Integrated System Plan

The electric power industry is undergoing a dramatic transformation fueled by changing customer expectations and desires, technological innovations and a focus on the environment.

To enable the achievement of SRP's 2035 Corporate Goals, SRP will begin transitioning from a traditional Integrated Resource Plan (IRP) to a more holistic and comprehensive Integrated System Plan (ISP).

Our new ISP will serve as a systemwide plan to keep SRP at the forefront of evolving technology and customer expectations.

This new Integrated System Plan:

  • Collaboratively integrates all internal planning functions for generation, transmission, distribution and customer-sided resources
  • Adapts to evolving industry demands and enhances long-term resource value for our customers and communities
  • Addresses energy challenges through the lenses of sustainability, reliability and affordability
  • Creates inclusive opportunities for active external stakeholder engagement

SRP's Integrated System Plan reports and deliverables

Reports and deliverables for SRP’s first-ever Integrated System Plan will be posted throughout the process.

Engaging our stakeholders along the way

This past summer, SRP hosted an ISP Summer Stakeholder Series to update, educate and engage with external community stakeholders regarding the ISP transition. Working alongside communities is how SRP has helped to successfully grow the Valley. This transition is no different. Working with you through this transition is essential as we chart the course to a successful ISP.

ISP Stakeholder Engagement Opportunities

Other Engagement Opportunities

  • Technical Working Sessions, open to all large stakeholders and advisory groups with an interest in the technical aspects of power system planning, will be offered around various topics of interest throughout the project.
