SRP Renewable Export Program

SRP Renewable Export Program

If you have a qualifying facility (with or without battery storage) that has a nameplate capacity of 100 kilowatts (kW) AC or less, SRP will purchase the exported energy, or energy and capacity.

What is the SRP Renewable Export Program?

The SRP Renewable Export Program, or the QF24 Standard Rate, is a plan for customers who have installed and are operating a qualifying facility (QF) with a generation capacity of 100 kW AC or less and want to sell excess energy to SRP. This program provides an alternative way to get compensated for exported energy and capacity. See more details, including how to determine if your generation system is eligible, in the FAQ below.

How it works

Through the SRP Renewable Export Program, customers can receive hourly market-priced* credits for energy delivered to SRP in place of other export credits. They can also pledge capacity and earn capacity credits in addition to any energy credits. All energy exported to SRP’s grid is metered at the billing meter located at your main service panel, recorded in hourly intervals, and multiplied by the external load aggregation point (ELAP) hourly market price for each specific export time.

*The market price is set by the California Independent System Operator-administered Western Energy Imbalance Market ELAP hourly price for SRP. 

How do I receive credits?

First, you should consider which of the two options to participate in.

Option 1:
Renewable Energy Export Credit
(selling energy only)
  • Once enrolled in the SRP Renewable Export Program, a customer who produces their own energy and sells it to SRP will receive an energy credit based on the market price at the time of delivery.

  • Prices change every hour, and the payment is adjusted slightly for line losses and SRP’s transaction cost per the formula above.

Option 2:
Renewable Capacity Credit
(selling energy and capacity)
  • In addition to receiving an energy credit, customers can also receive a monthly credit for providing capacity. Participants must commit to delivering capacity during at least one two-hour block each day during SRP’s capacity need hours. The available two-hour blocks can be found in the contract linked in the FAQ below.

  • Capacity need hours are 5 to 10 p.m. and a five-year contract indicating the hours capacity will be delivered is required. 

  • The capacity credit is the lesser of the capacity delivered to SRP or committed in the capacity contract and the customer’s Capacity Cost Adjuster. For customers who enroll in 2025, the Capacity Cost Adjuster is $6.16/kW per month, per two-hour block.

 How much might the market price change?

It's important to remember that the market price will fluctuate hour by hour, day by day, year by year. In the table below, we've provided the average hourly market prices for 2024. These averages could change each year based on market conditions, weather and other factors.

FAQ

The SRP Renewable Export Program is available to residential and commercial customers with qualifying facilities that have a generating capacity of 100 kW AC or less and as defined in FERC Regulations 18 C.F.R. §§ 292.101 to 292.207. The primary energy source of the qualifying facility must be biomass, waste, renewable resources, geothermal resources or any combination thereof, and 75% or more of the total energy input must be from these sources. Storage-only customers are not eligible. 

All price plans are compatible, except for those that net solar generation (also referred to as net metering). To participate in the SRP Renewable Export Program, customers must take service under a residential solar export price plan or a commercial price plan with the commercial buy back rider.

For residential customers on an export price plan, the export rate is $.0281/kilowatt-hour (kWh), so you know what to expect each month. For energy credits, under the SRP Renewable Export Program, the export credit will be determined by the real-time market price and fluctuate each hour and every day. Although the market can be unpredictable, the SRP Renewable Export Program energy credits will likely be a lower credit during the daytime while early evening or peak hours may be a higher credit. SRP’s Renewable Export Program also includes a capacity credit option for participants that commit to delivering capacity to SRP, whereas SRP’s current export rates do not offer additional capacity payments.

For commercial customers currently on the buyback rider, Renewable Export Program Credits would be slightly higher as the buyback rider uses the same market rates and administrative cost adjustment but does not provide a credit for line losses.

Exported energy is measured at the billing meter located at the main service panel, recorded in hourly intervals, and multiplied by the external load aggregation point (ELAP) hourly market price for each specific export time.

The hourly credit depends on the market price. When the market rate is positive, an energy credit is posted. If the market price is negative, a debit is posted. These debits offset the credits in the next hourly interval, meaning the customer account is adjusted based on the net sum of credits and debits. Essentially, customers participating in the SRP Renewable Export Program are credited the net amount after these adjustments. If the net amount is a negative value, no charge is billed to the customer and will result in a net-zero credit to the account for that billing cycle.

The Capacity Cost Adjuster is an approximation of how much it costs SRP to bring new resources online that will provide capacity during the hours of 5–10 p.m. The Capacity Cost Adjuster is shown in dollars per kilowatt (kW), per month and can change depending on the generation and storage resources SRP adds.

Customers will choose whether to receive a fixed or variable capacity credit. A fixed capacity credit will be the same for the entire contract term, and a variable capacity credit will fluctuate depending on the value of the Capacity Cost Adjuster. Capacity credits will be paid at $6.16/kW per month, per two-hour block. If you opt for the variable capacity credit, the price paid may change annually over the course of the contract, when the Capacity Cost Adjuster changes.

Capacity payments are for the kW delivered to the grid. To estimate your payment, divide your exported kWh by the number of hours you pledge to get the kW, then multiply kW by Capacity Cost Adjuster.

For example: If a customer commits 2 kW over a two-hour time block (4 kWh) and they deliver capacity as committed or more than their commitment, their capacity credit for the year would be calculated as such:

4 kWh x 365 days a year x $0.1012 (capacity price hourly equivalent) = $147

If you deliver less capacity than your commitment, you’ll be compensated based on your performance and the capacity contract may be terminated.

Line loss factor (LLF) refers to the quantity of energy lost during the transmission and distribution of electricity through power lines. LLF can be caused by several things, including resistance, heat and electromagnetic interactions.
