Demand Response Reconnect with DRMEC Assess whether enhanced participation in DAWG would be beneficial Stakeholder input on priorities Desired outputs, required resources, timeline for above ISO CAISO TPP Whitepaper on broader inclusion of (i.e. EE/DR/customer-side DG) resources in the CAISO planning studies AMI? Microgrids? Next steps 3:30 Priorities for 2014-15 IEPR (and therefore DAWG) cycle 4:00 Adjourn Introduction to DAWG – Dickerson, DAWG; Alexander, CPUC Origins Purpose Key entities DAWG has experts from demand forecasting -- cpuc procurement, ra cpuc, caiso pto, at the same time, load modifiers feed into forecast. EE, DG, modify demand. Perhaps DR, will talk about whether there should be more. Channels of communication are both between organizations, e.g., CPUC procurement and producers of EE data. DAWG is not a party. Rather, folks file their own comments into regulatory proceedings. However, coming to common understanding of positions helps. DAWG is the intersection between these activities. DAWG also has educational purposes where folks give presentations about their own work. These are informational but helps one another get a heads up on issues and provide some opportunities to learn. Meetings are important so that organizations and groups within organizations develop data, metrics, etc. that need to be translated in order to be useful to organizations/groups that use the data as outputs. For example LTPP and RPS have different planning numbers – RPS has access to confidential data whereas LTPP does not. It is necessary that each of the organizations uses different
Much work in recent months has been on process alignment, adopted on February 27, 2014. Next LTPP workshop is to understand reliability needs for system reliability and consistent outputs for the aligned proceedings. Workshop will be posted on LTPP. There is a chart with common planning assumptions (see 12/18/2013 version below). This can evolve over the LTPP cycle.
DR plays a role in a number of proceedings including RA. One of the things that is being considered (June 2014 Resource Adequacy decision) for 2015 RA year are qualifying capacity and flexible capacity criteria for DR (supply side DR which bids into CAISO market). DR is also considered in a number of initiatives within CAISO, e.g., standard capacity products, adjustments to must offer DR are part of reliability services initiatives. Metering and telemetry are also a related topic. DR is also part of the Track I and Track IV decisions in LTPP – SCE and SDG&E have to acquire preferred resources as part of the SONGS retirement. The bifurcation decision is non-event based DR, pricing programs, etc. There is likely to be little change in terms of how that is integrated into the IEPR process. The changes will be on the supply side resources rather than on the resources. Since the DR load impact protocols have been in use there is information regarding ex ante and ex post load impacts. However, the response given temperature sensitive loads are going to vary; so it’s more difficult to calculate ex ante and ex post. The forecast of DR in the IEPR hasn’t changed very much over time. There is a high case in LTPP which assumes 5% overall of coincident system peak by 2024 – goals that may or may not be adopted. Right now DR is about 2.5% of system peak. Regarding just the load-modifying portion of DR: as of the 2013 IEPR, CEC does include both non-event based DR program and pricing in the demand forecasts. Ex post information is used where possible. This is about .02% of the load, doubling by the end of 2014. The Demand response Measurement and Evaluation Committee (DRMEC) handles impact evaluation and forecasting for DR. ACTION ITEM: Follow-up on rate-setting proceedings that are not necessarily designated as DR but are designed to modify loadshapes. ACTION ITEM: Discuss with DRMEC a webinar for (or joint meeting with) DAWG to discuss DR forecasting. ACTION ITEM: Follow up discussion of DR reliability – direct control vs. “voluntary” – discussion is that both produce reliable savings.
