Renewable Energy

Renewable energy resources (like solar and wind power) are a cleaner, greener way to power modern-day life.

A renewable energy source:

  • Comes from nature or a natural process, such as wind or sunshine
  • Is restored by nature quickly (compared to traditional energy sources, such as natural gas)
  • Is virtually limitless (although it may be limited by the amount of energy that can be produced in a short period of time)
  • Is environmentally friendly and helps cut greenhouse gas emissions

Our renewable energy portfolio

As part of our goal to cut carbon intensity 90% by 2050, SRP is expanding our renewable portfolio. We committed to adding 1,000 MW of solar energy to our system by 2025.

About our portfolio

SRP's mix of renewables includes two types of solar: utility-scale and rooftop. Utility-scale solar is produced by large solar facilities. Rooftop solar comes from residential solar panels. If these panels are installed as part of a special customer offer, SRP retains the renewable energy credits.

More than clean air

Renewable energy sources not only reduce carbon emissions, they can also save water and use waste as fuel. Here’s how the renewables in SRP's portfolio are helping to create a healthier environment. 

  • Biomass: The Novo BioPower Plant in Snowflake, Arizona, uses combustion fuel (such as wood) to generate power. The plant gets most of its fuel from strategic forest thinning operations, which keeps otherwise unusable wood out of the landfill.
  • Solar and wind: In addition to being emissions-free, solar and wind power use about 70% less water than traditional power generation.
  • Geothermal: Geothermal power uses heat from superheated water reservoirs deep underground to generate electricity. This method uses no fuel and produces almost zero emissions. It’s also renewable – the steam and water used to generate energy can be returned below ground.

Generation flexibility

Because solar and wind power are variable resources (meaning they fluctuate), it’s important for SRP’s generation plants to have enough operational flexibility to respond to these changes in supply. SRP has added a variety of technologies, including gas and batteries, to meet increasing demand – especially during the hottest months of the year.

The Generation Flexibility project was designed to show how we could increase the capacity and flexibility of our existing fleet. Based on Phase 1 findings, SRP will focus on gas turbine and duct burner upgrades. In Phase 2, we’ll plan the implementation of the unit upgrades and expand our roadmap to include other generation assets.
