Integrated System Plan (ISP) | SRP (2024)

• 
  We will need to double or triple resource capacity over the next decade.

• 
  A least-cost energy portfolio combines new renewables with conventional power sources.

  
  In a high load growth scenario, without firm* power sources, the power system cannot satisfy reliability requirements.

• 
  We will need to evolve customer programs to help shift consumer behavior.

  
  We will need to make significant investments in new and upgraded transmission and distribution infrastructure.
