Summary:

Through the Renewable Incentive Program, Arizona Public Service (APS) offers customers who install various renewable energy sources the opportunity to sell the credits associated with the energy generated to APS. Previously, APS only provided incentives for solar technologies, but they expanded the list of qualified renewables in 2008 to include all technologies eligible for Arizona’s Renewable Energy Standard (RES). The solar technologies eligible for a rebate include photovoltaic (PV), solar hot water, solar HVAC and solar daylighting systems. Up-front incentives for PV may be de-rated based on expected performance. Renewable energy systems are eligible for the following credit amounts:

  • Grid-tied PV (residential): $.60
  • Grid-tied PV (non-residential): Upto $1.75
  • Off-grid PV (residential): $1.50
  • Off-grid PV (non-residential): $1.35
  • Solar hot water systems (residential): $0.50/kWh estimated first-year energy savings based on OG-300 ratings, up to 50% of the system’s cost.
  • Solar hot water systems (commercial): Up to $0.75/kWh estimated first-year energy savings based on OG-300 ratings for small systems. For large SWH systems, customers can receive $0.45/kWh estimated first year energy savings, or may choose a 10, 15 or 20 year PBI. Incentives are limited to 50% of total system cost.
  • Solar HVAC systems (non-residential only):The incentive for the thermal energy delivered for cooling by a solar HVAC system is based on actual performance and ranges between $0.12/kWh-equivalent and $0.16.kWh equivalent. In addition, systems that incorporate solar thermal heating and/or solar thermal water heating are eligible for the large solar water heating PBI.
  • Solar Daylighting (non-residential only): $0.20/kWh anticipated first year savings.
  • Other solar technologies (non-residential only): PBI amount varies by contract length and technology.
  • Grid-tied wind systems (residential and non-residential):$2.25/W up to 50% of the system cost or $75,000; non-residential systems may opt for the PBI
  • Off-grid wind systems (residential and non-residential):$1.80/W up to 50% of the system cost or $75,000; non-residential systems may opt for the PBI
  • Other renewables installed by non-residential customers can apply to receive a PBI. APS will evaluate the project to determine if it is able to qualify renewable energy incentives.

APS recently established a net metering pilot program for systems of 100 kW-DC or less. Click here for more information.

Funds are assigned through a reservation process. All necessary forms can be downloaded from the program website.

APS is purchasing solar credits and renewable energy certificates to help the company meet the state’s Renewable Energy Standard (RES). Participating customers receive a one-time rebate or receive an incentive based on system output or kWh savings. APS will have access to the credits for the life of the RES program.

TEP Reduces Solar Rebate – 2012

Solar System by Arizona Energy Pros

TEP is running out of money for it’s historically generous solar program. TEP announced that the rebate will like stay at it’s $0.75 per watt incentive level. That’s amongst the lowest rebate in the state.

Solar incentives offered by Tucson Electric Power Co. (TEP)—at least in terms of commercial installations—have really taken off. Meanwhile, residential installations under the incentive programs are still somewhat behind. As such, the utility is seeking to reduce the total amount of solar incentives it offers for commercial developments in 2012, while leaving the amount for residential installations the same. That’s despite proposing to spend $8 million more on solar in 2012 than in 2011.

Tucson Electric Power Co. is asking state regulators to lower subsidies for residential customers who install solar arrays, saying the utility is running out of funding for the rebates amid a surge in demand.

Nearly 1,100 local homeowners have reserved TEP’s SunShare rebates for solar photovoltaic (PV) systems this year, surpassing the total number of residential solar power systems completed over the previous nine years combined, TEP said.

Solar installers are wary of the reduced incentive plan and caution that the steep reduction in commercial incentives could hurt the market.

“When they’re trying to fulfill their mandate, it doesn’t seem to me it’s in the interest of the whole spirit of it to put the kibosh on commercial [development],” Charlie O’Dowd, president of Abco/Westcap Solar told the Arizona Daily Star.
