Hybrid Cooling for Data Centers The Ice Bear® Randy Zwetzig Vice President of Market Development

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 during peak Source: California Energy Commission 6 a.m. 12 noon 6 p.m. 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% * Estimates for light commercial and residential cooling in California from ARI & CEC data

The Hotter it is, the Bigger the Problem A/C Efficiency Drops as Temperature Increases Source: Pacific Gas and Electric Company Time Dependent Valuation (TDV) – Economics Methodology

The Ice Energy Hybrid Cooling™ Solution Transforming air conditioning to be: less costly more efficient more reliable green By using less expensive, less polluting, nighttime power to create & store cooling for use the next day
