Energy Policy Statistical Support Unit (EPSSU) FAQ


What is the remit of the Energy Policy Statistical Support Unit (EPSSU)?

SEAI has a lead role in developing and maintaining comprehensive national and sectoral statistics for energy production, transformation and end use. This data is a vital input to meeting international reporting obligations, for advising policy makers and informing investment decisions. Based in Cork, EPSSU is SEAI’s specialist statistics team. Its core functions are to:

  • Collect, process and publish energy statistics to support policy analysis and development in line with national needs and international obligations
  • Conduct statistical and economic analyses of energy services sectors and sustainable energy options
  • Contribute to the development and promulgation of appropriate sustainability indicators

Detailed complete timely and reliable statistics are essential to monitor the energy situation at a country level as well as at an international level.  Energy statistics on supply, trade, stocks, transformation and demand are indeed the basis for any sound energy policy decision. 

A profound knowledge of energy supply and demand including energy dependency, security and efficiency as well as environmental concerns requires detailed and reliable data. 

National Energy Statistical System (NESS)

EPSSU conducts the following Surveys:

  • Monthly surveys
  • Under the Energy Statistics Regulation we collect data on a monthly basis on:
  • Gas supply (t-1)
  • Electricity supply (t-1)
  • Electricity Generation fuel inputs (t-3)
  • Solid Fuel supply (t-3)
  • Quarterly surveys
  • Fuel cost comparison (scheduled prices for the first day of the quarter), published on SEAI website here.
  • Energy Prices and Taxes survey conducted for the IEA
  • Bi-annual Surveys
  • Price Directive – Electricity and Gas prices for domestic and industrial consumer prices under European Council Directive 90/377/EEC
  • Annual Surveys
  • CHP survey – survey of sites, installers and operators; CHP data is included annually in the Energy In Ireland report and the most recent CHP update report for 2008
  • Renewables Survey  – Imports, production, exports, total supply, total demand by sector; renewable data is included annually in the Energy Balance,  Energy In Ireland report and the most recent Renewable update report
  • Business Energy Use Survey - This survey was introduced in March 2010 as a joint venture with the Central Statistics Office (CSO).  This survey enables bottom up calculation of demand in the industry and services sectors.  Note the CSO are responsible for conducting this survey which is a sample survey using their Business Register.

Energy Balance

The balance is created from EPSSU survey data, with some modelling and estimated data.

The provisional balance is published on the 1st of April annually. The balance for year t-1 is finalised on year t.

The most up to date energy balance and the historical balance series are available here.

Specific queries on the energy balance can usually be answered through a search on the databank.

What is the EPSSU confidentiality Policy?

EPSSU have the same confidentiality policy as the Central Statistics Office (CSO) for Structural Business Statistics. Where data is not already in the public domain, such as through the emissions trading scheme (ETS), EPSSU cannot publish the data if there are less than 3 enterprises in the category or if one enterprise has more than 80% of a market share or two enterprises have more than 90%.

I have a policy question - can you help?

EPSSU provide ex-post and ex-ante evidence based analysis for policy decisions.  For policy documents and strategy document please contact the relevant government department.  Summaries of existing policies are contained in the relevant EPSSU publications.

Do you have statistics for regions/counties/cities in Ireland?

No. EPSSU only produce national energy statistics.
