Power Integrated Resource Plan

The Power Integrated Resource Plan (IRP) is Pasadena’s long-range blueprint for supplying reliable and environmentally responsible electricity at competitive rates. The IRP is based on an industry-standard, 20-year planning horizon.

About the 2018 Power IRP

Pasadena Water and Power will start to develop and update the Power Integrated Resource Plan (IRP) in early 2018. The Power IRP is a state mandate, with a due date of January 1, 2019. Prior to this mandate, PWP produced IRPs in 2009, 2012 and 2015.

As with previous IRPs, PWP will work closely with the community to determine the best resource planning options that maintain Pasadena’s environmental stewardship as well as its competitive rates. PWP looks forward to receiving input from the community as we start the IRP process.
