New biomass heating plant advances climate neutrality at Roche Penzberg site

February 2026


After 18 months of construction, Roche has inaugurated a new biomass heating plant at the Penzberg site. Using residual forest wood for energy generation, this facility marks a significant milestone in Roche's roadmap toward CO2 neutrality.

Impact on Roche CustomBiotech

Roche in Penzberg serves as the global headquarters for Roche CustomBiotech, with the majority of the CustomBiotech portfolio produced on-site. Consequently, infrastructure advancements at this location directly benefit our partners: by lowering the carbon footprint of our production processes, we actively support our customers in reducing their own Scope 3 emissions and achieving their supply chain sustainability targets.

Roche investment in sustainable energy supply

Roche invested approximately 22 million euros in this northern extension project. The facility is designed to secure a sustainable energy supply while significantly reducing environmental impact.

  • CO2 reduction: The plant will save approximately 7,800 metric tons of CO2 annually.
  • Site impact: This equates to a reduction of roughly 18% of the site's annual greenhouse gas emissions.
  • Global goals: This project supports the Roche Group’s target to reach zero greenhouse gas emissions (Scope 1 and 2) by 2050.

Critical process steam for biotech production

Successfully commissioned in early 2026, the plant is now fully operational and serves as a primary source of process steam, which is essential for the biopharmaceutical manufacturing workflows used for CustomBiotech products.

The 5.6-megawatt facility generates approximately 7.6 metric tons of steam per hour. This thermal energy is actively utilized for:

  • Sterilization: Cleaning fermenters and bioreactors.

  • Purification: Producing high-purity water (WFI).

  • Stabilization: Supporting various inactivation processes.

Technical Dimensions: The structure measures 25 meters (82 ft) in width and height, and 35 meters (115 ft) in length, featuring a 47-meter (154 ft) chimney. The current energy output is sufficient to supply the equivalent of 380 average detached homes (at 15 kW each).

Circular economy and regional resources 

The facility prioritizes a balanced resource cycle. The wood fuel consists of residual forest wood sourced from regional forestry operations within a 100-kilometer (62-mile) radius, minimizing transport emissions.

The system is designed for maximum efficiency. Waste heat is fed into low-temperature and district heating networks, allowing the site to utilize nearly all thermal energy generated by the fuel.

Additional sustainability features

  • Solar Power: A rooftop photovoltaic system with 156 modules generates ~70 kilowatt-peak (kWp) output.

  • Self-Sufficiency: From spring 2026, the electricity generated will fully cover the new building’s internal power consumption.

  • The heating plant is a prime example of how we combine state-of-the-art production with maximum resource efficiency. This allows us to reliably manufacture medicines and diagnostics for patients worldwide as well as critical raw materials for our partners.
