Here is a list of the most common questions EPSSU receives, please check if your question is answered here or in any of the categories above prior to contacting the office by email (preferably) or phone.
- Where can I get statistics on SEAI run grant schemes?
- I am researching for a school/college project – can you help?
- Where can I get financial estimates on energy spend?
- Does your data include Northern Ireland?
- Do you have statistics for regions/counties/cities in Ireland?

- What is the most recent data available?
- What is a kilo-tonne of oil equivalent?
- I have a policy question, can you help?
- Do you also have energy forecasting information?
Where can I get statistics on SEAI run grant schemes?
The energy statistics office is responsible for national energy statistics only. We do not have metadata on individual SEAI grant schemes.
For any further information please contact the scheme administration directly.

I am researching for a school/college project – can you help?
The most effective method of dissemination for the EPSSU is through our suite of publications. Prior to contacting the office we would greatly appreciate if you check whether your specific question can be answered by reading the relevant publication from EPSSU or if the information is available from the databank. Most queries can be answered by reading the relevant publications:
List of EPSSU Publications
Source data for our publication are available to download and save from the databank in tabular or graphical format.
Click here for instructions on how to download data from the databank.
If your question remains unanswered please email epssu@seai.ie referencing the publication you have consulted and the relevant page/figure/table.

Where can I get financial estimates on energy costs and energy spend?
Energy Costs
A fuel cost sheet is updated every quarter. The costs are based on the scheduled costs as of the 1st day of every quarter. The results are published on the 1st day of the second month every quarter.
EPSSU also produce a bi-annual publication on Electricity and Gas Prices.
Data collected for the IEA energy prices and taxes survey is discussed in the annual Energy in Ireland publication.
Energy Spend
The energy policy statistical support unit (EPSSU) do not publish financial estimates due to the inherent inability to estimate all energy cost/spend. Fuel prices vary with time and volumes so it is very difficult to monitor accurately energy spend. Tax takes give estimations of volumes only not prices or spend.
We would be happy to oblige in further discussion on this topic but will not publish official energy spend estimates. Please contact epssu@seai.ie

Does your data include Northern Ireland?
No, the Sustainable Energy Authority of Ireland is only responsible for energy statistics in the Republic of Ireland. Energy statistics for Northern Ireland are compiled by the UK Department o f Energy and Climate Change (DECC).

Where can I get information on energy use? (Source data, time-series, graphs & charts)
It is most likely that the information you require is available on the databank hosted for SEAI on the CSO web pages. Click here for instructions on how to download data from the databank.

What is a kilo-tonne of oil equivalent?
A kilo-tonne of oil equivalent is a thousand (103) tonnes of oil equivalent. A tonne of oil equivalent is a conventional standardised unit of energy and is defined on the basis of a tonne of oil having a net calorific value of 41686kJ/kg. A related unit is the kilogram of oil equivalent (kgoe) where 1kgoe = 10-3 toe.
The International Energy Agency (IEA) has an on-line conversion tool in order to convert between energy units. Click on the following link:
http://www.iea.org/stats/unit.asp
Alternatively use the following table:
| To: | toe | MWh | GJ |
| From: | Multiply by |
| toe | 1 | 11.63 | 41.868 |
| MWh | 0.086 | 1 | 3.6 |
| GJ | 0.02388 | 0.2778 | 1 |
Energy Units:
joule (J): Joule is the international (S.I.) unit of energy.
kilowatt hour (kWh): The conventional unit of energy that electricity is measured and charged for commercially.
tonne of Oil Equivalent (toe): This is a conventional standardized unit of energy and is defined on the basis of a tonne of oil having a net calorific value of 41686 kJ/kg. A related unit is the kilogram of oil equivalent (kgoe), where 1 kgoe = 10-3 toe.

Do you also have energy forecasting information?
The SEAI Energy Modelling team established in 2009 specifically to meet this need, provides high-quality analysis and policy advice on a range of energy-climate issues at the national and European level. Click here for the modelling group webpage.
