User Compensation for NEC Storage Curtailment – Draft Proposal

Transmission Workstream 14/12/2005


Aims

  • Appropriately compensate Users affected by Storage Curtailment

  • Ensure that Users remain appropriately incentivised to contribute to the physical balance of the system

  • Recognise that rights to the gas held in Storage remains with the User


Proposed Compensation Amount

SAP – (ASSAP + 0.0611p/kWh)

Where, ASSAP = Volume weighted average summer SAP for previous Gas Year

0.0611p is the mod 0433 derived minimum differential between SMPBuy and SMPSell

  • Compensates for the difference between the cost of getting summer gas to the winter NBP and the value of the gas on the day.


Effect on 0052 arrangements

  • Removes the SWCQ Trade

  • Compensation claim available amount derived across whole period not for each individual curtailment event

  • Retains Curtailment Quantity Claim process (time extended to 04:00 on D)

  • Retains an after-the-day (storage allocation based) compensation adjustment mechanism.

  • Retains funding via Neutrality


Example

User Injects 25 units between curtailment periods

1st Curtailment Period

2nd Curtailment Period
