High Voltage Grid Infrastructure 

At H&MV, we have a fundamental understanding of the complex challenges that high voltage grid infrastructure delivery presents to the construction programmes of Data Centres.

We have successfully completed projects across UK, EU, the Middle East and South Africa – in the process developing unparalleled expertise across multi-jurisdictional, hyperscale projects.  

What makes our projects successful? 

One of the key factors in the successful delivery of high voltage grid infrastructure is early-stage engagement with our clients.

Being involved in a project as early as concept design stage allows us to manage and co-ordinate the utility interaction and significantly reduce the design and procurement timeframes.  

Engineering & Design

Our portfolio of services includes and is not limited to:

Feasibility Studies & Planning

Tailored to client specific needs, from site selection, planning and cost assessment analysis, our detailed inspection and evaluation will assist clients in reaching an informed decision.

We can develop and deliver studies with solid content on environmental impact, grid connection methodology, sizing and different configuration arrangements. 

Design & Specification

We provide detailed design of substations from our extensive history of engineering solution delivery over the years in T&D systems.

Where specifications permit, our design philosophy will incorporate modular construction to facilitate more efficient, flexible and consistent infrastructure.

HV cabling, SCADA Systems, earthing, bonding, substation layouts, 3D Modelling all benefit from our expertise that we offer in design solutions to the client.
