1. Methodology• ETSO• REN & REE
2. Evolution• Structural (investments)• Not Structural (investigation)
3. Use• Yearly : 2001-2006• Monthly : Jan-Nov 2007
o MIBEL (>1-Jul-2007)
Interchange Capacity between Portugal and Spain
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 3
ETSO – European Transmission System Operator
• TTC – Total Transfer Capacity• NTC – Net Transfer Capacity
o NTC = TTC – TRM
• TRM – Transmission Reliability Margin• AAC – Already Allocated Capacity• ATC – Available Transmission Capacity
o ATC = NTC – AAC
Methodology – ETSO
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 4
Methodology – ETSO
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 5
1. Parallel Flows• It is not possible to define an NTC for all pairs of
countries
Methodology – Limitations
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 6
2. Program versus Physical• The generation Shift is not equal to Physical flow
change at the tie-lines
Methodology – Limitations
o NTF – Notified Transmission Flow
o TTF – Total Transfer Flow
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 7
• Generation Shifto Start with base case including some Import/Export flowo Increase Generation on system A
Limited by Generation Capacity
o Decrease Generation on system B
Methodology – Computation
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 8
• Export of Portugal– It maybe limit Generation capacity in Portugal– The hydro (run-of-river) is not mobilized– The renewable (wind) is also not mobilized
Methodology – Computation
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 9
• Import from Spain– There is no limit in the Generation capacity, since we
may import from France (in theory)
Methodology – Computation
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 10
• Generation Shifto No load changeso TSO A computes
For Generation in A It uses economic merit order (economical signal)
For Generation in B It uses pro-rata order (no economical signal)
These differences may be justified because the limit from A to B computed by A is different from the computation by B.
• In ETSO all TSO must provide reference save cases (winter and Summer) Where all network elements are available (not realistic)
Methodology – Computation
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 11
• Summer and Winter NTC in Europe
www.etso-net.org
Methodology – ETSO
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 12
• New procedure on the Iberian Methodology– Horizons– Time date to deliver data and results– Unavailability of network and generation
• That influence the Interchange Capacity• More realistic than ETSO
– Generation order merit• More realistic than ETSO
Methodology – REN and REE
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 13
• New procedure on the Iberian Methodology– TRM - Transmission Reliability Margin
10% of the Capacity with a minimum of 100 MW Covers errors on the network model used for the computation Covers Load forecast errors Covers Renewable Generation forecast errors
– Network security rules for each TSO Contingency analysis is also applied in foreign network Each TSO checks its network limits
Overload in foreign network is ignored Different results may show up !
Methodology – REN and REE
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 14
• Horizons– Yearly
• REN : Monthly discrimination (ERSE, Hydrology)• REE : Season discrimination
– Trimester• Work day and weekend peak and off-peak discrimination
– Monthly• Daily peak and off-peak discrimination
– Weekly• For two weeks• Hourly discrimination
Methodology – REN and REE
CEE’07 - International Conference on Electrical Engineering Coimbra, 28 November 2007 15
• Firmness (situation before MIBEL)

• PTR – Physical Transmission Rights– After the Capacity is given in the daily market, if there is
a need to reduce the interchange capacity, the TSO uses “counter trading” to guarantee the Transmission Rights
• Auction
– “Use it or get paid for it”

MIBEL – Iberian pool
Market Split – Why?
• If the Interchange Capacity is limiting the Market, it will split the Iberian Market and we have two market prices: Portuguese and Spanish.

Conclusions
• What is the amount of interchange capacity need for MIBEL ?– In the beginning, the prices are too different, thus we
need more capacity than what we have– In the end, when we have the same price, zero capacity
is enough– New players installing additional generation in Portugal
will decrease the pressure (2009/2010)
• What is the target of the Iberian TSO (REN and REE) ?– 3000 MW in the next decade
Interchange Capacity between Portugal and Spain
