5.3 Percentage of energy from renewable sources

Each MWh may only be counted once, i.e., in no more than one of the documentation fields provided. Note that electricity generated by on-site renewable systems is reported above for indicator 5.1. Energy attribute certificates (EACs) include RECs, GOs, and I-RECs.

Contractual instruments for renewable electricity
Energy attribute certificates (EACs) sold or not owned by the institution:
0 Megawatt-hours

Electricity from certified off-site renewable sources:
0 Megawatt-hours

Description of the certified off-site renewable sources of electricity:
---

Electricity from uncertified off-site renewable sources:
6,124 Megawatt-hours

Description of the uncertified off-site renewable sources of electricity:
EirGrid, the organisation that develop, manage and operate the electricity transmission grid in Ireland, reported that, in 2023, 40.7% of the electricity supplied in Ireland comes from renewable energy (Ref1 and Ref2 and Ref3).

Renewable stationary fuels

Convert all units to MWh using the STARS energy calculator or an equivalent resource. Include products sourced during the performance year for the purpose of producing electricity and/or thermal energy, irrespective of whether they were used or not.

Certified bioenergy products:
0.21 Megawatt-hours

Description of the certified bioenergy products:
The Department of the Environment, Climate and Communications and the Department of Agriculture, Food and the Marine reported the status of biomethane supplied in the gas network in Ireland. It reads that "The volume of biomethane injected into the grid is small, equating to c. 75 GWh per annum, which is equivalent to 0.001% of Ireland’s current gas demand." (Ref1)
