Renewable Energy

From the sun to biomass, renewable energy resources use clean, inexhaustible sources to power modern-day life.

Often referred to as clean or green energy, there are a number of characteristics that make an energy source renewable. A renewable energy source:

  • Comes from nature or a natural process, such as wind or sunshine
  • Is replenished by nature quickly when compared to conventional energy sources such as natural gas
  • Is nearly inexhaustible over the long term but is limited in the amount of energy that can be produced in the short term
  • Is environmentally friendly and plays a role in reducing carbon dioxide emissions

Our renewable energy portfolio

SRP takes a balanced and measured approach to adding renewable energy sources to meet sustainable energy targets while continuing to deliver affordable power reliably. The Board of Directors has responsibility for setting renewable energy goals and approved a new framework in October 2017 to guide the process. This framework, the 2035 Sustainability Goals, focuses on creating a sustainable future and builds upon the Sustainable Portfolio plan, which set renewable energy goals through 2020.

About our renewable portfolio

The two types of solar in SRP's mix, utility-scale and rooftop, show the amount of energy being produced by large solar facilities separate from what is produced by residential rooftop installations. Rooftop solar includes any residential solar panel units that were installed as a result of a special customer offer. SRP then retains the renewable energy credits for these.

The renewable energy capacity is updated on an annual basis at the end of SRP's fiscal year, which is May 1, 2017, through April 30, 2018.

*Currently, 55 MW of geothermal are being sold to another utility under short-term contracts and are not counted toward SRP's Sustainable Portfolio for the duration of the contracts.

More than clean air

Did you know that renewable sources reduce carbon emissions, conserve water and use waste as fuel? Learn more about how the sources in SRP's portfolio support a healthy environment.

  • Biomass: The Novo BioPower Plant in Snowflake, Arizona uses combustion fuel, like wood, to generate power. The plant is required to obtain the majority of its fuel from forest thinning, which reduces the amount of unusable wood going to the landfill and contributes to healthy forests.
  • Solar and wind: Both solar and wind generation take advantage of nature as an energy source using significantly less water than conventional power generation. Last year, SRP saved nearly 1.9 billion gallons of water by conserving energy and relying on these less-water-intensive types of generation.
  • Geothermal: Using no fuel and producing almost zero emissions, geothermal takes advantage of the heat produced by superheated water reservoirs below the Earth's surface to generate electricity. It also recycles the steam and water used by injecting it back into the Earth, renewing the geothermal resource.

Kayenta Solar facility expanded

Kayenta I Solar Facility Kayenta I Solar Facility

Property Brothers star Jonathan Scott meets with employees of the Navajo Tribal Utility Authority at the groundbreaking for Kayenta II Solar Facility.

SRP joined with officials from the Navajo Tribal Utility Authority (NTUA) and Navajo Nation leaders to break ground on the second phase of the Kayenta Solar facility, Kayenta II, this past August. Adding to the celebration was a surprise visit by Jonathan Scott of HGTV’s Property Brothers who came to learn more about what the new facility can do for the Navajo Nation.

“The second phase of the Kayenta Solar Project demonstrates the Navajo Nation’s commitment to a responsible transition to renewable energy sources,” said Speaker of the Navajo Nation Council LoRenzo Bates. “We are creating jobs and revenue from an emerging market, while remaining mindful of the associated costs, the time that it will take to transition, and other sources of energy development.” 

Kayenta II will be a 28-megwatt (MW) expansion of the Kayenta Solar facility and is expected to be commercial by June 2019. At that time, the entire Kayenta Solar facility will produce enough energy to serve about 36,000 homes. Through the partnership with NTUA, SRP will provide technical support in developing interconnection facilities for large-scale renewable development within the Navajo Nation, as well as provide procurement and financing expertise related to the development and ownership of such projects.

The Kayenta II project serves as a platform for future ventures in which NTUA and SRP will work together toward the development of up to 500 MW of renewable energy projects within the Navajo Nation over the next five to 10 years. In addition, proceeds from the Kayenta projects and future renewable projects will help pave the way for Light up the Navajo Nation, a joint program between NTUA and the American Public Power Association dedicated to the electrification of homes on the Navajo Nation and creation of a better future for local communities.

“Extending electricity to homes without has always been our goal as well as our challenge,” said NTUA General Manager Walter Haase. “Kayenta II is catalyst in that direction and will help us to improve the standard of living for many Navajo families.”

Currently, the 27.3 megawatt Kayenta Solar Project (Kayenta I) provides electricity to Navajo communities served by NTUA, generating power for an estimated 18,000 homes. At the height of construction, close to 284 people of whom 85% were of Navajo descent, worked on the project. It is expected that Kayenta II will employ a greater number of Navajo for the workforce.

“This project represents a significant addition to SRP’s growing list of renewable resources and we are extremely honored to work alongside NTUA to bring this amazing facility online. We look forward to carrying on our decades-long partnership with the Navajo Nation as we pursue new opportunities together through the Kayenta Solar Facility and other significant efforts,” said SRP Vice President John Hoopes.

In addition, the Navajo workforce was paid $5.2 million and received over 4,700 hours of specialized training in solar utility construction for the Kayenta Solar Project.  The construction also generated $3,017,055 in taxes paid to the Navajo Nation. Overall, it is estimated that $15.6 million in economic activity occurred within the surrounding communities during the construction period. Kayenta II is expected to produce similar economic benefits and salaries to the region.
