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 more difficult to calculate ex it’s ante and ex post. The forecast of DR in the IEPR very much hasn’t changed 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. – discussion is that both produce reliable savings. “voluntary” –
