Necessity for the interconnection

Spanish electrical magnitudes (Penninsular system) Demand in 2006: 252.878 MWh Maximum hourly power: 43.378 MW (27 January 2005) and Instaled generation capacity: 78.200 MW

Barcelona EC Summint, March 2002. An interchange capacity between member states of a minimun of 10% of installed generation capacity was stablished : 7.820 MW

Actual commercial interchange capacity with France: 1.400 MW Interchange capacity deficit: 6.420 MW Project proposal:

A 400 KV double circuit between Santa Llogaia and Baixas. Triplex Condor 402,30 mm2 aluminium Rating 2.441 MW/ circuito



Demand evolution

Evolution of the demand between 2002 and 2006

Demand evolution in January 2007: 3,7%

Spanish Administrative process summary

First phase: Prior consultation of the Project Summary

Second phase: Drawing up Environmental Impact Study and Preliminary Project

Third phase: Environmental Impact Statement and Administrative Authorization

Fourth phase: Drawing up detailed project implementation

Fifth phase: Approval of the Project implementation and Public Utility Statement



Second phase of the spanish administrative process: Drawing up Environmental Impact Study and Preliminary Project

Punto 1: Environmental Inventory

Punto 2: Agreement over the Spanish-French border cross- point (Awaiting agreement in conjunction with a mediator)

Punto 3: Establishment of alternative corridors for the electrical line

Punto 4: Determining of a lower impact alternative

Punto 5: Establishment of electrical line “right of way”

Punto 6: Drawing up Environmental Impact Study and Preliminary Project



February 2005: Beginning of Prior Consultation Process for the

substation and the French border)

Summary

Actions taken



REE border cross-point proposal

In the vicinity of La Jonquera, with a “right of way” from the Santa Llogaia Substation relatively parallel to the route of the TGV train Girona-Perpiñán.

This is the cross- point preferred by REE and by Generalitat de Catalunya for having the least environmental impact.

The alternative of unfolding of the current line Vic-Baixas is not possible since the Spanish part needs the construction of a new double circuit line and crosses many protected and densely inhabited zones. Also, the increase of the capacity of energy exchange is a lot smaller.



Main points to solve immediately

Appointment of the mediator determining the ideal border cross-point for the interconnection for the CE

To continue with the administrative process in both countries Definition of the alternatives of corridors for the electrical line Drawing up the Environmental Impact Study and Preliminary Project

To obtain the social acceptance of the project on both sides of the border
