The Baltimore Convention Center signed Constellation, a unit of Exelon Corporation, as engineering, procurement and construction contractor to install water and energy conservation measures worth about $10m at its premises.

The installations are expected to be completed in 2013 and require no upfront spending from the Baltimore Convention Center. The convention center will save an estimated $18m over a 15-year term.

Commenting on the contract Baltimore Convention Center executive director Peggy Daidakis said that it will help the center meet its goals for reducing water and energy usage besides satisfying customers.

The convention center is expecting to save about 100m gallons of water and reduce 6,058 metric tons of carbon dioxide emissions annually over the next 15 years.

Baltimore City Department director of general services Theodore Atwood added, "The Convention Center project is another step in our efforts to reduce Baltimore City government’s electric power use by 20 percent by 2015."
