The main goals of this project were three-fold; renew and increase the capacity of the utilities that serve the hospital; reduce utility costs; and make Lancaster General Hospital a “Light on the Hill” in the event of a regional catastrophe. The original central plant was built in the 1950s and had to remain operational throughout construction. The project required significant coordination to minimize impact to hospital operations and because of the site’s physical limitations, as the only way to build was up.

The project consisted of upgrading the existing boiler plant with a new 800 HP boiler and feedwater system. The heart of the system is a new 3.5 MW combustion turbine CHP system, expandable to 4.5 MW for future growth. Other major components include:

  • A new high-pressure gas line across Lancaster City to provide firm gas and correct the balancing of the local distribution company
  • A chilled water plant upgrade that renewed cooling towers, adding a 1,000-ton steam turbine chiller, a 1,000-ton plate and frame exchanger
  • A new emergency power system of 4.0 MW, expandable to 8.0 MW, with emergency paralleling switchgear, substations throughout the hospital, fuel storage, and fuel pumping system
  • An electrical system that allows the hospital to operate as an island.
  • Coordination, communication and teamwork were the keys to the successful completion of this project.
