2. Overview Getting Hydro Data
Processing modeling coefficients to match 2008 & 09 operation to modeled 2026 loads
ColumbiaGrid sponsors GridView enhancements

3. Getting Hydro Data
WECC is working on getting hourly data from the RC, then soliciting permission to make the data publically available for the 2026 CC
Solicit data directly from other sources
I’ve started this process
Please pass on contact info to facilitate this for:
Southwest
Rocky Mountain

4. New Hydro Modeling Coeff
ColumbiaGrid has offered to process the hourly Hydro generation data to create new modeling Coefficients for PLF, HTC and min generation
An example spreadsheet will be available illustrating how the procedure is done
It will be the same basic procedure used to develop the coefficients for the core Columbia River
A HMTF meeting will be held to get approval of procedure

5. GridView Modeling Enhancements
ColumbiaGrid has sponsored to new features in GridView:
Reporting of Dump/Re-scheduled Hydro by unit
Controlling what Hydro is dispatched against:
Currently Hydro can be dispatched against Load – Wind – Solar, but it’s a global setting
It’s being changed to Load - %Wind - %Solar by region
Example:
PNW can use Load - 0% of Wind - 100% of Solar
CA/SW can use Load - 100% of Wind - 100% of Solar
