HEAT PUMP INCENTIVE �k PROGRAM I I i I HEAT PUMP BASICS • Heat pumps, like refrigerators, move heat "uphill" from cold areas to warmer ones. • Source of heat is the outside air. " • Electricity used for compressor and fans. • In use for 12 years at Alaska Sea Life Center. 3 h, x Pr 1 4 y REVERSING VALVE r r f e. -_, OUTDOOR COIL/ ^ � � • • HEAT PUMP BENEFITS ............... � ''I�IIli • More efficient than other heating systems. • More cost-effective than oil or U propane. w • Improved indoor air quality. k • Heat pumps can also serve as air �m w . - conditioners. I ror, look PF • Goals • Promote early adoption by members and installers NOW • Collect before and after data • Community spread • Mini-split units • Single head installations • 12+ Heating Seasonal Performance Factor (HSPF) • Retro-fits or new construction Up-to 1500 sq. ft • Rebate program of $500 to member and $500 to installer GOALS OF THE PROGRAM • Load growth that creates downward pressure on rates. • Heat pumps save household budget for members with propane or fuel oil. • Early adopters induce others to consider heat pumps. • Contractors develop expertise for future projects. • Member choice is always good. • Data collection for possible future heat pump rate structure. CHALLENGES • Lack of data in local climates. • Public perception — older units didn't work in the subarctic. • Financial resources (Line of Credit Program is available). • Easiest during new construction (when your furnace fails in January, you replace it with whatever is in stock). • Plumbers and HVAC firms know current technology and require training and new inventory. • Connecting homeowners with installers.

F � rr. C ro 1_ HOW TO SUPPORT INTEREST • Company should know whom to call • Provide sample wiring diagrams • Work with local electricians • Don't rely on applications and requirements documents • Have pictures available to share of 'ideal installations' • Have cheat sheets • Have a sample bill • Know your work schedule ADDITIONAL INNOVATIVE TECHNOLOGY EA t Real-time Outage Map e Outage Text Notification Energy Calculator Line of Credit Program Budget Billing Program Electronic Billing Mobile App Smart Meters This communication was paid for by Homer Electric Association, Inc. 3977 Lake Street Homer,Alaska 99603.
