Ireland launches second tender for large-scale renewables projects

The Irish Department of the Environment, Climate and Communications has initiated the country's second auction for large-scale renewable energy projects under its Renewable Electricity Support Scheme (RESS) 2, with final results due in mid-June 2022. 

The RESS is an auction-based scheme, which invites renewable power projects to bid for capacity. Successful applicants receive a guaranteed price for the electricity they generate for 14 to 16.5 years, depending on project delivery dates. The scheme is open to a range of technologies, including wind and solar, with provisions to couple renewables and storage capability at project sites. The RESS 2 scheme removes the standalone solar preference category and uses instead an Evaluation Correction Factor (ECF), intended to reflect the relative benefits that each type of technology has on system costs. In its the first renewable auction, the country awarded 1,275 MW of generating capacity at an average weighted bid price reached €74.08/MWh.

The Irish authorities aim, under their Climate Action, to instal up to 2.5 GW of solar energy on the electricity system by 2030.
