Long-Term Procurement Plan History and Related Process Documentation

The materials below provide a recent history of LTPP related staff documents, decisions, rulings, and stakeholder materials.

CPUC-CEC-CAISO LTPP/TPP Process Alignment

Infrastructure planning in California is split among the California Public Utilities Commission (CPUC), California Energy Commission (CEC), and California Independent System Operator (CAISO). These agencies collaborate to ensure that planning activities use common assumptions and are periodically updated. Details about this collaboration and the related processes are below:

"Padilla Letter" Interagency Coordination on Demand Forecast Assumptions in Procurement and Transmission Planning

On February 25, 2013, the CPUC, CEC and CAISO wrote a joint letter to Senators Padilla and Fuller, committing to a process whereby (a) the agencies coordinate on preferred resources assumptions in the CEC's demand forecast (e.g., energy efficiency, demand response, etc.) and (b) agency leadership jointly recommends a single forecast set for use in procurement and transmission planning processes.  An interagency team of senior management representatives (the joint agency steering committee or JASC) has been implementing this process since 2013.

Key Rulings and Decisions for 2012 LTPP (R.12-03-014)

The 2012 LTPP was divided into four tracks.


Track 1 (D.13-02-053) authorized procurement for reliability in two transmission constrained zones of Southern California: the Western LA Basin and Venture-Big Creek local reliability areas. The decision authorized 1400-1800 MW capacity in the West Los Angeles subarea, including 1000-1200 MW of conventional gas-fired resources, 50 MW of energy storage, and 150-600 MW of preferred resources.

Track 2 was scoped to address issues of systems reliability and operational flexibility. A Commission decision closed this track, deferring the issues to the 2014 LTPP.

Track 3 (D.14-02-040) established new long-term procurement planning rules.

Track 4, which was scoped into the proceeding on May 16th, 2013, sought to address issues of reliability in Southern California following the closure of the San Onofre Nuclear generation Station (SONGS). The Track 4 decision (D.14-03-004) was authorized an additional 500 to 800 MAW of procurement in SDG&E territory and 500 to 700 MW in SCE territory by the year 2024. Details of this authorization, including the breakdown by different resource types can be found in the ordering paragraphs of that decision.

March 14th, 2014: Decision on Track 4 Authorizing Long-Term Procurement for Local Capacity Requirements following the closure of the San Onofre Nuclear Generating Facility (SONGS).

February 27th, 2014: Decision on Track 3 modifying Long-Term Procurement Rules.

September 16th, 2013: Ruling on Cancelling Track 2 of the proceeding and modifying the schedule for Track 4.
