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
