  6. WestConnect Annual Adequacy Study • Purpose – test the adequacy of most recently published WestConnect Transmission Plan (excluding conceptual projects) • A WestConnect-wide study utilizing the 5th and 10th year coordinated base cases • Perform traditional N-0, N-1 and N-2 contingency outages • Establish reliability risk of potential corridor outages with planned transmission projects in 10th year • Complete studies by August joint CCPG/SWAT meeting • Deficiencies in plan noted with sufficient lead time for subregional planning participants to investigate solutions for inclusion in the 2008 WestConnect Transmission Plan TEPPC 031408Mtg

  7. WestConnect Biennial Long Range Study • Purpose – Biennially explore conceptual long range transmission needs within WestConnect Planning Area. • A Westconnect –wide study of contemporary issues facing the industry in the 10th year and beyond. • Utilizes the 10th year coordinated base case with load forecasts and generation scenarios representative of the study time period. Study limited to power flow and only considers N-1 outages. • Initial study has two fold objective: • Provide traditional transmission reliability oriented studies in response to the TEPPC economic transmission study results, • Study WestConnect-wide integration of renewable energy projects • Complete initial study in 2009 TEPPC 031408Mtg
