6. II.2. New capacity traded at VIP Pirineos

7. New capacity traded at VIP Pirineos: type of product and interruptible (conditions and application)
New import capacity from France to Spain on Enagas side:
Since 1st January 2017, the import capacity in the international connection with France (VIP.PIRINEOS) has increased in 60 GWh/day (during winter period) and 50 GWh/d during summer.
As a consequence, the commercial capacity of this infrastructure has grown by 36%, from 165 GWh/day during the winter period (175 GWh/d rest of the year) to GWh/day.
As a result, in compliance with the CAM Network Code, 60 GWh/day will be offered as firm unbundled capacity through firm capacity auctions during winter period (October to March).
In summer, firm bundled capacity will continue being 175 GWh/d.
On the other hand, the French operator will continue offering 60/50 GWh/day as interruptible capacity in the daily auctions.

Exceptional event situation: Inclusion of gas excess and gas shortage as exceptional events.
Remaining details have been agreed. The document is ready for signature and subsequent submission.

16. VI.2. OSBB

17. Updated parameters OSBB – VIP Pirineos
Due to the future implementation of the OSBB, it has been updated, in this case from France to Spain, the values of nomination and re-nomination from October 2015 to November 2016, with this update, it is possible to see a change in the shippers’ behavior and an updating to IR:
Ni: Last nomination of day D,
Ri: Last re-nomination of day D,
i: Interval between 1-April-2013 and the last day of the selection 81
* Previous difference between nominations and renominations, 25 GWh/day, and applying the methodology, has to be updated to the actual difference 81 GWh/day.
Updated *

18. Updated parameters OSBB – VIP Pirineos
A mathematical treatment has been done of the historical differences between the nomination and the renomination as it can see in the scatter plot below
The main conclusion are:
It’s possible to view  two different sets in the graph, the higher can be considered as “white noise” and this set contain the days with zero nomination or low nomination by the shipper with the higher contracts.  
Our proposal is not consider for the calculation of the Maximum Deviation the points into the higher set.
With this option the Maximum deviation would be 33,95 GWh/day and the IR 37,35 GWh/day
For the same reason, when the nomination will be in the higher set the OS would be 0 GWh/day.

19. Updated parameters OSBB - VIP Ibérico
In the VIP Ibérico we have updated the values of nomination and re-nomination from October 2015 to November 2016, with this update, It is possible to see a change in the shippers’ behavior and an updating to IR:
Ni: Last nomination of day D,
Ri: Last re-nomination of day D,
i: Interval between 1-April-2013 and the last day of the selection
* Previous difference between nominations and renominations, 30,4 GWh/day, has to be updated to the actual difference (aprox. 90 GWh/day)
Updated *

20. Updated parameters OSBB - VIP Ibérico
With this update, the trigger value changes from 106 to 40:
Max |Nomination – Renomination| ≤ 30,4
Historical values from to june-2015
Max |Nomination – Renomination| ≤ 90
Historical values from to november-2016
Updated

21. OSBB versus New 60 GWh/d at VIP Pirineos
Spain >>> FR
Due to the commercialisation of the 60 GWh/d of firm unbundled capacity on Enagás side, The OSBB methodology should be carefully revised :
TIGF will always interrupt more interruptible capacity than Enagás
BB is performed over the bundled capacity
Enagas will be buying- back capacity when there is still unbundled firm capacity available.
This will produce unnecessary costs for the Spanish system

25. I.2 : Capacity traded at VIP Pirineos: type of product and interruptible (conditions and application)
Since the 15th of December 2015:
Type of product : 60 GWh of (unbundled) interruptible capacity
Commercial mean : Day-Ahead auction on PRISMA (5.30pm to 6pm on D-1) for gas day D offered only if:
There is no maintenance on D
At least 98% of the total firm capacity of D has been subscribed
E.g.: over winter months, at least 0.98*165 = GWh must have been allocated via annual, quarterly, monthly and daily auctions, in order to offer interruptible capacity.

26. Conditions of Interruption:
I.2 : Capacity traded at VIP Pirineos: type of product and interruptible (conditions and application)
Conditions of Interruption:
CTE : (effective technical capacity) communicated by GRTgaz on D-1, scheduling : PITS, Prev Co, Firm and Interruptible nominations at the VIP.
nominal firm capacity (Cf) + nominal interruptible capacity (Ci) = total nominal capacity (Ct)
Consumption forecast in the zone = Prev Co
net scheduling at the PITS = PITS
Interrupted capacity level = Min [Ci ; Ct-(CTE+ Prev Co +PITS)] (b)
Example 1: CTE = 420 Prev Co = -30 PITS = -150 (injections) Cf=165 Ci=60
Equation (a): = 240 > 225 (Ct) >>> no interruption
Example 2: CTE = 400 Prev Co = -30 PITS = -170 (injections) Cf=175 Ci=60
Equation (a): = 200 < 235 (Ct) >>> interruption
Interrupted capacity level >> Equation (b): = min [60 ; 235-( )] = min [60 ; 35] = 35 GWh
35 GWh of interruptible capacity will be interrupted if all is nominated

27. I.3 Implementation of OSBB mechanism
CURRENT STATUS:

Adjustment of Md from 25 GWh/day to 34 GWh/day
Submitted to both NRAs for review on the 20/01/2017
