Renewable Energy 7 Targets Overall RES Target rises from 1.75% of APSs retail sales in 2008 to 15% by 2025 DE Target rises from 10% of RES in 2008 to 30% in 2012 DE Target rises from 50,000 MWhs in 2008 to nearly 2,000,000 MWhs by 2025 Background
Renewable Energy 8 2009 Year-to-Date DE Results Residential 44,000,000 kWhs Non-Residential 44,000,000 kWhs Results to date: Over 2,400 participants in the program. Capacity to generate over 8.8 megawatts of green electricity. Over 2,750,000 kWhs of energy displaced by solar water heaters alone. Over $21,000,000 in renewable energy incentives paid so far. Market improvements in 2009 Federal Investment Tax Credit extended for eight years Lifting of $2,000 limit of federal tax credit for residential customers Background
Renewable Energy 9 Incentives –Up-Front Incentive (UFI): A one-time incentive paid to a customer upon successful completion of all program requirements. In exchange for this incentive, APS will receive title and ownership to all the Renewable Energy Credits (RECs) attributed to the operation of the customers system. All up-front incentives are limited to 50% of the project costs and can not exceed a total of $75,000. Incentive amounts are determined by customer rate class, technology, and application. Not all technologies are eligible for up-front incentives.
Renewable Energy 10 Incentives –Production Based Incentive (PBI): PBIs are designed to pay the customer for the environmental attributes associated with the actual production of its renewable system over time instead of an initial, up-front incentive payment. The structure for incentive payments to the customer is up to 20 years or a cap of 60% of the Real Project Cost (including acceptable financing charges), whichever comes first. The Customer is then obligated to provide APS with all Renewable Energy Credits (REC) produced for 10, 15, or 20 years, depending on the term of the agreement. Payments are paid quarterly, based on the actual production based meter reads. Incentive amounts are determined by customer rate class, technology, and application. Not all technologies are eligible for production based incentives.
