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. If you’re microgenerating, you can sell your excess electricity back to the grid.  

Microgeneration involves installing a small generator powered by a renewable source such as solar, wind or hydropower and connecting it to the electricity network. Microgeneration technologies in scope for the Clean Energy Guarantee (CEG) payment include Solar Photo-Voltaic (PV), Micro-Wind, Micro-Hydro and Renewable Micro-CHP (Combined Heat and Power).  

If you wish to connect a microgenerator to the network, you should notify ESB Networks using an NC6 or equivalent form. The form and details are available on ESB Networks website.  

Once your application has been processed, ESBN will notify your supplier of your Maximum Export Capacity (MEC). Your MEC is the maximum output of electricity that your generator can produce. Microgeneration installations up to 50kW can qualify for a microgen payment. Once you have your MEC, you can sign up for our microgen export plan. Click here to check if you're eligible.

Please note: if your power is at powered off status you cannot use your microgenerator to export electricity. Microgenerators have protective devices which, for safety purposes, switch the generator off if the electricity supply is off or de-energised.
