Gas Transit Workshop
Brussels, 24th January 2007
Gas transit regulation
(Slovakia as a country with standard TPA for transit )
Milan Sedlacek,
SPP - preprava, Slovak Republic
The presentation focuses on the treatment of gas transit
in Slovakia. Slovakia has standard TPA for gas transit. Only gas
transmission is recognised by law. Equal treatment is an underlying
principle.

2007 year:
- capacity of the
transmission system
was nearly 94 bcm/y
Slovak transmission system
Transit flows are predominant
The transit flows have varying degree of importance via-a-vis overall
gas flows in the transit country.
In some countries, transit volumes are quite substantial relative to
domestic supply.

Situation in transit regulation
Till 2003:
Fully negotiated conditions
Unregulated
Conditions agreed by parties
After 2003:
Fully regulated
Transit no longer recognised by law
Standard TPA for transmission

Transit Capacity – competition effect
Questions:
- how does this competition fit into the image of
monopolies sitting on transit lines?
- who pays for the investment? Cost based
regulation=decreasing volumes means increasing
tariffs.
- Where is the incentive to invest into new
infrastructure?
- Is this a risk free business for which only low rate of
return is justified?
Competition effect – cost based pricing
Impact of volatility in volumes on a regulated price

For the sake of simplicity, some generalisation in modelling was done.
General tendency was correctly reflected.

Entry – Exit system in practice
Although simple and user-friendly, entry-exit system is an
approximation model.

Difference in services
A final customer will often only be able to use one system,
whereas there are competing transit-systems
The service rendered in a transit contract may be different from a
domestic transportation contract : for instance, lower balancing
tolerances and higher load factor for transits ;
Balancing provisions in old transit contracts:
- Perfectly balanced
- What physically goes in = physically goes out
- Differences in magnitude of percents are not available on the
spot market or storage
Brave new world x old world certainty.
Beware - Supplier side looks to love old world more.

4. Summary
Conclusions
- Growing import dependence of Europe
- Gas transit is a security of supply issue
- Competitive routes do exist
- Stable regulatory framework is
necessary plus the need of
positive investment climate
- Standard TPA for transit works,
but sometimes there are grand
complications
