Presentation Transcript

  1. Xcel Energy – Southwestern Public Service • SPP Initiatives • Balanced Portfolio • Priority Projects • STEP

  2. SPP Priority Projects • Five 345 kV lines • 3 double ckt • $1.14 B • Postage Stamp cost allocation

  3. Principles for Successful Transmission Development • Focus on customer affordability and reliability • Ensure alignment with policy makers • Ensure cost recovery support from regulators • Coordinate with regional utilities • Open and transparent planning and development process

  4. Groups of Companies – Performing StudiesStrategic Midwest Area Renewable Transmission (SMART) StudyAlternative 2 Hybrid 345 kV and 765 kV

  5. Proposed Transmission Projects - West

  6. Evolving $3.7B $6.9B if extended to IL and IN 15.5 GW Wind 5.5 GW in SPS 2 GW in NE Underlay on SPS ~$4.0B+ $1.1B ATRR* $125M to SPS** Many assumptions Regional Proposals SPP Regional 765 kV Overlay

  7. One Key Issue – MoneyHow does Cost Allocation get decided? • Cost Allocation and Cost Recovery • Beneficiary Pays (100% agreement) • Who benefits (very little agreement) • Difficult to identify/quantify beneficiaries over time

  8. U.S. Population Density Map

  9. Overlays – State Centric Discussion - Fifty “Not” United States 33% RES Mainly In-State Renewables We Want Offshore Wind 1.25 Preference for CO Wind Preference for IL Wind We Want Michigan Wind We Want Energy Efficiency We Want to Export Solar and Wind We Want to Export Wind We Want Nuclear

  10. Upper Midwest Transmission Development Initiate (UMTDI)Lessons Learned • North Dakota, South Dakota, Minnesota, Iowa, Wisconsin Governor’s announce – September 18, 2008 – effort to determine for 5 States:1. What Transmission should be built2. Who should pay for it • Appetite for cost is small compared to full build out- MISO $ 20 Bto $ 30 B- TO’s consulting with States recommended $2-3 B of projects • Staged approach – Starter Projects/First Movers- Step function transmission build out rather than immediate implementation of a large overlay

  11. Some Drivers in Today’s Environment • Historic build outs - Addressed specific needs • August 14th 2003 Blackout- Compliance- Interest in building more transmission • Economic downturn- Interest in helping States economies • Economics of resources

  12.
