SPS 10-YearTransmission Plan/20-Year Strategic Vision
May 2009This report contains transmission planning data that may be conceptual in nature and is subject to change. The transmission projects listed may change scope, in-service dates or may not be constructed.
2
Purpose
Summarize various planning efforts across SPP and SPSDocument 10 year plan based on current snapshotsMeet FERC Order 890 requirementsProvide roadmap that evolves to changing business and regulatory environment
3
Key Points to Take Away
SPS transmission system has expansive projectsForecasts showing increasing load growth Customer demand may vary due to economic conditions, but transmission system demand will likely continue to increase due to renewable energy production
4
Key Messages10-Year Plan Key Messages• Plan is primarily load serving and reliability based• Plan developed in coordination with SPP STEP processes• Five year capital budget created with ten year construction
identified • No speculative transmission proposed for wind energy
development• ~17,000 MW of generation interconnection requests in SPP
queue20-Year Vision Key Messages• 20 Year Vision is a conceptual plan• Three scenarios evaluated, focused on load serving • 345 kV Transmission construction expected, not 765 kV• No major transmission initiatives ( SPP EHV Plan, etc.)

Planning ProcessSPP STEP• Annual Process• Focus is overall reliability of entire SPP region• SPP conducts the studies for 10 years out• SPP invites participation in process• Study synopsis
– SPP uses various models to test system under different flow conditions
– Purpose is to determine upgrades to support increasing loads, sold transmission service
– Results are “Notices to Construct” (“NTC”) to Transmission Owners each February - letters are on the SPP website
10
Planning Process
SPS FERC 890 - Local Planning Process • Primarily aimed at 69 KV systems• Sub-regional load serving focus• Minimum of one annual meeting per year• All stakeholders invited to participate• Integrates with SPP’s FERC Order 890 process
SPP EHV Planning Process• Long-range 20-year horizon 345 kV, 765 kV plans• Coordinated with other RRCs and regions
11
Transmission
Planning DriversLoad Growth RateRegional Economic ConditionsWholesale and Retail Load Interconnections• Heavy industrial and commercial development• Currently 20 requests in study queue, 200-300 MW
SPP STEP Planning ProcessTransmission Service Studies - SPP Aggregate Study processSPP Generator Interconnection Queue - 17,000 MW, mostly windRegulatory/Environmental Considerations• State Mandates• Wind Rich Area

Planning DriversStakeholder Concerns• Cooperatives - GSEC, NM Cooperatives• Munis - WTMPA• Neighboring Utilities - Caprock, WECC (PNM, EPE,

ImplicationsProject delay – CCN process may not go forward if transmission needs changeForecast Rebound – if project is delayed, load picks up, the transmission is behind scheduleLower forecast – slower build-out, not necessarily canceled projectsLoad forecast – may not be the most significant driver as compared to generation interconnections and transmission service sold by SPP
