Capacity Allocation and
Congestion Management Rules for Storage
Mr. Walter Boltz
ERGEG’s
Gas Focus Group (GFG)
XV Madrid Forum, 6 and 7 November 2008
Background
Improvement of storage access conditions
Most European storages fully booked
Poor transparency
Entry barrier for new entrants
Capacity hoarding
What happened?
ERGEG GGPSSO since March 2005
After Monitoring the GGPSSO twice incomplete implementation
identified
Development of specific Guidelines for storage on CAM and CMP
ERGEG Work Programme 2008: enhancement of these guidelines
ERGEG GST TF 2008
Survey on CAM/CMP and Secondary Markets
Questioning of NRAs, SSOs and storage users
Current way of development, design, acutal use and effects of the
system regarding CAM/CMP and Secondary Markets
XV Madrid Forum, 6 and 7 November 2008

Response Rate to Questionnaires
Response rate NRAs: 67%
12 NRAs out of 18 ERGEG member states with storage capacity
Response rate SSOs: 56%
29 SSOs (18 GSE and 11 non GSE members) out of 52 SSOs addresses
most answers lacking from German SSOs
(but 65% of the wgv in Germany covered)
64% of the wgv of EU member states covered
Response rate storage users: 17%
30 responses (Wholesaler, Trader, regional companies) out of 186 company
addresses
Little response from Industrial costumers and Distribution companies

Applied CAM - Answers SSOs
Developing CAM
For 80% of SSOs the main customers are affiliated companies
SSOs report to consult with customers (but mainly affiliates)
For 27% of countries (NRA answers) no legal requirements for CAM
No specific legal requirements on the design of CAM
XV Madrid Forum, 6 and 7 November 2008

Preferred CAM - Answers Storage Users
(to 75% integrated with SSOs)
XV Madrid Forum, 6 and 7 November 2008

First come first served
On average 49% of the capacity is booked by affiliates
with FCFS 80% of capacity is booked out by affiliates
On average the refusal rate was 24%
Applying FCFS the refusal rate was 34% compared
to 0% regarding CGWC
On average 20% of the capacity is locked in contracts
longer than 5 years
Applying FCFS 68% is locked in contracts longer than 5
years
Preliminary conclusions
FCFS applied by an integrated SSO prefers the affiliate
Does FCFS treat new entrants and incumbents equal?
XV Madrid Forum, 6 and 7 November 2008

Capacity goes with the costumer (CGWC)
Effective, because no refusals of capacity requests
On average 38% of the SSOs have available capacity in 2009
With CGWC 100% of SSOs have available capacity in 2009
Preliminary conclusions
The capacity allocation has to take into account the
flexibility already available in the portfolio of a shipper
Does CGWC treat new entrants and incumbents equal?
Enough capacity for other storage purposes has to be
assured
On average 62% of the SSOs also offer unbundled firm products
With CGWC 33% of the SSOs offer unbundled firm products

Applied CMP (contractual congestion) - Answers SSOs
As CMPs are applied in
different combinations,
it is not possible to give
the corresponding wgv
Developing CMP
in case of 67% there are no special legal requirements
for CMP
therefore in most cases no regulatory intervention in
case of discriminatory behaviour possible

Preferred CMP by storage users
XV Madrid Forum, 6 and 7 November 2008

Secondary Markets
36% of NRAs – requirements on a legal basis for a common
trading platform (only a small number has to place ALL
trades)
in 64% development of a common platform voluntarily
BUT users trade among themselves, SSOs do not get any
information
have to be facilitated to optimize the use of capacity
-
incentives for storage users to use bulletin boards
appropriate legal measures
obligation for SSOs to improve and enhance the platform
according to consumers/market needs
XV Madrid Forum, 6 and 7 November 2008
10
CMP – Key questions
Definition of a congestion management procedure:
(1) First step: making capacity available
(2) Second step: reallocation
How effective are the CMP regarding capacity release as
some CMP still lacking the practical test?
How capacity, traded on “secondary market”, is really made
available and transparent ?
Are “interruptibles” equal to other CMP?
How can a practicable UIOLI be designed in the storage
market?
XV Madrid Forum, 6 and 7 November 2008
11
Preliminary conclusions
CAM/CMP applied by integrated SSOs shall be designed in a
non-discriminatory way and shall facilitate competition
FCFS applied by integrated SSOs prefers the affiliate
Obligation for storage users to facilitate trades on secondary
markets are needed
How can “unused capacity” in case of UIOLI be defined?
In some countries a preferential CAM to affiliates takes place
XV Madrid Forum, 6 and 7 November 2008
12
Next steps
Assessment of different CAM and CMP
in a discussion paper for public consultation planned
by defining preconditions under which market situations the various
mechanisms are appropriate
regarding the requirements for CAM and CMP stated in the
GGPSSO
Based on assessment and the outcomes of the public
consultation GGP on CAM & CMP to storage will be drafted
