2. Ice Energy was Created to Solve The Peak Electrical Demand Problem
Peak Demand:
Drives higher cost of energy
Uses the most polluting energy
Creates need to build new peak power plants (growth of peak at 3-5 times base)
Primary cause of rolling blackouts & equipment failure
Data/IT centers are large users of energy
Typical Summer Day Utility Load Profile
Other Commercial, Residential, and Industrial
Commercial Lighting
Commercial A/C
Residential A/C
A/C is the Root Cause
~40% of demand

In the state of California there are approximately 10M air conditioners on light commercial and residential buildings (20% light commercial, 80% residential)
Each year approximately 500,000 new units of this same type are sold
About 50,000 air conditioning units can be found in Anaheim, with about 4800 new units of this type sold every year
The impact of air conditioners on the state of CA and Anaheim
Power consumption
Emissions
Peak demand = higher greenhouse gas/climate impact, grid problems, drives construction of new power plants (peakers)
Requires utilities to first look at reducing demand rather than build new power plants
AB2021 put in place, requiring peak demand to be reduced by 1% per year
Last Fall, new category created by the CPUC and funding put in place, Permanent Load Shifting (PLS) to encourage shifting of load (particularly air conditioning) from peak to off peak
Firms demand for wind energy
50 MWs creates 50,000 gigawatt hours of peak
Reduces CO2 by 40%, NOx by 55%

3. The Hotter it is, the Bigger the Problem A/C Efficiency Drops as Temperature Increases

6. Typical Data or Communications Center Application
Combines data center air conditioning with patented Ice Bear® energy storage technology, using each when most efficient
Off-peak hours: Conventional equipment provides cooling
On-peak hours: Ice Bear® unit provides cooling using only 300 watts
Return Air
Data Aire compressor locked-out
for 6 hours during on-peak
300 watts pumps refrigerant
to RTU evaporator coil
Ice Bear uses Data Aire’s Auxiliary Water Evaporator Coil
