Connecting Synchronised Generators larger than 6kW single phase or 11kW three phase
This section explains how to connect generators larger than 6kW single phase or 11kW three phase that may be exporting electricity to the Electricity Network for sale or supply.
Note: For connections made after September 2018 some Distribution Code conditions may change, arising from the need to be aligned with European Network Codes. For more information on this see our European Network Codes page.
Enduring Connection Policy Stage 2 (ECP-2)
On 10th June 2020, the Commission of Regulation for Utilities (CRU) published its decision on the Enduring Connection Policy Stage 2 (ECP-2).
The ECP-2.1 application window is now closed. The application window for ECP-2.2 is scheduled to open to all generating and storage technologies (greater than 0.5MW) from 1st September 2021 with a closing date of 30th September 2021. Please refer to the CRU website: Enduring Connection Policy Stage 2 (ECP-2) CRU/20/060 for further information.
All generating and storage technologies (less than or equal to 0.5MW) can apply on an ongoing basis, please see section 4.5 of the ECP-2 ruleset. The current Generator Application Forms NC5 Form | Download PDF 603 KB and NC5A Form | Download PDF 527 KB are available for download from the ESB Networks website for all applications.
EirGrid and ESB Networks (the System Operators or “SOs”) have taken this opportunity to review and publish an updated joint ruleset of how applications are assigned to nodes for offer processing. This update is based on feedback received from industry and the SOs’ own processing work since the original node assignment ruleset was published in 2009. The ruleset will remain under review, particularly as we complete annual batches, and updates will be published as required. Link to the ECP-2 Node Assignment Rules can be found here.
Generator Standard Charges
The CRU published a decision paper (CRU/21/035) on ESB Networks 2020 proposals for changes to Generator Standard Charges (GSCs). The new 2021 ESB Networks “Standard Prices for Generator Connections 2021” document is published alongside this decision (CRU/21/035a). See link to CRU Decision here.
This decision is the outcome of a three year review process for these charges including two consultations and a number of independent advisor reviews. The GSCs approved by this decision will be used by ESB Networks from this point forward and, allowing for inflation, will apply until at least after Enduring Connection Policy – Stage 2, Batch 3 (ECP-2.3) offers.
For any other ECP-2 queries not covered on our website please refer to Enduring Connection Policy Stage 2 (ECP-2) CRU/20/060. For all other queries please email DSOgenerators@esb.ie.
