Helping transform the electricity sector
Delivering both transmission and distribution projects across the UK

  • Helping our energy clients improve their electricity assets to increase their operational life
  • Meeting the challenges of fluctuating energy demands by replacing and improving transmission and distribution infrastructure.

Our clients in the energy sector benefit from our significant capabilities in power transmission and distribution in the installation, jointing, commissioning and servicing and maintenance of cable infrastructure and associated equipment from 11kV up to and including 400kV.

We offer complete engineering services for electricity transmission and distribution which includes cable installation, removal, decommissioning and faults and services whilst we continue to build our substation and switchgear operations.

We provide full end to end services using our own direct staffing which includes feasibility studies, design, civils, installation, jointing, reinstatement and commissioning.

We own our own fleet of oil lorries and degasifiers to service the fluid filled cable industry which together with our leak detection capability provides a true complete solution to this specialist area of cable asset management.

Our work continues to ensure the delivery and reliability of a safe and secure supply for energy users nationwide whilst upgrading systems to support growing demands generated by renewable energy sources such as wind, solar, hydro and tidal power.

We support our clients in delivering effective capital expenditure by improving existing assets to increase their operational life and efficiency. Safeguarding supply by upgrading and replacing infrastructure and fast response to provide repair and maintenance services.

We work closely with our clients to assist them in meeting regulatory requirements whilst achieving the maximum return from their assets. We develop innovative engineering methods to achieve this, constantly developing safer and more cost effective work practices such as NICE (None Intrusive Cable Extraction) which removes cables up to 400kV from the ground without the need for open cut trench for the length of the cable thus reducing costs, disruption and mitigating environmental impacts.

NICE (Non Intrusive Cable Extraction)

JSM have launched NICE (Non Intrusive Cable Extraction) providing a unique and now proven method for removing decommissioned and redundant fluid filled underground cables normally free of charge.

Although subject to survey, JSM is confident that they will be able to remove cables for the cost of the retained asset and as such, no charge to its client

JSM have developed an innovative method for removing underground decommissioned fluid filled cables without the need for traditional open cut trenching for the length of the cable thus mitigating any environmental risks of leaving the cables buried.

Not only does this method represent huge cost savings but significant physical advantages by reducing disturbance and disruption but also reduces environmental impacts during the extraction process over traditional open cut trench methods.
NICE has been fully developed by JSM, successfully trialled and is currently delivering projects in the UK.

The benefits don’t end there, not only are JSM able to remove buried cable using this method but have the ability to replace the void made by the removed cable with new assets such as ducting and new cable at the same time. This means making the most of the route and/or crossing for future infrastructure installation and circuit overlays thus providing huge saving in terms of both time and costs.

We at JSM are confident this will very soon become the industry best practice for the removal of underground cables.

We at JSM will be delighted to demonstrate how we are able to achieve this, until now elusive method of complete cable extraction.
The method described in this method statement (“NICE” – Non-Intrusive Cable Extraction) [and the specially designed equipment to implement the NICE method are proprietary to JSM Construction Limited. NICE is a trade mark of JSM Construction Limited, and the NICE method is patent pending (number GB1408164.0).
