Peak Demand Limiting – Every day, all summer long

  • Utilize Building Automation System (BAS) to set air conditioning temperature to 76 degrees except for rooms/areas that must be maintained cooler.
  • Set rooms that are not utilized during the summer to unoccupied mode. Use manual controls for areas not on BAS. Unoccupied mode reduces air flow and controls temperature to 80 degrees. (Consider relocating offices and classes to increase the number of unoccupied rooms.)
  • Reduce common-area lighting to emergency lighting levels in Dolan Science Center and Library where safety is not compromised. Library lights can be controlled by the staff as needed.

Demand Response Event Plan

When:

  • For participation in program to reduce electric load during periods when electric demand on the grid exceeds generation – to minimize brown outs and black outs.
  • We will receive notification 30 minutes before events start, and we usually get notice of possible event the day before the event.
  • Events are typically called between May 1 and October 31 and can last up to 10 hours.

Plan:

  • Implement Peak Load Limiting Plan, if not in effect.
  • Start and transfer load to specified emergency generators. This will cause a momentary (less than one second) interruption to equipment on emergency circuits when transferring the load to the generators and when transferring the load to utility power in all buildings, except Rodman, Administration, Administration Annex, and Dolan Hall, which do not have emergency generator power.
    • Note: UPS’s have been installed in the ITS closets to maintain connectivity to JCU classroom servers.
  • Shutdown air conditioning in Bernet, Millor, Murphy, and Don Shula Stadium.
  • Evaluate AC in Rodman, Administration, Administration Annex, O’Malley, Library, and RecPlex on a case-by-case basis.
  • We can restore air conditioning during events based on temperature and/or humidity limits, depending on duration of the event.
  • Turn off Stadium lights.

Peak Load Contribution Plan (PLC)

When:

  • Calculated by PJM Grid operator using the maximum load used during a specified one or two hour(s) window on five days with the highest load on the electric grid. This is used to determine capacity charges applied to all electricity used for next year.
  • PJM may project more than five days, but probably less than eight – there were only five days identified in 2014 and 2015.

Plan:

  • Implement Peak Load Limiting Plan, if not in effect.
  • Shutdown all air conditioning except approved exceptions.
  • Turn off Stadium lights.
  • Manually reduce ventilation in Varsity Gym, Intramural Gym, and Dining Hall.
  • Turn off domestic hot water pumps for all buildings.
  • Turn off refrigerators and other electrical convenience appliances during PLC period.
