Microgeneration

What is Microgeneration?

Microgeneration is the general term used to refer to small-scale generation of electricity from renewable technologies including but not limited to solar PV and wind power. This type of generation allows you to produce electricity in your home environment, as an alternative or supplement to electricity from the national energy grid.

As well as meeting some, or all, of your electricity needs, as of early 2022 microgeneration took a step forward with the introduction of the Clean Export Guarantee (CEG). This means that while the majority of the energy produced will be used to power your home, from time to time, when there is surplus electricity from your microgeneration you can export this to the grid and receive a payment for it. By reducing your usage offtake and increasing the volume of renewable energy supplied to the grid you can actively contribute to a greener, cleaner Ireland while lowering your own energy bills.

A great deal for you and a great deal for the environment.

How do I get Microgeneration installed?

If you’re interested in installing microgeneration or solar PV in your home, please visit our partners Activ8 Solar Energies.

What is the Clean Export Guarantee (CEG)?

The clean export Guarantee (CEG) means that while the majority of the energy produced will be used to power your home, from time to time, when there is surplus electricity from your microgeneration you can export this to the grid and receive a payment for it.

Am I eligible?

Whether you are eligible for the scheme depends on a number of factors. Please check your meter type and the criteria set out below.

For homes with a smart meter already installed.

  • You must complete an NC6 form with ESBN

For homes with a 24hr (MCC01, MCC12, MCC16) meter currently in place.

  • You must have a smart meter installed by ESBN
  • You must complete an NC6 form with ESBN

For homes with other meter types (excluding 24hr meters & smart meters)

  • ESBN will provide a deemed export (detailed below)
  • You must complete an NC6 form with ESBN

Please note, you won’t be entitled to export payment related to microgeneration until the eligibility requirement have been met.

What is an NC6 form?

To be eligible for payments, ESB Networks first need to be notified of your microgeneration install so they can start recording your export to the grid. This is done by completing an NC6 form. This would have been completed with your technician at the time of installation.

However, if you’re not sure if the NC6 form has previously been submitted, please contact ESB Networks. If an NC6 form has not been submitted, please contact your installation company to complete this and return to ESB Networks as soon as possible.

For a step-by-step guide on Microgen connection, please contact ESB Networks.

How much will I earn?

Export payments will be made based upon the surplus energy generated at your home. If you have a smart meter the actual export (metered export) to the grid will be measured and you’ll be paid accordingly. For more information on smart meters please visit our Smart Meter section. All other meters will estimate the export value (deemed export) and you’ll be paid accordingly.

* If you have refused or refuse the installation of a smart meter, then you will not be eligible for a deemed export profile (see below). If you have refused or refuse the installation of a smart meter and now want to avail of the scheme, you must request the installation of a smart meter. This can be done through your supplier or ESBN.

What is the rate per kWh for the Clean Export Guarantee (CEG) Microgeneration?

As of June 2022, we are offering a rate of 14cent per kWh produced.

Do I get tax back / need to advise of income for taxation?

Your CEG payment will be based on a per kWh basis at 14 cent per unit. There is no published guidance for customers in relation to the VAT treatment of electricity exported to the grid by customers.

If customers have any queries in relation to their VAT compliance obligations in relation to electricity exported, they should contact the Revenue Commissioners or CRU.

What is the difference between metered export and deemed export?

The export type is dependent on the meter you have at home. For example, a smart meter has a metered export type, meaning the actual energy generated is measured and payment is made accordingly. All other meters have what’s called a deemed export. This export type assumes that the majority of the electricity generated is being used in the home.

This calculation has been decided by the Commission for Regulation of Utilities (CRU) with government oversight. There is no mechanism to change this amount except for the installation of a smart meter to record actual consumption and therefore the surplus generated. Your energy provider has no role in determining this export value. 

How is deemed export calculated?

The calculation of the deemed export is based on the following factors and has been set by the Commission for Regulation of Utilities (CRU).

The following formula determines the Deemed Export Quantity:

Deemed Export Quantity= MEC x Capacity Factor x Export Factor x Provision Interval

MEC – This will come from the NC6 form which the customer is required to submit to ESBN.
Capacity Factor – This is based on a calculation from the CRU and is set at 9.7%
Export Factor – This is based on a calculation from the CRU and is set at 35%
Provisional interval – This is a calculation used for solar installations that takes account of how Microgeneration works in practice during the day and from season to season.

It’s important to note that you will need a smart meter to be eligible for actual metered exports.

When can I expect to receive payment?

Credit customers

From August 2022 we'll start to credit your SSE Airtricity account with your export payment. This will then appear on your following statement.

What happens if I have Microgeneration installed at my property, but don’t have a smart meter installed?

For customers that are not yet eligible for a smart meter:

  • ESBN will provide a deemed (estimated) export
  • You must complete an NC6 form with ESBN

Please note, if a customer has refused or refuses the installation of a smart meter, then they will not be eligible for a deemed export profile. If a customer has refused or refuses the installation of a smart meter and now wants to avail of the scheme, they must request the installation of a smart meter, this can be done through their supplier or ESBN.
