OVERVIEW OF PRESENTATION
Update on 2012 long-term procurement plan
(LTPP) proceeding and associated
procurement
Introduction to 2014 LTPP proceeding
Review of other resource planning and
procurement activities
Conclusions

2012 LTPP UPDATE

2012 LTPP UPDATE
 System requirements (Track 2) deferred to 2014 LTPP
 Local capacity requirements (Track 1) expanded to address 2013
SONGS retirement (Track 4)
 CAISO modeling identified ~4600 MW of local need, assuming ~200 MW DR,
~980 MW incremental EE, and ~460 MW DG
 D.14-03-004 reduced CAISO’s need estimate to account for some combination
of load shedding, transmission, and incremental uncommitted EE, energy
storage, demand response and customer PV resources to determine
procurement authorization:

2012 LTPP UPDATE
 SDG&E negotiated bilateral contract with
Carlsbad Energy Center for 600 MW peaker
 Application to CPUC for contract approval (A.14-07-009) filed
July 21, 2014

 SCE performed stochastic modeling of the High Load Scenario only
 Expected shortfall of 8,500 MW, with 34 -37 Stage 3 emergencies
and 1,000 GWh of expected dump energy

2014 LTPP: INITIAL CONCLUSIONS
 None of the modeling parties conclude that system
reliability need can be determined from the Phase
1a results
 Shortfall amounts do not account for 2,315 MW of Track 1&4
authorization not included in the CPUC scenarios
 CAISO: unlimited renewable curtailment potentially masking
the need for flexible resources, need further study
 SCE: any need in 2024 can be addressed in 2016 LTPP, other
ways to mitigate over-generation
 ORA: given duration of shortfall, no need for additional
capacity or further study in this LTPP proceeding
 Reply testimony due September 24 th
 Will include PG&E modeling testimony
 CAISO and SCE to submit stochastic results for
Trajectory scenario in November 13th

RESOURCE PLANNING AND
PROCUREMENT ACTIVITIES
 Renewable Energy Procurement (R.11 -05-005)
 2013 RPS purchases: PG&E 23.8%, SDG&E 23.6%, SCE 21.6%
 Appear to be on track to reach 33% by 2020
 Procurement expenditure limitation to be adopted by CPUC

RESOURCE PLANNING AND
PROCUREMENT ACTIVITIES
 Energy Storage (R.10-12-007)
 October 2013 decision set specific energy storage targets for
each IOU totaling 1,325 MW by 2020
 PG&E (580 MW); SCE (580 MW); SDG&E (165 MW)
 First RFOs anticipated December 1, 2014
 Energy Efficiency (R.13-11-005)
 Considering move to “rolling portfolios” with long term (10 yr.)
funding approval
 Would avoid program funding disruptions and embed EE in demand
forecasts used for resource planning and procurement
 Rolling portfolios will not be considered in time for setting 2015
goals and funding levels, which will continue as an extension of the
2013-14 budget cycle
17
RESOURCE PLANNING AND
PROCUREMENT ACTIVITIES
 Demand Response (R.13-09-011)
 Demand Response Auction Mechanism (DRAM) proposal
 Intended to create competitive procurement mechanism through
reverse auction and to integrate DR supply resources into CAISO
energy markets
 Aim is to launch in 2015 and achieve 5% of peak by 2020
 Settlement agreement proposes DRAM pilot auctions to be held in
2015 and 2016, many details to be determined
 CAISO/CPUC Joint Reliability Plan
 Multi-year RA requirement, market-based replacement of
CAISO backstop, unified long-term reliability planning
 Facing pushback from legislature over FERC role in
regulating RA market
18
REGULATORY PROCEEDINGS WITH
IMPLICATIONS FOR PROCUREMENT
 Residential Rate Design Rulemaking and Net Energy
Metering (NEM)
 Will new rate design and NEM rules hinder further expansion
of residential solar?
 PG&E Gas Transmission and Storage
 Combined with already approved pipeline safety
enhancement plan (PSEP), likely to result in a significant
increase in gas transportation costs for gas-fired generators
19
CONCLUSIONS
 Procurement for local resources is under way
 Results of all-source RFOs will tell us if EE and DR can compete with
other supply resources to provide local capacity
 If incremental EE and DR fall short of levels assumed in the
procurement authorization, there will be implications for reliability
 Significant modeling work remains to quantify system
reliability needs
 What level of forecasted shortfall justifies procurement?
 Long-term procurement of system resources appears at least 1 -2 years
away
 Renewable procurement seems to be reaching a plateau,
but poised for new growth phase
 Will the RPS be expanded or will there be other drivers for renewable
procurement?
 What is future of RAM and FiT?
