Long Term Planning 21 -04 -2004 Amsterdam 3

Long Term Planning Purpose : To keep Gt. S transmission system fit for the future Challenge : Lack of reliable planning information caused by a tendency towards short term contracts and involvement of more parties Solution : Reliable planning information from shippers and NNOs 21 -04 -2004 Amsterdam 4

Gt. S annual long term planning cycle Identify grid bottlenecks Feedback And kick-off April November. April Feedback results October May August/ September Interview NNO’s 21 -04 -2004 Amsterdam 5 Send out questionnaires Receive questionnaires May. June July. August Analyze questionnaires Interview shippers

Gt. S external planning process • Executed for the first time in 2003 with a small group of shippers and NNO’s • Results were presented to these shippers in December 2003 • Gt. S wishes to repeat this process in 2004 • Today : feedback previous cycle and kick-off new cycle 21 -04 -2004 Amsterdam 6

Conclusions of 2003 external planning process (1) Three scenarios were used with varying flows at entry- and exit points Exit Julianadorp Entry Emden: Entry Balgzand Entry Oude Statenzijl: Exit Zelzate/ Zandvliet Entry Bocholtz/ ’s Gravenvoeren Entry Zelzate Exit Bocholtz/ ’s Gravenvoeren 21 -04 -2004 Amsterdam 7

Conclusions of 2003 external planning process (2) Conclusions from shippers • Large amounts of gas supplied at Emden/OSZ • Supplies from south are expected to decrease • Indications for additional exit flow in South NL 21 -04 -2004 Amsterdam 8 Conclusions from NNO’s • Large amounts of gas cannot be confirmed by Gassco • OSZ volumes are not confirmed by all NNO’s at German side • South NL conclusions confirmed by Fluxys

Conclusions of 2003 external planning process (3) • Information from shippers not consistent with information from NNO’s • Flows indicated by shippers cannot be accommodated at Gt. S entry- and exitpoints • To accommodate these flows, between € 250 and € 500 mln investments are required to increase entryand exitcapacities • Clear need for long term commitments 21 -04 -2004 Amsterdam 9

Kick-off new planning cycle Main information required • How much : volume, capacity • Where : entry/exit points • When : year, summer/winter • For whom : market segment • Circumstances : two scenarios 21 -04 -2004 Amsterdam 10

Scenarios in questionnaire • To identify divergent needs for long term investments • To ensure consistent assumptions among shippers • To provide guidance to shippers • Developed around future UK deficit 21 -04 -2004 Amsterdam 11

Scenario 1: Low transit/imports Norwegian gas Russian gas LNG 21 -04 -2004 Amsterdam 12 Middle East gas

Scenario 2: High transit/imports Norwegian gas Russian gas LNG 21 -04 -2004 Amsterdam 13 Middle East gas

Available here today for interested parties • Cover letter • Questionnaires • Scenario assumptions • Results previous planning cycle Letter with questionnaire and scenario assumptions will be made available on our web site and will also be sent to shippers 21 -04 -2004 Amsterdam 14

Online balancing (OLB) 21 -04 -2004 Amsterdam 17

Online balancing • New service to reduce imbalance risk • As from 1 April 2004 Gt. S started accepting applications for OLB – – – Main principles Basic mechanism restrictions 21 -04 -2004 Amsterdam 18

Main principles • Shipper owns or has access to flex source or storage facility with: – – – Enough bandwidth, send in & send out capacity, work volume Sufficient ramp up ramp down capacity ……. . • Shipper signs over control to Gt. S • Shipper supplies online imbalance signal Sum exits – Sum entries 21 -04 -2004 Amsterdam 19

Main principles • No interruptible entries or exits • No TTF • Only hourly measured entries & exits allowed in OLB portfolio 21 -04 -2004 Amsterdam 20

Main principles • No imbalance penalties as long as imbalances stay within agreed limits • No need to nominate for the source or storage facility • Regular evaluations, Gt. S may postpone the service in case of: – – Bad performance of source/storage facility (slow, not enough flex, …. . ) Poor quality of imbalance signal, . . 21 -04 -2004 Amsterdam 21

OLB basic mechanism Flex source or storage Nominated for by Gt. S Entries OLB Portfolio Exits On-line imbalance signal Sum Exits – Sum Entries 21 -04 -2004 Amsterdam 22

Basic mechanism OLB imbalance vs bandwidth ____ Bandwidth flex source 21 -04 -2004 Amsterdam 23

Basic mechanism OLB Gt. S flex demand vs imbalance ____ Bandwidth flex source 21 -04 -2004 Amsterdam 24

Basic mechanism OLB Volume used by Gt. S vs cumulative imbalance volume 21 -04 -2004 Amsterdam 25

OLB application • Gt. S will check whether flex source is suitable for the OLB portfolio • Technical check > 10 business days • Every change in OLB portfolio requires new technical check • Gt. S supplies format on-line signal 21 -04 -2004 Amsterdam 26

How to proceed • Questions: P. Schultz@gasunie. nl - +31 50 521 2176 – • Gt. S will organise information meetings to explain OLB in more detail 21 -04 -2004 Amsterdam 27

Implementation and Intervention Law The role of the Transmission System Operator 21 -04 -2004 Amsterdam

Tasks TSO – – – Development transmission grid Connections with other grids Capacity planning Tariffication transport services Security of supply Monitoring security of transportation Quality conversion service Balancing transmission grid Information to shippers/ neighbouring network operators Small fields policy Quality level transport 21 -04 -2004 Amsterdam 30

A great deal is realised since the Gas Law 2000 Unbundling Gasunie Trade & Supply and Gastransport Services – Introduction entry-exit system – Introduction Eurohub and TTF – Daily balancing with hourly tolerance – Tolerance services – Introduction monthly and daily contracts – Introduction interruptible services – Publication available capacity and indication usage for selected entry/exit points – Gt. S complies to Guidelines for Good Practice Madrid-forum 21 -04 -2004 Amsterdam 31

Main topics 2004 / 2005 – Online balancing – “Click and Book” – Information Services 21 -04 -2004 Amsterdam 32

The TSO as remedy? 21 -04 -2004 Amsterdam 33

Security of transportation – Sufficient transportation capacity – Public Service Obligation peak supply households – Security of supply other end users is responsibility of these end users 21 -04 -2004 Amsterdam 34

Investment and Capacity Planning – TSO will invest in Dutch natural gas transport grid: – Extension life span of existing network – Expected growth transit demand – Potential geographic shift of gas source – On economic conditions, i. e. based on rate of return transport activities 21 -04 -2004 Amsterdam 35

Long term investment planning is becoming increasingly complex High/ Many Number of involved parties Required time for information gathering Quality of information Low/ Little past 21 -04 -2004 Amsterdam 36 present future

Quality conversion and balancing – – – Need for quality conversion fluctuating Investments in quality conversion on economic basis TSO continues availability line pack and additional tolerance services on market conditions Balancing and flexibility primary to market parties Spot market in preparation 21 -04 -2004 Amsterdam 37

Need for flex • Third Phase of Liberalisation - all end users up to 1 mln m 3 of gas per year - 6 mln households • Temperature related, low load factor • More need for flexibility in transportfolio 21 -04 -2004 Amsterdam 42

Need for flex addressed by PVE • Needs and solutions identified, discussed and agreed in PVE – Platform Versnelling Energieliberalisering – Consisting of representatives of shippers, suppliers and network companies – Web site www. energieliberalisering. nl – Reports (in Dutch language) a. o. Allocation Rules Gas and Profile Methods Gas • Result: TTF Balancing Relation • Implemented by Gt. S 21 -04 -2004 Amsterdam 43

Overview of means to get flex in transportfolio • Tolerance included in transport service – • Tolerance Service – • Gt. S balances shipper’s portfolio with shipper’s own flexible source or storage Extension of TTF nomination facilities (PVE) as of 1 July 2004 – • Gt. S offers flexibility on commercial basis On Line Balancing – è Up to 13% Gt. S facilitates transfer of flexibility for domestic exits from one shipper to an other shipper Future within-day gas spot market at TTF ? 21 -04 -2004 Amsterdam 44

Zooming in • Existing TTF - Allocated as confirmed (‘Deemed’) • How can a shipper get balance gas for his domestic exits from another shipper ? • What if he already has ‘gas of his own’ and wants balance gas for domestic exits on top of that ? • What if a shipper wants to buy or sell balance gas for a specific group of domestic end users ? 21 -04 -2004 Amsterdam 45

Zooming in • Existing TTF - Allocated as confirmed (‘Deemed’) • How can a shipper get balance gas for his domestic exits from another shipper ? TTF Balancing Relation – normal TTF fee • What if he already has ‘gas of his own’ and wants balance gas for domestic exits on top of that ? TTF Own Use – free of charge • What if a shipper wants to buy or sell balance gas for a specific group of domestic end users ? End User Categories 21 -04 -2004 Amsterdam 46

Balancing Relation at TTF • Relation between upstream shipper A and downstream shipper B • Purpose is to transfer balance gas for domestic exits of shipper B • Amount is unknown at the moment of nomination • Nominated ‘xxx. B’ (xxx percentage 0 -100) • Allocation is xxx % of sum of domestic exit allocations in portfolio of shipper B – – It does not cover uncertainty in entry gas It does not cover exit at the border 21 -04 -2004 Amsterdam 47

Example of balancing relation Transportfolio Shipper A Transportfolio TTF Shipper B 3. Allocation of balancing relation ‘ 50 B’ Shipper A to Shipper B 3250 MJ 2. Allocation of balancing relation ‘ 50 B’ Shipper B from Shipper A 3250 MJ 1. Allocation of domestic exits Shipper B 21 -04 -2004 Amsterdam MJ 6500 48

Own Use at TTF • By nominating ‘Own Use’ downstream shipper B can reduce balancing relation with upstream shipper A by a certain amount and replace this with his own gas (e. g. base load from another entry) • Allocation of balancing relation at TTF equals sum of domestic exit allocations in portfolio of shipper B minus Own Use 21 -04 -2004 Amsterdam 49
