Advancing development of solar and other renewable technologies is at the core of SRP’s business.
That’s why we’ve committed to cut our greenhouse gas emissions by a third by 2035 — a goal we’ll achieve by retiring coal-fired generation and increasing the amount of solar we use to power our customers’ homes and businesses.
We’ve already invested in almost 300 megawatts of solar generation, while carefully balancing the interests of our customers. It’s our job as a nonprofit to deliver reliable power at the best possible price, all while considering the environmental impact of what we do. We do that by investing in solar and renewable technologies that deliver the biggest impact for the best value.

While we invest in solar and renewables that currently make economic sense, we’re researching technologies that will further expand the benefits of solar to all of our customers.
We opened our first solar generating facility with dedicated battery storage in May 2018 — stretching the power of solar beyond sundown. We’re working on a second such project in Chandler in conjunction with Tesla. And, we’ve incentivized our customers to explore battery storage with a rebate of up to $3,600 for a home system.
Building your solar future
The solar energy project listed below, whether completed or planned, provide a new source of renewable energy for our customers. Included for each one is an example of how many homes could potentially be powered.
Copper Crossing Solar Ranch, Florence – 20 megawatts (MW) or 3,700 homes
Queen Creek Solar, Queen Creek – 19 MW or 3,300 homes
Sandstone Solar Facility, Florence – 45 MW or 8,000 homes
Kayenta 1 – 27 MW or 17,600 homes on the Navajo Nation.
Pinal Central Energy Center, Casa Grande – 20 MW / 5,000 homes + 10 MW battery storage system.
Arizona's largest utility-scale solar energy center paired with a storage system.
Kayenta 2– 28 MW or 18,400 homes on the Navajo Nation.
Kayenta 1 and 2 combined provide power for 36,000 homes in the Navajo Nation. Proceeds from these projects and future renewable projects will pave the way for Light Up Navajo Nation.
Saint Solar and East Line Solar (in progress) – 200 MW. These plants are dedicated to commercial customers and will reduce our CO2 emissions by 1.04 million tons.
2021 – 20232021 : Central Line Solar – 100 MW. This plant is dedicated to commercial customers and will reduce our CO2 emissions by 520,000 tons. This is equivalent to the amount produced by more than 100,000 passenger cars driven in a year.
400 MW – (200 MW targeted for development on the Navajo Nation)
Two plants will open that combined together will power 100,000 homes.
Sonoran Energy Center, Buckeye area – 250 MW + 4-hour battery storage system
Storey Energy Center, Coolidge - 88 MW + 3-hour battery storage system
We’re taking bold steps to keep our state safe from the risks of climate change, while providing a reliable supply of water and power.
We are helping to bring solar energy to Arizona businesses. And that’s good for everyone.
By 2025, SRP will have 1 gigawatt more of solar energy on its grid. In this post, one of SRP's in-house energy experts explain how we're going to do that.
