DWG Wind Profile Review
November 11, 2014

2. Goal of Performance Review
Stakeholder initiated review of TEPPC’s process of selecting solar and wind profiles
Ensure that TEPPC assumptions for these resources would capture the expected performance as seen by historical data
To identify possible areas of discrepancy between the CFs used in TEPPC studies and expected performance
Its important to note that CF is only one way of comparing profiles.
It has been decided that by comparing capacity factor alone would minimize the effects of different diurnal patterns and annual differences in weather

Results
Note: Size of zone proportional to total zone potential, not just wind

4. Common Case Profiles
In the 2005 NREL wind dataset there is sufficient NREL profiles to meet historical capacity factor goals for most areas without sacrificing locational diversity
Future wind sites will use the same 2005 dataset and NREL provided CF targets to meet expected wind performance throughout WECC

6. DWG Recommendation
Duke Energy, NREL and WECC staff will work together to investigate the possibility of creating new NREL profiles for use in the TEPPC 2014 study program.
Needs buyoff from NREL
Approval from TAS
Capital cost could be an issue
