SPIE takes charge of Mersey road tunnel ventilation switchgear installation20 April 2021

Merseytravel has awarded energy and communications technical services provider SPIE UK a new contract.

It will be supplying, installing and replacing high voltage switchgear, low loss transformers, and high voltage, low voltage, and control cabling at the Promenade Ventilation Station, which provides ventilation and power to the Kingsway Road tunnel, which runs under the River Mersey between Liverpool and Wallasey. Four 1500kVA Wilson e3 Low Loss Transformers will be installed in order to ensure the new system is highly energy efficient.

The new high voltage switchgear is said to offer the dual benefits of energy and cost efficiency. Systems being supplied and installed by SPIE UK are forecast to save an estimated 437 tons of CO2 over the course of their lifetime, based on a 60% load factor, in comparison to the systems that they are replacing. In accordance with this high level of energy efficiency, the new high voltage switchgear will also help Merseytravel achieve significant cost savings. Based on the same 60 percent load criteria set out above the saving is estimated at £10,223 annually, delivering an improved total cost of ownership.

It is the sixth time that Merseytravel has worked with SPIE.
