The Inner Harbor Project consisted of the installation of heating, cooling, and power generation plant equipment to provide high temperature hot water and chilled water for the entire 3 million square feet of multi-use space in several buildings at the Harbor East mixed-use development project.

​

The plant uses high efficiency centrifugal chillers and natural gas-fired boilers and includes a 2 MW natural gas turbine generator for peak shaving and a 1 MW diesel powered generator for life safety power for the facility. The natural gas turbine generator is used for peak shaving and is operated in parallel with the utility. Heat from the generator exhaust and generator cooling system is utilized to pre-heat heating water utilized for space heating and domestic hot water heating in the Baltimore Marriott Waterfront and Courtyard Baltimore Downtown / Inner Harbor hotel buildings.
