Efficiency and Reliability – A Win/Win for Consumers and Utilities! ! Ice Energy & Our Ice Batteries! ! " Greg Miller" EVP Market Development" [email protected], 970-227-9406" 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" " Ice Bear Thermal Energy Storage Applications! 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 " The Ice Bear 10 and 20 Residential Energy Storage – Air Conditioning Installations" • Ice Bear 20 released in January 2016" Ice Bear 10" • 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 " Ice Bear 20" 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! Off Peak = $0.237/kWh Mid Peak = $0.149/kWh On Peak = $0.373/kWh Ice Discharge & Cooling Cycle Ice Bear Cooling Cycle Ice Charge & Cooling Cycle 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 " Ice Bear Differentiators:! Performance – Better cooling and dehumidification than traditional air conditioning! ! Environmentally" Friendly & Safe – Storage medium is tap water, no fire or hazardous chemical risks, all parts are recyclable." " ! ! 20 year life! – No repowers, No degradation, No annual cycling limitations ! " ! Fast deployment – No utility interconnection or complex construction permitting, only HVAC building permit ! ! High efficiency - 100% effective efficiency, 95% round-trip efficiencies, 14 & 16 SEER Performance. ! ! Localized Economic Development – No specialty labor, Solar and HVAC contractors can install, 40% of project cost flows back into local economy, and can be maintained by local trades Thank You .
