Summary :• Introduction• Structure of the UGS Study• Current status of the UGS Study• Next steps : reasons for going further• Recommendations

Introduction :• As a reminder, this Study should benchmark all aspects of

underground gas storage in Europe and Central Asia• As principles :

• make efficient use of already available data (cooperate with IGU, GSE, ERGEG, IEA?…),

• Use a country by country approach (country representative) for gathering data but also take into account a market area concept

• In the 2010 WPG session, an overview of storage business and of the 90’s UGS Study results were presented

• In this 2011 session, a more detailed description of the current organization of the Study and its potential improvements will be proposed.

Current status of the Study :• The Study progress was not significant enough in 2010• Due to competition and workload, Company representatives

are less and less available for co-operations• Company managers do not feel the use of an additional

benchmark Study as there are already many studies made by other gas business bodies (IGU, Cedigaz, …) or from consultants

• The remaining work is huge (collection and analysis of data) and the working group members are too few.

25



Next steps : Why should we continue ?• A pluralist co-operation : as participants may be companies,

national bodies, consultants,.., the exchange may be more fruitful• A relevant geographic area: Europe and Central Asia makes

sense, marketwise • A multidisciplinary approach : technical, legal, commercial,

economic,..• And initially the needs for updating the Study were defined as

follows: • The market became more complex, particularly because the EU Directives for

liberalization of gas market (TPA concept) : investment decision making then became more difficult,

• Many newcomers entered the market as operators (SSOs) or as customers (TSOs, shippers, DSOs and power producers),

• Due to the further decline of EU gas production, UGS becomes and will become more and more important,

• Investors and developers of Gas Industry need to have benchmark for their investment decisions.


Recommendations : 1. Secure the current participations (done in December 2010)2. Make lobbying in the gas business community for more

participants (companies, national bodies and consultants)3. Reinforce the management of the Study using a joint

UNECE + Consultancy (benchmark oriented) team : the consultant should deal with lobbying, data collection and analysis (some offers will be proposed)

4. Find a budget for financing the consultancy support, 5. The first results of the study were initially planned at the

end of the year 2010 but they will not be available before mid 2012 even if a relevant organization is put in place.

- strategic storage might be definitely damaging

- choice of access regime should be market-oriented

- negotiated TPA should be the preferred choice wherever market conditions allow : ⇒ best regime to facilitate investments⇒ best regime to foster commercial creativity and provide best response to the demand
