Veolia Energy North America has purchased the Portland District Cooling Company from Marubeni Sustainable Energy, making Portland Veolia’s first district energy system in the Pacific Northwest.

The company says it owns and operates the largest portfolio of heating, cooling and cogeneration networks in North America, with systems across the country in Atlanta, Baltimore, Boston, Cambridge, Grand Rapids, Kansas City, Las Vegas, Los Angeles, Oklahoma City, Philadelphia, St. Louis, Trenton and Tulsa. As part of this acquisition, Veolia Energy plans to implement its best practices for preventive maintenance, and will continue to invest in the system to increase efficiency.

The Portland district cooling system produces and distributes chilled water to the Brewery Blocks, a five-block shopping and professional district in Portland’s post-industrial Pearl District neighbourhood. The plant, with 4,000 tonnes of installed chilled water capacity, houses two centrifugal chillers along with a state-of-the-art automation system that operates the chillers and controls system devices. Customers who currently utilize chilled water from the system include retail businesses, office buildings, luxury apartments and condos, a large datacenter and a performance art hall.

The district cooling system was initially developed by Portland General Electric (PGE), a local electric utility that constructed the district plant and an underground distribution loop from 1999-2001.
