Frequently Asked Questions on Buying a Generator in Ireland
How much does it cost when buying a generator in Ireland?
Quality standby diesel generators in Ireland typically range from €5,000 to €9,000 for residential 15–25 kVA units, €10,000 to €18,000 for mid-range 40–100 kVA commercial/farm sets, and higher for large containerized industrial systems, excluding ATS switchgear and electrical installation.
Do I need ESB permission to install a generator in Ireland?
While you do not need permission to own a generator, any standby generator connected to a building’s distribution board MUST be installed with a break-before-make 4-pole changeover switch adhering to IS 10101:2020 standards to prevent back-feeding into ESB Networks lines.
Where should a diesel generator be situated on site?
Standby generators must be positioned outdoors on a reinforced concrete plinth, situated away from open windows and ventilation air intakes to avoid exhaust fume ingress, with adequate perimeter clearance for maintenance access.
