"The project went exceptionally well. The downtime was hardly noticeable with little disruption while other work was carried out. The CHP is the heart of the system and provides a major contribution to our electricity usage. I would strongly recommend this installation to any nursing home thinking of upgrading - It's a no brainer."

A member from Gas Networks Ireland will carry out a site survey and offer advice on where to best to locate the gas meter. There are usually a number of locations that are suitable and care needs to be taken to ensure that the chosen location is compliant with all relevant safety standards.


A road opening license is legal permission given by the local council for public roads, green areas and footpaths to be excavated.  Each local council has their own timelines and conditions. Gas Networks Ireland has agreements in place with all councils where there is gas located and therefore has foresight into existing timelines and conditions.

If you are already using another fuel for your business, you should check your bills over the last 12 months to get a view on how much fuel was used in a year.  If nothing in your business is changing, then this figure can be used as your estimated annual consumption (converted into kWh).  For the Maximum Hourly Load (MHL), it is recommended that you ask your chosen Registered Gas Installer (RGI) or Competent Installer/plumber as they will be able to offer technical information relating to the expected hourly usage of your equipment.  Our technical representative can also review your usage and offer advice to confirm.

SPC stands for Supply Point Capacity.  For Small and Medium Business users, Gas Networks Ireland will calculate the SPC for new connections based on your Estimated Annual Consumption (EAC), measured in kWh.  Your gas supplier is required to reserve space in the natural gas network to guarantee a secure supply of gas. The amount of space reserved by your gas supplier is referred to as the Supply Point Capacity. GNI charge all natural gas suppliers for reserving this space. Your gas supplier then passes this charge onto you in the form of standing charges.
