Turbine Inlet Chilling (TIC) & Generation Storage (GS)
• Gas turbines only operate at 100% of their rated capacity when the temperature outside is 59F.

RECOVERED POWER
ADDITIONAL POWER
• By chilling below rated capacity and adding storage
TAS Generation Storage
95 100 90
• As temperatures climb into the 90’s and beyond, greater than 10% of the capacity of the turbine disappears.
RATED CAPACITY
all lost power is recovered, and additional power is
generated. • Storage and ancillary services including ramping benefits are captured as well

Turbine Inlet Chilling (TIC) Generation Storage Best Practices
DESIGNING THE SYSTEM
WHAT IS THE DRIVER FOR ADDITIONAL CAPACITY?
• Do you need the added capacity 24 hours per day
• How many hours do you want highest output
• What are revenue considerations – How valuable is another 5-7 MW on top of system addition
• Will there be an expansion effort onsite in future
• Availability of water

BEST PRACTICTES
WINTERIZATION
• No Glycol
• Drainable coils
• Not required on the TES Tank
© 2012 TAS Energy. All Rights Reserved. 34
COIL CONDENSATE
• Good quality
• Water makeup flexibility
SERIES COUNTERFLOW: EFFICIENCY

Lower Parasitic Loads
Higher CHW delta T = smaller TES tank, Pumps
BEST PRACTICTES
SUPER PEAK – 12/10/2 (charge, partial discharge, SuperPeak)
• Max benefit, lowest parasitics
• Larger Secondary Pump Skid, TES Tank flow rate
DESIGN CONDITION
• Design condition (95°F drybulb, 75°F wetbulb)
• 24 hour design DAY

BEST PRACTICTES
TES TANK
• AWWA Standard D-110, Type III
• Water Tight
• Thermal performance
• Concrete – lower life cycle cost, no painting
