NTEP #4 Cooling Tower is available for use...High Speed Fan only. New contacts ordered for Low Speed.
Demand Response (DR) Event #1 is in effect today starting at 1600-1800 today.
*NOTE: Per Client request, we will adjust CHW Out Temperatures to 42°F one hour before the official ‘start’ of the event!
Logbook entries and actions for both STEP and NTEP, please.
1500 - Commence DR Event #___ from xxxx - xxxx. Placed "CHW OUT" Temp to 42.0°F on Chiller ____ and ____ (operating Chillers)
At 1800, we will start slowly lowering CHW OUT Temperatures. This prevents any issues on campus by causing a huge surge all at once. DO NOT want to change/switch/secure any chillers during an event UNLESS IT IS AN EMERGENCY. Campus Operations will also be making adjustments, which will have further power and temperature affects throughout the campus.
Both Plants can now return to normal operating temperature in 0.5-degree increments. When changing CHW Out setpoint: NTEP = at operating chiller OptiView panels; STEP = from Desigo.
1800 - Secure from DR Event #1. Placed "CHW OUT" Temp to 41.5°F on Chiller ____ and ____ (operating Chillers at BOTH PLANTS)
1830 - Placed "CHW OUT" Temp to 41.0°F on Chiller ____ and ____ (operating Chillers at BOTH PLANTS)
1900 - Placed "CHW OUT" Temp to 40.5°F on Chiller ____ and ____ (operating Chillers at BOTH PLANTS)
1930 - Placed "CHW OUT" Temp to 40.0°F on Chiller ____ and ____ (operating Chillers at BOTH PLANTS)
2000 - Placed "CHW OUT" Temp to 39.5°F on Chiller ____ and ____ (operating Chillers at BOTH PLANTS)
2100 - Placed "CHW OUT" Temp to 39.0°F on Chiller ____ and ____ (operating Chillers at BOTH PLANTS).
Resume normal chiller plant operations for both NTEP and STEP (operating efficiently at both locations)
