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 is in the process of developing the 2018 Power Integrated Resource Plan (IRP). 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.

Recommended 2018 Power IRP Strategy

The IRP will be going to the Environmental Advisory Commission (EAC), Municipal Services Committee (MSC), and City Council for recommendation for approval. The IRP will be presented at the EAC on November 13, 2018 and MSC on November 27, 2018.  PWP plans to present the Power IRP proposal to the Pasadena City Council in December 3, 2018, and to submit the Power IRP by January 1, 2019.

The recommended strategy of the 2018 IRP includes:

  • Meeting the SB 100 Renewable Portfolio Standard  target of 60% RPS by 2030
  • Meeting the California Air Resources Board recommended planning greenhouse gas (GHG) emissions reduction target of at least 75% GHG reduction (from 1990 levels) by 2030
  • Removing coal from the PWP power portfolio by June 2027
  • Recommending not to move forward with the IPP Renewal Project, the 50 year natural gas project, that replaces the IPP coal facility
  • No new long term commitments to commitments to fossil fueled resources, to meet our energy needs
  • Utilization of a Social Cost of Carbon for long-range planning purposes (as a dispatch penalty in the production cost model)
