What is ESB Networks?
The company that operates Ireland's electricity distribution grid and manages microgeneration connections.
Quick Answer
To connect a solar PV system to the Irish grid, your installer submits an NC6 form to ESB Networks on your behalf. ESB Networks then issues approval and, if needed, upgrades your meter to a smart meter that records both import and export. Processing times are typically 2–6 weeks. There is no charge for standard microgeneration connections under 6kWp.
