Conservation and sustainability news

Conservation and stewardship are at the core of Salt River Project’s culture. We demonstrate our commitment to these values through the choices we make in operating our facilities.

Our most recent conservation and sustainability efforts are described below. Additional information is available in our sustainability and energy efficiency reports.

2016 News & Updates

Plugging new electric rides

We are charging up our support for plug-in electric vehicles: They save money and, most importantly, help reduce emissions.

Driving green

In 2016, customers in SRP’s service territory registered about 70 new EVs each month.

SRP continuously evaluates its transportation fleet, implements best practices and utilizes advances in technology. As a result of these efforts, 83% of SRP’s fleet is alternative-fueled, including biodiesel, electric and ethanol-capable vehicles and equipment.

SRP is committed to finding cleaner and more efficient ways to operate our fleet. By supporting the adoption of electric and other alternative fuel vehicles, we have the opportunity to reduce our environmental impact and assess operational costs over the long term.

Electric vehicles can receive a full charge in minutes at an EVgo charging station.

To benefit our customers, the SRP Drive Electric program provides information and education about electric vehicle ownership. It also allows us to collaborate with customers to acquire important data that will help maintain a reliable future electric grid as the market for electric vehicles increases.

SRP is partnering with EVgo, a charging network, to support five new electric vehicle fast-charging stations in SRP’s service territory. These stations are part of a collaborative effort between EVgo and SRP to improve air quality in metropolitan Phoenix.

Sustainable Portfolio

Over the last 10 years, SRP’s renewable energy resources have made up between 4% and 7% of the annual Sustainable Portfolio target. SRP’s renewable energy performance also compares favorably when defined against the Renewable Energy Standard and Tariff (REST) — a policy for utilities under jurisdiction of the Arizona Corporation Commission (ACC). While SRP is not governed by the ACC with respect to our renewable portfolio, we exceed the REST requirements when hydroelectric generation is included. SRP includes energy from run-of-river hydroelectric generation as a sustainable energy resource because of our role as one of the largest suppliers of water in the Phoenix metropolitan area.

Over the past several years, SRP has offered a variety of energy efficiency programs to help our customers manage their energy use and costs. Our goal is to offer options for customers while aiding in the management of SRP’s resources. Energy efficiency plays a key role in accomplishing this mission by cost-effectively meeting SRP’s current goals while contributing to long-term emission intensity reductions.

Currently, energy efficiency makes up 8.17%, or over half, of the annual Sustainable Portfolio target. When comparing SRP’s portfolio performance under the ACC’s Energy Efficiency Resource Standard (EERS), SRP exceeds the Arizona target.

Reducing, Reusing & Recycling

From byproduct to building product

We strive to reduce waste from our business processes whenever possible. Fly ash is a byproduct of coal power generation and would ordinarily be sent to a landfill. SRP has a goal to sell 100% of the fly ash we produce so that the material can be repurposed in construction applications, such as being used as an additive in concrete production.

SRP has partnered with the Salt River Materials Group, a business venture of the Salt River Pima-Maricopa Indian Community, to sell the fly ash from our coal-fired power plant located near St. Johns, Arizona. This arrangement affords the material a second life where it is substantially more useful than being buried in a landfill, reduces the need for virgin construction material and provides revenue for the Salt River Pima-Maricopa Indian Community and SRP.


Investment Recovery

In order from left to right, materials listed on bins with amount recycled or refurbished in tons are: Steel = 3,577 , Copper = 161,  Meters = 114, (bottom row) Aluminum = 473, Mixed Wire=43, Electronic Waste=33 and Lighting Fixtures = 8.

As part of its daily operations, SRP’s Investment Recovery department is committed to realizing the greatest return on corporate assets, including those reaching the end of their useful lives. Investment Recovery sells, refurbishes or recycles materials to optimize the return on SRP’s assets and divert materials from landfills.

Total refurbished line hardware sent back to service: 324,122 pounds, which equates to 72% landfill avoidance.

Habitat conservation

Creative solutions for forest health

The need to reduce the possibility of catastrophic wildfires in northern Arizona is critical to protect rural communities, reduce erosion and prevent sedimentation from entering the Salt and Verde river watersheds. This management is essential to protecting the water supplies of the Greater Phoenix metropolitan area and rural Arizona communities.

Working closely with the U.S. Forest Service, the State of Arizona and our partners, we are exploring efforts to improve forest health that may also provide an economically beneficial use for the biomass on our national forests.

Using debris left behind by forest thinning is one way we hope to improve the health of Arizona’s forests and watersheds.

In the forest restoration process, small-diameter trees, shrubs, branches and pine needles are harvested to reduce forest density in order to lessen the intensity of a potential fire. In the past this unusable material was burned in the forest, creating air quality issues. As a solution, SRP is exploring the possibility of using this biomass as a supplemental fuel that can be used to generate energy at our Coronado Generating Station (CGS). When properly mixed with coal in a power plant with state-of-the-art pollution control equipment, air emissions are reduced. If the pilot project is successful, co-firing at CGS with this otherwise unusable biomass material could be a win-win situation for the environment, rural communities and SRP customers.

Water-power nexus

Energy efficiency = 1,167,880 gallons saved, Renewables = 437,955 gallons saved and Hydro = 333,680 gallons saved.SRP has been bringing Greater Phoenix residents water for more than 100 years — managing what we have, planning for future supplies and promoting conservation. Our commitment to conserve means we avoided using more than 1.9 billion gallons of water in FY16 as a result of the sustainable resources in our portfolio — that’s a 314% increase from 10 years ago.


Resource Mix

To meet the needs of more than 1 million electricity customers, SRP employs a diverse portfolio of energy sources. Our robust resource portfolio is key to preserving reliability and ensuring competitive prices. SRP was proud to partner with Apple to add the 50-megawatt Bonnybrooke photovoltaic solar power plant through a 25-year power purchase agreement in September 2016. The power output from the plant is being purchased by SRP at a wholesale market rate, while Apple retains all of the environmental attributes.

Community partnerships

Championing different perspectives

Line drawing of hands.

Arizona’s economic development depends in part on championing different perspectives and ownership groups, which is one of the reasons we strive to strike a balance in our choice of suppliers. SRP educates its employees on the importance of maintaining partner diversity and engages in
initiatives that support diverse business owners by providing them with access to the resources that help them become better suppliers.

We know that when diverse businesses in our community thrive, the local economy, our customers and our company also thrive. That’s why we set yearly spending goals.

We are happy to report that in 2016 we surpassed a goal of spending 15% on diverse suppliers and are looking to set and exceed higher goals in future years.

Bringing together different perspectives, expertise and ideas is a winning proposition that enhances value and business success for all those involved.


Employees & community

SRP believes in a bright future for the communities we serve, and we are committed to investing our time and resources in the programs, projects and events that make Arizona a great place to live. SRP employees performed 37,520 hours of volunteer service in FY16 to benefit more than 200 community nonprofit agencies. Learn more about how SRP supports the community.
