Engineering Overview

ENA's engineers are responsible for managing the annual work programme agreed, on behalf of member companies, by the Electricity Networks and Futures Group (ENFG). These activities provide key support for member companies and help to promote the introduction of new initiatives through joint working. Some examples include:

  • Development of the Distributed Generation Connection Guides.

  • Flooding resilience in conjunction with Ofgem, BEIS, the Environment Agency and the Met Office.

  • Climate Change Adaptation Reporting in conjunction with BEIS, Ofgem and Defra.

  • Distribution Network Operator (DNO) / Independent DNO Technical Interface.

The engineering team publishes and maintains the wide range of ENA engineering documents. Some of these documents are annexed to the Distribution Code so in these cases governance of the documents rests with the Distribution Code Review Panel (DCRP).

Over 400 publications are available to buy through the ENA engineering document catalogue and there also a number of free engineering documents. These engineering documents support important initiatives including the move to low-carbon networks through the connection of distributed generation. They will be further expanded to assist the development of smart grids.
