Workshop on IRP Modeling Results for the 2018 Preferred System Plan


CPUC staff will host a Workshop on Integrated Resource Plan (IRP) Modeling Results for the 2018 Preferred System Plan on Monday, January 7, 2019, from 10:00am to 4:00pm PST. The purpose of this workshop is to provide an opportunity for CPUC staff and other parties to present production cost modeling and other results from analyzing the Hybrid Conforming Portfolio; to present the portfolios recommended for transmission to the CAISO Transmission Planning Process (TPP); and to solicit stakeholder input on any actions the CPUC should take based on the modeling results for the 2018 Preferred System Plan.

A quorum of Commissioners may be present at the workshop, but no votes will be taken. Other decision makers including Commissioners' advisors and administrative law judges may also attend the meeting.


Senate Bill (SB) 350, known as the Clean Energy and Pollution Reduction Act of 2015, introduced integrated resource planning (IRP) as the statewide approach to electric resource planning in California. The CPUC opened the IRP proceeding (R.16-02-007) in February 2016 to accomplish several objectives, chief of which was to develop a process for the filing of integrated resource plans. For more information and background materials on IRP, please visit the IRP Events and Materials webpage.

The workshop notice will be posted to the Commission's Daily Calendar.
