Gerresheimer site in Pfreimd with the new photovoltaic system installed on the roofs of the production buildings.
Gerresheimer, an innovative system and solution provider and a global partner for the pharma, biotech and cosmetic industries, has successfully commissioned a photovoltaic system at its Pfreimd site following a test phase. The system, located on the roofs of two production buildings, has an installed capacity of 500 kilowatts peak (kWp) and generates approximately 500,000 kilowatt hours (kWh) of electricity per year. With the new system, Gerresheimer is increasing the share of renewable energy in the site’s energy supply while simultaneously reducing annual CO₂e emissions by around 195 metric tons. By 2030, Gerresheimer aims to increase the share of electricity from renewable sources to 100% at all production sites worldwide and reduce its scope 1 and scope 2 CO₂e emissions by 52% compared to the base year 2019.
“Even though the solar power generated on our rooftops covers only a part of our total energy demand, it already makes our energy supply more independent, easier to plan, and future-proof—while also contributing to the gradual phase-out of fossil fuels,” explains Jochen Dörr, Global Head of Sustainability Management & Energy Technology at Gerresheimer Medical Systems. 
Solar Power from Own Roofs
The photovoltaic system installed on the roofs of the production buildings in Pfreimd will generate approximately 500,000 kilowatt hours of electricity annually. This corresponds to the average annual consumption of about 125 single-family homes. The solar power is used entirely on-site to supply the facility with energy, reducing dependence on external power sources and protecting the company from significant price fluctuations in the energy market.
The project was implemented through a Power Purchase Agreement (PPA) with a regional electrical engineering company, Hardy Barth GmbH. Under this model, Hardy Barth GmbH is responsible for financing, construction, operation, and maintenance. Gerresheimer purchases the generated electricity under a long-term contract with fixed terms. 
This model requires no initial investment for the company. At the same time, the model provides planning reliability for electricity costs and reduces technological and operational risks. At the end of the contract term, ownership of the photovoltaic system will transfer to Gerresheimer.
Rapid Implementation and Commissioning
Only around 12 months passed between the initial planning of the rooftop photovoltaic system and its successful commissioning. “The rapid implementation is the result of good cooperation,” says Birgit Heindl, Senior Plant Director Pfreimd, Gerresheimer Regensburg GmbH, Pfreimd, Germany. “We would like to thank everyone involved in the project who drove this initiative forward and successfully implemented it within a short period of time. This allows us to significantly increase the share of renewable energy in our power supply.”
At its Pfreimd site, Gerresheimer employs around 600 people to manufacture customized drug delivery systems, diagnostic and medical devices. These include, for example, applicators, auto-injectors, inhalers, laboratory disposables, prefillable polymer syringes, and components for on-body devices.
Gerresheimer publishes an annual sustainability report, which is available for download on the company’s website.
