  1. 2009 – 2010 Southeast Inter-Regional Participation Process (“SIRPP”) Preliminary Economic Planning Results

  2. OVERVIEW • Purpose of this study is to assess the performance of the transmission systems of the Participating Transmission Owners for the five Economic Planning Studies as identified by the Stakeholders. • Assessment will include the identification of upgrades to accommodate the power flows of the five Economic Planning Studies. • Planning staff of the Participating Transmission Owners will perform the studies. • Study results will be reviewed with the Stakeholders for their input.

  3. Power Flow Cases Utilized • 2014 & 2015 Study Years • 2009 Series MMWG: 2015 Summer Peak • 2018 Study Year • 2009 Series MMWG: 2020 Summer Peak • All SIRPP areas updated with latest detailed model for the respective study years

  4. Preliminary Results Components • Thermal Analysis • Contingency Analysis to identify constrained elements/contingency pairs • Interface Transfer Capability Impacts • Potential Solutions • Transmission Projects and Cost Estimates

  5. The Five Economic Planning Studies • Entergy to Georgia ITS (2000 MW) • Study Year: 2014 • Step 2 Evaluation • MISO to TVA (2000 MW) • Study Year: 2015 • Kentucky to Georgia ITS (1000 MW) • Study Year: 2015 • SPP to SIRPP (3000 MW) • Study Year: 2018 • MISO & PJM West (SMART) to SIRPP (3000 MW) • Study Year: 2018

  6. Entergy to Georgia ITS • Year: 2014 • Transfer Amount: 2000 MW • Transfer Type: Generation to Generation • Step 2 Evaluation • Source: Generation within Entergy • Sink: Generation within the Georgia ITS

  7. Entergy to Georgia ITS Transmission System Upgrades for the SIRPP • One (1) 500 kV Line • One (1) 500 / 230 kV Transformer • Ten (10) 230 kV Lines • Four (4) 230 / 115 kV Transformers • Six (6) 161 kV Lines • Sixteen (16) 115 kV Lines Total Cost: $380,635,000

  8. EES to GA ITS – Entergy Screen Results • Projects Identified Total Cost (2014$) = $85,200,000

  9. MISO & PJM West (“SMART”) to SIRPP 3000 MW

  10. SMART to SIRPP • Year: 2018 • Transfer Amount: 3000 MW • Transfer Type: Generation to Generation • Source: Load scale (500 MW each) of the following areas • Ameren Missouri • Ameren Illinois • Alliant Energy West • Mid-American Energy • Commonwealth Edison • AEP (Ohio Power, IM Power, CS Power Zones only) • Sink: Generation within the SIRPP

  11. SMART to SIRPP Transmission System Upgrades for the SIRPP • One (1) 500 / 230 kV Transformer • One (1) 500 / 161 kV Transformer • One (1) 345 / 138 kV Transformer • One (1) 230 kV Line • Sixteen (16) 161 kV Lines • One (1) 138 kV Line • Two (2) 115 kV Lines Total Cost: $289,904,000
