Residential gas consumption increased by 13.5% in 2018

go to full release

Power plants accounted for 61% of total networked gas consumption in 2018 compared with 24% by the non-residential sector and 14% by the residential sector (see Headline Table and Figure 1). This pattern was broadly similar in 2011 to 2017. Total consumption was 57,129 gigawatt hours in 2018, an increase of 4.4% over 2017 consumption, and the highest consumption over the 2011-2018 period. The increase in consumption in 2018 was comprised of a 1.6% increase in consumption by power plants, a 6.9% increase by the non-residential sector and a 13.5% increase by the residential sector (see Tables 2B, 2C, and 2D).

There is strong seasonal variation in networked gas consumption by households. The January to March quarter has by far the highest consumption, at 46% of the annual total in 2018. In contrast July to September accounted for only 5% of total residential consumption in 2018 (see Table 2D and Figure 2). Seasonal variation was less evident in other sectors with the third quarter of 2018 accounting for 28% of total usage by power plants and for 19% in the non-residential sector (see Tables 2B and 2C).

Table 3B shows residential consumption by county. Dublin postal districts accounted for 45% of total residential consumption in 2018, followed by Dublin County which accounted for a further 16% and Cork at 11%. Three counties (Donegal, Leitrim, and Sligo) are not connected to the gas network, while Longford has no residential connections.

Table 4B shows the corresponding table for individual Dublin postal districts. Dublin 15, with 387 GWh, had the highest residential consumption in 2018 followed by Dublin 24 with 259 GWh. The postal districts with the lowest consumption were Dublin 2 (32 GWh) and Dublin 1 (35 GWh).

Table 5C shows the median consumption figures at meter level for the residential sector at Dublin postal district level. Dublin 1 at 6,876 kilowatt hours, Dublin 2 at 7,007 kWh, and Dublin 8 at 8,418 kWh had the lowest median consumption figures in 2018. These areas were all well below the overall median consumption of 11,193 kWh for all households in the Dublin postal district areas. In contrast Dublin 6W had the highest median consumption (13,772 kWh), closely followed by Dublin 6 (13,182 kWh).

Table 5B and Figure 3 show the median residential consumption at county level. Figures for Kerry, Roscommon and Wexford are based on low numbers of meters (see Table 6B). For other counties, Mayo at 7,677 kWh in 2018 had the lowest median consumption, while Dublin County had the highest median consumption at 11,603 kWh. Table 5D shows the quarterly median consumption figures for 2018 at county level. 

Tables 6A and 6B show the number of gas meters by county. Dublin postal district areas accounted for 43% of both non-residential and residential meters. The number of non-residential meters has increased by 9.7% from 26,472 in 2011 to 29,039 in 2018. The number of residential meters has increased by 7% from 632,986 in 2011 to 677,611 in 2018.

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. 

Coverage

The data cover all consumers connected to the natural gas network. This includes power plants, non-residential, and residential customers. Three counties (Donegal, Leitrim, and Sligo) had no meter connections. Longford had no residential 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 677,600 residential gas meters in 2018. 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 Networks Ireland reports and with the Sustainable Energy Authority of Ireland energy balances.

Revisions

Data for all years are subject to revision.

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 2011-2018 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 is 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. Their classification is partly based on the consumption figure. The CSO made a small number of adjustments to recode some meters in a consistent way for all years. 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.
