Irish Domestic Smart Meter Data With Import and Export Readings

Ireland is the geographic scope for this dataset containing anonymized smart meter readings from 2,989 to 2,990 domestic consumers. It provides 30-minute interval data on electricity import from and export to the grid, with most files covering nearly two years. The data was collected via the elec-tariffs.ie platform operated by Dublin City University and is shared under a CC-BY-4.0 license.

Use Cases

• Analyzing daily and seasonal electricity consumption patterns using the 'Read Value' and 'Read Date and End Time' columns.
• Modeling the impact of residential solar or wind microgeneration by examining 'Active Export' events in the 'Read Type' column.
• Studying the effects of grid outages, such as Storm Eowyn in January 2025, by identifying gaps in the time-series data.
• Comparing energy usage profiles across anonymized households using the 'MPRN' user proxy identifier.
• Simulating and optimizing tariff plans for Irish consumers based on high-resolution import/export data.

Strengths

• Contains data from a large cohort of 2,989 to 2,990 individual households, providing a substantial sample for analysis.
• Offers high temporal resolution with 30-minute interval readings for most consumers over an approximately two-year span.
• Includes bidirectional energy flow data, capturing both consumption ('Active Import') and microgeneration export ('Active Export').
• Data collection is supported by a formal data altruism framework under the EU Data Governance Act via elec-tariffs.ie.

Limitations

• The exact row count is unspecified across allprovided sources, making precise volume assessment difficult.
• Data gaps exist due to power outages from events like storms, which may interrupt time-series continuity for some households.
• Sources slightly disagree on the consumer count, citing both 2,989 and 2,990, though the difference is minor.

Provenance

Source

Domestic consumers in Ireland via their ESB Networks accounts and the elec-tariffs.ie platform operated by Dublin City University.

Collection Method

Users voluntarily downloaded their smart meter data from ESB Networks and uploaded it to the elec-tariffs.ie website for tariff calculation, agreeing to anonymized public release.

Time Range

Approximately two years for the majority of consumer files, with specific events like Storm Eowyn recorded in January 2025.
