Activites and developments 2004/05

• Co-ordination between ETRANS an GRTN further intensified.• Intensive co-operation between the TSOs of Italy and the countries at

the Northern Italian border (France, Switzerland, Austria, Slovenia) regarding cross-border items.

• New 380 kV double circuit line between Switzerland and Italy in operation since January 2005.

• Experience of new congestion at the Northern border of Switzerland and in Germany.

Congestions in Southern Germany

Key points of the latest developments:• Reduced exports of France to Italy, Switzerland during last weeks • France temporary import country (from Germany and Switzerland)• Reasons: low temperatures and the use of electrical heating systems• Germany limits its exports to France: 5600 MW till 1.1.2005.• Since 19.2.2005 Germany reduces programmes to France.• Result: increase of programmes to Switzerland by 1000 MW.• Germany announces at 1.3.2005 a limit of export-programmes to

Switzerland of 3000 MW. Since 5.3.2005 reductions take place.• Programmes between Austria and Switzerland increase by 250 MW to

500 MW. Physical flows exceed programmes by more than 1000 MW and are close to the physical limits.

• Programmes to Italy are lower than the NTC values.

Forecast based onpower plant-schedules

Forecast based on import/exportschedules

Concepts of DACF:

Results depend on quality of input data

Need of accurate load flow forecasts (DACF)

© ETRANS AG 24. Januar 2005 1222.04.23

NTC values are schedules and not physical flows.

NTC values are chiefly determined by the generation pattern and the network topology – that can change each hour.

The NTC determination must be performed in coordination with one’s neighbouring countries.

The NTC determination lies at the crossroads between electricity trading and network security (risk management, firm or not firm values ?)

The available NTC forecasts are only very rough because the NTC values can only be checked after the electricity market close (chicken or egg problem)

Status of setting up swissgrid 1/3

December 2004:• swissgrid legally founded • Not allowed to become operational due to the investigation of the

Swiss Competition Authority (WEKO)• Enlargement of the ETRANS management structure in line with

future structure of swissgridSince December 2004:

• Work on setting up swissgrid continues without delay during WEKO-investigation:

• Contractual framework between swissgrid and actual grid operators

• Concepts and business processes for future swissgrid activities (schedule management, program responsibilities, congestion management, ….)

© ETRANS AG 24. Januar 2005 2122.04.23


17 March 2005:• WEKO agrees to merge the transmission system operation in

Switzerland into swissgrid under conditions:• Obligation to allow discriminatory grid access for third parties• Obligation to publish grid use tariffs• Separate accounting for swissgrid and its shareholders• Swissgrid is not allowed to produce or to trade with electricity

except for fulfilling its tasks or to hold shares at such companies• Obligations for swissgrid’s management and supervisory board

© ETRANS AG 24. Januar 2005 2222.04.23


Future steps:• Founding companies to check the WEKO conditions• ETRANS to work further on needed business concepts for swissgrid• Start of implementation projects for new business processes• Establishment of necessary contractual framework between

swissgrid and current grid operators• Nomination of swissgrid’s supervisory board• Transfer of responsibilities to swissgrid• Transfer of man power and activities from ETRANS to swissgrid• …
