GGP Balancing Role and Responsibility

• Network users
• It shall be the primary responsibility of network
  users to balance their own inputs and offtakes
  over the relevant period according to the rules
  and incentives of the respective balancing
  regime.
• Transmission System Operator (TSO)
• Each TSO retains the overall responsibility for
  the economic and efficient operation of its
  system and therefore should retain a residual
  role to maintain physical balance to ensure the
  safe, secure, efficient and reliable operation of
  its system, subject to the incentives,
  information and flexibility and tools provided to
  shippers to balance their individual portfolio.
• TSOs shall provide sufficient, well-timed and
  reliable on-line based information on the
  balancing status of network users

Balancing Regime - Introduction

• Balancing regime, what matters?
• ? Balancing Zone
• ? Balancing Period
• ? Balancing Tolerances and related Incentives
• AND Balancing Information
• Balancing Information within the balancing period
  makes it possible to take corrective actions and
  avoid Incentives gt reduced balancing needs

Non Domestic Transmission BALANCING PRINCIPLES
IN OUT on Transit Routes

• Balancing System
• Imbalances on transit-routes are not allowed ?
  capacities offered to the market are maximalised
• System operated in a way that imbalances are not
  possible
• Energy balance automatically verified by Fluxys
  on an hourly basis
• If imbalance gt automatic reduction of
  Deliveries/Redeliveries in order to set balance
• Minimum balancing needs
• No imbalance penalties in transit !

• Nominations (SDT) - always balanced
• Delivery1000, Redelivery1000 per route

3 H BAPs BUT DYNAMIC POOLING OPTIMIZATION

• Dynamic pooling
• imbalances are calculated each hour on each BAP
• then, these imbalances are spread evenly across
  BAPs, within the Transfer Capacity
• resulting nearly always in the same cumulated
  imbalance as with a single BAP

Operationally close to a single BAP model
12
Daily Balancing Regime

• usual balancing regime
• ? Balancing Zone 4 balancing zones
• ? 3 types of Balancing Tolerances and related
  Incentives

13
3 types of Tolerances

• Per balancing zone
• Hourly imbalance Entry allocationsh supply
  allocationsh /- transfer allocationsh (from / to
  other balancing zone)
• 3 operational tolerances per balancing zone
• Hourly Imbalance Tolerance (HIT)
• Cumulative Imbalance Tolerance (CIT)
• Daily Imbalance Tolerance (DIT)
• allocated in function of booked capacity (MTSR)
  or additional contracted flexibility
• Incentives on
• DIT Excess/Shortfall
• CIT Excess/Shortfall
• HIT Shortfall

15
Daily Balancing Regime

• usual balancing regime
• ? Balancing Zone 4 balancing zones
• ? 3 types of Balancing Tolerances and related
  Incentives
• ? Balancing Period Day

16
DAILY Reset Settlements

• Daily reset of imbalance position
• Imbalance quantity within DIT
• reported in kind during the following day
• communicated by Edig_at_s-message/WebTrack at 0830
  the following day
• Imbalance quantity outside DIT settled in cash at
  ZIG-price
• ? Shipper starts his daily balancing period with
  a 0 position

17
Daily Balancing Regime - Conculsion

• usual balancing regime
• ? Balancing Zone 4 balancing zones
• ? 3 types of Balancing Tolerances and related
  Incentives
• ? Balancing Period Day
• BUT Binding Intra-day hourly balancing
  information communicated to shippers by Fluxys
• hourly provisional allocations (H 45)
• communicated by Edig_at_s-message/WebTrack
• balancing penalties are based on these hourly
  provisional allocations (H45)

18
Gas Accounts Settlements

• Energy Account shipper lt-gt Fluxys
• Monthly
• In cash
• Based on final allocation
• No recalculation of Imbalance penalties
• gt Decoupling of Balancing (provisional
  allocations) Gas Account Settlement issues
  (final allocations)

19
Balancing System Fluxys Summary

• For non domestic transmission
• IN OUT
• No Flexibility Needs for Shippers
• No Incentives
• For domestic transmission
• usual balancing system but with hourly binding
  balancing information so that shippers can
  continuously asset their balancing position and
  avoid incentives.
