Green energy projects at AGC
All the following projects help reducing our electricity consumption from the grid and the associated CO2 emissions. Many other projects are being studied to further increase our green energy production, with a continuous improvement approach.
The purchasing of green electricity (PPA)
In Belgium, AGC Glass Europe signed an electricity purchase agreement with Luminus for an annual supply of around 67 GWh of green electricity (14 wind turbines), increasing the share of renewable energy in the total energy consumption of its Belgian production facilities.
The installation of wind turbines at our sites
In Belgium, AGC partnered with Luminus for the construction of AGC's first on-site wind turbine in Seneffe in 2021. Luminus and AGC also intend to build one wind turbine on the AGC sites in Mol and in Zeebrugge.
The installation of PV panels on the roofs of offices and plants or on-site photovoltaic power plants
The first photovoltaic panels were installed at the Osterweddingen plant (Germany) and the Cuneo plant (Italy) in 2009 and 2010. Since then, other photovoltaic projects have been introduced at many other sites, amongst which large-scale PV panels at the Lodelinsart and Seneffe plants and the Technovation Center in Belgium. In July 2023, AGC and Helexia implemented one of the largest rooftop photovoltaic self-consumption plants in Spain at the Sagunto plant.
The most recently confirmed project concerns the installation of a photovoltaic power plant in partnership with energy company E.ON., at AGC's float plant in Seingbouse (France). Additional projects are under detailed study in Germany and Czech Republic.
The installation of heat recovery systems at our plants.
Heat recovery is the re-use of residual heat arising from a production process that would otherwise be lost, and which allows reduction of energy consumption. The heat recovery systems at AGC generate power by taking the residual heat of the flue gas from the glass melting furnace and converting it into electricity. This works either via an Organic Rankine Cycle (ORC) module that uses organic oil with a low boiling point or water as in a steam turbine generator.
Heat recovery systems were installed in AGC plants at Cuneo and Osterweddingen. A new ORC plant for residual heat recovery will also be installed at AGC ‘s float glass plant in Seingbouse (France), in partnership with energy company E.ON. In total, the heat recovery systems (ORC) produced 14,557 MWh.
The installation of a cogeneration plant (CHP)
Cogeneration, also called Combined Heat and Power (CHP), is a very efficient technology to generate electricity and heat at the same time, allowing an important reduction of CO2 emissions and others air pollutants. The AGC plant in Cuneo (Italy) has a 7MW cogeneration plant, which is managed by the third part company Wedge Power. While the electricity produced is consumed by AGC, the heat generated in the cogeneration process is supplied to a district heating system covering the city of Cuneo. The produced heat covers almost all the needs of the municipality’s heating network. Moustier is also supplied in electricity and heat by a cogeneration plant installed in 2022 by third party investor CORETEC.
