Proposition G, a $247-million bond measure approved by voters of the East County region in June 2006, is funding the project, budgeted at $26.32 million in construction costs. As proposed in the hospital's Facilities Master Site Plan, Prop. G is funding several other infrastructure construction improvements at the publicly owned hospital, which opened in 1955.

McCarthy is also in the process of building the new $46-million Central Energy Plant at Grossmont Hospital, construction costs for which are also being financed by Prop. G. The three-story, 18,400-square-foot energy plant will include electrical switchgear, emergency generators, cooling towers, chillers, fuel tanks, medical gas tanks and various mechanical equipment that will help meet future capacity needs of the hospital. The plant also will include a control and locker room for facilities management personnel.

The new energy plant additionally will contain a new state-of-the-art cogeneration combustion turbine generator. The cogeneration equipment is not part of the bond-related construction but will complement the efficiencies of the Central Energy Plant and help save millions of dollars in energy costs while reducing the hospital's emission of greenhouse gas pollutants by 90%.

Construction of the Central Energy Plant began last September, and is scheduled for completion in March of 2015. In late April of this year, approximately120 concrete trucks delivered the more than 1,120 cubic yards of concrete needed to construct the foundation for the plant.
