A. PG&E
In response to the August 9, 2006 ruling, PG&E proposes improvements to many of its existing programs and new programs that it expects will increase available load reductions by 235 MW by June 2007 relative to the 479 MW load drop the utility experienced in July 2006 when all programs were called. PG&E's proposals would increase potential load drop in 2008 by an additional 50 MW. PG&E also proposes stepping up its marketing efforts and making some programs more attractive by tailoring them to customer needs. New programs proposed by PG&E include an Auto DR program and a program to retrofit customer-owned back-up generation (BUG). On the basis of performance in July 2006, PG&E believes it can expect about 714 MW of load reduction in 2007 if its proposed programs are approved and implemented.
PG&E does not seek additional funding for the program improvements it describes, stating its intent to reallocate existing funds, and the possibility that it may seek additional funding at a later date. For example, PG&E states that it intends to file an application in November 2006 that will expand its AC Cycling program. A number of other proposals discussed in PG&E's August 30, 2006 are still in the conceptual phase and will be proposed formally through subsequent advice letters and applications.
The follow table summarizes PG&E's proposals:

Allow Friday notification for Monday. Increase incentives, offer additional incentive for reductions during CAISO Stage 1 emergencies. |

B. SCE
SCE proposes some modifications to its existing demand response programs and proposes to implement a new Auto DR over two years, all by reallocating funds from existing programs. SCE recommends reallocating $300,000 of its existing budget to demand bidding so that it may increase the incentives. SCE estimates this effort would make up to 25 MW available in 2007.
At the workshop, SCE also explained several administrative changes it is making to some of its programs to make them more attractive to customers and thereby increase participation. SCE has offered other demand response program changes by way of advice letter.
The following summarizes SCE's program proposals:

Auto DR |
New program to use automatic equipment to facilitate activation of demand reductions during events. Recruit ten to twenty facilities to participate in fully-automated CPP or DBP. Use TA/TI funds to encourage the installation of Auto-DR. Increase incentive to $250/kW for energy management systems installed in conjunction with Auto-DR. |

10 MW |
DBP |
Increase incentive to $0.75/kWh for summer 2007 only. "Softer" trigger. Allow standing bids. Lower minimum bid from 200 to 100kW for aggregated accounts and from 50 to 30kW for individual participants. Allow online enrollment. |

C. SDG&E
SDG&E generally proposes modifying some programs to include "soft" triggers, which would provide SDG&E with discretion as to when to call an event rather than always calling for load reductions according to pre-established criteria. SDG&E wishes to standardize trigger mechanisms across programs, and also align incentives across programs to reflect the value of load reductions in each. It plans to simplify enrollment in ways that accommodate customer interests, continue the Smart Thermostat program into 2007, improve opportunities for load aggregator participation and introduce a new program targeted at permanent load shifting that would take advantage of TA/TI funds. The program changes it seeks here would not affect SDG&E's total authorized budget and program costs would come from existing budget item.
