….from Pacificorp’s 7/31/02 presentation….from Pacificorp’s 7/31/02 presentation Set up a complete data set for Y2008: generators
(capacity, costs, availability); loads by control area (annual energy, monthly maximum demand and hourly demand profile); and transmission network (a complete WSCC system or other as specified by WG)

Data Use/ConfidentialityData Use/Confidentiality Per previous meeting, the SSG-WI database
needs to be public
Per PacifiCorp: Database needs to be built from the “ground up”
![Page 4: SSG-WI System Model Data Requirements [PART 1] September 5, 2002 Las Vegas, NV](https://reader035.vdocument.in/reader035/viewer/2022081516/551b7418550346d31b8b6205/html5/thumbnails/4.jpg)
Data TypesData Types Load Flow – WSCC
Network Data – busses, lines, transformers, generators Resource Data
Dispatchable – thermal unitsNon-dispatchable – hydro, wind, solarFuel - cost
Load DataLoad distribution (within Control Area – per load flow)Load Shapes (by Control Area)Load Forecast

Primary Decision Point for WG – how many control areas?

Data CoordinatorsData CoordinatorsNetwork:
– Load Flow – WSCC/WECC– Decide on which case to use– Secure WECC permission– Data Scrubbing
Load ForecastsGenerators
– Heat Rates and Fuel Price: where do we get this from public sources? What source do we rely on?
Load/Resource Profiles – EEI Format– Each Control Area– Non-Dispatchable Resources
Area/Regional Contraints
