SIRPP Activity
  • November 13, 2008 – Stakeholders Conference Call to discuss study scope
  • March 16, 2009- Stakeholders Conference Call to finalize scope of revised study
  • August 19, 2009- Review/Present Report of Step 1 Study Results to Stakeholders
  • Q4 2009- Final Posting of Step 1
  • Q1 2010- Process for Step 1 and 2 begins
step 1 study assumptions
STEP 1 Study Assumptions
  • Methodology
    • Run Study Case (A) without transfer, and (B) with transfer. Each Transmission Owner applies TPL criteria to identify upgrades in Case B vs. upgrades in Case A.
  • Upgrades associated with Transfer
    • Compare Case B vs. Case A to identify any upgrades at 115 kV and above
  • Comments :
    • Upgrades are identified by each Transmission Owner that experiences a flow impact using its TPL criteria. Upgrades would be identified independent of any ultimate contract path selected
stakeholders comments to transmission owners on the five economic scenarios
Stakeholders Comments to Transmission Owners on the Five Economic Scenarios
  • Stakeholders would like each scenario to be looked at in a way that identifies the upgrades needed on the collective SIRPP systems to accommodate the requested economic transfer.
  • The stakeholders are looking for a flow-based analysis as opposed to a contract path based analysis.
  • For example, on the requested 3000 MW PJM Classic to SOCO transfer, simulate a 3000 MW generation increase in PJM Classic and 3000 MW generation decrease in SOCO and determine:
    • How the 3000 MW of flow distributes across the system (i.e., how much flows through TVA, though Duke, through Entergy, through systems outside the SIRPP, etc.)
    • What are the limitations / associated upgrades identified on the SIRPP systems
