Western States in Peak Footprint PV Installations Source EIA Capacity from Utility and Small Scale Facilities Does not include residential and other distribution connected PV systems State Total MW AZ 2528.9 CO 707.9 ID 127.4 MT 8.1 NV 149.6 NM 604.5 UT 972.3 WY 2.2 CA 13960.5 OR 181.3 WA 78.9
Peak Gathering Data For Study Build a case using forecast data Estimate loss of PV generation using numbers from EIA May estimate “worst case” BTM PV installations in more significantly affected systems Historical reserves to make up loss of PV Other known Operating Plans being enacted on 8/21/17 (e.g. more reserves, dispatching additional gen, etc.)
Peak Collaboration with NREL Much speculation regarding how much behind the meter (BTM) PV is on the system NREL in collaboration with Peak to analyze Aug 21st data to determine % BTM PV Goal is to produce BA level percentages May also assist in producing study cases to be used in preparation of the event. Details TBD.
