Monthly Oil Data. Deliveries into Ireland's Market

Recent Oil Product Deliveries

The top half of this panel shows the monthly totals of gross inland deliveries (GID) of the five major oil products to Ireland, over the latest twelve months for which data is available. Gross inland delivery is the quantity of each product flowing through the market from production to delivery that is ready for sale or consumption – see the end of this page for technical details on GID. The bottom half of this panel provides a provisional estimate of the CO₂ arising from oil combustion, both monthly and as the sum of the latest twelve months. The twelve-month total is a useful running indicator because it acts to average-out summer and winter consumption patterns. Estimates of CO₂ emissions based on monthly data are useful in giving 'fast feedback' and in highlighting seasonal patterns, but they are provisional results, not definitive results. The EPA’s GHG Inventory is the definitive source of CO₂ emissions in Ireland. The emission estimates in this panel act only to supplement and support the EPA’s definitive annual GHG inventory.

Recent Oil Product Deliveries - Emissions

The top half of this panel shows two sets of bubble plots. The top line of bubbles shows the summed emissions from different types of oil products, over the latest twelve months for which data is available. The bottom line of bubbles is similar but shows emissions from the single latest month for which data is available. The bottom half of this panel shows a stacked bar-chart of oil product emissions over the latest twelve months for which data is available, broken down by product type. Again, estimates of CO₂ emissions based on monthly data are useful in giving 'fast feedback' and in highlighting seasonal patterns, but they are provisional results, not definitive results. The EPA’s GHG Inventory is the definitive source of CO₂ emissions in Ireland. The emission estimates in this panel act only to supplement and support the EPA’s definitive annual GHG inventory. 

Recent Oil Product Deliveries - Breakdown

The top half of this panel shows the percentage-breakdown of oil product deliveries over the latest twelve months for which data is available. The bottom half of this panel shows a pair of pie-charts. The left pie-chart shows the percentage breakdown of oil product deliveries averaged over the latest twelve months for which data is available. The right pie-chart shows the same breakdown for the single latest month for which data is available.

Long Term Trends in Monthly Oil Deliveries - Total

The top half of this panel shows the monthly total of oil product deliveries going back several years. The bar-chart shows the total oil products delivered each month, and the black line shows a twelve-month moving-average of those values. The bar-chart element helps identify seasonal variations (and any short-term “shocks”) in the monthly total of oil products delivered. The moving average helps identify underlying long-term trends. To improve visual clarity, the latest calendar year is shown in orange, the previous calendar year in yellow, and all preceding years in different shades of blue. The bottom half of this panel shows the “seasonal envelope” of total of oil product deliveries over the last five years. This plot allows for easy comparison of total oil products delivered in a given month of the current year (orange) with the previous year (yellow) and the preceding years (blue). It also acts to highlight seasonal variations in the monthly total of oil product delivered across the twelve calendar months.

Long-term Trends in Monthly Oil Deliveries – By Product

This panel lets users choose a particular oil product (e.g. Heating Kerosene, Jet Kerosene, etc.) from the drop-down menu in the top right corner, to explore monthly deliveries from that oil product over several years. By default, the panel shows monthly deliveries of Heating Kerosene. The top half of this panel shows the monthly deliveries from the selected oil product going back several years. The bar-chart shows the deliveries from the selected oil product each month, and the black line shows a twelve-month moving-average of those values. The bar-chart element helps identify seasonal variations (and any short-term “shocks”) in the monthly deliveries of the selected oil product. The moving average helps identify underlying long-term trends. To improve visual clarity, the latest calendar year is shown in orange, the previous calendar year in yellow, and all preceding years in different shades of blue. The bottom half of this panel shows the “seasonal envelope” of the monthly deliveries of the selected oil product over the last five years.

It also acts to highlight seasonal variations in the monthly deliveries from the selected oil product across the twelve calendar months.

Long-term Trends in Monthly Oil Deliveries - Explorer

This panel allows users to select multiple oil products and explore the resulting sum of monthly deliveries from those oil products. Users can choose their preferred 'unit-of-supply' and zoom-in on a date-range that best suits their interest.

Changes in Monthly Oil Deliveries - Total

The top half of this panel shows the percentage change in monthly total of oil product deliveries generated relative to the previous month. For example, the percentage change value for April 2022 is the monthly total of oil product deliveries in April 2022, less the monthly total of oil product deliveries in March 2022, divided by the monthly total of oil product deliveries in March 2022. This plot helps identify the typical month-to-month variance in total oil product deliveries, which is typically in the +/-10% range. The bottom half of this panel shows the percentage change in monthly total of oil product deliveries relative to same month in the previous year. For example, the percentage change value for April 2022 is the monthly total of oil product deliveries in April 2022, less the monthly total of oil product deliveries in April 2021, divided by the monthly total of oil product deliveries in April 2021. This plot helps identify year-to-year changes in total oil product deliveries and underlying long-term trends. 

Changes in Monthly Oil Deliveries – By Product

This panel lets users choose a particular oil product (e.g. Heating Kerosene, Jet Kerosene, etc.) from the drop-down menu in the top right corner, to explore changes in monthly deliveries from that oil product over several years. By default, the panel shows the changes in monthly electricity generated from Motor Petrol. As above, the top half of this panel shows the percentage change in monthly deliveries from the selected oil product relative to the previous month. For example, the percentage change value for Motor Petrol in April 2022 is the monthly total of Motor Petrol delivered in April 2022, less the monthly total of Motor Petrol delivered in March 2022, divided by the monthly total of Motor Petrol delivered in March 2022. This plot helps identify the typical month-to-month variance in the deliveries from the selected oil product. The bottom half of this panel shows the percentage change in monthly deliveries from the selected oil product relative to the same month in the previous year. For example, the percentage change value for Motor Petrol in April 2022 is the monthly total of Motor Petrol delivered in April 2022, less the monthly total of Motor Petrol delivered in April 2021, divided by the monthly total of Motor Petrol delivered in April 2021. This plot helps identify year-to-year changes in the deliveries from the oil product. 

Monthly Oil Deliveries - Customizable Download

This panel allows users to download the data underlying all the data panels on this webpage. Users can select their preferred 'unit of supply' (including multiple units) and zoom-in on a date-range that best suits their interest. The table will then show the corresponding monthly totals for each of the oil products. Users can download the table as a CSV or XLSX crosstab by clicking on the small “Download” icon (rectangle with an arrow pointing down) at the bottom right of the panel. Again, please note that while CO₂ emission estimates based on provisional monthly are useful in giving “fast feedback” and in highlighting seasonal patterns, they are not definitive results. The EPA’s GHG is the definitive source of CO₂ emissions for Ireland. Due to a range of technical factors. the sum of SEAI’s provisional CO₂ emission estimates from January to December will not exactly equal the annual total of a given year. 

Interacting with the Monthly Data Panels

In many of the data panels below, users can interact and customise the data views to suit their needs. Users can choose the unit-of-measure for the plot – ktoe (kilotonnes of oil equivalent), GWh (gigawatt hours), or TJ (terajoules). In some panels users can use a “slider” to select and zoom-in on a particular date-range of interest. In many cases, hovering the cursor over an element of a plot in a panel will invoke a tool tip that provides numerical detail of the underlying element. Users can download a panel as an image file (PNG), or its underlying data (CSV or XLSX crosstab) by clicking on the small “Download” icon (rectangle with an arrow pointing down) at the bottom right of the panel. Alternatively, users can customise and download the underlying data for all panels on this page, by using the Monthly Oil Deliveries - Customizable Download panel. Due to the detailed nature of the plots and tables, and how tool tips are optimised for a mouse, rather than a finger, this page is best viewed on a monitor rather than a smartphone. 

Role and Value of Monthly Data

Provisional monthly data is not as robust as the definitive annual data published in SEAI’s Energy Balance or the EPA’s Greenhouse Gas Emission (GHG) Inventory. The surveys used to collect annual data are more inclusive and more exhaustive than those used to collect monthly data, and the detailed cross-agency reconciliation applied to annual data is not possible for monthly data. However, provisional monthly data has two advantages over annual data – it is available more quickly, and it allows seasonal variations (or market shocks, such as Covid-19 impacts) to be identified. The rapid provision of energy and emission data to Irish policymakers, journalists, researchers, and public is particularly important, given the relatively short 5-year windows of Ireland’s carbon budgets, and the significant emission reductions that need to be achieved within them. While CO₂ emission estimates based on provisional monthly are useful in giving “fast feedback” and in highlighting seasonal patterns, they are not definitive results. The EPA’s GHG is the definitive source of CO₂ emissions for Ireland. Due to a range of technical factors. the sum of SEAI’s provisional CO₂ emission estimates from January to December will not exactly equal the annual total of a given year. 

Data Provenance and Conversions

The five high-level oil products for monthly reporting are: 

• Road Diesel – The petrochemical component of the diesel used in our cars, trucks, trains, etc. 
• Motor Petrol - The petrochemical component of the petrol used in our cars, trucks, trains, etc. 
• Heating Kerosene – The oil product used in the majority of residential oil-boilers 
• Jet Fuel Kerosene – The high purity and regulated oil product used in aviation   
• Other Oils – All other oil products 

Monthly gross inland deliveries (GID) of oil products are determined by SEAI based on the aggregation of confidential submissions made by oil suppliers to Ireland’s Oil Levy Administration (OLA) database, which is administered and maintained by the Department of the Environment, Climate and Communications (DECC). SEAI determines and submits monthly gross inland deliveries of oil products to satisfy Ireland’s international reporting obligations under the 2008 European Energy Statistics Regulation. 

Gross inland deliveries are the quantities of oil-products flowing through the market from production to delivery that are now ready for sale or consumption. Refinery outputs, imports, and stock draws act to increase GID quantities. Exports, international marine bunkers (i.e. products purchased for and consumed by vessels carrying out international shipping), and stock-builds act to decrease GID quantities. Inter-product transfers describe the reclassification of products and are therefore reported as a negative value for one product, compensated by a positive value for another product. In its full form, gross inland delivery is defined as primary product receipts, plus refinery gross output, plus recycled products from the petrochemical sector, less fuels combusted in refineries, plus imports, less exports, less international marine bunkers, plus inter-product transfers (which may be positive or negative), less products transferred for use as refinery feedstocks, less (net) stocks changes. 

Oil delivery data is collected and published by SEAI on both a one-month and two-month retrospective basis. Highly provisional Joint Oil Data Initiative or “JODI” data is available within one month, and then overwritten by revised Monthly Oil Statistics “MOS” data, two months after the fact. 

For example, data for March (i.e. covering oil deliveries between 01-MAR and 31-MAR) is typically published on 30-APR based on available “JODI” data and revised on 31-MAY based on available “MOS” data. As a result, the very latest monthly oil deliveries are based on “JODI” data, and all preceding months are based on “MOS” data. The exact date of publication is dictated by the timeliness of accurate submissions by oil suppliers to the OLA database. SEAI would like to thank all energy suppliers that participate in its statistical surveys. 

Oil delivery data is sourced from the OLA database in units of volume (i.e. litres) and mass (i.e. tonnes) depending on the oil product, with SEAI making the conversion to TJ, ktoe and GWh, to comply with international reporting obligations. Monthly oil delivery data is published in terms of net calorific value (NCV). 

SEAI makes simple provisional estimates of the CO₂ emissions from the Monthly oil deliveries by applying a weighted effective emission factor. Emissions from the combustion of oil products are spread across multiple sectors in Ireland’s 2021-2025 carbon budget – transport, electricity, residential, commercial, industry, etc. The EPA’s GHG Inventory is the definitive source of CO₂ emissions for Ireland. The energy emission estimates on this page, based on provisional monthly energy data from SEAI, act only to supplement and support the EPA’s definitive annual GHG inventory. SEAI’s provisional monthly emission estimates will be overwritten by the EPA’s definitive GHG inventory.
