2018 IRP BACKGROUND & GOALS
POWER INTEGRATED RESOURCES PLAN

Pasadena Water & Power
What is an IRP?
• IRP Details> The IRP serves as a blueprint for PWP to deliver reliable,
environmentally responsible electricity service at competitive rates over a 20-year planning period
> Recent Past IRPs City Council adopted 2009 IRP 3/16/2009 City Council adopted 2012 IRP 3/5/2012 City Council adopted 2015 IRP 6/22/2015
• IRP Development> IRPs are evolving documents IRP will be updated every 3-5 years
> Resources not considered or picked up today might be picked up in future IRPs

No strict timeline Due by January 1, 2019Updated every two-three years Mandatory five-year updateFinal product was either a detailed presentation or a report
Mandatory detailed report, specific considerations, and prescribed tables
Pasadena Water & Power
Key Issues for 2018 IRP
• SB 350 compliance> GHG emission reduction goals/alternatives> RPS goals/alternatives> Impact of transportation electrification> Impact on Disadvantaged Communities Meet reliability requirements
• Determine whether PWP remains part of the Intermountain Power Plant (“IPP”) Natural Gas Renewal Contract
• Delivery Constraints• Review of cost effective energy storage, demand
response, energy efficiency, etc.
