Your guide to microgeneration in Ireland

Energy microgeneration for homes

Updated January 2025

What is microgeneration?

Microgeneration refers to the small-scale generation of electricity by households or small businesses to meet their own needs, in addition to their existing electricity supply. This is known as “self-consumption”. 

The most common form of microgeneration and one you may be familiar with is solar panels, however, there are different types of microgeneration technologies available.

Types of microgeneration technologies

Microgeneration involves installing a small generator powered by a renewable source such as wind, solar or hydropower, and connecting this to the electricity network.

Benefits of microgeneration

You can now sign up for a microgeneration plan by signing into your online account. Sign in and choose to receive a payment for exporting your excess energy to the grid. 

Terms and conditions apply

Export and earn with Bord Gáis Energy 

Customers of Bord Gáis Energy are now entitled to a payment for any electricity exported to the national grid.

We are offering our customers, both business and homeowners, 18.5 cent per kWh for any excess electricity that they are microgenerating and exporting to the electricity grid under our Microgen Export Plan. This rate will be offered to both metered and eligible deemed* customers.

Microgeneration payments

• To receive a payment, you’ll need to agree to our Microgen Export Plan T&Cs
• If you were a Bord Gáis Energy customer on February 15th 2022 (date of legislation) and microgenerating at that time, your payment will be back-dated.
• If you joined us after February 15th 2022, payments will be back-dated to when you became an eligible customer. 
• All payments will be based on the data provided to us by ESB Networks.  
• Once you’ve exported for at least 3 months, payments will be made 4 times per year as a credit to your electricity bill. We started making our first payments from March 2023.
• If you’re eligible for a smart meter, you’ll need to have one installed to qualify for a payment.

* Deemed customers are customers who are not eligible under the National Smart Metering Program to have a smart meter installed.  In this case, your export amount will be calculated (deemed) using a pre-determined formula.

Bord Gáis Energy are supporting our customers take-up of microgeneration technologies and move towards net zero. 

Who is eligible for the scheme?

• To qualify for an export payment with Bord Gáis Energy, you must have us as your energy supplier. Go to our plans page to see our available offers.
• You must have a microgenerator installed (i.e. solar PV, micro-wind, micro-hydro or renewable micro-CHP).
• You must have notified ESBN of your microgeneration connection to the grid (via an NC6 form or equivalent). If you are not sure whether your installer has completed this form, contact ESB Networks to confirm. 
• If you're eligible to have a smart meter installed during this phase of the rollout, then you will need a smart meter to be paid for your export. Where customers are eligible to have a smart meter installed, ESB Networks will endeavour to install a smart meter within four months of a valid NC6 form being processed by ESB Networks. 
• If you're not eligible to have a smart meter installed during this phase, then you'll be paid based on a deemed export calculation.

_{*MEC stands for Maximum Export Capacity. This refers to the capacity (measured in kW) of your microgeneration equipment.}

_{** 24-hour meter customers (also known as MCC01 meter) are eligible for microgeneration payments if they have a smart meter. 3 phase MCC01 meters are not yet eligible for smart meters and qualify for deemed payments.  Day/night meters(MCC02) are now included in the smart meter roll-out since September 2023.  If your micro-generator installation was approved after 11 September 2023, you will need a smart meter to qualify for a microgeneration payment.}

_{***'Deemed' relates to your Deemed Export Quantity. This is an estimation based on a formula, of your exported electricity in kWh. Your deemed export quantity is sent to us by ESB Networks in situations where metered export data is not available.}

How to invest in microgeneration

✔ Get an assessment of the suitability of your property

✔ Apply for a grant from Sustainable Energy Authority of Ireland (SEAI)

✔ Install solar PV or other microgeneration technology

✔ Notify ESBN via an NC6 form (or equivalent)

✔ Secure an export tariff with Bord Gáis Energy. Eligible customers can sign in now and choose to receive a payment for exporting surplus energy to the grid. 

What is the Micro-Generation Support Scheme?

As part of its Climate Action Plan, the Irish government announced the launch of the Micro-Generation Support Scheme, which aims to incentivise homes, businesses, farms, and communities in Ireland to reduce their carbon footprint by using renewable generation technologies to produce their own clean energy. 

A range of grants and supports were made available to boost Ireland's energy transition and encourage investment in micro-generators such as solar installations, micro-wind and micro-hydro power sources for renewable energy. 

For further information on the grant scheme visit the SEAI's grant information hub. You can find more details on the government support scheme on gov.ie.

Recent changes to smart meter eligibility

What’s changing?

From September 2023, if you have any of the following meters, you’ll be eligible to receive a smart meter replacement:

• Day/night meters will be replaced with smart day/night meters.  Day/night simply means you pay different unit rates for daytime (8am to 11pm) and night-time (11pm to 8am).
• 3 phase meters (24-hour only) will be replaced with smart 24-hour meters.  3 phase meters have 3 main fuses instead of one fuse in single-phase installations.
• Night storage heating customers who haven’t used their night storage heating register for over two years will be eligible for a smart meter exchange.  Night storage customers pay a 24-hour unit rate for electricity, apart from any storage heating used overnight, which is charged at a lower rate.  One thing to note is that for night storage heating, there’s a standing charge applied to both the 24-hour electricity and the night storage electricity. If you choose to switch to a smart meter, you’ll be on a 24-hour meter and will only pay one standing charge.
