2012 LTPP (R.12-03-14)

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 eneration 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.

2006 LTPP

The 2006 LTPP closed with Decision D.07-12-052.  This decision approved the 2006 IOU procurement plans.  Issues of process--the ways to conduct and reports on RFOs--were covered extensively.  The decision found all three LTPPs were deficient and spotty in regards to addressing the filling their net short position with preferred resources from the EAP loading order and particularly inadequate in accounting for GHG emission reductions.  In addition, the use of independent evaluators in evaluating solicitations was established.  PG&E was authorized to procure 800 - 1,200 MW of new generation by 2015.  SCE was authorized to procure 1,200 - 1,700 MW of new resources in addition to 305 MW remaining from its standard track RFO, D.06-07-029.
