Electricity Generation Installers

Installers of Solar PV, Wind generation or Battery Storage are required to notify the local network owning I/DNO (Independent/Distribution Network Operator), to apply for their connection. 

The I/DNO is required to respond within 65 days provided all application information and supporting data has been submitted to them. This process helps network operators ensure that the network can accommodate the export capacity and can continue to operate in a safe and reliable manner.

The generation connection process has been developed by the Energy Networks Association (ENA), and is the process and documentation to be used to notify the local network owner. 

The ENA website also includes guidance for generation operators on compliancy for operating generation in parallel with the network. We encourage all installers to talk to us and use the notification/application process as appropriate.

Embedded Capacity Register

The embedded capacity register has been developed to provide data on DER (Distributed Energy Resources) on the ENC (Electricity Network Company’s) and IPN’s (Independent Power Networks Limited’s) networks.

The register provides information on generation and storage resources greater or equal to 1MW, connected or accepted to connect, to ENC’s and IPN’s networks. 

This register will be updated on a monthly basis and is available for download within the ‘Useful Literature’ section.


This embedded capacity register has been developed in line with our requirements under The Distribution Connection and Use of System Agreement (DCUSA). Whilst all reasonable endeavours are used to ensure the accuracy of data published, no responsibility or liability is accepted by Eclipse Power Networks Ltd for the accuracy or completeness of the content or any loss which may arise from reliance on the capacity register and related information.
