SSG-WI Planned Resource Reference Principles for
Resource Additions (2008-2015) Minimal
Interregional Transfer Case

• Principles
• Incremental 2008-2015 resources from IRPs, to
  satisfy RPS and be consistent with other formal
  plans
• Incremental resources primarily to meet load
  growth in subareas, i.e. CA, NTAC, RMATS, SWAT
  CCPG
• If existing through 2008 resources are for
  export to other subareas, then assume same level
  of export for 2015

Conclusions

• On final iteration, Renewable Portfolio Standards
  satisfied in all six states with RPS requirements
• Principles for 2015 Reference Case satisfied in
  constructing the reference case
• The differing assumptions regarding imports and
  market availability in utilities IRPs results in
  high planning margins in some states and
  deficient margins in a couple of states
• Overall, WI has sufficient generation to meet
  load
• Model runs will point out if generation is
  deliverable to load
