  1. Arizona's Renewable Energy Standard & Rebates Arizona Solar Power Society Kris Mayes, Chairman Arizona Corporation Commission January 29, 2009

  2. Energy Challenges Facing Arizona • Growth • Arizona has surpassed Nevada as the fastest growing state in the nation. • In 2007, Domestic Net Migration totaled 90,402 or 7,500 monthly • Between 2000 and 2039, Arizona’s population will more than double. By 2030 Arizona’s population will exceed 10.7 million people – becoming the 10th largest in the country. • Arizona’s electricity demand is growing approximately 1,000 MW a year • - Focus on Renewables, DSM, and Energy Efficiency to share the peak • Rising Energy Costs • Rate filings premised on volatile natural gas prices and growth. • Nationally, energy expenditures account for $1 Trillion, or 8.4% of GDP. • Infrastructure Needs • Arizona electric demand is increasing by 1,000 MW (tantamount to two new power plants) a year. • Natural Gas Infrastructure.

  3. Meeting Arizona’s Challenges with Renewables • As Arizona’s population grows each year, so does peak electrical usage. • This peak can be met by building new transmission lines and power plants as well as by the use of renewable energy, energy efficiency and demand response. • In order to meet the ambitious RES goals, as well as increasing energy efficiency programs (such as DSM, and Demand Response), it will be necessary for Arizona to create a clean energy economy. • The RES alone has created a $115 million/year market in Arizona.

  4. Energy Diversification • Facing the future in a carbon-constrained world, what will Arizona’s electric generating portfolio look like? • Since 1998, all of the power plants sited in AZ have been natural gas. • Coal represents approximately 28% of APS’ generating resources. • Coal represents approximately 69% of TEP’s generating resources. • Options for Arizona? • New natural gas • “Clean” Coal • Nuclear • Renewables

  5. Renewable Energy in Arizona • Arizona was one of the first states in the nation to implement a renewable requirement for its electric utilities. • Arizona’s Environmental Portfolio Standard was initiated in 2001 to promote the use and development of renewable energy. • In October, 2006, the Commission approved the Renewable Energy Standard, which builds upon the EPS and will once again make Arizona a leader in renewable energy, particularly solar. • The Commission established a mechanism in the rules that requires each utility to file a tariff to recover the costs of implementing the RES program.

  6. Renewable Energy • Renewable Energy is the most effective way to utilize Arizona’s resources and benefit Arizona’s environment: • Solar Potential throughout Arizona • Wind Potential in NE, NW Arizona • Geothermal • Conservation of water from not having to construct as many new power plants • Renewable Energy not only benefits Arizona’s environment but will have a positive impact on the state’s economy.

  7. RES Funds APS - $78.4 Million TEP - $29.7 Million SRP - $8 Million SSVEC - $3.4 Million Annual Total - $119.5 Million DSM and Energy Efficiency APS - $25.5 Million TEP - $6.4 Million SRP - $200 Million over the next six years Annual Total - $65.2 Million (approx) 2009 Renewable and Energy Efficiency Funds Available

  8. Environmental Benefits • By 2025, the RES rules could prevent emissions of: • 93 billion pounds of carbon dioxide • 186 million pounds of nitrogen oxide • 129 million pounds of sulfur dioxide • 1,277 pounds of mercury • RES • Will power 500,000 homes in Arizona by 2025 • 2,500 MW of renewable energy will be generated pursuant to the RES

  11. The RES: The Power of Distributed Generation • The RES rules require regulated utilities to generate 15% of their energy from renewable resources by 2025. • The RES allows utilities to use solar, wind, biomass, biogas, geothermal and other similar technologies to generate “clean” energy to power Arizona’s future.  The rules package outlines what technologies qualify and allow for new and emerging technologies to be added as they become feasible. • In addition to utility-owned projects such as Tucson Electric Power’s large solar installation in Springerville, Arizona, the Commission also required a growing percentage of the total resource portfolio to come from distributed generation – residential or non-utility owned installations.  • The distributed energy requirement starts at 5 percent of the total portfolio in 2007 and grows to 30 percent of the total renewable mix after 2011.

  18. Representative Solar Costs

  19. Funding for the RES • The RES features a sample tariff designed to pay for the expansion of the program. • For APS, the monthly charge would be the lesser of $0.007937 per kWh or • Residential Customers: $3.17/month • Small Business: $117.93/month • Large Industrial: $353.78/month • Utilities will be required to file these tariffs yearly with the Commission

  20. Distributed Renewable Energy Requirement 2007 – 5% 2008 – 10% 2009 – 15% 2010 – 20% 2011 – 25% After 2011 – 30% • Requirement that a utility shall meet half of this requirement from commercial projects and half from residential projects.

  21. Residential Solar Rebate and Tax Credits • APS and TEP customers can receive a rebate of $3 per watt in a grid-tied solar system and $2 for each watt installed in an off-grid solar system. • Residential customers are also eligible for a $1,000 state tax credit and a 30 percent federal tax credit. • Example: • For a 3.24 kW system (approximate cost $25,672), residential customers will receive $9,720 from APS and $8,702 in tax credits, taking the “out of pocket” cost to approximately $7,250. • For a 2.34 kW system, the “out of pocket” cost will be approximately $6,100

  23. Commercial Solar Rebate and Tax Credits • APS and TEP Commercial customers can receive a rebate of $2.50 per watt. • Larger commercial systems are moving to a Production Based Incentive (“PBI”) whereby customers contract with APS for credit purchase based on production (i.e. cents per kilowatt hour of production) in place of an up-front lump sum payment. • Federal tax credit of 30% of the system price • State tax credit of 25% of the system cost, capped at $25,000

  26. Looking Ahead • In 2006, 150 TEP customers installed solar PV, and 275 APS customers installed solar PV. • Statewide, Arizona will need to install over 4,200 3 kW systems next year to meet the RES goals in 2008. • This number increases to: • 5,500 in 2010 • 9,100 in 2011 • 12,000 by 2012

  27. Net Metering • What is Net Metering? • Net Metering allows customers to offset their consumption by allowing meters to turn backwards.

  28. Net Metering • On October 16, 2008, the Commission approved Net Metering Rules which are currently before the Attorney General for final approval. • Under the rules, if a consumer produces more electricity each month than he uses, he receives a credit for the electricity the next month, and then at the end of the year, the utility must true up with the customer and pay him for the electricity that he produced but didn’t use. • The most unique feature of Arizona’s net metering plan is that it has no statewide MW cap, and limits an individual who wants to net meter a home or building to 125 percent of the connected load of that building. Solar energy advocates see this feature as groundbreaking.

  29. Next Steps for Renewable Energy in AZ • 1. Increase the RES to 25 percent by 2025. • 2. Allow higher Returns on Equity (ROE) for large solar and wind projects. • 3. Add transmission to make AZ the export/import capitol for solar. • 4. Pass Solar Manufacturers’ Tax Credit to attract solar companies to AZ and realize economic development benefits of high wage high-tech solar jobs. • 5. Use proceeds from any WCI cap and trade auction to do low-income solar and bolster energy efficiency programs in AZ.
