SPP STEP
User Input sought by SPP and SPSStudy synopsis
SPP uses various models to test system under different flow conditionsPurpose 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

SPP STEP
Project TrackingTransmission Owners or constructors response to the NTCTracking Spreadsheet - included in SPP web site, e.g. MOPC Meeting Materials (public) Many SPS projects have gone through SPP’s analysis and verification in the STEPTiming Issues between SPP Need Date and Feasible In-Service Date

Questions?

Coordination of New Delivery Point Requests and Studies
Two FERC Tariffs in play - SPP OATT and XE OATT.SPP formed Delivery Point Addition Task Force (DPATF) to develop procedures for new connection requests - status ongoing.Old Solution - new SPP Tariff request for new delivery point on load went under Aggregate Transmission Service Study -not good at all!
27
Coordination of New Delivery Point Requests and Studies
SPP has agreed that until DPATF gets a final workable procedure, Trans. Owners will study requests
Upon completion of study, study to be provided to SPP for verification, and new loads included in model (assuming customer completes request).
28
Coordination of New Delivery Point Requests and Studies
Need the following data for a new requestDesired In service dateMap showing where the new point of service is locatedLoad projection at the new location, plus any load adjustments from neighboring subs, if affected, for 10 year periodAny special details about the load - large motor, across the line start, etc. Desired connection voltageDescription of customer substation , if known.
29
Coordination of New Delivery Point Requests and Studies
Reference - Xcel Energy Guidelines for Connection of Customer Loads
Link -http://www.xcelenergy.com/docs/corpcomm/TransmInterconnectedCustLoads.pdf
Send request to Annette GallegosStudy Agreement will be preparedAfter Study Agreement is signed, work starts!
30
Coordination of New Delivery Point Requests and Studies
Nominal 60 days, unless consultant is backlogged - few being done in SPS. Upon completion of study, results sent back to requestor. Results not posted on OASIS.Customer must indicate yes to proceed, or no to stop. If nothing heard in 45 days, SPS assumes no!If Yes, connection agreement (or E&P) prepared for signature. Upon signatures of Customer and SPS, capital work order opened and physical work can start.

Generation Interconnection on Wholesale or Retail Systems
Process:SPP GI Study Methodology- If GI Request is on SPS-Owned Transmission System, SPP Will do
Studies Under the SPP OATTFeasibility - quick look System Impact - stability studies and Order 661 compliance (TNA-Insulation Coordination)Facilities Study. Related to construction. Done by SPS for SPP
Interconnect Agreement3 Party Agmt - SPP, SPS, and Generation Owner
33
Generation Interconnection on Wholesale or Retail Systems
SPP’s View of the Transmission in the SPS Balancing Authority (For GI Purposes)
SPS Transmission SystemAll of SPS-owned transmission except radial 69 kV lines.
Other Transmission SystemsMunicipalities, electric cooperatives, distribution systems, Customer-owned transmission buses or lines, and SPS-owned radial 69 kV lines
34
Generation Interconnection on Wholesale or Retail Systems
Who does GI studies on Other Transmission Systems?
SPS distribution - SPS Area EngineersElectric cooperatives, municipalities, transmission owning retail entities - the owners of those facilities or their consultants. SPP normally hasn’t done these studies. May allow them to enter SPP queue, pending a change in policy. SPP will do GI studies, today, only on SPS Transmission System.
35
Generation Interconnection on Wholesale or Retail Systems
Study Methodology for Other SystemsUp to the owner. Suggest patterning after SPP process, with consideration of the FERC Order 661 LVRT/Dynamic support issues.
What is the radial 69 kV issue on GI requests?For GI study purposes, SPP says these are not transmission but distribution lines, and thus any GI requests will not be put in their queue and transmission owner must study them. May have implications with state QF rules - unclear today.
36
Generation Interconnection on Wholesale or Retail Systems
Generation interconnection on other transmission systems provides no transmission service on SPS-owned transmission systemTransmission service must be requested separately through SPP or SPS processesParticipant in SPP Energy Imbalance Market today does not require transmission service

DescriptionConsists of developing computer based power flow and stability models that represent the transmission system for the purpose ofperforming planning studies.
Planning Studies Include: Generator & Load Interconnection Studies, Switching Studies, Motor Starting and Transient Stability Studies.
SPS as a member of SPP participates in the submission of data tothe SPP transmission planning models, with quarterly updates.SPS Powerflow Modeling Data Contact:

Customer Load Forecasts and SPP Models
We need your data!Need your forecast of peak load by seasons or years shown in SPP Model Building slidesData needs to be a Coincident Peak value, what the load is expected to be coincident with the SPS control area peak loadNon-Coincident Peak loads not usefulNo speculative new load points - new delivery points needs to have gone through study.
54
Getting Your Transmission System in the SPS/SPP Model
SPS can provide a bus number range as long as we know how many you needIntegration into SPS model - may take some time. Allow several weeks.
55
Getting Your Transmission System in the SPS/SPP Model
Transmission Contingency Switching Data needed What is your switching in specific outages?Can be modeled through our 69 kV Contingency Analysis ProgramSPS may need to know for STEP mitigation plansIf load can be transferred between stations, please tell us how much and where.
