Background:

In order to support the Irish Government's National Climate Action Plan, ESB Networks needs to develop standard options to facilitate faster and optimised connection options for renewable and customer connections to our network.

As part of the Irish Government’s Climate Action Plan 2019, there are several targets within the electricity sector that must be met by 2030 including “the development of up to 1.5 GW of grid scale solar energy, an increase in onshore wind capacity of up to 8.2 GW”. As the generation market in Ireland is moving towards low carbon renewables, there has been a marked increase in smaller Independent Power Providers (IPPs) looking for connections to the electricity network. A significant number of solar connections are expected to come on-stream from 2021. As an IPP could have a solar farm constructed in a much shorter timeframe than, for example, a windfarm development, ESB Networks will have to deliver a Medium Voltage (MV - 20 or 10 kV) Embedded Generation Interface Protection (EGIP) Substation connection in a considerably shorter timeframe than our current standard.

The aim of this project is to support the renewable generation industry by facilitating a faster connection of embedded generation to the Distribution System. ESB Networks has developed an MV EGIP Standard Module solution that will allow for 1 to 20 MVA connection to ESB Networks MV System (Note: Generation Connection load capacity is still subject to system voltage present at connection node, local system capacity and possible system reinforcement requirements upstream of connection). This solution will remove the requirement to build a free standing MV block building, which requires significant on-site construction, with a module that can be factory built and then deployed to site thus allowing for faster connection to the system.

Consultation Question:

Introducing an alternative connection option for MV customers requires significant stakeholder consultation, as such we would like to get feedback from all stakeholders and welcome any comments interested stakeholders may have on this proposal. 

Next Steps:

The consultation period will close at 5pm on Friday 15th January 2021, please send your feedback to innovationfeedback@esbnetworks.ie

Please Note: To facilitate stakeholder feedback, in conjunction with the consultation document, we will be hosting a public webinar on Friday 11th December (12.00pm – 1.00pm), and a showcase of a standard module build at ESB Networks’ National Training Centre in Portlaoise, Co. Laois in Q1 2021 (further details to follow).

To register your interest in attending our webinar event and/or showcase event, please email innovationfeedback@esbnetworks.ie, indicating which event (webinar and/or showcase) you wish to attend.

Expressions of interest to attend can be included in your feedback on the consultation document.

In light of the COVID-19 restrictions and safety procedures, attendance at the showcase event at ESB Networks’ National Training Centre in Portlaoise, Co. Laois, in Q1 2021 may be limited.

In order to meet the targets set out in the National Climate Action Plan, ESB Networks is developing standard module connection options to facilitate the faster connection of customers deploying low-carbon technology. ESB Networks is looking for stakeholder feedback on our proposed alternative MV connection options for electric vehicle charging sites in urban service station locations.

The System Operators have undertaken to update the node assignments list from time to time to confirm any changes to the Gate 3 tables originally published on the 19th January 2009. Changes are marked in yellow in the document and a footnote is included explaining the high level reason for the change.
