy security, shields AGC from volatile market prices, and required no initial investment from AGC.

The project is also supported by the French government as part of the "France Relance" plan, operated by ADEME.

This initiative builds on a successful partnership with E.ON that began in 2019 and which included various joint energy efficiency projects in Europe, such as the project in Hungary and on multiple sites in the Czech Republic.
