Berkshire Sterile Manufacturing (BSM), a Massachusetts-based sterile filling contract development and manufacturing organization (CDMO), will install solar panels by end of Q2 2023 to offset 20% of the company’s energy consumption.

BSM’s 120,000 square foot fill finish and development site in Lee, MA houses several cleanrooms, laboratories, office spaces, an onsite daycare, and a warehouse.

In Q1 2023, the company installed a new roof with a new TPO membrane and improved insulation to reduce energy waste and prepare for the installation of nearly 1,500 solar panels. BSM is purchasing the panels from Dynamic Energy and working with Eversource to gain interconnection approval by demonstrating that the grid and existing infrastructure can support the new panels.

“Replacing the roof was the most involved part of this project,” said associate director of engineering, Ron Trefzger, “now that’s complete, we are just waiting for approval from Eversource to install the panels.”

BSM’s day-to-day operations involve significant energy consumption to maintain cleanrooms, operate sterilization equipment and isolators for drug manufacturing, and to keep the lights and heat on for the 112 hours the plant is open each week.

The planned installation will include nearly 1,500 panels which are expected to produce around 500,000 kWh of electricity per year. For Berkshire Sterile, this will offset 20% of the company’s expected energy spend.
