Additionally, the following changes are anticipated due to mandatory design changes initiated by the Spanish Electrical Distribution company, Endesa Distribucion:

1. The projected electrical utilities are in the 50 Hz side of the Moron AB electrical system and
they will be electrically connected to the Spanish distribution grid. As a result, the Spanish
codes, rules and procedures are mandatory in this project.
2. The electrical distribution grid company, where these utilities will be connected to, belongs
to Endesa Distribucion (EDE), that has their own standards that are also mandatory in this project,
and are subject by review and approval by EDE technical personnel.
3. EDE's review is taking place in these days, so it is expected that minor changes will occur in
project drawings and specifications as a result of EDE's recommendations. These recommendations are
not expected to increase/decrease the scope of the project, but they will mainly be associated to
parts of the installation being installed by either the Contractor or by EDE with their own means
(whose cost will remain under the project in any case, since the Contractor will have to arrange
with EDE the coordination, execution of works and commissioning of all utilities).
4. The design includes all necessary installations and utilities for the new 5 MVA transformer
bay, being a comprehensive solution. Possible changes to the design, as mentioned above, will
mainly drive to items being deleted from the drawings/specs since they will be executed by EDE and
not by the Contractor, but will be indeed executed within the project anyways.

As a result of the above, please expect some of the project documents to change. The updated documents will be made available as soon as we
receive them. Any extensions to this solicitation will be considered after receipt of the updated documents.
