  1. Mod 0465: Introduction of the Planning and Advanced Reservation of Capacity Agreement (PARCA), Weighted Average PARCA Security. Jeff Chandler - 3rd October 2013 UNC Tx Workgroup

  2. This modification is the same as 0452 except for the calculation of the annual PARCA security rate. Section 14.3. SSE believe Security requirements should: Be applied consistently during Phase 2 to ensure all users are treated equally. Not be too low, such that uncovered costs are socialised. Risk of mod 452 with 0.0001 p/kWh/Day charges which results in security of only £18 k/yr. Not too high, such that it is a deterrent to new investment. Risk of mod 452 and cost of £ 5m /year from 0.0278 p/kWh/Day charges. Rational for Raising the Modification 2

  3. The non-locational PARCA security rates as calculated by NG are detailed below: A methodology to calculate the annual weighted average PARCA security rates to be included in the UNC in Section Y. The value to be updated annually in the Statement of Gas Transmission Transportation Charges. Rational for Raising the Modification 3

  4. Once reservation agreed with PARCA user, value will remain fixed for that user for the duration of the reservation term. Another PARCA user applying in another year could have a different value. Current value of PSAex = 0.0079 p/kWh/d. Current value of PSAen = 0.0098 p/kWh/d. Seek to keep calculation simple and eliminate systems work, use registered annual and enduring capacity bookings as at the time of publication of charges and use prevailing charges. On the timing and use of charge, the value would be published in August and effective from 1st October. Methodology to calculate the weighted average PARCA security value 4
