To be presented to whom it may concern:

As machinery responsible of the project HVDC tunnel (tunnel electrical interconnection between Spain and France, joint venture Dragados-EIFFAGE) certify:

that EMPOWER-rental company specialized in renting transformer, has supplied 3 electrical transformer of 250, 1250 and 1600 KVA power consumption each, covering the operating voltages 400, 5500 and 20000V.

The equipment leased to EMPOWER-RENTAL have been working continuously (24/7) for 12 months, without having caused any impact on the work, but good performance.

EMPOWER-RENTAL always addressed all the ectrical challenges in a safe and efficient manner. These achivements are mainly thanks to the high qualify technicians they have on their staff.

Their technical department successfully achieved the certification of all electrical equipment and installations in a very short space of time. 

Due to the changes occurred during the construction of the tunnel, EMPOWER RENTAL proofed their capability to be flexible with respect to the delivery of their equipment and to the designing of the instalation.

As per the non-stop working conditions of the project, EMPOWER-RENTAL provided a maintenance team available 24/7, the coordination with the workers on site was extraordinary.

In order with the aforementioned I have no objection to recommend the services of EMPOWER RENTAL, with no doubt they will find the best electrical solution for your project.

I remain at your disposal for any further information you need.
