2035 Sustainability Goals

The progressive actions taken today will help ensure we can deliver on our 2035 Sustainability Goals and meet the water and power needs of today's customers and future generations.

Our goals, originally approved in 2019, are evaluated every five years to make sure they continue to meet the evolving needs of the Valley.

In March 2024, we established new, more ambitious targets, including a goal to reach net zero carbon emissions by 2050. See SRP’s revised goals.Document is a PDF

There’s power in small steps. See five-year action plans for each goal that outline 2025 milestones and initiatives.

Doing what’s right for Arizona’s future

  • 483 MW of battery storage capacity added, enough to power more than 100K homes for up to four hours

  • 92M

    gallons of water saved since FY21

    Hosted 2,275 customers at Water Conservation Expos in 2023

    Last year, business customers implemented over 1,200 energy-saving rebate projects

    616,000+

    MWh generated by our energy efficiency programs

  • In collaboration with the University of Arizona, we found a way to turn XLPE plastic from cable waste into a slurry backfill for construction projects throughout the Phoenix area

    53%

    increase in landfill diversion

    68,000+

    forest acres restored (cumulative total)

    Received commitments from five Valley cities to help with our forest restoration efforts

Sustainability success stories

A grid that's built to last 

Looking through the lenses of reliability, affordability and sustainability, SRP completed the Integrated System Plan (ISP), a holistic plan for how to build the grid of the future in partnership with community stakeholders.

Our ISP has three overarching goals:

  • Create a plan to grow SRP's energy generation through 2035.
  • Continue keeping costs affordable for our customers.
  • Meet or perform better than our 2035 Sustainability Goals.

The ISP will help us meet the evolving needs of our communities so that we are prepared to serve the Valley today and for many years to come.

Five pillars of sustainability

Carbon Emissions Reductions

SRP is committed to cutting our carbon dioxide (CO2) emissions — the primary greenhouse gas — in every aspect of our business, from power generation to our day-to-day internal operations.

Our goal is to reduce the amount of CO2 emitted by generation (per MWh) by 82% from 2005 levels by 2035 (~284 lbs./MWh) and reach net zero carbon emissions by 2050. 

We measure carbon emissions following industry best practices and using a protocol developed by The Climate RegistryOpen new site. (TCR). We use a system of measurement known as “carbon intensity.” This metric enables SRP to reflect on and compare impacts to our carbon footprint as resource mixes and customer demands change over time.

Water Resiliency

SRP was born out of the need to maintain a safe, reliable and resilient water supply. And it’s a mission to which we are still fully dedicated.

SRP manages two watersheds (Verde and Salt) comprising 8.3 million acres, seven dams and over 131 miles of canals to ensure water resiliency and an adequate supply for future use.

Our goal for 2035 is to lead efforts in water storage and drought resiliency by storing at least 1 million acre-feet of water supplies underground and pursuing the long-term viability of increasing beneficial use during flood events by up to 100,000 acre-feet.

Supply Chain and Waste Reduction

SRP is reinforcing our efforts to promote a sustainable supply chain and reduce waste. By managing our product choices and employing thoughtful purchasing strategies, we can meet and exceed sustainable best practices.

SRP is already a leader in this area and is routinely recognized for our efforts in recycling, reusing and repurposing operational waste materials to keep them out of landfills.

One goal we have in this area is to send 75% less municipal solid waste to the landfill by 2035 and 100% by 2050.

Customer and Grid Enablement

One of our goals for 2035 is to support the adoption of 1 million* electric vehicles (EVs) in SRP’s service territory and manage 90% of EV charging.

SRP will continue to ensure the reliability, flexibility and security of our grid through innovative applications, optimizing existing resources, and robust monitoring and analytics. This will enable customers to take advantage of advanced technologies and energy solutions.

Learn about the progress being made toward enabling our customers and the grid in the 2024 Customer Programs Report and in the 2024 Distribution Enablement Strategy Report.
