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 noon6 p.m. * 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
