In December 2012, the Electrical Safety Committee (ESC) published an updated Blue Book.  The Blue Book applies to all persons working on, near or in the vicinity of HV apparatus that is capable of being energised, (including transmission and HV customers).

The Distribution Network Operators have different requirements to those companies and the Green Book is how we meet those requirements whilst demonstrating compliance to the Blue Book.  As has been advised previously, the 2006 Green Book has been under review since late 2011. 

That update is now complete and available online with other helpful material including:

  • Training slides
  • A map between the 2006 and 2013 Green Books
  • A summary of the public feedback received in July 2013

This material and further information regarding the 2013 Green Book can be found at the Green Book Committee webpage at the following link:
