Networked Gas Consumption by Sector (GWh)
go to full release

There is strong seasonal variation in networked gas consumption by households. The January to March quarter had by far the highest consumption varying from 53% of total residential usage in 2011 to 43% in 2016. In contrast July to September accounted for only 6% of total residential consumption in 2016 (see Headline Table and Table 2D). Consumption was less seasonal in other sectors with the third quarter of 2016 accounting for 27% of total usage by power plants and for 20% in the non-residential sector (see Tables 2B and 2C).

Power plants accounted for 62% of total networked gas consumption in 2016 compared with 24% by the non-residential sector and 13% by the residential sector (see Table 1 and Figure 1). This pattern was broadly similar in 2011 to 2015.

Table 3B shows residential consumption by county. Dublin postal districts accounted for 46% of total residential consumption in 2016, followed by Dublin county which accounted for a further 16% and Cork at 11%. Five counties (Donegal, Kerry, Leitrim, Longford, and Sligo) are not connected to the gas network. 

Table 4B shows the corresponding table for individual Dublin postal districts. Dublin 15, at 353 Gigawatt hours, had the highest residential consumption in 2016 followed by Dublin 24 with 220 GWh.

Table 5C shows the median consumption figures for the residential sector at Dublin postal district level. Dublin 1 at 6,278 kilowatt hours and Dublin 2 at 6,244 kWh had the lowest median consumption figures in 2016. Dublin 8 at 7,476 kWh and Dublin 10 at 8,718 kWh had the next lowest median levels of usage, and they were both well below the median consumption of 10,377 kWh for all households in the Dublin postal district areas. In contrast Dublin 14 had the highest median consumption at 12,822 kWh.

Table 5B and Figure 3 show the median residential consumption at county level. Mayo at 6,686 kWh in 2016 had the lowest level of consumption. Waterford at 7,685 kWh was the next lowest. Meath at 10,910 kWh had the highest median consumption figure. Table 5D shows the quarterly median consumption figures for 2016 at county level. The median consumption figure in January to March in the Dublin Postal District areas was ten times higher than the median for the July to September quarter. The ratio was much lower in Galway (6), Mayo (6) and Monaghan (5). This may indicate that a higher proportion of other fuels are being used for heating in these counties.

Tables 6A and 6B show the number of gas meters by county. Dublin postal district areas accounted for 43% of non-residential meters and for 44% of residential meters. The number of non-residential meters has increased from 26,482 in 2011 to 28,551 in 2016. The number of residential meters has increased from 632,978 in 2011 to 659,722 in 2016.

Background Notes

Networked Gas Consumption

Introduction

This release contains consumption data from Gas Networks Ireland on all connections to the mains gas network.

Consumption units

The data are gross calorific values expressed in kilowatt hours (kWh) or Gigawatt hours (GWh). A kilowatt hour is a unit of energy equivalent to one kilowatt of power sustained over an hour. A Gigawatt hour is equivalent to one million kWh. Kilowatt hours are used for presenting median figures and gigawatt hours for presenting aggregates.

County

The CSO extracted the county and Dublin postal district from the postal address provided by Gas Networks Ireland. Additional work was required to identify a county for the largest non-residential customers as these were provided in a separate monthly file that did not contain the customer's address. There was a very small number of dwellings connected to the gas network in Wexford in 2016. The figures for Wexford should not be regarded as covering the full year. Accordingly we have excluded Wexford from Figure 3.

Coverage

The data cover all consumers connected to the natural gas network. This includes power plants, non-residential, and residential customers. Five counties (Donegal, Kerry, Leitrim, Longford, and Sligo) had no meter connections. The 2016 Census of Population showed that there were around two million households in Ireland of which 1.7 million were occupied. This release showed that there were around 660,000 residential gas meters in 2016. The release contains a map showing the location of the residential meters using the coordinates provided by Gas Networks Ireland (see Figure 4).

Data quality

The meter readings data were converted to monthly and quarterly consumption estimates by Gas Networks Ireland. Meter readings can be actual or estimated. In some cases an estimated reading that was too high resulted in a low or negative reading for a subsequent period, i.e. no attempt was made to adjust the earlier over or under estimate. The data file provided to the CSO did not provide information on whether the consumption in a period was based on an estimated reading. The results are broadly consistent with Gas Network Ireland reports and with the Sustainable Energy Authority of Ireland energy balances.

Data source

The CSO received the administrative microdata from Gas Networks Ireland under Section 30 of the Statistics Act, 1993. The microdata contain quarterly consumption data for residential and smaller non-residential customers and monthly data for larger users. The CSO received data for 2011-2016 for all customers and for 2006 for residential and smaller non-residential customers.

Median

The median can be regarded as typical usage as it is not influenced by outliers in the same way that the mean or average is. The median for a year is calculated independently of the quarterly medians, e.g. in Table 5A.

Release frequency

This release will be published on an annual basis.

Sector

The data have been classified into three sectors: power plants; non-residential; and residential. Gas Networks Ireland classified the data as residential or non-residential. The CSO classified a small number of customers as power plants. 

There are around 29,000 non-residential customers. The CSO will try to add NACE codes to these records, as NACE would provide a more detailed analysis of the non-domestic customers.
