During this project SHETL will undertake a literature review of the available composite, laminated and modular pole alternatives to wooden poles. These alternative poles have not been used in the UK but have been successfully used in North America. A desk top review will be undertaken to ascertain all the potential benefits and costs of these alternative methods through the full product life cycle from procurement, installation, maintenance through to disposal. In addition, the safety case and product specifications will be reviewed to ensure that they will meet the required UK standards.The scope of the project will include the following:

· Identify the requirements and standards that govern transmission voltage of 132kV;

· Assess new structure design options, including the use of new materials, from a review of what is being built internationally;

· Consider designs that should be taken forward for field trials and tests;

· Assessment of the safety, health and environmental impact of the new design (with the aim of improving safety, and reducing the environmental impact); and

· Review the economics of the new structures from procurement to disposal (taking into account, foundations, access requirements, construction time, maintenance and lifetime of the new structure).

  • Produce a literature review of available products
  • Create technical specifications for assessing 132kV alternative poles
  • Identify all the costs and benefits of available composite, laminated and modular pole alternatives
  • Develop a more accurate cost benefit analysis tool
  • Define an appropriate testing methodology for products
  • Estimate and schedule requirements for future testing and development
The project will seek to improve the variability of currently understood costs and benefits of available composite, laminated and modular pole alternatives.To identify the appropriate applications for available composite, laminated and modular pole alternatives in the UK.To identify the costs and benefits of available composite, laminated and modular pole alternatives and develop a detailed cost benefit analysis case which will give a clear recommendation for their deployment across the SHETL area.
