Saving Money with SRP's Solar Rate Plan

Salt River Project (SRP), a major utility provider in Arizona, offers a variety of rate plans to support the growing adoption of solar energy among homeowners. These solar rate plans are designed to maximize the financial benefits for customers who choose to install solar panels, providing a pathway to substantial savings and energy efficiency.

Understanding SRP's Solar Rate Plans

SRP's solar rate plans are structured to accommodate the unique energy production and consumption patterns of solar-powered homes. The primary solar rate plan available to customers is the Customer Generation Price Plan (E-27). This plan includes:

  • Time-of-Use Rates (TOU): This pricing model charges different rates for electricity depending on the time of day. Peak hours, when electricity demand is highest, have higher rates. Conversely, off-peak hours have significantly lower rates. This incentivizes customers to shift their energy usage to off-peak times, maximizing savings.

  • Demand Charges: These are additional charges based on the highest amount of power used during any hour in the billing cycle. By managing and reducing peak energy consumption, customers can lower these charges.

How SRP's Solar Rate Plan Saves You Money

  1. Reduced Energy Bills: Solar panels generate electricity during daylight hours, often producing more power than the household consumes. This surplus electricity is sent back to the grid, earning credits that offset the cost of electricity consumed during non-solar hours, especially peak times. Under the TOU plan, using electricity during lower-cost off-peak hours can lead to significant savings.

  2. Incentives and Rebates: SRP offers various incentives and rebates to encourage solar adoption. These financial incentives can reduce the upfront costs of solar installation, making it more affordable for homeowners.

  3. Net Metering: While SRP has moved away from traditional net metering, their buyback program allows customers to receive credits for excess solar energy generated. These credits can be applied to future energy bills, further reducing overall costs.

  4. Energy Independence: By generating their own electricity, homeowners become less reliant on the grid, protecting themselves from rising utility rates and potential price fluctuations in the energy market.

Practical Tips for Maximizing Savings with SRP's Solar Rate Plan

  • Energy Storage: Investing in a battery storage system can help store excess solar energy generated during the day for use during peak hours, minimizing demand charges and maximizing TOU rate benefits.

  • Energy Efficiency: Implementing energy-efficient appliances and practices can reduce overall consumption, especially during peak hours, leading to lower demand charges.

  • Monitor Usage: Regularly monitoring energy usage through SRP's online tools can help identify patterns and opportunities to shift usage to off-peak times, optimizing savings.


SRP's solar rate plans offer a strategic approach for homeowners looking to save money and contribute to a sustainable future. By understanding and leveraging the specific components of these plans, such as TOU rates and demand charges, homeowners can significantly reduce their energy bills and increase their return on investment in solar technology. With additional incentives and the potential for energy independence, SRP's solar rate plans are an excellent choice for Arizona residents ready to harness the power of the sun.
