Greening up your home or business with renewable energy is now as easy as recycling or carpooling and will work whether you own or rent your home or business. Plus, it’s even more rewarding because when you sign up for SRP EarthWise Energy by March 10th, you’ll get two free Harkins VIP Ultimate movie passes.

With SRP EarthWise Energy, you can:

  • Match your household or business’s use with clean energy
  • Help grow demand for renewable energy
  • Make a difference you can feel good about

You simply choose to green up 50% or 100% of your electricity use with renewable energy certificates (RECs) from SRP renewables – a mix of wind, solar, biomass and/or geothermal. Your investment in SRP renewables helps increase production of renewable energy as we buy replacement RECs in the marketplace.

SRP EarthWise Energy works with all residential prices plans except M-Power and most business plans. To enroll, simply complete the form or call 602-236-4448 for residential customers and 602-236-8833 for business customers. The plan will start on your next billing cycle and you can cancel anytime.

One way to use clean energy without producing it yourself is to buy renewable energy certificates (RECs). RECs were created nationally as a way to verify energy was produced by a renewable resource.

With this program, you choose to match 50% or 100% of your household energy use at a cost of 1 cent more per kilowatt-hour. We dedicate RECs from SRP renewables that are equal to your selected amount, and then buy replacement RECs for our Sustainable Portfolio. We will provide you with an annual statement that verifies the source of RECs dedicated to you. It’s an easy and affordable way you can help advance renewable energy.

SRP EarthWise Energy makes it easy for you to green up your energy mix with renewable resources. While renewables are more affordable than ever, they still cost more than traditional resources. For 1 cent more per kilowatt-hour, you can enroll in the program and have peace of mind that you’re doing more to advance renewable energy.

Use the calculator below to estimate your additional monthly cost with EarthWise Energy.

What is renewable energy?

Renewable energy is electricity generated from sources such as the sun, wind, water, forest debris (biomass) and the earth’s own heat (geothermal). Renewable energy sources can be used to produce electricity with fewer environmental impacts.

How will subscribing to EarthWise Energy affect my bill?

When you sign up, your bill will show an EarthWise Energy line item reflecting the 50% or 100% option.

Subscribers to EarthWise Energy choose to pay 1 cent more per kilowatt-hour (kWh) for energy than non-subscribers. For example, a customer using 1,000 kWh in a given month would pay an additional $10.00 to green up 100% of their energy use, or $5.00 based on 50% of their usage that month.

When it costs SRP less than 1 cent per kWh to buy replacement RECs, any and all remaining funds will support SRP’s renewable energy and energy-efficiency programs through its tracking mechanism, the Environmental Programs Cost Adjustment Factor (EPCAF). This benefits all customers by helping to advance these sustainable options.

Why does EarthWise Energy cost more?

When you join EarthWise Energy, you are purchasing renewable energy certificates (RECs) from solar, wind, geothermal, and/or biomass projects. RECs enable you to further reduce carbon emissions associated with your power consumption above and beyond the green energy SRP already provides for all of its customers. EarthWise Energy costs more because these renewable energy resources typically have a higher cost than traditional energy resources. In addition, wind and solar produce power intermittently, for example when the sun is shining and the wind is blowing. When these sources are not producing electricity, an equal amount of other reliable generation must be available at all times to meet customers’ needs.

Can I join if I am on SRP Budget Billing?

Yes, you are eligible for SRP Budget Billing, which balances the seasonal highs and lows of your energy bill for a more consistent monthly payment. Your energy costs are averaged over the year with periodic adjustments based on changes in usage or electricity prices. You can expect to see a slight increase on your bill once you join EarthWise Energy.

Can I use SRP eBill with EarthWise Energy?

Yes, you can receive an SRP eBill notification from SRP.

Does EarthWise Energy work with any residential price plan?

EarthWise Energy is an easy way to green up any price plan except our prepay program, M-Power.

Can I join if I already am a rooftop solar or Community Solar customer?

Yes, in addition to the solar energy you generate through either your rooftop solar system or Community Solar, the remaining amount of energy supplied by SRP can be “greened up” with EarthWise Energy. If your rooftop solar or Community Solar generation provides all of your energy for the month, there will be no EarthWise Energy supplement that month.

Can I cancel the program at any time?

Yes, there is no time commitment associated with the program.

Sustainable resources provide 14.5% of SRP customers’ energy needs, which is ahead of schedule to meet our target of 20% by 2020. We plan to have more than 700 MW of utility-scale generation online by Fiscal Year 2020, which includes solar, wind, biomass, geothermal, and hydroelectric generation.
