• Strategic plan to reduce energy consumption by 20 percent at all seven of its production sites and cut its carbon emissions in half by 2030. 
• Up with energy efficiency, down with costs. 
• A need for company-wide transparency, data quality, standardization, and reporting.

For this initial large-scale collaborative project, Siemens offered an impressive overall solution that included everything from consulting to implementation of software and hardware from the field level to the management level.   The centerpiece of this cross-factory process and energy optimization in production is the Simatic Energy Manager PRO energy management system.   The services provided by the Siemens team include the engineering, supply, installation, and commissioning of the electrical and non-electrical metering points and connection to Simatic Energy Manager PRO. For example, water metering: Siemens selected Sitrans FS clamp-on ultrasonic flow meters with non-intrusive sensors that could be installed during operation without having to cut the pipe. Another example is the vortex flow meters: Siemens chose Sitrans FX330 flow meters due to their extremely high accuracy and extremely low pressure losses.

For over 200 years, the Stoelzle Glass Group has been manufacturing high-end glass containers for the pharmaceutical, perfumery and cosmetics, spirits, and food and beverage industries. Its Medical and Laboratory Department completes the company’s offering with comprehensive laboratory consumables, instruments, closures, and small quantities. The company is based in Köflach, Austria. In 2021, some 3,200 employees generated a turnover of €416.5 million. In addition to nine Europe-wide production and decoration sites, Stoelzle Glass USA became Stoelzle’s first American production site in March of 2021.

Since the project was launched in early 2021, all seven factories have been taking steps to connect to the energy management system, with the Köflach site leading the way. By the end of 2022, all the other European factories will be connected via the company-wide WAN, and the U.S. location, which has been part of the company since March of 2021, will follow in 2023.
