The Industry sector accounted for 54% of total non-domestic energy consumption in 2015 in terms of kilotonnes of oil equivalent (ktoe). The energy products used by industry have a lower relative cost than those used by the Services sector. Hence the proportion of purchase costs accounted for by the industry sector was 40% in 2015 compared with 60% of fuel purchase costs being paid for by the Services sector. The total consumption by industry and services increased by 2.8% in quantity terms (ktoe) in 2015 but fell by 8.1% in cost terms (see Headline Table and Tables 1A and 1B).

The mix of energy products used by Irish enterprises in 2015 is given in Figure 1. In terms of ktoe, natural gas accounted for 30% of the total kilotonnes of oil equivalent with aviation fuels accounting for a further 23%. Solid fuels comprised another 15% and electricity a further 13%. The use of energy from renewables and from waste increased from 217 ktoe in 2009 to 334 ktoe in 2015 or by 54% over the six years (see Table 2A).

In monetary terms the proportion of total fuel purchase costs accounted for by each energy product was quite different than the ktoe distribution (see Tables 2A and 2C). Electricity accounted for 33% of total costs while natural gas comprised 20%. This turnaround is partly accounted for by electricity being used for final energy consumption whereas a substantial proportion of natural gas is used for intermediate consumption to make electricity (see Table 4A). Road transport fuels similarly accounted for a much smaller proportion of total ktoe in 2015 (9%) than of total cost (17%).

This release is based on the National Accounts residence principle. This means that energy used abroad by enterprises resident in Ireland is included. Energy used in Ireland by foreign resident enterprises is not included. See Background Notes for more information.

Tables 3A and 3B show the distribution of ktoe and purchase costs by NACE sector. The Electricity and Gas NACE sector accounted for 31% of ktoe but for only 18% of costs. The Transport NACE sector used 27% of ktoe and 26% of costs (international flights by Irish airlines accounted for a large proportion of this activity).

Tables 4A to 4G show the quantity of fuels used by each NACE sector in each year. The Electricity and Gas NACE sector used 94% of Solid Fuels ktoe in 2015. The Manufacturing NACE sector used 65% of Renewable Energy in 2015 and the Transport NACE sector used 42% of Road Transport ktoe (see Table 4A). The corresponding data for purchase costs by each NACE sector in each year is shown in Tables 5A to 5G.

Table 6A shows the proportion of ktoe accounted for by the Emissions Trading Scheme sector. In 2010 46% of ktoe was used by ETS installations. This proportion decreased to 42% in 2015. The corresponding data for purchase costs is shown in Table 6C. ETS companies accounted for 28% of total fuel costs in 2009. This rate dropped to 24% in 2015.

Table 7A shows the distribution of energy consumption by county. In 2015 Dublin consumed 63% of the total kilotonnes of oil equivalent followed by Cork with 8% and Limerick with 6%. The corresponding shares of total energy costs are given in Figure 4 and Table 7B.

Background Notes

Introduction

The Business Energy Use (BEU) survey was first undertaken in 2009 and it has been conducted on an annual basis since then. The primary purpose of the survey is to provide estimates of the quantities and costs of energy products used by enterprises in the Industry and Services sectors to operate their businesses. The CSO Structural Business Statistics Division is responsible for selecting the sample, obtaining returns, and conducting initial editing. In 2013 the CSO Environment Section was assigned responsibility for the questionnaire design, detailed processing, integration of other data sources, weighting, and publication.

Legal basis

The BEU survey is a compulsory survey conducted under the Statistics (Business Energy Use Survey) Order 2016 (S.I. No. 116 of 2016) made under the Statistics Act, 1993.

Coverage

The sampling unit is an enterprise. The samples for the 2009 to 2016 surveys were selected from enterprises with 10 or more employees on the CSO Business Register. In 2017 the sample was broadened to include enterprises with 3-9 employees to give a better representation of smaller companies in the weighting. The annual sample is around 5,000 with a response rate of around 60%. A smaller sample was used in 2010 when only Industry enterprises were covered. In 2011, only Services enterprises were included in the sample.

Energy use by enterprises and family farms in NACE Divisions 01-03 (Agriculture, forestry and fishing) are not included in the results. Energy use by households is also excluded.

Both quantity and cost data are collected. Value Added Tax is excluded from the purchase cost.

National Accounts Residence Principle

This release is based on the National Accounts residence principle. This means that energy used abroad by enterprises resident in Ireland is included. Energy used in Ireland by foreign resident enterprises is not included. The territory principle, which is used in Energy Balances and in the Greenhouse Gas Emission inventory, does not include energy used abroad by enterprises resident in Ireland but includes energy used in Ireland by enterprises that are not resident in Ireland e.g. road hauliers. This methodological difference is particularly important for aviation transport fuels.

Transformation fuels

The use of natural gas to produce electricity was collected as a separate item in the questionnaire. The use of other fuels such as coal and peat were recorded under their own categories and the transformation use of those fuels was not collected in the BEU questionnaire. In some cases it can be inferred e.g. purchases of coal by enterprises producing electricity.

Weighting

The CSO’s Business Register provided the frame from which the annual BEU survey sample was selected. The register was used to weight sample data to the population by calculating factors based on the number of employees in the sample and in the register at NACE Rev.2 Division level. Some non-typical returns were assigned a weight of one to prevent them having an influence on other returns.

Questionnaire

The BEU e-Form is available on the CSO’s website at: https://eforms.cso.ie/BEEU.html

The form has changed since the survey commenced in 2009. A specific question on road transport fuels was introduced in the 2013 survey.

The scope of the survey includes purchases of transformation fuels, e.g. to produce electricity, as well as final energy consumption uses.

The 2017 survey form collected data on the following categories:

• Electricity purchased
• Electricity self-generated
• Natural gas
• Petroleum products
• Road transport energy products
• Coal
• Renewable energy and Energy from waste
• Other energy
• Heating system / Air conditioning

A pilot data collection for 2018 data containing explicit questionnaire sections for aviation, marine, and rail fuels will be conducted in 2019.

Additional Data Sources

The survey returns were boosted with the inclusion of data from non-CSO administrative data sources and CSO structural business surveys. This was done to: maximise the use of existing data; to increase consistency with air emissions and energy balances data; and to increase the effective sample so that the survey could be weighted at NACE Rev.2 Division level. The additional data sources comprise of a mixture of enterprise and local kind-of-activity unit and some of the data sources only collect quantity data while some only collect data on fuel purchase costs. The CSO used average costs at NACE sector level to overcome these weaknesses.

To integrate the administrative data with the survey returns, the CSO matched the administrative registers with the CSO Business Register to obtain information on NACE sector and employment and to ensure that no company was included more than once from the different data sources. In some cases, a survey respondent was also included in an administrative data source. In these cases, the CSO compared and combined the responses as necessary e.g. the different data sources collected different energy product categories.

The CSO obtained access to the administrative microdata under the Statistics Act, 1993 which allows such data to be used by the CSO for statistical purposes.

- Emissions Trading Scheme

The Environmental Protection Agency collects quantity data from licenced installations on an annual basis. The data include fuel quantities only. The CSO used a mixture of monetary data from other data sources (e.g. the ETS enterprise may have made a Business Energy Use survey return) and unit prices to estimate corresponding fuel costs. There were returns for around 360 installations in 2015 and these represented around 75 enterprises after being matched with the CSO Business Register i.e. ETS installations could belong to the same enterprise. The ETS scheme comprises large industrial users and hence accounts for a very large proportion of energy consumption relative to the number of returns. Some energy products such as electricity were not collected as part of the ETS return but it was extracted in some cases by the CSO from EPA Annual Environmental Reports or from other data sources.

Users requiring definitive ETS figures should contact the EPA.

- Large Industry Energy Network

The Sustainable Energy Authority of Ireland administers the LIEN scheme. In 2015 there were around 150 LIEN returns. These returns typically relate to large energy users. Both quantity and cost data are collected. While the CSO examined all LIEN data, in some cases we used the return from the BEU if the enterprise was included in both data sources.

Users requiring definitive LIEN figures should contact the SEAI.

- Public Sector Energy Programme

The Sustainable Energy Authority of Ireland administers the energy monitoring and reporting scheme (M&R) under the PSEP. The returns comprise a mixture of utility meter data and directly collected data. The coverage of the scheme has broadened considerably in recent years to include more schools. PSEP returns were only included by the CSO if the public sector body had validated their meter numbers and submitted a return to SEAI for non-metered fuels. This large number of returns has resulted in a very high coverage of public sector energy use in the survey. Only quantity data were collected. The CSO used unit prices to estimate costs.

Users requiring definitive M&R figures should contact the SEAI.

- Annual Services Inquiry

The ASI is an annual multi-purpose CSO survey of the services sector. The ASI was a precursor to the Business Energy Use survey. Detailed fuel purchase costs were collected in occasional years prior to 2009. Since then only the total cost of fuel purchases was collected each year. The CSO used pre-2009 enterprise-level profiles to distribute the total fuel purchase costs across energy products at enterprise level and then used unit costs to estimate quantities. More generalised profiles were used for enterprises that could not be matched with pre-2009 ASI returns. Adjustments were made for some known fuel use trends that occurred after 2008 e.g. increased proportion of diesel vehicles.

ASI data was not used in cases where the enterprise was a respondent in the BEU survey or was included in the administrative data. The main purpose of using the ASI data was to get coverage across all services NACE Divisions especially medium and smaller sized enterprises. The ASI was particularly useful in 2010 when the services sector was not included in the BEU sample.

- Census of Industrial Production

The Census of Industrial Production is an annual multi-purpose CSO survey of enterprises with 10 or more employees. The CIP was a precursor to the Business Energy Use survey in so far as detailed fuel purchase costs were collected in occasional years prior to 2009. Since then only the total cost of fuel purchases was collected. The CSO used pre-2009 profiles to distribute the total fuel purchase costs across energy products at enterprise level and then used BEU unit costs to estimate quantities. More generalised profiles were used for enterprises that could not be matched with pre-2009 CIP returns.

CIP data was not used in cases where the enterprise was a respondent in the BEU survey or in the administrative data. The main purpose of using the CIP data was to get coverage across all industry NACE Divisions. The CIP was particularly useful in 2011 when the industry sector was not included in the BEU sample.

- Overview of Returns by Data Source at Enterprise Level

The following table indicates the number of enterprise returns used to compile the Business Energy Use survey results. To distinguish the ETS and non-ETS sectors, we classified all ETS returns as ETS. In contrast, in some cases where there was both LIEN and BEU data for an enterprise then if the BEU return was used, the source was described as BEU. The table shows how the inclusion of other data sources has greatly increased the effective sample to allow weighting to be done at NACE Rev. 2 Division level rather than at a more aggregated level. This more detailed level allows for more flexibility in aggregating the data e.g. energy industries.

Imputation

While the survey is enterprise focused, in some cases a fuel approach was needed to ensure that niche fuels were accurately included in the survey results e.g. wood waste. The CSO added a small number of imputed returns in cases where an annual survey return was not available for a company with very specialised energy use.

Some of the data sources had only quantity or monetary data and the CSO imputed the missing data using actual returns from other enterprises.

The fuels collected varied across each data source and in some cases the CSO imputed some data at fuel level as necessary to fill these gaps.

The breakdown of the ASI and CIP data by energy product was imputed using pre-2009 ASI and CIP data and BEU unit costs.

Explicit questions were not included in the survey for road transport fuels for 2009-2012 and for other transport fuels for 2009-2015. The CSO used a variety of data sources to produce estimates for these fuels.

The BEU sample excludes NACE sectors O (Public Administration), P (Education), and Q (Health and Residential Care). Hence data for these NACE sectors come from the Public Sector Energy Programme which has fuel quantities only. The CSO used BEU unit prices to estimate purchase costs for the PSEP returns.

Consumption units

A kilotonne of oil equivalent (ktoe) is a common unit of measurement which enables quantities of different fuels to be compared and aggregated. The following conversion factors were used:

NACE Rev. 2

The Statistical classification of economic activities in the European Community is NACE. The NACE classification is a way of categorising economic activities into a common structure. The survey data were weighted at NACE division level as this allows more flexibility in combining different NACE divisions and is more useful for compiling energy accounts and using the results in National Accounts Supply and Use tables.

In energy and emission inventory statistics, Transport is used to represent transport fuels rather than the NACE meaning of the transport sector. In the BEU results, transport fuels used by other NACE sectors were assigned to the NACE sector of the reporting enterprise. For example, road transport fuels used by waste collection vehicles were attributed to the NACE Rev.2 classification for the waste industry.

Revisions

Some 2009-2015 data may be revised when the 2016 or 2017 results are published. Aviation, marine, and rail fuels were not asked as explicit questions in the 2009-2017 surveys. These fuels will be collected in explicit questions in a pilot 2018 survey. If possible a time series for marine fuels will be compiled for a future release.

Renewable Fuels

Road diesel is pre-blended with biodiesel before being sold on forecourts. Hence purchases at forecourts include some amount of renewable fuels (around 5%). The CSO has not made an adjustment to the autodiesel figures to account for this mixing hence our estimate for biodiesel is lower than the actual levels and our estimate of road diesel is correspondingly higher.

The range of renewable fuels being used has broadened considerably in recent years. Amendments were made to the questionnaire to reflect this trend e.g. taking some fuels out of drop-down menus to ask them as individual questions.

Road Transport Fuels

These were not explicitly collected in the 2009-2012 BEU surveys hence the results presented for those years should be treated with caution as they were mainly compiled from the other data sources. In some cases a BEU respondent provided data for road fuel in the 2009-2012 surveys e.g. under diesel. The CSO reassigned such fuel to autodiesel if it was possible to identify it or if the respondent had submitted a comment to that affect with the survey return e.g. a return from a road haulier which contained a large quantity under diesel.

Rail Transport Fuels

There were no explicit questions on rail fuels in the 2009-2015 questionnaire however some enterprises submitted data under items such as diesel. The results are derived from a mixture of the survey data and other administrative data including company reports.

Aviation Transport Fuels

There were no explicit questions on aviation fuels in the 2009-2015 questionnaire however some enterprises submitted data under items such as kerosene. The CSO examined returns from airline companies and used additional data on flights by Irish airlines to estimate the quantity and cost of these fuels.

The estimates are based on the National Accounts residence principle. Hence fuel consumption relating to flights by Irish airlines between two foreign countries are included. This methodological difference has resulted in a substantial difference with the Energy Balance estimates for these fuels.

Marine Transport Fuels

There were no explicit questions on marine fuels in the 2009-2015 questionnaire and there is limited data available from other sources. There are no figures for marine fuels included in this release.

County

Tables 7A and 7B classify activity by the county that the headquarters of an enterprise is located in. All activity of an enterprise is located to the same county even if there are local units in other counties. A small number of enterprises used addresses abroad. 

Energy Balances

The CSO compared the results with the SEAI energy balances. There are methodological differences between both series e.g. definition of the Transport sector and the residence versus territorial principle. There is good alignment for some fuels and differences for other fuels between both series. The resolution of these differences could result in future revisions to the CSO figures.
