[PART 1][PART 1]

September 5, 2002Las Vegas, NV

….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”

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

Data Types – cont.Data Types – cont.

ConstraintsInterfaces – lines or collections of linesNomogramControl Area – to – Control Area

Couger Lowest Common DenominatorCouger Lowest Common Denominator Control Areas

Load ShapeUnit Commitment

does not appear to have multi-owner capability

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
