Plans in place for upgrading main electrical transformer

The Department of Construction and Architectural Services has scheduled work to upgrade the main campus electrical transformer in preparation for increased power needs for the new hospital and our growing campus.

The work is scheduled for:

• A one-hour period on Friday, Nov. 16, from 10–11 p.m.

• The 5-day period of Wednesday, Nov. 21, at 10 p.m. through Monday, Nov. 26, at 5 p.m.

The work will require temporarily disconnecting from Southern California Edison and supplying full power from the co-generation turbine engines at Loma Linda University Health’s Central Utility Plant. 

No impact to normal power is expected, as the co-generators are fully able to sustain to the campus. However, due to shutting off the feed from Southern California Edison, there is an increased risk of unexpected loss of normal power.

The bulk of the work has thus been specifically scheduled for the Thanksgiving holiday weekend, when energy demand for the campus will be reduced. 

Proactively, the proton accelerator will be shut down to further reduce power demands. 

Further contingency planning lays out the following procedures in the event of co-generation failure:

• Four backup generators will be on site to provide power. Priority fuel delivery has been coordinated for these generators. 

• Power for the Medical Center and Children’s Hospital will take priority during this time. Should the backup generators fail, emergency power will take over. 

• Backup generators will also be in place for several of university buildings. 

The work has been coordinated in advance with the appropriate departments, including Medical Center Facilities Management, LLU Campus Engineering, Medical Center Construction, the Proton Treatment & Research Center, and administration.
