Power that's ready when you are

In order to deliver energy reliably and affordably, SRP relies on a vast network of critical components such as generating stations, transmission lines and substations. Our energy portfolio includes 14 generating stations and seven hydrogeneration dams, plus renewable energy solutions like solar and biomass. In order to manage future demand, we’re developing a holistic plan called the Integrated System Plan (ISP) for how to build the grid of tomorrow in partnership with community stakeholders.

At SRP, we specialize in making sure customers with significant load demands have access to affordable, reliable power that's ready when they need it. In addition to helping you estimate your annual power costs, we’ll show you the energy infrastructure that's available near your top potential sites.


SRP power service levels

Commercial sites with monthly power demand less than 5.7 megawatts (MW) can typically be served by shared circuits if there is available power capacity in the project area. Some infrastructure work may be required.

Commercial sites with monthly power demand less than 5.7 megawatts (MW) can typically be served by shared circuits if there is available power capacity in the project area. Some infrastructure work may be required.

Commercial sites with monthly power demand between 5.7 MW and 10 MW require service via dedicated power line circuits or “feeders” constructed and extended to the customer site. The customer’s power is served by two dedicated distribution-level power circuits, which includes a second for backup power reliability. Depending on available capacity, a substation bay expansion may be needed. The ultimate power load served at this level is dependent on power study work.  

  • Requires trenching and conduit for the power line extension to the nearest substation with available capacity. 
  • If a substation bay expansion is required, a new bay is added to the nearest distribution substation with available capacity. 
  • The customer is responsible for the cost of the distribution line extension to the site, trenching and conduit, as well as easement acquisition.

  • The customer is responsible for the cost of the distribution line extension to the site, trenching and conduit, as well as easement acquisition.  

Commercial sites with monthly power demand between 10 MW and 149 MW require construction of a dedicated substation on site fed by the 69 kV system.  

  • Ideal locations are close to transmission power lines (69 kV and above). However, this does not guarantee capacity is available.  
  • Dedicated substations require transmission analysis to review system impacts and available capacity on the power system.  
  • The customer is responsible for the cost of the dedicated substation, transmission line extension to the site as well as easement acquisition.

  • Dedicated substations require transmission analysis to review system impacts and available capacity on the power system.  
  • The customer is responsible for the cost of the dedicated substation, transmission line extension to the site as well as easement acquisition. 

Commercial sites with monthly power demand at, or greater than, 150 MW will be served by SRP’s Bulk Electric System. This means they will connect to transmission power lines at the 115 kV level and above.

  • Ideal locations are in proximity to transmission power lines 230 kV and above. However, this does not guarantee capacity is available.
  • Dedicated substations require transmission analysis to review system impacts and available capacity on the power system.
  • To ensure transmission lines meet the needs of a new dedicated substation, often a transmission line extension is required.
  • Construction of new transmission lines may require the customer to seek a certificate of environmental compatibility (CEC) from the Arizona Corporation Commission’s (ACC) Power Plant and Transmission Line Siting Committee.
  • The customer is responsible for the cost of the dedicated substation, transmission line extension to the site as well as easement acquisition.
  • At the 230 kV level, the client can typically be responsible for securing two 100-foot easements for each pole line to the connection point.
