Introduction to Ice Energy!

• Company founded in 2003 - 15 years in business

• Headquartered in Santa Barbara California •  Distribution and Application center in Costa Mesa, CA •  R&D facility in Riverside, CA •  Manufacturing in Hammondsport New York

• Business experience with to utilities •  11 MWs installed to date •  41 MWs contracted and under construction •  Residential air conditioners

Ice Energy Mission !

Transforming Commercial and Residential Air Conditioning, the Principal Driver and Root

Cause of Utility Peak Demand, Into a Clean Flexible and Reliable Grid Resource for Utilities

and Consumers

Commercial Applications •  Ice Bears 30’s are combined with packaged HVAC •  The Ice coils are inserted into the packaged HVAC units •  1 Ice Bear can support multiple packaged units •  Paired with 3 to 20 Ton Package Units

Residential Applications •  Ice Bears 10 & 20’s completely replace AC compressors •  Ice Bears provides 24/7 cooling and energy storage •  Significant dehumidifier – reduces potential mold issues •  Apply to ductless mini-splits or traditional ducted systems •  2.5 to 5 Ton AC compressor replacement

Ice Bear Thermal Energy Storage Applications!

•  Ice Bear 20 released in January 2016 •  Ice Bear 10 in field testing, release Q1 2018 •  Residential Ice Bears use 100% of all US Patent

intellectual property and 70% of the commercial Ice Bear 30 components that have +34 million hours of operations

Hawaiian Market Observations and feedback from HECO !•  Transporting fossil fuel to HI islands to generate electricity is expensive and

is a significant carbon emitter • High cost of electricity and carbon reduction interests drove rapid adoption

of Solar PV and Wind generation resources •  Renewables have created new challenges for HECO, the “Duck Curve” •  Trade winds and hotter weather patterns have increased air conditioning

needs •  Air conditioning is a standard home appliance and humidity control system •  Electric battery operating characteristics and costs are not aligned with

residential air conditioning energy usage and heavy duty cycles •  Interconnecting thousands of residential batteries creates challenges

HECO and Residential Customer Value Proposition !Change Air Conditioning Load Patterns Without Customer Cooling Impact, Consumer save on new Time Of Use Rate!

Solar PV + Thermal Energy Storage !NetZero operation experience since 2012!

•  HI school classroom Solar/Storage application example

•  Charge Ice Batteries using off peak energy or use Solar PV to make Ice.

•  Federal Investment Tax Credits for Ice Bear when Ice is made with Solar PV
