Woodland Study Team Overview

Study cases have been posted for review. These cases were generated from the Bonneville Power modeling group's master database and were modified by ColumbiaGrid to meet flow gate targets and specified Lewis River generation levels. The cases are with and without the BPA I-5 project (Castle Rock-Troutdale 500kV) and are provided in PowerWorld binary format as well as PSS/E RAW format, saved in a 6.8 MB .zip file.

Generation Levels for the Lewis River Hydro plants are as follows:

(Some of these levels are below the agreed upon targets as the rated capability in the model did not allow for such high levels.)

	Plant Total Output in MW
Season	Merwin	Yale	Swift #1	Swift #2
Spring	135	163	234	70
Summer	115	163	234	70
Winter	135	150	234	70
