With locations worldwide, Biogen Idec uses cutting edge science to discover, develop, and market biological products for the treatment of serious diseases with a focus on neurological disorders. They are the world’s oldest independent biotechnology company and a Fortune 500 company with more than $4 billion in revenues.
The Cambridge campus is the largest site within Biogen Idec and consists of 750,000Ft2 of space consisting of biologics manufacturing facilities, laboratories, process development, datacenter and office space with over 2,000 employees.
In 2007 Biogen Idec completed the installation and commissioning of a combined heat and power plant in the lower basement of Bldg 6A to provide a stable and very efficient source of heat and power for the Cambridge Campus. Since initial start-up, the plant has undergone numerous efficiency upgrades to maximize the efficiency of the plant and return on investment. The plant is operated in a corporate partnership with Dalkia Energy Services (Veolia Energy).
The state of the art facility is the recipient of the Cambridge GoGreen Award and has a model for many successive successful CHP implementations. A series of upgrades over the past two years has maximized the ROI of the plant. In 2010, the plant saved Biogen Idec $3.97M in energy costs.
The Biogen Idec Cogeneration plant is rated for 5.3MW of electrical output and up to 100,000 PPH of steam output at 150 PSIG. The heart of the plant is a Solar Taurus 60 Combustion Gas Turbine
rated for 5.3MW and equipped with a heat recovery steam generator (HRSG) and supplemental duct burners. The CT/HRSG produces 25,000 PPH of steam (unfired) and up to 52,000 PPH of steam with supplemental duct firing. The system is equipped with a selective
catalytic reduction treatment unit using anhydrous ammonia injection for NOx and CO control. The CT generator operates in parallel with the NSTAR electric utility and is equipped with load shedding RussElectric Switchgear for island operation during a utility failure. Providing back-up steam and peak steaming capacity are two Nebraska Steam Boilers each capable of 50,000 PPH. The plant also maintains an automated connection to the district steam system to provide a third level of back up for the steam supply.
To provide a uniform steam load the plant feeds two double effect steam absorption chillers for production of chilled water. These chillers include a 600-ton baseloading machine and a 1,200-ton prime load machine. The plant has undergone a series of efficiency upgrades and capacity additions over the past few years including:
· Installation of the 600-ton baseloading absorption chiller
· Retrofits of all plant feedwater and condensate pumps with VFDs for capacity control and energy reduction
· Installation of water reclaim systems to capture and reuse high purity wastewater and air conditioning condensate
· Allen Bradley Factory Talk to allow for remote visualization and control of all plant accessories from the control room
· Installation of a VFD air compressor with integrated zero-loss air dryer and heat recovery
