0332 Removal of a users ability to allow
Quarterly NTS Entry Capacity to lapse

• Modification Proposal 0332 was discussed at the
  October Transmission Workstream
• 0332 has been amended to reflect discussions at
  October Workstream and other feedback received

  of looking at a Users exit and entry capacity
  credit position at the same time and to present

Combining exit and entry credit checks NTS
Analysis

• Analysis has been carried out to assess the
  impact of combining the entry and exit credit
  processes
• Estimated Exit Capacity Charges 2012/13
• Current entry capacity charges
• The revised level of credit has been calculated
  in accordance to Section V (exit capacity credit
  process).
• Results are a rough estimate

Analysis Results

• 44 active Entry Shippers
• 2 Shippers will be affected by exit reform and
  required to provide additional credit/security to
  National Grid NTS
• 4 Shippers (9) would be required to provide
  extra credit/security if the 2 credit processes
  were combined
• 14.75m in total
• Is there a benefit of combining the 2 credit
  processes?

The cost of providing this additional
credit/security depends on which tools are used
by the affected shippers
